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

(Embodiment)
First, an RFID system according to an embodiment of the present invention will be described with reference to FIGS. Here, the managed article 1 is shipped from the factory 40 (including the manufacturing company), and sold through stores (including personal stores and mass retailers) in each region (for example, region A and region B in FIG. 2). The location management of the managed article 1 when delivered to each customer's house will be described as an example.

  FIG. 1 is a schematic configuration diagram of an RFID system 5 according to an embodiment of the present invention, and FIG. 2 is an electrical block diagram of the RFID system 5.

  As shown in FIG. 1, paying attention to the fact that a logo 2b is always provided on the front side of the managed article 1 and designed in a unique typeface by combining characters such as company name, product name, title name, A logo plate 2 with an RFID tag provided with an RFID tag 3 for managing the managed article 1 is attached to the back side of the front decorative plate 2a on which the logo 2b is formed.

  That is, as shown in FIGS. 1 and 2, in the RFID system 5, the logo plate 2 with an RFID tag is provided on the outer surface 1 a on the front side of each managed article 1. And after registering the merchandise information of all the managed articles 1 shipped from the factory 40 in the database 41a (hereinafter referred to as “DB”) of the management apparatus 41 which is an information processing apparatus, The managed article 1 is then shipped. In each regional store 43, product information data is acquired by the information processing device 44 (for example, a personal computer) of the store 43 via the network 42, and the managed article 1 is collated based on the product information data. Then, location information in which product information of the managed article 1 and location information where the managed article 1 is located is created and managed by the DB 44a.

  In the store 43, the location information of the managed article 1 in which customer information (location information such as an address, contact information such as a telephone number) is associated with customer product information (product information delivered to each customer) is processed as an information processing device. The location information is managed by the DB 44 a created by the information processing apparatus 44 and provided in the information processing apparatus 44. The dealer 43 can easily know the location of the managed article 1 by searching the location information of the managed article 1 stored in the DB 44 a of the information processing apparatus 44.

  In the store 43, when the store clerk receives the goods or displays the managed article 1, the reader / writer 4 is brought close to the logo plate 2 with the RFID tag of the managed article 1, and the RFID provided on the logo board 2 with the RFID tag by the reader / writer 4. Read tag 3. Also, when the managed article 1 is delivered to the customer's house where the managed article 1 is the purchaser, the reader / writer 4 is brought close to the RFID tag-attached logo plate 2 of the managed article 1 delivered by the store clerk, and the logo with the RFID tag is attached. The RFID tag 3 provided on the plate 2 is read by the reader / writer 4. Then, after returning to the store 43, the store clerk connects the reader / writer 4 to the information processing device 44, causes the information processing device 44 to read the product information of the managed article 1 read by the reader / writer 4 at the customer's house, and stores it in the DB 44a. Update the stored location information. The reader / writer 4 and the information processing apparatus 44 are connected by wire or wirelessly. The reader / writer 4 includes a memory 4a, and stores the product information of the managed article 1 read by the reader / writer 4 in the memory 4a. As a result, the reader / writer 4 can be used alone and can be easily carried.

  In this way, the store 43 can efficiently manage the location information indicating what managed articles 1 exist in which house in which region.

  When a customer requests disposal of the managed article 1, the store clerk of the store 43 searches the customer location by using the DB 44 a of the information processing apparatus 44, visits the house at the searched location, and collects the managed article 1. To do. At this time, the store clerk reads the RFID tag 3 provided on the RFID tag-attached logo plate 2 of the managed article 1 by the reader / writer 4. Then, after returning to the store 43, the store clerk connects the reader / writer 4 to the information processing device 44, and stores the product information stored in the memory 4 a of the reader / writer 4 (product information of the collected managed article 1) via the control unit 8. The location information stored in the DB 44a of the information processing device 44 is updated. That is, in the information processing apparatus 44, information indicating that the DB 44a has been collected or repaired is added to the location information, and history information relating to location management of the managed article 1 is also stored. As a result, it is possible to confirm the managed article 1 that does not need to be repaired and collected, and take appropriate measures.

  In addition, even when it is performed by a recycling company designated by the manufacturing company that collects the managed article 1 or another collection company, each company reads the RFID tag 3 provided on the logo plate 2 with the RFID tag by the reader / writer 4, The history management is performed by adding the collected information to the location information of the managed article 1. Further, if the location information managed by the store 43 and the location information (including repair information) of the managed article 1 collected by the recycler or another collecting company are linked, more detailed information on the managed article 1 can be obtained. Location management can be performed.

