液态配方实训教学系统的设计与实现

Practice Teaching of Liquid Formula: Design and Implementation

基于工业生产中常需要对不同的物料严格按照一定的比例进行混合.文章介绍了在现代工业生产过程中,采用可编程控制器(简称PLC)作为系统的控制核心,利用上位机设置不同的配方比例,可快速、方便地实现各种不同物料的不同比例精确混合的一种液态配方控制系统.学生利用该实训教学系统可以从系统的硬件组成、工作原理以及主、从站的设计等方面进行系统学习和实训.

Based on requirement for materials mixture percentage in current industry production, this article introduced a PLC control module with supervisory computer set-up which is widely used in modem industry field; it could fulfill the function of precise mixture percentage. Student could have practice class focusing on system hardware, working principles, main and subordinate station design.
