Abstract

The invention discloses a code scanning identification method and system for a large number of items in a short time. The method includes the following steps: establishing a collection; the reader sends a radio frequency signal, and the radio frequency signal contains collection information; after the tag carried by the article receives the radio frequency signal, it judges whether the tag is in the collection, if so, the tag does not respond; otherwise, the tag generates a response code and Send to the reader; add the tag identified by the reader to the collection; judge whether the end condition is satisfied, if so, judge that the code scanning is complete, and the item corresponding to the tag in the collection is the recognized item, otherwise return. The method and system of the present invention solve the technical problem of how to scan codes in a short time to identify labels of a large number of items.

Description

A method and system for scanning code identification for a large number of items in a short period of time technical field The invention belongs to the technical field of electronic identification, and particularly relates to a scanning code identification method for a large number of items in a short time. laws and systems. Background technique Electronic scanning code technology such as barcode identification technology, RFID tag identification technology is non-contact target object identification and Tracking technology has been widely used in many fields such as life and production. Existing electronic scanning technology, such as the document "Ruifengge. Design of University Intelligent Library Management System Based on RFID [J / OL]. China Science and Technology Information, 2019(15):67‑68+70[2019‑ 09‑09]", a RFID tag identification technology based on the randomness algorithm of ALOHA (random competition anti-collision algorithm) was proposed. Art, Literatu...
