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 comprises at least two positioning antenna groups and at least one positioning signal for receiving a beacon transmission, wherein the positioning antenna group comprises two positioning antennas which are separated and arranged, andthe positioning ranges of different positioning antenna groups are at least partially different; a selection switching module which is respectively connected with the at least two positioning antennagroups. The positioning communication device also comprises a processing module which is connected with the positioning antenna group through the selection switching module. The processing module isused for controlling the positioning antenna group which is conducted by the selection switching module according to the orientation information of the first time of the beacon, and the orientation information of the current time of the beacon is determined according to the positioning signals received by the conductive 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...
