为了解决高效监控公交安全状况的热点问题,本文使用H.264视频压缩标准与实时流媒体协议RTSP,实现了监控视频的实时传输功能;并结合4G传输、GIS定位、FPGA电路设计等技术设计实现了一个集视频实时传输与车内预警、控制等功能于一体的公交监控系统.通过将系统在北京市公交线路上进行实际测试,验证了本系统可有效提高公交监控的工作效率与管理水平,具有视频建立时间短、视频画面清晰、播放流畅等特点.

英文摘要：

How to efficiently monitor the security situation in the bus is becoming an industry hotspot. To solve the problem,we use the H. 264 video compression standard and real-time streaming protocol（ RTSP） to achieve a real-time transmission of surveillance video. Combining with 4G transmission,GIS positioning,FPGA circuit design and other techniques,we design to achieve a bus video surveillance system which is a combination of real-time video transmission,early warning and control of vehicle and other functions. By placing the system on Beijing bus lines for the actual testing,this system is proved to effectively improve the work efficiency and management level of bus monitoring,with traits such as short video set-up time,clear video images,smooth playback and so on.
