DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric blind, and in particular, a plurality of blinds are provided in each of a plurality of sections, and the blinds included in each section or in all sections are raised and lowered and the blades are opened and closed. Related to electric blinds to do.

[0002]

2. Description of the Related Art An electric blind having a conventionally proposed system configuration has a control device in which a relay or the like for controlling ascending, descending and stopping is provided inside a head box or the like. Then, the respective relays are connected in parallel to form a system, and these are connected to switches as command means corresponding to ascending, descending, and stopping, respectively.

[0003] On the other hand, in some buildings, rooms are divided into sections, and when installing blinds in windows belonging to each section, it is necessary to install the system configured as described above as many as the number of sections required. (For example, Japanese Patent Application Showa 6
No. 3-16510).

[0004]

In the conventional electric blind constructed as described above, it is necessary to connect a relay or the like provided inside a head box or the like in parallel between the respective electric blinds. It was complicated and required a great deal of time and money for construction. In addition, relays corresponding to rising, stopping, and lowering are required, and the work of increasing the cost of the electric blind and assembling and wiring the relays is also complicated.

Further, since the conventional electric blinds are connected in parallel with each other, even when they can be operated in conjunction with each other when a command is given from the command means, the blinds can be raised, stopped and stopped individually. In order to enable the descent, a plurality of command means for each electric blind is required.Because it is necessary to connect the electric blinds in correspondence with these command means, wiring work becomes more complicated and construction cost is increased. Is even higher,
The construction days also require many periods.

[0006] The wiring system of the conventional electric blind is as follows.
Since a high-voltage power supply such as a commercial power supply is used, special consideration is required for withstand voltage and safety, and the cost is also high in this aspect. In any case, the conventional electric blind is expensive and has been an obstacle to popularization.

Also, there are many fluctuations in the tenants inside the building, and therefore it is necessary to change the classification of the blinds for each tenant. However, as described above, the construction is difficult and costs are incurred each time. Was uneconomical. In addition, the conventionally proposed electric blind is equipped with a microcomputer to overcome the above-mentioned disadvantages and to reduce the workability and cost.

However, when the tenant in the building changes, the blind is absolutely specified in the patent, and the master unit and the slave unit need to be set. actually,
With a dip switch built in the blind body, the zone setting must be changed for the master unit and the slave unit number setting must be changed for the slave unit. In addition, another parent machine occurs at one parent machine, or it is changed to a child machine,
Further, when the slave unit is changed to the master unit (each setting can be easily changed by a dip switch), the wiring of the worst signal line must be changed.

In recent intelligent buildings,
They are double-glazed and often have blinds between them, in which case they are completely sealed and the dip switches cannot even be changed for the blinds themselves.

As described above, it is not always easy to change the division by changing the tenant or the like in the building, and a trouble such as construction work (although it is relatively simple) or a wiring change at worst occurs.

Therefore, the main purpose of this occurrence is to reduce the wiring work and shorten the work period, and at the same time, it is inexpensive, and the control for each section and all the blinds can be controlled collectively. It is to provide an electric blind.
