The user inputs the scheduled take-out time and the planned return time according to the displayed error message, selects the registration button 815 again, and completes the registration.
When there is a user who may be handed over, a group to which the user scheduled to hand over belongs is further selected.

  When the input is completed and the registration button 815 is selected, the input information is transmitted to the asset management server 3, and the asset management table 310 stored in the asset management server 3 is updated.

  The same operation can be performed in the new asset registration window 714, asset information editing window 715, user registration / group registration window 716, and user editing / group editing window 717. When registration or editing is completed, registration or editing is completed. The information thus obtained is transmitted to the asset management server 3.

In addition, when the carry-out registration terminal 7 detects unauthorized take-out or loss, it issues a warning by sounding an alarm, and sends information on illegal take-out or loss to the user's mobile phone or personal computer to notify the warning. To do.
For example, if there is tag ID information 21 that cannot be read by all the IC tag readers 10-a, 10-b, and 10-c, the carry-out registration terminal 7 notifies a warning that there is a loss.
Further, when the tag ID information 21 is read by the IC tag reader 10-c of the take-out management device 6 of a person who does not belong to the applicant or the use group, the take-out registration terminal 7 notifies a warning that there is an incorrect take-out. .
Further, when the tag ID information 21 of the managed article 1 that has not been applied for export is read by the IC tag reader 10-c of the export management device 6, the export registration terminal 7 warns that there has been an illegal export. Inform.

  Further, in response to the take-out application, the asset management server 3 is based on the current time counted by the timer 64 and the asset management table 310, even though the take-out application for the managed article 1 is registered. The management object 1 that has not been taken out by the scheduled time is detected. When the asset management server 3 detects the managed object 1 that has not been taken out by the scheduled time, the asset management server 3 cancels the take-out application information in the asset management table 310 and updates it to unregistered. Note that the managed object 1 has not been taken out by the scheduled time because the current time output by the timer 64 exceeds a predetermined time from the scheduled time for taking out included in the takeout application, and then the asset management server 3 However, it is detected by receiving the tag ID information 21 of the managed article 1 scheduled to be taken out from the storage shelf 4.

Further, the asset management server 3 detects the management target article 1 that has not been returned by the scheduled time of return based on the current time counted by the timer and the asset management table 310. When the managed object 1 that has not been returned by the scheduled time for return is detected, the asset management server 3 indicates that there is a managed object 1 that has not been returned by the scheduled return time applied to the take-out registration terminal 7. The take-out registration terminal 7 that has received the notification that there is the managed article 1 that has not been returned by the requested scheduled return time issues a warning by sounding an alarm. Further, the asset management server 3 may notify the warning by e-mail to the portable terminal or the personal computer of the applicant who applied for taking out the managed article 1.
The fact that the managed article 1 has not been returned by the time when the return is scheduled is that the current time output by the timer provided in the asset management server 3 is predetermined from the time when the return is included in the take-out application. After the elapse of time or more, the asset management server 3 detects by not receiving the tag ID information 21 of the management target article 1 scheduled to be returned from the storage shelf 4.

  Next, the operation of the asset management system 100 according to the embodiment of the present invention will be described with reference to the operation flowcharts shown in FIGS.

  The storage shelf 4 receives the tag ID information 21 transmitted from the IC tag attached to the managed article 1 stored in the storage shelf 4 (step S101), and receives the received tag ID information 21 every 100 milliseconds. To the asset management server 3 (step S102). The asset management server 3 that has received the tag ID information 21 can receive the tag ID information 21 that has been received for 500 milliseconds from the tag ID information 21 received from the storage shelf 4 (step S103). It is checked whether or not the management target article 1 having the missing tag ID information 21 has been filed (step S104).

  On the other hand, the temporary evacuation shelf 5 receives the tag ID information 21 transmitted from the IC tag attached to the managed article 1 stored in the temporary evacuation shelf 5 (step S105), and receives the received tag ID information 21. The information is transmitted to the asset management server 3 every 100 milliseconds (step S106).

  When the management object 1 having the tag ID information 21 that cannot be received from the storage shelf 4 for 500 milliseconds has been filed (step S104 is “YES”), or the asset management server 3 starts from the temporary storage shelf 5 When the tag ID information 21 that has not been received for 500 milliseconds is detected in the received tag ID information 21 (step S107), the asset management server 3 has a management target having the tag ID information 21 that cannot be received. A request is made to receive all of the receivable tag ID information 21 and transmit all of the received tag ID information 21 to the carry-out management device 6 owned by the applicant who has applied for taking out the article 1 (step S108). ). Upon receipt of this request, the carry-out management device 6 (step S109) turns on the power if the IC tag reader 10-c and the read information storage unit 61 are off, and if on, the IC tag reader 10-c. The read information storage unit 61 continues the operation (step S110), receives all the receivable tag ID information 21 ("YES" in step S111), and sends all the received tag ID information 21 to the asset management server 3. Transmit (step S112). When the tag management information 6 cannot receive the tag ID information 21 (step S111 is “NO”), the take-out management device 6 notifies the asset management server 3 that the tag ID information 21 cannot be received (step S113).

