摘　　要：根据集中供热的实际情况,设计了换热站自动控制和GPRS远程数据传输系统。详细介绍了循环泵和补水泵的变频控制方案及具体实施,以及温度自动控制回路与通过GPRS网络进行远程数据传输的设计。运行结果表明,该系统稳定性好,调节精度高,易于控制,节能效果优。Based on the practical situation of centralized heating supply, the auto-control system and GPRS re- mote data transmitting system for the heat-exchange station were designed. The control principles and practical schemes of the frequency-variable control of cyclepump and water-refilling pump were described. Then the tempera- ture auto-control loop and GPRS transmitting data were designed. It was shown that the system was better in relia- bility, adjusting accuracy as well as saving energy.
