基于PLC的烘干温度控制系统

The drying temperature control system based on the PLC

文中详细介绍了一种以PLC为核心的烘干温度控制系统,阐述了烘干温度控制的工艺流程,详细介绍了温度控制的原理和组成。PLC作为核心控制单元,通过PID算法算出加热器温度设定值与温度传感器之间的偏差,不断地对加热温度进行调整,最后使加热温度达到平衡,从而实现温度的自动控制的目的。文中介绍的这种烘干温度控制系统达到了理想的温控效果。

This article introduces in detail a kind of PLC being the core of the drying temperature control system,expounds the drying temperature control process、the principle of temperature control and composition.Being the key control unit,PLC can calculate the deviation between the set value of the heater and the sensor through PID algorithm,constantly adjust the temperature heater temperature,finally make the heating temperature balance,so as to achieve the purpose of automatic control of temperature.This system can achieve the ideal temperature control effect.
