  Hereinafter, a search system according to an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 shows a block diagram of a search system according to an embodiment of the present invention. In FIG. 1, a search system 100 provides a search service for an object, and includes a terminal 200 possessed by a search requester, a search management server 300 possessed by a search service provider, and a search management server 300. A management database (DB) 310 as a storage means, a terminal 320 for operating the search management server 300, and vehicles 450-a and 450-b owned by search cooperators (hereinafter, these vehicles 450-a and 450). -B are collectively referred to as "vehicle 450" as appropriate, and the RFID tag detection devices 400-a and 400-b possessed by search cooperators (hereinafter, these RFID tag detection devices 400-a and 400-b are referred to as Collectively referred to as “wireless tag detection device 400” as appropriate) and RFID that is a wireless tag attached to a pet 550 that is an object of search Radio Frequency IDentification) communication network such as the Internet or a fixed telephone network that enables communication between the tag 500, the terminal 200 and the search management server 300, and communication between the search management server 300 and the wireless tag detection device 400 610, a mobile communication network 620, and base stations 630 and 640.
The terminal 200 is a terminal having a communication function such as a personal computer or a mobile phone. The terminal 200 performs communication for requesting a search to the search management server 300 via the base station 630, the mobile communication network 620, and the communication network 610 according to the request of the search requester, and the search management. A search result corresponding to the search request is received from the server 300 via the communication network 610, the mobile communication network 620, and the base station 630.

  The search management server 300 manages the entire search for an object. Specifically, the search management server 300 is a process for registering various types of information necessary for the search in the management DB 310, and for requesting a search to the wireless tag detection device 400 in response to a search request from the terminal 200. Processing, processing for notifying the terminal 200 of the search result based on the detection result of the RFID tag 500 from the wireless tag detection device 400, and the like are performed.

  The wireless tag detection device 400 is used by search partners, and is purchased or borrowed from a search service provider, for example. The wireless tag detection device 400 is a device having a communication function such as a mobile phone, a navigation device installed in the vehicle 450, and a PDA (Personal Digital Assistance). The wireless tag detection device 400 moves as the vehicle 450 driven by the search partner moves. Then, the wireless tag detection device 400 detects the RFID tag 500 during the movement, transmits the detection result to the search management server 300, or uses the detection result to perform processing for searching for an object. The search result is transmitted to the search management server 300.

  The RFID tag 500 is used by a search client. For example, the RFID tag 500 is purchased or borrowed from a search service provider and attached to a pet 550 that is a search target. The RFID tag 500 has a range in which the power of a signal transmitted from the RFID tag detection device 400 becomes a predetermined value or more when the RFID tag detection device 400 is moving (for example, within 10 m from the RFID tag detection device 400). ) Is activated by being supplied with power by the signal. The RFID tag 500 transmits a signal including a tag ID that is identification information recorded in a built-in memory (not shown).

  The operation of the search system 100 configured as described above will be described. In the present embodiment, one person may serve as both the search requester and the search cooperator, or may be either the search requester or the search cooperator.

  First, prior to searching for an object, the search management server 300 performs processing for registering information related to a search requester (search requester information) and information related to a search collaborator (search collaborator information) in the management DB 310. . An example of search requester information registered in the management DB 310 is shown in FIG. 2, and an example of search collaborator information registered in the management DB 310 is shown in FIG.

  The search requester information shown in FIG. 2 includes a member number (member No.), member information, possessed tag ID, object-accompanying information, and notification method information. The member number is identification information of the search requester (member). The member information is various information related to the member, and includes information on the member's name, date of birth, and address. The owned tag ID is identification information of the RFID tag 500 owned by the member. The object-accompanying information is various pieces of information representing the characteristics of the object to which the RFID tag 500 owned by the member is attached, and is associated with the owning tag ID. This object-accompanying information indicates an attribute indicating whether the object is a pet or a person, information unique to the object such as a name (unique information), and appearance characteristics such as the height and weight of the object. Information (feature information) and image information obtained by photographing the object are included. Notification method information includes identification information of the terminal 200 and other devices used when a search result of a member who is a search requester is notified, notification to a fixed phone, notification to a mobile phone, notification to a FAX device, Information on a method used when a search result is notified to a member, such as notification by e-mail to a mobile phone or a personal computer (PC), is included.

  In the search requester information shown in FIG. 2, the member number and the owned tag ID are associated with each other. Therefore, the search management server 300 can discriminate each search requester and the RFID tag 500 used by the search requester by referring to the search requester information.

