Remote control circuit for fully mechanized coal mining face equipment

The utility model discloses a remote control circuit for fully mechanized coal mining face equipment, which comprises an auxiliary module, a 42V pilot control module and an external input control loop, and the power output end of the auxiliary module is connected with the power input end of the 42V pilot control module. The signal output end of the 42V pilot control module is connected with the signal input end of an external input control loop, the circuit increases the pilot loop starting current of the high-power switch, reliable operation of a control system is guaranteed, the 42V pilot module provides double-loop independent pilot, and the control system is stable in operation. The pilot control circuit is matched with a control line and a remote diode for use to realize pilot control and pilot control line fault protection functions, monitors pilot line faults, and finds open circuit and short circuit of a circuit and whether a pilot diode is reversely connected or not in the first time, so that reliabl
