基于PLC的综合改善大棚种植环境系统

好的大棚环境对提高大棚蔬菜产量具有积极的指导作用．文章提出了一种自动调节大棚环境的监控系统．该套系统分别对大棚的温度、湿度、含氧量以及光照度进行检测．根据这些数据实时控制空气加湿器、空气烘干器、空调、草帘等设备,使大棚环境达到理想的状态．该套系统可以避免人为控制设备运行时间过长而导致的人力、能源等的浪费,从而达到节能的目的,同时达到理想的控制目标．整个设备都是基于PLC和触摸屏组态软件的自动控制,基本无需人为操作．

A Comprehensive Way of Improving Greenhouse Environment System Based on PLC

The output of greenhouse vegetables are firmly related to its growth environment,an automatic control greenhouse environment quality monitoring system was designed.In view of the large quantity of the greenhouse environment controlling electrical equipment,the temperature,humidity,oxygen level and illumination are measured by the system.The measured dates are then analyzed by the system to realize the real-time control of the household appliances such as humidifier,air drying machine,air conditioning and straws to make greenhouse environment comfortable.This system can greatly reduce the cost,and avoid the energy waste caused by the artificial control to achieve the energy-saving goal;the whole device is based on PLC and touch screen configuration software,automatic run without human control.