  On the other hand, the search cooperator information shown in FIG. 3 includes a member number (member No.), a member type, a detection device ID, and acquisition points. The member number is identification information of a person (member) who cooperates with the search in the search service. The member type is the search cooperation when the RFID tag detection apparatus 400 possessed by the search cooperator detects the RFID tag 500, or the search cooperator protects the object when the RFID tag 500 is detected by the radio tag detection apparatus 400. This is information for identifying the degree of search cooperation, such as search cooperation. In the following, a search cooperator who performs search cooperation by detecting the RFID tag 500 by the wireless tag detection apparatus 400 is referred to as an A member, and a search cooperator that performs search cooperation by protecting an object is referred to as a B member. The detection device ID is identification information of the wireless tag detection device 400 possessed by the search partner. Acquired points are given according to the degree of search cooperation, for example, when the search cooperator protects the object, and are updated as needed by the operator's operation, for example, according to the search cooperator's search cooperation. . A search cooperator can receive a privilege according to the number of points given to him. For this reason, search cooperation is promoted, and the quality of the search service is improved.

  The search management server 300 generates the search requester information and the search cooperator information according to the input operation of the terminal 320 by the operator, and registers them in the management server 310.

  As described above, the search requester information and the search collaborator information are registered in the management DB 310, so that the object can be searched.

  First, an embodiment (first embodiment) for searching for an object will be described. FIG. 4 shows a sequence diagram of the operation of the search system 100 of the first embodiment. First, when the terminal 200 requests a search request from the search management server 300, the search management server 300 generates search request information and distributes it to the wireless tag detection apparatus 400 (S101).

  FIG. 5 shows a flowchart of the operation of the search management server 300 during search request information generation and distribution. First, the search management server 300 determines whether or not a member number from the terminal 200 has been received (S1001). When receiving the member number, the search management server 300 transmits menu information to the terminal 200 (S1002). The terminal 200 generates a menu screen including various options related to the search according to the received menu information and displays it on a built-in display (not shown).

  Next, the search management server 300 determines whether or not the search request has been selected from the menu screen options displayed on the display of the terminal 200 by the search requester (S1003). The search requester operates the terminal 200 to select one of the menu screen options. In this case, when requesting a search for an object, the search requester performs an operation of selecting an option corresponding to the search request. The terminal 200 transmits a signal corresponding to the option selected by the search requester to the search management server 300. Then, the search management server 300 receives this signal and determines the option selected by the search requester.

  When the search request is selected, the search management server 300 selects the search requester information registered in the management DB 310 including the member number received in S1001. Then, the search management server 300 extracts the owned tag, the object-accompanying information, and the notification method information included in the selected search requester information, and transmits them to the terminal 200 (S1004). The terminal 200 generates a selection screen including options according to the received possession tag, the object incidental information, and the notification method information, and displays the selection screen on the display.

  Next, the search management server 300 determines whether or not the owner tag ID and the notification method information are selected from the selection screen options displayed on the display of the terminal 200 by the search requester (S1005). For example, the search requester operates the terminal 200 to select the tag ID (owned tag ID) of the RFID tag 500 attached to the pet 550 that is the search target, and also notifies according to the notification method desired. Select method information. The terminal 200 transmits a signal corresponding to the option selected by the search requester to the search management server 300. Then, the search management server 300 receives this signal to determine the owned tag ID and notification method information selected by the search requester.

  When the owned tag ID and the notification method information are selected, the search management server 300 generates search request information and registers it in the management DB 310 (S1006). An example of search request information registered in the management DB 310 is shown in FIG. The search request information shown in FIG. 6 includes a member number, a search target tag ID, target-accompanying information, notification method information, search start time information, and a distribution destination detection device ID. The member number is identification information of the search requester. The search target tag ID is the owned tag ID selected by the search requester, and is the tag ID of the RFID tag 500 attached to the pet 550 that is the search target. The object incidental information is the object incidental information corresponding to the search object tag ID, in other words, the object incidental information representing the characteristics of the pet 550 that is the object to be searched. The notification method information is notification method information selected by the search requester. The search start time information is information indicating the time when the search request information is generated, and is set by a clock (not shown) built in the search management server 300. The delivery destination detection device ID will be described later.

  Next, the search management server 300 searches for the search request information for the A member including the owned tag ID in the search request information generated in S1006, the owned tag ID and the object-accompanying information in the search request information generated in S1006. The search request information for the B member including is generated (S1007).

