Problems solved by technology

[0003] The above-mentioned existing electronic code scanning technology can scan and identify a small number of items in a short period of time, but when the number of items is relatively large, problems such as missing scans, failure to identify, or system malfunctions may occur
[0004] At present, there is no technical solution to scan the code to identify the labels of a large number of items in a short time

Embodiment Construction

[0033] The preferred embodiments of the present invention will be described in detail below.

[0034] The embodiment of the present invention can rely on a tag identification technology system (a smart school bag system based on RFID tag identification technology or a logistics warehouse management system based on RFID tag identification, etc.) Whether to respond is judged according to the information of the radio frequency signal.

[0035] The code scanning identification method for a large number of items in a short period of time in Embodiment 1 of the present invention, such as figure 1 As shown, its application scenario is that a reader (including a transmitter and a receiver) scans and identifies a large number of items.

[0036] Include the following steps:

[0037] Step S01, establishing a set, which is used to store tag codes and / or tag feature values;

[0038] Step S02, the reader sends a radio frequency signal, and the radio frequency signal contains collection i...

Abstract

The invention discloses a code scanning identification method and system for a large number of articles in a short time. The method comprises the following steps that: a set is established; a reader sends a radio frequency signal, wherein the radio frequency signal comprises set information; after receiving the radio frequency signal, the tag carried by the article judges whether the tag is in theset, if so, the tag does not respond, otherwise, the tag generates a response code and sends the response code to the reader; the tags identified by the reader are added to a set; and whether an ending condition is met or not is judged, if so, it is judged that code scanning is ended and the article corresponding to the tag in the set is the identified article, and if not, returning. According tothe method and the system, the technical problem of how to scan codes to identify tags of a large number of articles in a short time is solved.

Description

technical field [0001] The invention belongs to the technical field of electronic identification, in particular to a code scanning identification method and system for a large number of items in a short period of time. Background technique [0002] Electronic code scanning technologies such as barcode recognition technology and RFID tag recognition technology are non-contact target object recognition and tracking technologies, which are widely used in many fields such as life and production. Existing electronic code scanning technology, such as the document "Rui Fengge. RFID-based Intelligent Library Management System Design in Universities [J / OL]. China Science and Technology Information, 2019(15): 67-68+70[2019-09-09]" A RFID tag recognition technology based on the randomness algorithm of ALOHA (random competitive anti-collision algorithm) is proposed in the document "Luo Qian, Deng Chengzhong, Wang Jingmei, Yang Yong, Cui Zhirui. Digitalization of archives based on STM8S ...
