摘　　要：介绍了一种用变频器和单片机组成的恒压供水系统的设计方案,给出了控制器的硬件结构及控制原理框图。该系统根据供水管网用水量的变化和相应的压力,调节水泵投入台数及转速,实现全自动恒压供水,达到了高效节能的目的。A new kind of constant pressure water-supply system composed of a single-chip computer and frequency changer is introduced. The hardware structure and control principles of this system are presented. This system can regulate the amount of water pumps and their rotational speeds according to the changes of the amount and pressure of the water flow in the water-supply net, a total automatic water-supply system pressure is thus realized, and high efficiency and energy saving are obtained.
