摘要
多泵站远程监控系统是基于PLC控制和GPRS传输的分布式远程泵站控制系统,在站点分布广泛、通讯稳定性要求高的条件下得到了很好的应用。文中介绍了多泵站远程监控系统的功能与构成,分别阐述了现场控制部分、无线传输链路和监控中心的结构与工作方式以及PLC在现场控制和数据通信中的作用,并分析了监控系统的使用效果。
The multi pumping station remote monitoring system is a kind of distributed remote pumping station control system based on PLC and GPRS transmission. It has got very good applications under the conditions of widely distributed sites and highly communication stability requirement. This paper introduces function and structure of the system, and presents the struc ture and working style of the field control section, the wireless transmission link and the monitoring center. Also the role of PLC in on-site control and data communications is discussed. At last, the paper analyzes the application effect of monitoring and control system.
