基于车地无线的车载监控视频中心存储实现

Storage Implementation of Vehicle Monitoring Video Center Based on Vehicle-to-Ground Wireless

城市轨道交通车载视频监控系统由于受到车地无线传输带宽的瓶颈限制,难以实现在控制中心集中存储视频数据的需求,而随着近年来无线传输技术的发展,为解决这一问题提供了技术基础,本文介绍了目前在轨道交通行业中已使用的几种车地无线传输技术,就实现车载视频在控制中心存储提出可能的方案,并计算所需要的通信资源。

With bottleneck limits of wireless transmission bandwidth between vehicle and ground, it is difficult for vehicle-borne video surveillance system of urban rail transit to realize centralized storage of video data in control center. Development of wireless transmission technology in recent years provides technical basis to solve this problem. The paper introduces several vehicle-to-ground wireless transmission technologies applied in rail transit industry, and proposes possible solutions to realize storage of vehicle-borne video in control center, and calculates required communication resources.
