【摘要】：随着我国城市化进程日益加快,加强城市基础设施建设已经越来越受到来自国家的高度重视和全社会的广泛关注。路灯作为城市基础设施建设的一部分,不但与市民的日常生活密不可分,而且在城市的治安管理、交通出行和市容市貌等领域扮演着极为重要的角色,而路灯监控系统的设计水平,也从一个侧面反映了城市化水平的高低。当前路灯监控系统普遍存在着开关灯方式落后、后半夜能耗严重、维护效率低等问题。 针对以上原因,本文设计了一套基于交通流检测的路灯节能监控系统,系统采用监控中心、监控子站和监控终端三层监控结构,采用GPRS和ZigBee结合的两层组网方式,其整体设计思路是：监控中心根据自然环境照度信息统一控制全市路灯的开关；路灯开启后,监控子站引入RFID技术实时检测各个道路入口的交通流信息,以交通流信息为依据调节路灯的电压,控制路灯的亮度。 本文首先介绍了论文背景和研究意义,简要介绍了路灯监控系统的国内外研究现状,然后介绍了将交通流检测技术引入路灯监控系统的科学依据,根据系统设计思路,通过对比分析现有交通流检测技术,引入了适合本系统交通流检测功能的RFID技术,对比分析现有短距离无线通信技术,确定了实现单灯监控的ZigBee技术,并设计出系统交通流检测技术的实际方案和ZigBee子网的网络拓扑结构。 本文对系统进行了较详细的软硬件设计。论文首先对路灯监控终端进行了详细的硬件设计,主要概述了路灯监控终端的硬件组成,并详细介绍了可控硅调压原理和电路设计,而后对监控子站进行了模块化硬件设计。在对监控终端和监控子站进行总体软件设计前,介绍了系统ZigBee模块软件设计流程,包括ZigBee软件开发工具、ZigBee协议栈、ZigBee网络设置、ZigBee路由算法、ZigBee通信帧格式和各监控节点ZigBee应用层软件设计流程,而后从路灯降压节能的科学依据、节能电压阈值确定、城市道路交通流状态划分、基于指数平滑法的交通流预测模型设计出基于交通流服务水平的路灯节能策略。最后介绍了监控子站和监控中心相关监控软件的设计与模拟实现,并对全文进行了总结和展望。
[Abstract]:With the rapid urbanization of our country , the construction of urban infrastructure has become more and more popular with the high priority from the nation and the wide concern of the whole society . As part of the urban infrastructure construction , the street lamp not only plays a very important role in the city ' s daily life , but also reflects the level of urbanization from one side .
Aiming at the above reasons , a set of traffic flow detection - based street lamp energy - saving monitoring system is designed . The monitoring center , the monitoring substation and the monitoring terminal three - layer monitoring structure are adopted , and the two - layer networking mode combining GPRS and ZigBee is adopted , and the overall design idea is that the monitoring center controls the switch of the whole city street lamp according to the natural environment illumination information ;
After the street lamp is turned on , the monitoring substation introduces the RFID technology to detect the traffic flow information of each road entrance in real time , and the traffic flow information is used for adjusting the voltage of the street lamp to control the brightness of the street lamp .
Firstly , the paper introduces the background and significance of the paper , introduces the current research situation of the road lamp monitoring system , introduces the RFID technology which is suitable for the traffic flow detection function of the system according to the design idea of the system , introduces the ZigBee technology suitable for the monitoring of the single lamp by comparing the existing short - range wireless communication technology , and designs the actual scheme of the system traffic flow detection technology and the network topology structure of the ZigBee sub - network .
