摘要：为解决无人值守泵站故障处理不及时这一难题，结合ModbusRTU 变频器网络技术，采用全球移动通信系统（GSM)无线网络，设计了无人值守的变频恒压供水控制系统，实现了对供水机组的无线实时监控。实践证明，该系统实现了泵房无人值守，且运行稳定、使用经济，具有广阔的推广应用前景。

Abstract: For solving the problem of promptly processing in automatic pumping station, the automatic constant pressure with changing frequency water supply control system was designed, which was combined with  Modbus-RTU inverters network technology and GSM wireless network. The wireless, real-time monitoring to the water supply unit was achived. The practical application shows that the system works stably, has reasonable cost , and realizes the unmanned control of pump room. It illustrates a good prospect of application and extension.
