Description

  The present invention relates to an electronic tag control device, an electronic tag, and a base station.

  Conventionally, in order to manage goods such as merchandise displayed in a store or products stored in a warehouse, the manager goes to the store or warehouse, counts the goods or products, etc. The number of sales and sales were calculated.

  Patent Document 1 discloses a merchandise management system using an electronic tag (identification tag) having an identifier for facilitating the above management. In this product management system, a response type identification tag capable of wireless communication with the product management device is attached to each product. These identification tags transmit different signals to the product management apparatus.

  For example, assuming that identification tags are pasted on products A and B that are for sale in the store, the product management device sends different data to the identification tags attached to the products A and B, respectively. To do. Then, the identification tag attached to the product A and the product B receives the data transmitted from the product management device, and transmits a response signal to the product management device. This response signal includes product information such as the product name, price, and shelf number on which the product is displayed.

  When organizing a large number of products with identification tags attached, the administrator selects the product from the product group displayed on the display unit of the product management device in order to collect product information of the products to be organized. To do. Then, a predetermined command for the selected product is transmitted from the product management apparatus to the identification tag. The identification tag attached to the product receives a command transmitted from the product management device, and determines whether the received command corresponds to its own identification tag. When the identification tag determines that the command corresponds to its own identification tag, the identification tag transmits a response signal to the product management device. The merchandise management apparatus can instantly calculate the quantity purchased, the quantity sold, the sales, etc. of a large number of merchandise by processing the response signal transmitted from the identification tag.

  By the way, the above-described merchandise management system does not have a function of detecting movement when equipment located in a specific room in the company, for example, a notebook PC is moved to another room. In addition, this system cannot warn even if an employee takes a notebook PC home.

  For example, in order to prevent unauthorized take-out of a notebook PC, there are devices that sound a warning sound when the notebook PC is physically fixed and this fixing is illegally released. Since a complicated operation such as releasing or re-fixing this fixing is necessary, the use of this fixing device is inconvenient and does not match the original purpose of use of the notebook PC.

  In addition, when managing a product in a warehouse using the above-described product management system, if there is a product at a predetermined position number of a warehouse shelf, the management can be smoothly performed. However, if the manager mistakenly places a product on another shelf, there is no way to track the product later, and the entire warehouse must be inspected to find one product.

  Furthermore, the identification tag used in the above-described merchandise management system cannot scan the information stored in the identification tag unless the handy terminal that is the merchandise management apparatus is in proximity. If the strength of the electromagnetic wave used for wireless communication between the identification tag and the handy terminal is increased, the scanning can be performed even if the distance between the identification tag and the handy terminal is large, but it may affect the human body. Is not preferable. That is, for merchandise management, it is desirable to use electromagnetic waves having a strength that can be scanned far and does not affect the human body.

  In recent years, shoplifting and theft in stores have frequently occurred. If an object detection device (for example, Patent Document 2) using electromagnetic waves is installed in a store in order to prevent shoplifting or theft, costs increase. In addition, if the store is large, it is difficult to install an object detection device at the entrance of the store because of the structure of the building or in terms of cost, and a loophole is created. Furthermore, shoplifting and theft cannot be completely prevented even if guards are arranged in the store.

  The merchandise management system described in Patent Document 1 can calculate the number of merchandise purchased, the quantity sold, and the sales, but cannot solve the above-described problem.

  Therefore, the present invention solves such a problem, and can provide an electronic tag control device, an electronic tag, and a base station that can easily manage goods at low cost and prevent shoplifting and theft of goods at low cost. The purpose is to provide.

  In order to solve the above-described problem, an electronic tag control apparatus according to the present invention includes an electronic device having a plurality of base stations having different propagation areas and a display unit and performing wireless communication with any of the plurality of base stations. Used in an electronic tag system comprising a tag and an electronic tag control device that manages a management target to which the electronic tag is attached in association with the electronic tag and a base station of a communication partner of the electronic tag. The electronic tag control device transmits display information to be displayed on the electronic tag to the electronic tag via a base station of a communication partner of the electronic tag.

  According to the present invention, the article can be easily managed at low cost, and shoplifting and theft can be prevented.

Hereinafter, an electronic tag system according to the present invention will be described with reference to the drawings.
<First Embodiment>
[Configuration Example of Electronic Bill System 100]
First, a configuration example of the electronic tag system 100 according to the first embodiment will be described. As shown in FIG. 1, the electronic tag system 100 includes an electronic tag 1 and an electronic tag control device 2.

  A strong adhesive is applied to the back surface of the electronic tag 1, and the electronic tag 1 is directly attached to the fixture 3 for use. In FIG. 1, electronic tags 1a, 1b, 1c, 1d, 1e, 1f, and 1g are attached to fixtures 3a, 3b, 3c, 3d, 3e, 3f, and 3g, respectively. Each of the electronic tags 1a to 1g has a unique identifier.

  For example, as shown in FIG. 2A, an electronic tag 1a is attached to a predetermined portion of a notebook computer that is an example of the equipment 3a. As shown in FIG. 2B, an electronic tag 1b is attached to a predetermined location of a portable information terminal device that is an example of the equipment 3b. Furthermore, as shown in FIG. 2C, an electronic tag 1c is attached to a predetermined portion of a box which is an example of the fixture 3c.

  Returning to FIG. 1, the electronic tag control device 2 includes an identification information generation unit 201 and base stations 211, 212,. , N are connected to the identification information generation unit 201. A personal computer (hereinafter referred to as PC 5) is connected to the PC controller 4.

