  FIG. 2 is a diagram showing an example of articles managed by the article management system shown in FIG.

  As an article managed by the article management system shown in FIG. 1, for example, there is a document file 100 as shown in FIG. The document file 100 is affixed with a non-contact type IC label 101 which is an RF-ID medium in which a document ID capable of identifying the document file 100 is written, and the document file 100 is placed on the shelf 3. In the state, the document ID written on the non-contact type IC label 101 is read through the antennas 4-1 to 4-4. The non-contact type IC label 101 may be attached to the inner surface of the document file 100, and the non-contact type IC label 101 is not attached to the document file 100 as an RF-ID medium. An RF-ID medium such as a contact IC tag may be incorporated in the document file 100 itself, or an insertion part may be provided in the document file 100 by a film case or the like and stored therein. The thickness of the document file 100 varies depending on the amount of documents filed inside.

  Hereinafter, as an article management method in the article management system configured as described above, a case where the storage status of the document file 100 shown in FIG. 2 in the cabinet 1 is managed will be described as an example.

  First, opening / closing control of the electric lock 5 will be described.

  FIG. 3 is a flowchart for explaining opening / closing control of the electric lock 5 in the article management system shown in FIG.

  A user who wants to take out the document file 100 stored in the cabinet 1 or return the document file 100 taken out of the cabinet 1 to the cabinet 1 puts the ID card on which the user ID is written into the card reader 6. Then, the user ID is read from the ID card by the card reader 6 (step S1). The card reader 6 is provided on the front surface of the cabinet 1, and the user puts the ID card in the area where the card reader 6 is provided on the front surface of the cabinet 1.

  The user ID read by the card reader 6 is notified to the opening / closing authority management unit 21.

  In the open / close authority management unit 21, the user ID notified from the card reader 6 is collated with the user ID stored in the memory 22, so that the user ID notified from the card reader 6 identifies the user ID. It is determined whether or not the user to be authorized has the authority to unlock the electric lock 5 (step S2). Here, the authority to unlock the electric lock 5 is set in the electric lock setting unit 11 of the management computer 10, and the user ID of the user who has the authority to unlock the electric lock 5 is stored in the memory 22. Since it is stored, the open / close authority management unit 21 is notified from the card reader 6 by collating the user ID notified from the card reader 6 with the user ID stored in the memory 22. It can be determined whether or not the user identified by the user ID has the authority to unlock the electric lock 5.

  If the user identified by the user ID notified from the card reader 6 does not have the authority to unlock the electric lock 5, an error is output by an LED or the like (not shown) provided in the cabinet 1. If the user identified by the user ID notified from the card reader 6 has the authority to unlock the electric lock 5, the control by the opening / closing control unit 23 is performed. The electric lock 5 is unlocked and the door 2 can be freely opened and closed (step S4). Thus, the electric lock controller 20 detects that the door 2 has been opened.

  In the electric lock controller 20, when the electric lock 5 is unlocked, the fact that the electric lock 5 has been unlocked and the user ID read by the card reader 6 and the electric lock 5 are unlocked. The information indicating the time is notified from the open / close state notifying unit 24 to the management personal computer 10 (step S5).

  In the management personal computer 10, the information notified from the open / close state notification unit 24 is acquired by the open / close state acquisition unit 12 (step S6). Thereby, in the management personal computer 10, it is managed when and by which user the electric lock 5 of the cabinet 1 is unlocked.

  Thereafter, when the door 2 is closed (step S7), the electric lock 5 is locked, and the fact that the electric lock 5 is locked is notified to the management personal computer 10 from the open / close state notification unit 24 together with information indicating the time ( Step S8). As a result, the electric lock controller 20 detects that the door 2 is closed.

  In the management personal computer 10, the information notified from the open / close state notification unit 24 is acquired by the open / close state acquisition unit 12 (step S9). Thereby, in the management personal computer 10, when the electric lock 5 of the cabinet 1 was locked is managed.

  Next, management of taking out the document file 100 from the cabinet 1 and processing for changing the storage section of the document file 100 will be described.

  FIG. 4 is a flowchart for explaining take-out management of the document file 100 from the cabinet 1 and change processing of the storage section of the document file 100 in the article management system shown in FIG.

  In the RFID controller 30, the antenna switching unit 31 switches the supply of current to the antennas 4-1 to 4-4 incorporated in the four shelves 3, and is thus placed on the shelf 3. The antenna for reading the document ID written on the non-contact IC label 101 attached to the document file 100 stored in the cabinet 1 is switched (step S11).

  In the information reading unit 32 of the RFID controller 30, the document ID is read via the antenna supplied with current by the antenna switching unit 31 among the antennas 4-1 to 4-4 built in the four shelves 3. Performed (step S12). Then, the read document ID is sent to the information reading unit 32 together with an antenna ID that can identify the antenna from which the document ID is read.

