For the video monitoring system software platform developed by FOBOM Co., Ltd. for the subway, the subway is operated in a relatively narrow and closed underground space with dense personnel, belonging to the sensitive area vulnerable to attack and destruction. The public security image monitoring system is an important means to effectively protect the safety of the subway.  According to the characteristics of subway operation management, the train management personnel can be divided into the station level and the operation control center level.  So the subway operation monitoring system can be divided into station monitoring subsystem, train monitoring subsystem and control center monitoring subsystem.  In the station-level monitoring system, a number of cameras are set in the station platform and station hall area to monitor the train operation and passengers ' up and down.

In addition to the station attendants, the purpose of train driver monitoring is to understand the passengers on the corresponding platform.  The sub-monitoring system at the level of the control center mainly provides the dispatchers of the control center with the monitoring of the stations on the whole line, so that they can understand the train operation and passenger flow within the station in real time, so as to better carry out the train dispatching and operation organization management.  Through the monitoring of the train entering and leaving the station and the passengers on and off the station, and through the monitoring of the passenger flow in the station area, the dispatcher can understand the passenger flow and train operation of the station, so as to realize the purpose of dispatcher monitoring.  In addition, when a disaster occurs at the station, the video monitoring system can be used as a command tool for disaster prevention dispatchers to command emergency.