  The PC controller 4 is connected to a plurality of PCs 5 and inputs commands output from the PCs 5 to the identification information generation unit 201. The PC controller 4 also has a function of a line concentrator (HUB).

  The identification information generation unit 201 receives a command output from the PC 5 via the PC controller 4 and generates predetermined information based on the received command. The predetermined information includes image information displayed on the electronic tag 1 and identification information of the electronic tag 1. The identification information generation unit 201 outputs the generated information to the base stations 211, 212,.

  Incidentally, in the identification information, when the electronic tags 1a to 1g are grouped (for example, in FIG. 1, the electronic tags 1a, 1b and 1c are set to the group A indicated by the broken line, and the electronic tags 1d and 1e are indicated by the broken line. Group ID that is an identifier of the group, an address ID that is a unique identifier of the electronic tags 1a to 1g, and equipment. Name, management number, administrator and storage location. This identification information is browsed, updated, changed, etc. by the PC 5.

  The base stations 211, 212,..., N modulate the information output from the identification information generation unit 201 and transmit it as a radio wave within a predetermined propagation area. For example, in FIG. 1, the base station 211 modulates the identification information including the group ID of the group A output from the identification information generation unit 201 and transmits the modulated information as a radio wave in the propagation area of the group A. The base station 212 modulates the identification information including the group ID of the group B output from the identification information generation unit 201 and transmits the modulated information as a radio wave in the propagation area of the group B. The base station N modulates the identification information including the group ID of the group N output from the identification information generation unit 201 and transmits the modulated information as a radio wave within the propagation region of the group N.

  In the electronic tags 1a to 1g, group IDs corresponding to the groups A, B,. For example, group IDs corresponding to group A are stored in the electronic tags 1a, 1b, 1c, group IDs corresponding to group B are stored in the electronic tags 1d, 1e, and group N is stored in the electronic tags 1f, 1g. Corresponding group IDs are stored. The group ID is a different identifier for each of the groups A, B,.

  The electronic tags 1a to 1g receive the identification information including the group IDs of the groups A, B,..., N transmitted by the base stations 211, 212, ..., N and are included in the received identification information. It is determined whether or not the group IDs of the groups A, B,. When it is determined that the group ID included in the identification information does not match the group ID of the electronic tag 1, the electronic tag 1 notifies that the electronic tag 1 has moved from the predetermined propagation area to the outside of the propagation area. .

  For example, attention is paid to the electronic tag 1a in which the group ID corresponding to the group A is stored. As shown in FIG. 3, on the premise that an electronic tag 1a having a group ID corresponding to group A (for example, an office in a company) is attached to the fixture 3a (for example, a notebook PC), When in the group A, the electronic tag 1a can receive the identification information including the group ID corresponding to the group A transmitted from the base station 211. The group ID of the identification information received by the electronic tag 1a matches the group ID of the electronic tag 1a.

  When the equipment 3a is taken out from the group A into a group outside the group A (for example, a conference room in the company), the electronic tag 1a cannot receive the identification information transmitted from the base station 211, and the base station 212 The identification information including the group ID corresponding to the group B to be transmitted is received. The group ID of the identification information received by the electronic tag 1a does not match the group ID of the electronic tag 1a. Notify that it has been moved.

  This notification is, for example, by sound emission by the buzzer 14 described later in FIG. 4 or light emission by the LED 15. Incidentally, even if the equipment 3a moves to the overlapping area of the group A and the group B shown in FIGS. 1 and 3, the electronic tag 1a can receive the identification information transmitted from the base station 211. Does not emit sound or emit light by the LED 15.

  Thereby, when the electronic tag 1 moves out of the propagation area of the identification information transmitted by the base stations 211, 212,..., N, the buzzer 14 emits sound and the LED 15 emits light. When the electronic tag 1 is attached to the fixture 3, it can be notified that the fixture 3 has moved from the propagation area to the outside of the propagation area. As a result, the equipment 3 can be easily managed.

[Configuration example of electronic tag 1]
Next, a configuration example of the electronic card 1 will be described. As shown in FIG. 4, the electronic tag 1 is an example of a main body unit 11, a built-in antenna 12 that is an example of a reception unit and a transmission unit, a liquid crystal display (hereinafter referred to as an LCD 13) that is an example of a display unit, and an example of a sound emitting unit. A buzzer 14 and a light emitting diode (hereinafter referred to as LED 15) which is an example of a light emitting unit are configured. In addition, the electronic tag 1 includes a power supply unit configured by a battery or the like (not shown), and power is supplied from the power supply unit to each of the above-described units to operate each unit.

  The main body 11 is a small casing having a length of about 2 cm, a width of about 10 cm, and a thickness of 1 to 2 cm. The main body 11 is made of, for example, a synthetic resin such as polyethylene, polypropylene, and polyvinyl chloride, and is formed by blow molding, injection molding, or the like.

  The main body 11 is provided with a built-in antenna 12, an LCD 13, a buzzer 14, and an LED 15. A barcode 16 is printed on the surface of the main body 11. The bar code 16 is obtained by encoding the management number of the equipment 3.

  The built-in antenna 12 receives the image information and the identification information transmitted from the electronic tag control device 2, and transmits the confirmation signal generated by the confirmation signal generation unit 25 described later with reference to FIG. . The built-in antenna 12 is built in the main body 11 and can transmit and receive high-frequency radio waves in the GHz band, for example, and is made of ferrite.

  The LCD 13 displays characters, code symbols, and the like. For example, the LCD 13 displays the name, management number, administrator, storage location, and the like of the fixture 3 attached to the electronic tag 1 based on the image information and identification information received by the built-in antenna 12.

