【摘要】：当汽车在行驶过程中,发生一般类型的交通事故时,传统的事故处理方式需要等待交警来进行交通事故处理鉴定且保险勘查定损后双方车才能离开。这样不仅会导致交通拥堵,而且还会妨碍其他车辆正常通行甚至会引发其他突发事故,故要对发生一般类型的交通事故处理和理赔方式进行改进。所以,本文设计的目的是运用现代电子网络通信技术设计行车事故现场视频传输与管理系统来实现交通事故现场视频文件的远程传输和鉴定,意义在于既有利于缓解因发生一般类型或较小交通事故纠纷而引发的交通拥堵,又能提高交警和保险理赔部门的工作效率。在客户端的车载硬件平台中,采用ARM11架构的开发板并且用S3C6410处理器作为控制中心,构成视频传输与管理系统传输视频文件的发送端,完成视频文件传输的发送功能。采用带有3G无线网卡的华为E261 WCDMA模块连接3G无线网络,完成无线网络视频传输功能。采用H.264视频编码标准,将从行车记录仪当中读取到的视频文件压缩到开发板中,实现视频文件大小被压缩后变小,使传输速度快的功能。在服务端,采用PC机作为接收端,将带有3G无线网卡的华为E261 WCDMA模块,通过USB接口连接到PC机上,构成视频传输与管理系统的接收端,完成视频文件传输的接收功能。在客户端和服务端之间,采用3G无线网络进行连接,构成一个完整的视频传输与管理系统,实现对行车事故现场进行无线视频传输与信息反馈功能。采用Qt跨平台图形用户界面应用程序开发框架,编写视频传输与管理系统的发送端和接收端用户应用界面,实现视频传输的管理系统功能。采用实物连接的方法,对系统整体进行实验测试。系统实验测试表明,本系统可以实现对现场视频的文件传输与信息反馈,将两分钟的行车记录仪视频文件进行读取发送,结果为丢包率小并且播放质量效果良好,故可以达到系统的预期设计目标。
[Abstract]:When there is a general type of traffic accident in the course of driving, the traditional accident handling method needs to wait for the traffic police to deal with the traffic accident identification and the two cars can leave after the insurance investigation and fixed damage. This will not only lead to traffic congestion, It will also hinder the normal passage of other vehicles and even lead to other sudden accidents. Therefore, it is necessary to improve the handling and settlement of general types of traffic accidents. The purpose of this paper is to design a video transmission and management system for traffic accident scene by using modern electronic network communication technology to realize the remote transmission and identification of traffic accident scene video files. The significance is that it can not only alleviate the traffic congestion caused by the common type or minor traffic accident dispute, but also improve the efficiency of traffic police and insurance claim department. Using the ARM11 architecture development board and S3C6410 processor as the control center, the video transmission and management system transmission video file sending end, Using the Huawei E261 WCDMA module with 3G wireless card to connect to 3G wireless network, complete the wireless network video transmission function. The video files read from the CarLog are compressed into the development board to realize the function that the video file size is compressed and the transmission speed is high. On the server side, the PC is used as the receiver. The Huawei E261 WCDMA module with 3G wireless network card is connected to the PC through the USB interface, which constitutes the receiving end of the video transmission and management system, and completes the receiving function of the video file transmission. A complete video transmission and management system is constructed by using 3G wireless network to realize the functions of wireless video transmission and information feedback on the scene of traffic accidents. The QT cross-platform graphical user interface application development framework is adopted. The user interface of the video transmission and management system is written to realize the function of the video transmission management system. The whole system is tested by the method of physical connection. The system can realize the file transmission and information feedback of the scene video, read and send the video file of the two-minute CarLog, the result is that the packet loss rate is small and the playing quality is good, so the expected design goal of the system can be achieved.
