  Next, each functional block of base unit 10 will be described.

  The position detection unit 11 detects the position of the own device. For example, the position detection unit 11 may acquire position information of its own device using a GPS receiver. Moreover, the position detection part 11 may acquire the positional information on an own apparatus using the autonomous navigation unit containing a gyro sensor, an acceleration sensor, etc. Further, the position detection unit 11 may acquire the position information of its own device based on the position information of the wireless base station that is the nearest communication destination by the wireless communication module 2007. Further, the position detection unit 11 may detect the position information of the own device by combining information based on the GPS receiver, the autonomous navigation unit, and the radio base station.

  The object information storage unit 12 stores identification information of the wireless tag 30 attached to the object. The object information storage unit 12 may store information such as the name of the object to which the wireless tag 30 is attached in association with the identification information of the wireless tag 30.

  An example of information stored in the object information storage unit 12 is shown in FIG. FIG. 4 shows that, for example, a wireless tag 30 with a tag ID (identification information) “001” is attached to an object named “wallet”.

  The identification information receiving unit 13 receives the identification information from the wireless tag 30. If the wireless tag 30 is composed of an active tag, the identification information receiving unit 13 receives identification information transmitted from the wireless tag 30 at a predetermined interval. Alternatively, if the wireless tag 30 is configured by a passive tag, the identification information receiving unit 13 receives the identification information by transmitting radio waves of a predetermined frequency to the wireless tag 30 at predetermined intervals.

  The alarm detection unit 14 detects a wireless tag 30 whose reception status by the identification information receiving unit 13 satisfies a predetermined alarm condition among the wireless tags 30 whose identification information is stored in the object information storage unit 12. The predetermined alarm condition may be, for example, that the identification information cannot be received. Alternatively, the predetermined alarm condition may be that a value representing the strength of the radio wave received from the wireless tag 30 is equal to or less than a threshold value. In this case, the alarm detection unit 14 may determine whether or not the alarm condition is satisfied by acquiring a value representing the strength of the received radio wave from each wireless tag 30 from the identification information receiving unit 13.

  The alarm information transmission unit 15 transmits alarm information regarding the wireless tag 30 detected by the alarm detection unit 14 to the alarm receiver 20. The alarm information includes identification information of the wireless tag 30 that satisfies the alarm condition, and position information (hereinafter also referred to as an alarm detection position) indicating the position of the own device detected by the position detection unit 11. In addition, the alarm information transmission unit 15 includes the date and time when the alarm condition is determined to satisfy the alarm condition (hereinafter also referred to as the alarm detection date and time), the identification information of the base unit 10, and the target to which the corresponding wireless tag 30 is attached. You may include the name of the thing.

  An example of alarm information transmitted by the alarm information transmitter 15 is shown in FIG. The alarm information shown in FIG. 5 indicates that the alarm detection position of the wireless tag 30 with the tag ID “001” is “latitude 35.646067, longitude 139.747589”. In this alarm information, the alarm detection date and time of the wireless tag 30 with the tag ID “001” is “9:00 on September 1, 2011”, and the name of the object to which the wireless tag 30 is attached is “wallet”. This indicates that the identification information of the parent device 10 that is the transmission source of this alarm information is “A1”.

  Next, each functional block of the alarm receiver 20 will be described.

  The alarm information receiving unit 21 receives alarm information transmitted from the parent device 10.

  The alarm information storage unit 22 stores the received alarm information.

  The alarm detection position notifying unit 23 notifies the position information included in the alarm information of the alarm information stored in the alarm information storage unit 22. For example, the alarm detection position notification unit 23 may display a map image on which the image indicating the position information included in the alarm information is superimposed on the liquid crystal display 2003. The alarm detection position notification unit 23 may display such a map image indicating the alarm detection position by accessing a web application service that displays a map image including the specified position on an arbitrary scale via the network. Good.

  The identification information receiving unit 24 receives the identification information from the wireless tag 30 indicated by the identification information included in the alarm information stored in the alarm information storage unit 22.

  The discovery detection unit 25 controls the alarm detection position notification unit 23 so as to end notification regarding alarm information satisfying a predetermined discovery condition among the alarm information stored in the alarm information storage unit 22. The predetermined discovery condition may be, for example, that identification information included in the alarm information is received by the identification information receiving unit 24.

  The operation of the information processing system 1 configured as described above will be described with reference to FIG. It is assumed that the identification information of the wireless tag 30 attached to the object is already stored in the object information storage unit 12 of the parent device 10. In FIG. 6, the left diagram represents the operation of the parent device 10, the right diagram represents the operation of the alarm receiver 20, and the dashed arrows connecting the left and right represent the data flow between the devices.