  As described above, in the present embodiment, when performing the location management of the managed article 1, the store clerk or the related contractor moves a heavy refrigerator or the like to search for a nameplate attached to the back surface or the lower surface. The trouble of confirming the merchandise information of the managed article 1 can be saved, and the RFID tag-attached logo plate 2 on the front side of the managed article 1 can be easily found. Then, the RFID tag 3 provided on the logo plate 2 with the RFID tag can be easily read by bringing the reader / writer 4 close thereto. Thereby, it is easy to find the location of the RFID tag 3 read by the reader / writer 4, and the location management of the managed article 1 can be performed efficiently.

  Even if a situation that requires repair of the managed article 1 occurs in a manufacturing company or the like, and it is necessary to collect the managed article 1 (for example, a specific production number) and replace parts, the factory 40 If each dealer 43 manages the location information of the managed article 1 by contacting each dealer 43 in each region, which is the shipping destination from the company, it is possible to respond quickly by using this location information. . That is, the store clerk of each store 43 uses the location information managed in the DB 44a of the information processing device 44 to know which house in which area the managed article 1 is delivered, and selects each house to be targeted. The managed article 1 to be repaired can be collected, replaced, and repaired quickly. Thereby, the purchaser can use the managed article 1 safely and safely.

  Specifically, a tag circuit unit 6 is mounted on the RFID tag 3 of the logo plate 2 with an RFID tag attached to each managed article 1 as shown in FIG. The memory 6a for storing the identification information is incorporated.

  The RFID tag 3 affixed to each managed article 1 has individual identification information for each managed article 1 affixed thereto stored in the memory 6 a of the tag circuit unit 6. The identification information is, for example, product information such as a product name for identifying an individual managed article 1, a model number that is model information, a manufacturing number, a manufacturing date, and a manufacturing location. These pieces of information are used alone or in combination to identify the individual managed article 1. Thus, in the RFID system 5, the managed article 1 can be specified using the identification information of the RFID tag 3, and for example, a refrigerator whose “Production number of model number A is ABC123” can be specified.

  The reader / writer 4 shown in FIG. 2 performs the specific work. The reader / writer 4 communicates with the RFID tag 3, reads the identification information stored in the memory 6a provided inside the RFID tag 3, It is specified whether or not the management article 1 is.

  When the reader / writer 4 is brought close to the logo plate 2 with an RFID tag of the managed article 1 and the RFID tag 3 provided on the logo plate 2 with the RFID tag is read by the reader / writer 4, as shown in FIG. An inquiry is made from the control unit 8 to the RFID tag 3, for example, “Are the manufacturing number of model number A ABC number 123?”.

  This inquiry signal modulates a 953 MHz carrier wave by the modulation circuit 9 and is output to the RFID tag 3 via the transmission circuit 10 and the antenna 11.

  The RFID tag 3 receives an inquiry signal by the antenna 12 of the tag antenna unit 7 and generates a DC voltage from the carrier wave of the signal from the antenna 12 by the diode 13 and the capacitor 14, and the control circuit uses the generated DC voltage. 15, the demodulation circuit 16, the modulation circuit 17, and the memory 6a are activated.

  Then, in response to an instruction from the control circuit 15, the demodulator circuit 16 demodulates the inquiry “Are the model number A manufacturing number ABC123?” From the received signal.

  Further, the control circuit 15 reads the individual identification information stored in the memory 6a simultaneously with the instruction to the demodulation circuit 16.

  When the identification information stored in the memory 6a is “Production number of model number A is ABC123”, the control circuit 15 indicates that “Production number of model A is ABC123” in response to the inquiry. Is answered by turning the switch 18 on and off via the modulation circuit 17.

  That is, when the switch 18 is turned on, the point a of the antenna 12 and the point b of the ground portion 19 are short-circuited, and conversely, when the switch 18 is turned off, the point a of the antenna 12 and the point b of the ground portion 19. As a result of such a repeated pattern of ON / OFF of the switch 18, the conclusion is that “the manufacturing number of the model number A is ABC123” from the antenna 12 of the RFID tag 3 to the antenna 20 of the reader / writer 4. Is reported.

  In the reader / writer 4, a reply signal is transmitted to the demodulating circuit 22 through the receiving circuit 21, and the control unit 8 confirms the existence of “the manufacturing number of the model number A is ABC123” by the demodulated signal. It can be confirmed by displaying it on a section (not shown).

  In addition, even though the control unit 8 of the reader / writer 4 makes an inquiry to the RFID tag 3 that “the manufacturing number of the model number A is ABC123”, the RFID that stores “the manufacturing number of the model number A is ABC123” If the tag 3 does not exist, there is no reply, so the reader / writer 4 confirms that “the manufacturing number of the model number A is ABC123” does not exist from this “no reply”.

  In FIG. 2, a power supply circuit 23 that supplies power, a clock circuit 24 that generates a clock to each unit, and a capacitor 25 for impedance matching of the tag antenna unit 7 are provided.

