摘要
针对选矿厂水源地水井泵站位置偏远,难于监控管理的问题,应用RTU、无线数传电台、PLC及组态监控软件组成一套远程分散控制系统。系统通过采用RS-485总线和Modbus-RTU通信协议,实现了对选矿厂水源地水井泵站生产供水系统的远程监测和控制。
For the problem of monitoring and managing the remote water supply station in a concentrator, a remote distributed control system which consists of RTU, digital radio, PLC and configuration monitoring software is designed. By the application of RS-485 bus and Modbus-RTU protocol, the control system implements the monitoring and control of the water supply systems of the concentrator.
