為實現(xiàn)水泵運行節(jié)能和有消防保障的恒壓供水，分析了水泵調(diào)速系統(tǒng)原理。以單片機模糊控制器、變頻器和3臺主泵為核心，設(shè)計出供水控制系統(tǒng)結(jié)構(gòu)，同時介紹了調(diào)試中的關(guān)鍵經(jīng)驗。該系統(tǒng)節(jié)能效果明顯，設(shè)計思路和接口技術(shù)可為同類供水系統(tǒng)的技改提供借鑒。

In order to save energy in operation of pumps and ensure water supply with constant pressure and use for fire control, the principle of saving energy of pump in variable frequency variable speed drive system was analyzed. The system structure was designed with fuzzy controller, variable frequency variable speed drive system and three main pumps as core. Some debugging experiences were introduced. This system are obvious effect in saving energy and its idea for design, interface technique may be used for reference for technique reform in analogy water supply system..
