Description

  The present invention relates to a position information management system for managing articles to be managed using a wireless tag, a position information management method using the position information management system, and a wireless tag used in the position information management system.

  FIG. 7 shows a conventional management system 16 for managing the vehicle 2 with the vehicle number card 5. In this management system 16, the number of vehicles 2 managed in the vehicle management area 13 may be several hundred to several thousand, and several tens of thousands may be managed on a large scale. With reference to FIG. 7, the management method of the vehicle 2 by the conventional management system 16 is demonstrated. FIG. 7 shows a period from when one vehicle 2 is carried into the vehicle management area 13 until it is carried out from the vehicle management area 13. The vehicle 2 is provided with symbols (2a) to (2f) according to the position of the vehicle 2.

  First, the case where the vehicle information of the vehicle 2 is registered in the server 10b will be described with reference to the vehicle 2 (2e). Before carrying the vehicle 2 into the vehicle management area 13, the vehicle information of the vehicle 2 carried into the vehicle management area 13 is registered in the server 10b. For example, when the vehicle management area 13 is a venue for buying and selling vehicles, the body number, vehicle type, year, color, mileage, accident history, etc. are registered in the server 10b as vehicle information. Simultaneously with this registration, the card number of the vehicle number card 5 and the parking position of the vehicle 2 are registered in the server 10b. By posting the vehicle number card 5 on the vehicle 2, the vehicle 2, the parking position of the vehicle 2, the card number of the vehicle number card 5, and the vehicle information registered in the server 10b are linked.

  The vehicle number card 5 is a card on which a card number is printed in advance, or is assigned with a card number when vehicle information is registered in the server 10b, and the vehicle number card 5 (or vehicle information card) is printed by a printer. Use as a print.

  Next, a case where the vehicle 2 is carried into the vehicle management area 13 will be described with reference to the vehicles 2 (2b) to (2d). The driver or the manager 3 a posts the vehicle number card 5 on the corresponding vehicle 2 and causes the vehicle 2 to enter the vehicle management area 13. The driver or the manager 3a carries the vehicle 2 (2c) from the entrance gate 12a into the vehicle management area 13, and moves the vehicle 2 (2c) to a parking position determined in advance with respect to the card number of the vehicle number card 5. And park. Thus, the vehicle 2 (2b) carried into the vehicle management area 13 is parked at the parking position registered in the server 10b based on the parking position described in the vehicle number card 5.

  Furthermore, the case where the vehicle 2 is carried out from the vehicle management area 13 is demonstrated with reference to vehicle 2 (2a), (2b), (2f). When carrying out the vehicle 2, the driver or the manager 3 b specifies the parking position of the vehicle 2 (2 b) from information on a predetermined parking position according to the card number described in the vehicle number card 5 of the corresponding vehicle 2. After specifying the parking position of the vehicle 2 (2 b), the vehicle 2 is picked up and the vehicle 2 (2 a) is left from the vehicle management area 13. After leaving the vehicle, the vehicle number card 5 is returned, and the driver or administrator 3c accesses the server 10b, and the server 10b performs the exit completion processing for the vehicle 2 (2f).

  In such a management system 16, when going to the vehicle management area 13 for checking the vehicle 2 or going to carry out the vehicle 2, the vehicle 2 is parked in accordance with the card number described in the vehicle number card 5. It is assumed that the vehicle is parked at the position. If the case where the vehicle 2 is moved in the vehicle management area 13 is considered, the parking position of the vehicle 2 can be searched from the card number by updating the parking position information registered in the server 10b.

  However, if the vehicle 2 is moved and the parking position information of the server 10b is not updated, or if the vehicle 2 is not parked at a predetermined parking position from the beginning, the target vehicle 2 may not be easily found. . In a management system with a large number of managed units, it may take a long time to search for the vehicle 2.

  In order to solve the above problem, a method of collecting and managing vehicle position information using a wireless tag has been proposed (for example, Patent Document 1).

  FIG. 8 shows a configuration of a wireless tag 4a according to the prior art. The tag ID of the wireless tag 4a (or a number unique to the wireless tag 4a such as a network address) is displayed as a tag ID 27 on a label attached to the surface of the wireless tag 4a. The tag ID 27 is written in advance in the nonvolatile memory 26 in the wireless tag 4a. The CPU unit 22 of the wireless tag 4 a transmits the tag ID 28 written in the nonvolatile memory 26 via the wireless unit 21. The writing of the tag ID 28 to the nonvolatile memory 26 and the label affixing operation of the tag ID 27 are generally performed during the manufacturing process of the wireless tag 4a or the inspection process of the wireless tag 4a.

