Abstract
A management device includes a reception strength acquirer that, when at least one reading device receives transmission signals transmitted by a plurality of transmission devices attached to respective management targets, acquires reception strengths of the transmission signals; and a degradation determinator that, on the basis of a comparison result between a newly acquired reception strength and an index value based on a plurality of reception strengths acquired during a predetermined period, determines whether or not one transmission device of the plurality of transmission devices has degraded. The one transmission device has transmitted a transmission signal corresponding to the newly acquired reception strength.
Claims8
A management device comprising:
- a reception strength acquirer configured to acquire, when at least one reading device receives transmission signals transmitted by a plurality of transmission devices attached to respective management targets, reception strengths of the transmission signals;
- and
- a degradation determinator configured to determine, on a basis of a comparison result between a newly acquired reception strength and an index value based on a plurality of reception strengths acquired during a predetermined period, whether or not one transmission device of the plurality of transmission devices has degraded, the one transmission device having transmitted a transmission signal corresponding to the newly acquired reception strength.
A transmission device management method comprising:
- acquiring, when at least one reading device receives transmission signals transmitted by a plurality of transmission devices attached to respective management targets, reception strengths of the transmission signals;
- and
- determining, on a basis of a comparison result between a newly acquired reception strength and an index value based on a plurality of reception strengths acquired during a predetermined period, whether or not one transmission device of the plurality of transmission devices has degraded, the one transmission device having transmitted a transmission signal corresponding to the newly acquired reception strength.
A non-transitory computer-readable medium having a program causing a computer of a management device to function as:
- a reception strength acquirer configured to acquire, when at least one reading device receives transmission signals transmitted by a plurality of transmission devices attached to respective management targets, reception strengths of the transmission signals;
- and
- a degradation determinator configured to determine, on a basis of a comparison result between a newly acquired reception strength and an index value based on a plurality of reception strengths acquired during a predetermined period, whether or not one transmission device of the plurality of transmission devices has degraded, the one transmission device having transmitted a transmission signal corresponding to the newly acquired reception strength.
