FIELD OF INDUSTRIAL APPLICATION This invention relates to an opening/closing drive control device, and more particularly to an opening/closing drive control device for driving controlled objects whose opening/closing operations or lifting/lowering operations are controlled in response to the rotation of an electric motor, such as electric blinds, electric roll screens, and electric curtains. The present invention relates to an opening/closing drive control device.

0002

[Prior Art] The use of electric opening/closing devices such as electric blinds, electric roll screens, and electric curtains that have been proposed and commercially available has greatly increased in proportion to the increase in the number of windows as buildings become taller. are doing. For example, electric blinds are fixedly attached to multiple window frames on each floor of a high-rise building. Each of these electric blinds is centrally controlled from a central control device for each floor or building, and can automatically prevent direct sunlight and afternoon sun from entering the room without having to manually open or close curtains. Therefore, it is effective from a cost perspective.

[0003] Now, in order to centrally control these multiple electric blinds for each floor or each window, it is necessary to specify each of the blinds in advance, and for this purpose, each blind is assigned an individual number in advance. Granted. The individual number was set by operating a dip switch fixedly provided for each electric blind. This individual number is data necessary when the central control device specifies and operates a specific blind from among a plurality of electric blinds.

[0004] Furthermore, there is a system disclosed in Japanese Patent Application Laid-open No. 192987/1993 that controls the opening and closing of a plurality of electric blinds in a centralized manner after individually assigning numbers to each of these blinds.

[0005]

[Problem to be Solved by the Invention] Conventionally, an individual number is set in advance for each electric blind as described above.
After setting the individual number, when changing the set individual number, the administrator goes to the installation location of the electric blind where the change is desired and operates the dip switch to change the number. There was a problem that it was inconvenient.

[0006] The above problem arises when it becomes necessary to change the individual numbers of multiple electric blinds individually and simultaneously due to changes in the layout of the floors of a building, etc.
There are also problems in that it consumes a large amount of labor and time, and is inferior in terms of practicality.

Therefore, it is an object of the present invention to set identification data for specifying each control object to each control object when driving and controlling a plurality of control objects that open and close electrically. An object of the present invention is to provide an opening/closing drive control device that allows easy setting changes.

[0008]

[Means for Solving the Problems] An opening/closing drive control device according to the present invention includes a plurality of control objects that are electrically operated to open and close, and is based on identification data assigned in advance to each of the control objects for identifying itself. This is an opening/closing drive control device that controls the drive of the plurality of control objects individually or in groups. Specifically, first transmitting means is portable and detachably provided to each of the controlled objects, and transmits the identification data inputted from the outside to each of the controlled objects; a second transmitting means connected via a path to transmit the identification data to each of the controlled objects, and each of the controlled objects receives the identification data transmitted from the first or second transmitting means. and an identification data storage means for storing the identification data while updating it in response to the identification data.

[0009]

Each of the electric blinds 3k includes an electric blind control section 8 (described later), although not shown. The control unit 8 is protected from the outside by a head box (not shown) that constitutes an outer box thereof, and
It is covered in one piece so as not to spoil its aesthetic appearance. The head box is fixed to the upper part of the window frame to which each electric blind 3k is attached. Note that a schematic configuration of the control section 8 will be described later.

The individual number setting device 2 and the controller 4 are miniaturized to be portable, and are detachably installed in the head box of each electric blind 3k.

The individual number setting device 2 is operated by hand to set the individual number Bk of each electric blind 3k, and displays a liquid crystal display 20 and a group designation key 21 that is pressed when designating the group number G. , when setting the group number G or unit number U designated by pressing the unit designation key 22, the numeric keypad 23, the designation key 21 or 22, which is pressed when designating the unit number U, to the corresponding blind 3k.

FIG. 2 is a schematic diagram showing the configuration of the control section 8 of each electric blind 3k shown in FIG. 1 above.

In FIG. 2, the control section 8 receives power supplied from a power supply 6 (not shown) and a CPU (abbreviation for central processing unit) 81 for controlling and managing the electric blind 3k itself. A power supply circuit 82 that supplies power necessary for driving each part, a drive circuit 83 that drives a motor, etc., an interface circuit 84 provided for transmitting and receiving signals with the central control device 1,
A controller circuit 85 provided for electrical connection with the controller 4, an individual number input/output circuit 86 provided for electrical connection with the individual number setting device 2, and data including an individual number Bk are stored. It is configured to include a memory circuit 87 provided for the purpose of. Each of the circuits 82 to 87 is connected to and controlled by the CPU 81. The memory circuit 87 also has an EEPROM (
Electric Erasable and
Programmable Read Only
Memory) or is backed up by a battery or the like.

The drive circuit 83 connects a geared motor composed of an electric motor and a reduction gear, and controls the rotation direction and rotation angle of the geared motor. The degree of raising or lowering of the blind is determined by the rotation angle of the geared motor, and the direction of raising or lowering of the blind is specified by the rotation direction.

