    Apparatus for the remote control of an electrical load by means of duplex carrier frequency transmission along a length of power line supplying power to said load comprises first transmission and receiving circuits coupled to the length of power line at or towards one end thereof and a second transmission and receiving circuit coupled to the length of power line at or towards the other end thereof, the first transmission circuit being operative to transmit control signals to the second receiver circuit along the length of power line at a first carrier frequency, and the second transmitter circuit being operative to transmit control signals to the first receiver circuit along the length of power line at a second carrier frequency, wherein the power supply to the load along the length of power line is only maintained while coded signals from the first transmitter circuit are successfully identified by the control receiver circuit and coded control signals from the second transmitter are successfully identified by the first receiver circuit. <IMAGE>

    The invention relates to telemechanics and can be used in a ruling industry.
    The purpose of the invention is to increase the safety of mining operations by monitoring the health of the alarm.
    The drawing shows a diagram of the device.
    The device for remote control contains electric motors 1 and 2, power circuit 3, switches 4 and 5, switching unit 6, separation unit 7, transmitter 8, receiver 9, encoder 10, decoder 11, separation unit 12,
    receiver 13, transmitter 14, Managed encoder 15, receiver 16, control panel 17, matching element 18, battery 19, alarm health monitoring unit 20, alarm unit 21.
    The device works as follows.
    The operator presses the On button on the control panel 17, resulting in a turn-on signal. The command signal comes from the output of the control console 17 to the controllable encoder 15, in which the On command. is being prepared for the transmitter

    14, to further transmit the command signal through the line. At the same time, the signal also goes to the alarm control unit 20 on the one hand, and to the alarm block 21 on the other hand, the working ability of unit 2 can be monitored with this signal, i.e. if he can make a sound if necessary. If block 21 is in the operational state, the transmitter 14 sends an encoded signal in turn,
