Description

  The present invention receives a command signal transmitted from a radio frequency identification (hereinafter referred to as RFID) reader / writer and updates / writes tag information stored in a memory in accordance with the information of the command signal, or the tag The present invention relates to an RFID tag used in a radio frequency RFID system using a UHF band, a microwave band, or the like that transmits information as a read signal to an RFID reader / writer. In particular, an RFID tag is provided on the animal ear tag, and is fixed to the ears of animals such as cattle, pigs, sheep and other livestock and horses (hereinafter referred to as animals to be managed), The present invention relates to an animal ear tag RFID tag for performing individual management.

  The RFID system is a system that performs wireless communication between an RFID tag including an IC chip and an RFID reader / writer. There are two types of RFID tags: an active tag that is mounted with a battery and is driven by its power, and a passive tag that is driven by receiving power from the RFID reader / writer and using it as a power source. Since the active type has a battery compared to the passive type, there are advantages such as communication distance and communication stability, but there are also disadvantages such as complicated structure, larger size, and higher cost. In addition, with recent improvements in semiconductor technology, IC tags for passive tags have become smaller and higher performance, and the use of passive tags in a wide range of fields is expected. In the passive tag, in the electromagnetic induction method (HF band is typical) applied to the RFID tag having a long wave band and a short wave band, the transmission antenna coil of the RFID reader / writer and the antenna coil of the RFID tag are used. A voltage is induced in the RFID tag by the electromagnetic induction action, and the IC chip is activated by this voltage to enable communication. Therefore, the RFID tag operates only within the induction electromagnetic field by the RFID reader / writer, and the communication distance becomes about several tens of centimeters.

  In addition, in radio frequency RFID tags such as UHF band and microwave band, the radio wave system is applied, and power is supplied to the IC chip of the RFID tag by radio waves, so the communication distance is about 1 to 7 m. It has improved significantly. Therefore, simultaneous reading of a plurality of RFID tags, reading of a moving RFID tag, and the like, which have been difficult to realize with a long wave band and a short wave band RFID system with a short communication distance, are possible. Therefore, the range of use is greatly expanded, and application to an animal ear tag RFID tag is considered to be one of the useful utilization methods.

  2. Description of the Related Art Conventionally, an animal ear tag RFID tag has a male shaft portion that penetrates an animal's ear and a female shaft portion to which the male shaft portion is fitted, and a tag is attached to both the male shaft portion and the female shaft portion. A part of such a tag part in which an RFID tag (IC chip) is incorporated and a code for an optical reading means such as an ID or barcode is printed on the other surface is the ear of the animal to be managed. There is one that is attached to the earphone and manages an individual of the animal to which the ear tag is attached (for example, see Patent Document 1). Note that the ID or barcode printed on the other side of the bill part has an antenna with an IC chip connected to the bill part and can be managed individually by RFID. In order to enable individual identification even by reading, an identification number is printed on the bill portion.

In the drawing corresponding to the front view of the animal ear tag RFID tag in the present application, the reference numeral of the RFID tag 5 in a transparent state is omitted and is not displayed. Further, the first bill portion 3 or the second bill portion 4 (for example, FIG. 1C) in which the hollow portion 5a is formed, and the first bill portion 3 or the second bill portion (for example, the figure) that is not so. 1 (b)), there is not much difference in the front view of the animal ear tag RFID tag, and therefore the front view of the animal ear tag RFID tag is made common for the sake of simplicity (for example, FIG. 1 (a)). ). In the drawings, the same reference numerals denote the same or corresponding parts, and detailed descriptions thereof are omitted.

  1 to 7, reference numeral 8 denotes an animal to be managed that is managed by an RFID system using an animal ear tag RFID tag, and 9 denotes an ear of the animal 8 to be managed. In the present application, a cow is taken as an example. Reference numeral 10 denotes an animal ear tag RFID tag, a space in which the ear 9 is disposed, 11 a male shaft base formed on the male shaft portion 1, 12 a female shaft base formed on the female shaft portion 2, and 13 an own An RFID tag 5 (animal ear tag RFID tag) that is attached to an animal 8 to be managed in the transmission / reception area and can update / write / read tag information when it exists or is moving. A reader / writer 14 is an antenna that transmits an interrogation wave (transmission wave) from the RFID reader / writer and receives a return wave from the RFID tag 5. In the drawings, the same reference numerals denote the same or corresponding parts, and detailed descriptions thereof are omitted.

