     The relay device  2  according to one embodiment of the present invention may receive a detection result as to whether a cover of a medicine case, which is a peripheral device of the tracking band monitoring system  0 , has been opened or closed. The medicine case may be configured to detect that the cover has been opened or closed and transmit the detection result by a sensor and a communication device installed, and the detection result having been transmitted to the relay device  2  via the wireless network may be transmitted to the server  3  by the relay means  21 . Further, the server  3  may determine that the monitoring target has taken medicine on condition that the server  3  receives the detection result. At that time, the server  3  may use only the fact that the cover of the medicine case has been opened or closed as a criterion of the determination. Further, the server  3  may stop the alert for preventing the monitoring target from forgetting to take medicine on condition that the server  3  determines that the monitoring target has taken medicine. 
     The server  3  has a management means  31  (management step) for associating a monitoring target identifier indicating the monitoring target and the band identifier and determining the monitoring data  0   d   3  based on the life log  0   d   11  and the band status  0   d   12  having been transmitted by the relay means  21 , a display means  32  (display step) for displaying a management screen  0   w  corresponding to the band identifier based on at least a part of the monitoring data  0   d   3 , and a control means  33  (control step) for determining a control signal  0   d   2  for controlling the tracking band  1  based on an intention input via the management screen  0   w , transmitting the control signal  0   d   2  to the tracking band  1  via the relay device  2 , and causing the tracking band  1  to execute the control signal  0   d   2 .

     A condition for an alert to be issued directed to the monitoring person and the monitoring target includes that an SOS button of the tracking band  1  is pressed, it is determined that there is a risk of heat stroke at the installation point of the relay device  2 , the setting time of the alert for preventing forgetting to take medicine comes, the vital data of the monitoring target deviates from the vital normal range, the server  3  receives information transmission by the nationwide instantaneous alert system (hereinafter, referred to as a J-ALERT), and the monitoring target goes out of the tracking area  0   a.    
     Further, the manner of the notification based on the known or conventional output device included in the computer device such as the tracking band  1 , the relay device  2 , or the server  3  may be changed depending on which condition the alert is issued. For example, when the setting time of an alert for preventing forgetting to take medicine comes, a voice transmission is made to inform that it is time to take medicine, and when a J-ALERT is received, such a warning sound that fuels a sense of crisis of the monitoring person and the monitoring target is made. 
     The management means  31  determines the tracking area  0   a  corresponding to the band identifier and the warning means  34  issues an alert for the monitoring person on condition that the location data indicates the outside area of the tracking area  0   a . The warning means  34  may issue the alert for the monitoring person on condition that the location data indicates being located in a predetermined area instead of or in addition to the fact that the location data indicates the outside area of the tracking area  0   a.    
     The management means  31  associates the location data indicating a movement path or the like indicating that the monitoring target is located outside the tracking area  0   a  with the monitoring data  0   d   3  as a wandering route. At this time, the wandering route may be associated with the monitoring data  0   d   3  at every predetermined time such as every day or may be associated with the monitoring data  0   d   3  every time the monitoring target returns to the tracking area  0   a  again after deviating from the tracking area  0   a.    
     The “tracking area  0   a ” in the description herein may refer to a predetermined area such as a city, a town, or a village and may refer to a range concentric around predetermined position coordinates.

     The tracking band  1  has a detection means  11  (detection step) for acquiring a life log  0   d   11  and transmitting the life log  0   d   11  and a band status  0   d   12  at least indicating a battery remaining amount of the tracking band  1  to the relay device  2  via a wireless network. 
     When the position of the tracking band  1  deviates from the tracking area  0   a , the detection means  11  acquires position information of the tracking band  1  by positioning using a GPS satellite in a conventional outdoor positioning mode and transmits location data of the tracking band  1  to the relay device  2  based on the result of the positioning. 
