Abstract

PURPOSE:To ensure an assured remote control in a wide band of transmission, by securing a wiring of the optical fiber from several control parts through the optical receiver provided at the area near the part to be controlled and then transmitting the code signal corresponding to each control part. CONSTITUTION:The optical fiber 7 is wired to the rooms R12, R13, R14, R22, R23, R31 R32 and R33 each of which requires the remote control. And when a control is given to the part 4 to be controlled from a desired room, the optical signal sent from the optical transmitter 1 is transmitted to the part 4 via the fiber 7. This optical signal is composed of the code corresponding to the relevant room, and the optical receiver 4 converts the reception signal into the code signal and then demodulates 15 the signal to obtain the code signal corresponding to the output terminal A. Thus the transistor Q2 is turned on, and the relay RY is excited to close the contact 16 along with an actuation of the load. Thus a remote control is carried out.
