长途客车视频监控系统的设计与实现

Design and Implementation of 3G Video Monitoring System on Long-distance Bus

以移动视频监控为出发点,结合音视频编解码技术、GPS卫星定位、3G无线网络传输等技术,实现对长途客车的实时定位和视频监控。利用无线摄像机、拾音器等车载前端设备进行音视频信息采集,存储在本地磁盘或通过无线网络上传。客车配备自动报警装置,以便报警信息及抓取的图像能够上传至监控中心及时处理。利用集成了语音模块的车载显示屏,实现行车安全提醒。通过内置GPS模块的车载主机,有效节约3G流量。

An effective system based on wireless video monitoring, audio and video decoding, GPS position and 3G network transmission is designed, thus to implement real-time location and monitoring of the long-distance bus. The vehicle wireless camera, pick-up device and other front-end equipments collect the video and audio information, store the information in the local disk or up-load through 3G wireless network. With auto-alert device, the alarming information is transferred to the monitoring center for real-time processing. With integrated terminal host and display device, the timely warning of driving security and the efficient saving of 36 flow could be realized.
