In addition, in the present specification and claims, the term “lost child” is used not only for a child who has lost his / her whereabouts but also for an adult who has lost his / her whereabouts.

(System configuration, operation overview)
FIG. 1 shows a schematic configuration diagram of a lost child searching system according to an embodiment of the present invention. FIG. 1 also shows an overview of the processing of the present embodiment.

  As shown in FIG. 1, the lost child search system according to the present embodiment includes a center server 10 (may be called a search control device), and a registration terminal 20, a reception terminal 30, and a search terminal 40 are respectively provided. It is configured to communicate with the center server 10 via a network (such as a mobile phone network or the Internet).

  The center server 10 communicates with each terminal and stores management information to control information registration, update, search, and the like. Each of the registration terminal 20, the reception terminal 30, and the search terminal 40 is a portable wireless terminal such as a smartphone. The registration terminal 20 is a terminal that performs advance registration of lost child information. The reception terminal 30 is a terminal that makes a lost child search request. The search terminal 40 is a terminal used by a staff member for searching for lost children.

  The registration terminal 20, the reception terminal 30, and the search terminal 40 are terminals that are deployed in a facility and held by a staff member, for example. Each terminal may be provided with all of a pre-registration function, a lost child search reception function, and a lost child search function, or may have only a function according to the intended use. These functions are realized by, for example, an application downloaded from the network to the terminal. The registration terminal 20, the reception terminal 30, and the search terminal 40 may be collectively referred to as an attendant terminal. Note that the registration terminal 20 and the reception terminal 30 may not be portable radio terminals, but may be fixed terminals such as a PC having a registration function and a reception function. When a fixed terminal is used as the reception terminal 30, the position information of the reception terminal 30 in an example in which the position information of the fixed terminal is registered in the center server 10 to gradually expand the search range described later. Can be used as

  Further, as the registration terminal 20 and / or the reception terminal 30, a terminal held by a (lost child) parent can be used. Hereinafter, a terminal held by a lost parent is referred to as a parent terminal. When the parent terminal is used as the registration terminal 20 and / or the reception terminal 30, the parent terminal may be referred to as the registration terminal 20 and / or the reception terminal 30.

  With reference to FIG. 1, an outline of the operation of the system according to the present embodiment will be described. When the user enters the facility, character goods or the like having a lost child tag storing a tag ID are distributed. A lost child tag is a tag corresponding to near field communication, such as NFC and RFID. The lost tag may be an IC card such as Suica (registered trademark). The lost tag may be a medium printed with an optically read tag ID such as a barcode. The tag ID differs for each lost child tag.

  The registration terminal 20 reads the tag ID from the lost tag, and the registration terminal 20 transmits the tag ID, name, photo, contact information, etc. to the center server 10 to perform pre-registration (step 1). After that, for example, if the child is lost, the parent goes to the clerk, and the reception terminal 30 held by the clerk reads the tag ID from the lost child tag held by the parent, and the search includes the tag ID. The request is transmitted to the center server 10 (step 2). The parent may make a search request from the parent terminal. Upon receiving the search request, the center server 10 transmits information such as a photograph registered in association with the tag ID to the search terminal 40, thereby requesting the search terminal 40 for a lost child search (step 3). ). The center server 10 may request a staff member close to the position where the lost child is first confirmed to search for the lost child and perform control so as to widen the request range every time.

  When a certain staff member finds a lost child, the lost child discovery report is transmitted to the center server 10 using the search terminal 40 that is held. The center server 10 that has received the lost child discovery report transmits a lost child discovery notification to the reception terminal 30 (step 4).

  Hereinafter, an apparatus configuration and an operation example in the present embodiment will be described in more detail with reference to the drawings.

(Device configuration)
FIG. 2 shows a functional configuration example of the center server 10 according to the present embodiment.

The communication unit 11 is a functional unit that communicates with each terminal via a network. The registration unit 12 is a functional unit that registers (stores) information transmitted from the registration terminal 20 (or the parent terminal) in the database 15. The search unit 13 is a functional unit that searches the database 15 based on a lost child search request received from the reception terminal 30. The notification unit 14 is a functional unit that performs processing such as notifying the search terminal 40 of the lost child information extracted from the database 15 by the search unit 13.

