In the example illustrated in FIG. 5, the “priority” of the subject whose “UID” is “toyo1” is “2”, and the priority is higher than the subject whose “UID” is “toyo2”. Show.

  Returning to the description of FIG. 1 again, the list storage unit 112 prioritizes the subjects according to the above-described priorities, and, for example, lists the subjects (sorted) in order of priority (sorted). (List). The list of subjects stored in the list storage unit 112 is displayed on the watching terminal device 40 and is used when confirming the safety of the subject. A specific example of the target person list will be described later.

  The control unit 12 is, for example, a processor including a CPU (Central Processing Unit) and the like, and comprehensively controls the AP server device 10. For example, the control unit 12 acquires a plurality of types of activity information for each target person from the activity data storage unit 312, and targets priority information indicating priority based on the acquired plurality of types of activity information for each target person. Generated for each person, and ranks the target person according to the generated priority information.

Specifically, for example, the control unit 12 increases the priority of the priority information when vital data such as heart rate, respiration, blood pressure, body temperature, blood glucose level, and arterial oxygen saturation is out of a predetermined range. . Moreover, the control part 12 changes the priority of priority information, for example based on the comparison result of the activity data acquired in the past, and the activity data newly acquired. And the control part 12 produces | generates the list which ranked the subject according to the priority of the produced | generated priority information, and transmits the produced | generated list to the monitoring terminal device 40 via the network NW.
The control unit 12 includes a data acquisition unit 121, a priority processing unit 122, a list generation unit 123, and a list output unit 124.

  The data acquisition unit 121 acquires various data used for the processing of the control unit 12. For example, the data acquisition unit 121 acquires target person information stored in the target person storage unit 311 of the DB server device 30. Further, the data acquisition unit 121 acquires, for example, activity data stored in the activity data storage unit 312 of the DB server device 30. That is, the data acquisition unit 121 acquires, for example, the activity data stored in the activity data storage unit 312 of the DB server device 30 for each target person.

  The priority processing unit 122 generates, for each target person, priority information indicating the priority level for detecting that the target person is in an emergency based on the acquired plural types of activity information for each target person. According to the degree information, a process for ranking the target person is performed. For example, the priority processing unit 122 changes the priority information by the following seven processes.

<Emergency call processing>
When the AP server device 10 receives an emergency call from the emergency call device 21, for example, the priority processing unit 122 increases the priority of the received user ID by “+5”.

<Threshold check>
The priority processing unit 122 determines whether vital data such as heart rate, respiration, blood pressure, body temperature, blood glucose level, and arterial blood oxygen saturation acquired from the activity data storage unit 312 exceeds a preset threshold value. judge. The vital data acquired from the activity data storage unit 312 is data measured by the sheet type sensor 22 and the measuring device 23. The priority processing unit 122 increases the priority by setting the priority of the user ID corresponding to the vital data to “+1” when the vital data exceeds a preset threshold value.

<Trend check>
The priority processing unit 122 acquires the latest activity data for each subject, and calculates trends (trends) such as life patterns, heart rates, average values of respiratory rates, and standard deviation values. The priority processing unit 122 compares the past trend with the acquired activity data, and when the past trend is out of a predetermined range of the past trend, the priority processing unit 122 sets the priority of the corresponding user ID to “+1”, Increase priority. For example, the priority processing unit 122 calculates an average value and a standard deviation value (an example of a statistic) of vital data for each day for each target person. The priority processing unit 122 changes the priority of the priority information based on the average value and standard deviation value of the vital data up to the previous day and the average value and standard deviation value of the vital data on the current day. Specifically, the priority processing unit 122 compares the average value and standard deviation value of the vital data up to the previous day with the average value and standard deviation value of the vital data on the current day, and calculates the average value of the vital data on the current day. When the standard deviation value changes by more than a predetermined threshold from the average value and standard deviation value of the vital data up to the previous day, the priority of the corresponding user ID is increased by “+1” to increase the priority.

  Further, the priority processing unit 122 determines whether there is a gradual increase tendency or a gradual decrease tendency of the vital data as compared with a few days ago. Increase priority by “+1”. For example, when the vital data tends to approach the threshold value of the threshold value check described above, the priority processing unit 122 determines that the target person is in a state of caution and the priority level of the corresponding user ID. "+1" to increase the priority. Thus, the priority processing unit 122 changes the priority of the priority information based on the temporal change of the vital data.

