Description

Description: TECHNICAL FIELD The present invention relates to an electric blind, and more particularly, a blind provided in each of a plurality of sections and included in each section or in all the sections. The present invention relates to an electric blind that raises and lowers and opens and closes blades.

[Conventional technology]

A system-configured electric blind that has been proposed in the past constitutes a control device by providing a relay that controls ascent, descent, and stop inside a headbox or the like.

The respective relays are connected in parallel to form a system, and these are connected to switches as command means corresponding to rising, lowering and stopping respectively.

On the other hand, depending on the building, rooms are divided into sections,
When the blinds are installed on the windows belonging to each section, the system configured as described above is installed by the number of sections required (see, for example, Japanese Patent Application No. 63-16510).

[Problems to be Solved by the Invention]

In the conventional electric blind configured as described above, it is necessary to connect a relay provided inside the head box or the like in parallel between the electric blinds,
Such wiring is complicated and requires a lot of time and money for construction. Further, a relay corresponding to each of rising, stopping, and descending is required, and the cost of the electric blind is increased and the work of assembling and wiring the relay is complicated.

Furthermore, since the conventional electric blinds are connected in parallel, when a command is given from the command means, even if they can operate in conjunction, it is possible to raise, stop and lower each blind. In order to
Multiple command means are required for each electric blind, and since it is necessary to connect the electric blinds corresponding to each command means, the wiring work becomes more complicated, the construction cost becomes higher, and the number of construction days increases. Need a period of. Further, the wiring system of the conventional electric blind uses a high-voltage power source such as a commercial power source, and special consideration needs to be given to withstand voltage and safety, and in this respect, the cost is also high. In any case, the conventional electric blind is expensive and has been an obstacle to its popularization.

In addition, there are many changes in the tenants inside the building, so it is necessary to change the classification of blinds for each tenant, but as mentioned above, the construction work is difficult and it is not necessary to incur costs each time. It was an economy.

In addition, in the electric blinds that have been conventionally proposed,
It is equipped with a microcomputer to overcome the aforementioned drawbacks and to reduce workability and cost.

However, when the tenant in the building is changed, the blind designation is absolute designation in the patent, and it is necessary to set the master unit and the slave unit.

In practice, the DIP switch built in the blind body has to change the zone setting for the master unit and the slave unit number setting for the slave unit. In addition, base unit 1
When another base unit occurs at a base unit, is changed to a base unit, or is changed to a base unit (Each setting can be easily changed by a DIP switch.) In the worst case, the wiring of the signal line must be changed.

In addition, in recent intelligent buildings and the like, the windows are double windows, and blinds are often installed between the windows. In this case, the blinds are completely sealed, and the blind body cannot even change the DIP switch.

As described above, it is not always easy to change the classification by changing the tenants in the building, and it may be troublesome for construction (although it is relatively easy) or, in the worst case, the wiring may be changed.

Therefore, a main object of the present invention is to provide an electric blind which can reduce wiring work and can shorten the construction period, is inexpensive, and can collectively control all the blinds and control of each blind. Is to provide.

[Means for Solving the Problems]

The present invention is capable of arbitrarily designating the classification for each classification or all the classifications, and is provided with command means for outputting a command signal for commanding the raising and lowering of the blind and the opening and closing of the blades.

On the other hand, each blind has a receiving means for receiving a command signal from the commanding means, and a judging means for judging whether or not the received command signal is for instructing the raising and lowering of the blind and the opening and closing of the blade in the corresponding section. , The raising / lowering means for raising / lowering the corresponding blind in response to the fact that it is determined to be the raising / lowering command in the corresponding section, and the blade of the corresponding blind in response to the determination to be the instruction to open / close the blade in the relevant section. It is composed of opening and closing means for opening and closing.

[Action]

The electric blind according to the present invention receives a command signal in response to an instruction to move the blind up and down and to open and close the blades by category or all categories, and in the category to which the command signal belongs, If the command is to raise and lower and to open and close the blade, the blind is moved up and down and the blade is opened and closed.
