【摘要】：物聯(lián)網(wǎng)作為時下的新興科技,隨著對其研究和應用的廣泛發(fā)展,備受世界各國科技人的青睞。物聯(lián)網(wǎng)首先是將實際環(huán)境中需要監(jiān)控、連接與互動的物體組建成一個無線傳感網(wǎng)絡,然后利用各種終端信息采集設備,實時地檢測收集各種需要的信息,再與互聯(lián)網(wǎng)結(jié)合構成一個巨大的線上與線下交互的通訊系統(tǒng),進而實現(xiàn)物與物之間的網(wǎng)絡信息交互和共享。 引黃入晉工程是一項大型跨流域引水工程。該工程從黃河萬家寨水庫取水,分別向太原、朔州和大同3個能源基地供水,以解決嚴重的缺水危機。由于這樣一個特定的工程應用背景,一般很難通過架設有線設備來完成對水域?qū)崟r水情信息的監(jiān)測和數(shù)據(jù)的傳輸,在這種情況下,無線通信的優(yōu)勢顯得更加明顯。而且在被測環(huán)境中,需要測量水位、水壓等多項參數(shù),這就為多個測量點組建網(wǎng)絡提出了應用需求。多個參數(shù)的測量往往集中在一定的區(qū)域范圍內(nèi),又為組建Zigbee無線傳感器網(wǎng)絡在通訊距離上提供了可行性。因此,我們結(jié)合Zigbee和GPRS的技術特性設計了一個基于Zigbee-GPRS的無線網(wǎng)絡水情監(jiān)測系統(tǒng)。 本文根據(jù)無線傳感器網(wǎng)絡的組成原理、通信協(xié)議和對引黃入晉工程被測環(huán)境中水情監(jiān)測需求的分析,設計了一個整體的硬件和軟件方案,并且進行了實驗驗證和分析。該方案綜合了Zigbee的自組織、短距離、低功耗特性和GPRS的遠程傳輸優(yōu)勢,將各個水情檢測設備通過CC2530芯片設計成網(wǎng)絡終端采集節(jié)點,在一定范圍內(nèi)實現(xiàn)星型拓撲結(jié)構組網(wǎng),再通過Zigbee協(xié)調(diào)器節(jié)點與GPRS模塊實現(xiàn)與上位機軟件的無線通訊,從而實現(xiàn)監(jiān)測區(qū)域內(nèi)的無線網(wǎng)絡水情監(jiān)測。軟件方面,設計了基于Labview的上位機監(jiān)測軟件,可以在線實時地監(jiān)測環(huán)境中的各個節(jié)點的參數(shù),并通過曲線圖表進行顯示,同時將采集到的數(shù)據(jù)保存到數(shù)據(jù)庫中,以便于查詢和維護采集到的水情數(shù)據(jù)。 整個設計以無線傳感器網(wǎng)絡為基礎,實現(xiàn)了現(xiàn)代化、網(wǎng)絡化的水情監(jiān)測,具有一定的工程實際意義。經(jīng)過試驗分析和驗證,此系統(tǒng)能夠穩(wěn)定運行,基本滿足了遠程水情監(jiān)測的無線網(wǎng)絡化和現(xiàn)代智能化需求。通過整個系統(tǒng)的設計,終端設備、互聯(lián)網(wǎng)與人有效的連接到了整個網(wǎng)絡中,實現(xiàn)了高質(zhì)量的信息共享服務。 通過對無線傳感器網(wǎng)絡節(jié)點部署模型的學習和分析,我們設計了一個基于鄰居節(jié)點平均距離的無線傳感器網(wǎng)絡覆蓋判別模型,此模型較傳統(tǒng)的網(wǎng)絡覆蓋模型可以更好地節(jié)約無線傳感器網(wǎng)絡中工作節(jié)點的數(shù)量。
[Abstract]:Internet of things (IOT) as a new technology, with the extensive development of its research and application, is favored by the scientific and technological people all over the world. Objects connected to and interacted with each other form a wireless sensor network, and then use various terminal information acquisition devices to detect and collect all kinds of information needed in real time, and then combine with the Internet to form a huge online and offline communication system. Then realize the network information exchange and sharing between things and objects. The Yellow River diversion Project is a large cross-basin water diversion project. The project draws water from the Wanjiazhai Reservoir of the Yellow River and supplies water to three energy bases, Taiyuan, Shuozhou and Datong, respectively. In order to solve the serious water shortage crisis. Because of such a specific engineering application background, it is generally difficult to complete the monitoring of real-time water regime information and the transmission of data through the erection of wired equipment. In this case, The advantages of wireless communication are more obvious. Moreover, in the measured environment, many parameters, such as water level, water pressure and so on, need to be measured. Therefore, the measurement of multiple parameters is often concentrated in a certain area, which provides the feasibility of constructing Zigbee wireless sensor network in communication distance. Combining the technical characteristics of Zigbee and GPRS, we design a wireless network hydrologic monitoring system based on Zigbee-GPRS. According to the composing principle of wireless sensor network, the communication protocol and the analysis of the water condition monitoring requirement in the measured environment of the Yellow River diversion Project, a whole hardware and software scheme is designed in this paper. The scheme integrates the advantages of self-organization, short distance, low power consumption and remote transmission of GPRS, and designs each hydrologic detection device into a network terminal acquisition node through CC2530 chip. In a certain range of star topology network, and then through the Zigbee coordinator node and GPRS module to achieve wireless communication with the host computer software, so as to achieve the monitoring of wireless network hydrological monitoring in the region. Software, The monitoring software of upper computer based on Labview is designed, which can monitor the parameters of each node in the environment in real time on line, and display it by curve chart, at the same time, the collected data can be saved to the database. To facilitate the query and maintenance of collected hydrological data. The whole design is based on wireless sensor network and realizes the modern and networked monitoring of water regime. It has certain engineering practical significance. After experimental analysis and verification, the system can run stably. Through the design of the whole system, the terminal equipment, the Internet and the person are effectively connected to the whole network, and the high quality information sharing service is realized. By studying and analyzing the node deployment model of wireless sensor network, we design a wireless sensor network coverage discriminant model based on the average distance of neighbor nodes. Compared with the traditional network coverage model, this model can save the number of working nodes in wireless sensor networks.
