Embodiment 1

[0026] see figure 1 , figure 1 It is the implementation flowchart of the multi-terminal indoor positioning method based on 5G signal in the embodiment of the present invention, combined with figure 1 It can be obtained that a 5G signal-based multi-terminal indoor positioning method of the present invention includes:

[0027] Step S101: At the first moment, establish a positioning coordinate system based on the three positions corresponding to the three user terminals using 5G signals in the designated indoor area, one of which is the target user terminal (the user terminal can be a mobile phone or other terminal) , the location corresponding to the target user terminal is the target initial location. Among them, among the three locations, one location is used as the center point, and the other two locations are used as reference points, and the number of user terminals using 5G signals around the center point is the most.

[0028] see figure 2 , figure 2 It is a schemat...

Embodiment 2

[0079] see Figure 4 , Figure 4 It is a partial structural frame diagram of the 5G signal-based multi-terminal indoor positioning device 100 according to the embodiment of the present invention, combined with Figure 4 It can be obtained that a 5G signal-based multi-terminal indoor positioning device 100 of the present invention includes:

[0080] The coordinate establishment module 110 is configured to establish a positioning coordinate system at the first moment according to three positions corresponding to three user terminals using 5G signals in a designated indoor area, wherein one user terminal is a target user terminal, and the target user terminal The corresponding position is the target initial position.

[0081] The position calculation module 120 is configured to calculate, at a second moment, the distance between the target user terminal and the multiple other user terminals in the specified indoor area according to the target initial position and the distance b...

Embodiment 3

[0085] see Figure 5 ,refer to Figure 5 It can be seen that a computer-readable storage medium 10 in the embodiment of the present invention, the computer-readable storage medium 10, such as: ROM / RAM, magnetic disk, optical disk, etc., has a computer program 11 stored thereon, the described When the computer program 11 is executed, the multi-terminal indoor positioning method based on the 5G signal as described in the first embodiment is realized. Since the 5G signal-based multi-terminal indoor positioning method has been described in detail in Embodiment 1, the description will not be repeated here.

[0086] In the multi-terminal indoor positioning method based on 5G signals implemented in the embodiment of the present invention, at the first moment, a positioning coordinate system is established according to the three positions corresponding to the three user terminals using 5G signals in the designated indoor area, and one of the user terminals is the target user termina...

Abstract

The invention discloses a multi-terminal indoor positioning method and device based on 5G signals, wherein the positioning method includes: at the first moment, establishing positioning according to three positions corresponding to three user terminals using 5G signals in a designated indoor area A coordinate system, wherein one user terminal is a target user terminal, and the position corresponding to the target user terminal is the target initial position; at the second moment, according to the target initial position and the distance between the target user terminal and multiple other user terminals in the designated indoor area , calculate the end position of the target user terminal at the second moment and in the positioning coordinate system; convert the target user terminal at the second moment and the end position of the positioning coordinate system into the target user terminal at the second moment and at the specified Physical location within the indoor area. The present invention can realize high-precision positioning indoors without installing special positioning base stations and purchasing special positioning tags.

Description

technical field [0001] The present invention relates to the technical field of indoor positioning applications, in particular to a multi-terminal indoor positioning method and device based on 5G signals. Background technique [0002] At present, the popularization of smart phones has made people more and more dependent on mobile phones, especially the services that mobile phones are expected to provide precise positioning have been significantly improved, but mobile phone precise positioning services cannot be realized in scenarios such as shopping malls, hospitals and underground parking lots. In addition, existing global satellite navigation systems such as GPS, Beidou, GLONASS, and Galileo cannot provide high-precision positioning indoors. New positioning technologies such as 5G networks are needed to achieve high-precision indoor positioning. Current indoor positioning technologies include WiFi positioning, ultra-wideband (UWB) positioning, and ultrasonic positioning, et...
