【摘要】：如何實現(xiàn)水情測報系統(tǒng)的自動化,是目前在水利工程領(lǐng)域的一個研究熱點。隨著物聯(lián)網(wǎng)技術(shù)的不斷發(fā)展和成熟,使得通過無線技術(shù)將傳感器終端采集的數(shù)據(jù)發(fā)送到人們需要的地方成為了一種可能。為了實現(xiàn)在遠程對水位數(shù)據(jù)進行監(jiān)控和管理,我們將現(xiàn)有的嵌入式技術(shù)同物聯(lián)網(wǎng)技術(shù)相結(jié)合,對無線水位傳感器的設(shè)計進行了研究。 本文在研究了目前國內(nèi)外研究現(xiàn)狀并在做了一部分基礎(chǔ)實驗的背景下,提出并設(shè)計了一款基于ZigBee技術(shù)的無線水位傳感器系統(tǒng)。本系統(tǒng)主要包括三部分：一是以ZigBee技術(shù)為基礎(chǔ)的無線通信網(wǎng)絡(luò)部分,這部分的設(shè)計使用了CC2530模塊,主要是為了實現(xiàn)傳感器節(jié)點的無線組網(wǎng),使得各個傳感器節(jié)點采集到的數(shù)據(jù)可以進行匯總查詢；二是以MSP430F2013單片機為核心的智能變送器部分,該部分利用感應(yīng)式數(shù)字水位傳感器對水位數(shù)據(jù)進行采集,并且將非標準電流信號轉(zhuǎn)換成標準的信號,通過ZigBee模塊將信號發(fā)送給協(xié)調(diào)器；三是以S3C2440為核心的嵌入式控制入網(wǎng)部分,這部分主要實現(xiàn)數(shù)據(jù)的入網(wǎng)功能,并且使用HTML語言編寫程序,結(jié)合BOA+CGI技術(shù)實現(xiàn)PC機上的查詢功能。本課題有如下特點： (1)在原有的傳感器基礎(chǔ)上結(jié)合了ZigBee技術(shù),使得眾多傳感器節(jié)點可以進行自行組網(wǎng)和數(shù)據(jù)交流,而且一個傳感器網(wǎng)絡(luò)只需要一個ARM控制器即可實現(xiàn)眾多節(jié)點數(shù)據(jù)的入網(wǎng),節(jié)省了系統(tǒng)成本； (2)選用的變送器主控芯片功耗低,使整個系統(tǒng)可以運行更長的時間而不必更換電源,符合將來在實際應(yīng)用領(lǐng)域的要求； (3)嵌入式系統(tǒng)部分的設(shè)計比較簡單,易于操作,只需要用一個網(wǎng)卡便可以實現(xiàn)入網(wǎng)功能,而且S3C2440芯片還有很多接口,對進一步的開發(fā)工作很有利； (4)軟件部分設(shè)計時也考慮了降低功耗的因素,編寫過程中盡量使用功耗低的指令以及32位整型數(shù)據(jù)； (5)設(shè)計了網(wǎng)絡(luò)查詢頁面,方便遠程查詢。 經(jīng)過實驗驗證后,系統(tǒng)基本達到了論文開始時的設(shè)計要求,實現(xiàn)遠程數(shù)據(jù)查詢功能。為將來進一步的設(shè)計完善和實踐應(yīng)用做了充足的準備。
[Abstract]:How to realize the automation of hydrological information system is a research hotspot in the field of water conservancy engineering at present. With the continuous development and maturity of Internet of things technology, It is possible to transmit the data collected by the sensor terminal to where people need it through wireless technology. In order to realize the remote monitoring and management of water level data, We study the design of wireless water level sensor by combining the existing embedded technology with the Internet of things technology. In this paper, we have studied the current research situation at home and abroad and done some basic experiments. A wireless water level sensor system based on ZigBee technology is proposed and designed. The system mainly includes three parts: one is the wireless communication network based on ZigBee technology, which uses CC2530 module. The main purpose is to realize the wireless network of sensor nodes, so that the data collected by each sensor node can be collected and queried; second, the intelligent transmitter part based on MSP430F2013 microcontroller. This part uses the inductive digital water level sensor to collect the water level data, and converts the non-standard current signal into the standard signal, and sends the signal to the coordinator through the ZigBee module. The third part is the embedded control network part, which takes S3C2440 as the core. This part mainly realizes the data access function, and uses the HTML language to write the program, unifies the BOA CGI technology to realize the personal computer inquiry function. This topic has the following characteristics:. 1) combining the ZigBee technology with the original sensor, many sensor nodes can organize their own network and exchange data. Moreover, a sensor network only needs one ARM controller to access the data of many nodes. The system cost is saved; 2) the power consumption of the main control chip of the selected transmitter is low, so that the whole system can run for longer time without replacing the power supply, which conforms to the requirements of the practical application field in the future; The design of embedded system is relatively simple and easy to operate, only one network card can be used to realize the network function, and there are many interfaces in the S3C2440 chip, which is very beneficial to the further development. In the software design, the factors of reducing power consumption are also taken into account, and the instructions with low power consumption and 32-bit integer data are used as far as possible in the process of writing. A web query page is designed to facilitate remote query. After experimental verification, the system basically meets the design requirements at the beginning of the paper, and realizes the function of remote data query, which makes sufficient preparation for further design improvement and practical application in the future.