  The database 15 is a storage unit that stores data such as a lost child information table and an attendant terminal information table. An example of the lost child information table is shown in FIG. 3, and an example of the clerk terminal information table is shown in FIG. As shown in FIG. 3, the lost child information table includes a tag ID, a child name, a photograph, a child characteristic, a telephone number, an expiration date, reception terminal information, a status, a search start time, and the like. As shown in FIG. 4, the clerk terminal information table includes a terminal ID, a telephone number, position information of the terminal that requested the lost child search, and a lost child ID during the search.

  The center server 10 in the present embodiment can be realized by causing a computer to execute a program describing the processing contents described in the present embodiment. That is, each function unit in the center server 10 executes a program corresponding to processing executed in each function unit of the center server 10 using hardware resources such as a CPU, a memory, and a hard disk built in the computer. Can be realized. Further, the program can be recorded on a computer-readable recording medium (portable memory or the like), stored, or distributed. It is also possible to provide the program through a network such as the Internet or electronic mail.

  FIG. 5 shows a functional configuration example of the attendant terminal 50 used as the registration terminal 20, the reception terminal 30, the search terminal 40, and the like.

  As shown in FIG. 5, the clerk terminal 50 includes a tag reading unit 51, a position information acquisition unit 52, a communication unit 53, an operation display unit 54, a control unit 55, and a data storage unit 56.

  The tag reading unit 51 is an NFC tag reader, for example, and has a function of reading a tag ID from a lost child tag. The position information acquisition unit 52 has, for example, a GPS function, and has a function of acquiring position information in accordance with a staff operation (control by an application). The location information acquisition unit 52 also has a function of periodically acquiring location information of the terminal and transmitting the location information to the center server 10 via the communication unit 53.

  The operation display unit 54 is a functional unit for inputting information for the staff to operate the terminal and displaying the information, and is, for example, a touch panel such as a smartphone. The communication unit 53 has a function of communicating with the center server 10 and other staff terminals.

  The clerk terminal 50 is given a terminal ID (which may be a telephone number) for identifying the terminal, and the terminal can be specified by the terminal ID. The terminal ID is stored in the data storage unit 56. The data storage unit 56 also stores lost child information and the like.

  The control unit 55 executes the application program for realizing the functions of the registration terminal 20, the reception terminal 30, the search terminal 40, and the like, so that the attendant terminal 50 becomes the registration terminal 20, the reception terminal 30, and the search terminal. It has a function of performing control for functioning as 40 or the like. Although not shown, the clerk terminal 50 also has a photography function and other functions provided in a general smartphone or the like.

  In the present embodiment, the parent terminal used as an alternative to the registration terminal 20 and the reception terminal 30 has the same configuration as the attendant terminal 50. By installing the application installed in the registration terminal 20 and the reception terminal 30 on the parent terminal, the application can be used as an alternative to the registration terminal 20 and the reception terminal 30.

(Operation example)
Hereinafter, an operation example of the lost child search system according to the present embodiment will be described with reference to a sequence diagram. In this operation example, the tag ID is divided into the child tag ID and the parent tag ID, but it is not always necessary to divide the tag ID into the child tag ID and the parent tag ID. That is, a parent and a child may have a tag with the same tag ID. In this case, at the time of pre-registration, one of the tag IDs of the parent and the child may be read.

  Further, when a family has two or more children (eg, brothers), a different tag ID is assigned to each child. Thereby, a parent can request a lost child for each of a plurality of children such as brothers.

<Pre-registration for lost child search>
FIG. 6 is a sequence diagram showing a pre-registration process for lost child search. An example of the operation of the pre-registration process will be described with reference to FIG.

