Abstract

The invention discloses a UWB-based device following method, device and system, and relates to the technical field of computers. One embodiment of the method comprises the steps of: obtaining an identifier of a UWB following unit, combining identification association record of a predetermined UWB following unit and a UWB wearing unit, and determining the UWB wearing unit associated with the UWB following unit; according to the identifiers of the UWB following unit and the UWB wearing unit, obtaining current coordinate values of the UWB following unit and the UWB wearing unit to determine a distance of the UWB following unit and the UWB wearing unit; and if the distance exceeds a predetermined distance threshold value, transmitting an acceleration command to a rolling unit associated with the UWB following unit to drive the roller of the rolling unit for accelerated rolling. According to the embodiment mode, a following device is bound on a luggage box to achieve automatic following ofthe luggage in a public place so as to effectively avoid the condition of collision and disengagement of the luggage.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a device following method, device and system based on UWB (Ultra Wideband, carrierless communication technology). Background technique [0002] Suitcase is an essential device for people to travel. With the intelligent development of life products, the concept of intelligence following the suitcase came into being. Currently, luggage tracking currently on the market mainly uses algorithms for human body biometric identification (for example, camera image recognition) and infrared detection (for example, laser scanning of human body outlines) to track and walk the follower. [0003] In the process of realizing the present invention, the inventor finds that there are at least the following problems in the prior art: [0004] 1) Different followers have different body characteristics and walking styles, so it takes a learning and calculation process to let the following d...
