Middleware device, driving method of reader and method for determining misrecognition of tag
First Claim
1. A method for determining tag misrecognition by a middleware device that is operated in relation to a reader, the method comprising:
- pre-storing receiving sensitivity of tag information of a tag of an object recognized at different distances from the reader;
acquiring the receiving sensitivity of tag information of the tag recognized at a preset time interval while the object is passing within a range of the reader; and
determining misrecognition of the tag by comparing the acquired receiving sensitivity with the pre-stored receiving sensitivity of tag information,wherein the determining of misrecognition of the tag comprises determining normal recognition of the taq when a plurality of receiving sensitivities received according to the different distances and pre-stored and a plurality of receiving sensitivities received according to the time interval are identical to each other.

Abstract
A middleware device, a driving method of a reader and a tag misrecognition determining method are provided. The middleware device operated in relation to a reader includes a storage configured to pre-store receiving sensitivity of tag information of a tag of an object recognized at different distances from the reader as a reference value, a communication interface configured to, in response to the object approaching to the reader, acquire the receiving sensitivity of tag information of the tag recognized at a preset time interval, and a tag misrecognition processor configured to compare the acquired receiving sensitivity with the pre-stored reference value to determine misrecognition of the tag.

7. A method for determining tag misrecognition by a middleware device that is operated in relation to a reader, the method comprising:
-
pre-storing receiving sensitivity of taq information of a taq of an object recognized at different distances from the reader; acquiring the receiving sensitivity of taq information of the taq recognized at a preset time interval while the object is passing within a range of the reader; and determining misrecognition of the taq by comparing the acquired receiving sensitivity with the pre-stored receiving sensitivity of tag information, wherein the pre-storing comprises pre-storing a power amount of a modulation back scattering signal transmitted by the tag in response to a radio signal provided by the reader as the receiving sensitivity, and the modulation back scattering signal is transmitted in an opposite direction to a direction of the radio signal transmitted by the reader.

8. A method for driving a reader that is operated in relation to a middleware device, the method comprising:
-
measuring, by a reader, receiving sensitivity of tag information of a tag of an object recognized at different distances from the reader; transmitting the measured receiving sensitivity to the middleware device; measuring, by a reader, the receiving sensitivity of the tag information of the tag recognized at a preset time interval while the object is passing within a range of the reader; and transmitting the receiving sensitivity measured according to the preset time interval to the middleware device for comparison with measured receiving sensitivity according to the different distances in order to determine misrecognition of the tag, wherein a radio signal transmitted to the tag from the reader is a linear polarization signal for the measuring of the receiving sensitivity. - View Dependent Claims (9, 10)
