It is a figure which illustrates the composition of the whereabouts information management system containing the whereabouts information management server in an embodiment. It is a figure which illustrates the structure of the whereabouts information management server shown in FIG. It is a figure which shows the Example of a beacon terminal. It is a figure which illustrates the whereabouts confirmation screen displayed on the screen of a guardian terminal.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In addition, the same code | symbol is attached | subjected to the same element and the overlapping description is abbreviate | omitted.

  FIG. 1 is a schematic configuration diagram of a location information management system including a location information management server (location information management device) according to an embodiment of the present invention. As shown in the figure, the whereabouts information management system 1 according to the present embodiment includes a whereabouts information management server 2, one or more watching terminals (detection terminals) 3, and one or more guardian terminals (user terminals). 4 and one or more beacon terminals (sending terminals) 5. Each of the watch-side terminal 3 and the guardian terminal 4 is configured to be able to communicate with the location information management server 2 via the network N.

  In the present embodiment, as illustrated in FIG. 3, a case where a child who has attached the beacon terminal 5 to the school bag R is watched is described. The watching target is not limited to a child, and may be any watching target such as a kindergarten or an elderly person.

  The beacon terminal 5 shown in FIG. 1 transmits a signal called a beacon (hereinafter referred to as a “beacon signal”) in order to notify the presence of the terminal itself. The beacon signal includes an identification ID that identifies the beacon terminal 5. By managing information that identifies a child in association with this identification ID, the position of the child can be identified based on the positional information of the watch-side terminal 3 that has detected the beacon signal and the identification ID of the beacon signal. It becomes possible.

  The beacon terminal 5 includes, for example, a transmission unit that transmits a beacon signal and an acceleration detection unit that detects the acceleration of the beacon terminal 5. The beacon terminal 5 is continuously detected for a predetermined time (third predetermined time) or longer by the acceleration detection unit and detects an acceleration less than a predetermined value (first predetermined value) (no acceleration is detected for a predetermined time or longer). (Including the case), the beacon signal transmission function from the transmission unit is turned off.

  For example, when the child arrives in the classroom and drops the school bag, the beacon terminal 5 stays in the same place. In such a case, it is only necessary to be able to notify the location specified most recently (for example, the location of a school gate or a shoebox), so the beacon signal transmission function is turned off (including power-off of the transmission unit). The battery consumption of the terminal 5 can be reduced and the life can be extended.

  In addition, the beacon terminal 5 turns on the function of transmitting a beacon signal from the transmission unit when acceleration equal to or greater than a predetermined value (second predetermined value) is detected continuously for a predetermined time (fourth predetermined time). (Including power ON of the transmitter). Thereby, when the class is finished and the child carrying the school bag starts going to school, the transmission of the beacon signal can be resumed.

  The predetermined time and the predetermined value, which are conditions for turning on / off the beacon signal transmission function, can be set as follows, for example. The predetermined value and the predetermined time when the transmission function is turned off can be set based on acceleration and elapsed time that can be determined to have shifted to a state where it is not necessary to detect the beacon signal. On the other hand, the predetermined value and the predetermined time when the transmission function is turned on can be set based on the acceleration and the elapsed time at which it can be determined that the beacon signal needs to be detected.

  In addition, in this embodiment, although demonstrated using the beacon terminal 5 as a terminal attached to the school bag R, it is not limited to this. Any transmitting terminal that can transmit a radio wave informing the presence of the terminal itself may be used. However, if the radio wave coverage is too small, it will be difficult to detect the calling terminal, and if the radio wave coverage is too large, it will be difficult to specify the exact location of the calling terminal. It is desirable to use a transmitting terminal that is about several meters to 50 meters.

As the type of the watch-side terminal 3, for example, a watcher's smartphone, a wireless communication terminal installed in a specific place, or the like can be set.

  By generating a detection signal to be transmitted to the location information management server 2 using one of the beacon signals detected in 5 minutes, the number of detection signals managed by the location information management server 2 can be reduced. It is possible to increase the processing efficiency.

  (3) When the watching application detects a beacon signal, the watching application does not display the fact that it has been detected on the screen of the terminal 3 on the side. The watching app displays, for example, the number of children watched on the previous day on the screen. Note that displaying the number of children is not limited to the previous day, and may be, for example, a past date designated by the watcher.

  The guardian terminal 4 is a smartphone used by a guardian (user) who applied for the child watching service provided by the whereabouts information management system 1, and an application for confirming whereabouts (hereinafter referred to as “location checking app”). Installed. The whereabouts confirmation application has the following functions, for example.

  (1) When the beacon terminal 5 registered by the location confirmation application is detected by the watch-side terminal 3 installed at a specific location, a notification indicating that the beacon terminal 5 has moved to the specific location is sent. 2 is received.

  Exemplarily, when the specific place is a school gate, when a beacon terminal 5 is detected in a preset school time zone, a school notification is received, and a beacon terminal 5 is detected in a preset school time zone Occasionally you receive a school notice.

  Thus, the parent who has received the school attendance notice or the school attendance notice can surely recognize that the child is in the elementary school by the initiative of the system side.

  (2) When a map is displayed on the guardian terminal 4 using the whereabouts confirmation application, an acquisition request for whereabouts information corresponding to the beacon terminal 5 registered with the whereabouts confirmation application is sent to the whereabouts information management server 2.

  Thereby, the position at the time of the detection of the watching side terminal 3 which detected the registered beacon terminal 5 is displayed on a map as a child's whereabouts. As illustrated in FIG. 4, the location of the child is displayed by a pin mark P. When the pin mark P on the map is selected, for example, the detection time and the type of the detected watching terminal 3 are displayed in the balloon frame B.

  In FIG. 4, one pin mark P is displayed on the map as the location of the child. However, the present invention is not limited to this. For example, two or more locations detected on the day (the number of locations may be set as an upper limit). ) Can be displayed on the map using pin marks indicating the respective locations.

  Moreover, you may enable it to confirm a child's moving route by displaying the arrow between pin marks in time series based on the detected time. Furthermore, it is good also as watching the color of several pinmarks and changing for every classification of the terminal 3 on the side. Further, the location of the child is not limited to being displayed on the map, and for example, a list including the detected time and place may be displayed on the screen.