<Life rhythm check>
The priority processing unit 122 calculates the tendency (probability) of staying / leaving for each time zone, and when the present day's staying / leaving pattern is out of the calculated tendency (probability) of staying / leaving. The priority of the corresponding user ID is increased by “+1” to increase the priority.

<Lonely death risk check>
The priority processing unit 122 determines that there is a risk of loneliness when the user is not in bed even when the time zone where the user is in bed and there is no daytime activity data, and the corresponding user ID The priority is increased by “+1”.

<Check subjective symptoms>
The priority processing unit 122 increases the priority by setting the priority of the corresponding user ID to “+2” when the subjective symptom input from the terminal device 24 is other than “health”.

<Confirmed check>
The priority processing unit 122 lowers the priority by setting the priority of the corresponding user ID to “0” when the operator of the call center 4 is within a certain period after the safety confirmation is performed. That is, the priority processing unit 122 lowers the priority of the priority information when the safety confirmation is performed on the target person.

  The list generation unit 123 ranks the target person based on the priority of the priority information changed by the priority processing unit 122. In other words, the list generation unit 123 generates a list (list) of the target persons in which the target persons are sorted in order of priority, and stores the generated list of target persons in the list storage unit 112.

  The list output unit 124 acquires the list of subjects generated by the list generation unit 123 from the list storage unit 112 and outputs the list to the monitoring terminal device 40 via the network NW in the web display format (HTML format), for example.

The watching terminal device 40 (an example of a display device) is a terminal device for performing an operation of watching an object person when operated by an operator. The watching terminal device 40 displays, for example, a list of subjects based on the ranking given by the control unit 12. In FIG. 1, one watch terminal device 40 is illustrated for explanation, but a plurality of watch terminal devices 40 may be disposed in the call center 4.
The watching terminal device 40 includes an operation unit 41, a display unit 42, a storage unit 43, and a control unit 44.

The operation unit 41 is an input device operated by an operator such as a keyboard and a mouse. The operation unit 41 acquires various types of information associated with operator operations.
The display unit 42 is a display device such as a liquid crystal display device, for example, and displays various data such as a list of subjects and the latest activity data for confirming the status of the subjects.
The storage unit 43 stores information used for various processes of the watching terminal device 40. The storage unit 43 stores information such as a list of subjects acquired from the AP server device 10, for example.

  The control unit 44 is a processor including a CPU, for example, and controls the AP server device 10 in an integrated manner. The control unit 44 includes a list acquisition unit 441, a display processing unit 442, and a safety confirmation processing unit 443.

  The list acquisition unit 441 acquires a list of subjects (a list arranged in descending order of priority) generated by the AP server device 10 via the network NW. The list acquisition unit 441 acquires the target person information and the latest activity data from the DB server device 30 via the network NW when confirming the target person information and the latest activity data of the target person.

The display processing unit 442 executes processing for causing the display unit 42 to display display data (for example, a list of subjects) acquired by the list acquisition unit 441.
The safety confirmation processing unit 443 notifies the AP server device 10 that the safety confirmation is completed when the operator confirms the safety based on the list of subjects displayed on the display unit 42. By this notification, the AP server device 10 executes a process for lowering the priority of the target person whose safety is confirmed.

  Note that the operator confirms the safety of the target person in descending order of priority (for example, from the top of the display) in the list of target persons displayed on the display unit 42 when performing the watching work. Specifically, the operator operates the watch terminal device 40 to check the target person information and the latest activity data, and checks whether the target person is in an emergency state, for example, by telephone or the like. Confirm safety such as signs. In addition, the operator contacts the contact information in case of an emergency by telephone or SMS.

Next, the operation of the watching system 1 according to the present embodiment will be described with reference to the drawings.
6 and 7 are flowcharts showing an example of the operation of the watching system 1 according to the present embodiment.
In FIG. 6, first, the AP server device 10 determines whether or not an emergency call from the emergency call device 21 has been received (step S101). That is, the priority processing unit 122 of the control unit 12 determines whether or not the AP server device 10 has received an emergency call from the emergency call device 21. When the priority processing unit 122 receives an emergency call from the emergency call device 21 (step S101: YES), the priority processing unit 122 sets the priority of the corresponding user ID to “+5” (step S102), and the process is as shown in FIG. Proceed to step S121. Moreover, the priority process part 122 advances a process to step S103, when the emergency call from the emergency call apparatus 21 is not received (step S101: NO).
In the description of the flowcharts shown in FIGS. 6 and 7, when the priority is changed, the priority processing unit 122 associates the corresponding user ID with the priority information indicating the priority, and sets the priority. A description will be given assuming that the priority information is stored in the storage unit 111 and updated.

