针对客运/货运车辆的车载无线视频监控系统是车联网技术的一个发展方向,通过该系统,除了可以监控车辆的移动轨迹和运行情况外,还能够实时获取车内以及道路的音视频信息,对公交客运、交通管理、运政执法、银行押运等行业的支持尤为重要。针对移动多媒体数据流的传输问题从传输效率和传输质量这两方面进行了分析,介绍了一种车辆视频监控系统的组织架构,并针对设计要点进行了阐述。
Vehicle wireless video surveillance system for passenger / freight vehicles is a development direction of the vehicle networking technology. In addition to monitoring the movement trajectory and operation of the vehicle, the system can also obtain audio and video information of vehicles and roads in real time. Bus passenger transport, traffic management, transport law enforcement, bank escort and other industries support is particularly important. The transmission problem of mobile multimedia data stream is analyzed from the aspects of transmission efficiency and transmission quality. An organization structure of vehicle video monitoring system is introduced and the design essentials are described.
