Abstract

The invention discloses a clock positioning method and device, a storage medium and a communication system. The method includes: determining the distance time difference between a master base stationand slave base stations; determining the arrival time difference of a beacon positioning signal arriving the slave base stations according to the distance time difference; determining the position ofa positioning beacon according to the arrival time difference to achieve TDOA wireless clock synchronous positioning. By the method, the problem of clock deviation accumulation caused by DW1000 clockdeviation and brought by wireless clock synchronization in a TDOA positioning method can be solved, and clock deviation accumulation can be inhibited.

Description

technical field [0001] The invention belongs to the field of communication technology, and in particular relates to a clock positioning method, device, storage medium and communication system, in particular to a UWB positioning TDOA algorithm wireless clock synchronous positioning clock deviation analysis and deviation elimination implementation algorithm, device and storage medium and communication systems. Background technique [0002] According to the characteristics and working mode of DW1000 (ultra-wideband wireless transceiver chip compatible with IEEE802.15.4-2011 protocol), UWB (Ultra Wideband) is a non-loaded communication Pulse transmission data) positioning can be divided into TWR (tow way ranging, two-way method) polling ranging positioning and TDOA (time difference of arrival, time difference of arrival) positioning of the time difference between arrival at the base station. The positioning principle of TWR polling is signal The standard will actively send a ra...
