Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric blind device, and more particularly to a plurality of electric blinds provided corresponding to a plurality of windows facing outdoors, respectively, and covering a plurality of windows. The present invention relates to an electric blind device capable of operating the plurality of electric blinds.

[0002]

2. Description of the Related Art An electric blind device of this type has an electric blind installed in a window of a building, and is configured to be able to operate such an electric blind.
This type of electric blind may be installed in each of a plurality of windows provided in a building. Therefore, in such a case, it has been considered to collectively control the operations of the plurality of electric blinds. For example, Japanese Unexamined Patent Publication
No. 17584 discloses that the operation of a plurality of electric blinds provided in a window of a building is collectively controlled by a central controller provided in one place for the purpose of drawing characters and the like on the wall surface of the building with room light. A technique for performing this is disclosed.

[0003] Further, in such an electric blind, it is possible to introduce outdoor wind indoors by opening a slat. For example, Japanese Unexamined Patent Publication No. Hei 6-17584 discloses that an indoor wind force is detected, and when the detected wind force is equal to or less than a predetermined value, it is determined that the wind is introduced from outside to indoors.
A technique is disclosed in which the angle of a slat of a specific blind for wind introduction is adjusted in accordance with a detected wind force so that the blind can be ventilated, and the wind is introduced indoors.

As described above, in the conventional electric blind device, it is considered that the electric blind of a specific window is operated in a permeable state to control the wind to be introduced indoors.

[0005]

However, the conventional control for introducing wind into a room is performed according to the wind detected indoors, and a specific window for wind introduction is to be controlled. there were. For this reason, in the conventional control, although it is possible to simply introduce wind into the room, efficient natural ventilation using the wind cannot be performed indoors for the following reasons. That is, in the conventional control, since only the entrance of the wind is formed by the operation of the electric blind, it is difficult to introduce the wind when the wind is weak. In addition, in the conventional control, since a wind state such as an outdoor wind direction is not considered, if a specific window for wind introduction is not located on the windward side due to the outdoor wind state, there is sufficient wind outdoors. Nevertheless, wind is difficult to introduce. As described above, the conventional electric blind device cannot perform efficient natural ventilation indoors according to the outdoor wind condition.

The present invention has been made to solve such a problem. A main object of the present invention is to provide an electric blind device capable of efficiently performing indoor natural ventilation.

[0007]

According to a first aspect of the present invention, there are provided a plurality of electric blinds provided corresponding to a plurality of windows facing the outdoors, each covering a corresponding window. An electric blind device capable of operating the plurality of electric blinds, a wind direction detecting means for detecting an outdoor wind direction, a wind speed detecting means for detecting an outdoor wind speed, and each of the plurality of electric blinds capable of passing through. Control means capable of performing control for operating in a normal state or in a state in which ventilation is impossible, wherein the operation control means detects a predetermined wind speed or more by a wind speed detection means in a state where a plurality of windows are opened. When the wind speed is detected, based on the wind direction detected by the wind direction detection means at the time of the wind speed detection,
Among the plurality of electric blinds, the operation control for ventilation is performed such that the electric blind provided on the window on the leeward side and the electric blind provided on the window on the leeward side are operated to allow ventilation.

[0008] Based on the wind direction detected when a wind speed equal to or higher than a predetermined wind speed is detected, of the plurality of electric blinds, the electric blind provided on the windward window and the electric blind provided on the leeward window are provided. Since the blind is operated to allow ventilation, a wind inlet is formed on the windward side and a wind outlet is formed on the leeward side according to the wind direction. For this reason, since the wind easily passes through the indoor, even when the wind of the wind blowing outdoors is weak, natural indoor ventilation using the wind can be easily performed. Therefore, indoor natural ventilation can be efficiently performed.

According to a second aspect of the present invention, in addition to the configuration of the first aspect, when the operation control means performs the operation control for ventilation, the number of the electric blinds on the windward side is larger than that on the leeward side. While operating to allow ventilation,
Control is further performed to operate the electric blind provided in the leeward window located at a displaced position that does not face from the front to the windward window in which the corresponding electric blind is operated to allow ventilation.

[0010] On the windward side, a larger number of electric blinds than the leeward side are operated so as to be able to ventilate, so that the amount of wind introduced increases. Further, on the leeward side, since the electric blind provided in the displaced position that does not face the front from the front of the window in which the electric blind is operated to be able to ventilate on the leeward side is operated in a ventilable state, The range of the space where the wind flows indoors is expanded.
For this reason, even when the wind of the wind blowing outdoors is weak, natural ventilation using the wind can be more efficiently performed indoors.

According to a third aspect of the present invention, in addition to the configuration according to the first aspect, when the operation control means performs the operation control for ventilation, the operation control means is most distant between the windward side and the leeward side. Control is further performed to operate the electric blinds provided in each of the windows in a positional relationship so that they can be ventilated.

For this reason, the range of the space in which the wind flows can be expanded, for example, the wind can flow from the corner on the windward side indoors to the corner on the leeward side indoors. Even when the wind force is weak, natural ventilation using wind can be performed more efficiently, such as natural ventilation can be performed to the corners inside the room.

According to a fourth aspect of the present invention, in addition to the configuration of the first aspect, the apparatus further includes a sunshine direction detecting means for detecting a sunshine direction, wherein the operation control means includes: When the side in the sunshine direction detected by the detecting means coincides with the windward side, the electric blind provided in the window closest to the windward side among windows located at positions not corresponding to the side in the sunshine direction, and the window Control to operate the electric blind provided on the leeward side window at the position furthest away from the vehicle, respectively, so that the sunshine direction side detected by the sunshine direction detection means coincides with the leeward side. The electric blind provided on the window closest to the leeward side of the windows located at positions not corresponding to the sunshine direction, and the electric blind provided on the windward window located farthest from the window And Rind further performs control to operate the ventilation ready respectively.

