【摘要】：随着我国经济快速增长,汽车保有量不断增加,汽车种类和数量不断增多,交通管理压力日趋繁重,车辆监管日益繁琐,常因交管部门执法检查技术手段及措施的不完善,给已经严重堵塞的交通雪上加霜,而频发的汽车盗窃、逃税等现象给人民群众造成严重危害,也为我国的税费收入带来极大的损失。如何更好地解决这些实际问题,快速、准确、及时获取车辆信息实现科学管理,已成为交管部门急需解决的问题。因此及时获得运动车辆信息甚至定位信息,对于提高车辆缴费收费的运行效率、保障行车安全、打击偷税漏税、追捕逃犯等有着重要的现实意义。从以上现状出发,本文利用嵌入式技术、无线网络通信技术和GPS定位技术设计了一套车辆信息的综合管理平台,提出了基于车载平台车辆管理信息更新、显示、远端平台信息采集等功能的交互系统设计思想,实现了车辆在特定区域内定位信息采集,通过无线网络,实现对多个运动车辆实时、快速地车辆信息执法查询。车辆信息管理系统主要包括：车辆本身信息查询(如车牌号、发动机号等)、车辆定位信息(车辆当前地理位置)、车辆管理信息(如是否年检、是否缴纳交强险,汽车尾气排放国标检测是否达标)等。交管部门可将车辆的这些最新信息在无线网络有效的范围内发送到每辆车的车载平台上进行显示,同时也可通过该网络对每辆车的信息进行快速查询。实现对合格车辆及时放行,快速过滤不合格车辆并及时拦截处理。系统主要包括：车载平台、上位机PC控制平台(便携式手持控制平台)、无线通信。车载平台采用嵌入式技术实现GPS信息采集、保存、显示；解析上位机PC控制平台命令；实现相应命令的数据返回、信息显示、内容更新；与上位机PC控制平台进行数据交互。上位机PC控制平台采用QT实现控制系统界面设计和通信,实现操作命令发送、车载信息的读取、车载信息显示、发送修改指令、与车载平台信息交互。便携式手持控制平台实现与上位机控制平台同样功能,方便交管部门执法操作。无线通信是系统信息传递的载体,是实现信息交互的重要组成部分,自定义了系统通信协议。系统采用嵌入式技术对车载部分进行详细设计,实现实时显示定位信息、接收和解析控制命令,及时做出信息反馈、更新；实现系统无线通信协议编写,上位的控制系统界面设计,车辆信息和实时地图显示；手持设备采用和车载平台同样硬件设备和软件环境,为进一步深入研究设计打下基础。
[Abstract]:With the rapid economic growth of our country, the number of vehicles is increasing, the types and quantity of vehicles are increasing, the pressure of traffic management is becoming more and more heavy, the supervision of vehicles is becoming more and more complicated, and the technical means and measures of law enforcement and inspection of traffic control departments are not perfect.The traffic has been seriously blocked, and the frequent car theft, tax evasion and other phenomena have caused serious harm to the people, and also brought great loss to the tax revenue of our country.How to better solve these practical problems and how to obtain vehicle information quickly, accurately and timely to achieve scientific management has become an urgent problem for traffic management departments.So it is of great practical significance to obtain the information of sports vehicles and even the location information in time to improve the efficiency of vehicle fees and charges, to ensure the safety of driving, to crack down on tax evasion, and to hunt down fugitives.Based on the above situation, this paper designs a vehicle information integrated management platform based on embedded technology, wireless network communication technology and GPS positioning technology, and proposes a vehicle management information update based on vehicle platform.The design idea of interactive system of remote platform information collection and other functions realizes the vehicle location information collection in a specific area. Through the wireless network, it realizes the real-time and fast vehicle information enforcement inquiry for a number of moving vehicles.Vehicle information management system mainly includes: vehicle information query (such as license plate number, engine number, etc.), vehicle location information (vehicle current geographical location, vehicle management information (such as annual inspection, whether to pay traffic insurance, etc.),Automobile exhaust emission national standard detection is up to standard) etc.The traffic control department can send the latest information of the vehicle to the on-board platform of each vehicle within the effective range of the wireless network, and can also query the information of each vehicle quickly through the network.Achieve timely release of qualified vehicles, fast filtering of unqualified vehicles and timely interception and processing.The system mainly includes: vehicle platform, PC control platform (portable handheld control platform, wireless communication).The vehicle platform uses embedded technology to realize GPS information collection, storage, display; parse PC control platform command; to achieve the corresponding command data return, information display, content update; and PC control platform for data interaction.The PC control platform uses QT to realize the interface design and communication of the control system, to realize the sending of operation command, the reading of on-board information, the display of on-board information, the sending of modification instruction, and the interaction with the information of on-board platform.The portable handheld control platform realizes the same function as the upper computer control platform, which is convenient for traffic control department to enforce the law.Wireless communication is the carrier of system information transmission and an important part of information exchange.The system uses embedded technology to carry on the detailed design to the vehicle part, realizes the real-time display localization information, receives and analyzes the control command, timely makes the information feedback, updates, realizes the system wireless communication protocol compilation,The upper control system interface design, vehicle information and real-time map display, and the handheld devices use the same hardware and software environment as the on-board platform, which lays the foundation for further research and design.
