Beschreibung
Zusammenfassung:	The invention discloses a Wifi-based position fingerprint positioning method. The method specifically comprises the following steps of S1, setting wireless Wifi hotspots; S2, performing data interaction; S3, acquiring a position fingerprint; and S4, acquiring a position change track. In the step fo setting the wireless wifi hotspots, at least more than three wireless Wifi hotspots (2.4 G and 5G double frequencies) are arranged. The installation position is based on covering the whole field, uniform distribution is realized as much as possible, wireless interaction data (including data such asan equipment identifier Mac address, a timestamp and signal strength) between all Wifi terminals in a field and the hotspot is acquired through the wireless hotspots; a mobile terminal calls a systemAPI by installing a sampling APP to collect surrounding deployed AP MAC addresses, signal strength RSSI and SSID information; and meanwhile, the current timestamp is attached and sent to the positioning server, and the mobile