That is, in the control for allowing the electric blinds on the leeward side and the leeward side to operate in accordance with the wind direction, when the side of the sunshine direction coincides with the leeward side or the leeward side, one of the leeward side and the leeward side is selected. On the side receiving the sunshine, the electric blind of the window closest to the sunshine side can be ventilated, avoiding the sunshine. And the electric blind provided in the window furthest from the window provided with the electric blind which can be ventilated on the side receiving the sun on the side receiving no sun among the windward side and the leeward side Are set to be able to ventilate.

As described above, since the electric blinds provided in the windows which are located as far apart as possible between the windward side and the leeward side can be ventilated, the indoor windward side is provided. The wind can be passed from the corner to the leeward corner in the room, and the range of the space where the wind flows can be expanded, so even if the wind force blowing outdoors is weak, the wind is used. Indoor natural ventilation can be performed more efficiently. In addition, since the electric blinds on the windward or leeward side can be ventilated in a manner to avoid sunshine, indoor shade can be performed in addition to natural ventilation.

According to a fifth aspect of the present invention, in addition to the configuration of the first aspect, a plurality of electric blinds are provided corresponding to each of the plurality of electric blinds. It further includes a plurality of fault detecting means for detecting that a fault has occurred in the elevating operation. further,
Each of the plurality of electric blinds has slats, and the slats are at an angle allowing ventilation, or
By setting the slats in the raised state, it is possible to enter a state in which ventilation is possible. Further, when the operation control means controls the electric blind to be able to ventilate in the ventilation operation control, the electric blind to be controlled is temporarily moved up and down with the slat at an angle at which the ventilator can ventilate. If the failure detection means detects that a failure has occurred in the elevating operation, all the electric blinds to be controlled are operated in a state in which the slats are raised so that ventilation can be performed. If the failure detection means does not detect that a failure has occurred in the elevating operation, all the electric blinds to be controlled are operated at an angle at which the slats can ventilate so that the air can be ventilated. Perform further control.

When controlling the electric blinds on the leeward and leeward sides to be able to ventilate according to the wind direction, the electric blinds to be controlled are temporarily raised and lowered with the slats of the electric blinds to be controlled at an angle allowing the ventilation. If any of the obstacle detection means detects that an obstacle has occurred in the ascent / descent operation during the ascent / descent, it can be determined that a strong wind that may deform the slats of the electric blind is blowing outdoors. If such a failure of the elevating operation is not detected, all the electric blinds to be controlled are operated at an angle at which the slat can ventilate so that the air can be ventilated. When a failure is detected, all the electric blinds to be controlled are operated in a state in which the slats are raised, so that ventilation is enabled. In other words, when it is determined that a strong wind is blowing outdoors, the slats are operated in a raised state, so that the slats are less likely to be affected by strong winds. , Can prevent deformation due to strong wind.

, 2n (n is an integer) are automatically controlled as described later.

The central controller 1 can also control the operation of the electric blinds 21, 22,... 2n according to the manual operation of the device designation switch 5 and the operation designation switch 6. The device specifying switch 5 is a switch for specifying an electric blind to be controlled by the MPU 4 among the electric blinds 21, 22,. The device designation switch 5 designates information on a device number attached to the electric blind to be controlled. The specification of the device number by the device specifying switch 5 is performed when the operation details are previously stored in the electric blind for automatic control before automatic control is performed, or when the electric blind is actually operated by manual control. .

The operation designation switch 6 is a switch for designating the operation content of the electric blind designated by the device designation switch 5. The operation contents here include “actual ascent (command to actually raise the electric blind)”, “actual descent (command to actually lower the electric blind)”, and “actual opening (actually, the slats of the electric blind are leveled horizontally). Angle command), "actual close (command to actually close the slats of the electric blind)", "actual stop (command to actually stop the electric blind)",
"Memory rise (command to store the operation of raising the electric blind)", "memory lowering (command to store the operation of lowering the electric blind)", "memory open (operation to set the slat of the electric blind to a horizontal angle is stored." Command), "memory closing (command for storing an operation of closing the slats of the electric blind)," and "storage data (command for performing an operation corresponding to the storage data)".

The wind direction and wind speed detector 8 includes a propeller type wind direction and wind speed meter, detects an outdoor wind direction and wind speed, and supplies a detection signal indicating wind direction and wind speed detection information to the MPU 4.
The wind direction detection information in this case is obtained by dividing the azimuth into eight equal angles with the wind speed detector 8 as a reference position, and indicating the wind direction by the eight divided directions.

When automatic control is performed, the MPU 4
A command signal for automatically controlling the electric blind is output based on a detection signal of the wind direction detector 8. In addition, the MPU 4 can output a command signal for performing manual control of the electric blind, and also output a command signal for storing in advance the operation content of each electric blind during automatic control in each electric blind. It is possible to

When automatic control is performed, a command signal for automatically controlling the electric blind is supplied from the MPU 4 to the transmission circuit 7. In the case where the storage setting of the operation content for the automatic control or the manual control is performed, when the device specifying switch 5 and the operation specifying switch 6 are operated, a command signal is output according to the operation state.
4 to the transmission circuit 7.

