Abstract

PURPOSE:To exactly perform a control in the same transmission line and the same frequency band, by intermittently transmitting a control signal from the control side, and intermittently transmitting a receiving confirmation signal in response to the control signal, to the control side from the controlled side, in case of a remote cotrol by radio or wire. CONSTITUTION:A remote control system is constituted by coupling by radio or wire the control side and the controlled side which are equipped with a transmitting signal amplifier 46, a receiving signal high frequency amplifier 48 and a transmitting and receiving signal changeover control circuit 49, respectively. To the control side of this system is relayed a conrol pulse from the pulse generating circuit 12, the pulse signal is stored temporarily, it is compared with a confirmation signal which is sent from the cotrolled side, a temporary memory circuit 41 which controls a transmitting and receiving changeover gate conrol circuit 42 is provided, and a control signal is transmitted intermittently to the controlled side. Moreover, in the controlled side is provided a mechanism which transmits a receiving confirmation signal to the control side when the aforesaid intermitted control signal is being intermitted, and confirmation of control in the same transmission line and the same frequency band can be carried out exactly by monitoring the above confirmation signal by the monitor device 50 of the control side.
