Problems solved by technology

[0004] However, the current of UWB in the receiving state is relatively large, and if it is turned on for a long time, the power consumption will be large
At the same time, because UWB tags interfere with other UWB devices during the opening process, it is not possible to install too many UWB tags at the same time when using UWB positioning

Abstract

Embodiments of the present disclosure provide a positioning method and device based on dual-mode tags. The method includes acquiring broadcast information sent by multiple devices in low power consumption mode; determining a target device according to the broadcast information and making a wireless connection with the target device; sending positioning request instruction information to the target device and receiving information from A UWB message frame of the target device; locating the target device according to the UWB message frame. In this way, it is possible to reduce the UWB turn-on time during the device positioning process, reduce device power consumption and reduce interference to other UWB devices.

Description

technical field [0001] Embodiments of the present disclosure relate to the technical field of wireless positioning, and more specifically, to a dual-mode tag-based positioning method and device. Background technique [0002] In an open outdoor environment, accurate positioning can be obtained by relying on the GPS positioning system, but in an indoor environment, the GPS signal attenuation is serious, and the indoor environment is complex, there are various interferences and noises, and accurate positioning cannot be performed. [0003] At present, common indoor positioning technology solutions mainly include ultrasonic technology, Bluetooth technology, infrared technology, radio frequency identification technology, ultra-wideband technology (UWB) and wireless local area network. Among them, UWB has good anti-multipath effect, high security, low system complexity, good time resolution, and can provide centimeter-level positioning accuracy at the same time. It can be used for...