The command signal output from the MPU 4 includes a device designation data portion and an operation designation data portion. The device number of the electric blind to be controlled is specified by the device specification data section. The operation specification data section specifies the operation contents such as the above-described actual ascent, actual descend, actual open, actual close, actual stop, memorized descent, memorized open, memorized close, and memorized data. Such a command signal is provided from the MPU 4 to the transmission circuit 7, and is amplified by the transmission circuit 7. The command signal amplified by the transmission circuit 7 is transmitted to each of the electric blinds 21, 22, ... 2n via the communication line 3.

The communication line 3 connects the central controller 1 and each of the electric blinds 21, 22,... 2n by a so-called bus system. That is, the electric blinds 21, 22, ... 2n are connected to the central controller 1 in parallel. Therefore, the command signal output from central controller 1 is given to all electric blinds.

Each of the electric blinds 21, 22,... 2n has a similar configuration. Each electric blind is M
It includes a PU 9, a receiving circuit 10, a device number setting circuit 11, a memory circuit 12, a lifting / lowering / opening / closing encoder circuit 13, a driving circuit 14, and a motor 15 connected to the MPU 9. In each of the electric blinds, various operations such as a raising / lowering operation and an angle adjusting operation of the slats 20 a are performed in response to a command signal given from the central controller 1 by executing a control program in the MPU 9.

The device number of each electric blind is stored and set in the device number setting circuit 11 in advance. The memory circuit 12 stores an operation content for automatic control specified by the above-described command signal. The elevating / opening / closing encoder circuit 13 provides the MPU 9 with position data capable of specifying the current elevating state and the opening / closing state of the slat 20a. The raising / lowering operation and the opening / closing operation of the slat 20a of each electric blind are performed using the motor 15 as a drive source. That is, the lifting and lowering operation and the opening and closing operation of the slat 20a are performed in conjunction with the operation of the motor 15. And MPU9
The drive circuit 14 that operates in accordance with the control signal from the CPU controls the drive of the motor 15, so that the lifting and lowering operation and the opening and closing operation of the slat 20a are controlled.

In each electric blind, a command signal transmitted from the central controller 1 is received by the receiving circuit 10, and the received command signal is transmitted from the receiving circuit 10 to the MPU 9.
Given to. The MPU 9 analyzes the content of the received command signal, and controls the operation of the electric blind according to the analyzed content as follows. First, the device number specified by the device specifying data portion of the command signal is compared with the device number stored and set in the device number setting circuit 11 to determine whether or not they match.

If the device numbers do not match as a result of the comparison, the command signal does not target the electric blind, and the electric blind in that case does not perform an operation according to the command signal.

On the other hand, as a result of the comparison, if the device numbers match, the electric blind in that case performs an operation according to the operation content specified by the operation specification data portion of the command signal. Specifically, when an instruction to store the operation content is issued, such as “memory increase”, the MPU 9 stores the instructed operation content in the memory circuit 12. When an instruction to perform an operation according to the storage data is issued, such as “storage data”, the MPU 9
However, in order to perform automatic control in accordance with the operation content stored in the memory circuit 12, a control signal is supplied to the drive circuit 14 to control the drive of the motor 15. Also, "real rise"
When a manual control command is issued as described above, a control signal is supplied to the drive circuit 14 to drive and control the motor 15 in order to perform manual control according to the commanded operation content. As described above, when the motor 15 is driven and controlled to perform the lifting / lowering operation and the opening / closing operation of the slat 20a, the MPU 9 can specify the current lifting / lowering state and the opening / closing state of the slat 20a given from the lifting / lowering encoder circuit 13. The drive of the motor 15 is controlled while confirming the state of the slat 20a based on the position data, and the operation according to the command signal is executed.

Next, the installation state of the electric blind in the electric blind device according to the first embodiment will be described. FIG. 3 is a schematic diagram showing a simplified use state of the electric blind in the electric blind device according to the first embodiment. Specifically, FIG. 3 shows a state where the inside of the building is viewed from above in a plan view. here,
The installation state of the electric blind will be described with reference to FIG.
FIG. 3 is also used later for explaining the operation of the electric blind device.

Referring to FIG. 3, in a building 200 having a square planar shape, a window 20 is provided at the center of each of the four walls.
1 is provided. Among these windows 201, the windows of the first wall and the second wall facing the first wall include:
Electric blind 21 in which the device number of “device 1” is set
Is installed. In addition, the windows of the third wall between the first and second walls and the fourth wall facing the third wall include:
Electric blind 22 in which the device number of “device 2” is set
Is installed. Therefore, in this case, when “device 1” is selected, the electric blinds 21 and 21 of the two opposing windows are simultaneously operated. On the other hand, when “device 2” is selected, two opposing windows are selected. Electric blind 22,
22 will be operated simultaneously. In this case, in the control circuit described above, two electric blinds 21 and two electric blinds 22 are provided.

The wind direction detected by the wind direction detector 8 is divided into eight directions A to H, as shown in FIG. In this case, two wind direction areas correspond to each wall. The directions in which one of the electric blinds 21 and 21 is provided are directions A and B, and the directions in which the other of the electric blinds 21 and 21 are provided are directions E and F.
It is. The direction in which one of the electric blinds 22, 22 is provided is the direction C, D, and the electric blinds 22, 2,
The directions in which the other of the two is provided are directions G and H.

As described above, in the first embodiment, the electric blind 21 of the device number of “device 1” is
In addition, an example is shown in which a total of four electric blinds are provided with two electric blinds 22 having an apparatus number of “Equipment 2”.

Next, the contents of the control operation of the electric blind device according to the first embodiment will be described. FIG. 4 is a flowchart showing the contents of the control operation of the electric blind device according to the first embodiment.

