Description

  The present invention relates to a system for specifying the position of an article that is used over a long period of time, such as durable consumer goods.

  In general, the method for electronically obtaining the position information of an article is a method using a transmission / reception module of a mobile phone (for example, a method of searching from a mobile phone network using a location registration function of a mobile phone, using an artificial satellite) Position information search (method of searching in conjunction with GPS: Global Positioning System) and a method of directly attaching a wireless IC tag (IC chip that communicates using radio waves) to an article and reading it with a wireless IC tag reader There is.

Further, Non-Patent Document 1 discloses a method of providing position information of an article with low power consumption and obtaining the position information of the article over a long period of time via a wide area ubiquitous network.

The “computer-readable recording medium” refers to a storage device such as a flexible medium, a magneto-optical disk, a portable medium such as a ROM and a CD-ROM, and a hard disk incorporated in a computer system. Further, the “computer-readable recording medium” dynamically holds a program for a short time, like a communication line when transmitting a program via a network such as the Internet or a communication line such as a telephone line. It is also possible to include those that hold a program for a certain time, such as a volatile memory inside a computer system serving as a server or client in that case. The program may be a program for realizing a part of the functions described above, and may be a program capable of realizing the functions described above in combination with a program already recorded in a computer system.

  As described above, according to the best mode for carrying out the present invention, it is possible to identify the position of the object by specifying the base station device 201 connected to the network, including the case where the object to be searched moves. Can be found within the communication range of the base station apparatus. Further, by obtaining a report from the user device 701, it is possible to limit to a specific place.

  In addition, by implementing the present invention, it is possible to know the range in which the object to be searched exists, so that the article to be searched is an article that is used for a long period of time such as durable consumer goods that require maintenance. In this case, the position information requester who performs maintenance can find the target object at an early stage. In addition, when an article to be searched for is a recall target, the recalled product can be efficiently collected.

  As described above, the embodiment of the present invention has been described with reference to FIGS. 1 to 8. However, the specific configuration is not limited to this embodiment, and various modifications can be made without departing from the spirit of the present invention. Changes are also included.

It is the block diagram which showed the 1st Example of the article search system by embodiment of this invention. It is the flowchart which showed the procedure which designates the target object in the article search system by embodiment of this invention. It is the flowchart which showed the procedure which performs an output request | requirement with respect to the designated target object in the goods search system by embodiment of this invention. It is the flowchart which showed the procedure which the target object outputs in the article search system by embodiment of this invention. It is the block diagram which showed the 2nd Example of the article search system by embodiment of this invention. It is the flowchart which showed the procedure which shows the information of the moved target object in the article search system by embodiment of this invention to a position information requester. It is the block diagram which showed the 3rd Example of the article search system by embodiment of this invention. It is the flowchart which showed the procedure in which a user apparatus notifies the positional information on the target object in the goods search system by embodiment of this invention.
