Embodiment Construction

[0049] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0050] see figure 2 , which shows a schematic diagram of the composition of a positioning system capable of implementing an embodiment of the present invention. Note, figure 2 The illustrated system is but one example of a possible system, and embodiments of the present disclosure may be implemented in any of a variety of systems as desired.

[0051] like figure 2 As shown, the positioning system 100 includes: a PC (Personal Computer, personal computer) 10, a master base station 11, and one or more slave base stations. In the embodiment of the present invention, two slave base stations are taken as an example, which are respectively identified as slave base stations 12 and From base station 13, one or more of the above base stations are in the signal coverage ar...

Abstract

The embodiment of the invention discloses a BLE-UWB-based positioning scheduling method, device and system and a storage medium. The method may comprise the following steps: when a Bluetooth Low Energy (BLE) broadcast message sent by a slave device is scanned, establishing a BLE connection link with the slave device; configuration information transmitted by the background PC is sent to each slave device based on the BLE connection link; sending a synchronization message including synchronization information and time sequence distribution information to the slave base station and the UWB tag device; completing a ranging process with each of all UWB tag equipment in a ranging cycle allocated by the main base station for the main base station, and obtaining a ranging result of each UWB tag equipment; and receiving a distance measurement result of each slave base station for each UWB tag device, and uploading the distance measurement results of all base stations for each UWB tag device to a background PC.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of UWB communications, and in particular, to a BLE-UWB-based positioning and scheduling method, device, system, and storage medium. Background technique [0002] Ultra WideBand (UWB, Ultra WideBand) technology is a carrier-free communication technology that uses nanosecond to microsecond non-sinusoidal narrow pulses to transmit data, and can transmit extremely low-power signals over a wide spectrum. Therefore, UWB The technology is widely used in application scenarios such as data transmission, positioning and ranging. [0003] In the version number 802.15.4z protocol standard published by the Institute of Electrical and Electronics Engineers (IEEE, Institute of Electrical and Electronics Engineers), the process scheme of using UWB for ranging is described in detail, and a cluster tree-based (Cluster Tree ) structure networking mode, one of the networking examples that conform to the C...