  In step S103, the priority processing unit 122 determines whether the acquired vital data exceeds a preset threshold value. Here, first, the data acquisition unit 121 acquires, for example, the latest vital data measured by the sheet type sensor 22 or the measurement device 23 from the activity data storage unit 312 of the DB server device 30. Then, the priority processing unit 122 determines whether the vital data acquired by the data acquisition unit 121 exceeds a preset threshold value.

  Here, the preset threshold is a numerical value that should be notified (doctor call) to a doctor medically or nursingly, and may be a predetermined range. That is, the priority processing unit 122 determines whether the vital data is outside a predetermined range. When the acquired vital data exceeds a preset threshold (step S103: YES), the priority processing unit 122 increments the priority of the corresponding user ID by “+1” (step S104), and performs processing. Proceed to step S105. In addition, when the acquired vital data does not exceed a preset threshold value (step S103: NO), the priority processing unit 122 advances the process to step S105 without changing the priority of the corresponding user ID. . As described above, the priority processing unit 122 increases the priority of the priority information when the vital data is out of the predetermined range. In addition, the priority processing unit 122 determines whether or not each of the plurality of types of vital data is out of the predetermined range and changes the priority. Therefore, the priority is changed by combining the plurality of types of vital data. Will do.

  In step S105, the priority processing unit 122 calculates an average value and a standard deviation value of vital data for each day. That is, the data acquisition unit 121 acquires vital data measured by the sheet type sensor 22 and the measuring device 23 from the activity data storage unit 312 of the DB server device 30. The priority processing unit 122 generates (calculates) the average value and standard deviation value of the acquired vital data for each day.

  Next, the priority processing unit 122 determines whether or not the average value and the standard deviation value of the vital data up to the previous day are significantly different (step S106). That is, the priority processing unit 122 compares the average value and the standard deviation value of the vital data up to the previous day with the average value and the standard deviation value of the vital data on the current day, and compares the average of the vital data on the current day. When the value and the standard deviation value deviate from the average value and the standard deviation value of the vital data up to the previous day by a predetermined threshold or more (step S106: YES), the priority of the corresponding user ID is set to “+1”. (Step S107), the process proceeds to Step S108. The priority processing unit 122 also determines that the average value and standard deviation value of the vital data on the current day are not more than a predetermined threshold value away from the average value and standard deviation value of the vital data up to the previous day (step S106: NO). In addition, the process proceeds to step S108 without changing the priority of the corresponding user ID.

  In step S108, the priority processing unit 122 determines whether there is a gradual increase tendency or a gradual decrease tendency of the vital data as compared to several days ago. If there is a gradual increase tendency or a gradual decrease tendency (step S108: YES), the priority processing unit 122 increments the priority of the corresponding user ID (+1) (step S109), and the process proceeds to step S110. Moreover, the priority processing part 122 advances a process to step S110, without changing the priority of a corresponding user ID, when there is no gradual increase tendency or a gradual decrease tendency (step S108: NO).

  In step S <b> 110, the priority processing unit 122 obtains the tendency (probability) of being in bed / out of bed for each time zone. In other words, the priority processing unit 122 calculates the tendency of bed / bed-out for each time zone based on the past bed / bed-out information measured by the sheet type sensor 22.

  Next, the priority processing unit 122 determines whether or not the tendency of being in bed / out of bed is out of step (step S111). That is, the priority processing unit 122 compares the latest (on the day) occupancy / exit pattern with the past occupancy / exclusion tendency to determine whether or not the occupancy / exclusion tendency is deviated. . When the priority processing unit 122 deviates from the tendency to stay or leave the floor (step S111: YES), the priority processing unit 122 increments the priority of the corresponding user ID (step S112), and the process proceeds to step S113. . If the priority processing unit 122 does not deviate from the tendency to stay or leave the floor (step S111: NO), the priority processing unit 122 proceeds with the process to step S113 without changing the priority of the corresponding user ID.

