摘要
木薯酒精发酵过程是一个时变、非线形和多参数影响的动态过程。对发酵过程的关键参数如pH值、溶解氧的测控是非常重要的。设计了由工控机和西门子公司的PLC构成的发酵过程两级计算机集散系统,实现对酒精发酵过程中关键参数pH值、溶解氧等的数据采集与监视,同时利用该系统实现对采集到的数据进行分析与处理,从而达到最终的控制目的。
Cassava Alcohol Fermentation Process is a non-linear,time-varying dynamic process with infection by many parameter.Simultaneity,it＇s very important to measure and control pivotal parameter such as pH and DO （Dissolved Oxygen）.This paper designs the DCS（Distributing Control System） which is made by industry PC and SIEMENS PLC.This system can achieve to collection and stakeout the pivotal parameter like pH and DO in alcohol fermentation.At the same time,using the system implementation of the dissolved oxygen data collected for analysis and treatment,So as to achieve the ultimate control purposes.
