基于物联网的节水灌溉自控系统研究

摘要

为提高农田灌溉用水利用率、降低灌溉用水成本,提出一种基于无线传感器网络和Internet技术的农田自动灌溉控制方法。重点分析了传感器网络节点路由协议,实现了系统硬件与软件设计,将各种传感器构成智能化传感器网络,从而全面提升了系统的自动化与监测水平。最后分析了该网络在Internet基础上实现某农厂的农田节水灌溉自控系统的实现方法,用户使用手机或无线PDA就可以方便地进行土壤含水量的在线监测与控制,实现了灌溉自动化。应用结果表明,系统通过嵌入式控制技术完成智能化灌溉,有助于改善农业灌溉用水的利用率和灌溉系统的自动化水平普遍较低的现状,可很好地实现节水。%To improve irrigation water use efficiency and reduce cost of irrigation water,this paper discussed the design of wireless sensor network and Internet technology of farmland automatic irrigation control method.Emphasis on An analysis of the routing protocol of sensor network nodes is emphasised to achieve the system hardware and software design,it will constitute a variety of sensors intelligent sensor network to enhance the overall automation system and monitoring levels.The final analysis of the network in the Internet based on the agricultural plants of farmland water-saving irrigation system integrated approach.Users use mobile phones or wireless PDA can easily soil moisture content of online monitoring and control to realize the irrigation automation.Application results show that system through the embedded control technology complete intelligent irrigation,improve the agricultural irrigation water use efficiency and irrigation system automatization is generally low status,can well realize water saving.
