Abstract
Disclosed are a remote control equipment and a control method thereof, whereby whereby load devices can be remotely controlled selectively through transmission and reception of a specific frequency signal using power and dedicated lines. The remote control equipment includes transmitting and receiving ends 30 and 40. The transmitting end 30 includes a line filter 20, a power supply section 31, an oscillator/amplifier 32, a frequency 34, a remote control keyboard 36, a remote control signal controller 37, a telephone signal controller 38, a synchronous frequency-transmitter 35, and a light emitting section 33 including an LED. The receiving end 40 includes a synchronous frequency-detector.4 1, a signal latch section 42, a reverse signal converter, an optical transmitter, a relay driver 43, a detector 47, and a light emitting section 46 including an LED. Information on the state of a load obtained by detecting a current in the load is reverse-transmitted to the transmitter to be displayed by the LED. Thereby, the operating state of the load and the transmission and reception states for the operation of the device can be confirmed also at a transmitter located in a different place. This also enables a conventional remote controller to control electronic products located in a different place, out of the controllable range of the remote controller.
