[0071] FIG. 1(A) and FIG. 1(B) are diagrams showing the positional relationship between the wireless tag communication device and the wireless tag according to the embodiment. FIG. 1(A) is an example diagram in which the positions of the wireless tags TG1, TG2, and TG3 (hereinafter, simply referred to as TG1, TG2, and TG3) are fixed and the wireless tag communication device 100 moves. As a specific example of the configuration of FIG. 1(A), there is an actual situation where the wireless tag communication device 100 is installed in a moving body such as an automobile or a train car, and TG1 to TG3 are installed along a road or a road. installation (structure), etc.

[0072] FIG. 1(B) is an example diagram where the position of the wireless tag communication device 100 is fixed and TG1 , TG2 , and TG3 move. As a specific example in FIG. 1(B), there is an actual installation in which TG1 to TG3 are attached to items such as commodities and equipment, and transported to the wire...

[0139] In the second embodiment, a wireless tag communication device is installed on a mobile body such as an automobile or a train car, and a wireless tag is installed on a road or a route on which the mobile body travels. In other words, it is a configuration in which a mobile body moves on a road or a wireless tag on a road to be read.

[0140] Figure 9 A block diagram of the wireless tag communication device of the second embodiment is shown. The wireless tag communication device 100A of the second embodiment further includes a speed information acquisition unit 115 and a moving object information acquisition unit 116 in a control unit 110A. These units are realized by the processor 801 performing calculations and executing programs stored in advance in the storage unit 802 .

[0141] The velocity information acquisition unit 115 acquires the relative velocity between the wireless tag communication device 100A and TG1 to TG3 , and acquires the number of repetitions corr...

Abstract

The invention discloses a wireless label communication device, by which data in a wireless label can be received even the data is not detected during reading of the wireless label. The wireless label includes a communication portion and a control portion, wherein the communication portion receives the data stored in the wireless label from the wireless label; and the control portion, when the data from the wireless label is not detected or is wrong, controls the communication portion to send requery signal again after a specific time that the wireless label is in a responsible time.

Description

[0001] This application claims that the Japanese application with the filing date of January 22, 2016 and the application number of JP2016-010768 is the priority, and the content of the above application is cited. technical field [0002] The embodiments described in this specification relate to a wireless tag communication device that reads data from a wireless tag. Background technique [0003] In recent years, wireless tags storing identification information have become widespread, and are not only attached to items such as commodities and devices, but also begin to be attached to buildings, roads, and the like. As a wireless tag, there is an RFID tag (RFID: Radio Frequency Identifier: Radio Frequency Identification) that stores ID information and the like and performs short-range wireless communication of several cm to several m. When an RFID tag is read by a wireless tag communication device (reader / writer), product information, location information, etc. can be obtaine...
