Problems solved by technology

[0006] However, in the method of searching for an article by carrying an RFID reading communication device for reading an RFID tag affixed to the article, it is not easy to find the article efficiently when the range of the searched place is wide.
In addition, when realizing the miniaturization of the RFID reading communication device, there is a fear that the possible range of communication between the RFID tag attached to the article and the RFID reading communication device will be reduced, and it will not be easy to search for the article.

Embodiment approach 1

[0025] In this embodiment, an example of an article management system will be described with reference to the drawings.

[0026] The article management system shown in this embodiment includes a semiconductor device capable of wirelessly transmitting and receiving data (also referred to as RFID (radio frequency identification) tag, IC tag, RF tag, wireless tag, electronic tag, hereinafter referred to as "RFID tag") ”), a wireless communication device, and a portable instrument, and by using the portable instrument to communicate with the wireless communication device, the whereabouts of the items equipped with RFID tags can be grasped. Hereinafter, an example of the article management system will be specifically described with reference to FIG. 1 .

[0027] The article management system shown in FIG. 1 is composed of an RFID tag 102 attached to an article 101, a wireless communication device 103, a portable device 104, and the like.

[0028] The wireless communication device ...

Embodiment approach 2

[0058] In this embodiment, the configuration of the article management system of the present invention will be described with reference to the drawings. Specifically, a case will be described in which, in addition to detecting the fall of an item to which an RFID tag is attached (in which area the item exists), the position of the item in the area is also detected.

[0059] Note that as the position detection method described in this embodiment, the following method is given as an example: when a signal propagates in space, the phenomenon that the electric field strength decreases according to its propagation distance is used to detect RFID tags and read them. / the distance between the writers, and the location of the RFID tag.

[0060] First, the position detection method shown in this embodiment will be described with reference to FIG. 4 . Note that a case where the position of the RFID tag 202 attached to the item 201 in the area 200 is detected is shown in FIG. 4 .

Abstract

An article management system which can efficiently search for the whereabouts of an article. The article management system for managing the whereabouts of an article existing in any of a plurality of sections includes radio communication devices provided in the respective sections, and an RFID tag and a portable device that are communicable with the radio communication device by radio. The RFID tag is attached to the article. The article is detected through communication between the RFID tag and one of the radio communication devices provided in the respective sections. Further, in which of the plurality of sections the article exists is specified through communication between the portable device and the radio communication devices provided in the respective sections.

Description

technical field [0001] The invention relates to an item management system, in particular to an item management system utilizing wireless communication for item management. Background technique [0002] Generally speaking, in the case of managing a plurality of items to be traded, management is performed by a method such as registering data of the item in a database and placing the item in a predetermined place. On the other hand, articles such as daily necessities are usually not individually managed, so there is a fear that when the location of the article is changed, its whereabouts will be lost and it will take time to find it. As a result, a person needs to remember where the item is at all times. [0003] However, it is not easy for people to remember the whereabouts of objects at any time. In particular, it becomes less and less easy to grasp the whereabouts of items as time elapses or the memory becomes blurred due to aging. In addition, even when the whereabouts o...