  Step 101) At the entrance gate of a facility such as a theme park, the lost tag storing the tag ID embedded in the character goods by the attendant is distributed to the attendees (parents and children) with children. When distributing a lost child tag to a parent and a child, read the tag ID of the lost child tag for the parent and the lost child tag for the child with the tag reading unit 51 (tag reader) of the registration terminal 20 (or the parent terminal, the same applies hereinafter) for registration. The parent tag ID and the child tag ID are stored in the data storage unit 56 of the terminal 20. Here, for example, when a parent tag ID input instruction is displayed on the registration terminal 20 by a user operation, the parent tag ID is read, and when the child tag ID input instruction is displayed, the child tag ID is read. Thus, the parent tag ID is stored as the parent tag ID in the data storage unit 56, and the child tag ID is stored as the child tag ID. Note that such processing is not necessary when the parent and the child can be distinguished based on the tag ID value.

  Step 102) Next, the clerk takes a photograph (example of feature information) showing the features such as the clothes of the child at the time of admission with the registration terminal 20, and stores the photograph image in the data storage unit 56 of the registration terminal 20. To do. The photo may be a picture of a family member, a picture taken before and after the body to understand the characteristics of a child, or a video.

  Step 103) The clerk inputs the child's name, contact information (such as the phone number of the smart phone owned by the parent) and the expiration date on the registration form displayed on the registration terminal 20 by a predetermined operation, and presses the send button. By performing operations such as the above, the input information is transmitted to the center server 10 together with the parent tag ID, child tag ID, and photograph stored in the registration terminal 20. Hereinafter, lost child information is referred to as lost child information.

  Step 104) The registration unit 12 of the center server 10 receives the lost child information from the registration terminal 20, and registers (stores) the received lost child information in the database 15. After registration, the registration unit 12 of the center server 10 transmits information indicating registration completion to the registration terminal 20.

  Step 105) When the registration terminal 20 receives the information indicating the completion of registration, the information indicating the completion of registration is displayed on the registration terminal 20. After confirming this, the parent and child enter (wear) each with a lost child tag.

  The processing contents described above are basic processing in advance registration. At the time of pre-registration, information indicating the characteristics of the child (gender, height, clothes color, presence / absence of hat, etc.) may be input to the registration terminal 20 and registered in the center server 10 in addition to the photo. In addition, at the time of taking a picture, the registration terminal 20 may automatically detect a child's characteristics (height, clothes color) and automatically register the characteristics.

  Although the expiration date of the lost child search is not particularly limited, in the present embodiment, one day or a plurality of days can be designated. The registration unit 12 of the center server 10 checks whether or not the expiration date has passed at any time. If the expiration date has passed, the registration unit 12 of the center server 10 cannot use the target tag ID. That is, for example, a process of deleting the tag ID from the lost child information or setting a use permission flag in the lost child information to set the use disabled is performed.

  As already described, pre-registration (photographing, tag ID reading, lost child information registration) can be performed from a parent terminal having the same function. Further, the lost tag may not be distributed, but the one used when entering the park last time may be used, that is, the tag ID may be reused. Thereby, registration of lost child information can be simplified. In this case, a use permission flag may be provided in the lost child information and set to be usable.

<Search for lost children, start search>
Next, the operation of the lost child search system at the time of searching for a lost child and starting the search will be described with reference to the sequence diagram of FIG.

  Step 201) A parent who notices that a child has been lost informs a nearby attendant that the child has been lost.

  Step 202) The staff member who is informed that the parent has lost his / her child reads the parent tag ID of the parent's lost child tag by the tag reading unit 51 of the reception terminal 30 and stores the data storage unit of the reception terminal 30. 56.

  Step 203) The clerk presses (touches) the lost child search start button displayed on the reception terminal 30, for example, and the parent tag ID, the terminal ID of the reception terminal 30 and the generation of the lost child are received from the reception terminal 30. The location information (latitude, longitude, etc.) of the receiving terminal 30 as location information is transmitted to the center server 10.

  Steps 204 and 205) In the center server 10, the search unit 13 searches the database 15 with the parent tag ID to search for lost child information (child tag ID, name, feature, photograph, etc.) corresponding to the parent tag ID. While extracting as lost child information, the terminal ID of the receiving terminal 30 is registered in the lost child information table of the database 15 in association with the searched lost child information, and the status is set to search.

