【摘要】：水文是水利的基礎(chǔ)性工作，得到各級(jí)政府的高度重視。防洪預(yù)警是水文工作的基礎(chǔ)，做好防洪預(yù)警工作，對(duì)確保防洪安全、財(cái)產(chǎn)安全、經(jīng)濟(jì)發(fā)展等，具有極端重要的作用。我國(guó)是洪水多發(fā)國(guó)，怎么進(jìn)行有效的防洪預(yù)警工作，至關(guān)重要。隨著當(dāng)今科學(xué)技術(shù)的不斷發(fā)展，傳統(tǒng)的防洪預(yù)警技術(shù)已經(jīng)不能完全滿足人們的防洪預(yù)警期望與要求。 無(wú)線傳感器網(wǎng)絡(luò)(WSN，Wireless Sensor Networks)具有自組織、部署快速、屏蔽干擾性強(qiáng)、無(wú)需人工值守等優(yōu)點(diǎn)。將大量由傳感器、微處理器以及通信模塊共同組合而成的微型節(jié)點(diǎn)部署在待監(jiān)控區(qū)域當(dāng)中，這些節(jié)點(diǎn)能夠自組織構(gòu)成無(wú)線局域網(wǎng)絡(luò)，收集監(jiān)測(cè)數(shù)據(jù)，通過(guò)多跳的方式將監(jiān)測(cè)到的關(guān)于洪水的信息無(wú)線發(fā)送到監(jiān)測(cè)中心，組成水文無(wú)線傳感器防洪預(yù)警系統(tǒng)。它是解決傳統(tǒng)的防洪預(yù)警信息采集技術(shù)存在觀測(cè)點(diǎn)少、數(shù)據(jù)采集慢、傳輸不可靠等缺點(diǎn)的有效辦法。 本文主要針對(duì)湖南省衡陽(yáng)市的湘江河，展開了基于ZigBee協(xié)議的無(wú)線傳感器網(wǎng)絡(luò)的防洪預(yù)警技術(shù)研究。首先介紹了選題背景、國(guó)內(nèi)外研究現(xiàn)狀、論文主要研究?jī)?nèi)容，為選擇基于ZigBee的無(wú)線傳感器網(wǎng)絡(luò)提供前提理論基礎(chǔ)；然后對(duì)無(wú)線傳感器網(wǎng)絡(luò)和ZigBee協(xié)議進(jìn)行了相關(guān)的簡(jiǎn)單介紹；通過(guò)對(duì)網(wǎng)絡(luò)結(jié)構(gòu)以及系統(tǒng)應(yīng)用環(huán)境的分析，對(duì)系統(tǒng)整體進(jìn)行了設(shè)計(jì)；其次對(duì)論文的核心模塊部分，網(wǎng)絡(luò)內(nèi)各個(gè)節(jié)點(diǎn)的硬件和軟件的詳細(xì)設(shè)計(jì)進(jìn)行了介紹，硬件設(shè)計(jì)采用CC2530主芯片和CC2591射頻芯片來(lái)實(shí)現(xiàn)，并給出了協(xié)調(diào)器節(jié)點(diǎn)、路由器節(jié)點(diǎn)、終端節(jié)點(diǎn)的軟件設(shè)計(jì)流程圖；接著介紹了監(jiān)控中心的設(shè)備選型設(shè)計(jì)，利用LabVIEW軟件作為分析處理數(shù)據(jù)的工具進(jìn)行實(shí)時(shí)數(shù)據(jù)分析顯示；之后給出確定預(yù)警參數(shù)的方法，并在實(shí)驗(yàn)室條件下對(duì)系統(tǒng)進(jìn)行了仿真測(cè)試；最后對(duì)本文所做的研究工作進(jìn)行了總結(jié)，，并對(duì)工作中的不足進(jìn)行了展望。
[Abstract]:Hydrology is the basic work of water conservancy and is highly valued by governments at all levels. Flood control early warning is the basis of hydrological work. It plays an extremely important role in ensuring flood control safety, property safety, economic development and so on. Our country is flood-prone country, how to carry on the effective flood control early warning work, is very important. With the continuous development of science and technology, the traditional flood control early warning technology can not fully meet the expectations and requirements of flood control early warning. Wireless sensor network (WSN,Wireless Sensor Networks) has the advantages of self-organization, fast deployment, strong interference shielding and no manual guard. A large number of micro-nodes composed of sensors, microprocessors and communication modules are deployed in the monitoring area. These nodes can self-organize into a wireless local area network to collect monitoring data. The information about flood is sent wireless to the monitoring center by multi-hop method, and the hydrological wireless sensor flood prevention and warning system is formed. It is an effective method to solve the shortcomings of traditional flood control and early warning information collection technology, such as few observation points, slow data acquisition, unreliable transmission and so on. This paper focuses on the Xiangjiang River in Hengyang City, Hunan Province, and studies the flood control and early warning technology of wireless sensor networks based on ZigBee protocol. Firstly, this paper introduces the background of the selected topic, the current research situation at home and abroad, the main research contents, and provides the theoretical basis for choosing the wireless sensor network based on ZigBee. Then, it introduces the wireless sensor network and ZigBee protocol. Through the analysis of the network structure and the system application environment, the whole system is designed. Secondly, the core module of the paper, the detailed design of the hardware and software of each node in the network are introduced. The hardware design is realized by CC2530 main chip and CC2591 RF chip, and the software flow chart of coordinator node, router node and terminal node is given. The LabVIEW software is used as the tool to analyze and process the data, and then the method of determining the early warning parameters is given, and the system is simulated and tested under the condition of laboratory. Finally, the research work done in this paper is summarized, and the shortcomings of the work are prospected.
