Abstract

The invention relates to an article positioning method, comprising: using a reader to scan and read the labels set on the article along the storage shelf, recording the currently scanned shelf number and layer number, and collecting the label number and Signal strength; preprocess the data, divide the data with the same label number into a set, for a set, divide the data with the same scanning frame number and layer number into a group, and count the labels in the corresponding scanning frame number and layer number Reading frequency and average signal strength; take the reading frequency and average signal strength as the input of the fuzzy reasoning system, output the probability that the label is in the corresponding shelf number and floor number, and select the shelf number and floor number corresponding to the highest probability as the shelf number of the item and the layer number; further based on the Bayesian probability model, the sequence number of the item in the layer is obtained. This method is based on high-frequency RFID, and uses fuzzy reasoning system and Bayesian probability model to realize the precise positioning of items and improve the efficiency of staff inventorying items.

Description

technical field [0001] The invention relates to the field of radio frequency identification (RFID), in particular to a high-frequency RFID-based article positioning method and device. Background technique [0002] Radio frequency identification technology (Radio Frequency Identification, RFID), conducts non-contact two-way data communication through radio frequency, and uses radio frequency to read and write recording media (electronic tags or radio frequency cards), so as to achieve the purpose of identification and data exchange. Widely used in access control, parking lot control, production line automation, material management and other fields. [0003] According to different operating frequencies, RFID tags can be divided into different types such as low frequency, high frequency, ultra high frequency and microwave. The working principle of RFID in different frequency bands is different. RFID electronic tags in low frequency and high frequency bands generally adopt the ...
