RFID tag reader, RFID tag reading system, method for performing RFID tag reading process and computer-readable recording medium
First Claim
1. An RFID tag reader comprising:
- a signal intensity obtaining part configured to obtain signal intensities of a plurality of RFID tags that are read at plural read processes;
a read-quantity obtaining part configured to obtain the quantity of the RFID tags read at each of the plural read processes;
a processing part configured to weight the signal intensities of the plurality of RFID tags in a manner that the greater the quantity of the RFID tags, the greater the signal intensity is weighted and that the smaller the quantity of the RFID tags, the less the signal intensity is weighted; and
a selecting part configured to select a target RFID tag from the plurality of RFID tags, the target RFID tag having a signal intensity weighted by the processing part, wherein the signal intensity of the target RFID tag is greater than a designated value.

Abstract
An RFID tag reader is disclosed that includes a signal intensity obtaining part configured to obtain signal intensities of a first RFID tag and a second RFID tag that are read at plural read processes, a read-number obtaining part configured to obtain a number of RFID tags, among the first and the second RFID tags, that are read at the same read process, a processing part configured to weight the signal intensity of the first RFID tag obtained by the signal intensity obtaining part based on the number obtained at the corresponding read process, and a selecting part configured to select a read result of the first RFID tag based on the signal intensity of the first RFID tag weighted by the processing part.

7. A method for performing RFID tag reading process comprising:
-
first obtaining signal intensities of a plurality of RFID tags that are read at plural read processes; second obtaining the quantity of the RFID tags read at each of the plural read processes; weighting the signal intensities of the plurality of RFID tags in a manner that the greater the quantity of the RFID tags, the greater the signal intensity is weighted and that the smaller the quantity of the RFID tags, the less the signal intensity is weighted; and selecting a target RFID tag from the plurality of RFID tags, the target RFID tag having a signal intensity weighted by the weighting, wherein the signal intensity of the target RFID tag is greater than a designated value.

8. A computer-readable, non-transitory medium storing a program which, when executed by a computer, causes the computer to perform a reading process, the reading process comprising:
-
first obtaining signal intensities of a plurality of RFID tags that are read at plural read processes; second obtaining the quantity of the RFID tags read at each of the plural read processes; weighting the signal intensities of the plurality of RFID tags in a manner that the greater the quantity of the RFID tags, the greater the signal intensity is weighted and that the smaller the quantity of the RFID tags, the less the signal intensity is weighted; and selecting a target FID tag from the plurality of RFID tags, the target RFID tag having a signal intensity weighted by the weighting, wherein the signal intensity of the target RFID tag is greater than a designated value.
