基于PLC的煤矿副井操车控制系统的设计

Design of Auxiliary Shaft Car Operating Control System Based on PLC

针对基于单片机或集成电路的煤矿操车控制系统存在使用繁琐、维护不便、易发生误动作等缺点,提出了一种基于PLC的煤矿副井操车控制系统设计方案,介绍了该系统的结构、控制方案、控制过程以及核心闭锁关系。该系统井口和井底操作台内分别安装一套操车PLC设备,利用PLC接收井口或井底操车设备的位置信号和车房的控制信号,以控制操车设备的运行。实际运行结果表明,该系统性能稳定可靠,保障了煤矿的安全生产。

In view of shortcomings of complicated operating, inconvenient maintenance and incidental misoperation existed in mine auxiliary car operating control system based on single-chip microcomputer or integrated circuit, a design scheme of mine auxiliary shaft car operating control system based on PLC was proposed. Structure, control method, control process and core interlock relationships of the system were introduced. Wellhead and downhole work station of the system were separately installed a set of car operating PLC, and they use PLC to receive position signals and garage control signals to control running of car operating equipments. The practical operation showed that the performance of the system is stable and reliable, which ensures safety production of coal mine.