  FIG. 9 shows a conventional management system 17 using the wireless tag 4a. FIG. 9 shows a period from when one vehicle 2 is carried into the vehicle management area 13 until it is carried out from the vehicle management area 13. The vehicle 2 is provided with symbols (2a) to (2f) according to the position of the vehicle 2.

  First, the case where the vehicle information of the vehicle 2 is registered in the server 10c will be described with reference to the vehicle 2 (2e). When the vehicle 2 is carried into the vehicle management area 13, the vehicle information of the vehicle 2 is registered in the server 10c. At the time of registration, the card number of the vehicle number card 5, the parking position of the vehicle 2, and the tag ID of the wireless tag 4a are registered in the server 10c. The tag ID of the wireless tag 4a is registered in advance in the wireless tag 4a, and the tag ID is also pasted on the surface of the wireless tag 4a with a display label or a barcode by a character string. When the vehicle information is registered in the server 10c, the tag ID of the wireless tag 4a is also registered at the same time, so that the vehicle 2, the card number of the vehicle number card 5, the vehicle information registered in the server 10c, and the wireless tag 4a Is associated with the tag ID. After these pieces of information are linked, the vehicle 2, the vehicle number card 5, and the wireless tag 4a are set and managed so that they are not separated thereafter.

  The wireless tag 4a includes means for notifying the server 10c of the position information and tag ID of the wireless tag 4a. The notified position information of the wireless tag 4a is collected by the server 10c as position information of the vehicle 2 on which the wireless tag 4a is mounted. The vehicle number card 5 is used by the driver or the manager 3b to identify the corresponding vehicle 2 by the card number.

  The vehicle 2 that has been registered in the server 10c is carried into the vehicle management area 13 as in the management system 16 shown in FIG.

  When the position of the vehicle 2 to which the wireless tag 4a is attached is specified, the position information of the wireless tag 4a acquired by the wireless tag 4a is transmitted from the wireless master device 7 through the network 9 through a pre-registered tag ID (or network address). Etc.) and the server 10c. Based on the signal transmitted from the wireless tag 4a, the server 10c determines the position where the vehicle 2 is parked in the vehicle management area 13, and updates the parking position information of the vehicle 2 in the server 10c.

  In the management system 17, since the wireless tag 4a is reused and distributed to different vehicles each time, the information written in the memory of the wireless tag 4a is limited to the tag ID, and unique information such as vehicle information that changes each time. Is not written in the wireless tag 4a.

As shown in FIG. 1, the position information management system 1 according to the first embodiment attaches a wireless tag 4 to a vehicle 2 that is carried into a vehicle management area 13, and uses the wireless base unit 7 to store the position information of the wireless tag 4. The server 10 manages the vehicle 2 in the vehicle management area 13 (wireless tag 4). In FIG. 1, one vehicle 2 is shown from being carried into the vehicle management area 13 until being carried out from the vehicle management area 13. The vehicle 2 is provided with symbols (2a) to (2f) according to the position of the vehicle 2.

  The location information management system 1 according to the first embodiment includes a wireless tag 4 attached to a vehicle 2, a terminal 14, and a server 10.

  As illustrated in FIG. 2, the wireless tag 4 includes a CPU unit 22 (arithmetic unit), an RFID nonvolatile memory IC 29, a GPS receiving unit 24, and a wireless unit 21.

  The RFID nonvolatile memory IC 29 includes a communication unit (for example, an RFID circuit) that communicates with the outside (for example, the terminal 14) via the RFID antenna 31, and a storage unit 30 (for example, a nonvolatile memory such as an EEPROM, a Flash ROM, or a battery backup RAM). Memory). The GPS receiver 24 acquires the position information of the wireless tag 4 based on the signal from the satellite 6 received by the GPS antenna 23. The wireless unit 21 transmits an output signal from the wireless tag 4 to the wireless master device 7 via the wireless antenna 20. The CPU unit 22 causes the wireless unit 21 to transmit the position information of the wireless tag 4 received by the GPS receiving unit 24 and the identification information stored in the storage unit 30 of the RFID nonvolatile memory IC 29.