  Further, the search management server 300 distributes the search request information for the A member to the wireless tag detection device 400 possessed by the A member, and distributes the search request information for the B member to the wireless tag detection device 400 possessed by the B member. (S1008). Specifically, the search management server 300 refers to the member type of the search partner information registered in the management DB 310 shown in FIG. 3 and the detection device ID corresponding to this member type. Then, the search management server 300 determines the detection device ID corresponding to the member type of the A member as the detection device ID of the wireless tag detection device 400 to which the search request information for the A member is to be distributed, The detection device ID corresponding to the member type is determined as the detection device ID of the wireless tag detection device 400 to which the search request information for the B member should be distributed. Next, the search management server 300 distributes either A member search request information or B member search request information to the wireless tag detection device 400 corresponding to each determined detection device ID. Further, the search management server 300 sets the detection device ID of the wireless tag detection device 400 as the distribution destination as the distribution destination detection device ID in the search request information generated in S1006 among the search request information registered in the management DB 310. (See FIG. 6).

  Again, referring back to FIG. The wireless tag detection device 400 provided in the vehicle 450 receives the search request information for members from the search management server 300, moves with the movement of the vehicle 450, and the tag ID from the RFID tag 500 during the movement. Is received, tag IDs are collated (S102), and tag detection information is generated and output (S103).

  FIG. 7 shows a flowchart of the operation of the wireless tag detection apparatus 400 at the time of tag ID collation, generation and output of tag detection information. First, the wireless tag detection device 400 determines whether or not search request information for members from the search management server 300 has been received (S1101). Upon receiving the search request information for members, the wireless tag detection device 400 stores and holds the search request information for members in a memory (not shown). Further, the wireless tag detection device 400 determines whether or not the tag ID is received from the RFID 500 while moving with the movement of the vehicle 450 (S1102). Upon receiving the tag ID from the RFID 500, the wireless tag detection device 400 stores the tag ID as a detection tag ID in a built-in memory (S1103).

  Next, the wireless tag detection device 400 determines whether or not the search target tag ID in the member search request information matches the detection tag ID in the memory (S1104). If they do not match, the wireless tag detection apparatus 400 deletes the detection tag ID in the memory used for collation in S1104 (S1111), and determines whether or not the tag ID from the RFID 500 has been received (S1102). Repeat the operation. Since the detection tag ID is deleted in this manner, the wireless tag detection device 400 cannot recognize an object that is not a search target, so that the privacy of a person who manages the object is protected. .

  On the other hand, when the search target tag ID in the member search request information matches the detected tag ID in the memory, the wireless tag detection device 400 checks the same tag ID as the tag ID used for the verification in S1104. It is determined whether or not it has been performed within the past predetermined time T1 (S1105). For example, each time the RFID tag detection apparatus 400 determines that the search target tag ID and the detection tag ID match in S1104, the RFID tag detection apparatus 400 associates the matching tag ID with the time information at that time and stores them in the memory. . If the RFID tag detection apparatus 400 determines that the search target tag ID and the detection tag ID match in the subsequent tag ID verification in S1104, the matching tag ID and the same tag ID are stored in the memory. It is determined whether it is stored. Further, when the wireless tag detection device 400 determines that the same tag ID is stored in the memory, the wireless tag detection device 400 refers to the time information associated with the tag ID stored in the memory, and uses the time information. It is determined whether or not the indicated time is within the past predetermined time T1.

  The wireless tag detection apparatus 400 determines whether or not the tag ID from the RFID 500 has been received when the same tag ID as the tag ID used for the collation in S1104 is collated within the past predetermined time T1 ( S1102) The subsequent operations are repeated. As a result, it is possible to prevent generation of substantially the same tag detection information in S1107, which will be described later, and to generate tag detection information as necessary, and to reduce the processing burden. It becomes possible.

  On the other hand, if the RFID tag detection apparatus 400 has not collated the same tag ID as the tag ID used for collation in S1104 within the past predetermined time T1, it generates position information and time information (S1106). . For example, the wireless tag detection device 400 has a GPS (Global Positioning System) function, detects its own position, and generates position information. Alternatively, the wireless tag detection device 400 acquires position information of the base station 640 that is a communication partner, and uses the position information to detect its own position and generate position information. The position of the wireless tag detection device 400 does not necessarily match the position of the RFID tag 500, but the fact that the wireless tag detection device 400 has received the ID tag means that the RFID tag 500 having the ID tag has detected the wireless tag. Since it is present in the vicinity of the device 400 (for example, within 10 m), even if the position of the wireless tag detection device 400 is used instead of the position of the RFID tag 500, the quality of the search service does not deteriorate. In addition, the wireless tag detection device 400 acquires the current time using a built-in clock (not shown), and generates time information.

