基于变频器和PLC的恒压供水系统技术改造

摘要

介绍了应用变频器、PLC、压力传毫器及压力模块、数模转换模块改成的智能控制系统对供水系统进行技术改造．论述了控制系统的工作原理、硬件软传设计。通过实践证明，PLC与变频器配合控制，可以较好地实现恒压供水和节能的目标。%This article describes the frequency converter, PLC, pressure sensors arid pressure module, digital to analog conversion module into a smart control system for technological transformation of the water supply system, discusses the control system works, hardware and software design. Practice has proved that the PLC and frequency converter with control, constant pressure water supply and energy conservation goals can be better achieved.
