PLC用于温度控制中数字滤波及非线性补偿处理

WITH PLC TO GET DIGETAL - FILTERING AND NONLINEAR COMPENSATION OF TEMPERATURE-THERMO- EMF

以ＦＸ２小型机为工具，介绍当ＰＬＣ用于温度测量与调节系统时，如何通过编程实现对温度采样值的数字滤波及对热电偶热电势作非线性补偿．

This paper introduces a method,when a FX2- PLC is applied to the tempera ture measure and regulate system, by making a program,the user can get the digital -filter ing of the temperature sampling value,and the nonlinear compensation of the thermocuple and thermo - emf.
