POSITIONING DEVICE, POSITIONING SERVER, AND POSITIONING METHOD
Document Type and Number:
WIPO Patent Application WO/2022/217554
Kind Code:
A1
Abstract:
The present application provides a positioning device, a positioning server, and a positioning method. The positioning device comprises: a first positioning module for obtaining position information of the positioning device in real time; and an ultra wide-band (UWB) positioning module for receiving a positioning request message sent by a label to be positioned, the positioning request message comprising identifier information of said label; the UWB positioning module being further used for determining, after receiving the positioning request message, whether the UWB positioning module is in a UWB base station mode; and the UWB positioning module being further used for performing positioning measurement on said label in the UWB base station mode according to the position information and the identifier information. According to the technical solution, when the positioning precision of said label is reduced or the positioning interruption occurs due to insufficient quantity or distribution of fixed base stations around a UWB label to be positioned, a nearby UWB label base station is used as a positioning assisting base station, such that the high-precision positioning of said label and the continuity of positioning can be guaranteed.