  Step 206) The notification unit 14 of the center server 10 searches for the lost child information (child tag ID, name, feature, photo, etc.) and the location information of the reception terminal 30 registered in the staff terminal information table (FIG. 4). To the terminal 40 for use. In the clerk terminal information table, the search terminal 40 may be distinguished by the terminal ID, and the registration terminal 20 and the reception terminal 30 identify the search terminal 40 without distinguishing the terminal type. You may also serve.

  Step 207) The search terminal 40 (two are shown in FIG. 7) that received the lost child information and the position information of the reception terminal 30 from the center server 10 is the application (control unit 55) of the terminal. The function notifies a staff member of a search for a lost child by ringing, displays lost child information such as a photo of the lost child, and displays the position of the lost child (the position of the reception terminal 30) on the map. The search terminal 40 stores the lost child information received from the center server 10 in the data storage unit 56.

  Step 208) The notification unit 14 of the center server 10 transmits information indicating that the search for the lost child is started to the reception terminal 30 that has requested the search. As a result, information indicating that the search is being performed is displayed on the reception terminal 30. Each staff member having the search terminal 40 confirms the lost child information (photos and characteristics of the lost child) and the position, and starts searching for the lost child.

  In the above example, the position information of the reception terminal 30 is transmitted from the reception terminal 30 to the center server 10, but the position information to be transmitted is not limited to this. For example, the position where the clerk heard from the parent is lost is input to the reception terminal 30 (example: a map is displayed on the reception terminal 30 and input), and the input position is the position of the lost place. You may send it.

<When a lost child is found>
Next, an operation example of the lost child search system at the time of lost child discovery will be described with reference to the sequence diagram of FIG. In the following example, it is assumed that a staff member having the search terminal 40-1 finds a lost child.

  Steps 301 and 302) The staff member who finds the lost child reads the child lost child tag possessed by the lost child (reads) by the tag reading unit 51 of the search terminal 40-1, obtains the child tag ID, and searches the search terminal 40. -1 data storage unit 56.

  Step 303) Further, the search terminal 40-1 reads the child tag ID and tag reading unit 51 of the lost child that is being received from the center server 10 and stored in the search terminal 40-1 at the start of the search. Check the child tag IDs to see if they match.

  Step 304) If the child tag IDs match as a result of the collation and it is confirmed that the found lost child is a lost child being searched, the search terminal 40 displays the search terminal 40-1 on the search terminal 40-1, for example, by a staff member. The child tag ID and its position information are transmitted to the center server 10 when the lost child discovery button is pressed. Moreover, you may take a picture of the lost child at this time and send it together.

  Steps 305 and 306) In the center server 10 that has received the child tag ID and position information of the lost child from the search terminal 40-1, the search unit 12 sets the reception terminal ID corresponding to the received child tag ID to the database 15 (lost child). Information from the information table), and the position information of the search terminal 40-1 possessed by the staff member who found the lost child and the child tag ID are transmitted to the reception terminal 30 of the ID.

  Step 307) The reception terminal 30 that has received the child tag ID and the location information of the search terminal 40-1 that has found the lost child from the center server 10 notifies the staff (sounding, screen display, etc.) for search. The position of the terminal 40-1 is displayed. The position of the search terminal 40 is displayed on a map of a theme park, for example. Thereafter, the parent (person) goes to pick up the child to the position of the search terminal 40-1.

  Step 308) The notification unit 14 of the center server 10 searches for the child tag ID of the lost child and information indicating that the lost child has been found, and a search terminal possessed by another staff member who has been searching (has not found the lost child) 40 (search terminal 40-2 in the example of FIG. 8).

  Step 309) Upon receiving the information indicating that the lost child has been found and the child tag ID of the lost child, the search terminal 40-2 notifies the staff that the lost child has been found (ringing, screen display, etc.) The lost child information stored in the terminal 40-2 is deleted or changed to a discovered state.

  Step 310) The center server 10 deletes the terminal ID of the receiving terminal 30 in the lost child information table corresponding to the found child tag ID of the lost child, and changes the status to normal.

<Search for lost children, start search (start search using parent terminal)>
Next, an operation example in the case where the search is started using the parent terminal owned by the parent instead of the reception terminal 30 held by the attendant will be described with reference to FIG. In the following, it is assumed that the parent terminal has already read the parent tag ID.