     The tracking band  1  may be attached with a seal member on which a low-dimensional code corresponding to the tracking band  1  is printed. The low-dimensional code may be generated or issued by the server  3  and may be associated with a monitoring target identifier and a band identifier. 
     The relay device  2  has a relay means  21  (relay step) for receiving transmission data from the tracking band  1  and the server  3 , performing data shaping of at least a part of the transmission data, and transmitting the transmission data to the server  3 , an identification means  22  (identification step) for identifying the band identifier in each of a plurality of tracking bands  1  of different models and the transmission data from each of the tracking bands  1 , an imaging means  23  (imaging step) for photographing a low-dimensional code, a reading means  24  (reading step) for reading the photographed low-dimensional code, and a display means  25  (display step) for displaying an application or a web page for inputting and outputting various information related to use of the tracking band monitoring system. 
     The relay device  2  is, as an example, a computer such as a smartphone, a tablet, and a laptop, which can be carried by a monitoring person and a family member or a relative of the monitoring target, etc. In this embodiment, a case is assumed in which a smartphone provided with a touch panel display as the display means  25  is used as the relay device  2 . However, besides this, any computer device that exerts the same operation and effect, such as a tablet terminal, may be used. Further, the relay device  2  interconnects with the tracking band  1  via a wireless network. Further, the relay device  2  interconnects with the server  3  via a wireless network. 
     The relay device  2  stores a web browser application for accessing an application and/or a web page for inputting and outputting various information related to use of the tracking band monitoring system in this embodiment. 
     The imaging means  23  photographs a low-dimensional code in response to an operation to the relay device  2  by a searcher. Here, there is no limit to the dimension, resolution, and image effect of the low-dimensional code related to the photographing processing. 
     The reading means  24  cooperates with the imaging means  23  to perform reading processing of the low-dimensional code, thereby acquiring detailed information about the monitoring target corresponding to the monitoring target identifier and the band identifier associated with the low-dimensional code. As an example, the reading means  24  recognizes a portion of the low-dimensional code from an image or printed matter representing the low-dimensional code and performs decoding processing of the portion. 
     The display means  25  displays an application or a web page for inputting and outputting various information related to use of the tracking band monitoring system. 
     &lt;Hardware Configuration&gt; 
     As illustrated in  FIG.  7   , the relay device  2  has an arithmetic unit  201 , a main storage device  202 , an auxiliary storage device  203 , an input device  204 , an output device  205 , a communication device  206 , an imaging device  207 , and a bus interface. Each of these devices is appropriately used in exerting the operation and effect of each means and each step included in the relay device  2  described above. 
     The communication devices  106  and  206  are each such a known network interface that enables interconnection between the tracking band  1  and the relay device  2  on the wireless network described above. The communication devices  206  and  306  are each such a known network interface that enables interconnection between the relay device  2  and the server  3  on the wireless network. 
     The imaging device  207  is such a known image sensor that enables reading processing and imaging processing. 
     &lt;Processing Sequence&gt; 
     As illustrated in  FIG.  8   , a tracking band search according to one embodiment of the present invention is performed according to the following procedures. First, the life log  0   d   11  including conventional location data indicating the position coordinates, the movement path, and the positioning result of the tracking band  1  is acquired by the tracking band  1 . Next, interconnection between the tracking band  1  and the relay device  2  is performed. At this time, the tracking band  1  transmits transmission data including the life log  0   d   11  and the band status  0   d   12  to the relay device  2 , and the relay device  2  receives the transmission data. After that, interconnection between the relay device  2  and the server  3  is performed and the relay device  2  transmits the transmission data to the server  3 . 
     As illustrated in  FIG.  8   , the server  3  determines the monitoring data  0   d   3  based on the life log  0   d   11  and the band status  0   d   12  having been transmitted from the tracking band  1 . After that, the server  3  updates the management screen  0   w  based on the monitoring data  0   d   3 . 
