摘要
PLC和变频器已成为工业生产过程压力、流量、液位、速度等典型控制系统的主要控制装置。结合某乡镇"PLC+变频器"恒压供水设计应用经验,介绍使用PLC完成供水压力采集、数据标准化转换、PID控制运算、模拟量输出到最后变频器输出调节控制的具体实现办法,也可应用于其它工业控制场合。
PLC and frequency converter have become the main control devices of typical control systems such as pressure,flow,liquid level and speed in the industrial production process.Combining with the design and application experience of"PLC&Frequency Converter"constant pressure water supply in a town,this article introduces the specific realization method of using PLC to complete water supply pressure collection,data standardization conversion,PID control calculation,analog output to the final frequency converter output adjustment control,which can also be applied Other industrial control occasions.