The interface circuit 84 provides the CPU 81 with the individual number Bk and drive instruction signal given from the central control device 1. The CPU 81 decodes the applied drive instruction signal and controls the opening/closing drive of the blind via the drive circuit 83 accordingly. Also, CPU
81 writes and stores the given individual number Bk in a predetermined area of the memory circuit 87. As a result, the individual number Bk of the blind 3k that has already been written in the memory circuit 87 is overwritten and the data is updated.

The controller circuit 85 provides the CPU 81 with drive instruction signals (up, stop, down) from the controller 4. The CPU 81 converts a drive instruction signal given from the central control device 1 and controller 4 via the interface circuit 84 and controller circuit 85 into a control signal for driving the motor, and supplies it to the drive circuit 83. The drive circuit 83 controls the drive of the geared motor described above in response to the input of the control signal for driving the motor.

The individual number input/output circuit 86 inputs the individual number B designated by key input in the individual number setting device 2.
k is input and given to the CPU 81. The CPU 81 writes and stores the given individual number Bk in a predetermined storage area of the memory circuit 87. Further, when the confirmation key 25 is pressed in the individual number setting device 2, the individual number input/output circuit 86 responds to the memory circuit 87 via the CPU 81.
It operates to read out the individual number Bk currently set in and transmit it to the individual number setting device 2.

As described above, the signals from the central control device 1, the individual number setting device 2, and the controller 4 are fed all at once to the CPU 81 of each electric blind 3k. Each CPU 81 reads a code included in a given signal that specifies the signal transmission source, and determines which of the central control device 1, individual number setting device 2, and controller 4 the current received signal was sent from. It works to identify the

FIG. 3 is a process flow diagram for explaining the operation of each electric blind in the opening/closing drive control device according to an embodiment of the present invention.

The illustrated processing flow is stored in advance as a program in the memory circuit 87 of the control unit 8 of each electric blind 3k, and is executed under the control of the CPU 81.

Next, the procedure for setting and changing the individual number Bk of each electric blind 3k in the opening/closing drive control device according to an embodiment of the present invention will be explained with reference to FIGS. 1 and 2 and according to the processing flow in FIG. 3. do.

First, when the opening/closing drive control device is in its initial state, the individual numbers Bk of the electric blinds 3k included therein are all initially set to data 0. Therefore, in order to drive and control each electric blind 3k individually, it is necessary to set an individual number Bk to each electric blind 3k using the individual number setting device 2. Individual number B from individual number setting device 2
When an individual number setting signal including k is input, the control unit 8 of the electric blind 3k selects the currently set individual number B.
Change k to the newly given individual number Bk. This operation will be explained.

CPU 8 of the control unit 8 of the electric blind 3k
1 receives a signal from the individual number setting device 2 via the individual number input/output circuit 86, reads a code that specifies the transmission source included in the received signal, and sends the received signal to the central control device 1 and the individual number setting device 2. Number setting device 2 and controller 4
Determine from which source the message was sent.

First, the CPU 81 is normally in a standby state, but when it detects some kind of signal input, it goes to step S in FIG.
In the determination processing at step T1 (abbreviated as ST1 in the figure), step ST6, and step ST8, the source of the received signal is identified. In the case of setting the individual number Bk by the individual number setting device 2, the CPU 81 performs step S following step ST1.
In the process of T6, it is specified that the received signal is transmitted from the individual number setting device 2, so the processes from the next step ST7 are executed accordingly.

In the process of step ST7, the CPU
81 reads the content of the received signal from the individual number setting device 2 and determines whether or not the individual number Bk is set. At this time,
When the setting key 24 is pressed and it is determined that data regarding the new individual number Bk is included in the received signal, the CPU 81 stores the received new individual number Bk in the memory circuit 87 in the process of the next step ST10. The data is updated by overwriting the individual number Bk stored in .

[0035] In the process of step ST7, CP
U81 does not receive the data regarding the new individual number Bk and confirms that the individual number Bk is not set, that is, the confirmation key 2
When it is determined that 5 has been pressed, the process moves to step ST11, and the current individual number Bk is output. In other words, CPU8
1 accesses the memory circuit 87, reads the individual number Bk stored therein, and provides this to the individual number setting device 2 via the individual number input/output circuit 86. Therefore, the individual number Bk currently set for the electric blind 3k is displayed on the liquid crystal display 20 of the individual number setting device 2.

After the CPU 81 finishes the processing in step ST10 and step ST11, it returns to the processing in step ST1 again and prepares for receiving the next signal.

As described above, when the signal for setting the individual number Bk is input using the individual number setting device 2, the CPU 81 converts the individual number Bk currently stored in the memory circuit 87 into the newly given individual number. Update the data using In this way, if the individual number Bk is set as desired for all of the electric blinds 3k, the desired electric blinds 3k can be set individually or in a group in the opening/closing drive control device to which a plurality of electric blinds 3k are connected. and control becomes possible.

