It is a block block diagram of the semi-active tag in an Example. It is a block block diagram of the semi-active tag system in an Example. It is a process flowchart of the semi-active tag system in an Example.

  Embodiments of the present invention will be described below with reference to the drawings.

  In this embodiment, a semi-active tag method will be described as an example of a system using a wireless tag.

  FIG. 1 is a basic block configuration diagram of a semi-active tag in the present embodiment. In FIG. 1, a semi-active tag 101 is activated when a processing unit 202 receives an induction power (trigger signal) from a magnetic field by a receiving antenna 201 and activates the user individual input from a user I / F (interface) 203. A function of transmitting information to an external receiving device by the transmitting antenna 204 is mounted together with information that can be identified and a unique tag ID built in a storage unit that is not described. Reference numeral 205 denotes a battery which supplies energy for the semi-active tag 101 to perform processing.

  Here, the user I / F 203 is a personal identification number input unit, and the user inputs a personal identification number. Specifically, the user I / F 203 may be any device capable of inputting a number, and may be a mechanical switch such as a numeric keypad, a toggle switch, a dip switch, or a rotary switch, for example.

  FIG. 2 is a block diagram of the semi-active tag system in the present embodiment. In FIG. 2, reference numeral 300 denotes a trigger transmission device that transmits a trigger signal for starting the semi-active tag 101. Device. In the following, the operation of the case where the semi-active tag system is, for example, an entrance / exit management system in FIG. 2 will be described. FIG. 3 shows a process flowchart of the semi-active tag system in the present embodiment, which will be described together.

  2 and 3, a unique tag ID is assigned to the semi-active tag 101, and the semi-active tag 101 is carried and used by the user (entrance / exit person). For example, when the user intends to enter a predetermined room, the semi-active tag 101 is transmitted by the trigger device 301 of the trigger transmission device 300 and the trigger magnetic field generating coil 302 installed near the entrance of the room. The received trigger signal is received and activated, and a trigger ID, which is a unique signal from the trigger transmission device 300, is acquired and received (step 31).

  Then, the semi-active tag 101 takes in the personal identification number input from the user I / F 203 (step 32), associates the unique tag ID with the personal identification number input from the user I / F 203, and manages it as tag information. (Step 33). The semi-active tag 101 may transmit the received trigger ID, the unique tag ID, and the personal identification number as tag information to the management apparatus 400 in association with each other.

  The management device 400 receives the received tag information from the tag information receiving antenna 402 and the tag information receiving device 401, and the system processing device 403 stores the unique tag ID of the semiactive tag 101 stored in advance and the semiactive tag. The personal identification number unique to the user who uses the tag 101 is checked against the received tag information to check whether the user using the semi-active tag 101 is a registered user (step 34). As a result, if it is confirmed that the user using the semi-active tag 101 is a registered user, the room door is unlocked, and entrance / exit management such as entry / exit records of the person entering / exiting is performed (steps). 35). If it is determined that the user is not a registered user, the lock is not released and a message indicating that the user is not approved is displayed (step 36).

  Note that the code number fetching in step 32 is triggered by the fact that the trigger signal has been received, but if the authentication in step 34 fails, a reset button or the like is provided and the code number is fetched again. Also good.

  In step 33, when the tag ID and the password are transmitted to the management apparatus 400, they may be encrypted and transmitted. Thereby, the security of the user-specific personal identification number can be strengthened.

  In addition, if it is troublesome to enter the PIN from the user I / F 203 at the timing when the trigger signal is received, the PIN is input in advance before receiving the trigger signal, and processing is performed at the timing when the trigger signal is received. The unit 202 may automatically capture. Alternatively, the timing at which the trigger signal is received may be displayed with an LED or the like, and the password may be captured when the user presses the password number import button while viewing the display. In the case of inputting a personal identification number in advance, it is desirable that the personal identification number is reset after the personal identification number is taken in to prevent the personal identification number from being stored and used many times.

  The user I / F 203 may be a device that can identify an individual such as fingerprint authentication or vein authentication instead of inputting a personal identification number. In that case, the user performs an operation of holding a finger or vein over the user I / F 203.

  Further, the wireless tag may be an active tag method or a passive tag method instead of the semi-active tag method.

  As described above, the present embodiment is a wireless tag that transmits information to a receiving device of a management device installed in a predetermined area, and includes a storage unit that stores a unique tag ID and information that can identify an individual user. It is configured to include a processing unit that takes in user I / F to be input and information that can be used to identify the individual user input from the user I / F and transmits information combined with the tag ID.

  In addition, the security system uses a wireless tag that transmits information to a management device installed in a predetermined area and a receiving device of the management device, and the wireless tag includes a storage unit that stores a unique tag ID, a personal user, A user I / F that inputs identifiable information and a processing unit that takes in information that can identify an individual user input from the user I / F and transmits information combined with a tag ID, and the management device stores in advance It is configured to collate the tag ID of the wireless tag and the identification information unique to the user who uses the wireless tag with the tag ID received from the wireless tag via the receiving device and information that can identify the individual user.

  Accordingly, it is possible to provide a security system that can have a high security level of a security system using a wireless tag.