  When the tag ID information 21 is received from the take-out management device 6 (step S114), the asset management server 3 has the same tag ID as the tag ID information 21 of the managed article 1 for which the received tag ID information 21 is applied for take-out. If it is the information 21 ("YES" in step S201), the take-out management device 6 owned by the applicant is requested to monitor the managed object 1 (step S202). Upon receipt of the request, the take-out management device 6 starts monitoring the management target article 1 (step S203).

  The asset management server 3 determines that the tag ID information 21 received from the applicant's take-out management device 6 is tag ID information 21 that is different from the tag ID information 21 of the managed article 1 that has been applied for take-out (step S201). Is “NO”), it notifies the takeout registration terminal 7 that it is illegal takeout (step S204). The take-out registration terminal 7 that has received the message of illegal take-out notifies the illegal take-out warning (step S205). Further, the asset management server 3 requests the take-out management device 6 owned by the applicant to monitor the managed article 1 taken out illegally by the applicant (step S202). Upon receipt of the request, the take-out management device 6 starts monitoring the management target article 1 (step S203).

  Of the tag ID information 21 received from the storage shelf 4 by the asset management server 3, if the managed article 1 that has been unreceivable for 500 milliseconds has not been filed (step S104 is “NO”), or If the asset management server 3 receives the fact that the tag ID information 21 cannot be received from the take-out management device 6 of the applicant (step S115), the asset management server 3 receives the tag ID information 21 that can be received from all the take-out management devices 6. And request to transmit the received tag ID information 21 (step S301).

  Each take-out management device 6 (step S302) that has received the request turns on the power if the IC tag reader 10-c and the read information storage unit 61 are off, and if on, the IC tag reader 10-c. The read information storage unit 61 continues the operation. Then, each take-out management device 6 receives receivable tag ID information 21 and transmits the received tag ID information 21 to the asset management server 3 (step S303).

  The asset management server 3 has the same tag ID information 21 as the tag ID information 21 that cannot be received from the storage shelf 4 or the temporary evacuation shelf 5 for 500 milliseconds in the tag ID information 21 received from the carry-out management device 6. If this is the case ("YES" in step S304), the take-out registration terminal 7 is notified that there has been unauthorized take-out (step S305). The take-out registration terminal 7 that has received information that there has been illegal take-out notifies of an illegal take-out warning (step S306). Further, the asset management server 3 requests the take-out management device 6 of the user who has taken out illegally to monitor the management target article 1 taken out illegally (step S307). Upon receipt of the monitoring request (step S308 is “YES”), the carry-out management device 6 starts monitoring the managed article 1 (step S309).

  Further, the carry-out management device 6 receives a request for transmission of the tag ID information 21 (step S302), transmits the receivable tag ID information 21 (step S303), and then issues a request for monitoring the managed article 1 in advance. Is not received (step S308 “NO”), and if there is no monitoring target, the IC tag reader 10-c and the read information storage unit 61 are turned off (step S310).

  The asset management server 3 must have the same tag ID information 21 in the tag ID information 21 received from the carry-out management device 6 as the tag ID information 21 that can no longer be received from the storage shelf 4 or the temporary shelving shelf 5 for 500 milliseconds. If this is the case (step S304 is “NO”), the take-out registration terminal 7 is notified that the managed article 1 has been lost (step S311). Upon receipt of this notification, the take-out management terminal 7 notifies a loss warning (step S312).

  The above is the asset management flowchart in the storage shelf 4 or the temporary evacuation shelf 5. Next, a monitoring flowchart of the management target article 1 in the carry-out management device 6 will be described with reference to FIG.

  Tag ID information 21 is transmitted every 100 milliseconds from the IC tag 2 attached to the article 1 to be managed (step S401). The take-out management device 6 receives the tag ID information 21 from the IC tag 2 attached to the monitored management target article 1 (step S402), and sets the tag ID information 21 of the monitored management target article 1 to 500. When it cannot be received for milliseconds (step S403 is “YES”), the asset management server 3 is notified that the tag ID information 21 of the managed article 1 being monitored cannot be received (step S404).

When the asset management server 3 receives from the take-out management device 6 that it cannot receive the tag ID information 21 of the managed article 1 that is being monitored (step S405), the asset management server 3 refers to the asset management table 310 and receives the tag ID that can no longer be received. It is confirmed whether the information 21 is received from the storage shelf 4 or the temporary evacuation shelf 5 (step S406). If the tag ID information 21 that cannot be received by the take-out management device 6 has been received from the storage shelf 4 or the temporary evacuation shelf 5 (“YES” in step S406), the asset management server 3 selects the corresponding managed object 1 The monitoring management device 6 that has been monitored is requested to stop monitoring the corresponding managed article 1 (step S407). The take-out management device 6 that has received the request ends the monitoring of the management target article 1 requested to stop monitoring (step S408).
Further, the monitoring stop is received, and the monitoring of the management target article 1 is finished (step S408). If there is another management target article 1 that is being monitored, the carry-out management apparatus 6 (step S409 is “YES”). Monitoring is continued (step S410), and if there is no management target article 1 being monitored (step S409 is “NO”), the power of the IC tag reader 10-c and the read information storage unit 61 is turned off, and the monitoring ends. (Step S411)

  When the tag ID information 21 that can no longer be received by the take-out management device 6 has not been received from either the storage shelf 4 or the temporary evacuation shelf 5 (step S406 is “NO”), the asset management server 3 Is requested to send all received tag ID information 21 to the asset management server 3 (step S412).