  Next, the wireless tag detection device 400 uses the tag ID (detection tag ID) determined to be matched in S1104, the position information (detection position information) and time information (detection time information) generated in S1106, and its own detection device ID. The included tag detection information is generated and stored in the memory (1107). An example of tag detection information is shown in FIG. Further, the wireless tag detection device 400 transmits the tag detection information in the memory to the search management server 300 (S1108).

  Next, the wireless tag detection device 400 determines whether or not the object-accompanying information is included in the search request information for members from the search management server 300 (S1109). If the object-accompanying information is not included, the wireless tag detection device 400 repeats the operation after the determination whether the tag ID from the RFID 500 is received (S1102). On the other hand, when the object-accompanying information is included, the person who owns the wireless tag detection device 400 is a B member and needs to perform search cooperation by protecting the pet 550 that is the search object. is there. For this reason, the wireless tag detection device 400 displays the information accompanying the object included in the search request information for the member (not shown) as information useful for protecting the pet 550 that is the object to be searched (not shown). S1110). Thereafter, the wireless tag detection device 400 repeats the operations after the determination (S1102) on whether or not the tag ID from the RFID 500 has been received.

  Again, referring back to FIG. The search management server 300 generates search result information in response to reception of the tag detection information and transmits it to the terminal 200 (S104).

  FIG. 9 shows a flowchart of the operation of the search management server 300 when generating and notifying search result information. First, the search management server 300 determines whether or not tag detection information from the wireless tag detection device 400 has been received (S1201).

  If no tag detection information has been received, the search management server 300 further determines whether or not a predetermined time T2 has elapsed since the start of search (S1202). Specifically, the search management server 300 refers to the search target tag ID and search start time information in the search request information shown in FIG. Then, when tag detection information including the search target tag ID has not yet been received, the search management server 300 calculates a difference between the current time and the search start time indicated by the search start time information, It is determined whether time T2 has elapsed. The predetermined time T2 is set for each search request information. For example, the initial value is 24 hours. The search management server 300 increases the predetermined time T2 by 24 hours each time an affirmative determination is made in S1202. In this case, the search management server 300 can perform operations after S1203 described later every 24 hours.

  When the predetermined time T2 has not elapsed, the search management server 300 repeats the operations after the determination (S1201) on whether or not the tag detection information has been received. On the other hand, when the predetermined time T2 has elapsed, the search management server 300 generates search result information including information (undiscovered information) indicating that the pet 550 that is the search object has not been found (S1203). The undiscovered information includes, for example, the search target tag ID and target incidental information in the corresponding search request information, and the search requester can grasp which search target is undiscovered. It is like that.

  Next, the search management server 300 processes the generated search result information according to the notification method indicated by the notification method information in the corresponding search request information, thereby generating an e-mail or the like including the search result information. Then, the information is transmitted to the terminal 200 specified by the notification method information (S1204). Thereafter, the search management server 300 repeats the operation after the determination (S1201) of whether or not the tag detection information has been received. The terminal 300 displays the contents of the e-mail or the like including the received search result information on the display. Accordingly, the search requester can recognize that the pet 550 that is the search target has not yet been found.

  On the other hand, if the search management server 300 determines that the tag detection information has been received in S1201, the search management server 300 generates search result information based on the tag detection information and registers it in the management DB 310 (S1205). Here, the search management server 300 may use the tag detection information as the search result information as it is, or add the incidental information in the search request information corresponding to the tag detection information to the tag detection information. Search result information may be generated.

  Next, the search management server 300 processes the generated search result information according to the notification method indicated by the notification method information of the corresponding search request information, thereby generating an e-mail or the like including the search result information. Then, it is transmitted to the terminal 200 specified by the notification method information (S1206). The terminal 300 displays contents such as an e-mail including search result information on a display. Thereby, the search requester can recognize that the pet 550 that is the object of the search has been found.

  If the notification method information in the search request information indicates a notification method that requires operator intervention, such as notification to a fixed telephone or a mobile phone, notification by FAX, etc., the search management server 300 The operations in S1204 and S1206 are not performed. In this case, the search result is notified by an operator's operation or the like.

