Abstract:
In a configuration for detection of a movement state of a radio tag using a phase difference of a response wave from the radio tag, a phase φ[i] and a measurement time t[i] of a response wave from a radio tag measured are sequentially stored in a memory. A difference from a previous phase and a difference from a previous measurement time with respect to each phase φ[i] stored in the memory are calculated as a phase difference Δφ[i] and a time difference Δt[i]. A phase addition value φsum[i] obtained by cumulatively adding a plurality of the phase differences Δφ[i] is calculated so as to correct a phase difference in which the corresponding time difference Δt[i] among the calculated plurality of the phase differences Δφ[i] exceeds a time threshold tsa [i], whereby the movement state of the radio tag is detected based upon the calculated phase addition value φsum[i].

Claim (Index 1):
A radio tag movement detection device for detecting a movement state of a radio tag, comprising:\n a phase measurement part configured to measure a phase of a response wave from the radio tag; a memory configured to sequentially store a phase measured by the phase measurement part together with a measurement time at which the phase is measured; a first calculation part configured to calculate a difference from a previous phase and a difference from a previous measurement time with respect to each phase stored in the memory as a phase difference and a time difference; a second calculation part configured to calculate a phase addition value obtained by cumulatively adding a plurality of the phase differences so as to correct a phase difference in which the corresponding time difference among the plurality of the phase differences calculated by the first calculation part exceeds a predetermined threshold; and a detection part configured to detect the movement state of the radio tag based upon the phase addition value calculated by the second calculation part, wherein a required time when a phase measured by the phase measurement part is changed by n is obtained by a movement distance and a movement average speed of the radio tag, and the predetermined threshold is set to become equal to or less than half of the required time.