  Instead of the LCD 13, a flat panel display such as an organic EL, an inorganic EL, and electronic paper may be used.

  The buzzer 14 is used when the electronic tag 1 cannot receive the identification information, or when the group ID included in the identification information transmitted from the base stations 211, 212,... The sound is emitted when does not match. That is, the buzzer 14 notifies that the equipment 3 to which the electronic tag 1 is attached has moved out of the propagation area of the base stations 211, 212,.

  The buzzer 14 may emit sound continuously in time or may emit sound intermittently. Further, the buzzer 14 may be such that the volume increases stepwise every few seconds, for example. Thereby, even if it is a user who is hard to notice the sound emission of the buzzer 14, since the volume of the buzzer 14 increases gradually, it can be made to notice sound emission.

  Further, the buzzer 14 may emit various timbres. As a result, the timbre emitted by the buzzer 14 can be changed depending on the information received by the electronic tag 1. As a result, the user can audibly determine the information received by the electronic tag 1.

  For the buzzer 14, for example, a piezoelectric buzzer or a mechanical buzzer is used. The piezoelectric buzzer is manufactured by sticking a piezoelectric diaphragm made of ceramics to a metal plate. The piezoelectric diaphragm expands and contracts when an AC voltage is applied to the piezoelectric buzzer. By repeating this expansion and contraction, a continuous sound of the piezoelectric buzzer is generated.

  The mechanical buzzer includes an electromagnetic coil and an iron plate switch. The iron plate-like switch is a switch that is switched between a first position and a second position, and that allows current to flow through the electromagnetic coil at the first position and does not flow current through the electromagnetic coil at the second position. When a current is passed through the electromagnetic coil, the switch is switched from the first position to the second position by the magnetic force of the electromagnetic coil. When the switch is switched to the second position, no current flows through the electromagnetic coil and the magnetic force from the electromagnetic coil is lost, so that the switch returns to the first position again. Thus, the continuous sound of the mechanical buzzer is generated when the iron plate-like switch repeats switching between the first and second positions. By changing the size and shape of the iron plate switch, the volume and range of the buzzer can be changed.

  When the electronic tag 1 cannot receive the identification information, the LED 15 includes a group ID included in the identification information transmitted in the propagation area of the base stations 211, 212,. If the two do not match, light is emitted. That is, the LED 15 notifies that the fixture 3 to which the electronic tag 1 is attached has moved from the propagation area of the base stations 211, 212,.

  The LED 15 may emit light (turn on) continuously in time, or may emit light (flash) intermittently.

  The LED 15 may emit light along with the sound emitted from the buzzer 14. This ensures to the user that the fixture 3 has moved out of the propagation area of the base stations 211, 212,..., N compared to only sound emission by the buzzer 14 or light emission by the LED 15. Can be informed.

  The LED 15 may change the blinking interval, or may be three chips that emit light in the three primary colors of RGB (for example, red light emission is a chip made of AlGaAs or GaAsP, green light emission is InGaN / GaN / AlGaN, GaP, etc. And a blue light emitting chip having a chip made of SiC, ZnSe, GaN, or the like) may emit light in various colors. Thereby, the blinking interval and the emission color of the LED 15 can be changed according to the difference in information received by the electronic tag 1. As a result, the user can visually determine the information received by the electronic tag 1.

[Configuration example of control system of electronic tag 1]
Next, a configuration example of the control system of the electronic tag 1 will be described. As shown in FIG. 5, the electronic tag 1 includes a built-in antenna 12, an LCD 13, a buzzer 14, an LED 15, a CPU 17 as an example of a determination unit, a transmission / reception unit 18, a data acquisition unit 19, an image generation unit 20, an image storage unit 21, The LCD driver 22 includes a RAM 23 as an example of a storage unit, a ROM 24 as an example of a storage unit, and a confirmation signal generation unit 25.

  Built-in antenna 12, LCD 13, buzzer 14, LED 15, CPU 17, transmission / reception unit 18, data acquisition unit 19, image generation unit 20, image storage unit 21, LCD driver 22, RAM 23, ROM 24, and confirmation signal generation unit 25 are not shown. Mounted on an electronic circuit board.

  A transmission / reception unit 18 is connected to the built-in antenna 12. The transmission / reception unit 18 receives the identification information D1 (including information D2 related to the equipment name, management number, administrator and storage location, and information D3 related to the group ID) transmitted from the electronic tag control device 2 via the built-in antenna 12. Receive.

  The transmission / reception unit 18 outputs, to the data acquisition unit 19, information D <b> 2 related to the equipment name, management number, administrator, storage location, and the like among the received identification information D <b> 1, and outputs information D <b> 3 related to the group ID to the CPU 17. In addition, the transmission / reception unit 18 transmits a confirmation signal D8 generated by a confirmation signal generation unit 25, which will be described later, to the electronic tag control device 2 via the built-in antenna 12.

  A data acquisition unit 19 is connected to the transmission / reception unit 18. The data acquisition unit 19 acquires information D <b> 2 related to the equipment name, management number, administrator, storage location, and the like output from the transmission / reception unit 18, and outputs the information D <b> 2 to the CPU 17 and the image generation unit 20.

  An image generation unit 20 is connected to the data acquisition unit 19. The image generation unit 20 acquires information D2 relating to the name of the equipment, the management number, the administrator, the storage location, and the like output from the data acquisition unit 19. The image generation unit 20 generates image data D4 for one page (n rows and m columns display pixels that can be displayed on the LCD 13) based on the acquired information D2 on the name, management number, manager, storage location, and the like of the equipment. The generated image data D4 is output to the image storage unit 21.

