Design of Train Passenger Flow Monitoring System Based on BSSID Technology

In order to monitor the flow density of high-traffic area and realize the flow diversion from dense area to scattered area, a train passenger flow monitoring system based on basic service set identifier (BSSID) technology was developed. The system was composed of Java minicomputer, BSSID address detection program and background manager program. Taking advantage of Java minicomputer, the numbers of passengers around can be detected through the BSSID detection program, and using Redis cache and other technologies, the performance of the system can be improved. After uploading the data to the server, data integration and visualization were conducted on the server side. The practical result shows that this system can realize the monitoring and channeling of train passenger flow under the epidemic and normal conditions, which can provide a new possibility for the construction of modern intelligent subway and promote the development of subway informatization.
