WIRELESS TAG COMMUNICATION DEVICE AND WIRELESS TAG COMMUNICATION PROGRAM |
| 摘要 |
According to one embodiment, a wireless tag communication device which communicates with a wireless tag includes a communication unit that designates a target wireless tag to read tag information stored in the wireless tag; a read-state determination unit that determines a read state of the tag information read by the communication unit; an output adjustment unit that varies a radio wave output to be transmitted to the wireless tag in response to the result of the determination by the read-state determination unit; a signal strength detection unit that detects the signal strength of a reply signal received from the wireless tag via the communication unit; and a control unit that switches the operation mode of the communication unit between a long-distance mode to communicate with the wireless tag while the output adjustment unit varies the radio wave output and a near-field mode to communicate with the wireless tag while the signal strength detection unit detects the signal strength. |

1. A wireless tag communication device which communicates with a wireless tag, comprising:
a communication unit that designates a target wireless tag to read tag information stored in the wireless tag; a read-state determination unit that determines a read state of the tag information read by the communication unit; an output adjustment unit that varies a radio wave output to be transmitted to the wireless tag in response to the result of the determination by the read-state determination unit; a signal strength detection unit that detects the received signal strength indicator of a reply signal received from the wireless tag via the communication unit; and a control unit that switches the operation mode of the communication unit between a long-distance mode to communicate with the wireless tag while the output adjustment unit varies the radio wave output and a near-field mode to communicate with the wireless tag while the signal strength detection unit that detects the signal strength. |