  An image storage unit 21 is connected to the image generation unit 20. The image storage unit 21 stores the image data D4 output from the image generation unit 20.

  An LCD driver 22 is connected to the image generation unit 20. The image generation unit 20 reads the image data D4 stored in the image storage unit 21, and outputs the read image data D4 to the LCD driver 22. The LCD driver 22 acquires the image data D4 output by the image generation unit 20, and controls the LCD 13 based on the acquired image data D4.

  The LCD 13 is connected to the LCD driver 22. The LCD 13 displays an image based on the image data D4 acquired by the LCD driver 22. The LCD 13 displays, for example, the name of the equipment stored in the image data D4, the management number, the administrator and the storage location.

  The CPU 17 is connected to the transmission / reception unit 18, the data acquisition unit 19, the image storage unit 21, and the LCD driver 22. The CPU 17 controls each unit described above. A RAM 23 and a ROM 24 are connected to the CPU 17. The ROM 24 stores a control program for controlling the electronic tag 1 and information D5 regarding the group ID of the group to which the electronic tag 1 belongs. For example, the ROM 24 of the electronic tag 1a stores a group ID corresponding to the group A, and the ROM 24 of the electronic tag 1d stores a group ID corresponding to the group B.

  The CPU 17 acquires information D3 related to the group ID output by the transmission / reception unit 18. The CPU 17 stores information D3 related to the acquired group ID in the RAM 23. Then, the CPU 17 matches the information D3 related to the group ID received by the transmission / reception unit 18 and stored in the RAM 23 with the information D5 related to the group ID stored in the ROM 24 in advance. Determine whether or not.

  A buzzer 14 and an LED 15 are connected to the CPU 17. When the CPU 17 cannot receive the identification information D1 including the group ID transmitted from the electronic tag control device 2, the CPU 17 generates a warning signal D6 for emitting the buzzer 14 and for causing the LED 15 to emit light. The CPU 17 also generates the warning signal D6 when it determines that the information D3 related to the group ID received by the transmission / reception unit 18 and stored in the RAM 23 does not match the information D5 related to the group ID of the electronic tag 1 itself. To do. The CPU 17 outputs the generated warning signal D6 to the buzzer 14 and the LED 15. Then, the buzzer 14 emits sound and the LED 15 emits light.

  The confirmation signal generator 25 is connected to the CPU 17. When the CPU 17 determines that the information D3 related to the group ID received by the transmission / reception unit 18 and stored in the RAM 23 matches the information D5 related to the group ID of the electronic tag 1 itself, the CPU 17 generates a confirmation signal D8 indicating the determination result. The command signal D7 is output to the confirmation signal generator 25 so as to create it. When receiving the command signal D7 from the CPU 17, the confirmation signal generation unit 25 generates a confirmation signal D8 and outputs the generated confirmation signal D8 to the transmission / reception unit 18.

[Example of operation of electronic bill system 100]
Next, an operation example of the electronic tag system 100 will be described using a flowchart. As shown in FIG. 6, in step ST <b> 1, the identification information generation unit 201 included in the electronic tag control device 2 generates identification information including group IDs corresponding to the groups A, B,.

  The identification information generation unit 201 outputs the generated identification information to the base stations 211, 212,. For example, the identification information generation unit 201 outputs the identification information including the group ID corresponding to the group A to the base station 211, outputs the identification information including the group ID corresponding to the group B to the base station 212, Identification information including the corresponding group ID is output to the base station N.

  Shifting to step ST2, the base stations 211, 212,..., N acquire the identification information output from the identification information generation unit 201, modulate the acquired identification information, and use the predetermined propagation area as a radio wave. Send in. For example, the base station 211 transmits identification information including a group ID corresponding to the group A in the propagation area of the group A. The base station 212 transmits identification information including a group ID corresponding to the group B into the propagation area of the group B. The base station N transmits identification information including a group ID corresponding to the group N in the propagation area of the group N.

  In step ST3, the electronic tag 1 moves to step ST4 if the identification information transmitted as radio waves from the base stations 211, 212,... Move on to ST5.

  In step ST4, the CPU 17 of the electronic tag 1 determines whether or not the group ID included in the identification information received from the base stations 211, 212,..., N matches the group ID stored in the ROM 24. To do. If the group ID received from the base station 211, 212,..., N matches the group ID stored in the ROM 24, the process proceeds to step ST6, and if not, the process proceeds to step ST5.

  In step ST5, the electronic tag 1 is received from the base stations 211, 212,..., N when the identification information transmitted as radio waves from the base stations 211, 212,. When the group ID and the group ID stored in the ROM 24 do not match, a warning signal is generated and the generated warning signal is output to the buzzer 14 and / or the LED 15. Then, the buzzer 14 of the electronic card 1 emits sound and the LED 15 emits light. As a result, the user can be warned that the equipment 3 has moved out of the propagation area of the base stations 211, 212,.

  In step ST6, the CPU 17 generates a confirmation signal in the confirmation signal generator 25 when the group ID received from the base stations 211, 212,..., N matches the group ID stored in the ROM 24. Command signal is issued. The confirmation signal generator 25 receives a command signal from the CPU 17 and generates a confirmation signal. Then, the transmission / reception unit 18 transmits the confirmation signal generated by the confirmation signal generation unit 25 to the electronic tag control device 2.

