基于 PLC 的粮仓通风控制系统设计摘 要我国粮食产量居世界前列粮食储存显得尤为重要。储存方法不得当，会造成发霉、变质等严重损失，由于各神粮食对温度湿度的要求不同，准确控制湿度和温度尤为重要控制，为此本文设计了粮库自动通风系统，能够实时监测粮库的温湿度，并能实时监测粮库的温度和湿度，对粮食的存储起到了非常大的作用。本设计采纳 PT100 温度传感器以及 QFA3160 室内湿度传感器进行采集温湿度数据，监测部分采纳组态 MCGS 进行监测，当粮仓储粮温湿度超过一定范围时，可实现通风操作。关键词：PLC；温度传感器；湿度传感器；组态监控AbstractIt is particularly important for China's grain production to be in the forefront of the world. Improper storage methods will cause serious losses such as mildew and deterioration. Due to the different requirements of temperature and humidity, accurate control of humidity and temperature is particularly important. Therefore, the automatic ventilation system of grain depot is designed in this paper, which can monitor the temperature and humidity of grain depot in real time, and monitor the temperature and humidity of grain depot in real time, which plays a very important role in grain storage.In this design, PT100 temperature sensor and qfa3160 indoor humidity sensor are used to collect temperature and humidity data. Configuration MCGS is used to monitor the monitoring part. When the temperature and humidity of grain storage in the granary exceeds a certain range, ventilation operation can be realized.Key words: PLC; temperature sensor; humidity sensor; configuration monitoring 目 录摘 要...............................................................................................................................IAbstract........................................................................................................................II第 1 章 绪论..................................................
