Abstract

The invention provides a distance measurement method, device and system and a readable medium, and belongs to the technical field of distance measurement. The method comprises the steps of scanning aBluetooth signal broadcasted by a base station through a Bluetooth module; calculating a first distance between the beacon and the base station according to the Bluetooth signal, and judging whether the first distance is within a preset distance measurement range or not; wherein the preset ranging range is smaller than the ranging range of the UWB module; if the distance is within the preset distance measurement range, starting a UWB module; and calculating a second distance between the ranging terminal and the base station through the UWB module. The UWB module can be started only when the first distance is within the preset distance measurement range, the preset distance measurement range is smaller than the actual distance measurement range of the UWB module, and compared with the priorart that the UWB module needs to be started all the time, the number of UWB measurement times is reduced, and therefore power consumption is greatly reduced.

Description

technical field [0001] The present application relates to the technical field of ranging, and in particular to a ranging method, device, system and readable medium. Background technique [0002] At present, in the existing technology, in modern factories, forklifts are mainly used for material handling. When forklifts frequently transport materials back and forth, safety accidents between workers and forklifts are likely to occur. In order to ensure the effective safe distance between forklifts and workers, It is necessary to accurately and timely remind the forklift driver that there are pedestrians around within a certain safe distance, so it is necessary to measure the distance between the forklift and the staff. [0003] In the prior art, UWB (Ultra Wideband) technology is used for distance measurement. The distance measurement terminal carried by the staff needs to turn on the UWB function all the time, and measure the distance of the base stations installed on the fork...
