【摘要】：針對農(nóng)田環(huán)境信息采集過程中監(jiān)測周期長、環(huán)境干擾大等特點(diǎn),設(shè)計了一種基于混合天線無線傳感器網(wǎng)絡(luò)稻田環(huán)境信息實(shí)時監(jiān)測系統(tǒng),采用分簇路由協(xié)議進(jìn)行組網(wǎng),為不同類型的節(jié)點(diǎn)配置不同類型的天線,并使用轉(zhuǎn)臺控制匯聚節(jié)點(diǎn)定向天線的方向,以擴(kuò)大網(wǎng)絡(luò)的覆蓋范圍和提高系統(tǒng)的穩(wěn)定性�；谠撓到y(tǒng)進(jìn)行長時間稻田組網(wǎng)試驗(yàn),對網(wǎng)絡(luò)丟包率和稻田環(huán)境參數(shù)采集準(zhǔn)確性進(jìn)行測試,試驗(yàn)結(jié)果表明,系統(tǒng)運(yùn)行穩(wěn)定、測量準(zhǔn)確,網(wǎng)絡(luò)數(shù)據(jù)平均丟包率為0.44%,稻田空氣溫度、空氣相對濕度和土壤含水率的平均相對誤差分別為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.