  The CPU unit 22 causes the wireless unit 21 to transmit information such as position information and identification information at predetermined intervals. As a transmission control method of the wireless unit 21 by the CPU unit 22, a method of transmitting these information only when the position of the wireless tag 4 changes in addition to a method of causing the wireless unit 21 to transmit these information at regular intervals. In addition, there is a method in which the wireless tag 4 transmits the information to the server 10 when the wireless tag 4 receives the position information request signal for requesting the information from the server 10. As a method for detecting a change in the position of the wireless tag 4, detection of a change in position and state based on position information received by the GPS receiver 24 and detection of a movement state based on a vibration sensor are used. In addition, by using the wireless tag 4 in the sleep state (the operation of the CPU unit 22 is temporarily stopped and kept in a power saving state), consumption of the battery 25 of the wireless tag 4 can be reduced.

  Since the RFID nonvolatile memory IC 29 has communication means, the wireless tag 4 can be read / written to the storage means 30 of the RFID nonvolatile memory IC 29 from the outside of the wireless tag 4 using the terminal 14. Read / write access to the RFID nonvolatile memory IC 29 can be performed from the inside by the CPU unit 22. As a result, information can be shared between the terminal 14 and the CPU unit 22 inside the wireless tag 4 through the RFID nonvolatile memory IC 29.

  The terminal 14 includes server data transmission / reception means for transmitting / receiving data to / from the server 10 and wireless tag data transmission / reception means for reading / writing data in the storage means 30 of the wireless tag 4 (not shown).

  The server data transmission / reception means of the terminal 14 includes reception means for receiving the registration information of the vehicle 2 stored in the server 10 and transmission means for transmitting to the server 10 that the management of the vehicle 2 has ended from the terminal 14. . As a communication method of the server data transmission / reception means of the terminal 14, for example, a communication method such as wireless LAN, BlueTooth (registered trademark), IrDA (registered trademark), UWB, or the like is used. The wireless tag data transmission / reception means of the terminal 14 reads / writes data in the storage means 30 via the RFID antenna 31 of the wireless tag 4. As a communication method of the wireless tag data transmitting / receiving means, for example, a communication method such as RFID (Radio Frequency IDentification) communication is used. Since RFID communication can also transmit power, the wireless tag 4 can receive signals even when the battery 25 is turned off on the wireless tag 4 side.

  As shown in FIG. 1, the server 10 is connected to a wireless master device 7 capable of wireless communication with the wireless tag 4 and a network 9 (wired network or wireless network). The server 10 transmits / receives data to / from the wireless tag 4, vehicle information registration means for registering vehicle information of the vehicle 2 carried into the vehicle management area 13, terminal data transmission / reception means for transmitting / receiving data to / from the terminal 14, and data. Wireless tag data transmitting / receiving means (not shown).

  The vehicle information of the vehicle 2 is registered in the vehicle information registration means. For example, when the vehicle management area 13 is a venue for buying and selling vehicles, the vehicle body number, vehicle type, year, color, mileage, accident history, etc. are registered as vehicle information in the vehicle information registration means of the server 10. The vehicle information is not limited to this embodiment, and necessary information is registered in the server 10 according to the management target article. The terminal data transmission / reception means includes transmission means for transmitting vehicle information registered in the vehicle information registration means of the server 10 to the terminal 14 and reception means for receiving a vehicle management processing end signal from the terminal 14. As a communication method of the terminal data transmission / reception means, for example, a communication method such as wireless LAN, BlueTooth, IrDA, UWB is used. The wireless tag data transmission / reception means of the server 10 includes reception means for receiving position information and identification information of the wireless tag 4 from the wireless master device 7 connected via the network 9. When the server 10 requests the identification information of the wireless tag 4 and receives the identification signal of the wireless tag 4, the wireless tag data transmitting / receiving unit of the server 10 requests the identification information of the wireless tag 4 from the wireless tag 4. It has a transmission means for transmitting a signal. As a communication method between the wireless master device 7 and the wireless tag 4, for example, a communication method such as wireless LAN, ZigBee (registered trademark), and power saving wireless using IEEE 802.15.4 is used.

  Next, with reference to FIG. 1, the management method of the vehicle 2 by the positional information management system 1 is demonstrated. First, the case where the vehicle information of the vehicle 2 is registered will be described with reference to the vehicles 2 (2d) and (2e).

