I. Overview of intelligent rail transit video surveillance
As an important transportation hub in public places, the subway has very high mobility and a large number of people gather. The rail transit needs to use video surveillance system to achieve full and all-round security prevention, which is also an important means to ensure the organization and safety of subway running. Dispatchers and station duty officers can monitor train operation, passenger flow and equipment operation of substation equipment room through the system to improve the efficiency of traffic command. When an accident occurs in the station, the video surveillance system can be used as a powerful tool for the dispatcher to direct the emergency rescue.
Second, the solution
1. Program composition:
Video surveillance system: including front-end audio and video acquisition equipment, station and central control processing, network management equipment, monitoring terminals, etc. Intelligent video analysis technology: through the extraction of various feature information in video image data, automatic analysis and understanding of video image content and mutual relations, so as to achieve the structured description of the purpose of obtaining video image key information
2. Video convergence and monitoring system
EasVCVR security monitoring visual management system has been deployed in many places across the country, applied in a variety of offline scenarios and has many years of project operation experience. In the rail transit scene, the installation location of video surveillance involves the whole line station, car depot, train, parking lot, main substation, management room, exit population, ticket room and other links, video convergence/security monitoring/intelligent transportation EasVCVR platform can be in a complex network environment. The surveillance cameras, hard disk recorders and other devices deployed in each station and area of the subway are centrally accessed, aggregated and managed to realize real-time live broadcast of surveillance video, cloud video recording, video cloud storage, video storage disk array, video playback and retrieval, alarm reporting, video snapshot, video transcoding and distribution, and platform cascade for each area.
3. AI video intelligent analysis system
With the help of video AI intelligent analysis system, through real-time analysis of surveillance video images in metro internal and external public areas and other places, the target in the dynamic scene can be located, identified and tracked, and the behavior of the target can be analyzed and judge, so as to respond in time when abnormal situations occur, so as to achieve early detection and active prevention. Help security personnel to effectively avoid or efficiently deal with emergencies.