FIG. 4 shows the flow of the control operation of the electric blind device in steps S1 to S7, in which S1 to S4 correspond to the MPU 4 on the central controller 1 side.
S5 to S7 are the control operations of the MPU 9 on the side of the selected electric blind. Here, in order to show the flow of a series of control operations, the central controller 1
The entire control operation including the control operation of the electric blind and the control operation of the selected electric blind is shown in one flowchart.

As a prerequisite in this case, in each electric blind, an operation for setting the slat 20a to a horizontal angle state (an operation corresponding to the above-mentioned memory opening) or an operation for automatically controlling the memory circuit 12 is performed. Slat 2
The operation of setting 0a to the raised state (the operation corresponding to the above-described storage increase) is stored in advance.

First, in step S1, the wind speed detected by the wind direction and wind speed detector 8 is equal to or higher than a predetermined value (a wind speed value at which indoor ventilation can be performed by allowing the electric blind to pass through). Is determined. When it is determined in step S1 that a wind speed equal to or higher than a predetermined value is detected, in step S2, the wind direction detected by the wind direction wind speed detector 8, that is, the windward direction is the direction A, B, E, or F. A determination is made as to whether any of these are true.

If it is determined in step S2 that the windward direction corresponds to any one of the directions A, B, E, and F, the direction in which one of the electric blinds 21 and 21 of the device 1 is provided is the windward direction. And the direction in which the other is provided is the leeward side. Therefore, in this case, in step S3, a process of selecting the device 1 and transmitting a command signal for operating the electric blinds 21 and 21 of the selected device 1 according to the storage operation is performed. Thereby, the command signal is transmitted from the central controller 1 to each electric blind.

On the other hand, if it is determined in step S2 that the windward direction does not correspond to any of the directions A, B, E and F, one of the electric blinds 22 of the device 2 is provided. The direction is the leeward side, and the other direction is the leeward side. Therefore, in that case,
In step S4, the device 2 is selected, and the selected device 2
A process of transmitting a command signal for operating the (electric blinds 22, 22) according to the storage operation is performed. Thereby, the command signal is transmitted from the central controller 1 to each electric blind.

According to step S3 or step S4,
When the command signal is transmitted, the electric blind of the device number selected and designated by the command signal performs the control operation of steps S5 to S7. In the electric blind of the selected and designated device number, in step S5, the data of the operation content stored in the memory circuit 12 is read, and it is determined whether or not the storage of the operation content is an ascending operation.

If it is determined in step S5 that the operation is ascending, in step S6, the slat 20a is moved to the ascending position as shown in FIG. 1C in the electric blind of the device number selected and designated. Is performed. On the other hand, if it is determined in step S5 that the operation is not an ascending operation, that is, if the storage of the operation content is an operation of setting the slat 20a to a horizontal angle, the operation proceeds to step S7 in the electric blind of the device number selected and designated. Processing for operating the slat 20a at a horizontal angle as shown in FIG. 1B is performed. As described above, the electric blinds of the windows on the windward and leeward sides are controlled to be able to ventilate by being set to the raised position or the horizontal angle. In this case, the electric blinds of the device numbers that are not selected have a closed angle as shown in FIG. 1A, and are not allowed to ventilate.

When the electric blind is controlled by such a control operation, for example, a wind flow as shown in FIG. 3 is obtained. In FIG. 3 described above, as an example, the manner in which the wind flows when the direction A or the direction B is windward is indicated by arrows. Referring to FIG. 3, for example, when the wind blows from direction A or direction B, the electric blinds 21 and 21 as devices 1 are operated by the above-described control operation so that air can be passed through. Thereby, the electric blind 2
One of the air outlets 1 and 21 serves as a wind inlet and the other air outlet. Then, wind flows from the electric blind 21 on the leeward side to the electric blind 21 on the leeward side, and indoor natural ventilation is performed.

As described above, according to the first embodiment, the electric blind on the leeward side and the electric blind on the leeward side can be ventilated according to the wind direction. A wind inlet is formed, and a wind outlet is formed on the leeward side. For this reason, since the wind easily passes through the indoor, even when the wind of the wind blowing outdoors is weak, natural indoor ventilation using the wind can be easily performed. Therefore, indoor natural ventilation can be efficiently performed.

As a prerequisite in this case, in each electric blind, an operation for setting the slat 20a to the horizontal angle state (an operation corresponding to the above-mentioned memory opening) or an operation for automatically controlling the memory circuit 12 is described in the memory circuit 12. Slat 2
The operation of setting 0a to the raised state (the operation corresponding to the above-described storage increase) is stored in advance.

First, in step S8, the wind speed detected by the wind direction and wind speed detector 8 is equal to or more than a predetermined value (a wind speed value at which indoor ventilation can be performed by making the electric blinds ventilated). Is determined. If it is determined in step S8 that a wind speed equal to or greater than the predetermined value has been detected, step S8 determines whether the windward direction of the wind direction detected by the wind direction wind speed detector 8 corresponds to one of the directions A and B. A determination is made as to whether or not it is.

If it is determined in step S8 that the windward direction corresponds to one of the directions A and B, the first electric blind 21 that is the device 1 is provided.
Is the leeward side, and the second wall side provided with one electric blind 21 is the leeward side. In this case, in step S12, a process of selecting the device 1 and transmitting a command signal for operating the electric blinds 21, 21, 21 of the selected device 1 according to the storage operation is performed. Thereby, a command signal for operating the device 1 is transmitted from the central controller 1 to each electric blind.

