摘要
Abstract
This paper takes the project sites of Changchun urban rail transit as an example,and takes the existing technical scheme for high-definition and standard-definition mixing and the operation status of existing equipment into consideration.This research makes comprehensive analysis of the current video storage technology,and makes reasonable use of hard disk resources,to analyze and compare the retrofitting contents and schemes for capacity expansion,and provide a detailed description of the retrofitting ideas for storage capacity expansion.The proposed solution solves the problem that the current video storage time does not reach 90 days,while maximizing the usage of the existing equipment,and saving the investment in the whole system.This research aims to provide ideas for similar retrofitting projects of existing rail transit lines.关键词
