High-precision positioning system

Abstract

The present invention is applicable to the field of sports equipment, and provides a high-precision positioning system, including: UWB positioning tags, used to transmit pulse radios; multiple positioning base stations, used to receive pulse radios transmitted by UWB positioning tags, and each positioning base station Determine the distance from the UWB positioning tag to the positioning base station according to the received pulse radio; the positioning server is used to determine the position information of the UWB positioning tag according to the distance from the UWB positioning tag to each positioning base station; and the map server receives the position information of the UWB positioning tag. , and display the location information of the UWB positioning tag on the map. Wherein, the overlapping coverage area of ​​multiple positioning base stations is provided with a positioning map area for positioning UWB positioning tags. A high-precision positioning system provided by the present invention uses a UWB positioning tag to transmit a pulse radio, and the positioning base station receives the pulse radio and then locates the UWB positioning tag, which can realize regional high-precision positioning, high positioning accuracy, and reliability Strong.

Description

technical field [0001] The invention belongs to the field of sports equipment, and in particular relates to a high-precision positioning system. Background technique [0002] With the development of the economy and the progress of society, sports have become an indispensable part of people's lives, and when people are doing sports, they often need to run, and then need to be positioned for detection, such as running, football Wait. [0003] However, most of the software and equipment for recording running on the market today, such as Gudong, use GPS technology for positioning and recording tracks. The GPS positioning accuracy range is 5-20m, and the running track in some occasions is often not recorded, such as the crossing event in football (requiring accuracy within 10cm); at the same time, the positioning equipment using GPS technology is in use. , It is greatly affected by the signal strength of the GPS positioning signal. Sometimes, the satellite signal will not be re...

Problems solved by technology

The GPS positioning accuracy range is 5-20m, and the running track in some occasions is often not recorded, such as the crossing event in football (requiring accuracy within 10cm); at the same time, the positioning equipment using GPS technology is in use. , is greatly affected by the signal strength of the GPS positioning signal. Sometimes, the satellite signal will not be received, and it is prone to poor positioning accuracy or positioning failure.