  In step ST7, when the electronic tag control apparatus 2 can receive the confirmation signal transmitted from the transmitting / receiving unit 18 of the electronic tag 1, the electronic tag control apparatus 2 returns to step ST2 and returns to the base stations 211, 212,. , N again transmits identification information within a predetermined propagation area, and repeats the above-described operation. At this time, on the display device 5a connected to the PC 5, for example, as shown in FIG. 7A, the name of the equipment, the shelf number to be stored, the base station in charge, the storage location, and the owner are displayed. .

  When the electronic tag control device 2 cannot receive the confirmation signal transmitted from the transmission / reception unit 18 of the electronic tag 1, the electronic tag control device 2 proceeds to step ST8.

  In step ST8, since the electronic tag control device 2 has not received the confirmation signal transmitted from the electronic tag 1 after a predetermined time has passed since the identification information was transmitted, the electronic tag 1 is connected to the base stations 211, 212, .., N is determined to have moved from the propagation area to the outside of the propagation area, warning information is generated, and the generated warning information is output to the PC 5 via the PC controller 4.

  The PC 5 receives the warning information output from the electronic tag control device 2. Then, for example, as shown in FIG. 7B, a warning screen indicated by diagonal lines is displayed on the display device 5a connected to the PC 5 to warn that the equipment has moved from inside the propagation area to outside the propagation area. The That is, as shown in FIG. 3, the equipment 3 a having the group ID corresponding to the group A (for example, the notebook PC 1 manufactured by Company B of No. 3 shown in FIG. 7) is taken out from the group A to the group B. Sometimes, a warning sound and a warning light are emitted from the electronic tag 1a, but a warning screen is displayed on the display device 5a of the PC 5 in order to notify that the equipment 3a has been taken out from the group A to the group B.

  If the equipment 3 is to be taken out from the group A to the group B without emitting the sound from the buzzer 14 and emitting light from the LED 15, the group ID corresponding to the group B can be stored in the RAM 23 of the electronic card 1 from the PC 5 or the like. It ’s fine.

  By the way, in the past, an RFID system was attached to equipment, and when a security gate installed at the entrance / exit of the company was held with the equipment with the RFID attached, a warning sound was used. Warning cannot be given if equipment is taken out from an exit where a security gate is not installed. On the other hand, the electronic tag system 100 according to the present embodiment emits a warning sound or a warning light when it goes out of the propagation range of the base station, and a warning screen is also displayed on the display device 5a of the PC 5. Equipment can be managed reliably.

  Thus, according to the electronic tag system 100 according to the present embodiment, the plurality of electronic tags 1 have group IDs. The electronic tag control device 2 generates identification information including the group ID of the electronic tag 1 and stores the generated identification information in a predetermined propagation area (for example, groups A, B,..., N shown in FIG. 1). Send to. On the premise of this, each of the electronic bills 1 receives the identification information transmitted by the electronic tag control device 2, and determines whether or not the group ID included in the received identification information matches its own group ID. If the judgment result does not match, the fact that the electronic tag 1 has moved from the propagation area where the identification information is transmitted to the outside of the propagation area is notified by sound emission by the buzzer 14 or light emission by the LED 15.

  Accordingly, for example, when the electronic tag 1 is attached to the fixture 3, the fact that the fixture 3 has moved from the propagation area where the identification information is transmitted to the outside of the propagation area is notified by sound emission by the buzzer 14 or light emission by the LED 15. become able to. As a result, the fixture 3 can be easily managed at low cost.

  In a conventional electronic tag using RFID, information from the PC cannot be received unless the electronic tag is brought close to or in contact with a reader / writer connected to the PC. In addition, a conventional electronic tag using RFID can receive information from a PC even if the output of the reader / writer is increased. In this case, a strong electromagnetic wave is output from the reader / writer (for example, the output is About 10 mW), which may affect the human body. On the other hand, in the electronic tag system 100 according to the present embodiment, even if the electronic tag is separated from the base station by a predetermined distance, and even if the output of the base station is not increased (for example, the output is about 1 mW), Information can be received from the PC.

  In the present embodiment, the barcode 16 is printed on the main body 11. However, the present invention is not limited to this. The barcode is printed on paper or the like, and the printed paper is printed on the main body 11. It may be attached to the surface with an adhesive or the like.

  Further, in the present embodiment, only one LED 15 is provided on the electronic card 1, but the present invention is not limited to this, and a plurality of LEDs 15 having different emission colors may be provided. This can further visually warn the user.

  Further, in the present embodiment, the information D5 related to the group ID is stored in the ROM 24 of the electronic tag 1, but the present invention is not limited to this, and the information D5 may be stored in the RAM 23 and may be rewritten from the PC 5. As a result, the electronic tag 1 can be reused, for example, for other purposes.

  In the present embodiment, the electronic card 1 is provided with the image storage unit 21, but the present invention is not limited to this, and the image storage unit 21 has the function of the image storage unit 21 in the RAM 23 and / or the ROM 24. It may be deleted. Thereby, the cost of the electronic tag 1 can be reduced.

  In this embodiment, the electronic tag system 100 is applied to equipment management in a company. However, the electronic tag system 100 can also be applied to security management of products in a store. For example, the buzzer 14 and the LED 15 notify that the product in the store where the electronic tag 1 is attached has moved from the propagation area of the identification information (inside the store) to the outside of the propagation area (outside the store). Thereby, shoplifting and theft can be prevented at low cost.

  Further, in the present embodiment, when the electronic tag control device 2 does not receive the confirmation signal D8 from the electronic tag 1, the warning screen is displayed on the display device 5a (FIG. 7B). Not only, but when the electronic tag 1 moves from the propagation area to the outside of the propagation area, the buzzer 14 and the LED 15 notify the electronic tag 1, and the electronic tag 1 transmits its address ID to the electronic tag control device 2. The display device 5a may display a warning screen indicating that the electronic tag has moved from inside the propagation area to outside the propagation area.