  When each asset management server 3 is requested to transmit the tag ID information 21 (step S413), each take-out management device 6 turns on the power if the IC tag reader 10-c and the read information unit 61 are off. . If the power supply of the IC tag reader 10-c and the read information unit 61 is on, these power supplies are kept on as they are. Each carry-out management device 6 receives all the receivable tag ID information 21 and transmits the received tag ID information 21 to the asset management server 3 (step S414).

  When the asset management server 3 receives the tag ID information 21 from the take-out management device 6, the received tag ID information 21 includes the same tag ID information 21 as the tag ID information 21 of the taken-out management target article 1. Whether or not (step S415).

  If there is the same tag ID information 21 as the tag ID information 21 of the taken-out management target article 1 (“YES” in step S415), the asset management server 3 sends the corresponding tag ID information 21 to the takeout management device. It is checked whether or not 6 is a take-out management device 6 possessed by a user belonging to the delivery group registered at the time of take-out application (step S416).

  When the carry-out management device 6 that has transmitted the corresponding tag ID information 21 is the carry-out management device 6 possessed by a user belonging to the delivery group registered at the time of the take-out application (step S416 is “YES”). The asset management server 3 requests the take-out management apparatus 6 that can receive the relevant tag ID information 21 to monitor the managed article 1 (step S417), and the take-out management that can no longer receive the relevant tag ID information 21. The apparatus 6 is requested to stop monitoring the management target article 1 (step S418).

The take-out management device 6 that has received the request for monitoring the managed object 1 (“YES” in step S419) starts monitoring the managed object 1 (step S420), and receives the monitored request for the managed object 1 If not (step S419 “NO”), the carry-out management device 6 turns off the power of the IC tag reader 10-c and the read information storage unit 61 after a predetermined time if there is no monitoring target (step S421).
In addition, when the monitoring stop of the management target article 1 is received and the monitoring of the management target object is finished (step S408), the carry-out management apparatus 6 has another management target article 1 being monitored (step S409). Monitoring is continued (step S410), and if there is no managed article 1 being monitored (step S409 is “NO”), the IC tag reader 10-c and the read information storage unit 61 are turned off. Monitoring is terminated (step S411).

  However, when the requested tag ID information 21 is received from the carry-out management device 6 possessed by a user who does not belong to the delivery group (step S416 is “NO”), the asset management server 3 sends it to the carry-out registration terminal 7. A notification that there has been unauthorized take-out is sent (step S422). The take-out registration terminal 7 that has been notified that there has been an unauthorized take-out notifies an illegal take-out warning (step S423).

  Further, the asset management server 3 requests the take-out management apparatus 6 that can receive the corresponding tag ID information 21 to monitor the managed article 1 (step S417), and the asset management server 3 can no longer receive the corresponding tag ID information 21. The output management device 6 is requested to stop monitoring the managed article 1 (step S418).

  The take-out management device 6 that has received the request for monitoring the managed object 1 (“YES” in step S419) starts monitoring the managed object 1 (step S420), and receives the monitored request for the managed object 1 If not (step S419 “NO”), the carry-out management device 6 turns off the power of the IC tag reader 10-c and the read information storage unit 61 after a predetermined time if there is no monitoring target, and ends the monitoring (step S421). .

  Among the tag ID information 21 received by the asset management server 3 from all the carry-out management devices 6, there is no tag ID information 21 that is the same as the tag ID information 21 that cannot be received during the monitoring by the carry-out management device 6 ( If “NO” in step S415), the take-out registration terminal 7 is notified that the managed item 1 has been lost (step S424). Upon receipt of the notification, the take-out registration terminal 7 notifies a loss warning (step S425).

In addition, the asset management server 3 requests the take-out management device 6 that cannot receive the tag ID information 21 to stop monitoring the lost managed article 1 (step S416). Upon receipt of the request, the take-out management device 6 ends the monitoring of the lost managed article 1 (step S408).
In addition, when the monitoring stop of the management target article 1 is received and the monitoring of the management target article 1 is finished (step S408), the carry-out management apparatus 6 has another management target article 1 being monitored (step S409). Is “YES”), monitoring is continued (step S410), and if there is no article 1 to be monitored being monitored (“NO” at step S409), the IC tag reader 10-c and the read information storage unit 61 are turned off. Monitoring is terminated (step S411).