     As illustrated in  FIG.  8   , the server  3  transmits an email notifying the occurrence of wandering to a family member or a relative of the monitoring target, etc., and a person who has the relay device  2  and is in the vicinity of the monitoring target on condition that the location data indicates the outside area of the tracking area  0   a.    
     As illustrated in  FIG.  8   , the application stored in the relay device  2  is activated by specifying a URL written in the email. The relay device  2  acquires the band identifier of the tracking band  1  worn by the monitoring target from the server  3  on condition that the recipient of the email agrees to cooperate in a search for the monitoring target via the application. 
     In the description herein, a person who has received the email notifying the occurrence of wandering and agreed to cooperate in the search for the monitoring target is referred to as a “searcher”. 
     As illustrated in  FIG.  8   , the relay device  2  searches for the tracking band  1  based on the acquired band identifier, and when capturing a signal from the tracking band  1 , the relay device  2  issues an alert for the searcher and transmits the position information of the tracking band  1  to the server  3 . The position information of the tracking band  1  is acquired based on the strength of the signal captured by the relay device  2  and based on the three-point positioning method. 
     As illustrated in  FIG.  8   , the searcher presses a monitoring target information request button displayed on the display means  25 , whereby the relay device  2  acquires the monitoring target information from the server  3 . Here, the monitoring target information may include at least one of name, birth date, gender, physical features, and profile image  0   w   1  of the monitoring target. 
     As illustrated in  FIG.  8   , the searcher can make a telephone call to the predetermined call center by pressing a call button displayed on the display means  25  when the searcher has found the monitoring target and is able to confirm that the found person is the monitoring target. 
     As illustrated in  FIG.  8   , when the searcher has found the monitoring target and is not able to confirm that the found person is the monitoring target, the searcher reads the low-dimensional code attached to the tracking band  1  by using the imaging means  23  and the reading means  24  included in the relay device  2 , and then, can acquire detailed information related to the monitoring target and confirm whether the found person is the monitoring target by the monitoring target identifier associated with the low-dimensional code. Here, the detailed information that can be acquired by the relay device  2  is a part of information that can be displayed at least on the monitoring target profile display portion  0   w   2 . 
     As illustrated in  FIG.  8   , when the searcher is able to confirm that the found person is the monitoring target by reading the low-dimensional code, the searcher can make a telephone call to the predetermined call center by pressing the call button displayed on the display means  25 . 
     The location data according to one embodiment of the present invention may be configured to be acquired based on a terminal such as the tracking band  1  or the relay device  2  as appropriate in the form of a cloud GPS. 
     The tracking band  1  and the relay device  2  according to one embodiment of the present invention may include a waterproof and/or dustproof function. By including such a function, it becomes possible to detect the location of the monitoring target even when the monitoring target is caught in rubble or earth and sand in the event of disaster. 
     Further, in the tracking band monitoring system of the present invention, the relay means does not necessarily have to detect the tracking band via the wireless network, perform the positioning of the tracking band by interconnection via the wireless network, determine the location data of the tracking band based on the result of the positioning, and transmit the data to the server. 
     However, with such a configuration, it becomes easy to grasp the position of the tracking band even when the GPS function of the tracking band is turned off in order to suppress the power consumption of the tracking band, which is preferable. 
     Further, in the tracking band monitoring system of the present invention, the relay means does not necessarily have to receive the life log, which is the transmission data from the tracking band, perform data shaping of at least a part of the life log based on a predetermined data format, and transmit the life log to the server. 
     However, with such a configuration, the life logs based on the predetermined data format can be aggregated on the server regardless of the hardware configuration and the program configuration of a wide variety of tracking bands, which is preferable. 
     Further, in the tracking band monitoring system of the present invention, the detection means of the tracking band does not necessarily have to transmit both the vital data and the location data to the relay device and can transmit either one of the vital data or the location data to the relay device. 
     Along with this, the identification means of the relay device does not necessarily have to identify, based on the machine learning model, which vital data and location data in the tracking band monitoring system of the present invention both the vital data and the location data correspond to. 
