Waterplant remote control system of combining Data Transceivers and GPRS

For the system supplying water of city and town water works, it adopts a mode of combining CPM2AH PLC of OMRON company with the distributed I/O module of 4000 series of ADVANTECH company and takes two kinds wireless communication ways of Data Transceiver and GPRS as data transmission approach. The software of upper computer and hardware circuit of wireless remote control system of water works were emphatically designed. The scheme of negative pressure waverate of flow follows diagnosing feed pipe net leakage had been studied. The system has realized the well group water pump controlling and the pipe net relevance parameter acquisition and transmission such as rate of flow and pressure. Those have provided a guarantee to safe and stable operation of the supplying water system.
