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。
In order to realize the real-time collection of crop water information and the timely irrigation of crop, a control system of crop water information collection, analysis and automatic irrigation based on WinCE and ARM was designed. On the basis of summarizing the existing problems of less system resources and less friendly man-machine interface in the automatic crop irrigation system, the hardware using ARM embedded system and WinCE has strong scalability, real-time, portability and application development Short cycle, friendly man-machine interaction and other advantages, from the hardware implementation and software development designed a new automatic irrigation system. The results show that the system can achieve better soil moisture monitoring. At the same time, by selecting the middle and lower soil moisture content to set the irrigation start and stop threshold, to achieve the purpose of saving water. The system performance is stable and reliable, which can meet the real-time collection and automatic irrigation requirements of crop water information.