First, the alarm detection part 14 of the main | base station 10 acquires the reception condition by the identification information receiving part 13 about each identification information stored in the target object information storage part 12 (step S1). For example, the alarm detection unit 14 may acquire information indicating whether or not the identification information is received by the identification information receiving unit 13 from the identification information receiving unit 13 as the reception status. Next, the alarm detection unit 14 determines whether the reception status of the identification information satisfies a predetermined alarm condition (step S2). For example, the alarm detection unit 14 may determine that the alarm condition is satisfied when the identification information receiving unit 13 has not received the identification information.

  Here, when it is determined that the reception status of the identification information does not satisfy the predetermined alarm condition, the base unit 10 ends the processing for this identification information, and the next identification stored in the object information storage unit 12 The process for information is repeated from step S1. In addition, when the processing for all the identification information stored in the object information storage unit 12 is completed, the master unit 10 again performs the process from step S1 on each identification information stored in the object information storage unit 12. Repeat the process.

  On the other hand, if it is determined in step S2 that the reception status of the identification information satisfies a predetermined alarm condition, the alarm information transmission unit 15 acquires position information detected by the position detection unit 11 (step S3).

  Next, the alarm information transmitting unit 15 transmits alarm information including the identification information determined to satisfy the alarm condition in step S2 and the position information acquired in step S3 to the alarm receiver 20 (step S4).

  Next, the alarm information receiving unit 21 of the alarm receiver 20 receives the alarm information from the parent device 10 (step S5). At this time, the alarm information receiving unit 21 stores the received alarm information in the alarm information storage unit 22.

  Next, the alarm detection position notifying unit 23 notifies the position information included in the received alarm information (step S6). For example, as described above, the alarm detection position notification unit 23 may display a map image indicating the alarm detection position on the liquid crystal display 2003.

  Here, the alarm receiver 20 is carried by the user of the alarm receiver 20. If the user who confirmed the notification of the alarm detection position moves to the vicinity of the alarm detection position, the alarm receiver 20 is in a position where the radio wave from the wireless tag 30 having the identification information included in the alarm information can be received. There is a case.

  Therefore, next, the discovery detection unit 25 acquires the reception status of the identification information included in the alarm information (step S7). For example, the discovery detecting unit 25 may acquire information indicating whether or not the identification information is received by the identification information receiving unit 24 as the reception status.

  Next, the discovery detection unit 25 determines whether the reception status of the identification information satisfies a predetermined discovery condition (step S8). For example, the discovery detection unit 25 may determine that the discovery condition is satisfied when the identification information is received by the identification information receiving unit 24.

  Here, when it is determined that the reception status of the identification information included in the alarm information does not satisfy the discovery condition, the alarm receiver 20 continues the operation from step S7.

  On the other hand, when it is determined that the reception status of the identification information included in the alarm information satisfies the discovery information, the discovery detection unit 25 ends the notification by the alarm detection position notification unit 23 (step S9). For example, the discovery detection unit 25 ends the display of the map image on which the image indicating the alarm detection position is superimposed. Accordingly, the discovery detection unit 25 may delete the corresponding alarm information stored in the alarm information storage unit 22. When the alarm information receiving unit 21 receives alarm information including other identification information in parallel and the alarm information storage unit 22 stores a plurality of pieces of alarm information, the discovery detection unit 25 For the remaining alarm information stored in the alarm information storage unit 22, the processing from step S6 is repeated.

  Thus, the information processing system 1 ends the operation.

  Next, effects of the first exemplary embodiment of the present invention will be described.

  The information processing system as the first embodiment of the present invention can more reliably prevent the loss of belongings.

  The reason is that when the alarm detection unit of the master unit detects that the reception status of the identification information from the wireless tag attached to the object satisfies the alarm condition, the alarm information transmission unit This is because alarm information including tag identification information and parent machine position information is transmitted to the alarm receiver. Then, the alarm detection position notifying unit of the alarm receiver notifies the position information included in the received alarm information, and the identification information receiving unit communicates with the wireless tag indicated by the identification information included in the received alarm information. This is because the discovery detecting unit terminates the notification when the reception status of the identification information satisfies the discovery condition. Here, when the alarm receiver receives the alarm information, the alarm receiver may be located at a position far from the wireless tag having the identification information included in the alarm information so that the identification information cannot be received. At this time, it is assumed that the user of the alarm receiver moves to the vicinity of the alarm detection position by confirming the notification by the alarm detection position notification unit. In this case, the alarm receiver carried by the user is located at a distance where the identification information can be received from the wireless tag having the identification information included in the alarm information. As described above, the information processing system according to the present embodiment is capable of identifying from the wireless tag attached to the belongings that are not carried, even if the user of the parent device is unaware of the carrying of the belongings. The alarm receiver user is notified until the information reception condition satisfies the discovery condition. As a result, the information processing system according to the present embodiment can assist the user of the alarm receiver in finding belongings that are not carried by the user of the parent device. As a result, the information processing system as the present embodiment can more reliably prevent the loss of the belongings of the user of the parent device.

