Abstract
Remote control equipment and a control method thereof, 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. The transmitting end includes a line filter, a power supply section, an oscillator/amplifier, a frequency, a remote control keyboard, a remote control signal controller, a telephone signal controller, a synchronous frequency-transmitter, and a light emitting section including an LED. The receiving end includes a synchronous frequency-detector, a signal latch section, a reverse signal converter, an optical transmitter, a relay driver, a detector, and a light emitting section 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.
