【摘要】 基于射频识别(RFID)、全球定位系统和摄像头拍摄等物联网技术,实现车辆信息的实时采集及车辆的全程跟踪与定位,增强车辆信息获取手段,提高车辆管理的效率,完善和提升公安在车辆管理中的信息化水平。针对车辆的基本信息、各种情况信息和定位信息,利用物联网与移动通讯技术,开展基于物联网技术的车辆跟踪定位方案设计。主要研究内容包括:(1)车辆跟踪定位系统的设计。从物联网技术在车辆管理中的应用构架出发,对系统总体方案进行详细的阐述,将设计方案分为三个层次,分别是感知层、网络层和应用层,并对每层的功能和作用进行简要的介绍。对感知层、网络层和应用层的逻辑结构和设计方法进行详细的介绍。(2)车辆信息的采集与入库方案的设计。从车辆信息的分类出发,把信息分为由射频识别(RFID)采集的车辆基本信息、由摄像头采集的车辆视频图片声音信息和由GPS设备采集的车辆定位信息三大类信息。分别存储在三个不同的服务器中,其中车辆的基本信息与车辆的视频图片声音信息存储于普通服务器中,车辆的定位信息利用云存储技术存储于云端数据库中。每个服务器再把信息进行分成若干个小类进行存储,把时间信息、车牌号码、经度、纬度和车主姓名等信息进行分类存储,以便查找与调用。(3)车辆与系统网络通讯方案的设计。从硬件的布设出发,介绍车辆信号源从采集端到用户终端的移动通讯技术及移动站与基站的布设方案。车辆信号通过有线方式从信号采集器传输到与之绑定的移动站,再通过移动通讯技术从移动站传送给基站,进而通过有线方式传送给相应服务器,服务器再根据用户终端的请求条件,把相应的信息通过有线的方式传送给用户终端,最后通过可视化界面传递给用户。对信号进行放大处理,并为系统设计防干扰电路。(4)车辆跟踪定位用户端的设计。利用LabVIEW开发平台,开发人性化的用户端软件。从软件的程序设计出发,介绍主程序的设计方法和串口数据通信的设计方案,并对用户端软件的操作界面及使用方法进行详细的说明。通过案例说明根据用户端输入的车辆的基本信息,搜索到汽车的定位信息并结合地图把车辆的具体位置在地图上标识出来,达到对车辆跟踪定位目的的过程。
【Abstract】 Based on radio frequency identification devices(RFID),global positioning system,camera shooting and other Internet of Things technology which can realizing the collection of vehicle information in real time and vehicle’s tracking and positioning through the whole journey,enhancing vehicle information acquisition approaches to improve vehicle management efficiency,and also enhancing the level of informatization in police’s vehicle management.Specific to basic information of vehicle,various conditions and position information,making use of the Internet of Things and mobile communication technology to carry out vehicle tracking and positioning project design based on the Internet of Things technology.The main contents include:(1)Design of vehicle tracking and positioning systems.From the Internet of Things technology’s application framework in the vehicle management todemonstrate the overall project in details.The design scheme is divided into three levels,namely the sensing layer,network layer and application layer,and we will have a brief introduction of each layer’s function and effect.Furthermore,have detailed introduction to the logical structure and design methods of sensing layer,network layer and application layer.(2)Design of vehicle information collection and storage plan.Starting from theclassification of the vehicle information,dividing vehicle information into three categories,as the basic information collected by radio frequency identification devices(RFID),the video,image and audio information captured by the vehicle camera,and the vehicle position information collected by the GPS device.Respectively stored in three different servers,as for the basic information of the vehicle and the vehicle’s video,image and audio information is stored in the ordinary server,position information of the vehicle utilizing cloud storage technology to store in the cloud database.Each server is divided information into several subcategories and then stored,the time information,license plate number,latitude,longitude and name of the owner stored by classified so as to find and call easily.(3)Design of the vehicle and the network communications project.From thehardware layout,introducing mobile communication technology of vehicle’s signal source from collection terminal to user terminal,also the layout scheme of mobile station and base station.Vehicle signal transmission by cable from signal collector to the binding mobile station,and transmitted from the mobile station to the base station through the mobile communication technology,and then sent to the appropriate server by cable,next the server at the request of the user terminal,the corresponding information is transmitted via wire mode to the user terminal,and finally delivered to the user through a visual interface.To amplify the signal and design an Anti-interference circuit for the system.(4)Vehicle tracking and positioning client terminal design.Using LabVIEW development platform to develop user-friendly client software.Begin with the software program design,and then introduce the design method of the main program and the design scheme of serial data communication.What’s more,detailed description of the client software’s operation interface and the use method.To illustrate the process of according to the vehicle’s basic information the client entered to search the car’s position information and combined with maps to identify the specific location of the vehicle on the map,to achieve the purpose of vehicle tracking and positioning.
