【摘要】：针对农田环境信息采集过程中监测周期长、环境干扰大等特点,设计了一种基于混合天线无线传感器网络稻田环境信息实时监测系统,采用分簇路由协议进行组网,为不同类型的节点配置不同类型的天线,并使用转台控制汇聚节点定向天线的方向,以扩大网络的覆盖范围和提高系统的稳定性。基于该系统进行长时间稻田组网试验,对网络丢包率和稻田环境参数采集准确性进行测试,试验结果表明,系统运行稳定、测量准确,网络数据平均丢包率为0.44%,稻田空气温度、空气相对湿度和土壤含水率的平均相对误差分别为0.26%、0.64%和0.33%。
[Abstract]:In view of the characteristics of long monitoring period and great environmental interference in the process of farmland environmental information collection, a real-time monitoring system for paddy field environment information based on hybrid antenna wireless sensor network is designed, and the cluster routing protocol is used to build the network.Different types of antennas are configured for different types of nodes and the turntable is used to control the direction of the directional antenna of the convergent node in order to expand the coverage of the network and improve the stability of the system.Based on the system, the net loss rate of the network and the collection accuracy of the environmental parameters of the paddy field are tested. The results show that the system runs stably, the measurement is accurate, the average packet loss rate of the network data is 0.44 and the air temperature of the paddy field is 0.44.The average relative errors of air relative humidity and soil moisture content were 0.260.64% and 0.33%, respectively.