  Step 401) A parent who realizes that a child has been lost starts searching for a lost child by pressing, for example, a lost child search start button at the parent terminal of the parent. The parent terminal that has pressed the lost child search start button transmits the parent tag ID and the position information of the parent terminal stored in the terminal to the center server 10.

  The subsequent processing is the same as the processing from step 204 described in FIG. When the parent terminal is used, the telephone number of the parent terminal is stored as the reception terminal ID in the lost child information table of the database 15, and communication from the center server 10 to the parent terminal is performed using the telephone number.

  Further, the process at the time of finding a lost child is the same as the process described in FIG. However, lost child discovery information is displayed on the parent terminal.

<Search for lost children, start search (specify search range, expand)>
In the examples described so far, the center server 10 notifies all the search terminals 40 of the lost child information at the start of the search and displays the lost child search screen on all the search terminals 40. It is also possible to display a lost child search screen on the search terminal 40 within the specified range by specifying and to gradually widen the search range according to the search situation. As a method for realizing this, in the present embodiment, there is a first method in which the center server 10 determines a search range and a second method in which the search terminal 40 determines whether to display a lost child search screen. . Each will be described below.

(1) First Method for Center Server to Determine Search Range An example of system operation in the first method will be described with reference to the sequence diagram of FIG.

  Step 504) In the center server 10 that has received the parent tag ID, position information, etc. from the reception terminal 30 (or parent terminal) in Steps 201 to 203 already described with reference to FIG. While searching for information (child tag ID, name, feature, photograph, etc.), the notification unit 14 determines a search terminal 40 that is a destination for notifying lost child information as follows.

  In the present embodiment, each terminal of the staff member periodically transmits the terminal position information to the center server 10, and the position information of the staff terminal information table in the database 15 is updated as needed. In addition, a threshold of a distance between the lost child occurrence point and the search terminal 40 is determined in advance as the range of the staff to be searched, and stored in the database 15 as setting information.

  The notification unit 14 of the center server 10 determines the distance between the lost child occurrence point and each search terminal 40 from the location information of the lost child occurrence point (position information of the reception terminal 30) and the position information of each search terminal 40. And the search terminal 40 whose distance is equal to or less than the threshold is selected. In the example of FIG. 10, the search terminal 40-1 is selected.

  Step 505) The notification unit 14 of the center server 10 registers the child tag ID of the lost child in the clerk terminal information table of the database in association with the terminal ID of the selected search terminal 40-1, and The terminal ID is registered in the lost child information table, and the status corresponding to the child tag ID of the lost child in the lost child information table is set to the searching state. Also, the search start time of the lost child is registered in the search start time field.

  Step 506) The notification unit 14 of the center server 10 transmits the lost child information (child tag ID, name, feature, photograph, etc.) and the location information of the reception terminal 30 to the selected search terminal 40-1.

  Step 507) The search terminal 40-1 that has received the lost child information and the location information of the reception terminal 30 from the center server 10 makes the search for the lost child sounded by the function of the application (control unit 55) of the terminal. Notifying and displaying lost child information such as a photo of the lost child, and displaying the position of the lost child (the position of the receiving terminal 30) on the map. The search terminal 40-1 stores the lost child information received from the center server 10 in the data storage unit 56.

  Step 508) The notification unit 14 of the center server 10 transmits information indicating that the search for the lost child is started to the reception terminal 30 that has made the search request. As a result, information indicating that the search is being performed is displayed on the reception terminal 30.

  Step 509) At the time of Step 506, the notification unit 14 of the center server 10 has started a timer, and a designated time (for example, 5 minutes after the search start time of the lost child) has elapsed, and When a lost child has not yet been found, the distance between the lost child occurrence point and each search terminal 40 is calculated again (the distance obtained in step 504 may be used), and the threshold value used in step 504 ( Using a threshold (second threshold) larger than the first threshold, a search terminal 40 (terminal that has not yet been searched) whose distance from the lost child occurrence point is equal to or less than the second threshold is selected. In the example of FIG. 10, the search terminal 40-2 is selected.

