Abstract: Due to high cost and difficulty to research remote control system for shearer on actual working face, the paper proposed a design scheme of networked remote control testing system for shearer, researched internal control structure of shearer met testing requirements, and introduced design of on-board controller and wireless transceiver controller of shearer, control softwares for ground host and underground host. The system adopts a remote/local control mode to build a network of the remote control system for shearer, and transmits control signal by Ethernet, fiber, RS485 bus and wireless network, realizes remote/local control of shearer action on ground host and underground host. In addition, the testing system also provides an experimental platform for further research of remote control for shearer.
