摘要
为适应采煤机远程控制方式发展的需求,设计了一种基于DP/LIN总线的采煤机控制键盘。该键盘由LIN总线数据采集模块采集控制信息,将不同按键对应的控制信息通过LIN总线进行传输,并转换为DP总线信号与PLC主机进行数据交换,进而由PLC主机控制采煤机的开停、升降、牵引,从而实现对采煤机的远程实时控制,提高了煤矿开采的自动化水平。
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.