  In the information reading unit 32, the document ID read via the antenna is stored in the memory 33 (step S13).

  FIG. 5 is a diagram illustrating an example of information stored in the memory 33 illustrated in FIG.

  As shown in FIG. 5, the memory 33 shown in FIG. 1 reads each of the antennas 4-1 to 4-4 built in the four shelves 3 through the antennas 4-1 to 4-4. The issued document ID is stored in association with the antenna ID that can identify the antennas 4-1 to 4-4. The document ID is stored every time current is supplied to the antennas 4-1 to 4-4 by the antenna switching unit 31, but as shown in FIG. The result of reading the information twice is stored. In the example shown in FIG. 5, the document ID “A103” newly added to the antenna identified by the antenna ID “CCCC” is newly stored in the memory 33 this time compared to the one previously stored in the memory 33. Has been read.

  In the information comparison unit 34 of the RFID controller 30, the document IDs read through the antennas 4-1 to 4-4 built in the four shelves 3 and stored in the memory 33 are built in the four shelves 3. For each of the antennas 4-1 to 4-4, the document ID previously stored in the memory 33 and the document ID stored in the current memory 33 are compared (step S14).

  If there is a document ID that does not match between the document ID previously stored in the memory 33 and the document ID stored in the memory 33 this time (step S15), the document ID is the antenna ID from which the document ID was read. Along with information indicating the antenna ID, information indicating the reading time of the current document ID, and information indicating whether the document ID is increased or decreased with respect to the previous reading result, the information transmitting unit 35 sends the management personal computer 10. (Step S16). In the case of the example illustrated in FIG. 5, the document ID “A103”, the antenna ID “CCCC”, information indicating the reading time of the current document ID, and information indicating that the document ID has increased are the information transmission unit 35. To the management personal computer 10.

  The document ID transmitted from the information transmitting unit 35 to the management personal computer 10 is received by the read information acquisition unit 13 of the management personal computer 10 (step S17).

  Then, when the document ID stored in the memory 33 this time has increased with respect to the document ID previously stored in the memory 33 (step S18), first, the document information database 8a is referred to in the situation determination unit 14. The storage area of the document file 100 identified by the increased document ID is confirmed (step S19), and the document file 100 is previously stored in the storage section divided by the readable range of the antennas 4-1 to 4-4. It is determined whether or not it has been returned to the determined storage compartment (step S20). In the case of the example shown in FIG. 5, the storage section of the document ID “A103” is confirmed.

  FIG. 6 is a diagram showing information indicating the storage area of the document file 100 registered in the document information database 8a shown in FIG.

  The document file 100 stored in the cabinet 1 has a predetermined storage section in the cabinet 1, and the document ID assigned to the document file 100 is stored in the document information database 8a as shown in FIG. Are registered in association with the antenna ID of the antenna whose readable range is the storage section of the document file 100.

  For this reason, the situation determination unit 14 increases the document ID by checking whether or not the document ID increased in the document information database 8a is associated with the antenna ID from which the document ID is read. It can be determined whether or not the document file 100 identified by the document ID has been returned to the predetermined storage compartment.

  When it is determined that the document file 100 identified by the increased document ID has not been returned to the predetermined storage compartment, the user ID acquired together with the open / closed state of the door 2 by the open / closed state acquisition unit 12 is obtained. Confirmed (step S21). The confirmation of the user ID includes information indicating the reading time of the document ID transmitted from the RFID controller 30 to the management personal computer 10 together with the document ID, and the use acquired immediately before that time by the open / close state acquisition unit 12. This is performed using the person ID. In the example shown in FIG. 5, the document file 100 identified by the document ID “A103” should be stored in the storage section that is the readable range of the antenna identified by the antenna ID “BBBB”. On the other hand, the document file 100 identified by the document ID “A103” is not returned to the predetermined storage section because it is stored in the storage section that is the readable range of the antenna identified by the antenna ID “CCCC”. It will be judged.

  Then, the status determination unit 14 refers to the change authority database 8c, and the user ID acquired together with the open / close state of the door 2 by the open / close state acquisition unit 12 has the authority to change the storage compartment of the document file 100. Whether the user ID is the user's user ID (step S22).

  When the user ID acquired by the open / close state acquisition unit 12 together with the open / closed state of the door 2 is the user ID of an administrator who has the authority to change the storage compartment of the document file 100, that is, in the card reading period 6. When the right to change the storage section of the document file 100 is accepted, the status determination unit 14 confirms the open / closed state of the door 2 acquired by the open / closed state acquiring unit 12 (step S23). The confirmation of the open / closed state of the door 2 is acquired by the open / closed state acquisition unit 12 immediately before the time and the information indicating the reading time of the document ID transmitted from the RFID controller 30 to the management personal computer 10 together with the document ID. Open / closed state.