  Thus, in the first embodiment, the wireless tag detection device 400 provided in the vehicle 450 can receive the tag ID from the RFID tag 500 while moving. Therefore, since the detection range of the RFID tag 500 is expanded as compared with the case where the wireless tag detection device 400 is fixedly installed, the possibility of detection can be improved. In addition, since the search management server 300 generates search result information including position information and time information, the search requester recognizes when and where the pet 550 that is the search target is found. Can do. Further, when receiving the tag ID from the RFID tag 500 attached to the pet 550 that is the object to be searched, the wireless tag detection device 400 detects its own position and generates position information. Since it is not necessary for the 500 to detect the position, the configuration of the RFID tag 500 can be simplified.

  Further, when the search management server 300 does not receive the tag detection information including the tag ID of the RFID tag 500 attached to the pet 550 that is a search target even after the predetermined time T2 has elapsed from the start of the search. Since search result information including undiscovered information is generated, the search requester can obtain a search result at a predetermined time period even when the search target is not found, and the search is continued. It is possible to confirm that Furthermore, since the search management server 300 registers information on the notification method requested by the search requester in the management database 310, the search management server 300 can appropriately notify the search result.

  In addition, the search management server 300 distributes search request information including information attached to the object only to the wireless tag detection device 400 used by a search cooperator who is a B member who protects the object, and the like. Since the tag detection device 400 displays the object incidental information on the display, it is possible to transmit the object incidental information as necessary, and the B member recognizes detailed information of the object necessary for the search cooperation. It becomes possible to do.

  Next, another embodiment (second embodiment) for searching for an object will be described. A sequence diagram of the operation of the search system 100 of the second embodiment is shown in FIG. First, when the terminal 200 requests a search request from the search management server 300, the search management server 300 generates search request information (S201). The operation when the search management server 300 generates search request information is the same as the operation from S1001 to S1006 in the flowchart shown in FIG.

  On the other hand, the wireless tag detection device 400 provided in the vehicle 450 moves as the vehicle 450 moves. When receiving the tag ID from the RFID tag 500 during movement, the wireless tag detection device 400 generates tag detection information and transmits it to the search management server 300 (S203). Specifically, as in the first embodiment, the wireless tag detection device 400 includes a tag ID (detection tag ID), detection position information, detection time information, and detection device from the RFID tag 500, as shown in FIG. Tag detection information including the ID is generated.

  When the search management server 300 receives the tag detection information from the wireless tag detection device 400 after generating the search request information in S201, the search management server 300 performs tag collation (S203), further generates search result information, and sends it to the terminal 200. Send.

  11 and 12 show flowcharts of operations of the search management server 300 at the time of tag ID verification, search result information generation, and transmission. First, as shown in FIG. 11, the search management server 300 determines whether or not the tag detection information from the wireless tag detection device 400 has been received (S2001). Upon receiving the tag detection information from the wireless tag detection device 400, the search management server 300 stores the tag detection information in a built-in memory (not shown) (S2002).

  Next, the search management server 300 determines whether or not the search target tag ID in the search request information generated in S201 of FIG. 10 matches the detection tag ID included in the tag detection information in the memory ( S2003). If they do not match, the search management server 300 deletes the tag detection information including the detection tag ID used for the collation in S2003 from the memory (S2006), and has received the tag detection information from the wireless tag detection device 400 or not. The operation after the determination (S2001) is repeated. By deleting the tag detection information in this manner, the search management server 300 cannot grasp the target object that is not the search target, and thus the privacy of the person who manages the target object is protected.

On the other hand, when the search target tag ID in the search request information matches the detection tag ID included in the tag detection information in the memory, the search management server 300 uses the same tag ID as the tag ID used for the collation in S2003. Is checked within the past predetermined time T1 (S2004). Specifically, the search management server 300, like the wireless tag detection device 400 in the first embodiment, every time it is determined that the search target tag ID and the detection tag ID match in S2003, the matching tag ID and the time Are stored in the memory in association with each other. If the search management server 300 determines that the search target tag ID and the detection tag ID match in the subsequent tag ID matching in S2003, the matching tag ID and the same tag ID are stored in the memory. It is determined whether or not it has been done. Further, when the search management server 300 determines that the same tag ID is stored in the memory, the search management server 300 refers to the time information associated with the tag ID stored in the memory, and indicates the time information. It is determined whether the time to be recorded is within a predetermined time T1 in the past.
When the search management server 300 collates the same tag ID as the tag ID used for collation in S2003 within the past predetermined time T1, whether or not the tag detection information from the wireless tag detection device 400 has been received. The operation after the determination (S2001) is repeated. Accordingly, it is possible to prevent generation of substantially similar search result information in S2005, which will be described later, to enable generation of search result information as necessary, and to reduce the processing burden. .

