摘　　要：针对新一代无线车辆监控系统需要传输车辆定位和视频等宽带信息的需求,使用具有宽带传输能力的3G移动通信网络传输;介绍了监控系统的总体设计方案,并着重分析了车载移动监控终端的硬件结构、软件设计、视频的编解码标准、信息传输方案;系统视频方案由于采用了具有我国独立知识产权的AVS标准,规避了国际专利追偿风险,同时,3G网络的传输能力确保了监控质量;试验表明,系统能实现最大分辨率为VGA的动态视频监控,车辆定位精度?10m。New generation wireless--mode vehicle surveillance systems need to transmit wide--band information, such as positioning, video, a vehicle surveillance system based on 3G （3rd Generation Mobile System） network was designed. This paper introduced the general architecture of this system, and mainly analyzed the hardware structure and software design of the mobile surveillance terminal, and gave its scheme of video codec and information transmission. Because this system adopts AVS standard that China owns unique intellectual property, it avoids the risk compensated by international patents. The transmission ability of 3G can obtain guaranteed quality of surveillance. Main ex- perimental results as follow： Max resolution of moving video is VGA, accuracy of positioning ≤ 10m.
