摘要
根据热电厂及其子换热站的实际情况，本文设计了基于3G和GPRS模块进行远程监控的自动控制系统。远程监控的子换热站采集一次供、回水压力值，通过GPRS-3G点对点通信传送到厂内监控中心，监控中心采用PID调节控制压力反馈，以实现对供热管网系统的整体控制。经过长期的运行结果表明，该系统安全性高、稳定行性好、精度高、控制反应迅速，大大提高了厂内监控系统运行的实时性、灵活性和可靠性。
According to the reality of the thermal power plant and its sub-heat exchanger station, we design Pipeline Network Remote Monitoring System based on 3G-GPRS Communication. The fully control over the heating pipe network system can be achieved by which the supply and return water values collected by the sub-heat exchanger station of the remote station was sent to the monitor center, in which PID will be employed to adjust the control pressure feedback, by means of the point-to-point communication of GPRS-3G The long-term operating results show that the system can significantly improve the operation of plant monitor system on the real-time, flexibility and reliability dependent on its advantages such as safety, stability, accuracy and rapidity.