  On the other hand, if the search management server 300 has not collated the same tag ID as the tag ID used for collation in S2003 within the past predetermined time T1, the search result is based on the tag detection information in the memory. Information is generated and registered in the management DB 310 (S2005). Here, the search management server 300 may use the tag detection information as the search result information as it is, or add the incidental information in the search request information corresponding to the tag detection information to the tag detection information. Search result information may be generated. Thereafter, the search management server 300 repeats the operations after the determination (S2001) on whether or not the tag detection information from the wireless tag detection device 400 has been received. If the search management server 300 determines in S2003 that the search target tag ID in the search request information matches the detection tag ID included in the tag detection information in the memory, the operation of S2004 is not performed. The search result information may be generated and registered in the management DB 310 in S2005.

  Further, in parallel with the operation shown in FIG. 11, the search management server 300 determines whether or not search result information has been generated as shown in FIG. 12 (S2101). When the search result information has already been generated, the search management server 300 processes the generated search result information according to the notification method indicated by the notification method information of the corresponding search request information, thereby obtaining the search result information. The included electronic mail or the like is generated and transmitted to the terminal 200 specified by the notification method information (S2105). The terminal 300 displays contents such as an e-mail including search result information on a display. Thereby, the search requester can recognize that the pet 550 that is the object of the search has been found.

  On the other hand, when the search management server 300 has not generated the search result information, the search management server 300 further determines whether or not a predetermined time T2 has elapsed from the start of the search (S2102). Specifically, the search management server 300 performs the same operation as S1202 of FIG. 9 in the first embodiment. That is, the search management server 300 refers to the search target tag ID and the search start time information in the search request information shown in FIG. Then, when tag detection information including the search target tag ID has not yet been received, the search management server 300 calculates a difference between the current time and the search start time indicated by the search start time information, It is determined whether time T2 has elapsed.

  When the predetermined time T2 has not elapsed, the search management server 300 repeats the operations after the determination (S2101) on whether or not the search result information has been generated. On the other hand, when the predetermined time T2 has elapsed, the search management server 300 generates search result information including information (undiscovered information) indicating that the pet 550 that is the search target has not been found (S2103).

  Next, the search management server 300 processes the generated search result information according to the notification method indicated by the notification method information of the corresponding search request information, thereby generating an e-mail or the like including the search result information. Then, it is transmitted to the terminal 200 specified by the notification method information (S2104). Thereafter, the search management server 300 repeats the operation after the determination (S2101) of whether or not the tag detection information has been received. The terminal 300 displays the contents of the e-mail or the like including the received search result information on the display. Accordingly, the search requester can recognize that the pet 550 that is the search target has not yet been found.

  If the notification method information in the search request information indicates a notification method that requires operator intervention, such as notification to a fixed telephone or a mobile phone, notification by FAX, etc., the search management server 300 first Similar to the embodiment, the operations of S2104 and 2105 described above are not performed. In this case, the search result is notified by an operator's operation or the like.

  As described above, in the second embodiment, the search management server 300 checks the tag ID in place of the wireless tag detection device 400 as compared with the first embodiment. Therefore, it is possible to reduce the processing load of the wireless tag detection device 400 and simplify the device configuration.

  Next, an embodiment (third embodiment) for confirming continuation of search will be described. FIG. 13 shows a sequence diagram of the operation of the search system 100 of the third embodiment. First, the search management server 300 generates search continuation confirmation information for confirming with the search client whether or not to continue searching for the pet 550 that is the object, and transmits the search continuation confirmation information to the terminal 200 (S301). Next, when receiving search continuation response information, which is a response to the search continuation confirmation information, from the terminal 200, the search management server 300 performs a response (search continuation necessity response) according to this search continuation response information (S302).

  FIG. 14 shows a flowchart of the operation of the search management server 300 at the time of generation and transmission of search continuation confirmation information and the search necessity correspondence. First, the search management server 300 determines whether or not a predetermined time T3 has elapsed from the start of search (S3001). Specifically, the search management server 300 refers to the search start time information in the search request information shown in FIG. Then, the search management server 300 calculates the difference between the search start time indicated by the current time and the search start time information, and determines whether or not the predetermined time T3 has elapsed since the search start. The predetermined time T3 is set for each search request information, and the initial value is, for example, one month. Each time the search management server 300 makes an affirmative determination in S3001, the search management server 300 increases the predetermined time T3 by one month. In this case, the search management server 300 can perform operations after S3002 described later every other month.

