Method for determining location of item and mobile terminal

Abstract

An embodiment of the present invention provides a method for determining the location of an item and a mobile terminal. The method comprises a step of setting n positioning tags on a first plane of ashelf, receiving the coordinates of the n positioning tags, receiving a tag number of a tag to be searched, and obtaining a distance between the mobile terminal and the tag to be searched, wherein n is a positive integer greater than or equal to 3, a step of determining a radius of a circle with the coordinates of a projection point as a center on the first plane according to a vertical distance and the distance between the mobile terminal and the tag to be searched, transmitting a light beam, displaying a first aperture formed by the center and the radius of the circle on the first plane, wherein the tag to be searched is on the circumference of the first aperture, and a step of holding the light beam, moving the mobile terminal to the second coordinates, displaying a second aperture on the first plane, and determining a final position of an item corresponding to the tag to be searched according to a positional relationship between the first aperture and the second aperture. The positioning effect is more intuitive.

Description

technical field [0001] The invention relates to the field of data communication, in particular to a method for determining the position of an item and a mobile terminal. Background technique [0002] With the development of RFID technology in the Internet of Things, material management is increasingly shifting from barcode to RFID label management. For example, paper barcodes are attached to clothes, and they need to be sorted out one by one and scanned within the visible range, which is very inefficient, and it is easy to miss scanning, making it difficult to locate and search. Now there is an RFID solution, through a handheld (a mobile terminal) RFID reader, the RFID tag can be penetrated and scanned invisibly. It is used in scenarios such as asset inventory and finding items, which is very efficient. [0003] RFID: Radio Frequency Identification is a communication technology that can identify specific targets and read and write related data through radio signals without...

AI Technical Summary

Problems solved by technology

[0013] Analysis: First of all, this solution is costly to implement and requires multiple readers and reference tags. In order to match the actual approach position, the same number of reference tags as the checked tags are required in extreme cases (for example, if a shelf has 1000 small lockers, then Need 1000 reference tags to be pasted in front of the cabinet, and need about 10 readers)
