摘　　要：根据泵变频控制节能的基本原理,给出了采用AT89C51单片机进行变频调速控制而设计的变频调速恒压供水系统的控制原理及构成该控制系统的硬件结构与实现该系统控制的软件流程.这一以单片机为核心的变频调速恒压供水系统,可根据管网用水量的变化实现泵组的自动切换或变频调速,控制方便、灵活,可以大幅度地节能.According to the principle of energy-saving of pumps with frequency conversion control, the control principle of constant-pressure water supply system with frequency conversion speed regulation designed with monolithic computer AT89C51, the hardware configuration of this control system, and the flowchart of software for implementation of system control were given. Taking the monolithic computer as its kernel, this constant-pressure water supply system with frequency conversion speed regulation could be used for automatic switching and speed regulation of pump set in accordance with the flow variation in the pipeline, so that not only the control was made convenient and flexible but, more importantly, the energysaving could be realized to a great extent.