  In step S <b> 113, the priority processing unit 122 determines whether or not the subject is in bed even when the target person is in bed. The priority processing unit 122 advances the process to step S114 when the subject is in the bed even when the time zone is in the bed (step S113: YES). Moreover, the priority process part 122 advances a process to step S116, when a subject is not in bed even if it becomes a time zone of bed (step S113: NO).

In step S114, the priority processing unit 122 determines whether there is daytime activity data. The priority processing unit 122 is, for example, position information detected by the emergency call device 21, acceleration data, activity data measured by the measuring device 23, medication information input from the terminal device 24, or a trace that the terminal device 24 has been operated. Based on such information, it is determined whether there is daytime activity data. If there is daytime activity data (step S114: YES), the priority processing unit 122 proceeds with the process to step S116 without changing the priority of the corresponding user ID. Further, when there is no daytime activity data (step S114: NO), the priority processing unit 122 increments the priority of the corresponding user ID by “+1” (step S115), and the process proceeds to step S116.

  In step S116, the AP server device 10 receives a subjective symptom from the subject. The subjective symptoms from the subject are transmitted to the AP server device 10 by the terminal device 24.

  Next, the priority processing unit 122 determines whether the received subjective symptom is other than “health” (step S117). When the subjective symptom is other than “healthy” (step S117: YES), the priority processing unit 122 sets the priority of the corresponding user ID to “+1” or “+2” (step S118), and performs the process. Proceed to step S119. Further, when the subjective symptom is “healthy” (step S117: NO), the priority processing unit 122 advances the processing to step S119 without changing the priority of the corresponding user ID.

  Next, in step S119, the priority processing unit 122 determines whether or not the call center 4 is within a certain period from the safety confirmation time. If it is within a certain period from the confirmation time (step S119: YES), the priority processing unit 122 sets the priority of the corresponding user ID to “0” (step S120), and advances the processing to step S121. Moreover, the priority process part 122 advances a process to step S121, when it is not less than a fixed period from confirmation time (step S119: NO).

  In step S121, the list generation unit 123 sorts in order of priority. That is, the data acquisition unit 121 acquires the target person information from the target person storage unit 311 of the DB server device 30 and stores the acquired target person information in the list storage unit 112. The list generation unit 123 rearranges (sorts) the list of subjects stored in the list storage unit 112 in descending order of priority based on the priority of the priority information. The list generation unit 123 causes the list storage unit 112 to store the rearranged list of subjects.

  Next, the list output unit 124 updates the list screen (list display screen) of the call center 4 (step S122). That is, the list output unit 124 acquires the latest rearranged target person list stored in the list storage unit 112 and outputs the acquired target person list to the monitoring terminal device 40 via the network NW. . The list acquisition unit 441 of the watching terminal device 40 acquires the list of subjects from the AP server device 10, and the display processing unit 442 causes the display unit 42 to display the list of subjects. Thereby, the display of the list screen (list display screen) of the call center 4 is updated.

  Next, when the operator of the call center 4 confirms the list of subjects displayed on the display unit 42 of the watching terminal device 40 and executes safety confirmation for the subject with high priority, The safety confirmation processing unit 443 outputs a notification including the confirmation result to the AP server device 10 together with the user ID corresponding to the target person who performed the safety confirmation.

Next, the priority processing unit 122 determines whether or not there is a target person who has confirmed safety (step S123). That is, the priority processing unit 122 determines whether or not there is a target person who has confirmed safety based on the notification that the safety confirmation processing unit 443 of the watching terminal device 40 has output the safety confirmation. When there is a subject who has confirmed safety (step S123: YES), the priority processing unit 122 adds the result of confirming the safety of the subject to the list (step S124), and returns the processing to step S119. In this case, the priority processing unit 122 sets the priority of the corresponding user ID to “0” by the processing of step S119 and step S120.
Moreover, the priority process part 122 advances a process to step S125, when there is no subject who confirmed safety (step S123: NO).

In step S125, the priority processing unit 122 determines whether the priority is “1” or higher and the call center 4 is not confirmed for a certain period. The priority processing unit 122 increments the priority of the corresponding user ID by “+1” (step S126) when the priority is “1” or more and the call center 4 has not been confirmed for a certain period (step S125: YES). ), The process returns to step S101. This is for increasing the priority of the subject who has not been confirmed for a certain period of time and forgetting the confirmation of safety.
Further, when the priority is “0” or the confirmation of the call center 4 is within a certain period, the priority processing unit 122 returns the process to step S101, and the processes of steps S101 to S126 are repeatedly executed.
