CAN总线在技术改造中的应用——以四辊压延机温控系统的技术改造为例

Initial study on application of CAN bus in technical innovation——taking technical innovation of controlling temperature system as an example

以四辊压延机的温度控制系统的技术改造为例,指出了该设备在技术改造中应注意的三个方面及解决方案:①现场总线的选用采用C A N总线;②温度系统模型的简化和热力学方程的建立;③控制算法采用TunningPID-D ahlin复合控制算法.它为银川市老企业中的设备改造提供一些有益的借鉴.

This paper took technical innovation of 4 Roll calender's controlling temperature system as an example,pointed out the main problems and put forward the following solutions. ①Selection of CAN bus;②Simplification of temperature's model and building of thermodynamic equation; ③Selection of Fuzzy Tunning PID Dahlin controlling method. It provided reference for technical innovation of old enterprises in Yinchuan.
