摘要
本文根据PID控制和模糊控制原理,提出了一种实用的开放式乳酸发酵过程自动控制系统的实现方法。该系统采用CN113型工业pH计作为前端数据采集传感器、P87C591作为核心处理器,通过RS232串行通讯把数据处理结果传送到上位机,通过人性化的上位机人机交互界面实现用户参数设置、运行状态和曲线显示。该仪器是开放式系统,可完全实现对实验室发酵过程pH值的自动控制。经现场试验,取得了满意的效果。
According to the PID control and Fuzzy control,this article introduced an applied method of an open autocontrol system for the course of lactic fermentation.It used a pH sensor as the spot detector,and took the micro controller PLC87C591 as the core pro- cessor. This system sent the spot data to the master with the serial communication, and by means of the simple man-machine interface it can set the proper parameter, and displayed the curves for the running state. This open system meets the needs of the autocontrol for the course of lactic fermentation. It has obtained the satisfactory effect after the track field test.
