【摘要】：随着社会经济的发展，城市路灯照明系统已经成为展示城市魅力的窗口，路灯照明系统在带来方便和美观的同时，也遇到了诸多问题，目前各大城市路灯的路灯利用率不高，电能浪费严重。同时近年来各类工业污染事件不断发生，席卷中国中东部地区的雾霾天气现象增多，对于雾霾导致的城市能见度低，现有城市照明系统并没有对其做出响应。因此市政部门需要一种效率高、能耗低的智能路灯控制系统。 针对这一问题本文设计了一种新型智能路灯控制系统，通过ZigBee和GPRS通信技术以及多传感器的结合，可以实现路灯的智能控制响应、环境参数采集以及节约能源等功能。本文的主要研究内容如下： （1）本文对智能路灯网络进行需求分析，提出了本文设计的网络组网要求并指出了网络特征。基于网络需求设计一种改进的AODVjr路由协议，采用OPNET仿真软件对路灯可行性分析同时对数据进行分析。 （2）设计了一款基于STM32的嵌入式系统，实现对路灯的远程控制和环境参数的采集、存储。利用SIM900A实现智能网关与监测中心的通信与数据传输，组建无线ZigBee短距离自组网，保证路灯网络畅通和及时自我修复。 （3）对仪器性能进行测试，采集部分结果表明：温度分辨率为0.1℃，精度为98%、相对湿度分辨率0.1%，精度为98.5%、雾霾测量分辨率为0.1μg/m3，精度为95%。对GPRS模块的在不同时间间隔下的丢包率进行分析，最终确定5s作为数据发送间隔。模拟点对点和加入路由的ZigBee自组网模式，对ZigBee通信距离进行实际实验，确定ZigBee组网通信距离为80-100m。综上，本文设计的智能路灯控制系统符合实际要求。 本文研制了一种具有环境参数采集功能的智能路灯控制系统，改进了一种应用在智能路灯范围内的AODVjr路由协议，通过实验对于系统进行分别测试，，同时分析了误差，为今后的研究提供了经验。
[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
