US 7,583,193 B2 · Method for supporting an antenna wiring, and a system

Abstract

It is desirable to make the antenna wiring more efficient in the building of an RFID system. The system includes antennas and readers connected in an arbitrary manner, in which calibration tags are installed on all the antennas. By reading the calibration tags, the system automatically generates the correspondences between the access paths and antenna logical names of the antennas, to serve as antenna configuration information. While the user generates combinations of the antenna logical names of the one or more antennas to be simultaneously driven, to serve as derive sequence information. The system compares the automatically generated antenna configuration information with the user-generated driving sequence information, and if there is an inconsistency in the setting of the both, generates an antenna rewiring procedure so as to resolve the inconsistency. The antenna rewiring procedure is generated as a combination of the substitution operation of the antenna wiring.