<Second Embodiment>
In the present embodiment, an electronic tag system 100A composed of an electronic tag 6 that does not include the LCD 13 of the electronic tag 1 described in the first embodiment will be described. Components having the same names and reference numerals as those of the first embodiment have the same functions, and thus description thereof is omitted.

[Configuration example of electronic bill system 100A]
First, a configuration example of an electronic tag system 100A according to the second embodiment will be described. As shown in FIG. 8, the electronic tag system 100 </ b> A includes an electronic tag 6 and an electronic tag control device 2. Further, the electronic tag system 100A includes a handy terminal 40.

  As with the electronic tag 1, a strong adhesive is applied to the back side of the electronic tag 6, and the electronic tag 6 is directly attached to a product 8 and a file 9 described later with reference to FIGS. Is done. In FIG. 8, electronic tags 6a, 6b, 6c, 6d, 6e, 6f, and 6g are attached to the products 8a, 8b, 8c, 8d, 8e, 8f, and 8g, respectively.

  The handy terminal 40 is a portable terminal for managing the product 8 and the file 9 attached to the electronic tag 6. The handy terminal can communicate with the base stations 211, 212,..., N, and can browse, update, and change the identification information, and has the same function as the PC 5. That is, the handy terminal 40 can be carried by the user and manage the product 8 and the file 9.

  The detailed description of the PC controller 4, the PC 5, the identification information generation unit 201, and the base stations 211, 212,..., N is the same as that described with reference to FIG.

[Configuration example of electronic tag 6]
Next, a configuration example of the electronic bill 6 will be described. As shown in FIG. 9, the electronic tag 6 includes a main body 11 </ b> A, a built-in antenna 12, a buzzer 14, and an LED 15. In addition, the electronic tag 6 includes a power supply unit configured by a battery or the like (not shown), and power is supplied from the power supply unit to each of the above-described units to operate each unit.

  Unlike the electronic tag 1 described in the first embodiment, the main body part 11A is not provided with the LCD 13, so that the main body part 11A is approximately 1 cm in length, approximately 10 cm in width, and 0.5 cm in thickness. And a smaller casing. The main body 11A is made of, for example, a synthetic resin such as polyethylene, polypropylene, and polyvinyl chloride, and is formed by blow molding, injection molding, or the like.

  The main body 11A is provided with a built-in antenna 12, a buzzer 14, and an LED 15. A barcode 16 is printed on the surface of the main body 11A.

  The built-in antenna 12, the buzzer 14, and the LED 15 are the same as those described with reference to FIG.

[Configuration example of control system of electronic tag 6]
Next, a configuration example of the control system of the electronic tag 6 will be described. As shown in FIG. 10, the electronic tag 6 includes a built-in antenna 12, a buzzer 14, an LED 15, a CPU 17 </ b> A, a RAM 23, a ROM 24, a receiving unit 26, and an off signal generating unit 27.

  The built-in antenna 12, the buzzer 14, the LED 15, the CPU 17A, the RAM 23, the ROM 24, the receiving unit 26, and the off signal generating unit 27 are each mounted on an electronic circuit board (not shown).

  Since the electronic tag 6 is not provided with the LCD 13, the data acquisition unit 19, the image generation unit 20, the image storage unit 21, and the LCD driver 22 described in FIG. 5 are unnecessary.

  A receiving unit 26 is connected to the built-in antenna 12. The receiving unit 26 receives the identification information D11 transmitted from the electronic tag control device 2 and including the address ID that is a unique identifier of the electronic tag 6 via the built-in antenna 12. The receiving unit 26 also receives a prohibition request signal D12 for prohibiting sound emission from the buzzer 14 and light emission from the LED 15 via the built-in antenna 12. Then, the reception unit 26 outputs the received identification information D11 to the CPU 17A, and outputs the received prohibition request signal D12 to the off signal generation unit 27. The prohibition request signal D12 is generated by the PC 5 or the handy terminal 40 and transmitted to the electronic tag 6.

  An off signal generation unit 27 is connected to the reception unit 26. The off signal generation unit 27 acquires the prohibition request signal D12 output from the reception unit 26, and generates an off signal D13 based on the acquired prohibition request signal D12. The off signal generation unit 27 outputs the generated off signal D13 to the CPU 17A.

  The off signal D13 is a signal for avoiding a warning due to sound emission of the buzzer 14 or light emission of the LED 15. In order to move the file 9 or the product 8 from within the propagation area of the radio wave transmitted by the base stations 211, 212, ..., N shown in FIG. 1, for example, the prohibition request signal D12 is sent from the PC 5 or the handy terminal 40. Transmit to the electronic bill 6. Then, the off signal generation unit 27 of the electronic tag 6 generates an off signal D13 based on the prohibition request signal D12 and outputs it to the CPU 17A. When the CPU 17A receives the off signal D13, the CPU 17A controls the electronic card 6 so that the buzzer 14 does not emit sound and the LED 15 does not emit light.

  A CPU 17 </ b> A is connected to the reception unit 26 and the off signal generation unit 27. The CPU 17A controls the reception unit 26 and the off signal generation unit 27. A RAM 23 and a ROM 24 are connected to the CPU 17A. The ROM 24 stores a control program for controlling the electronic tag 6 and information D14 regarding the address ID of the electronic tag 6.

