2. Description of the Related Art As a conventional wiring system in a building, for example, there is one described in Japanese Patent Application Laid-Open No. 4-250796. In this conventional system, a pair of signal lines are routed from a distribution board having a central control unit to a control terminal device for controlling the operation of a load and a monitoring terminal device connected to an operation switch, and It is connected to a wireless relay terminal device via a wireless signal line other than this signal line.
Then, the central control unit creates control data in response to a signal from the monitoring terminal according to the operation of the operation switch or a signal from the wireless relay terminal device according to the operation of the remote control switch, and controls the data. A time-division multiplexed signal is sent to the terminal to control the load.

[0003]

However, in the above-mentioned conventional wiring system, all the monitoring terminals and the control terminals are connected to the central control device of the distribution board, and At the same time, since wireless receivers arranged in various places in the building are also connected to the central control device of the distribution board, there are problems to be solved as listed below.

Since a large amount of wiring is required as a whole and a large number of wires are required to be connected, there is a risk that the amount of material will increase and the cost will increase, and the wiring will be troublesome. There is a risk that it will become long and there is a high possibility that construction errors will occur.

Since switch wiring for connecting the monitoring terminal connected to the distribution board and the operation switch is required, it is easy to change the position of the operation switch or add the operation switch after construction. I can't.

Most of the switch wiring is in-wall wiring, but when such in-wall wiring is performed, the switch may not be installed at a predetermined position due to a problem such as wall thickness.

The present invention has been made by paying attention to the above-mentioned conventional problems, and reduces the total amount of wiring and the number of wirings to reduce the cost and the labor of wiring, shorten the construction period, and reduce construction mistakes. In addition, it is possible to facilitate the change of the position of the switch and the addition of the switch, and to eliminate the wiring in the wall.

According to the present invention, load control means for controlling the supply of drive power to an electric load are connected to each other by two signal lines to enable bidirectional data transmission, and The above-mentioned object is achieved by wirelessly controlling the operation of the load control means with a remote control switch.

That is, in the wiring system of the present invention, the load control means, which is connected to the driving power source and is capable of controlling the operation of one or more electric loads such as the lighting or the ventilation fan, is optional in the building. A plurality of load control means are connected to each other by two signal lines to enable bidirectional data transmission, and at least one of the load control means is configured to receive a radio signal. The remote control switch for outputting a radio signal to the load control means is installed at a predetermined position in the building that requires control of the electrical load.

The load control means and the signal line are preferably arranged behind the ceiling of the building.

[0011]

In the construction, a plurality of load control means are installed at predetermined positions in the building, for example, in each area related to the arrangement of the electric load, and connected to the drive power source. The load control means are connected to each other by, for example, a signal line for transmitting data such as a time division multiplexed signal. Switch wiring for connecting the load control means and the operation switch is not provided.

When controlling the operation of the electric load, a remote control switch is operated to output a radio signal. This wireless signal is received by any load control means having a reception function, and the received load control means itself controls the operation of the electrical load according to the content of the wireless signal, or
If necessary, the received load control means transmits data to another load control means via a signal line, and the load control means that has received the data transmission controls the operation of the electrical load.

The corresponding adapter 11 among the adapters that have transmitted to 1 and 1n and received from the signal line 51 controls the load, but since the adapter 11 first receives the same signal and performs the load control, the load There is only one change in state. However, the above description assumes that the adapters 11 to 1n are within the communication area of the remote control switches 21 to 2n.

As described above, in the wiring system of the embodiment, the adapters 11 to 1n and the signal line 51 are arranged in the ceiling, and any one of the adapters 11 to 1n transmits a radio signal from the remote control switches 21 to 2n. Therefore, the wiring in the wall is not required, the installation position of the operation switch is not restricted, and the degree of freedom in design is improved.

Further, since the control signals are transmitted bidirectionally between the adapters 11 to 1n, the total amount of wiring is small and the number of wire connections is also small, which reduces the material and the cost. In addition, it is possible to reduce wiring work, shorten the construction period, and prevent construction errors.

Although the embodiment has been described above, the number of load connections of one adapter is not particularly limited, but it is preferable to set it to 1 to 5 in consideration of construction and product costs. In addition, the control signal sent from the remote control switch can be set for one load to multiple loads by setting the remote control switch, and depending on the setting, one load operation can be used to control all loads in the house. ON / O
It is also possible to perform FF control.

Since they are connected to each other and the operation of the load control means is wirelessly controlled by a remote control switch, the total amount of wiring can be reduced and the number of wire connections can be reduced, which reduces materials and costs. In addition to the above, it is possible to obtain the effect that the labor of wiring can be reduced, the construction period can be shortened, and construction errors can be prevented. Further, since the wired operation switch is not used, there is no restriction on the installation position of the operation switch, and there is an effect that the degree of freedom in design is improved. In addition, since the operation switch does not require wiring, it is possible to dispose the load control means and the signal line in the back of the ceiling and to eliminate the wiring in the wall as described in claim 2, and the degree of freedom of wiring Becomes higher.
