PLC集中控制系统在煤矿胶带输送机上的应用

Application of PLC Centralized Control System of Coal Mine Belt Conveyor

针对某矿胶带运输系统线路长、岗位多、联络环节多的特点,提出了一种采用PLC集中控制系统控制煤矿胶带输送机的方案,介绍了PLC集中控制系统的构成、工作原理和系统功能。该系统通过集中控制和工业电视相结合,对井下主煤流强力胶带输送机和振动给煤机及煤仓煤位计等相关设施进行监测,实现了主煤流系统的集中控制。实际应用表明,该系统运行良好,实现了胶带输送机的安全高效运行。

In view of characteristics of long lines, multi posts and multi links of transport system of belt converyor of a mine, the paper proposed a scheme which adopts PLC centralized control system to control coal mine belt conveyor. It introduced composition, working principle and functions of PLC centralized control system. The system combines industrial television with centralized control to monitor related devices such as underground powerful belt conveyor, vibration coal feeder and coal level sensor of coal hunker, which realizes centralized control of main coal flow system. The practical application showed that the system runs well, and achieves safe and efficient running of conveyor belt.
