基于ARM处理器的灌溉自动控制系统设计

为了实现农作物需水信息的实时采集和农作物的及时灌溉,设计了基于WinCE和ARM的作物需水信息的采集、分析与自动灌溉控制系统。在总结原有的农作物自动灌溉系统存在的系统资源较少、人机交互界面不够友好等不足的基础上,利用ARM嵌入式系统和WinCE的硬件扩展能力强、实时、移植性好、应用程序开发周期短、人机交互友好等优势,从硬件实施和软件开发两个方面设计了一种新的自动灌溉系统。实测结果表明,该系统可以较好地实现土壤含水率的监测。同时,通过选择中、下层土壤含水率来设定灌溉起、停阈值,达到了节水的目的。系统性能稳定、可靠,能够满足农作物需水信息的实时采集和自动灌溉要求。

Automatic Irrigation Control System Design Based on ARM Processor

In order to realize the crops of real time data collection and water demand information,designing the timely irrigation crops based on WinCE and ARM crop water demand information collection,analysis and automatic irrigation control system.At the conclusion of the original crop automatic irrigation systems existing system fewer resources,man-machine interface enough on the basis of the drawbacks of friendly,based on the ARM embedded systems and WinCE hardware expansion ability strong,real-time,portability,application development cycle is short,the advantage of human-computer interaction friendly from hardware implementation and software development two aspects designs a new kind of automatic irrigation systems.Using this system conducted on-site,testing results have shown that the system can better realize the soil moisture monitoring.Meanwhile,through the choice of soil moisture content,middle-stratum set to irrigation up,stop threshold,good reached water-saving effect,stable performance,reliable,and can satisfy the requirement of real-time information collected crops and automatic irrigation.