On the other hand, if it is determined in step S8 that the windward direction does not correspond to any of the directions A and B, the windward direction of the wind direction detected by the wind direction wind speed detector 8 is determined in step S10. A determination is made as to whether any of C and D is applicable. In step S10, when it is determined that the windward direction corresponds to one of the directions C and D, the side of the third wall provided with the two electric blinds 22 as the device 2 is the windward side, and The side of the fourth wall provided with one blind 22 is the leeward side. In this case, in step S13, the device 2 is selected, and the electric blinds 22, 22, 2 of the selected device 2 are selected.
Then, a process of transmitting a command signal for operating the second device in accordance with the storage operation is performed. Thereby, the command signal for operating the device 2 is transmitted from the central controller 1 to each electric blind.

On the other hand, if it is determined in step S10 that the windward direction does not correspond to any of the directions C and D, the windward direction of the wind direction detected by the wind direction wind speed detector 8 is determined in step S11. A determination is made as to whether any of E and F is applicable. If it is determined in step S11 that the windward direction corresponds to one of the directions E and F, the side of the second wall provided with the two electric blinds 23 as the device 3 is the windward side, and The side of the first wall provided with one blind 23 is the leeward side. In this case, in step S14, the device 3 is selected, and the electric blinds 23, 23, 2 of the selected device 3 are selected.
Then, a process of transmitting a command signal for causing the storage device 3 to operate according to the storage operation is performed. Thereby, a command signal for operating the device 3 is transmitted from the central controller 1 to each electric blind.

On the other hand, when it is determined in step S11 that the windward direction does not correspond to any of the directions E and F, the windward direction of the wind direction detected by the wind direction / wind speed detector 8 is the direction of the direction G or H. Either. In this case, the side of the fourth wall provided with two electric blinds 24 as devices 4 is the windward side, and the side of the third wall provided with one electric blind 24 is the leeward side. In this case, in step S15, a process of selecting the device 4 and transmitting a command signal for operating the electric blinds 24, 24, 24 of the selected device 4 according to the storage operation is performed. Thereby, a command signal for operating the device 4 is transmitted from the central controller 1 to each electric blind. Step S1
When the command signal is transmitted in any one of steps S2, S13, S14, and S15, the MPU 9 of the electric blind having the device number selected and designated by the command signal performs steps S16 to S1.
8 is performed. In the electric blind of the device number selected and designated, the memory circuit 1
2 is read, and it is determined whether or not the storage of the operation content is an ascending operation.

If it is determined in step S16 that the operation is ascending, in step S17, the slats 20a are used in the electric blind of the device number selected and designated.
Is moved to the raised position as shown in FIG. 1 (c). On the other hand, if it is determined in step S16 that the operation is not the ascending operation, that is, if the storage of the operation content is the operation of setting the slat 20a to the horizontal angle, the operation proceeds to step S18 in which the electric blind of the device number selected and designated is used. The slat 20a is shown in FIG.
A process for operating the camera at a horizontal angle as shown in FIG. As described above, the electric blinds of the windows on the windward and leeward sides are controlled to be able to ventilate by being set to the raised position or the horizontal angle. In this case, the electric blinds of the device numbers that are not selected have a closed angle as shown in FIG. 1A, and are not allowed to ventilate.

When the electric blind is controlled by such control operation, for example, a wind flow as shown in FIG. 5 is obtained. In FIG. 5 described above, as an example, the flow direction of the wind when the direction A or the direction B is windward is indicated by arrows. Referring to FIG. 5, for example, when the wind blows from direction A or direction B, electric blinds 21, 21, 21 which are devices 1 are operated by the above-described control operation so that ventilation is possible. Thereby, the two electric blinds 21 and 21 of the first wall serve as wind inlets,
One electric blind 21 of the second wall serves as a wind outlet. By forming the wind introduction port and the discharge port in such a manner, each of the two electric blinds 21 and 21 at the corners at both ends on the windward side is directed toward one electric blind 21 at the central part on the leeward side. The wind flows and natural ventilation is performed indoors.

In this case, since the number of wind inlets on the windward side is larger than the number of wind outlets on the leeward side, the size of the wind inlet is larger than the size of the wind outlet. Be enlarged. For this reason, the amount of wind introduced can be made larger than in the case of the first embodiment. In this case, the position of the wind outlet is set to a position not facing the wind inlet from the front. For this reason, since the wind flows in a longer stroke than when the wind flows between the facing inlet and the outlet, the range of the space in which the wind flows for ventilation can be further expanded. Therefore, indoor natural ventilation can be performed more efficiently.

As described above, according to the second embodiment, in addition to the electric blinds on the windward side and the electric blinds on the leeward side being able to ventilate according to the wind direction, in addition to the windshield, The number of wind inlets is made larger than the number of wind outlets on the leeward side, and the position of the wind outlet is set to a position that does not face the wind inlet from the front. For this reason, the amount of wind introduced is increased and the range of the space through which the wind flows is increased, so that even when the wind blowing outdoors is weak, the natural ventilation using the wind should be performed more efficiently. Can be.

In this case, in step S47, a process of selecting the device 2 and the device 6 and transmitting a command signal for operating the electric blind 22 of the selected device 2 and the electric blind 26 of the device 6 according to the storage operation is performed. You.
Thereby, a command signal for operating the device 2 and the device 6 is transmitted from the central controller 1 to each electric blind.

If it is determined in step S32 that the windward direction does not correspond to any of the directions B and F, the windward direction of the wind direction detected by the wind direction wind speed detector 8 is determined in step S33. A determination is made as to whether any of C and G is applicable.

In step S33, if it is determined that the leeward direction corresponds to one of the directions C and G, one of the directions C and G is the leeward side and the other is the leeward side. In this case, in step S40, the sunshine direction detector 1
It is determined whether or not the sunshine directions detected by steps 6 are directions C and D. When it is determined in step S40 that the sunshine directions are the directions C and D, the direction C, which is either the windward side or the leeward side, matches the sunshine direction. In this case, the processing described above is performed in step S46 described above.

