Rail transit security system

At present, urban development is inseparable from rail transit, and the safety of rail transit is inseparable from security. On the whole, the safety system of rail transit safety and traditional areas is similar. The difference is that the monitoring points of the track security system are relatively scattered and the length of the line required for monitoring. In terms of system construction, it mainly includes passenger and freight stations, railways along the railway, bridge tunnels, and carriages.

Technological innovation

Frequent disasters continue to remind people to find an effective solution. The wireless transmission based on the public network can solve these problems well, and has been favored by many engineering integrators and Party A. The mobile video surveillance system is mainly installed on the locomotive and the car, and monitors the surrounding environment and the cabin environment in front of the train. The working principle is to digitally compress the video information collected by the front-end installed analog camera, and then transmit the compressed video image file to the nearest mobile base station point through the wireless video transmitter, and the monitoring center accesses the public network. The computer can be remotely monitored.
Intelligent analysis takes heat

The intelligent video analysis system has four main functions in the station security system: one is transportation management: the intelligent video analysis system installed in the car compartment can observe the dynamics of the whole train compartment through the monitoring terminal set in the broadcasting room, when an accident occurs. At the time, instructions are issued through the car broadcast system. The second is public security management: through the camera installed in the car to check the dynamics of the passengers in the car, and make intelligent analysis of the behavior of suspects. The third is information management: With the high integration of the system, more and more information needs to be processed by the monitoring terminal. The intelligent video analysis system can filter various information and save system resources. The fourth is environmental management: through the monitoring of the railway along the line, set and analyze the relevant data, play a role of early warning and early judgment.

From the product point of view, the railway security system monitoring equipment mainly uses fastball and low-illumination, high-line cameras. The fastball mainly installs the station hall, the station square, the freight station, etc., so that the crowds are dense. And the area can also provide a clear monitoring effect; in the ticketing window, station entrances and exits, bridges, switches, crossings, tunnels, unattended substations and lighting, etc., the open-air places with relatively large changes in day and night brightness are generally selected for low illumination and high number of lines. Infrared camera with dustproof, antifreeze, explosion-proof shield and heat sink.

Alarm equipment mainly includes: active infrared, passive infrared, vibration cable and emergency alarm. Active infrared alarms mainly select some products with infrared radiation function, installed on the perimeter wall of the station and some key areas such as warehouses. Once an exception occurs, an alert is automatically issued. Important areas such as station dispatching centers and high-tech management departments, in view of the unification of safety and aesthetics, will also use access control identification systems.
