基于PLC与组态的智能粮食烘干机控制系统设计

Design of Intelligent Grain Dryer Control System Based on PLC and Configuration

中国每年由于粮食霉变而造成的损耗巨大,使用烘干机对粮食进行干燥是解决霉变的有效方法。本文以“三合一”智能控制模块作为控制核心,采用PLC和人机交互触摸屏进行自适应控制,采用自制高精度水分仪和变频烘干技术,自动匹配烘干温度,使得不同种类粮食达到最佳含水量,提高粮食质量,减少粮食损耗。

China's annual losses caused by grain mildew are enormous,and using a dryer to dry grain is an effective method to solve the problem of mildew.This paper takes the"three in one"intelligent control module as the control core,uses PLC and human-machine interactive touch screen for adaptive control,uses self-made high-precision moisture meter and variable frequency drying technology,automatically matches the drying temperature,making different types of grains achieve the best moisture content,improving grain quality,and reducing grain loss.
