基于BSSID技术的列车人流监测系统设计

为监控高人流量地区的人流密度并实现人流由密集区域至零散区域的疏导，开发一款基于基本服务集标识符（BSSID）技术的列车人流监控系统. 该系统由Java小型机、BSSID地址探测程序与后台管理程序等3部分组成. 系统利用Java小型机，通过BSSID探测程序对周围乘客数量进行探测，运用Redis缓存等技术提高性能，上传数据至服务端并进行整合及可视化处理. 实践证明，该系统可在疫情及正常情况下实现列车人流监控与疏导，为现代智慧地铁建设提供一种新的可能性，助推地铁信息化的发展.

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.