In FIG. 13, the left diagram represents the operation of the server device 60, the right diagram represents the operation of the alarm receiver 50, and the dashed arrows connecting the left and right represent the data flow between the devices.

  In FIG. 12, first, the alarm detection unit 44 of the parent device 40 acquires information indicating the alarm condition and the condition requiring attention via the input device 1004 (step S11).

  Next, the alarm detection unit 44 acquires the reception status of the identification information reception unit 13 for each identification information stored in the object information storage unit 12 (step S12).

  Next, the alarm detection unit 44 determines whether or not the reception status of the identification information satisfies the caution condition acquired in step S11 (step S13). For example, if the caution condition is that the strength of the received radio wave is less than or equal to the threshold, the alarm detection unit 44 determines whether or not the strength of the received radio wave including the identification information is less than or equal to the threshold. Also good.

  Here, when the reception status of the identification information does not satisfy the caution condition, the base unit 40 ends the process for the identification information and performs the process for the next identification information stored in the object information storage unit 12. Repeat from S12.

  On the other hand, when the reception status of the identification information satisfies a caution condition, the notification unit 46 notifies the information indicating the alert to the object to which the wireless tag 30 having the identification information is attached (step S14). For example, as described above, the notification unit 46 may display the name of the target object on the liquid crystal display 1003 and output a warning sound from the speaker 1005.

  Next, the alarm detection unit 44 determines again whether or not the reception status of the identification information satisfies the caution required acquired in step S11 (step S15).

  Here, if the reception status of the identification information does not satisfy the caution condition, the notification unit 46 ends the notification started in step S14 (step S16). And the main | base station 40 complete | finishes the process with respect to this identification information, and repeats the process with respect to the following identification information stored in the target object information storage part 12 from step S12.

  On the other hand, when the reception status of the identification information still satisfies the caution condition, the alarm detection unit 44 determines whether or not the reception status of the identification information satisfies the alarm condition acquired in step S11 (step S11). S17). For example, when it is set as the alarm condition that the identification information is not received, the alarm detection unit 44 determines that the alarm condition is satisfied if the identification information is not received by the identification information receiving unit 13. To do.

  Here, when it is determined that the reception status of the identification information does not satisfy the alarm condition, the alarm detection unit 44 repeats the processing from step S15.

  On the other hand, when it is determined that the reception status of the identification information satisfies the alarm condition, the alarm information transmission unit 45 acquires the position information detected by the position detection unit 11 (step S18).

  Next, the alarm information transmitting unit 45 transmits alarm information including the identification information determined to satisfy the alarm condition in step S17 and the position information acquired in step S18 to the server device 60 (step S19). ). The alarm information mediating unit 62 of the server device 60 receives the alarm information from the parent device 40 (step S20).

  Next, the alerting | reporting part 46 complete | finishes the alerting | reporting started by step S14 (step S21).

  And the main | base station 40 repeats the process with respect to the next identification information stored in the target object information storage part 12 from step S12.

  As described above, base unit 40 performs notification related to wireless tag 30 that satisfies the caution condition, and further transmits alarm information related to wireless tag 30 that satisfies the alarm condition to server device 60. The operation following the operation of the information processing system 2 will be described with reference to FIG.

  In FIG. 13, first, the alarm information mediating unit 62 of the server device 60 refers to the corresponding device information storage unit 61 for the alarm receiver 50 associated with the parent device 40 that received the alarm information received in step S20. This is specified (step S22).

  Next, the alarm information mediating unit 62 stores the received alarm information in the alarm information server storage unit 63 (step S23). At this time, the alarm information mediating unit 62 associates the received alarm information with the identification information of the receiving parent device 40 and the identification information of the alarm receiver 50 identified in step S22, and generates an alarm information server. You may make it store in the storage part 63. FIG.

  Next, the alarm information mediating unit 62 transmits the alarm information received in step S20 to the alarm receiver 50 identified in step S22 (step S24).

