Zhonghua Han

Abstract

A variable frequency constant pressure water supply system based on STC12C5A60S2 MCU on the basis of further research for variable frequency constant pressure water supply system was introduced.In order to make water supply more economical and energy saving,make use of the combination MCU with frequency converter to control the operation of pump group,realize the change of export water pressure of the water supply along with the setting water pressure and equality of export water pressure of the water supply and setting water pressure.The system is high efficiency,reliable,stable and energy saving,it can be widely used in building water supply system.
