Abstract

The embodiment of the invention discloses a UWB system positioning base station calibration method and a device thereof. The method comprises the following steps: acquiring the data transmission timeof the communication data transmitted between the target base station and the base station to be calibrated based on the UWB transmission channel in the UWB positioning system, and calculating the base station distance between the target base station and the base station to be calibrated according to the time and the data transmission rate; A target base station and a base station to be calibrateare obtained in a coordinate system with a current position environment as a reference, and calculating the coordinate distance between the real coordinate value of the target base station and the base station to be calibrated based on the azimuth angle of the reference coordinate system, and adjusting the real coordinate value to be calibrated according to the relationship between the coordinatedistance and the distance of the base station and the azimuth angle. By adopting the invention, the coordinate value of the base station to be calibrated measured manually is adjusted according to theaccurate distance between the target base station and the base station to be calibrated through accurately calibrating the coordinates of the target base station, the calibration precision of the base station can be improved, and the accuracy of the UWB positioning system can be further improved.

Description

technical field [0001] The invention relates to the technical field of wireless positioning, in particular to a method and equipment for calibrating a positioning base station of a UWB system. Background technique [0002] The current common wireless positioning technologies mainly include WIFI technology, infrared technology, ultrasonic positioning, ultra-wideband UWB positioning and Bluetooth positioning. Among them, UWB positioning technology is the one with the best comprehensive performance among the above-mentioned wireless positioning technologies. The UWB positioning system needs at least three positioning base stations and several positioning tags. Make a positioning basis. In the prior art, in order to reduce the cost of the positioning system, manual measurement is usually used to calibrate the positioning base station in the positioning scene, such as manually measuring and calibrating through a measuring ruler. However, the accuracy of the manually calibrated p...
