【摘要】：通常傳感器節(jié)點(diǎn)需要分布在外界環(huán)境中進(jìn)行數(shù)據(jù)采集和傳輸,且采用電池進(jìn)行供電,因此必須降低傳感器節(jié)點(diǎn)的能耗。ZigBee技術(shù)由于其低成本、低功耗、低數(shù)據(jù)速率等特點(diǎn)成為當(dāng)前應(yīng)用最為廣泛的無線傳感器網(wǎng)絡(luò)通信技術(shù)。本文通過設(shè)計和實現(xiàn)基于ZigBee的無線傳感器網(wǎng)絡(luò)數(shù)據(jù)采集系統(tǒng),了解ZigBee的協(xié)議體系結(jié)構(gòu),深入研究AODVjr路由算法、Cluster-Tree路由算法和ZigBee路由算法。具體的研究內(nèi)容如下:(1)介紹ZigBee協(xié)議的體系結(jié)構(gòu),分析ZigBee網(wǎng)絡(luò)中的節(jié)點(diǎn)設(shè)備類型和ZigBee網(wǎng)絡(luò)的拓?fù)浣Y(jié)構(gòu),確立ZigBee網(wǎng)絡(luò)的路由策略,為研究ZigBee技術(shù)中的路由算法做準(zhǔn)備。(2)介紹ZigBee網(wǎng)絡(luò)的組建過程,然后研究AODVjr路由算法和Cluster-Tree路由算法,并結(jié)合AODVjr路由算法中選取最佳路徑的優(yōu)勢和Cluster-Tree路由算法通過父子節(jié)點(diǎn)轉(zhuǎn)發(fā)數(shù)據(jù)包的便捷來研究ZigBee路由算法。最后對ZigBee路由算法在一定程度上減少ZigBee網(wǎng)絡(luò)中端到端的時延,均衡網(wǎng)絡(luò)中傳感器節(jié)點(diǎn)的能量兩個方面提出相應(yīng)的改進(jìn)方法,并通過NS-2仿真軟件證明其正確性和有效性。(3)確定待測區(qū)域內(nèi)需要采集的環(huán)境參數(shù),對ZigBee網(wǎng)絡(luò)中的ZigBee終端節(jié)點(diǎn)、ZigBee路由節(jié)點(diǎn)、ZigBee協(xié)調(diào)器節(jié)點(diǎn)進(jìn)行設(shè)計。編寫上位機(jī)中的環(huán)境數(shù)據(jù)實時顯示軟件,對ZigBee無線傳感器網(wǎng)絡(luò)采集到的溫度、濕度、光照強(qiáng)度信息進(jìn)行存儲并以參數(shù)和曲線兩種形式展現(xiàn)給技術(shù)人員。
[Abstract]:In general, sensor nodes need to be distributed in the external environment for data acquisition and transmission, and batteries are used for power supply. Therefore, the energy consumption of sensor nodes. ZigBee technology must be reduced because of its low cost and low power consumption. Low data rate has become the most widely used wireless sensor network communication technology. In this paper, we design and implement the data acquisition system of wireless sensor network based on ZigBee, understand the protocol architecture of ZigBee, and deeply study the AODVjr routing algorithm Cluster-Tree routing algorithm and ZigBee routing algorithm. The specific research contents are as follows: (1) introduce the architecture of ZigBee protocol, analyze the type of node equipment in ZigBee network and the topology structure of ZigBee network, and establish the routing strategy of ZigBee network. In order to study the routing algorithm in ZigBee technology, this paper introduces the construction process of ZigBee network, and then studies the AODVjr routing algorithm and Cluster-Tree routing algorithm. Combining the advantages of selecting the best path in the AODVjr routing algorithm and the convenience of forwarding packets by the parent and child nodes, the ZigBee routing algorithm is studied in this paper. Finally, an improved ZigBee routing algorithm is proposed to reduce end-to-end delay and equalize the energy of sensor nodes in ZigBee networks to a certain extent. The correctness and validity of the method are proved by NS-2 simulation software. The environmental parameters to be collected in the area under test are determined. The ZigBee terminal node ZigBee routing node and the ZigBee coordinator node in ZigBee network are designed. The real-time display software of environment data in the upper computer is written to store the temperature, humidity and light intensity information collected by ZigBee wireless sensor network and show them to technicians in the form of parameters and curves.
