【摘要】：水文是水利的基礎(chǔ)性工作，得到各級政府的高度重視。防洪預(yù)警是水文工作的基礎(chǔ)，做好防洪預(yù)警工作，對確保防洪安全、財產(chǎn)安全、經(jīng)濟發(fā)展等，具有極端重要的作用。我國是洪水多發(fā)國，怎么進行有效的防洪預(yù)警工作，至關(guān)重要。隨著當今科學(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、無需人工值守等優(yōu)點。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)點部署在待監(jiān)控區(qū)域當中，這些節(jié)點能夠自組織構(gòu)成無線局域網(wǎng)絡(luò)，收集監(jiān)測數(shù)據(jù)，通過多跳的方式將監(jiān)測到的關(guān)于洪水的信息無線發(fā)送到監(jiān)測中心，組成水文無線傳感器防洪預(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)存在觀測點少、數(shù)據(jù)采集慢、傳輸不可靠等缺點的有效辦法。 本文主要針對湖南省衡陽市的湘江河，展開了基于ZigBee協(xié)議的無線傳感器網(wǎng)絡(luò)的防洪預(yù)警技術(shù)研究。首先介紹了選題背景、國內(nèi)外研究現(xiàn)狀、論文主要研究內(nèi)容，為選擇基于ZigBee的無線傳感器網(wǎng)絡(luò)提供前提理論基礎(chǔ)；然后對無線傳感器網(wǎng)絡(luò)和ZigBee協(xié)議進行了相關(guān)的簡單介紹；通過對網(wǎng)絡(luò)結(jié)構(gòu)以及系統(tǒng)應(yīng)用環(huán)境的分析，對系統(tǒng)整體進行了設(shè)計；其次對論文的核心模塊部分，網(wǎng)絡(luò)內(nèi)各個節(jié)點的硬件和軟件的詳細設(shè)計進行了介紹，硬件設(shè)計采用CC2530主芯片和CC2591射頻芯片來實現(xiàn)，并給出了協(xié)調(diào)器節(jié)點、路由器節(jié)點、終端節(jié)點的軟件設(shè)計流程圖；接著介紹了監(jiān)控中心的設(shè)備選型設(shè)計，利用LabVIEW軟件作為分析處理數(shù)據(jù)的工具進行實時數(shù)據(jù)分析顯示；之后給出確定預(yù)警參數(shù)的方法，并在實驗室條件下對系統(tǒng)進行了仿真測試；最后對本文所做的研究工作進行了總結(jié)，，并對工作中的不足進行了展望。
[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.