  The notification unit 14 of the center server 10 transmits the lost child information (child tag ID, name, feature, photograph, etc.) and the location information of the reception terminal 30 to the selected search terminal 40-2 and also the lost child. The tag ID is registered in the attendant terminal information table of the database 15 in association with the terminal ID of the selected search terminal 40-2.

  Thereafter, when the specified time has passed without a lost child being found, the same processing as above is repeated to widen the search range. Do this until a lost child is found.

When a lost child is found, the processing shown in FIG. 8 is performed. In this example, the notification unit 14 of the center server 10 is a clerk terminal (search terminal) whose child tag ID is registered in the clerk terminal information table. Only that the lost child has been found, and the child tag ID is deleted from the staff terminal.
(2) Second Method for Determining Whether Search Terminal Displays Lost Child Search Screen Refer to the sequence diagram of FIG. 11 for the second method for determining whether search terminal 40 displays the lost child search screen. To explain.

  Step 604) By the steps 201 to 203 already described with reference to FIG. 7, from the reception terminal 30 (or the parent terminal), the parent tag ID and the position information of the reception terminal 30 as the position information of the lost child occurrence point The center server 10 that has received and the like notifies the terminal 40 for searching by the notification unit 14 of the position information.

  Steps 605 and 606) Each search terminal 40 that has received the above information from the center server 10 determines whether or not to display a lost child search screen according to the distance from the lost child occurrence point as follows.

  A threshold of the distance between the lost child occurrence point (the above-mentioned position information) and the search terminal 40 is determined in advance as the range of the staff to be searched, and stored as setting information in the data storage unit 56 of each search terminal 40 Keep it. Each search terminal 40 calculates the distance between the lost child occurrence point and the search terminal 40 from the position information (lost child occurrence point) received from the center server 10 and the position information of the search terminal 40 (self). When the distance is less than or equal to the above threshold, a lost child search screen is displayed. Then, the search terminal 40 displaying the lost child search screen returns a lost child search start response to the center server 10. In the example of FIG. 11, the search terminal 40-1 returns a lost child search start response to the center server 10.

  Step 607) The notification unit 14 of the center server 10 registers the child tag ID of the lost child in the clerk terminal information table in association with the search terminal 40-1 that has returned the lost child search start response, and The status of the child tag ID is being searched. Also, the search start time of the lost child is registered.

  Steps 608, 609, 610) The notification unit 14 of the center server 10 transmits the lost child information and the position information of the reception terminal 30 to the search terminal 40-1 that has made a response to the start of lost child search. In addition, since the position information of the reception terminal 30 has already been transmitted, it may not be transmitted. Further, the reception terminal 30 is notified of the search start. Thereby, the lost child information is displayed on the search terminal 40-1 and the information indicating that the search is being performed is displayed on the reception terminal 30.

  Step 611) The notification unit 14 of the center server 10 activates the timer, the time specified from the start of the search (such as 5 minutes after the search start time of the lost child information) has passed, and the lost child has not yet been discovered. In this case, the position information of the lost child occurrence point is notified to all terminals again. Not all terminals but all terminals other than the terminal that has started searching may be notified. FIG. 11 shows the latter example, and the search terminal 40-2 receives the position information.

  Steps 612 and 613) The search terminal 40-2 that has received the position information uses a threshold (second threshold) larger than the threshold (first threshold) used in Step 605 to determine the distance between the lost child occurrence point and itself. A lost child search screen is displayed when is below the second threshold. In the example of FIG. 11, the search terminal 40-2 displays a lost child search screen and returns a lost child search start response to the center server 10.

  Thereafter, similarly to step 608 and subsequent steps, the child tag ID of the lost child is registered in the clerk terminal information table in association with the search terminal 40-2, and the lost child information or the like is transmitted to the search terminal 40-2. Such processing is repeated until a lost child is found.

  In this embodiment, when a plurality of lost children are generated and a plurality of lost children are searched for by one search terminal, a plurality of child tag IDs are registered as lost child tag ID2, lost child tag ID3, etc. in the clerk terminal information table. Is done.

  In addition, the selection of the staff member who performs the search (that is, the search terminal 40) predicts the moving range (moving distance) from the place where the child was lost and the time based on the information on the child's age, sex, indoors, and outdoors. It may be done.
