针对传统的供水系统供水的水泵消耗了大量的电能,造成供水效率低下、耗能大、水压和部分设备不稳定、可靠性差以及设备造价高等问题,文中提出一种基于PLC、变频器及其自带PID功能、泵电机和压力传感器等组成的一套智能控制系统,该系统利用变频器自带PID功能不仅可以满足对生活供水的质量、可靠性、节能性和设备稳定性的要求,而且改善了以往利用PLC加PID扩展功能模块,造成的PID算法编程难度大、调试困难等问题,并降低了设备成本.利用压力传感器将实际水压装换成模拟信号直接传送给变频器,变频器通过自带的PID功能调节系统参数,实现无级调速,快速精确地调节水泵的转速,从而改变水压的大小,达到恒压供水的目的. PLC与变频器联合控制泵电机的启停,以及工频变频运转. 利用变频器能快速平滑地调节泵电机转速,并且启动泵电机的方式为软启动,也有效地缓解了供水过程中的"水锤效应".

The traditional water supply system for the pump consumes a lot of energy, resulting in inefficient water supply, energy consumption, water pressure and some of the equipment instability, poor reliability and higher cost of equipment problems. this paper describes a set of intelligent control system consists of PLC, inverter and its own PID function,the pump motor and pressure sensors and other components of the system using the drive comes with PID function not only meet the domestic water supply of quality,reliable, energy efficiency and device stability requirements,but also improves the previous use of PLC expansion modules plus PID, PID algorithm programming caused by difficult,difficult to debug problems,and reduced equipment costs.And the actual hydraulic pressure sensor mounted into an analog signal is transmitted directly to the drive, the drive comes with PID function by regulating the system parameters to achieve variable speed,quickly and accurately adjust the pump speed, thus changing the water pressure size,reach constant pressure water supply purposes.Combined PLC and inverter control start and stop the pump motor and frequency inverter operation.Using the drive can quickly and smoothly adjust the pump motor speed, and the way to start the pump motor soft start, but also effectively easing the supply process of"water hammer."
