  First, if a parent or child who visits an amusement facility or department store wants a lost child notification service, he / she offers to the staff. The attendant gives the wireless IC tag 10 to the parent and the child, and associates the parent tag ID (for example, 1234A), the child tag ID (for example, 1234B), and the mail address to the user information database 321 of the management server 30 from a terminal (not shown). Register (see FIG. 2).

  Referring to FIG. 6, the parent and child always move in the facility with the wireless IC tag 10, and each IC tag reader 20 installed at a predetermined location in the facility communicates at a predetermined interval (for example, every 5 seconds). The tag ID is read from the wireless IC tag 10 existing within the range (step A1). Then, the IC tag reader 20 that has read the tag ID transmits the reader ID read from the memory (not shown) and the time information acquired from the clock unit (not shown) to the management server 30 together with the tag ID (step A2).

  The control unit 31 of the management server 30 stores the received information in the IC tag reading history database 323 (see FIG. 4). When the parent and child move slowly, a large number of the same tag IDs are stored in a short time corresponding to the same IC tag reader 20. For this reason, when a plurality of the same tag IDs corresponding to the same IC tag reader 20 are stored every 5 seconds, the control unit 31 leaves only the latest data and deletes others (step A3).

  Next, the control unit 31 refers to the IC tag reading history database 323 periodically (for example, every 30 seconds) (step A4), and sets a parent tag ID having a parent-child relationship and a child tag ID corresponding to the same reader ID. It is searched whether it is recorded within the time difference (for example, within 1 minute). Note that the parent tag ID and child tag ID having a parent-child relationship are acquired by the control unit 31 with reference to the user information database 321 (step A5).

In step A5,
(1) When the time difference between the parent tag ID and the child tag ID recorded for the same reader ID exceeds a predetermined time difference of 1 minute,
Or
(2) If one minute of a predetermined time difference has elapsed from one recording time and the other has not been recorded, the control unit 31 refers to the alarm notification history database 324 and applies the corresponding parent tag ID or child tag ID. It is searched whether alarm notification information corresponding to is stored. If it is stored, the control unit 31 determines whether or not a predetermined time or more (for example, 10 minutes or more) has elapsed since the last alarm notification time by comparing with the current time (step A6).

  If the predetermined time or more has not elapsed since the last alarm notification time, the processing is terminated. If the predetermined time or more has elapsed, the control unit 31 refers to the IC tag reading history database 323 and the child tag ID is the last. Is obtained. Then, the control unit 31 refers to the IC tag reader database 322, and acquires the installation location and LAN address of the corresponding IC tag reader 20 (see FIG. 3) (step A7).

  Next, the control unit 31 generates an e-mail notifying the child's whereabouts (the installation location of the IC tag reader 20 where the child tag ID was last read) and transmits it to the guardian portable terminal 40. At this time, for the mail address of the guardian portable terminal 40, the control unit 31 acquires the mail address registered in correspondence with the child tag ID from the user information database 321 (step A8). The parent knows the location of the distant child by looking at the mail received by the guardian mobile terminal 40 (step A9). Following step A8, the control unit 31 transmits an alarm notification to the IC tag reader 20 whose child tag ID was read last (step A10), and stores the alarm notification history in the alarm notification history database 324 (FIG. 5). (Refer to step A11). The IC tag reader 20 that has received the alarm notification, for example, notifies a predetermined announcement content (content indicating that a stray child has occurred in the vicinity) recorded in a recording medium (not shown) to the surroundings via a speaker or the like (step A12). . After that, searching for a child who seems to be lost by a staff member who has heard this announcement or who is in the vicinity of the IC tag reader 20 can quickly find a lost child.

Then, the IC tag reader 20 that has read the tag ID transmits the reader ID read from the memory (not shown) and the time information acquired from the clock unit (not shown) to the management server 30 together with the tag ID (step B2).

