Abstract:
1. An RFID evaluation system, comprising: a tag position and posture varying apparatus which accepts a manual operation from an operator to vary a position of an RFID tag and automatically varies a posture of the RFID tag, wherein the tag position and posture varying apparatus includes a crane which is fixed such that a position, a direction angle, and an elevation angle of the crane can be manually changed, and the RFID tag, which is fixed to the crane such that a posture may be controlled automatically; an antenna which transmits a transmit radio signal for testing to the RFID tag and which receives a receive radio signal transmitted from the RFID tag; and a controller which, for each combination of the position and the posture of the RFID tag, controls the antenna to measure a response radio wave strength of the RFID tag, wherein the controller includes a processor which measures the position of the RFID tag; and an information providing apparatus which provides information for moving the RFID tag to a target position, wherein the processor reports to the tag position and posture varying apparatus that the RFID tag moved to the target position; and the processor controls the antenna to measure the response radio wave strength of the RFID tag, when it is reported from the tag position and posture varying apparatus that a relative posture of the RFID tag relative to the antenna became a predetermined posture, wherein the tag position and posture varying apparatus includes a posture controller which provides successive control such that a relative posture of the RFID tag relative to the antenna becomes the predetermined posture when it is reported from the controller that the RFID tag moved to the target position; and the processor, after the relative posture of the RFID tag relative to the antenna became the predetermined posture, reports to the controller that the relative posture of the RFID tag relative to the antenna became the predetermined posture.