On the other hand, if it is determined in step S40 that the sunshine directions are not the directions C and D, it is determined in step S41 whether the sunshine directions detected by the sunshine direction detector 16 are the directions G and H. Is determined. If it is determined in step S41 that the sunshine directions are the directions G and H, the direction G, which is either the windward side or the leeward side, matches the sunshine direction. In this case, the processing described above is performed in step S45 described above.

On the other hand, when it is determined in step S41 that the sunshine direction is not the directions G and H, neither the windward side nor the leeward side coincides with the sunshine direction. In this case, in step S48, a process of selecting the device 3 and the device 7 and transmitting a command signal for operating the electric blind 23 of the selected device 3 and the electric blind 27 of the device 7 according to the storage operation is performed. You.
Thereby, a command signal for operating the devices 3 and 7 is transmitted from the central controller 1 to each electric blind.

If it is determined in step S33 that the leeward direction does not correspond to any of the directions C and G, one of the directions D and H is the leeward side and the other is the leeward side. In this case, the sunshine direction detected by the sunshine direction detector 16 is changed to the directions C and D in step S34.
Is determined. When it is determined in step S34 that the sunshine directions are the directions C and D, the direction C, which is either the windward side or the leeward side, matches the sunshine direction. In this case, the processing described above is performed in step S42 described above.

On the other hand, if it is determined in step S34 that the sunshine directions are not the directions C and D, it is determined in step S35 whether the sunshine directions detected by the sunshine direction detector 16 are the directions G and H. Is determined. If it is determined in step S35 that the sunshine directions are the directions G and H, the direction H, which is either the windward side or the leeward side, matches the sunshine direction. In this case, the processing described above is performed in step S43 described above.

On the other hand, when it is determined in step S35 that the sunshine direction is not the directions G and H, neither the windward side nor the leeward side coincides with the sunshine direction. In this case, in step S49, a process of selecting the device 4 and the device 8 and transmitting a command signal for operating the electric blind 24 of the selected device 4 and the electric blind 28 of the device 8 according to the storage operation is performed. You.
As a result, a command signal for operating the devices 4 and 8 is transmitted from the central controller 1 to each electric blind.

When the command signal is transmitted in any one of steps S42 to S49, the MPU 9 of the electric blind having the device number selected and designated by the command signal is sent to step S5.
The control operation of 0 to S52 is performed. In the electric blind of the device number selected and designated, in step S50, the data of the operation content stored in the memory circuit 12 is read, and it is determined whether or not the storage of the operation content is an ascending operation.

If it is determined in step S50 that the operation is an ascending operation, then in step S51, the slat 20a is turned on the electric blind of the device number selected and designated.
Is moved to the raised position as shown in FIG. 1 (c). On the other hand, if it is determined in step S50 that the operation is not an ascending operation, that is, if the storage of the operation content is an operation of setting the slat 20a to a horizontal angle, the operation proceeds to step S52 in which the electric blind of the device number selected and designated is used. The slat 20a is shown in FIG.
A process for operating the camera at a horizontal angle as shown in FIG. As described above, the electric blinds of the windows on the windward and leeward sides are controlled to be able to ventilate by being set to the raised position or the horizontal angle. In this case, the electric blinds of the device numbers that are not selected have a closed angle as shown in FIG. 1A, and are not allowed to ventilate.

As described above, in this control, basically, similarly to the third embodiment, the electric blind (for example, the electric blind 21) at the corner (corner) on the windward side indoors, Downwind corners (corners) indoors
Of the electric blinds (for example, the electric blind 25) are operated for ventilation. In addition, in this control, when the windward direction or the leeward direction coincides with the sunshine direction, the electric blind (for example, the electric blind 21 or 25) of the window in the sunshine direction is not operated. Blinds provided in windows closest to the windward or leeward side of the windows that do not correspond to the side of the direction, which coincide with the sunshine direction, such as the electric blind 2
4 or 28) is operated for ventilation. That is,
When operating the electric blind for ventilation on the windward and leeward sides, when the windward direction or the leeward direction coincides with the sunshine direction, do not operate the electric blind of the window on the side of the sunshine direction for ventilation. Instead, the electric blind of the window on the shade side closest to the windward or leeward side, which coincides with the direction of sunshine, is operated for ventilation.

When the electric blind is controlled by such a control operation, for example, a wind flow as shown in FIG. 10 is obtained. In FIG. 10 described above, as an example,
When the direction A is windward and the directions E and F are sunshine directions, the manner in which the wind flows is indicated by arrows. Referring to FIG. 10, for example, when directions E and F are on the sunshine side and the wind blows from direction A, the above-described control operation allows electric blind 21 as device 1 to be in a state where ventilation is possible on the windward side. The electric blind 24, which is the device 4, is operated so as to be able to ventilate on the windward side so as to avoid sunshine.

Thus, the two electric blinds 21 on the first wall serve as wind inlets, and the electric blinds 24 on the third wall serve as wind outlets. By forming the wind inlet and outlet in such a manner, the wind flows diagonally from the electric blind 21 at the windward corner to the electric blind 21 at the central corner at the leeward side, Indoor natural ventilation is provided. In this case, the electric blind 25 on the side receiving sunshine is not operated and is closed in a closed angle state.

In this case, as in the case of the third embodiment, the wind flows widely to the leeward corner (corner) farthest from the leeward corner (corner) indoors. For this reason, since the wind flows to every corner in a longer stroke than when the wind flows between the facing inlet and outlet, the range of the space in which the wind flows for ventilation can be further expanded. Therefore, indoor natural ventilation can be performed more efficiently. Furthermore, since the electric blind on the side receiving sunshine is closed in a closed angle state, indoor light shielding can be performed.

