摘要
为了提高农业生产灌溉自动化程度和节约水资源,结合干旱半干旱地区土壤的特点,设计了基于PLC和GPRS的农田墒情监测和抗旱系统。系统由上位机WinCC组态软件通过GPRS无线网络和PLC通信,对土壤墒情和灌溉水泵进行远端监控,组成了区域农田墒情的监测和抗旱SCADA系统。系统结构简单,通信速度快、运行稳定,具有一定实用性和推广价值。
In order to improve the automation of agricultural irrigation and save water resources, combining with the charac-teristics of soil in arid and semi-arid areas, this paper designed a soil moisture monitoring and farmland drought system based on PLC and GPRS technology. The system can achieve remote monitoring of the soil moisture and irrigation pumps by WinCC configuration software with the help of GPRS wireless network and PLC communication, and can form a farmland soil moisture monitoring and drought-resistant SCADA system in an area. The system has a simple structure, fast communication, runs stably, has certain practicability and commercial worth.
