基于S7-1200 PLC与触摸屏的西瓜温室大棚智能控制
|
摘要
随着科技的日益发展,农业现代化的不断普及,温室大棚的使用也越来越广。为了提高农产品的生产与利益的最大化,需要对温室大棚实现智能化的生产与监控。该文采用西门子S7-1200 PLC和触摸屏来控制与监控西瓜温室大棚,实现A/D、D/A之间的转化与控制,以及运用PID精准调节温度和光照强度等生产参数,触摸屏作为上位机,实现人机界面交换的功能,可以对环境变量进行监控、调节、报警提示等。这种基于PLC和触摸屏的控制系统,可以实现农业中温室大棚的智能化生产,能够提高农产品的数量和质量,同时出现故障易于检修,整个生产过程也易于监控与调节。
With the development of science and technology,the popularization of agricultural modernization,the use of greenhouses is becoming more and more extensive. In order to improve the production and benefit of agricultural products,it is necessary to realize intelligent production and monitoring of greenhouses. This paper uses Siemens S7-1200 PLC and touch screen to control and monitor the greenhouse,PLC-1200 as the lower machine,realize the conversion and control between A/D and D/A,and use PID to accurately adjust the temperature and light intensity. The touch screen used as the upper machine,which realizes the function of man-machine interface exchange,can monitor,adjust,alarm the environment variables and so on. This kind of control system based on PLC and touch screen can realize the intelligent production of greenhouses in agriculture,improve the quantity and quality of agricultural products,and at the same time,it is easy to overhaul and the whole production process is easy to monitor and adjust.
