【摘要】：隨著社會經濟的發(fā)展，城市路燈照明系統(tǒng)已經成為展示城市魅力的窗口，路燈照明系統(tǒng)在帶來方便和美觀的同時，也遇到了諸多問題，目前各大城市路燈的路燈利用率不高，電能浪費嚴重。同時近年來各類工業(yè)污染事件不斷發(fā)生，席卷中國中東部地區(qū)的霧霾天氣現(xiàn)象增多，對于霧霾導致的城市能見度低，現(xiàn)有城市照明系統(tǒng)并沒有對其做出響應。因此市政部門需要一種效率高、能耗低的智能路燈控制系統(tǒng)。 針對這一問題本文設計了一種新型智能路燈控制系統(tǒng)，通過ZigBee和GPRS通信技術以及多傳感器的結合，可以實現(xiàn)路燈的智能控制響應、環(huán)境參數(shù)采集以及節(jié)約能源等功能。本文的主要研究內容如下： （1）本文對智能路燈網(wǎng)絡進行需求分析，提出了本文設計的網(wǎng)絡組網(wǎng)要求并指出了網(wǎng)絡特征�；诰W(wǎng)絡需求設計一種改進的AODVjr路由協(xié)議，采用OPNET仿真軟件對路燈可行性分析同時對數(shù)據(jù)進行分析。 （2）設計了一款基于STM32的嵌入式系統(tǒng)，實現(xiàn)對路燈的遠程控制和環(huán)境參數(shù)的采集、存儲。利用SIM900A實現(xiàn)智能網(wǎng)關與監(jiān)測中心的通信與數(shù)據(jù)傳輸，組建無線ZigBee短距離自組網(wǎng)，保證路燈網(wǎng)絡暢通和及時自我修復。 （3）對儀器性能進行測試，采集部分結果表明：溫度分辨率為0.1℃，精度為98%、相對濕度分辨率0.1%，精度為98.5%、霧霾測量分辨率為0.1μg/m3，精度為95%。對GPRS模塊的在不同時間間隔下的丟包率進行分析，最終確定5s作為數(shù)據(jù)發(fā)送間隔。模擬點對點和加入路由的ZigBee自組網(wǎng)模式，對ZigBee通信距離進行實際實驗，確定ZigBee組網(wǎng)通信距離為80-100m。綜上，本文設計的智能路燈控制系統(tǒng)符合實際要求。 本文研制了一種具有環(huán)境參數(shù)采集功能的智能路燈控制系統(tǒng)，改進了一種應用在智能路燈范圍內的AODVjr路由協(xié)議，通過實驗對于系統(tǒng)進行分別測試，，同時分析了誤差，為今后的研究提供了經驗。
[Abstract]:With the development of social economy, the city street lamp lighting system has become the window to show the charm of the city. While the street lamp lighting system brings convenience and beauty, it also meets many problems. At present, the utilization ratio of the street lamp in every big city is not high. There is a serious waste of electricity. At the same time, various industrial pollution incidents have occurred in recent years, and the haze weather phenomenon sweeping the central and eastern part of China has increased, and the existing urban lighting system has not responded to the low visibility caused by haze. Therefore, municipal departments need an intelligent street lamp control system with high efficiency and low energy consumption. In order to solve this problem, a new type of intelligent street lamp control system is designed in this paper. Through the combination of ZigBee and GPRS communication technology and multi-sensor, the intelligent control response of street lamp, the collection of environmental parameters and the saving of energy can be realized. The main contents of this paper are as follows: (1) the requirement of intelligent streetlight network is analyzed in this paper. An improved AODVjr routing protocol is designed based on the network requirements. The feasibility analysis of street lamp and the analysis of data are carried out by using OPNET simulation software. (2) an embedded system based on STM32 is designed to realize the remote control of street lamp and the collection and storage of environmental parameters. The communication and data transmission between the intelligent gateway and the monitoring center is realized by using SIM900A, and the wireless ZigBee short distance ad hoc network is constructed to ensure the smooth and timely self-repair of the street lamp network. (3) the performance of the instrument is tested. The results show that the temperature resolution is 0.1 鈩
