no. 1 Embodiment approach

[0041] Next, a first embodiment of a wireless tag reading device, a wireless tag state estimating device, a wireless tag state estimating system, and a wireless tag state estimating program according to the present invention will be described in detail with reference to the drawings.

[0042] (A-1) Configuration of the first embodiment

[0043] FIG. 1 is a block diagram showing a functional configuration of a wireless tag state estimation system according to the present embodiment. The wireless tag state estimation system 10 has the same Figure 13 The described conventional walking assistance system 1300 for the visually impaired has substantially the same configuration as that after adding the wireless tag state estimation device 30 .

[0044]The wireless tag 101 is a tag capable of transmitting and receiving information with another communication device through wireless communication, and corresponds to, for example, an IC tag based on RFID (Radio Frequency Identification)....

no. 2 Embodiment approach

[0099] Next, a second embodiment of a wireless tag reading device, a wireless tag state estimating device, a wireless tag state estimating system, and a wireless tag state estimating program according to the present invention will be described in detail with reference to the drawings.

[0100] (B-1) Configuration of the second embodiment

[0101] In the tag state estimation unit 34 of the wireless tag state estimation system 10 according to the first embodiment, a wireless tag that has not been read is detected by referring to the information in the tag usage information storage unit 33a, and a wireless tag whose operation has not been confirmed Tags are regarded as wireless tags that may have failed, and they are checked for confirmation.

[0102] On the other hand, the wireless tag state estimation system of the second embodiment differs from the first embodiment in that the tag state estimating unit 34 determines the certainty of failure (hereinafter expressed as "failure e...

Embodiment approach

[0125] Next, a third embodiment of a wireless tag reading device, a wireless tag state estimating device, a wireless tag state estimating system, and a wireless tag state estimating program according to the present invention will be described in detail with reference to the drawings.

[0126] (C-1) Structure of the third embodiment

[0127] As an example, the tag state estimating unit 34 of the wireless tag state estimating system according to the second embodiment extracts wireless tags in the vicinity of wireless tags whose operation has not been confirmed. In the wireless tag method, for example, when installing the wireless tag, the installation location information may be registered in advance. In this case, in order to facilitate the management of the installation locations of the installed wireless tags, the maintenance target tag information storage unit 32 may represent the installation locations using a hierarchical numbering system.

[0128] In the third embodiment...

Abstract

The invention provides a wireless label state reasoning system which includes a wireless label reading device and a wireless label state reasoning device. The wireless label reading device is hold by a mover for reading information from adjacent wireless label configured along a movable path by random mover, and is provided with a unit that can communicate with adjacent wireless label and obtain wireless label information, and a unit that provided obtained wireless label information to outer wireless label state reasoning device unit directly or processed. The wireless label state reasoning device is provided with a unit that registers with information configured wireless label; the wireless label state reasoning unit that can reason wireless label no-ensuring action according with configured information of the wireless label information and recorded and stored wireless label information.

Description

technical field [0001] The present invention relates to a wireless tag reading device, a wireless tag state estimating device, a wireless tag state estimating system and a wireless tag state estimating program, and can be applied, for example, to a system requiring a function of detecting a wireless tag failure. Background technique [0002] In roads and public facilities, services such as providing location information corresponding to the location to incoming users by placing wireless tags are gradually introduced. [0003] Figure 13 It is a block diagram showing the overall configuration of a walking assistance system for visually impaired persons described in Patent Document 1. FIG. The wireless tag 1301 is a wireless tag embedded in a guide area arranged to assist walking of the visually impaired. The wireless tag communication device 1302 is a terminal device used by pedestrians, and includes an electronic wand capable of communicating with the wireless tag 1301 to a...