  When the document ID reading time has passed and the door 2 is closed (step S24), the status determination unit 14 updates the information indicating the storage section of the document file 100 registered in the document information database 8a (step S25). ).

  For example, as shown in FIG. 6A, the readable range of the antenna identified by the antenna ID “BBBB” is identified by the document IDs “A101”, “A102”, “A103”, “A104”. The document file 100 is stored in the readable range of the antenna identified by the antenna ID “CCCC”, and the document file 100 identified by the document ID “A201” and “A202” is stored. Storage compartments are determined. On the other hand, as shown in FIG. 5, the document file 100 identified by the document ID “A103” taken out from the cabinet 1 is changed by an administrator who has the authority to change the storage section of the document file 100. When returned to the storage section that is the readable range of the antenna identified by the antenna ID “CCCC”, the readable range of the antenna identified by the antenna ID “BBBB” is as shown in FIG. The document files 100 identified by the document IDs “A101”, “A102”, “A104” are stored, and the readable range of the antenna identified by the antenna ID “CCCC” includes the document IDs “A201”, “A202”. ”,“ A103 ”as a document file 100 to be stored 00 of the storage compartment is updated.

  Thereafter, in the storage status management unit 15, the document file 100 identified by the document ID received by the read information acquisition unit 13 is acquired by the open / close state acquisition unit 12 at the time when the document ID is read. It is recognized by the user identified by the user ID that the user has returned to the storage section that is the readable range of the antenna identified by the antenna ID of the cabinet 1, and the document file 100 registered in the storage information database 8b The storage status is updated and managed with the updated contents (step S26).

  If it is determined that the document file 100 identified by the increased document ID has been returned to the predetermined storage area, the user ID acquired by the open / close state acquisition unit 12 is confirmed (step S1). S27), the document file 100 identified by the document ID received by the read information acquisition unit 13 is identified by the user ID acquired by the open / close state acquisition unit 12 at the time when the document ID is read. That the user has returned to the storage section that is the readable range of the antenna identified by the antenna ID of the cabinet 1, and the storage status of the document file 100 registered in the storage information database 8b is updated. .

  In addition, when the document ID stored in the memory 33 this time decreases with respect to the document ID previously stored in the memory 33, it is determined that the document file 100 identified by the document ID has been taken out of the cabinet 1. Then, the status determination unit 14 refers to the document information database 8a and confirms the user authority (step S28).

  In the document information database 8a, an authority level is assigned to the user ID, and a security level is assigned to the document ID of the document file 100, and these authority levels and the security levels are associated with each other. Therefore, it is managed which document file 100 among the document files 100 stored in the cabinet 1 can be taken out by the user identified by the user ID.

  In the situation determination unit 14, the document information database 8a is referred to, and the confidential level of the document ID that can no longer be read and the authority level of the user who unlocked the electric lock 5 immediately before the time when the document ID can no longer be read. And the user who unlocked the electric lock 5 has the authority to take out the document file 100 whose document ID can no longer be read from the cabinet 1 (step S29), the storage status management unit 15 stores the storage information. The storage status of the document file 100 registered in the database 8b is updated to a state where the document file 100 whose document ID cannot be read is taken out of the cabinet 1.

  In the determination of step S22, the user ID acquired together with the open / closed state of the door 2 by the open / closed state acquisition unit 12 is not the user ID of the administrator who has the authority to change the storage section of the document file 100. If the user who unlocked the electric lock 5 is not authorized to take out the document file 100 whose document ID can no longer be read from the cabinet 1, an instruction to output an alarm is output from the alarm instruction unit 16, An alarm is output from the alarm device 7 of the cabinet 1 (step S30).

  As described above, in this embodiment, when an administrator who has a change authority to change the storage section in which the document file 100 is stored changes the storage section of the document file 100, the manager's ID card is stored in the card reader 6. The change authority is accepted by hesitating, and the storage section of the document file 100 can be changed simply by storing the document file 100 in the storage section after the change and closing the door 2.

  In this embodiment, the document ID read via the antenna is stored in the memory 33 in the RFID controller 30, and only the document ID that does not match the previously stored one is transmitted to the management personal computer 10. However, the document ID read through the antenna is all transmitted to the management computer 10 together with the antenna ID of the antenna from which the document ID is read and information indicating the reading time. A configuration may also be adopted in which the results of reading through the same antenna are compared.

  In addition, the number of cabinets 1 and shelves 3 in this embodiment and the number of antennas 4-1 to 4-4 built in one shelf are not limited to these and can be set as appropriate. When a plurality of cabinets 1 are managed by one management personal computer 10, the electric lock controller 20 and the RFID controller 30 for each cabinet 1 are branched by a hub or the like. Further, the movement of the document file 100 between the plurality of cabinets 1 is performed in the same manner as described above.
