Abstract [资料来源：http://think58.com] 

On the basis of analyzing the development and characteristic of automatic system of water supply, combined with status in quo of the waterworks in our country, this paper designs a suit of computer controlling system based on variable frequency speed-regulating technology. Through using computer technology, variable frequency speed-regulating technology and automation technology, the system can make the water pressure of water supply system constantly by the way of parameters self-tuning. It assuredly makes the water supply system work on all cylinders. [版权所有：http://think58.com]

This article has in detail analyzed and researched the principle of economical electrical energy of the main circuit of this systerm with the newest frequency invertor,Operated on this main circuit ,this article has designed the control-circuit,then have realized that frequency invertor can supply water for people in constant pressure with the MCU programme and PID controller in th frequency invertor.In order to pump water for the people under the uncommon condition of the frequency invertor ,this systerm has designed manual-controller.

Key Word： Water supply system   frequency invertor    economical electrical energy   MCU
