【摘要】：青草沙水庫是亞洲最大的河口江心水庫,位于長江下游區(qū)域,是上海目前最大的水源地。水庫內(nèi)目前已經(jīng)通過GPRS技術(shù)建立了無線傳感網(wǎng)絡(luò),但由于該區(qū)域的信號覆蓋問題,導(dǎo)致網(wǎng)絡(luò)的穩(wěn)定性較差,經(jīng)常出現(xiàn)數(shù)據(jù)監(jiān)測中斷的情況。根據(jù)這一情況,本文提出了基于ZigBee技術(shù)的水質(zhì)監(jiān)測無線傳感器網(wǎng)絡(luò)的組網(wǎng)方案。本文在研究了國內(nèi)外先進(jìn)的無線傳感器網(wǎng)絡(luò)應(yīng)用的基礎(chǔ)上,結(jié)合水庫實(shí)際情況,選擇了數(shù)據(jù)傳輸可靠,網(wǎng)絡(luò)容量大的ZigBee技術(shù)。本文詳細(xì)研究了ZigBee技術(shù)的核心內(nèi)容,并以集成微控制器的射頻芯片CC2530結(jié)合射頻前端放大芯片CC2591為基礎(chǔ)設(shè)計(jì)了節(jié)點(diǎn)模塊的硬件結(jié)構(gòu);以IAR Embedded Workbench為開發(fā)環(huán)境,實(shí)現(xiàn)了協(xié)調(diào)器組網(wǎng)、路由器入網(wǎng)、串口通信及協(xié)調(diào)器的廣播功能;以QT為開發(fā)平臺,設(shè)計(jì)了上位機(jī)軟件,實(shí)現(xiàn)了水質(zhì)數(shù)據(jù)的遠(yuǎn)程監(jiān)控;根據(jù)水庫的實(shí)際地理環(huán)境,對路由器節(jié)點(diǎn)進(jìn)行定位,并對網(wǎng)絡(luò)參數(shù)進(jìn)行調(diào)整,完成了整個無線傳感器網(wǎng)絡(luò)的設(shè)計(jì)工作。本文將ZigBee技術(shù)應(yīng)用于青草沙水庫的水質(zhì)監(jiān)測領(lǐng)域,實(shí)現(xiàn)了一定區(qū)域內(nèi)的水質(zhì)數(shù)據(jù)的遠(yuǎn)程監(jiān)控,在其他水環(huán)境監(jiān)測領(lǐng)域也具有一定的推廣意義。
[Abstract]:Qingcaosha Reservoir is the largest estuarine reservoir in Asia, located in the lower reaches of the Yangtze River and the largest source of water in Shanghai. The wireless sensor network has been established by GPRS technology in the reservoir at present, but because of the problem of signal coverage in this area, the stability of the network is poor, and the data monitoring is often interrupted. According to this situation, this paper proposes a network scheme of water quality monitoring wireless sensor network based on ZigBee technology. On the basis of studying the advanced wireless sensor network applications at home and abroad and combining with the actual situation of the reservoir, this paper selects the ZigBee technology which is reliable in data transmission and has large network capacity. In this paper, the core content of ZigBee technology is studied in detail, and the hardware structure of node module is designed on the basis of RF chip CC2530 integrated microcontroller and RF front-end amplifier chip CC2591, and the network of coordinator is realized by using IAR Embedded Workbench as development environment. Router access network, serial communication and the broadcast function of coordinator; with QT as the development platform, the software of upper computer is designed to realize the remote monitoring of water quality data; according to the actual geographical environment of the reservoir, the router node is located. The parameters of the wireless sensor network are adjusted to complete the design of the wireless sensor network. In this paper, ZigBee technology is applied to the field of water quality monitoring of Qingcaosha Reservoir, which realizes the remote monitoring of water quality data in a certain area, and also has certain popularization significance in other fields of water environment monitoring.
