As China's rapid economic development, personnel and transport to a sharp increase in the number, the urban public transport situation deteriorating, an unexpected event is raised serious car crashes, especially in large and medium-sized cities such as Beijing, Shanghai, etc.
National major and medium-sized cities have choice URT building to mitigate the growing pressure on public transport, improve the core competitiveness of cities. Since the rail passenger traffic-intensive, complex, factors such as the number of active objects, require an emergency command monitoring system to ensure its safe and stable operation, video monitoring systems can play a prior analysis, judgement, ex post facto evidence has been assisting public safety departments to combat crime, maintaining social stability of an important means.Rail transit construction industry you attach great importance to the construction of a video surveillance system, video surveillance system at different stages of development, using the best combination of rail transit industry monitoring system construction; however the presence of the Metro-builders of a new question is: how to meet the new phase of the Metro monitoring needs.
As the pressure of urban transport, urban rail transport development gradually into a mesh, a city in just 1 line, 2 lines of the building, planning, traditional railway video monitoring building if you only consider the line of the situation will be the formation of islands of video surveillance, later to be islands of Unicom, potential will be faced with this dilemma: to adopt traditional analog access can only view the requirements met; second, the whole network Internet mutual control is bound to face how existing monitoring system in question.
In rail transport video surveillance system for planning, building, apart from considering the current building, you have to consider future monitoring of networking applications, where the total rail traffic control centre to be able to transfer all TCC front-end monitoring in real time, historical images.
This article on the construction of the subway control patterns and trends, analysis of Metro construction of traditional supervisory deficiencies as well as the subway all-IP video surveillance solution brings technology a revolutionary change, hope to find more affordable, improved rail transit construction industry monitoring system solutions.
All-IP technology has become a trend
Metro video surveillance is mainly related to the region: stations, train depots, car parks, consolidated base, main substation (the), operational control centre.
Traditional monitoring module combines the construction of the programme, local analog matrix construction, the use of hard disk recorders for storage while uploading through the encoder to a monitoring Center for unified monitoring.
This traditional way of CCTV applications in earlier subway lines such as Beijing, Shanghai, Guangzhou and other old line monitoring, a line of video stream generally not more than 300 road, belongs to the smaller monitoring system, with the station monitoring, each station only upload 8 road to the monitoring center, lack of global atmosphere watch, unified management, global control and other features.However, because this kind of traditional construction patterns in centralized monitoring, resources allocation, emergencies and more real-time transfer see, cross-line-see the image, save time, image storage, security, system maintenance, features easy extensibility, etc., have been very difficult to meet the needs of development.
So in today's rail industry video surveillance applications, CCTV IP solutions has become a trend.The reason is that, as China's rail transit construction of leaps, many cities have more than one of metro lines, the cross-line operations become industry development needs.
On the video monitor, when an emergency arises, how to cross-line access to image, appeared in a joint analysis of judgement becomes critical. IP monitoring at the beginning of the planning considerations to the unified image storage management needs, can be transferred at each line flexibility of historical images. Also, you can build the station monitoring and control system and control centre, in the event of an emergency event, Metro network-monitoring system for real-time understanding of the situation, global knowledge around human resources focus on the mobilization and management functionality.[1] [2] [3]
