example 1

[0101] This example provides a UWB device using multiple UWB antenna groups, where multiple UWB antenna groups in the UWB device share one UWB signal processing chip (corresponding to the aforementioned processing module). The coverage areas of multiple UWB antenna groups reach the entire spatial range.

[0102] The UWB device introduces a channel switch chip (corresponding to the aforementioned selection switch module). The number of UWB signal processing chips does not increase, but increases; at the same time, a channel switch chip for the antenna signal transmission link is added, which can control the selected The UWB antenna is connected to the UWB signal processing chip.

[0103] like Image 6 As shown, three UWB antenna groups are listed, using a triangular layout. The effective signal receiving range that each antenna can cover is 150 degrees. The three groups of antennas have an overlapping area of ​​30 degrees. The three groups of antennas can cover the entire spac...

Abstract

The embodiment of the invention discloses a positioning communication device, a positioning method and a computer storage medium. The positioning communication device includes: at least two positioning antenna groups, at least for receiving positioning signals sent by beacons, wherein the positioning antenna groups include two positioning antennas arranged separately, and the positioning antenna groups of different positioning antenna groups The positioning range is at least partially different; the selection switching module is respectively connected to the at least two positioning antenna groups; the processing module is connected to the positioning antenna group through the selection switching module, and is used to connect to the positioning antenna group according to the previous beacon. The location information at the moment controls the positioning antenna group that the selection switching module is turned on, and determines the location information of the beacon at the current moment according to the positioning signal received by the turned-on positioning antenna group.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a positioning communication device, a positioning method and a computer storage medium. Background technique [0002] With the continuous development of science and technology, communication positioning technology has been developed rapidly, especially Ultra Wide Band (Ultra Wide Band, UWB) carrier-free communication technology. UWB was used in short-distance high-speed data transmission in the early days. In recent years, it has begun to use its sub-nanosecond ultra-narrow pulse for short-distance precise positioning. [0003] UWB positioning has the characteristics of high precision, small size, low power consumption, etc., and has broad application prospects. Especially when a phase difference of arrival (Phase Difference of Arrival, PDOA) positioning algorithm based on signal angle of arrival is used for positioning, a higher positioning accuracy can be obtain...
