Classification: CPC G  H | IPC G  H

Claim 8:
9. A data interaction system, comprising: at least three Ultra-WideBand (UWB) positioning base stations and a mobile terminal, wherein
one of the at least three UWB positioning base stations is a reference positioning base station;
each of the UWB positioning base stations is configured to transmit a UWB positioning signal according to a preset period; and
the mobile terminal is configured to obtain the UWB positioning signals transmitted by the at least three UWB positioning base stations, and to determine a relative position of the mobile terminal with respect to the reference positioning base station according to the UWB positioning signals,
wherein the data interaction system further comprises: a UWB data base station, a background server, and a plurality of gates, wherein
the reference positioning base station is configured as a reference point for a coverage area covered by a gate among the plurality of gates;
the mobile terminal is further configured to: determine whether the mobile terminal is located in the coverage area of the gate according to the relative position; and in response to the mobile terminal being located in the coverage area of the gate, establish a data connection with a UWB data base station and perform data interaction with the background server through the data connection; and
the background server is configured to control the gate to open after the data interaction is completed,
wherein the data interaction system further comprises a communication module in a target communication mode, wherein
the communication module is configured to transmit a broadcast signal according to a preset target communication mode; and
the mobile terminal is further configured to scan the broadcast signal in the preset target communication mode, and to turn on a UWB receiver in the mobile terminal in response that the broadcast signal is detected,
wherein the target communication mode comprises at least one of WiFi communication and Bluetooth communication.
