基于GPRS技术的膜下滴灌自动化控制系统的设计

Automatic drip irrigation under film control system design based on GPRS technology

为进一步推广滴灌技术,有效解决现有轮灌制度人为因素影响大的问题,本文介绍了一种基于GPRS技术的灌溉自动控制系统,利用GPRS技术将监控箱采集的土壤水分、用水量等数据传输到上位机软件平台,对滴灌系统的灌溉用水量进行实时计量与监测,实现膜下滴灌的自动化控制。通过在滴灌项目的示范安装及实验证明,该系统运行稳定可靠,能够准确的采集土壤水分、用水量等信息,并进行滴灌的自动控制。与传统的灌溉方式相比,该系统结构简单、性能稳定,实现了自动化、精确化的灌溉控制,得到了用户的好评。

As a further extension of drip irrigation technology, to effectively minimize the human factors of the existing rotation irrigation, this paper introduces an automatic control system based on GPRS technology, which transfers the data of soil moisture, water consumption etc in the monitor box collection to the host computer software platform, enabling real-time water measurement and monitoring of the drip irrigation system, thus automatic irrigation control can be achieved. Through demonstration installation and test of drip irrigation project, the system is stable and reliable, and it can accurately capture the soil moisture, water consumption and other information; automatically control the irriga- tion system. Compared with the traditional irrigation method, the system has simple structure, stable performance, and precise automatic irri- gation control; therefore it won a lot praise of the customers.