  By the way, as shown in FIG. 1, by providing the RFID tag 3 on the logo plate 2 with the RFID tag, the store clerk can easily find the place where the RFID tag 3 is located and perform the reading location management efficiently by the reader / writer 4. However, the reading performance of the RFID tag 3 may be deteriorated. That is, since the RFID tag 3 communicates with the reader / writer 4 through the tag antenna unit 7, the logo 2b of the logo plate 2 with the RFID tag and the surface decorative plate 2a are formed of metal such as stainless steel or metal plating. In addition, the antenna characteristics of the tag antenna unit 7 deteriorate due to the influence of the metal. This is presumably because the tag antenna unit 7 is affected by impedance mismatching, radio wave shielding, radio wave irregular reflection, frequency shift, and the like.

  Therefore, the present embodiment has a configuration as shown in FIG. FIG. 3 is an exploded perspective view of the logo plate 2 with RFID tag in the embodiment of the present invention.

  That is, the RFID tag-attached logo plate 2 is provided with an RFID tag 3 for managing the management article 1 on the back side of the front decorative plate 2a on which the metal logo 2b is formed. The RFID tag 3 is provided on the substrate 3a. A tag circuit unit 6 for storing and holding identification information and a tag antenna unit 7 electrically connected to the tag circuit unit 6, and the mounting surface on which the tag antenna unit 7 of the substrate 3a is mounted is more than the surface decorative board 2a. It is affixed to the surface decorative board 2a through the thick resin layer 26. FIG. Further, the back surface opposite to the mounting surface of the substrate 3a is attached to the outer surface 1a of the management article 1 made of a resin such as plastic with a double-sided adhesive tape or the like through a resin layer 27 thicker than the substrate 3a. Yes. As the resin layers 26 and 27, a low-loss material that does not shield the electric field from the tag antenna unit 7, for example, a plastic sheet such as a polyethylene terephthalate (PET) material is used. Examples of the management article 1 whose outer surface 1a is made of resin include a telephone, a FAX, and an air conditioner.

  Thus, since the board | substrate 3a is affixed on the surface decorative board 2a through the resin layer 26 thicker than the surface decorative board 2a, it is constant between the logo 2b or the surface decorative board 2a, and the tag antenna part 7. A distance gap can be provided, and even if the logo 2b or the surface decorative plate 2a is made of metal, it is possible to suppress deterioration of the antenna characteristics of the tag antenna unit 7 due to the influence of the metal.

  In addition, the thickness of the resin layer 26 can be reduced in order to prevent the RFID tag-attached logo plate 2 from protruding too much from the outer surface 1a of the managed article 1 and coming into contact with the surrounding article during handling. The surface decorative board 2a was formed. That is, the surface decorative board 2a was formed of resin, and the logo 2b was formed on the surface of the surface decorative board 2a by metal plating. This prevents the surface decorative plate 2a from affecting the electric field generated from the tag antenna portion 7 and prevents radio waves from passing through the gap between the logos 2b. Therefore, even if the thickness of the resin layer 26 is reduced, the tag Deterioration of antenna characteristics of the antenna unit 7 can be suppressed.

  In addition, although the case where the outer surface 1a of the managed article 1 was made of resin was described, in the case of the metal outer surface 1a, the antenna characteristics of the tag antenna unit 7 deteriorate due to the influence of the metal. This is presumably because the tag antenna unit 7 is affected by current outflow, frequency shift, impedance mismatch, and the like due to approach or contact with metal (low impedance).

  Examples of the electrical appliance in which the outer surface 1a is made of metal include a refrigerator, a microwave oven, a washing machine, and a television receiver.

  Therefore, in this embodiment, when the outer surface 1a of the managed article 1 is made of metal as described above, the configuration shown in FIG. 4 is adopted. FIG. 4 is an exploded perspective view showing another example of the logo plate 2 with an RFID tag in the embodiment of the present invention when the outer surface 1a of the managed article 1 is made of metal.

  That is, as shown in FIG. 4, the RFID tag-attached logo plate 30 is provided with an RFID tag 3 for managing the management article 1 on the back side of the front decorative plate 2a on which the metal logo 2b is formed, The RFID tag 3 includes a tag circuit unit 6 that stores and holds identification information on a substrate 3a, and a tag antenna unit 7 that is electrically connected to the tag circuit unit 6, and a mounting surface on which the tag antenna unit 7 of the substrate 3a is mounted. Is attached to the surface decorative plate 2a through a resin layer 26 thicker than the surface decorative plate 2a. The RFID tag-attached logo plate 30 is further adhered to the magnetic material sheet 28 via a resin layer 27 having a thickness larger than that of the substrate 3a on the back side opposite to the mounting surface of the RFID tag 3 on the substrate 3a. The sheet 28 is bonded to the outer surface 1a of the managed article 1 with a double-sided adhesive tape or the like through a resin layer 29 thicker than the substrate 3a. The magnetic sheet 28 is made of a high permeability material such as ferrite or sendust, and has a higher impedance than metal. The magnetic sheet 28 is laminated so as to cover the tag antenna portion 7 of the substrate 3a.

