Characterized in that configured.

As described above, the line suitable for sharing and using the signal transmission line among the lines installed inside the house is the power line 30. The reason is that the power line 30 is installed in almost all spaces such as inside a living space or a door. This is because they can be used easily and in any space.

The present invention will be described in detail, and different unique IDs are allocated to the signal transmitters 20a, ..., and 20n, and the control unit 26 of the signal transmitters 20a, ..., 20n sets these different unique IDs.

The controller 46 of the signal receiver 40 sets the number of signal transmitters 20a,..., 20n connected through the power line 30.

In this state, data transmission and reception are performed between the plurality of signal transmitters 20a,..., 20n and the signal receiver 40 through the power line 30, but are transmitted and received in a predetermined order.

That is, between the signal receiver 40 and the signal transmitters 20a,..., And 20n, real-time bidirectional communication is performed in a predetermined order. At this time, the control unit 26 of the signal transmitters 20a,..., 20n analyzes the received data. Determining the type of transmission data, the power line communication unit 24 performs communication in the form of a response to an inquiry of the signal receiver 40.
