Abstract

<P>PROBLEM TO BE SOLVED: To solve the problem that almost all the systems for reading an RFID tag used in order to utilize an RFID system for performing data communication between antennas utilizing an electromagnetic coupling system utilized at fields of transportation and stock control can perform reading and writing only right above the RFID or in its vicinity though stating it as non-contact and thus, a worker confirms the RFID tag by transferring a container for transportation to a certain place by attaching the RFID to it or transferring an object. <P>SOLUTION: The RFID system uses the container for transportation with which reading and writing of the RFID tag become possible not only in the vicinity of the RFID tag but in the whole region of an embedded loop antenna by preliminarily embedding or installing the loop antenna in the container for transportation utilizing a principle that reading and writing of RFID tag information are possible in the whole region of the loop antenna by installing the RFID tag at a position where communication of the loop antenna is possible. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

The present invention provides a technology for reading and writing an RFID tag attached to a transport container for the purpose of improving the workability of workers in the transportation and storage and warehouse industries in general by improving the conditions for reading and writing the RFID tag. is there.

RFID tags are currently introduced in many transportation, storage and warehouse management systems and the like, and are characterized in that they can be managed easily and accurately by attaching RFID tags to transportation cargoes and containers for transportation.

However, most of the methods for reading and writing the RFID tag used to utilize the RFID system that performs data communication between antennas using the electromagnetic coupling method are RFID tags, although most of them are considered non-contact. Can be read and written directly above or near the object, so that the operator needs to move to the place where the RFID tag is attached or move the object to confirm the RFID tag .

Although it is possible to extend the reading / writing distance of the RFID tag even in the conventional product, it can be said that the usefulness is not necessarily fully utilized for the effect of reading / writing even in the blind spot. Absent.

The present invention has been made in view of the above circumstances, and the information on the RFID that could be read and written only above or in the vicinity of the RFID tag attached to the transport container is transport container. To provide an RFID system capable of easily and surely reading an RFID tag by a worker in the entire transportation and storage and warehousing industries by enabling reading and writing in a wide range of locations. With the goal.

In the present invention, communication of an RFID tag used for utilizing an RFID system that performs data communication between antennas using an electromagnetic coupling method is performed not only in the vicinity of the RFID tag but also in the entire area where a loop antenna is installed, that is, for transportation. The most important feature is that the RFID tag information can be read and written in a wide area of the container.

According to the first invention, the RFID tag used for utilizing the RFID system that performs data communication between the antennas using the loop antenna and the electromagnetic coupling method is disposed on the surface of the transport container or inside. The RFID tag can be read and written on the entire circumference of the loop antenna, and the loop antenna is installed not only in the vicinity of the RFID tag but also in the vicinity of the RFID tag by attaching or attaching the loop antenna in advance to the transport container. The RFID tag can be read and written in the entire area, that is, in a wide area of the transport container.

The second invention is a development of the first invention, and a RFID tag is attached to the RFID tag so that the RFID tag can be installed at a position where it can communicate with the embedded loop antenna. By exchanging, it becomes possible to reuse the transport container or traceability based on the transport object.

By attaching an RFID tag to a transportation container in which a loop antenna is embedded, it is possible to reduce the burden on workers who can be placed in a management system for transportation and parts without impairing other functions.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

An embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a schematic diagram of an RFID system using the present invention, 1 is an RFID tag, 2 is an RFID reader / writer, 3 is a transport container embedded with a loop antenna, and 4 is It is a buried loop antenna. Reference numeral 5 denotes a host computer for managing information. FIG. 2 is a schematic diagram of an RFID system using the second invention, and 6 is a pocket for replacing an RFID tag or a mounting jig.

As shown in FIG. 1, an RFID tag and a loop antenna arranged in a manner to be installed on the tag are embedded in the cardboard in advance, so that even if the position of the tag on the cardboard is away from the operator, the loop antenna It is possible to read and write in the entire area where the is installed, and work efficiency can be improved.

As shown in FIG. 2, by attaching a replacement unit or pocket for the RFID tag directly above the loop antenna, the RFID tag paired with the product to be transported by cardboard can be replaced without depending on the cardboard. It becomes possible to manage the traceability of the RFID tag paired with.

As described above, the RFID tag used for utilizing the RFID system that performs data communication between the antennas using the electromagnetic coupling method is installed at a position where the RFID tag can communicate with the loop antenna. The problem of realizing reading and writing of the RFID tag easily and surely without depending on it can be solved.

As an application example of the present invention, by attaching it to a transport container used in an article management system such as transport and storage or warehouse industry, the RFID tag can be easily and reliably read and written in transport and management of parts and products. It can be used as a means to

It is a system equipment structure schematic diagram of the RFID system of 1st invention. It is a RFID system schematic diagram using 2nd invention.