  The animal ear tag RFID tag according to Embodiment 1 is configured as shown in FIG. As shown in FIG. 1 (a), the surface of the first tag portion 3 to which the RFID tag 5 is attached faces the front, and an ID means an identification number printed on the label surface of the RFID tag 5 from the protective layer 7 And the barcode is visible. The identification number is a unique number set for each animal 8 to be managed. The method for attaching the RFID tag 5 to the first tag portion 3 may be an adhesive or the like, but it may be fixed to the first tag portion 3 together with the protective layer 7 by an adhesion method such as heat fusion.

  The shape of the installation surface of the RFID tag 5 in the first bill portion 3 may be a flat surface as shown in FIG. 1B, or may be a hollow portion 5 that is recessed as shown in FIG. . In this case, since the RFID tag 5 does not protrude from the first tag part 3, the possibility that the RFID tag 5 is destroyed can be reduced. Therefore, the RFID tag 5 is visible in FIG. 2A, but in FIG. 2B, the RFID tag 5 is invisible because the RFID tag 5 is in the recess 5a. Yes. When the RFID tag 5 is formed (installed) in the recess 5, the shape of the recess 5 is not necessarily recessed in the shape of the RFID tag 5 as long as the RFID tag 5 can be stored. May be.

  As shown in FIG. 1, the first bill portion 3 and the second bill portion 4 are thin at the top, and the male shaft portion 1 formed on the top of the first bill portion 3 is an animal 8 to be managed. The ear 9 can be penetrated. As shown in FIGS. 1 and 2, the female shaft portion 2 formed on the upper portion of the second bill portion 4 and fitted with the male shaft portion 1 can penetrate the ear 9 of the animal 8 to be managed. It has become a thing. In the present application, the female shaft portion 2 is described using a shape that covers most of the male shaft portion 1, but the female shaft portion 2 is attached to the tip of the male shaft portion 1. It is not necessary to have a shape that fits only the formed sharp portion or the periphery of the sharp portion, that is, a shape that covers most of the male shaft portion 1.

  As shown in FIG. 1, the RFID tag 5 is formed on the lower side of the first tag part 3, that is, on the side opposite to the male shaft part 1 formed on the upper part of the first tag part 3. Since the RFID tag 5 can be moved away from the fitting portion between the male shaft portion 1 and the female shaft portion 2 where the first tag portion 2 is in close contact with the ear 9 of the target animal 8, the ear of the animal 8 to be managed 9 (living body) can reduce the influence on the RFID tag 5. As shown in FIG. 3 (b), it is better that the ears 9 of the animals 8 to be managed are not located on the back surface of the RFID tag 5, but even if the ears 9 are present in a large part of the space 12, the males 9 By merely moving the RFID tag 5 away from the fitting portion between the shaft portion 1 and the female shaft portion 2, the influence of the ear 9 on the RFID tag 5 can be reduced.

  As shown in FIG. 3 (a), the ear 9 is arranged between the first bill portion 3 and the second bill portion 4, and the male shaft portion 1 is inserted into the female shaft portion 2 so as to fit each other. By doing so, the mounting of the animal ear tag RFID tag according to Embodiment 1 to the ear 9 is completed. FIG. 3B is a view showing the state after the mounting. The fitting between the female shaft portion 2 and the male shaft portion 1 can be easily performed by using an ear tag mounting device. Further, as shown in FIG. 4, a male shaft portion 1 is formed on the second bill portion 4, and a female shaft portion 2 is formed on the first bill portion 3 to form the second bill portion 4 and the first bill. The part 3 may be fitted.

  As shown in FIGS. 3 and 4, the male shaft portion 1 can penetrate the ear 9, and the female shaft portion 2 is fitted with the male shaft portion 1. Depending on the shape of the female shaft part 2, only the female shaft part 2 may penetrate the ear 9. Specifically, as described above, “the male shaft portion 1 is formed only by the sharpened portion formed at the tip of the male shaft portion 1” or “the main portion of the male shaft portion 1 is the tip of the shaft portion 3. It is conceivable that it is a “sharp part formed on the surface”. Even in such a case, for the sake of convenience, if the shaft formed by fitting the male shaft portion 1 and the female shaft portion 2 penetrates the ear 9, this state is also referred to as “male shaft portion 1 “It penetrates” or “male shaft portion 1 can penetrate ear 9”.

