Abstract

The invention is suitable for the technical field of communication, and provides a wireless positioning method and device, and the method comprises the steps: broadcasting a range finding request frame to at least two positioning base stations for positioning when a positioning request is detected, and recording a first time stamp for transmitting the range finding request frame; receiving a replyranging frame returned by each positioning base station based on the request ranging frame, and recording a second timestamp of each reply ranging frame; based on the first timestamp, the second timestamp and the time difference, calculating a distance value between the positioning base station and a label sending the request ranging frame; and determining the position information of the label based on the base station information and the distance value. According to the above mode, the label can determine the position information of the label through one-time broadcasting and receiving of the reply ranging frames of the plurality of positioning base stations, the frequency of wireless communication is reduced, the positioning time is saved, and the power consumption of the positioning label is reduced.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a wireless positioning method and equipment. Background technique [0002] Wireless positioning system is a relatively common positioning system at present. A general wireless positioning system includes two parts: a positioning tag and a base station: the positioning tag is a mobile device installed on the target to be positioned; the base station is a device installed at a fixed location or on a track whose position can be calculated. [0003] In the existing wireless positioning system, the positioning tag periodically measures the distance from the ranging base station, and calculates the position of the positioning tag through the ranging value and the coordinates of the ranging base station. However, in the process of ranging, the distance measurement between a positioning tag and a base station generally needs to go through 3-4 wireless communications, a...
