PROBLEM TO BE SOLVED: To reduce the standby power of electric equipment related to a power line transmission signal transmission/reception system, and at the same time to automatically recognize the correspondence between a plug socket and the electric equipment. SOLUTION: In the connection apparatus 3 for interposing the connection with a power line 2, current sensors 9A, 9B, and 9C and switches 8A, 8B, and 8C are provided for each of plug sockets 4A, 4B, and 4C. At the same time, a control section 10 is provided, where the control section 10 detects a detection signal from the current sensors 9A, 9B, and 9C and controls the opening/closing of the switches 8A, 8B, and 8C. The control section 10 associates the plug sockets 4A, 4B, and 4C with the electric equipment by a detection signal and an equipment signal from the electric equipment that is connected to each of the plug sockets 4A, 4B, and 4C, and outputs a correspondence signal related to the association to a home server 5. Additionally, when the electric equipment is in a standby state, the switches 8A, 8B, and 8C are closed to prevent standby power from being generated. |