  Next, the alarm information receiver 51 of the alarm receiver 50 receives the alarm information (step S25). At this time, the alarm information receiving unit 51 stores the received alarm information in the alarm information storage unit 22.

  Next, the alarm information receiving unit 51 determines whether information instructing a request for retransmission of alarm information has been input (step S26).

  Here, when the information instructing the retransmission request is not input, the operation of the alarm receiver 50 proceeds to step S29.

  On the other hand, when information instructing a retransmission request is input, the alarm information receiving unit 51 transmits a retransmission request to the server device 60 (step S27).

  Next, the alarm information mediating unit 62 of the server device 60 refers to the alarm information server storage unit 63 to search for alarm information that has been transmitted to the alarm information receiver 50 that is the transmission source of the retransmission request. Then, the alarm information mediating unit 62 retransmits the searched alarm information to the alarm receiver 50 (step S28). The alarm information receiving unit 51 that has received the retransmitted alarm information stores the received alarm information in the alarm information storage unit 22.

  Next, the alarm detection position notification unit 53 notifies the position information included in the received alarm information (step S29). For example, as described above, the alarm detection position notification unit 53 may display a map image indicating the alarm detection position on the liquid crystal display 2003.

  Next, the discovery detection unit 55 acquires the reception status of the identification information included in the alarm information (step S30). For example, the discovery detection unit 55 may acquire a value representing the strength of a received radio wave from which the identification information is received by the identification information receiving unit 24 as the reception status.

  Next, the alarm detection position notifying unit 53 further notifies a value indicating the strength of the acquired received radio wave (step S31).

  Next, the discovery detection unit 55 determines whether or not the reception status of the identification information satisfies a predetermined discovery condition (step S32). For example, the discovery detection unit 55 may determine that the discovery condition is satisfied when a value representing the strength of the received radio wave including the identification information is equal to or greater than a threshold value.

  Here, when it is determined that the reception status of the identification information included in the alarm information does not satisfy the discovery condition, the alarm receiver 50 continues the operation from step S30.

  On the other hand, when it is determined that the reception status of the identification information included in the alarm information satisfies the discovery information, the discovery detection unit 55 ends the notification by the alarm detection position notification unit 53 (step S33). For example, the discovery detection unit 55 ends the display of the map image on which the image indicating the alarm detection position is superimposed and the display of the strength of the received radio wave. Accordingly, the discovery detection unit 55 may delete the corresponding alarm information stored in the alarm information storage unit 22. When the alarm information receiving unit 51 receives alarm information including other identification information in parallel, and the alarm information storage unit 22 stores a plurality of alarm information, the discovery detection unit 55 For the remaining alarm information stored in the alarm information storage unit 22, the processing from step S26 is repeated.

  In addition, the discovery detection unit 55 of the alarm receiver 50 notifies the server device 60 to delete the corresponding alarm information from the alarm information server storage unit 63 after determining that the discovery condition is satisfied in step S32. May be.

  Above, description of operation | movement of the information processing system 2 is complete | finished.

  Next, the effect of the second exemplary embodiment of the present invention will be described.

  The information processing system according to the second embodiment of the present invention can reduce the burden on the user of the alarm receiver while more reliably preventing loss of belongings.

  The reason is that the alarm detection unit of the master unit detects the wireless tag satisfying the precautionary condition before transmitting the alarm information regarding the wireless tag satisfying the alarm condition, and the notification unit relates to the wireless tag satisfying the precautionary condition. This is because an alert is issued. Thus, the information processing system according to the present embodiment does not transmit alarm information when the user of the parent device can cope with forgetting to carry his belongings. That is, the information processing system according to the present embodiment can more accurately determine the situation that requires notification to the user of the alarm receiver. As a result, the information processing system as the present embodiment reduces the burden on the user of the alarm receiver.

  Further, the server device mediates transmission / reception of alarm information between the master unit and the alarm receiver and accumulates alarm information, and the alarm information receiving unit of the alarm receiver makes a request for retransmission of alarm information. This is because the server apparatus retransmits the alarm information. As a result, even when the alarm receiver deletes the received alarm information due to an external cause, it can receive the alarm information again and reliably notify the alarm detection position. Therefore, the information processing system as the present embodiment can more reliably support the discovery of the belongings by the user of the alarm receiver.

  In each embodiment of the present invention, the alarm receiver is described as performing notification at the timing when alarm information is received. In addition, for example, when alarm information is received as mail, the alarm receiver performs notification at a timing when mail as alarm information is accessed by a mail client application based on an operation on the alarm receiver.
