基于PLC和组态技术现代农业温室控制系统设计

Design of the Modern Agriculture Greenhouse Based on PLC and Configuration Technology

泰州作为江苏省农业大市,在2012年提出5年内实现"现代化农业发展走在全省前列",打造产品特色,质量和产量上有所突破。对于现代化农业,温室控制技术是关键。传统农业温室控制是根据农民种植经验,人工调节温度、湿度和二氧化碳浓度等影响农作物生长的参数,存在反应时间慢、浪费资源和产量低下等缺点。利用PLC技术、组态技术以及无线通信技术,实现PLC、组态触摸屏和GSM报警器的通讯,实时显示当前参数,自动执行机构动作,远程发送故障报警信息,从而减轻农民负担,提高农作物生长的质量和产量。系统应用于泰州草莓生产基地,相比以往种植,草莓不仅在口味上有所改善,而且产量提高30%。试验结果证明,系统稳定可靠,界面操作方便,具有很好的推广价值。

Taizhou as an agricultural big city of Jiangsu province, proposed in 2012 in five years to achieve modernization of the agricultural development to go in complete province front row, to create the product features, quality and yield breakthrough. For the modernization of agriculture, greenhouse control technology is the key, traditional agriculture greenhouse control is based on the farmers planting experience, artificial regulation of temperature, humidity and the con- centration of carbon dioxide for crop growth parameters, reaction time is slow, resource waste, low yield. Using PLC technology, configuration technology and wireless communication technology, PLC, configuration of touch screen and GSM alarm communication, real-time display the current parameters, automatic action of the actuator, a remote trans- mission fault alarm information, so as to reduce farmer burden, raise crop growth quality and yield. In the system used in Taizhou strawberry production base, compared to previous plant, not only in the taste of strawberry, were improved, and quality rises 30% , the experimental results show that, the system is stable and reliable, the interface easy to operate, and good popularization value.
