Abstract
A data interaction method includes: acquiring UWB positioning signals transmitted by at least three UWB positioning base stations, where one of the at least three UWB positioning base stations is a reference positioning base station; and determining a relative position of the mobile terminal with respect to the reference positioning base station based on the UWB positioning signals.
Claims9
A data interaction method, the method being applied to a mobile terminal and comprising:
- acquiring Ultra-WideBand (UWB) positioning signals transmitted by at least three UWB positioning base stations, wherein one of the at least three UWB positioning base stations is a reference positioning base station;
- and
- determining a relative position of the mobile terminal with respect to the reference positioning base station according to the UWB positioning signals,
- wherein the reference positioning base station is configured as a reference point for a coverage area covered by a gate among a plurality of gates, and the method further comprises:
- determining whether the mobile terminal is located in the coverage area of the gate according to the relative position, and
- in response that the mobile terminal is located in the coverage area of the gate, establishing a data connection with a UWB data base station and performing data interaction through the data connection, such that the gate is controlled to open;
- and
- the method further comprises:
- scanning a broadcast signal in a preset target communication mode, wherein the target communication mode comprises at least one of WiFi communication and Bluetooth communication, and
- turning on a UWB receiver in the mobile terminal in response that the broadcast signal is detected.
