浅析地铁数字视频系统中的多级架构

Multi-level Architecture in Metro Digital Video System

对地铁安全防范系统中的视频监控子系统结构单一架构和多级架构进行比较;采用多级架构有利于构建稳定可靠的城市地铁监控系统,是整体联网联调的最佳解决方案;对数字视频系统多级系统架构关键技术进行详细描述。

A comparison of single-tier architecture and multiple-tier architecture of the video surveillance subsystem of the subway security systems is made. Adopting multiple-tier architecture is conducive to building a stable and reliable monitoring system of city subway and can serve as a optimum solution for the joint testing of the whole network. In the end, the key technologies of multiple-tier system architecture is described in detail.