  In FIG. 1 to FIG. 4, the bill portion (the first bill portion 3 and the second bill portion 4) is formed on both the male shaft portion 1 and the female shaft portion 2 that are fitted. The bill portion not provided may be configured to have only the functions of the male shaft portion 1 or the female shaft portion 2. In that case, not the relationship between the first bill portion 3 and the second bill portion 4, but the first bill portion 3 and the male shaft portion 1 and the female shaft portion 2, or the second bill portion 4 and the female shaft. It becomes the relationship of the part 2 and the male shaft part 1. As shown in FIG. 5A, when the first tag portion 3 is not provided on the male shaft portion 1, the shaft base portion 11 having a shape that does not fall off from the ear 9 of the animal to be managed by the male shaft portion 1 alone. It is necessary to have. As shown in FIG. 5 (b), when the second tag portion 4 is not provided in the female shaft portion 2, the shaft base portion 12 having a shape that does not fall off from the ear 9 of the animal to be managed by the female shaft portion 2 alone. It is necessary to have. The shape of the shaft base 11 and the shaft base 12 includes a button type.

  6 and 7 will be used to describe the details of individual identification and management of the animal 8 to be managed by the animal ear tag RFID tag according to the first embodiment. FIG. 6 shows a state in which the animal ear tag RFID tag according to Embodiment 1 is attached to the ear 9 of the animal 8 to be managed. FIG. 7 shows a state in which the identification number is obtained from the animal 8 to be managed wearing the animal ear tag RFID tag according to Embodiment 1 using the RFID reader / writer 13.

  The RFID tag 5 stores the tag information (identification number) in the memory of the IC chip 6 in accordance with the use (individual identification, individual management, etc.) using the RFID system. The RFID reader / writer 13 Tag information can be updated, written, or read when the RFID tag 5 is present or moved (attached to the animal 8 to be managed) in its own transmission / reception area. The RFID reader / writer 13 transmits a command signal for instructing the RFID tag 5 to update / write or read the transmission signal from the antenna 14 of the RFID reader / writer 13 to the RFID tag 5. The antenna 6a of the RFID tag 5 receives the transmission wave, and the transmission wave is detected and stored (smoothed) by the power supply control circuit in the RFID tag 5 or the IC chip 6 to generate an operation power source for the RFID tag 5, and the RFID tag 5 and the IC chip 6 are supplied with operating power. Further, the command signal of the transmission wave is demodulated by the demodulation unit in the RFID tag 5 or the IC chip 6. The control unit in the RFID tag 5 or the IC chip 6 processes data from the instruction content of the demodulated command signal, and instructs to update or write the tag information to the memory of the IC chip 6 or both. Then, a response wave obtained by modulating the read signal output from the memory of the IC chip 6 by the modulation unit according to the instruction of the control unit is transmitted from the antenna 6a to the antenna 14 of the RFID reader / writer 13 via the analog unit of the RFID tag 5. Then, the RFID reader / writer 13 receives the read signal and obtains desired information.

  In this way, the identification number can be easily obtained from the animal 8 to be managed. Furthermore, since the animal ear tag RFID tag (RFID tag 5) according to the first embodiment is printed with an ID or a barcode representing an identification number, the RFID tag is read by an optical reading means such as a barcode reader. The identification number can also be obtained from the print on 5. In this case, a handy terminal (handy type RFID reader / writer and optical reading means) in which the optical reading means and the RFID reader / writer 13 are integrated may be used. Therefore, the animal ear tag RFID tag according to the first embodiment can obtain the identification number of the animal 8 to be managed even if the RFID tag 5 breaks down after manufacture, and even if the RFID tag 5 is stained. The identification number of the animal 8 to be managed can be obtained. Note that the RFID tag 5 is coated with a protective layer 7. In other words, the dirt on the RFID tag 5 is dirty on the protective layer 7 and can be easily cleaned by wiping. This is because even when a detergent is used for wiping, even a detergent that cannot be used on the printed surface of the RFID tag 5 due to problems such as disappearance of prints or fouling, it can be used as long as it can be used for the protective layer 7. I mean.
