Auxiliary UWB positioning method based on Internet of Things

Abstract

The invention discloses an auxiliary UWB positioning method based on the Internet of Things, and belongs to the technical field of UWB positioning, a plurality of base stations send search signals regularly, the timestamp for sending the search signals is set as a first timestamp, and the signal strength for sending the search signals is set as a first signal strength; setting the timestamps when the plurality of base stations receive the feedback signals as second timestamps, and setting the signal intensities when the plurality of base stations receive the feedback signals as second signal intensities; acquiring monitoring coefficients of the plurality of base stations according to the plurality of first timestamps, the plurality of second timestamps, the first signal strength and the second signal strength, and dynamically adjusting a main base station and an auxiliary base station in the plurality of base stations according to the monitoring coefficients; the method and the device are used for solving the technical problem of poor positioning accuracy caused by incapability of self-adaptive adjustment when communication signal transmission is interfered by external factors because a main base station and an auxiliary base station are not dynamically monitored and adjusted in the existing scheme.

Description

technical field [0001] The invention relates to the technical field of UWB positioning, more specifically, it relates to a method for assisting UWB positioning based on the Internet of Things. Background technique [0002] Most of the traditional UWB (UltraWideband) positioning technology installs multiple fixed micro base stations indoors to perform accurate indoor positioning on the same identification card in the same environment in real time, and displays the position of the identification card to the control center with zero delay to realize Real-time monitoring of the location of the identification card, but once the identification card moves or is blocked by obstacles, the identification card cannot be accurately positioned. [0003] The publication number is CN109633533A, and the name of the invention is a UWB high-precision positioning method. The UWB positioning signal receiver with a known position receives the positioning signal transmitted by the UWB positioning...