As described above, according to the fourth embodiment, in addition to the electric blinds on the windward side and the electric blinds on the leeward side being able to ventilate according to the wind direction, in addition to the indoor windshield, Since the wind is made to flow widely in the leeward corner (corner) farthest from the upper corner (corner), the range of the space through which the wind flows is expanded, so that the wind blowing outdoors Even when the wind is weak, natural ventilation using the wind can be more efficiently performed indoors.In addition, the electric blind can be ventilated while avoiding sunshine, so that indoor shade can also be performed. it can.

Fifth Embodiment Next, a fifth embodiment will be described. First, a control circuit of the electric blind device according to the fifth embodiment will be described. FIG. 12 is a circuit diagram showing a configuration of a control circuit of the electric blind device according to the fifth embodiment. 12, the same parts as those in FIG. 2 are denoted by the same reference numerals, and the description of the common parts will not be repeated.

The control circuit of FIG. 12 differs from that of FIG. 2 in the following points. Each electric blind is a fault detector 17
Contains. The failure detector 17 is a sensor that detects the occurrence of a failure when the slat 20a moves up and down. Specifically, the failure detector 17 has a microcomputer for failure determination, and is configured to be able to detect the occurrence of a failure based on the operation state of an operation mechanism related to the elevating operation of the slat 20a. I have.

In this case, a disk having a slit formed on the shaft (rotating shaft) of the motor 15 is attached.
Based on the pulse signal generated by the photo interrupter in response to detecting light passing through the slit by projecting and receiving light on the disk, the rotation speed of the disk, that is, the rotation speed of the shaft, is detected. Is done. When the slat 20a hits an obstacle while ascending, and the rotation speed of the shaft decreases, the generation of the pulse signal is delayed. Therefore, when it is determined that there is a delay, the microcomputer for obstacle determination is used to raise the pulse signal. Is detected. Further, the obstacle detector 17 is also configured to be able to detect the loosening of the lifting tape for lifting and lowering the slat 20a. When the slat 20a is falling, the lifting tape is hit by an obstacle and the lifting tape is loosened. In this case, the failure determination microcomputer detects the occurrence of the failure during the descent.

When a fault is detected, the fault detector 17 supplies a detection signal to the MPU 4. In MPU4,
When a failure is detected by the failure detector 17, control is performed to operate the electric blind for ventilation so that the slat 20a is not deformed due to the occurrence of the failure, as described later.

In the fifth embodiment, control contents will be described for the case where the installation state of the electric blind in the electric blind apparatus is the same as that shown in FIG. 3 according to the first embodiment.

Next, the contents of the control operation of the electric blind device according to the fifth embodiment will be described. FIG.
It is a flow chart which shows the contents of the control operation of the electric blind device by an embodiment.

In FIG. 13, steps S53 to S6
4 shows the flow of the control operation of the electric blind device, in which S53 to S56 are the control operations of the MPU 4 on the side of the central controller 1, and S57 to S64 are the control operations of the MPU 9 on the side of the selected electric blind. Operation.
Here, in order to show a flow of a series of control operations, one flowchart shows the entire control operation including the control operation of the central controller 1 and the control operation of the selected electric blind.

First, in step S53, the wind speed detected by the wind direction / wind speed detector 8 is equal to or higher than a predetermined value (a wind speed value at which indoor ventilation can be performed by making the electric blinds ventilated). A determination is made as to whether the When it is determined in step S53 that a wind speed equal to or greater than the predetermined value has been detected, in step S2, the wind direction detected by the wind direction wind speed detector 8, that is, the windward direction corresponds to the directions A, B, E, and F. A determination is made as to whether any of these are true.

If it is determined in step S2 that the windward direction corresponds to any one of the directions A, B, E, and F, the direction in which one of the electric blinds 21 and 21 of the device 1 is provided is changed to the windward direction. And the direction in which the other is provided is the leeward side. Therefore, in this case, in step S55, a process of selecting the device 1 and transmitting a command signal for operating the electric blinds 21 and 21 of the selected device 1 is performed. Thereby, the command signal is transmitted from the central controller 1 to each electric blind.

On the other hand, if it is determined in step S57 that the windward direction does not correspond to any of the directions A, B, E, and F, one of the electric blinds 22 of the device 2 is provided. The direction is the leeward side, and the other direction is the leeward side. Therefore, in this case, in step S56, a process of selecting the device 2 and transmitting a command signal for operating the selected device 2 (the electric blinds 22, 22) is performed. Thereby, the command signal is transmitted from the central controller 1 to each electric blind. When the command signal is transmitted in step S55, the electric blinds 21, 21 of the device 1 selected and designated by the command signal are moved to steps S57, S59, S6.
1, the control operation of S62 is performed. In step S57, the electric blinds 21 and 21 move up and down with the slats 20a at a horizontal angle as shown in FIG. 1B. Then, in S59, it is determined whether or not a failure has been detected by the failure detector 17 during such ascent and descent. When the slat 20a is moved up and down in a state where the slat 20a can be ventilated at a horizontal angle, the above-described obstacle is detected because strong wind is blowing outdoors and the slat 20a is blown by the wind and hits an obstacle. This is the case. . Therefore, in such a case, the slat 20
If a is lowered, the slats 20a may be deformed by the strong wind.

