摘要
介绍了基于ARM7和模糊控制算法开发的温室花卉智能灌溉系统。软件设计中移植了μC/OS-Ⅱ操作系统,采用多任务程序设计方法设计,大大降低了编写程序的复杂度。针对灌溉过程中营养液混合系统的时变性、延时性、随机性等特点,提出采用模糊逻辑控制技术来实现系统的控制。在一定程度上解决了传统控制方法不易得到系统数学模型,难于对控制系统进行有效控制的不足。实践表明系统设计可靠,能够达到良好的控制效果。
This paper introduces intelligent irrigation system for greenhouse flowers based on ARM7 and fuzzy control method. In the design of software, grafting of operation system of μC/OS-Ⅱ and adopting multitask program design method reduces the complexity of programming. Aiming at the peculiarities of time-varying, time-lagging and randomness of the nutrient admixture system, fuzzy logical control technology is used to control the system. To a certain extent, it has remedied the deficiency of the traditional control system that hardly mathematical modeling and effective controlling. It is proved that this system has reliable design and high efficiency of control.