  When the vehicle 2 (2 e) is carried into the vehicle management area 13, the vehicle information of the vehicle 2 is registered in the server 10. When this registration is performed, the card number (identification information) of the vehicle number card 5 is registered in the server 10. After registering the vehicle information in the server 10, the driver or manager 3a gives the wireless tag 4 to the vehicle 2 (2d) and posts the vehicle number card 5 on the vehicle 2 (2d). At this time, the driver or the manager 3 a transfers the card number and vehicle information of the vehicle number card 5 registered in the server 10 from the server 10 to the terminal 14, and uses the transferred card number and vehicle information using the terminal 14. Write to the RFID nonvolatile memory IC 29 in the wireless tag 4. In this way, the vehicle 2, the card number of the vehicle number card 5, the wireless tag 4, and the vehicle information registered in the server 10 are linked.

  Next, a case where the vehicle 2 is carried into the vehicle management area 13 will be described with reference to the vehicles 2 (2b) to (2d). The driver or the manager 3a posts the vehicle number card 5 on the corresponding vehicle 2, attaches the wireless tag 4 to the vehicle 2, and carries the vehicle 2 into the vehicle management area 13 from the entrance gate 12a. The carried vehicle 2 (2c) is moved to an arbitrary parking position in the vehicle management area 13 and parked.

  As shown in the vehicle 2 (2b), when the vehicle 2 is carried into the vehicle management area 13 and parked at a predetermined parking position, the GPS receiving unit 24 of the wireless tag 4 receives the positional information (vehicle 2 Is obtained from the GPS satellite 6. The CPU unit 22 acquires the card number of the vehicle number card 5 from the RFID nonvolatile memory IC 29. The acquired information is transmitted from the wireless unit 21 of the wireless tag 4 to the server 10 via the wireless master device 7. Since the RFID nonvolatile memory IC 29 is a memory, when the address of the information storage area is instructed from the server 10, the CPU 22 requests the vehicle identification information requested by the server 10 from the information stored in the RFID nonvolatile memory IC 29 (for example, Card number) can be selected and transmitted.

  Here, a method for acquiring the position information of the vehicle 2 by the server 10 will be described. When the wireless tag 4 has the GPS receiver 24, as shown in FIG. 3, the position information and the card number of the wireless tag 4 measured by the GPS satellites 6a and 6b are notified from the wireless tag 4 to the wireless base unit 7. As a result, the position information of the vehicle 2 is acquired by the server 10. In addition, the acquisition method of the positional information of the vehicle 2 by the server 10 is not limited to this form, What is necessary is just to acquire using the well-known method suitably. For example, as a well-known method for acquiring the position information of the wireless tag 4, as shown in FIG. 4, the radio wave intensity output from the wireless tag 4 detected by a plurality of wireless master units (7a, 7b, 7c) A method of detecting the position information of the wireless tag 4 based on the radio wave arrival time transmitted from the wireless tag 4 and notifying the wireless base unit 7 together with the card number, as shown in FIG. A method of notifying the wireless master device 7 of the location of the nearby wireless master device 7 as the location information of the wireless tag 4 together with the card number is known.

  Thus, since the server 10 is notified of the card number of the vehicle number card 5 and the position information of the wireless tag 4, the server 10 does not use the tag ID of the wireless tag 4 and is stored in the card number (wireless tag 4. The position information of the wireless tag 4 (that is, the vehicle 2) can be managed by the identification information).

  Furthermore, the case where the vehicle 2 is carried out from the vehicle management area 13 with reference to the vehicle 2 (2a), (2b), (2f) shown in FIG. When carrying out the vehicle 2, the driver or the manager 3b specifies the parking position of the vehicle 2 (2b) from the server 10 based on the card number described in the vehicle number card 5 of the corresponding vehicle 2. After specifying the parking position of the vehicle 2 (2 b), the vehicle 2 is picked up and the vehicle 2 (2 a) is left from the vehicle management area 13. After leaving the vehicle, the vehicle number card 5 is returned, the card number is read from the RFID nonvolatile memory 29 of the wireless tag 4 using the terminal 14, and the vehicle 2 to which the card number is attached using the terminal 14 is carried out. The server 10 is notified of the completion and the exit completion process is performed. Based on the signal from the terminal 14, the server 10 performs an unloading completion process for registering that the unloading of the vehicle 2 is completed in the vehicle information stored in the vehicle registration unit. After the carry-out completion process, the wireless tag 4 is returned to the wireless tag stock and used again for managing other vehicles.