  The CPU 17A acquires the identification information D11 related to the address ID output from the receiving unit 26. The CPU 17A stores identification information D11 related to the acquired address ID in the RAM 23. Then, the CPU 17A matches the identification information D11 related to the address ID received by the receiving unit 26 and stored in the RAM 23 with the information D14 related to the address ID stored in the ROM 24 in advance. Judge whether to do.

  A buzzer 14 and an LED 15 are connected to the CPU 17A. When the CPU 17A determines that the identification information D11 related to the address ID received by the receiving unit 26 and stored in the RAM 23 matches the information D14 related to the address ID of the electronic tag 6 itself, the CPU 17A emits the buzzer 14 And a warning signal D15 for causing the LED 15 to emit light. The CPU 17A outputs the generated warning signal D15 to the buzzer 14 and the LED 15. Then, the buzzer 14 emits sound and the LED 15 emits light.

  Further, the CPU 17A acquires the off signal D13 output from the off signal generation unit 27. When acquiring the off signal D13, the CPU 17A does not generate the warning signal D15. Therefore, when the off signal D13 is generated, the buzzer 14 does not emit sound and the LED 15 does not emit light.

[Example of operation of electronic bill system 100A]
Next, an operation example of the electronic tag system 100A will be described using a flowchart. It is assumed that the address ID is stored in advance in the electronic tags 6a to 6g shown in FIG.

  As shown in FIG. 11, in step ST11, the identification information generation unit 201 included in the electronic tag control device 2 generates identification information including address IDs stored in the electronic tags 6a to 6g, respectively.

  The identification information generation unit 201 outputs the generated identification information to the base stations 211, 212,. For example, the identification information generation unit 201 outputs identification information including address IDs corresponding to the electronic tags 6a, 6b, and 6c to the base station 211, and uses the identification information including address IDs corresponding to the electronic tags 6d and 6e as base information. The information is output to the station 212, and the identification information including the address ID corresponding to the electronic tags 6f and 6g is output to the base station N.

  Shifting to step ST12, the base stations 211, 212,..., N acquire the identification information output from the identification information generation unit 201, modulate the acquired identification information, and use the predetermined propagation region as a radio wave. Send in. For example, the base station 211 transmits identification information including an address ID corresponding to the electronic tags 6a, 6b, and 6c into the propagation area of the group A. The base station 212 transmits identification information including the address ID corresponding to the electronic tags 6d and 6e into the propagation area of the group B. The base station N transmits identification information including the group ID corresponding to the electronic tags 6f and 6g into the propagation area of the group N.

  In step ST13, the electronic tag 6 moves to step ST14 when the identification information transmitted as radio waves from the base stations 211, 212,..., N can be received. End the operation.

  In step ST14, the CPU 17A of the electronic tag 6 determines whether or not the address ID included in the identification information received from the base stations 211, 212,..., N matches the address ID stored in the ROM 24. To do. When the address ID received from the base station 211, 212,..., N matches the address ID stored in the ROM 24, the process proceeds to step ST15.

  In step ST15, the CPU 17A proceeds to step ST16 when the off signal is output from the off signal generation unit 27 and the output off signal is acquired, and the operation is performed when the off signal is not acquired. Exit.

  In step ST16, the electronic tag 6 warns when the address ID received from the base stations 211, 212,... N matches the address ID stored in the ROM 24 and the off signal is not acquired. A signal is generated, and the generated warning signal is output to the buzzer 14 and / or the LED 15. Then, the buzzer 14 emits sound and the LED 15 emits light. Thereby, the position of the product 8 can be notified to the user. As a result, even if the location of the product 8 is not known, the product 8 can be easily found.

  For example, as shown in FIG. 12, it is assumed that a desired product 8 is found from a plurality of products placed on a product shelf 30 such as in a warehouse. A user carrying the handy terminal 40 transmits identification information including the address ID of the electronic tag 6 attached to the desired product 8 from the handy terminal 40 into the propagation area. Then, when the desired product 8 exists in the propagation area, the electronic tag 6 attached to the product 8 receives the identification information. Then, the electronic tag 6 emits the buzzer 14 and causes the LED 15 to emit light when the address ID included in the received identification information matches the address ID of the electronic tag 6 and no off signal is generated. Thereby, the desired product 8 can be easily found.

  Further, for example, as shown in FIG. 13, it is assumed that a desired file 9 is searched from a plurality of files stored in a file shelf 31 such as in a company. Also in this case, as in the case described with reference to FIG. 12 described above, by transmitting identification information including the address ID from the handy terminal 40 into the propagation area, if the desired file 9 exists in the propagation area, The electronic tag 6 attached to the file 9 receives the identification information. Then, the electronic tag 6 emits the buzzer 14 and causes the LED 15 to emit light when the address ID included in the received identification information matches the address ID of the electronic tag 6 and no off signal is generated. Thereby, a desired file 9 can be easily found.

  As described above, according to the electronic tag system 100A according to the present embodiment, the plurality of electronic tags 6 have the address ID. The electronic tag control device 2 generates identification information including the address ID of the electronic tag 6 and stores the generated identification information in a predetermined propagation area (for example, groups A, B,..., N shown in FIG. 8). Send to. On the premise of this, each of the electronic bills 6 receives the identification information transmitted by the electronic tag control device 2, and determines whether or not the address ID included in the received identification information matches its own address ID. If the determination result matches, the position of the electronic tag 6 is notified by sound emission by the buzzer 14 or light emission by the LED 15.

  Thus, for example, when the electronic tag 6 is attached to the product 8 or the file 9, even if the location of the product 8 or the file 9 is not known, the buzzer of the electronic tag 6 is identified by the identification information from the electronic tag control device 2. 14 emits sound and the LED 15 emits light, so that the product 8 and the file 9 can be easily found.

