Article checking system and article checking and processing method and device

Abstract

The invention provides an article checking system and an article checking and processing method and device. The article checking system includes a photoelectric identification OEID reading-writing device arranged on a light source in a specified space and used for issuing query commands to OEID tags arranged on articles in the specified space according to light signals transmitted by the light source, identifying the articles according to uplink data fed back by the OEID tags and sending identification results to a monitoring terminal, the OEID tag for sending the uplink data to the OEID reading-writing device under the trigger of the query command, and the monitoring terminal for obtaining article checking results of the articles in the specified space according to the identification results. By the adoption of the technical scheme, high power consumption, large harm to human, limited working environment and the like existing in related arts and an RFID tag technology are solved, and a technology for reading and writing other tags capable working normally can be achieved in many cases.

Description

technical field [0001] The present invention relates to the communication field, in particular to an item counting system, an item counting processing method and a device. Background technique [0002] With the substantial increase in productivity in modern society, products and services are greatly enriched, especially for warehouse material management, which requires a new energy saving and fast inventory. For some offices, especially for archives, secret rooms, libraries, etc., there is a need for quick inventory of important items in the room. [0003] At present, the tag identification technology that can meet these requirements is (Radio Frequency Identification, referred to as RFID) technology, such as figure 1 shown. This is a point-to-multipoint (point 2 multiple point, referred to as P2MP) application scenario. RFID readers need to be installed at the entrance and exit. If the indoor space is large, the readers need larger antennas and higher power , which resul...

AI Technical Summary

Problems solved by technology

This is a point-to-multipoint (point 2 multiple point, referred to as P2MP) application scenario. RFID readers need to be installed at the entrance and exit. If the indoor space is large, the readers need larger antennas and higher power , which results in greater power consumption, and the reading and writing device must be turned on all the time, these radiations will have some impact on the human body

Since RFID uses wireless radio frequency for transmission, it also has some weaknesses of radio frequency, such as: it is sensitive to electromagnetic radiation places and metal devices, and cannot work normally. At the same time, due to the antenna, the RFID tag cannot be too small, so RFID Signs are restricted to work in many places

[0004] Aiming at the problems of high power consumption, large human injury and limited working environment in RFID tag technology in related technologies, no effective solution has been proposed