  As described above, according to the location information management system 1 according to Embodiment 1 of the present invention, the card number and vehicle information of the vehicle number card 5 registered in the server 10 are transmitted from the server 10 to the terminal 14 using wireless communication. By transferring the information and writing the transferred information in the RFID nonvolatile memory IC 29 in the wireless tag 4 using the terminal 14, the wireless tag 4 and the card number can be linked. This simplifies the information linking management method in the server 10 and shortens the linking work time.

  Then, the server 10 does not manage the tag ID of the wireless tag 4 but can manage it using the identification information of the management target article such as a card number. As a result, the task of registering the tag ID of the wireless tag 4 in the server 10 and associating it with the card number of the vehicle number card 5 or vehicle information, as in the conventional management system, becomes unnecessary. Therefore, the operation of registering the tag ID of the wireless tag 4 in the server 10 performed by the conventional position information management system (for example, a person reads the character string of the tag ID printed on the wireless tag 4 and uses the keyboard) The work input to the server 10 and the work of reading to the server 10 by a bar code reader in the case of bar code display) are changed to the writing and reading work by the terminal 14, greatly reducing time and preventing human error.

  The management of the position information of the vehicle 2 by the server 10 is not performed by associating the tag ID of the wireless tag 4 registered in the server 10 with the card number or the management number of the vehicle number card 5 in advance. Since the card number or the management number of the number card 5 is notified, the position information of the wireless tag 4 (that is, the vehicle 2) can be managed using only the card number or the management number of the vehicle number card 5. Thus, when the position information acquired by the wireless tag 4 is notified from the wireless master device 7 to the server 10 through the network 9, the server 10 notifies the card number and the position information of the vehicle number card 5 by the server 10. It becomes possible to manage the position information by the card number without using the tag ID. As a result, tag ID management in the server 10 can be reduced, and the information association management method can be simplified.

  In addition, since this work may be performed between the time when the vehicle number card 5 is posted on the vehicle 2 when the vehicle 2 is carried in and the time when the vehicle 2 is parked at a predetermined parking position, the way of assembling the work process is flexible. Thus, the workability of the position information management system 1 is improved.

  Further, when the vehicle 2 leaves the vehicle management area 13, the terminal 14 reads the card number or the management number from the RFID nonvolatile memory IC 29 in the wireless tag 4 and notifies the server 10 of the read information from the terminal 14. The exit completion process of the vehicle 2 from the vehicle management area 13 can be performed, and the exit completion process of the vehicle 2 can be simplified.

  Since the wireless tag 4 used in the position information management system 1 according to the first embodiment of the present invention does not register the tag ID of the wireless tag 4 in the server 10 in order to manage the vehicle 2, the tag ID is displayed on the surface of the wireless tag 4. Labels (character strings, barcodes, etc.) need not be attached or stamped. In addition, the wireless tag 4 once used for managing the vehicle 2 can be rewritten to another vehicle by rewriting a new card number or vehicle information in the RFID nonvolatile memory IC 29 of the wireless tag 4 using the terminal 14. It can be used for the management of this vehicle. That is, by rewriting the information stored in the RFID nonvolatile memory IC 29 of the wireless tag 4, the wireless tag 4 can be easily used for other vehicles.

  Further, by mounting an RFID nonvolatile memory IC 29 in which a communication circuit such as an RFID circuit and a nonvolatile memory such as an EEPROM are mounted on the wireless tag 4, reading from the outside of the wireless tag 4 to the RFID nonvolatile memory IC 29 by the terminal 14. / Read access to the RFID nonvolatile memory IC 29 by the CPU unit 22 from the inside of the wireless tag 4 and information sharing via the RFID nonvolatile memory IC 29 can be performed.

  In addition to the tag ID unique to the wireless tag 4, the storage unit 30 of the wireless tag 4 stores the card number of the vehicle number card 5, vehicle information of the vehicle 2 to be managed, and the CPU unit 22 of the wireless tag 4. Using the terminal 14, various information such as setting of the operation mode of the wireless unit 21, setting of the address of the wireless unit 21 of the wireless tag 4, log collection of the operation state of each unit from the CPU unit 22, self-diagnosis result of the wireless tag 4 Can be directly written, rewritten, and read.

  As a result, the card number or management number and vehicle information of the vehicle number card 5 written in the RFID nonvolatile memory IC 29 of the wireless tag 4, the operation mode of the CPU unit 22 and the wireless unit 21, the address setting of the wireless unit 21, etc. Information, logs of operation states written from the CPU unit 22, self-diagnosis results, and the like can be read and confirmed at any time using the terminal 14.

