Methods and systems for high density RFID part scanning

Abstract

A method for high density radio frequency identifier (RFID) scanning is provided. The method includes receiving a plurality of response signals from a plurality of RFID components. Where each of the plurality of response signals includes a part number and a serial number associated with the RFID component. The method also includes receiving, from a location device, a location of the scanning device. For each of the plurality of RFID components, the method includes determining a component location, the serial number, and the part number based on a corresponding response signal, comparing the component location to an expected location of the RFID component, determining a level of correlation between the serial number associated with the corresponding response signal and a stored serial number associated with the part number, and calculating a confidence score based on the corresponding comparison and the level of correlation.

Description

BACKGROUND[0001]The field of the invention relates generally to high density radio frequency identifier (RFID) part scanning, and more specifically, to scanning and identifying a plurality of closely located parts based on RFID tags.[0002]Known RFID systems utilize RFID readers and RFID tags. The RFID reader interrogates an RFID tag by transmitting a radio signal to the tag and receiving a response radio signal from the tag. The radio response signal may include information about an object to which the RFID tag is attached. Accordingly, by interrogating a plurality of RFID tags, information about a plurality of objects can be retrieved relatively quickly.[0003]However, depending on a location of the RFID tag and / or RFID reader, different power levels may be needed to detect different RFID tags. At least some known RFID readers allow a user to manually change the power level until an RFID tag is detected. However, using such a trial and error process to detect RFID tags may be time-c...

AI Technical Summary

Benefits of technology

The system enables efficient and reliable identification of RFID components in high-density areas by reducing the need for manual checks and minimizing errors, improving scanning efficiency and accuracy.

Problems solved by technology

However, using such a trial and error process to detect RFID tags may be time-consuming, and may result in missing (i.e., not detecting) one or more RFID tags.

However, manually checking items, such as safety equipment and / or maintenance equipment, generally is more time-consuming and / or labor-intensive.

Further, manually checking items may result in human error, making manual checks limited in their reliability.

In the known systems, detecting singular RFID tags requires an individual read per part, which can be very time consuming.

However, in some vehicles, some areas include a high density of parts with RFID tags.

These conditions may cause a frequency multi-path situation, which may make selecting individual tags difficult and increase the difficulty of adjusting the RF scanning window to capture just one tag at a time.
