Problems solved by technology

Existing UWB indoor positioning technologies include TOF positioning, TDOA positioning, etc. Each positioning technology requires certain wireless communication interaction. For high-precision real-time positioning systems, the real-time and stability of the system are very important, while the existing UWB indoor positioning technology, low system capacity, poor communication anti-interference performance, poor real-time performance of the system, does not meet the positioning requirements of large-capacity personnel and objects, and is not conducive to real-time and stable operation when large-capacity installed

Embodiment 1

[0073] Such as figure 1 with 5 Shown, the UWB indoor positioning method based on time division multiple access of the present invention, comprises the steps:

[0074] Step 1, set in the positioning area base stations ,in ;

[0075] Step 2, Terminal Request to enter the time synchronization network after entering the positioning area, and transmit a UWB signal once after entering the request, and record the sending timestamp in the time synchronization network ;

[0076] Step 3, base stations respectively received by the terminal After transmitting the UWB signal, record the received time stamp in the time synchronization network ;

[0077] Step 4, choose a base station As the central base station, the remaining base stations As a positioning base station, transmit a UWB signal through the selected central base station, and record the sending time stamp in the time synchronization network ;

[0078] Step 5, after all the positioning base stations in t...

Abstract

The invention discloses a UWB indoor positioning method based on time division multiple access. The steps include: setting N base stations BS in the positioning area i ;The terminal MS transmits a UWB signal and records the sending time stamp T MST ; base station BS i Record the receiving time stamp T after receiving the UWB signal BSR1(i) ; The central base station transmits a UWB signal and records the sending time stamp T BST ; After the positioning base station receives the UWB signal, record the receiving time stamp T BSR2(i) ; Parameters to build a positioning solution matrix to obtain the coordinates of the terminal MS. The UWB indoor positioning method utilizes N base stations BS i The combined positioning can effectively enhance the positioning accuracy of the terminal MS and realize the load balance of the base station; the terminal MS is positioned through the TDOA positioning method by using two UWB signal transmissions, which reduces the deployment cost of the UWB indoor positioning system.

Description

technical field [0001] The invention relates to a UWB indoor positioning method, in particular to a UWB indoor positioning method based on time division multiple access. Background technique [0002] UWB ultra-wideband technology is very different from traditional communication technology. It does not need to use the carrier in the traditional communication system, but transmits data by sending and receiving extremely narrow pulses with nanoseconds or less, so it has GHz magnitude of bandwidth. UWB indoor positioning can be used for indoor precise positioning and navigation in various fields, including people and large objects, such as valuables storage, mine personnel positioning, robot motion tracking, car basement parking, etc. [0003] Taking personnel positioning and object positioning as an example, in the prior art, UWB mobile devices are worn or fixed on people and objects, and at least 3 base stations are set up in the positioning area, and the calculation method o...
