REMOTE CONTROL SYSTEM OF INSTALLED EQUIPMENT IN BUILDING

摘要

PURPOSE:To control a remotely installed equipment by a radio with small-output by coupling transmitting master equipment with the base part of a power source line with a radio signal on which control signals are superposed and also providing a receiver, sending control signals of the transmitting master equipment which are outputted by a separately arranged transmitter through the power source line, and controlling the power source of equipment to be controlled. CONSTITUTION:The separate transmitter 5 is used nearby the transmitting master equipment 2 to send a radio control signal (a). At this time, transmitting master equipment 2 receiving the radio control signal (a) converts the signal to a specific frequency so that a control signal (b) is sent through the power line 1 and resend the signal. The control signal (b) sent through the power line 1 is decoded by a receiver 4 as a receiving terminal and control contents are indicated to the equipment 3 to be controlled, thereby powering down the objective equipment 3. In this case, the operation confirmation signal (c) from the controlled system is fed back to the transmitting master equipment 2 from the power line 1 through the receiver 4 and confirmed on a display panel, etc., provided to the transmitting master equipment 2.
