新型恒压供水单片机控制系统

New type constant pressure water supply system with microprocessor control

介绍一种新型恒压变频供水自动控制系统的软硬件设计．该系统是以８９５１ 单片机及接口电路组成控制器，以供水管道压力为被控制量的闭环控制系统，适用于高层楼宇自动供水。

This paper introduces a software and hardware design for a new type constant pressure water supply system by using a single chip microprocessor controller. The frequency of power supply to the motors is controlled by the microprocessor to keep the water pressure constant. The control system consists of a 8951 single chip microprocessor and interface circuits. The pressure in the water supply pipe is the controlled variable and a closed loop system is constructed. The designed system can satisfy the automatic water supply requirement of high buildings and boilers.
