交通信号灯自动识别技术的研究摘要中国不仅是城市道路等基础设施建设速度最快的国家，也是交通需求增长最快的国家。特别是近年来，机动车数量迅速增加，导致交通问题越来越严重，传统的车辆管理方法越来越难以有效管理。目前道路车辆监控技术主要是图像或视频识别，这种非法视频采集技术和电子相机监控技术在实际应用中存在一定的不足。自动识别技术为实现车辆信息数字化、车辆识别自动化、车辆管理智能化提供了良好的前端信息平台，已逐步应用于铁路车辆自动识别、道路车辆识别、集装箱识别、停车场管理等交通领域。本文以城市道路车辆为研究对象，通过在车辆上安装RFD电子标签，在城市道路交叉口和路段安装读取装置，自动识别车辆通过，最后基于模糊控制理论进行仿真实验，从而检验其可行性，如果可行，这样可以限制驾驶员的违法行为，实现对车辆的监控，完善城市道路车辆监控手段，弥补现有道路监控技术的漏洞，提高城市道路交通的效率，从而减少交通拥堵，减少车辆通过交叉口的延误时间。关键字：交通信号灯；自动识别：智能化；监控1AbstractChina is not only the fastest growing country in urban road infrastructureconstruction,but also the fastest growing country in traffic demand.Especially inrecent years,the number of motor vehicles has increased rapidly,which leads to moreand more serious traffic problems.The traditional method of vehicle management ismore and more difficult to manage.At present,road vehicle monitoring technology is mainly about image or videorecognition.Such illegal video collection technology and electronic cameramonitoring technology have some deficiencies in practical application.Automaticidentification technology provides a good platform for the realization of informationfront vehicle information digitization,vehicle identification automation,intelligentvehicle management,has been gradually applied in railway vehicle automaticidentification,road vehicle identification,container identification,parking and trafficmanagement field.Based on city road vehicle as the research object,through the installation ofRFID electronic label on the vehicle mounted reading device in the city roadintersection and road,automatic recognition of the vehicle through which based onfuzzy control theory and simulation experiment to test its feasibility,if feasible,suchviolations can limit the driver,to achieve control of the vehicle perfect city,roadvehicle monitoring means,make up the existing road monitoring technologyvulnerabilities,enhance the efficiency of city road traffic,so as to reduce trafficcongestion,reduce the delay time of vehicles through the intersection.Keyword:traffic signal lamp;automatic recognition;intelligent;monitoring目录1.1选题背景及意义41.2国内外研究现状及进展41.2.1国外研究现状..1.2.2国内研究现状....552.2自动识别系统的一般模型673.1识读器工作方式配置73.2识读器参数设置..894、交通信号灯自动识别仿真104.1交通信号控制的基本概念..1011114.2.2实现模糊控制的步骤12134.4十字路口交通信号模糊控制器的设计144.4.1确定输入、输出变量.....144.4.2隶属度函数曲线以及修正算法154.4.3模糊控制规则的制定......164.4.4模糊推理.......174.5系统仿真及结果分析...18总结19参考文献202125
