Confirm whether or not (Step S22). If already registered, the product ID and product name are deleted from the asset management database, the product name corresponding to the received product ID is extracted from the asset database, and the product ID and product name are stored in the terminal. It is registered in the asset management database in association with the position information received from the device 31 (step S23). Such processing can occur when the location of an article has changed since it was last registered in the asset management database.

When a warehouse product is delivered, the server transmits information identifying the delivered product and the location of the delivered product to the terminal device 31 via the base station 41. The operator of the transportation means can immediately recognize the outgoing product and the location of the outgoing product.
- the terminal device 31 communicates with the servo 51 via the wireless LAN base station 41.
- the terminal device 31 may be a terminal device (for example, a mobile phone) that communicates with the server 51 via a mobile phone network.
- the camera unit of the camera-equipped mobile phone can be used as the light receiving unit 303 of the terminal device 31.
- a tag reader unit 305 and a light intensity determination circuit 304 are added to a cellular phone, and the light receiving element force is also determined by the light path from the CCD or other light receiving element in the camera unit to the signal output circuit.
- the terminal device 31 can be realized by adding a signal output path to the circuit 304.
- the terminal device 31 is a mobile phone, it is possible to make a call. Therefore, when applied to product management, work efficiency can be improved by talking between the administrator on the server side and the operator of the transportation means.
- the server 51 side stores the article location management information.
- Recollection means eg asset management database
- the terminal device 31 may include storage means (see FIG. 7) for storing the location management information of the product. In that case, the terminal device 31 does not need to transmit the position information received from the transmitting unit 154 and the article ID read from the RFID tag to the server 51, that is, the processing of steps S22 to S24 illustrated in FIG.
- the process of associating the location information received from the transmission unit 154 with the identification information read from the identification tag and storing it in the storage means is performed by the control unit 301 of the terminal device 31 (specifically, a program executed by the control unit 301). Executed.
- the processing in steps S22 to S24 may be simplified.
- the terminal name 31 is not stored in the storage means until the article name, and the terminal device 31 stores only the positional information and the article ID in association with each other, and after the collection of the positional information and the article ID for each article is completed.
- the terminal device 31 may be connected to a management device that manages articles such as assets, and the storage contents stored in the storage means of the terminal device 31 may be uploaded to the management device.
- the present invention can be applied to asset management and product management in, for example, a warehouse, a factory, a business office, and the like.
- FIG. 1 is a schematic diagram showing a first embodiment of an article position management system.
- FIG. 2 is a schematic diagram showing the illumination range of the illumination unit in more detail.
- FIG. 3 is an explanatory diagram showing a configuration example of an illumination unit.
- FIG. 4 is an explanatory diagram showing a specific configuration example of a light emitting unit and a transmission unit.
- FIG. 5 is an explanatory diagram for explaining a control example of a signal synthesis unit.
- FIG. 6 is a block diagram illustrating a configuration example of a terminal device.
- FIG. 7 is an explanatory diagram showing a configuration example of an asset management database.
- FIG. 8 is a flowchart showing an operation example of the terminal device.
- FIG. 9 is a flowchart showing an operation example of the server.
- FIG. 10 is an explanatory diagram showing a configuration example of a transmission unit in the second embodiment.
- FIG. 11 is a block diagram showing a configuration example of an illumination unit in the second embodiment.