  When the predetermined time T3 has elapsed, the search management server 300 generates search continuation confirmation information including the search target tag ID in the corresponding search request information, and the terminal 200 specified by the notification technique information in the search request information. Transmit (S3002). Note that the search management server 300 may generate search continuation confirmation information including the object incidental information associated with the search target tag ID in the search request information together with the search target tag ID. In response to the received search continuation confirmation information, the terminal 200 generates a selection screen for allowing the search requester to select whether or not to continue the search, and displays the selection screen on a built-in display. For example, the search requester operates the terminal 200 to select whether or not to continue searching for an object. The terminal 200 generates search continuation response information according to the selection of the search client and transmits it to the search management server 300. This search continuation response information includes information indicating whether or not to continue searching for an object and a search target tag ID in search continuation confirmation information. Next, the search management server 300 determines whether or not search continuation response information from the terminal 200 has been received (S3003).

  Furthermore, when the search management server 300 receives search continuation response information, the search management server 300 analyzes the search continuation response information and determines whether or not search continuation is instructed (S3001). When the search continuation is instructed, the search continuation management server 300 repeats the operations after the determination (S3001) on whether or not the predetermined time T3 has elapsed from the start of the search.

  On the other hand, when search continuation is not instructed, that is, when search termination is instructed, the search management server 300 deletes the search request information including the search target tag ID in the received search continuation response information from the management DB 310. (S3005). Furthermore, the search management server 300, when the wireless tag detection device 400 performs collation between the search target tag ID in the member search request information and the detection tag ID from the RFID tag 500 as in the first embodiment described above. Generates search end information including the search target tag ID in the received search continuation response information, and distributes it to the wireless tag detection device 400 (S3006). The wireless tag detection device 400 deletes the search request information for members including the search target tag ID in the received search end information from the built-in memory. Thereby, the search system 100 ends the search for the object.

  When the search management server 300 collates the search target tag ID in the search request information with the detected tag ID in the tag detection information from the wireless tag detection device 400 as in the second embodiment described above. The search management server 300 does not generate and distribute search end information including the search target tag ID in the received search continuation response information (S3006).

  As described above, in the third embodiment, the search management server 300 generates search continuation confirmation information and transmits it to the terminal 200 when the predetermined time T3 has elapsed from the start of the search, thereby searching the search requester. A determination is made as to whether or not continuation is necessary, and if there is no need to continue the search, a process for ending the search is performed. For this reason, it is prevented that the search that the search requester no longer desires is continued.

  Next, an embodiment (fourth embodiment) regarding the end of search will be described. FIG. 15 shows a sequence diagram of the operation of the search system 100 of the fourth embodiment. When the terminal 200 requests the search management server 300 to end the search, the search management server 300 performs a response corresponding to the search cancellation (search cancellation response) (S401).

  FIG. 16 shows a flowchart of the operation of the search management server 300 in response to search cancellation. First, the search management server 300 determines whether or not a member number from the terminal 200 has been received (S4001). When the search management server 300 receives the member number, the search management server 300 transmits menu information to the terminal 200 (S4002). The terminal 200 generates a menu screen including various options related to search according to the received menu information, and displays the menu screen on a built-in display.

  Next, the search management server 300 determines whether or not search cancellation has been selected from the menu screen options displayed on the display of the terminal 200 by the search requester (S4003). For example, when requesting cancellation of the search for an object, the search requester operates the terminal 200 to select an option corresponding to the search cancellation. In this case, the terminal 200 transmits a signal corresponding to the option selected by the search requester to the search management server 300. Then, the search management server 300 receives this signal and determines the option selected by the search requester.

  When search cancellation is selected, the search management server 300 selects the search request information registered in the management DB 310 that includes the member number received in S4001. Further, the search management server 300 extracts the search target tag ID and the target incidental information included in the selected search requester information, and transmits them to the terminal 200 (S4005). The terminal 200 generates a selection screen including options according to the received search target tag ID and target object information, and displays the selection screen on the display.

  Next, the search management server 300 determines whether or not the search target tag ID is selected from the selection screen options displayed on the display of the terminal 200 by the search requester (S4006). For example, the search requester operates the terminal 200 to select the tag ID (search target tag ID) of the RFID tag 500 attached to the pet 550 that is the target for which the search is to be canceled. The terminal 200 transmits a signal corresponding to the option selected by the search requester to the search management server 300. And the search management server 300 determines search object tag ID which the search client selected by receiving this signal.

