    摘要:

    為解決果園環(huán)境參數(shù)遠(yuǎn)程檢測(cè)中網(wǎng)關(guān)節(jié)點(diǎn)因電磁干擾造成ZigBee模塊傳輸距離過短,不能滿足動(dòng)態(tài)配置ZigBee網(wǎng)絡(luò)的不足,,采用核心板加底板及模塊化接口的硬件設(shè)計(jì)思路,,提高系統(tǒng)的抗電磁干擾能力;采用串口編程及單線程通信策略實(shí)現(xiàn)ZigBee網(wǎng)絡(luò)動(dòng)態(tài)配置,,用判斷2次接收數(shù)據(jù)差值及變化趨勢(shì)決定是否傳輸數(shù)據(jù)以減小功耗,。測(cè)試表明,網(wǎng)關(guān)節(jié)點(diǎn)可穩(wěn)定采集數(shù)據(jù)并遠(yuǎn)程傳輸,,提高了抗電磁干擾能力,與電路板集成設(shè)計(jì)相比通信距離增加了1倍,,并可靈活地動(dòng)態(tài)配置

    Abstract:

    ZigBee網(wǎng)絡(luò)。In the remote detection of orchard environmental parameters, gateway nodes suffer from two deficiencies that remain to be solved: short transmission distance of ZigBee module due to electromagnetic interference; failure to meet the dynamic configuration of ZigBee network. The hardware design adopted the structure of kernel board plus motherboard and modularized interface to improve antielectromagnetic interference performance. The software design adopted two strategies, i.e. serial programming and single thread communication, to realize dynamic configuration of ZigBee network. To reduce energy consumption of the system, gateway nodes decided whether to upload data according to the difference between consecutivelyreceived data and the variation tendency. The test results indicated that gateway nodes could realize stable data acquisition and remote data transmission. Due to the improvement of antielectromagnetic interference performance, communication distance was doubled compared with the design of integrated circuits board. Moreover, the ZigBee network could be configured flexibly and dynamically.