Therefore, if a fault is detected by the fault detector 17 during the ascent and descent in S59, the electric blinds 21 and 21 move the slats 20a to the raised position as shown in FIG. A process for operating is performed. In other words, when strong wind is blowing outdoors,
By setting the slat 20a to the raised position, a state is provided in which ventilation is possible for ventilation. On the other hand, if no failure is detected by the failure detector 17 during the ascent and descent in S59, the electric blinds 21 and 21 return the slats 20a to the original state in S62, that is, as shown in FIG. A process for returning to a state where the horizontal angle has been made is performed.
That is, when a strong wind is not blowing outdoors, the slats 20a are set to a horizontal angle, thereby achieving the first state.
As in the case of the embodiment, the slats 20a are set in a state where they can be ventilated for ventilation.

When the command signal is transmitted in step S56, the electric blinds 22, 22 of the device 2 selected and designated by the command signal are sent to the above-described step S56.
Control operations similar to the control operations of 57, S59, S61, and S62 are performed in steps S58, S60, S63, and S64.

As described above, in the fifth embodiment, when the electric blind on the windward side and the electric blind on the leeward side can be ventilated for ventilation according to the wind direction, first, the control target is controlled. It is determined whether or not a strong wind that may deform the slats 20a by temporarily moving the electric blind up and down is blowing outdoors. Then, when it is determined that a strong wind is blowing, the slat 20a is set in an ascending state so that the electric blind to be controlled can be ventilated. On the other hand, when it is determined that the strong wind is not blowing, the slat 20a is moved. By setting the horizontal angle, the electric blind to be controlled can be ventilated.

As described above, when the strong wind which may deform the slat 20a is blowing outdoors, the electric blind which is operated for ventilation is provided to the slat 20a.
Is raised, the slats 20a are less likely to be affected by the strong wind, so that the slats 20a operated for ventilation can be prevented from being deformed by the strong wind.

Therefore, according to the fifth embodiment, in addition to the effect that indoor natural ventilation can be efficiently performed even when the wind blowing outdoors is weak,
The effect that the deformation of the slat of the electric blind operated for ventilation can be prevented can be obtained.

In the first to fifth embodiments, a wind direction / wind speed detector 8 capable of detecting the wind speed and the wind direction by one device is used as means for detecting the wind speed and the wind direction outdoors. An example was given, but not limited to this.
The outdoor wind speed and the outdoor wind direction may be respectively detected by individual detectors.

In the first to fifth embodiments, when the wind direction is detected, which of the eight divided directions corresponds to the wind direction is obtained as a detection result. The invention is not limited to this, and the division manner is not limited to eight directions, and a detection manner in which the directions are divided in such a manner may not be used. That is, the wind direction may be detected in any detection mode as long as the wind direction can be specified.

As described above, according to the present invention, when wind having a wind speed equal to or more than a predetermined value is blown, the electric blinds on the windward side and the leeward side are controlled to be able to ventilate according to the wind direction at that time. Accordingly, a wind inlet is formed on the windward side and a wind outlet is formed on the leeward side according to the wind direction. For this reason, since the wind easily passes through the indoor, even when the wind of the wind blowing outdoors is weak, the natural indoor ventilation using the wind can be efficiently performed.

Further, when controlling the electric blinds on the windward and leeward sides to be able to ventilate according to the wind direction,
On the leeward side, a greater number of electric blinds are operated to allow ventilation than the leeward side, and the corresponding electric blinds are operated to allow ventilation. Control is performed to operate the electric blind provided in the side window so that air can be passed through. For this reason, the amount of wind introduced is increased and the range of the space through which the wind flows is increased, so that even when the wind blowing outdoors is weak, the natural ventilation using the wind should be performed more efficiently. Can be.

Further, in order to control the electric blinds on the windward side and the leeward side to be able to ventilate according to the wind direction,
Like the positional relationship between the leeward corner (corner) farthest from the leeward corner (corner) indoors, there is the most distant positional relationship between the leeward and leeward sides. Control is performed to operate the electric blinds provided in each of the windows so that they can be ventilated. For this reason, since the range of the space through which the wind flows is expanded, even when the wind force blowing outside is weak, the natural ventilation inside the room using the wind can be more efficiently performed, for example, ventilation can be performed to the corners inside the room. Can do it.

Furthermore, when controlling the electric blinds on the leeward and leeward sides to be able to ventilate according to the wind direction,
Like the positional relationship between the leeward corner (corner) farthest from the leeward corner (corner) indoors, there is the most distant positional relationship between the leeward and leeward sides. Controls the electric blinds provided in each of the windows so that they can be ventilated.In addition, when the windward or leeward side is in the sunshine direction, the window corresponding to the sunshine direction is provided. Instead of the electric blind, the shade-side electric blind provided in the window closest to the window is controlled to be able to ventilate. For this reason, by expanding the range of the space through which the wind flows, even when the wind power blowing outdoors is weak, the natural ventilation using the wind can be performed more efficiently. An effect that light can be shielded can be obtained.

Further, when controlling the electric blinds on the leeward and leeward sides to be able to ventilate according to the wind direction,
Once, first, it is determined whether or not a strong wind that may cause deformation of the slats of the electric blind is blown outdoors by raising and lowering while keeping the electric blind of the controlled object in a state in which ventilation is possible, and that the strong wind is blowing When it is determined, the slat is operated in the up state to control the electric blind to be controlled so as to allow the ventilation. For this reason, when the strong wind which may deform the slat is blowing outdoors, the electric blind operated for ventilation is operated in a state where the slat is raised, so that the slat is less affected by the strong wind Therefore, it is possible to prevent the slats of the electric blind, which can be ventilated, from being deformed by strong wind.

It is needless to say that the present invention is not limited to the above-described embodiments, but can be variously modified and implemented within the scope of the claims.
