前言本文介绍的是用一套 Z—8(?)单板机控制多个生产对象、可以选用多种生产工艺曲线方案并且带有 PID—PD 调节算法软件的工业过程自动控制系统。目前国内的染色设备控制部分尚未健全。虽然对于不同织物、不同染料配方都有着不同染色工艺过程和温度曲线的理论要求;但一般都是采用蒸汽加热、冷水降温,而用手动阀门的方式控制。这种手动控制方 Preface This article describes an industrial process automation system that uses a set of Z-8 (?) Single-board machines to control multiple production objects, a wide range of production process curve options and PID-PD tuning algorithm software. At present, the dyeing equipment control part of our country has not been perfect yet. Although for different fabrics, different dye formulations have different dyeing process and temperature curve of the theoretical requirements; but are generally used steam heating, cold water cooling, but with manual valve control.
