[Server 20]
FIG. 4 is a block diagram illustrating a hardware configuration of the server.

  The server 20 includes a control unit 21, a communication unit 22, and a storage unit 23. These components are communicably connected to each other by a bus. The basic configuration of these components is the same as that of the corresponding components of the detection unit 10, and thus redundant description will be omitted.

  The server 20 may be provided in the same building as the room for the subject 70, or may be provided in a remote location and connectable via a network. For example, the server 20 may be a cloud server virtually constructed by a plurality of servers arranged on a network such as the Internet. The components are communicably connected to each other by a bus. The control unit 21 functions as an acquisition unit in cooperation with the communication unit 22.

  The control unit 21 receives the temperature and humidity, the captured image, the vital data, and the event notification from the detection unit 10 via the communication unit 22. The control unit 21 receives the correspondence record for the target person 70 from the staff terminal 40 via the communication unit 22. The correspondence record includes at least one of the amount of water intake, the amount of urination, the amount of defecation, and the body temperature of the subject 70. The amount of urination, the amount of defecation, and the amount of water intake may be the amount of urination, the amount of defecation, and the amount of water intake of the subject 70 within a predetermined time in the past, respectively. The predetermined time can be set arbitrarily, and may be, for example, 8 hours, 12 hours, or 24 hours. Since these correspondence records can be included in the care record, a part of the care record may be used as the correspondence record. The control unit 21 causes the storage unit 23 to store the received temperature, humidity, captured image, vital data, event notification, and correspondence record.

  The storage unit 23 stores, for each subject 70, temperature and humidity, captured images, vital data, event notifications, and correspondence records (care records). That is, the storage unit 23 stores the temperature and humidity, the captured image, the image of the human silhouette, the vital data, the event notification, and the correspondence record in association with information that can specify the target person 70 such as the name of the target person 70. .

  The control unit 21 determines whether a predetermined condition is satisfied based on the temperature and humidity and the corresponding record. The predetermined condition is a criterion for determining whether or not the subject 70 has a high possibility of suffering from heat stroke, and is set such that the possibility of having heat stroke is high when the predetermined condition is satisfied. . The control unit 21 causes the storage unit 23 to store the predetermined condition.

  FIG. 5 is a diagram illustrating an example of predetermined conditions for determining that the possibility of heat stroke is high.

  In the example of FIG. 5, the predetermined condition includes three conditions of first to third conditions. As a condition for the correspondence record, a water intake (within 8 hours) is set. For example, in the first condition relating to the temperature, when the temperature satisfies 35 ° C. or more, the predetermined condition is satisfied irrespective of the humidity and the water intake (corresponding record). That is, in this case, it is determined that the predetermined condition is satisfied only by the first condition. In the first condition, when the air temperature satisfies 31 ° C. to 34 ° C. and in the second condition, the humidity satisfies 10% or more, the predetermined condition is satisfied regardless of the water intake. That is, in this case, it is determined that the first condition and the second condition satisfy the predetermined condition. When the air temperature satisfies 28 ° C. to 30 ° C. in the first condition and the humidity satisfies 30% or more in the second condition, the predetermined condition is satisfied regardless of the water intake. In addition, when the temperature satisfies 24 ° C. to 27 ° C. in the first condition, the humidity satisfies 80% or more in the second condition, and the water intake satisfies 50 cc or less in the third condition, a predetermined condition is satisfied. Meet.

  The predetermined condition may include, as an AND condition, a condition relating to at least one of the urination amount, the defecation amount, and the body temperature instead of or in addition to the third condition. In this case, the urination volume and defecation volume are divided into three levels of "large", "medium", and "small" with the past average being "medium". The condition can be set as an easy-to-be-easy one. The thresholds for each of “large” and “small” can be appropriately set by experiments and the like. Further, for example, the body temperature may be divided into two stages of “high” and “medium” with the average of the past being “medium”, and if it corresponds to “high”, it may be set as a condition that is liable to heat stroke. . The threshold value corresponding to “high” can be appropriately set by experiments or the like.

