METHOD OF SYNCHRONIZING SIGNALS IN UWB HIGH-PRECISION POSITIONING SYSTEM, AND SYSTEM

WIPO Patent Application WO/2017/167306

A1

The invention discloses a method of synchronizing signals in a UWB high-precision positioning system, and a system. The method comprises the following steps: (a) constructing a signal synchronization platform comprising a synchronization controller and N base stations configured to perform UWB high-precision positioning, wherein the synchronization controller is connected via a wired transmission medium to a receiver of a first base station, and the base stations are connected in cascade to one another; (b) sequentially receiving and forwarding, by each of the base stations, a clock synchronization signal transmitted by a synchronization generation device in the synchronization controller, and resetting, by each of the base stations, a high-precision clock thereof; (c) after receiving a UWB positioning code, recording, by each of the base stations, a present clock time at the high-precision clock of each of the base stations to obtain a time delay between any two of the base stations; and (d) employing the time delay as a correction quantity added into time information of a corresponding base station, so as to implement timing synchronization for all the base stations. The method is used to implement precision time synchronization of signals between base stations.