  Thereby, when the outer surface 1a of the managed article 1 is made of metal, the vicinity in the vicinity of the metal surface is a very low impedance region as described above, and the electric field of the tag antenna unit 7 approaches the metal. The closer it is, the closer it is to zero and the antenna characteristics deteriorate rapidly. On the other hand, since the magnetic sheet 28 has a higher impedance than that of the metal, the electric field does not become zero even when the tag antenna unit 7 approaches the magnetic sheet, and becomes a high value, thereby preventing deterioration of the antenna characteristics. The reader / writer 4 and the RFID tag 3 can communicate with each other. Further, a gap of a certain distance is provided between the tag antenna portion 7 and the magnetic sheet 28 by the resin layer 27 so as not to be affected by frequency shift or loss due to the magnetic sheet 28. At the same time, by providing a gap of a certain distance between the metal surface and the tag antenna unit 7, the deterioration of the antenna characteristics of the tag antenna unit 7 due to the influence of the metal on the outer surface 1 a in the managed article 1 is further suppressed. As a result, communication between the reader / writer 4 and the RFID tag 3 shown in FIG. 2 is appropriately performed.

  As described above, according to the present embodiment, the RFID tag-attached logo plates 2 and 30 are RFIDs for managing the management article 1 on the back side of the front decorative plate 2a on which the metal logo 2b is formed. A tag 3 is provided, and the RFID tag 3 includes a tag circuit unit 6 that stores and holds identification information on a substrate 3a, and a tag antenna unit 7 that is electrically connected to the tag circuit unit 6, and the tag antenna unit 7 of the substrate 3a. Is mounted on the surface decorative plate 2a through a resin layer 27 thicker than the surface decorative plate 2a. Further, the back surface opposite to the mounting surface of the substrate 3a is attached to the resin outer surface 1a of the management article 1 with a double-sided adhesive tape or the like via the resin layer 27.

  Thereby, since the RFID tag 3 is affixed to the surface decorative board 2a via the resin layer 26 having a predetermined thickness, the antenna characteristics of the tag antenna unit 7 are affected by the metal of the logo 2b and the surface decorative board 2a. Deterioration can be suppressed.

  In addition, the RFID system 5 includes the above-described logo plates 2 and 30 with RFID tags, and a reader / writer 4 that reads identification information relating to the managed articles of the RFID tags 3 provided on the logo plates 2 and 30 with RFID tags, An information processing device 44 that manages location information in which identification information related to the managed article 1 and location information are associated with each other, and the RFID tag-attached logo plates 2 and 30 are attached to the outer surface 1a on the front side of the managed article 1; Since the RFID tag 3 of the logo plates 2 and 30 with tags is read by the reader / writer 4 and the location management of the article 1 is managed, even if the logo 2b or the decorative face plate 2a is made of metal, The deterioration of the antenna characteristics of the tag antenna unit 7 is suppressed, and the reader / writer 4 and the RFID tag 3 are appropriately communicated. Further, since the logo plates 2 and 30 with RFID tags are provided on the outer surface 1a on the front side of the managed article 1, those who work in the factory 40, the store 43, the customer's house, etc. 2 and 30 are easily found, the reader / writer 4 is brought close to the logo plates 2 and 30 with RFID tags, and the RFID tag 3 provided on the logo plates 2 and 30 with RFID tags is read by the reader / writer 4 to identify the management article 1. Information (such as product information) can be acquired. Thereby, since the location of the RFID tag 3 can be easily found, the location management of the managed article 1 can be performed efficiently.

  Note that history information may be added to the identification information of the RFID tag 3. For example, when a part of each managed article 1 is replaced, the part number, replacement date, etc. of the replaced part are stored as history information in the memory 6a. As a result, information such as “the compressor of the model number A with the production number ABC123 has been replaced in year / month” can be known, and the managed article 1 being confirmed can be excluded from the repair target.

  As described above, the RFID tag-attached logo plate of the present invention is provided with an RFID tag for managing managed articles on the back side of the front decorative plate on which a metal logo is formed, and the RFID tag is a substrate. A tag circuit unit for storing identification information and a tag antenna unit electrically connected to the tag circuit unit, and a mounting surface on which the tag antenna unit of the substrate is mounted is thicker than the surface decorative board Because it is affixed to the surface decorative board via the surface, a certain distance can be provided between the logo and the tag antenna part, and the deterioration of the antenna characteristics of the tag antenna part due to the influence of the metal logo is suppressed. be able to. Thereby, even if the logo is made of metal, it is expected to be widely used in a logo plate with an RFID tag that can suppress deterioration of antenna characteristics and an RFID system using the logo plate.
