为提高煤矿排水效率,降低运行成本,结合新河煤矿的实际情况,在改造原有管路、完善传感器和执行机构的基础上,构建了基于西门子PLC的自动排水控制系统架构。系统采用就地和地面调度2级控制方式,编写了数据采集、显示和控制的PLC程序,实现了就地、手动、远控和自动4种控制模式。实践表明,系统运行稳定、可靠。 In order to improve the drainage efficiency of coal mine and reduce the operating cost, the automatic drainage control system architecture based on Siemens PLC was constructed based on the actual situation of Xinhe Coal Mine, based on the reconstruction of the original pipeline and improvement of sensors and actuators. The system uses two levels of control on-site and on-the-ground control and compiles a PLC program for data acquisition, display and control, and realizes four control modes: local, manual, remote control and automatic. Practice shows that the system is stable and reliable.
