Whether the received command signal from the controller 4 commands the ascent/descent of the blind and the opening/closing of the blades in the appropriate segment is judged by a judging means, if so, the appropriate blinds are raised or lowered by a raising/lowering means and the blades are opened/closed by an opening/closing means.

Description

[Detailed Description of the Invention] [Field of Industrial Application] This invention relates to electric blinds, and in particular, a plurality of blinds are provided in each of a plurality of categories, and a denomination is provided in each category or in all categories. This invention relates to electric blinds that raise and lower the blind and open and close the blades.

[Conventional technology]

In conventionally proposed system-structured electric blinds, a control device is constructed by providing a relay for controlling raising, lowering, and stopping inside a head box or the like.

A system was constructed by connecting each relay in parallel, and these were connected to switches serving as command means for raising, lowering, and stopping, respectively.

On the other hand, in some buildings, rooms are divided into categories, and when installing blinds on windows belonging to each category,
The system configured as described above will be installed for as many divisions as are required (for example,
(See No. 10).

[Problem to be solved by the invention]

In conventional electric blinds configured as described above, it is necessary to connect relays installed inside the head box etc. in parallel between each electric blind, and such wiring becomes complicated and difficult to install. This required a great deal of time and money. Relays for raising, stopping, and lowering were still required, which increased the cost of electric blinds and complicated the work of assembling and wiring the relays.

Furthermore, since conventional electric blinds are connected in parallel, even though they can operate in tandem when a command is given or removed from the command means, each individual blind can be raised, stopped, and lowered individually. In order to do this, multiple command means for each electric blind are required, and it is necessary to connect the electric blinds in correspondence with each of these command means, which makes the wiring work even more complicated and the construction cost even higher. Become,
Construction also requires a long period of time. In addition, the wiring system of conventional electric blinds uses a high-voltage power source such as a commercial power source, requiring special consideration for voltage resistance and safety, which also increases costs. In any case, conventional electric blinds are expensive, which has been an obstacle to their widespread use.

In addition, the number of tenants inside a building changes frequently, so it is necessary to change the classification of blinds for each tenant, but as mentioned above, the construction is difficult and it is unnecessary to incur costs each time. It was the economy.

In addition, in conventionally proposed electric blinds,
Equipped with a microcomputer, it overcomes the above-mentioned drawbacks and reduces workability and costs.

However, if the tenant in the building changes, the specification of blinds is an absolute specification according to the patent, and settings for the parent unit and child unit are required.

In reality, you must change the zone settings for the parent device and the child device number settings for the child device using the dip switch built into the blind body. Also, base unit 1
If another master unit appears at the base, or if the slave unit changes to a slave unit, or if the slave unit changes to the master unit (each setting can be easily changed using the dip switch). ), in the worst case, the wiring of the signal line must be changed.

In addition, recent intelligent buildings have double-paned windows, and blinds are often installed between the windows.In this case, the blinds are completely sealed, and it is not even possible to change the dip switch for the blinds themselves.

In this way, it is not always easy to change the classification due to a change in the number of tenants in a building, and it may require construction work (although it is relatively easy) or, in the worst case, a change in wiring.

Therefore, the main purpose of this invention is to provide an electric blind that can reduce wiring work and shorten the construction period, is inexpensive, and can control each section and all blinds at once. It is to provide.

[Means to solve the problem]

The present invention is capable of arbitrarily specifying each category or all categories, and is provided with a command means for outputting a command signal for commanding raising and lowering of the ply seat and opening and closing of the blades.

On the other hand, each blind has a receiving means for receiving a command signal from the command means, and a determining means for determining whether the received command signal is a command to raise/lower the blind and open/close the blades in the corresponding category. , an elevating means for raising and lowering the blind in response to a determination that the command is to raise or lower a lift in the relevant category; It is composed of opening and closing means for opening and closing.

[Effect]

The electric blind according to the present invention receives a command signal in response to an arbitrary command to raise/lower the blind and open/close the blades for all classes, and to , if the command is to raise/lower and open/close the blades, the blind will be raised/lowered and the blades will be opened/closed.

1, each blind 01, 02. - Operate the device number setting section 51 of n to set the blind of, 02°..., n
Set the device number for each.

The classification controller 4 sets the start setting switch and the end setting switch of each of the classification keys to the corresponding classification in advance.

Next, the classification controller 4 is operated. That is, for example, by operating the key 210 of the category keys 2n that specifies the category 210 (conference room), (turning the start setting switch 4)
1, it is assumed that the end setting switch is set to 47 in advance. ) Next, if the operator wishes to lower the blind by operating the operation key 5n, the lowering key 504 is operated.

If you want to stop at a desired position, press the stop key 50.
Operate 3. Furthermore, when it is desired to raise the blinds on the 2nd floor all at once, the user operates the classification key 502 of the classification keys 2n, and then operates the rise key 502.

Furthermore, when closing the slats of all the blinds on the second floor, the user operates the classification key 212 and then operates the slat key 507.

As described above, when a command signal is input from the classification controller 4, the microcomputer 29 included in the classification controller 4 stores the command signal in its built-in memory. As shown in FIG. 8, the microcomputer 29 operates at a step (abbreviated as SP in the figure)
In step SP2, after a command signal is input from the classification key 2n, the start setting switch 3n (
After reading the contents of the end setting switch 4n (310 in the example) and the end setting switch 4n (410 in the example), it is determined in step SP3 that there is a key input from the operation key 5n. In step SP4, a command code corresponding to each command is outputted via the output section 31.

Next, referring to FIG. 9, each blind 01, 02,
..., n operations will be explained. The microcomputer 41 of the control section transmits data to the data input section 48 from the section controller 4 via the connection section 48 in step 5P21.
1 and stores it in the RAM 411. Then, in step 5P22, the microcomputer 41 compares the loaded command code with the device number set by the device number setting section 51.

Here, device codes TJs and Ue are set in the command code, and the range from the blind device number specified by the device code Us to the blind device number specified by the device code Ue is the target of operation. Therefore, in this case, although the device number has been set by the device number setting section 51, it will be compared with the device number specified by the command code Us=Ue. Command code US to Ue
(If it is not within the range, no operation is performed and the RAM 411 is cleared and the initial state is returned.

), in step 5P23, the blind is operated according to the instructions of the operation code C and the auxiliary operation code C3. That is, in step 5P24, the microcomputer 41 outputs a command signal to the motor control unit 53 to operate the motor 54 to raise and lower the blind, adjust the angle of the slats, and stop the blind.

Also, if the slat angle key 506 or 507 is operated after operating the classification key 212, all the blinds 01, 02... . It should be noted that the slat angle keys 506 and 507 continue to output the opening operation signal that is being operated, and when the operation is stopped and the input is stopped, the microcomputer 41 outputs a stop signal. At this point, the angle adjustment operation of each blind stops. Note that the above-described embodiments can also be applied to so-called roll blinds made of cloth installed in window openings of restaurants, hotels, and the like.

[Effect of the Invention J As described above, according to the present invention, it is possible to arbitrarily set a plurality of blinds for each category or all categories according to the command from the command means, and also to It can be easily changed, and the operation and settings of the blind body can be performed only by commands from the command means without changing the wiring, etc. The blind can be raised and lowered and the blades can be opened and closed, and the control is micro By using a computer, there is no need to use relays or the like as in the past, which not only reduces the work required for electrical wiring, but also makes the blind itself suitable for mass production, reducing costs.
