【正文】 onsumed in the water supply to the frequent changes in the pumps stopped. This not only makes the electrical work in inefficient zones, cut short the useful life of electrical and electrical equipment for the frequent failure to stop the high rate, leading to serious waste of water resources, system maintenance, repairs larger workload. With high living water and industrial water gradually increased, the traditional control methods that are outdated. Originally used for artificial water level control, water level due to the lack of accurate positioning hour monitoring, it is difficult to accurately control the pumps have stopped。 Using buoys or mechanical control devices such as water supply situation has made some changes, but because of mechanical failure more devices, poor reliability to maintenance will face great trouble. Frequency conversion technology, with its superiority in the area of energy efficiency and Hengya pressure control system can be solved by the existence of the above problems. Consider selecting Chanpianji or Plc and transducer bination at the core of the system can achieve a better control results. But in software design, Plc programming of more than Shanpianji concise, and visual。 From the hardware interface considerations, Shanpianji circuit slightly plex。 From the economic considerations, the Plc processes are mature, cost and small Plc Shanpianji a little, because the system parameters to be adjusted in accordance with the situation on the ground, Plc software, the time parameters adjustments simpler, so more conducive to aftersale personnel. For the above reasons, the selection of the Omron Plc CPM1 series with the transducer as ABB control core, coupled with PSW7 conditioners and WSP300 Biansongqi pressure, the effect was very good control, software design simple hardware interface simple and feasible, reliable, the entire system Xingjiebi very high. Transducer in the water system in conjunction with the introduction of small Plc technology not only change the traditional use of water control valves, and in energy conservation, Hengya control, are very good results, the paper introduced a transducer PLC control technology in the pump control applications. Control system using one Taiwan transducer can bring three pumps, pumps can work at the frequency pump in the conventional model can work in the frequency conversion pump model. At the pump only in frequency conversion or one of the working frequency mode through two relays efficient ensure its security and reliability. System structure as figure 1 shows, the use of placement in the li