  The control unit 31 of the management server 30 stores the received information in the IC tag reading history database 323 (step B3). Next, the control unit 31 of the management server 30 refers to the latest data in the IC tag reading history database 323 and calculates the distance between the parent and child wireless IC tags 10 having a parent-child relationship for each parent and child. More specifically, the parent / child tag ID having the parent-child relationship is acquired from the user information database 321, and the reader ID from which the parent tag ID and child tag ID are read is acquired from the IC tag reading history database 323. Then, the position information (latitude, longitude) of the reader ID is acquired from the IC tag reader database 322. Thereafter, the control unit 31 calculates, for example, the difference between latitude and longitude based on the position information of the IC tag reader 20 from which the parent tag ID is read and the position information of the IC tag reader 20 from which the child tag ID is read. Is calculated (step B4).

  Next, the control unit 31 determines whether there is a parent or child whose distance is a predetermined distance or more (for example, 50 m or more) (step B5). When there is a parent and child that are separated by a predetermined distance or more, the control unit 31 refers to the alarm notification history database 324 and searches whether alarm notification information corresponding to the corresponding parent tag ID or child tag ID is stored. If it is stored, the control unit 31 determines whether or not a predetermined time or more (for example, 10 minutes or more) has elapsed since the last alarm notification time by comparing with the current time (step B6).

  If the predetermined time or more has not elapsed since the last alarm notification time, the processing is terminated. If the predetermined time or more has elapsed, the control unit 31 refers to the IC tag reading history database 323 and the child tag ID is the last. Is obtained. Then, the control unit 31 refers to the IC tag reader database 322, and acquires the installation location and LAN address of the corresponding IC tag reader 20 (step B7).

  Next, the control unit 31 generates a mail for notifying the child's whereabouts (the installation location of the IC tag reader 20 where the child tag ID was last read) and transmits it to the guardian portable terminal 40 (step B8). The parent knows the location of the distant child by viewing the mail received by the guardian mobile terminal 40 (step B9). Following step B8, the control unit 31 transmits an alarm notification to the IC tag reader 20 whose child tag ID has been read last (step B10), and stores the alarm notification history in the alarm notification history database 324 (step B11). ). The IC tag reader 20 that has received the alarm notification, for example, notifies the surroundings of predetermined announcement contents (contents indicating that a stray child has occurred in the vicinity) recorded on a recording medium (not shown) via a speaker or the like (step B12). .

  As described above, in one embodiment, when the wireless IC tag 10 of both the parent and child paired with the same IC tag reader 20 cannot be read within a predetermined time difference, a lost child occurrence alarm is notified. ing. If the same place is not passed within a predetermined time difference, it is assumed that the parent and child are separated and are in a lost state. In another embodiment, the IC tag readers 20 simultaneously read the wireless IC tags 10 at the same timing, and calculate the distance between the IC tag readers 20 that read the paired parent and child wireless IC tags 10. ing. When the calculated distance is greater than or equal to the predetermined distance, a lost child alarm is notified. As described above, in one embodiment or another embodiment, by analyzing and notifying the relative situation between the parent and child, the parent and child are in a lost state only by possessing the wireless IC tag 10. The effect of being detected immediately is sometimes obtained.

  Further, in the above-described embodiment or other embodiments, when the child is lost, the IC tag reader 20 that makes the child's whereabouts as the communication range announces the occurrence of the lost child, which leads to early detection. It is done.

  In the above-described embodiment or other embodiments, the guardian's portable terminal 40 is notified of the child's whereabouts when the child is lost, so that the guardian can pick up the child's whereabouts immediately. The effect that it can be obtained.

  Next, application examples and modification examples of the present invention will be described.

  In one embodiment or other embodiments described above, the alarm notification when a lost child occurs is described as being transmitted to the IC tag reader 20 whose communication range is the child's whereabouts. An alarm notification may also be transmitted to the IC tag reader 20. Regarding the definition of the vicinity, for example, the IC tag reader 20 closest to the IC tag reader 20 at the child's place and the IC tag reader 20 closest to the second are used, and the IC tag reader 20 to be notified for each IC tag reader 20 is managed in advance by the management server 30. Shall be registered in As a result, since the announcement of the lost child is circulated from the three IC tag readers 20 in the vicinity of the child's whereabouts, there is an effect that even if the child moves a little, it can lead to early detection.