Next, a procedure for changing the individual number Bk set for each electric blind 3k will be explained.

It is assumed that the user knows in advance the individual number Bk set for each electric blind 3k using the individual number setting device 2.

First, the user inputs the individual number Bk currently set for the electric blind 3k for which the user wishes to change the individual number via the keyboard (not shown) of the central control device 1.
Enter data to instruct individual number change. In response to this, the central control device 1 creates a signal containing the individual number Bk to be changed and the data of the individual number change instruction, and sends it to the signal line 5. Since the creation signal arrives at all the electric blinds 3k connected to the signal line 5,
In response to the reception of the signal via the interface circuit 84, the CPU 81 of each electric blind 3k first executes the process of step ST1.

At this time, each CPU 81 executes step ST1.
In the process, the code for specifying the transmission source included in the incoming signal is read and it is determined that the transmission source is the central control unit 1, so that the processes from step ST2 onwards are executed accordingly.

In the process of step ST2, each CPU 81 reads the data of the individual number Bk specifying the destination included in the signal received from the central control unit 1, and temporarily stores it in the internal memory. After that, the memory circuit 87
The currently set individual number Bk is read from the , and this read individual number Bk is compared with the received individual number Bk stored in the internal memory to determine whether they match or not. It is determined whether the message was sent to . At this time, if the numbers match, the process branches to step ST3 and subsequent steps, which will be described later. However, if the comparison result shows that the two individual numbers do not match, it is determined that the current incoming signal is not sent to itself, and in response, the CPU 81 returns to the process of step ST1, Prepare for the next signal reception process.

The CPU 8 of the electric blind 3k has determined that the incoming signal from the central control device 1 is addressed to itself.
1 reads a code included in the received signal in the process of step ST3 following step ST2;
It is determined whether or not there is a command to drive (raise, lower, stop) the electric blind 3k. At this time, if it is determined that the operation command signal is included, the CPU 81 controls the motor etc. via the drive circuit 83 based on the received command signal in the process of step ST4 to open and close the electric blind 3k as desired. Drive.

On the other hand, in the process of step ST3, if it is determined that the incoming signal does not include an operation command signal, the process moves to the next step ST5. CPU
81 reads the new individual number Bk from the received signal and overwrites the individual number Bk stored in the memory circuit 87 in the process of step ST5, thereby changing and updating the individual number Bk.

For example, assume that the electric blind 34 with G=2 and U=1 in FIG. 1 is changed to G=1 and U=4. Next, when a command signal is sent from the central control device 1 to all G = 1 to raise all at once, the four electric blinds 31 to 34 corresponding to U = 1 to 4 of G = 1 all start raising simultaneously. (In the state before changing the individual number, the electric blind 3
4, because G=2, it was not possible to shift to an ascending operation with this command signal).It is also possible to change the entire group at once. For example, if you want to change all Group 2 to Group 1 in the state shown in Fig. 1, you can use the central controller 1 to input the individual number of the group you want to change (the group number is G=2, and the unit number is undefined) and the number of the individual number change. send a signal to that effect. When all the blinds of G=2 receive the new individual number Bk, they change the currently set individual number using the received new individual number. In this case, if G=1, U=+3 and individual numbers are sent, each blind of G=2 will have a group number of G=1.
is changed to G=2, and the unit number is updated by +3. That is, individual number Bk of G=2, U=1
The electric blind 3k that was given G = 1, U = 4
It is changed to (1+3). If there is no instruction of U=+3, the previous unit number remains. In this way, the individual number of each blind is determined for each blind (for each unit number U).
Alternatively, it can be changed in group units (for each group number G).

[0046] Step ST4 and Step ST5
After completing the process, the process returns to step ST1 and prepares for the next reception operation.

Next, the operation of controlling the electric blind 3k from the controller 4 will be explained.

The transmission signal from the controller 4 is given to the CPU 81 via the controller circuit 85. C.P.
U81 receives the signal from the controller 4 in step S.
It is determined in the process of step ST8 following step T1 and step ST6, and the process moves to step ST9 accordingly. In the process of step ST9, the CPU 81 decodes the received signal from the controller 4, drives and controls the motor via the drive circuit 83 based on the decoded data, and then returns to step ST1.

[0049] In the process of step ST9, if it is determined that the received signal is not a signal from the controller 4, the process returns to step ST1 again.

[0050]

As described above, according to the present invention, the setting and changing of the identification data specifying each of the control objects used when driving a plurality of control objects that are electrically operated to open and close can be performed by the first transmitting means. It is also possible to perform the operation via the second transmitting means, so that a person who wishes to operate each of the control objects does not have to go to the place where the control object is installed. This has the effect that the identification data can be set and changed by so-called remote control, and the degree of freedom is increased. Further, the above-mentioned effect also has the effect that buildings and systems equipped with the opening/closing drive control device can be managed and operated flexibly.