Therefore, the description thereof will be omitted, and the switch 28 and the button 29 will be described.

  When the knob 28a of the switch 28 is moved from the ON side to the OFF side, the electronic card 7 is switched from the ON state to the OFF state. When the electronic tag 7 is turned off, the power supply from the power supply unit is cut off. Before that, the switch 28 outputs an OFF signal D21 for notifying that the electronic tag 7 is turned off to the CPU 17B. To do. Then, the CPU 17B receives the OFF signal D21 output from the switch 28 and transmits it to the base stations 211, 212,..., N and the handy terminal 40 via the transmission / reception unit 18 and the built-in antenna 12.

  The base stations 211, 212,..., N output an OFF signal D21 from the CPU 17B to the PC 5 to display on the display device 5a of the PC 5 that the electronic bill 7 has been turned off. In addition, the handy terminal 40 displays that the electronic tag 7 has been turned off on the display unit of the handy terminal 40 based on the OFF signal D21 from the CPU 17B. Thereby, the ON / OFF state of the electronic card 7 can be managed by the PC 5 and the handy terminal 40.

  When the button 29 is pressed, the button 29 outputs, for example, product abnormality information D22 notifying the abnormality of the product 8 to which the electronic tag 7 is attached to the CPU 17B. Then, the CPU 17B receives the product abnormality information D22 output from the button 29 and transmits it to the base stations 211, 212,..., N and the handy terminal 40 via the transmission / reception unit 18 and the built-in antenna 12.

Thereby, the normal / abnormal state of the product 8 can be managed by the PC 5 and the handy terminal 40.

[Usage example of electronic bill system 100B]
Next, a usage example of the electronic tag system 100B will be described. As shown in FIG. 17, it is assumed that an electronic tag 7 is attached to a product 8 such as a jacket displayed in the store, and the electronic tag 7 and the base station 211 and the handy terminal 40 can communicate with each other. .

  As shown in FIG. 18, the LCD 13 of the electronic tag 7 normally displays a screen indicating the price of the product 8 “¥ 32,500”.

  For example, if the product 8 has an abnormality such as a scratch or a dirt, and a salesperson notices this abnormality, the product 8 is cleared in the stock room or the like, and the fact that the product 8 is abnormal and cannot be sold is written in the slip file. It is necessary to perform complicated work. However, in the electronic tag system 100B, when the salesperson notices an abnormality in the product 8, pressing the button 29 on the electronic tag 7 eliminates the need for the above-described complicated work.

  That is, when the button 29 is pressed by the salesperson, the product abnormality information D22 is output to the CPU 17B, and the CPU 17B transmits the product abnormality information D22 to the PC 5 and the handy terminal 40, and as shown in FIG. Display the screen “Cancel sale”. When the PC 5 or the handy terminal 40 receives the product abnormality information D22, a product abnormality screen based on the product abnormality information D22 is displayed on the display device 5a, and the product abnormality information D22 is stored in the storage unit of the PC 5 as needed. Thus, the product 8 can be easily managed.

  Instead of pressing the button 29, the handy terminal 40 may be operated to display the “Sales Cancel” screen on the LCD 13 and to transmit the product abnormality information D22 from the electronic tag 7 to the PC 5.

  Further, for example, even when a salesperson negotiates a price with a customer, the electronic tag system 100B can be utilized. That is, as a result of price negotiation with the customer, when the price of only a certain product 8 is reduced, the salesperson operates the handy terminal 40 and the electronic tag attached to the reduced product 8 as shown in FIG. 7 is displayed on the LCD 13 with a reduced price of “¥ 27,500”, and information indicating the reduced price is transmitted from the electronic tag 7 to the PC 5. Incidentally, since the address ID, which is its own identifier, is stored in the electronic tag 7, only the LCD 13 of the electronic tag 7 can display the above-described display. Thereby, it can be managed by the PC 5 that the price of the product 8 has been reduced by the price negotiation with the customer.

  In addition, the electronic bill system 100B can be used even in a situation where a so-called time service is performed in which the price of a product is lowered at a predetermined time. That is, the salesperson operates the PC 5 and the handy terminal 40 to display the time service “30% OFF only from now until closing time” on the LCD 13 as shown in FIG. Information indicating that the price has been reduced by the time service is transmitted. Thus, the PC 5 can manage that the price of the product 8 has been reduced by the time service.

  In addition, when it is desired to reduce the price of only a predetermined product, for example, only the product in the group A shown in FIG. 14, information is transmitted from the PC 5 or the handy terminal 40 only to the electronic tag 7 having the group ID of the group A. It ’s fine.

  Furthermore, by managing the stock quantity of the product 8 using the PC 5 or the handy terminal 40, the stock quantity can be displayed on the LCD 13. For example, when the number of stocks of the product managed by the PC 5 or the handy terminal 40 is two, as shown in FIG. 22, a screen “Only the remaining two” can be displayed on the LCD 13 in real time. it can. Thereby, the stock quantity of the goods 8 can be grasped in real time in the store.

  In addition to displaying the above information on the LCD 13, it is also possible to display store information. For example, as shown in FIG. 23, by operating the PC 5 or the handy terminal 40, the LCD 13 can display information about the store “4/1 to 4/7 all-item half price sale”. Store information may be transmitted from the PC 5 or the handy terminal 40 to all of the electronic tags 7 attached to the products 8 in the store, and since the address ID and group ID are stored in the electronic tag 7, a predetermined information It is also possible to transmit store information only to a group or a predetermined product.
