要在工業(yè)生產(chǎn)和城市居民生活中大量使用水，供水的壓力在不同時(shí)間段不均衡以及管網(wǎng)覆蓋面積大、結(jié)構(gòu)復(fù)雜，經(jīng)常出現(xiàn)用戶用水壓力不足、維修不便和耗能高等缺點(diǎn)。在現(xiàn)有的供水監(jiān)控系統(tǒng)，基本上采用的是傳統(tǒng)的模擬儀表單回路監(jiān)控, 現(xiàn)場(chǎng)參數(shù)由人工觀測(cè)，已經(jīng)不適應(yīng)生產(chǎn)的發(fā)展。其次，多臺(tái)運(yùn)行設(shè)備實(shí)現(xiàn)網(wǎng)絡(luò)監(jiān)控與控制還可以降低供水企業(yè)的生產(chǎn)成本。為此，我們開(kāi)發(fā)一套融3C（puter, munication and

There are some shortings, for example, the pressure of water is not enough, energyconsuming is high, and so on. The reasons are that waterpressure is not balance in different time and the construction is very plicated. The present watersupply control system is traditional imitation single returncircuit system. The parametre is got by people on spot. Obviously, it does not adapt the demand of development. At present, the parametres are being more and more, watersupply equipments are being more and more plicated. The reliability must be high and the response must be fast. The quality of control system is artificial. Meanwhile, the cost of watersupply will be reduced if the automatic control system is taken i