  If the control unit 21 determines that the predetermined condition is satisfied based on the temperature and humidity and the correspondence record, the control unit 21 sends a notification of a warning that the subject 70 is likely to suffer from heat stroke via the communication unit 22 to the administrator terminal. 30 or to the staff terminal 40. The notification of the warning includes the ID information, and it is possible to know which subject 70 has a high possibility of suffering from heat stroke from the ID information.

For example, in the first condition relating to the temperature, when the temperature satisfies 35 ° C. or higher, the predetermined condition is satisfied irrespective of the humidity, the water intake (within 8 hours), and the activity amount. That is, in this case, it is determined that the predetermined condition is satisfied only by the first condition. Further, for example, in the first condition, the temperature satisfies 31 ° C. to 34 ° C., in the second condition, the humidity satisfies 5% or more, in the third condition, the water intake satisfies 200 cc or less, and in the fourth condition. In the case where the activity amount satisfies 200 cal or more, a predetermined condition is satisfied.

  FIG. 10 is a flowchart showing the operation of the server. This flowchart can be executed by the control unit 21 according to a program stored in the storage unit 23 of the server 20.

  The control unit 21 stores the correspondence record received from the staff terminal 40 in the storage unit 23 in association with the ID information added to the correspondence record (S201).

  The control unit 21 acquires the temperature and humidity by receiving the temperature and humidity from the detection unit 10 (S202). The control unit 21 causes the storage unit 23 to store the temperature and humidity in association with the ID information added to the received temperature and humidity.

  The control unit 21 acquires the activity amount of the subject 70 by calculating the activity amount based on the image of the person silhouette received from the detection unit 10 and the weight of the subject 70 (S203).

  The control unit 21 determines whether or not an instruction to change the predetermined condition, which is input by the administrator 90 at the administrator terminal 30, has been received from the administrator terminal 30 (S204). If it is determined that the instruction to change the predetermined condition has not been received from the administrator terminal 30 (S204: NO), the process proceeds to step S206.

  When the control unit 21 determines that the instruction to change the predetermined condition has been received from the administrator terminal 30 (S204: YES), the control unit 21 changes the predetermined condition based on the instruction, and sends the changed predetermined condition to the server 20. The predetermined condition transmitted and stored in the storage unit 23 is updated to the changed predetermined condition.

  The control unit 21 receives the currently set predetermined condition from the server 20, and determines whether or not the predetermined condition is satisfied based on the temperature and humidity, the correspondence record, and the activity amount (S206). When the control unit 21 determines that the predetermined condition is not satisfied (S206: NO), the process ends.

  If the control unit 21 determines that the predetermined condition is satisfied (S206: YES), the control unit 21 transmits a notification of a warning that the subject 70 is likely to suffer from heat stroke to the manager terminal 30 or the staff terminal 40 ( S207).

  The embodiment according to the present invention has the following effects.

  It is determined whether or not a predetermined condition is satisfied based on the temperature and humidity of the surrounding environment of the target person and the correspondence record for the responder. If it is determined that the predetermined condition is satisfied, a warning about the target person is notified. Thereby, heat stroke can be appropriately and effectively prevented according to the state of each subject.

  Further, the activity amount of the watching target is further acquired, and it is determined whether a predetermined condition is satisfied based on the temperature and humidity, the correspondence record, and the activity amount. This makes it possible to more appropriately and effectively prevent heat stroke, taking into account the state of each watching target in more detail.

  Further, the correspondence record includes at least any one of a subject's water intake, urination, defecation, and body temperature. This makes it possible to more appropriately and effectively prevent heat stroke in consideration of the correspondence record relatively closely related to heat stroke.

  Further, the predetermined condition is changed based on a user's instruction. Thereby, the heat stroke prevention effect can be further improved by considering the past heat stroke prevention effects.