  That is, when the driver or the administrator 3b wants to check the vehicle information of the vehicle 2 managed in the vehicle management area 13, the driver or the administrator 3b can perform the search on the spot without referring to the search by the server 10 or the vehicle information list. The vehicle information can be read and confirmed from the RFID nonvolatile memory IC 29 in the wireless tag 4 using the terminal 14.

  In addition, the terminal 14 is used to set the operation mode of the wireless unit 21 for the CPU unit 22, the address setting of the wireless unit 21, the log collection of the operation state of each unit from the CPU unit 22, the collection of self-diagnosis results Since this can be done without cable connection or switch setting, the maintenance of the location information management system 1 is improved.

(Embodiment 2)
With reference to FIG. 6, the positional information management system 8 which concerns on Embodiment 2 of this invention is demonstrated. The position information management system 8 of Embodiment 2 registers the vehicle information of the management target vehicle 2 in the server 10a, and then the vehicle number card 5a on which the server 10a has printed a barcode on which information such as a card number and vehicle information is recorded. It is the same as the location information management system 1 of the first embodiment except that information is written to the RFID nonvolatile memory IC 29 of the wireless tag 4 based on the output barcode. Therefore, in the description of the location information management system 8 of the second embodiment, the same components as those of the location information management system 1 of the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

  FIG. 6 is a diagram illustrating an overall configuration of the location information management system 8 according to the second embodiment. As shown in FIG. 6, the position information management system 8 according to the second embodiment attaches a wireless tag 4 to a vehicle 2 that is carried into the vehicle management area 13, and uses the wireless master device 7 to store the position information of the wireless tag 4.

  Before the vehicle 2 (2e) is carried into the vehicle management area 13, the vehicle information of the vehicle 2 is registered in the server 10a. When the vehicle information is registered in the server 10a, the server 10a causes the printer 15 to output the vehicle number card 5a in which the registered vehicle information is printed as a barcode. The driver or manager 3a attaches the wireless tag 4 to the vehicle 2 (2d) and posts the vehicle number card 5a on the vehicle 2 (2d).

  Next, a case where the vehicle 2 is carried into the vehicle management area 13 will be described with reference to the vehicles 2 (2b) to (2d). The driver or the manager 3a passes the entrance gate 12a, enters the vehicle 2 (2c) into the vehicle management area 13, moves the vehicle 2 to an arbitrary parking position, and parks it.

  After parking the vehicle 2, the driver or manager 3a reads the barcode printed on the vehicle number card 5a using the terminal 14a, and uses the RFID information of the wireless tag 4 to record information such as vehicle information recorded on the barcode. Write to the nonvolatile memory IC29. In this way, the vehicle 2, the card number of the vehicle number card 5a, the wireless tag 4, and the vehicle information registered in the server 10a are linked. Then, the GPS receiver 24 of the wireless tag 4 acquires the position information of the wireless tag 4 (position information of the vehicle 2), and the CPU section 22 acquires the card number of the vehicle number card 5a from the RFID nonvolatile memory IC29. The acquired information is transmitted from the wireless unit 21 of the wireless tag 4 to the server 10a via the wireless master device 7.

  Thus, since the server 10a is notified of the card number of the vehicle number card 5a and the position information of the wireless tag 4, the server 10a does not use the tag ID of the wireless tag 4, but is stored in the card number (wireless tag 4). The position information of the wireless tag 4 (that is, the vehicle 2) can be managed by the identification information).

  In addition, when carrying out the vehicle 2 from the management vehicle area 13, it carries out by the method similar to the positional information management system 1 of Embodiment 1. FIG.

  As described above, according to the location information management system 8 according to the second embodiment of the present invention, the server 10a outputs a barcode in which the card number and the vehicle information registered in the server 10a are recorded, and the output bar Based on the code, the wireless tag 4 and the vehicle number card 5a can be linked. Therefore, in addition to the effect of the location information management system 1 according to the first embodiment, the efficiency of the registration work of the vehicle 2 is further improved.

  The position information management system, position information management method, and wireless tag of the present invention are not limited to the above-described embodiments, and can be appropriately changed in design without departing from the characteristics of the present invention. The present invention also includes a position information management system, a position information management method, and a wireless tag according to the present invention.
