【摘要】 近年来地理信息系统得到了迅速发展,基于GIS的监控系统成为交通运输中对各种交通工具进行合理调度和安全管理的重要手段,但是不能满足监控人员对目标进行实时的实物观察。同样移动视频监控是近年来视频监控领域的重要研究方向,由于其更直接的直观性,同样被广泛用于安全管理和安全指挥等领域,但在交通运输监控领域,却不能获得监控目标的地理位置信息,随着汽车工业的不断发展,交通运输将日益繁重和复杂,一套既可以获得监控目标地理位置又能够实行实时视频监控的系统显得十分必要。有鉴于以上问题的应用背景和需求,将定位技术,图像技术,通信技术,地图技术,数据库技术等技术融合开发交通运输中,可以对车载移动目标实行定位及实时图像的双重监控具有现实意义。本文利用GPS卫星定位系统采集车载移动目标的地理位置,视频采集卡采集实时的现场图像,通过GPRS全球移动通信技术实现数据的无线传输,依托GIS丰富的地理信息和直观的现场图像对车辆实行远程监控,同时引用数据库技术设计并实现了本监控系统。本文对车载移动定位及图像监控系统的应用对象和应用范围进行了深入的研究,在分析系统的应用对象的基础上,从系统的设计目标,设计原则,总体结构,基本功能等几个方面作出了比较详细的介绍。系统中以iTrax02GPS接收机得到当前的地理位置信息,JPEG232作为现场实时图像采集模块,ARM2200作为车载移动终端的核心处理芯片,采用串口扩展技术,通过GPRS模块H7710作为移动终端目标的定位及图像信息传输模块,设计了车载移动终端。在监控中心的设计上,采用VC++作为开发环境,介绍并利用MapX作为地理信息系统进行二次开发。采用多线程技术建立TCP服务器对移动目标发送的信息进行监听。实现了移动目标在电子地图和图像模块上的实时显示。通过系统和Oracle数据库的连接,可以将移动目标的各种信息在数据库中进行存取,实现移动目标任一时间段内事件的回放功能。本系统实现了一个多技术融合的移动目标定位及图像监控系统,经过系统的测试,可以对车辆的监控起到良好的作用。更多还原

【Abstract】 With the rapid development of geography information system(GIS)in recent years,the supervision system based on GIS becomes an important measure to carry on the reasonable dispatch and safety management to kinds of transportation vehicles in the transportation and communication.However,it cannot satify monitor people to monitor real-time object observation.At the same time,the mobile video supervision is the one of important research way,it is also widely apply in the safety management and command fields because of its visualization behaviour.Therefore, with the continuous advancement of global cities’ modernization,traffic transportation is paid to more and more complicated.The system which not only can get monitor object’s geographical position but also catch real-time video supervision information is obiously nescessary.We should intergrate the orientation,image,telcommunication,map and database technologies into the communication and transportation system,which has the practical significance to orientation on the vehicle moving targets and real-time video.In this paper,geographical position information of vehicle moving object is acquisited by the global positioning system(GPS),and then the video collection card catches the scene’s image information.These position and image informations are transmitted by GPRS.Supervision is executed by plentiful geographical communication information of GIS and visual scene image.This system is designed by the database technology and used to the object data design method.In this paper,an application object and extension of the vehicle moving orientation and video supervision system is deeply researched.These aspacts range from system design target,design principle,total construct to basic function are particularly introduced.And in this paper,the three basic designs,total system consturct,teminal vehicle moving and monitor center,are detailed analyzed.In this case,iTrax02GPS is used to receive the current geographical poison information, JPEG232 is used to the model of scene image collectiong,ARM2200 is used as the key chip of the vehicle moving terminal,and serial port technology is adopted, GPRS module H7710 is used to orientate the moving terminal object and to tranmit image information.Therefore,the vehicle moving terminal is proposed.In the design of supervision center,VC++ is adopt to the development environment,and MapX is used to develop geography information system.The multithreading technology is proposed to set up the TCP server to monitor information from the moving object. The moving object can be realtime displayed on the electronic map and image module.The various moving object informations can be easily accessed by the database aider the supervision system and Oracle database connection.Therefore, playback function of the event of moving object at any time is realized.The result from the test is shown that the system has the good supvision to the vehicle.更多还原