     That is, the identification means of the relay device can identify, based on the machine learning model, which vital data or location data in the tracking band monitoring system of the present invention either one of the vital data or the location data corresponds to. 
     However, if the identification means identifies, based on the machine learning model, which vital data and location data in the tracking band monitoring system the vital data and the location data included in the life log having been received from the tracking band correspond to, it is preferable because data shaping according to the model of the tracking band worn by the monitoring target becomes possible even when the monitoring target replaces the tracking band. 
     Further, with such an identification means, both the vital data and the location data are used, so that it is preferable because, for example, when the monitoring target is in a dangerous situation, the monitoring person or the like can move to a place where the monitoring target is present to rescue the monitoring target. 
     Further, in the tracking band monitoring system of the present invention, the detection means of the tracking band does not necessarily have to transmit the band status to the relay device, and the management means of the server does not necessarily have to determine the monitoring data based on the band status. 
     However, if the monitoring data is determined based on the band status in addition to the life log, the status of the tracking band can also be grasped, so that it is preferable because the cause can be easily identified when the monitoring is delayed. 
     Further, in the tracking band monitoring system of the present invention, the server does not necessarily have to transmit an email notifying the occurrence of wandering to the relay device having the relay means and the identification means on condition that the location data indicates the outside area of the tracking area. 
     However, with such a configuration, a request for a search by a person having a relay device located in the vicinity of the monitoring target becomes possible, and it is preferable because quick protection is realized when the wandering or the like of the monitoring target occurs. 
     Further, in the tracking band monitoring system of the present invention, the server does not have to include the warning means for issuing, on the management screen in cooperation with the display means, an alert for the monitoring person for calling attention to an abnormality related to the monitoring target on condition that the location data indicates the outside area of the tracking area, and the management means does not necessarily have to determine the tracking area corresponding to the band identifier. 
     However, with such a configuration, the operation form in which wandering or the like of the monitoring target is immediately handled is realized, which is preferable. 
     Further, in the tracking band monitoring system of the present invention, the display means does not necessarily have to display the emergency contact code image corresponding to the tracking band on the management screen corresponding to the tracking band when the battery remaining amount is substantially zero. 
     Further, the terminal connected to the server does not necessarily have to read the emergency contact code image by using an image sensor, and does not necessarily have to acquire the band identifier associated with the emergency contact code image by succeeding in the reading and transmit a reading result, which is a result of the reading, including the band identifier to the server. 
     Further, the reading does not necessarily have to be a condition for causing the predetermined call center to perform a notification to the predetermined telephone number and/or email address corresponding to the band identifier. 
     However, with such a configuration, such suitable tracking band monitoring that can handle an unexpected situation in monitoring and protection of the monitoring target via the tracking band can be realized, which is preferable. 
     Further, in the tracking band monitoring system of the present invention, the control means does not necessarily have to cause the tracking band to execute the control signal, control at least one of the vibrator, the sound device, and the display device included in the tracking band, and issue an alert for the monitoring target. 
     However, with such a configuration, a power-saving alert and notification for the monitoring target by control via the relay device can be performed, which is preferable. 
     Further, in the tracking band monitoring system of the present invention, the control means does not necessarily have to determine the acquisition schedule of the life log acquired by the detection means by causing the tracking band to execute the control signal. 
     However, with such a configuration, the power consumption of the tracking band in the life log acquisition can be managed and adjusted, so that the operation period of the tracking band can be extended, which is preferable. 
     Further, in the tracking band monitoring system of the present invention, the management means does not necessarily have to associate the location data indicating that the monitoring target is located outside the tracking area with the monitoring data as a wandering route. However, with such a configuration, the wandering route of the monitoring target can be suitably managed, and the monitoring target can be suitably protected, which is preferable. 
     The present invention can provide a novel technique for realizing suitable tracking band monitoring by remotely performing monitoring and control related to the tracking band  1 .
