摘要
The security of public places has been greatly concerned by the government and organizations in recent decades. Detecting the crowd flow in public places can help alerting the congestion of the channel immediately and making an immediate evacuation policy to prevent the occurrence of extrusion stampede. However, the common detection techniques require special additional hardware components that suffer from too many factors. This paper proposed a method of crowd flow detecting based on RFID by analyzing the factors affecting the RFID link state. The system composed of the RFID tag arrays and the reader which detects the pedestrian flow according to the counts and the RSSI value of reading RFID tag arrays. With the evaluation in different scenarios, the coverage and moving status of the crowd can be verified.
