Problems solved by technology

The UWB three-dimensional positioning technology currently in use requires at least four base stations, resulting in a large consumption of hardware resources, which has caused great resistance to the use of UWB technology with high equipment costs. Location is limited and communication takes too long

Embodiment Construction

[0065] In this embodiment, a three-dimensional positioning method for three base stations based on UWB technology is applied in a base station environment composed of a host computer and four base stations, wherein one base station is used as a tag; the tag to be tested is placed on the Carrier, and make it in the environment of 3 base stations, build a ranging system through base station screening; after the screening work is completed, establish a positioning coordinate system composed of three base stations and obtain the distance from the 3 base stations to the tag to construct a Corresponding tetrahedron; the positioning of the label is realized after obtaining the height of the label and the information of the horizontal and vertical coordinates through calculation. Specifically, proceed as follows:

[0066] Step 1. Base station screening:

[0067] Step 1.1. The three base stations try to communicate with the tag respectively. After the communication is established, the...

Abstract

The invention discloses a three-base station three-dimensional positioning method based on UWB technology. The steps include: 1. Put the tag to be tested on the carrier to be tested, and in the environment of three base stations, construct a ranging system through base station screening ; 2. Construct a three-dimensional positioning coordinate system based on three base stations; 3. Obtain the distance from the three base stations to the tag based on the three-dimensional positioning coordinate system; 4. Construct a tetrahedron based on the obtained distance information, and obtain the height and vertical and vertical dimensions of the tag Coordinate information to achieve positioning. The present invention can further improve the efficiency of UWB three-dimensional positioning, reduce hardware overhead and equipment cost, thereby improving the overall performance of the positioning method.

Description

technical field [0001] The invention belongs to the technical field of positioning and navigation, and specifically relates to a three-dimensional positioning method for three base stations based on UWB technology. Background technique [0002] With the development of modern science and technology, positioning technology has been widely used in various fields of society. Compared with the outdoor positioning technology that has penetrated into all aspects of our lives - global positioning technology, indoor positioning has not yet matured due to the constraints of positioning time, accuracy, environmental conditions and other factors; at the same time, future positioning The development trend of technology must be the combination of indoor positioning technology and outdoor positioning technology, so more and more people are beginning to study indoor positioning technology. [0003] Ultra Wide Band (UWB) positioning technology has the advantages of low power consumption, hi...