  When the search target tag ID is selected, the search management server 300 deletes the search request information including the selected search target tag ID from the management DB 310 (S4006). Further, the search management server 300 is further configured so that the wireless tag detection device 400 detects the search target tag ID in the member search request information and the detection tag from the RFID tag 500 as in the first embodiment. When collating with the ID, search end information including the selected search target tag ID is generated and distributed to the wireless tag detection device 400 (S4007). The wireless tag detection device 400 deletes the search request information for members including the search target tag ID in the received search end information from the built-in memory. Thereby, the search system 100 ends the search for the object.

  When the search management server 300 collates the search target tag ID in the search request information with the detected tag ID in the tag detection information from the wireless tag detection device 400 as in the second embodiment described above. The search management server 300 does not generate and distribute search end information (S4007).

  Thus, in the fourth embodiment, the search management server 300 performs a process for terminating the search in response to a request from the search client. For this reason, it is prevented that the search that the search requester no longer desires is continued.

  The search management server 300 performs the operations shown in the sequence diagrams of FIGS. 4, 10, 13, and 13, and the operations shown in the flowcharts of FIGS. 5, 9, 11, 12, 14, and 16. For example, it can be realized by executing a program transmitted from a server via a communication network, a program stored in a built-in ROM, a program stored in a storage medium such as a CD-ROM, or the like. Similarly, the wireless tag detection apparatus 400 performs the operations shown in the sequence diagrams of FIGS. 4 and 10 and the operation shown in the flowchart of FIG. 7 in, for example, a program transmitted from a server via a communication network or a built-in ROM. It can be realized by executing a stored program or a program stored in a storage medium such as a CD-ROM.

  In the embodiment described above, the search management server 300 immediately distributes the generated search request information for members to the wireless tag detection device 400 as shown in FIG. 5. You may make it deliver at the timing of. Further, when distributing the search request information for members to the wireless tag detection device 400, the search management server 300 may select and distribute the search request information for members newly generated after the previous distribution. In this case, the search management server 300 compares the time indicated by the search start time information in the search request information shown in FIG. 6 with the previous delivery time, and the time indicated by the search start time information is after the previous delivery time. The search request information for members corresponding to certain search request information is distributed. As a result, the search management server 300 can minimize the distribution of search request information for members.

  Alternatively, the search management server 300 considers the case where the wireless tag detection device 400 could not receive at the time of distribution of the search request information for members in the past, the search request information for members already distributed in the previous distribution, The search request information for members already distributed in the past than the previous distribution may also be distributed. For example, when distributing search request information for members every 24 hours, the search management server 300 refers to the time indicated by the search start time information in the search request information shown in FIG. The search request information for members already distributed for three days can also be distributed again.

  Further, when the search management server 300 tries to transmit the search result information to the terminal 200, the search management server 300 has already acquired the search result information including the same tag ID as the tag ID included in the search result information within the past predetermined time. When transmitting to the terminal 200, transmission may not be performed. As a result, the search management server 300 transmits search result information including the same tag ID only once within a predetermined time, and a large number of search results for the same object are sent to the search requester in a short time. It is possible to prevent notifications from being made and to make notifications as necessary, and to reduce the processing load.

  Alternatively, the search management server 300 registers a plurality of search result information including the same tag ID in the management DB 310, and collects one (for example, the latest) of these or a plurality of search request information. May be transmitted to the terminal 200 only once within a predetermined time. As a result, as described above, the search management server 300 transmits search result information including the same tag ID only once within a predetermined time, and many search results for the same object are obtained in a short time. It is possible to prevent the search requester from being notified, enable notification as necessary, and reduce the processing load.

  In the above-described embodiment, the wireless tag detection device 400 includes the time information in the wireless tag detection information and transmits it to the search management server 300. However, when the search management server 300 receives the wireless tag detection information, the wireless tag detection information is built-in. The present time may be acquired by a clock (not shown), and time information may be generated and set in the RFID tag detection information.

  In the above-described embodiment, the wireless tag detection device 400 has the position detection function and the communication function. However, these functions may not be provided. In this case, for example, the present invention is applied even when a mobile phone having a position detection function by GPS and a wireless tag detection device connected to the mobile phone and not having a position detection function and a communication function are used. Can do.

  Furthermore, the present invention can be applied even when a non-contact type device capable of transmitting its own ID in response to a predetermined signal is used instead of the RFID tag 500.

  As described above, the search system, the search management device, the wireless tag detection device, the search method, the search management method, the wireless tag detection method, the search management program, and the wireless tag detection program according to the present invention move the wireless tag detection device. However, the identification information of the wireless tag can be received from the wireless tag, and the detection range is expanded as compared with the case where the wireless tag is fixedly installed. It is useful as a search system.
