Abstract: In order to adapt to needs of development of remote control method of shearer, a control keyboard of shearer based on DP/LIN bus was designed. The keyboard collects control information via the LIN bus data acquisition module, and can transmit control information of corresponding different keyboard through the LIN bus, and convert the control information to DP bus signal, so as to exchange data with PLC, and control open/stop, lift and traction of shearer by the PLC. The control keyboard can realize remote real-time control of shearer, and improve automation level of coal mining.
