Abstract

A safety and health information reporting system including a wearable device, a metabolic index calculating part, an activity index calculating part, a safety and health status determining part and a determination result output part. The wearable device is worn by a living body. The metabolic index calculating part calculates a metabolic index which represents energy consumption of the living body, based on a detection signal of the wearable device. The activity index calculating part calculates an activity index representing an activity amount of the living body on a daily basis. The safety and health status determining part which determines a safety and health status of the living body, based on a comparison of the metabolic index and the activity index. The determination result output part outputs a determination result of the safety and health status determining part.

Claims

1. A safety and health information reporting system comprising:

a wearable device having a pulse wave sensor, a temperature sensor and a movement sensor, and which is worn by a living body;

a metabolic index calculating part which calculates a metabolic index MtI representing a characteristic of a metabolism of the living body, based on a detected signal from the pulse wave sensor and the temperature sensor which detect a status inside of the living body;

an activity index calculating part which calculates an activity index AcI representing a characteristic of an activity amount of the living body, based on a detected signal from the movement sensor which detect a status of a movement of the living body;

a safety and health status determining part which determines a safety and health status of the living body, wherein the safety and health status determining part determines the safety and health status by comparing the metabolic index MtI calculated by the metabolic index calculating part and the activity index AcI calculated by the activity index calculating part, with respective predetermined index values; and

a determination result output part which outputs the determination result from the safety and health status determining part,

wherein the safety and health status includes a living condition normal daily factor and health problem information, and

wherein the safety and health status determining part determines;

a period of sleeping which is calculated based on a start time of sleeping and an end time of sleeping;

a period of being active from the end time of sleeping to the start time of sleeping;

a period of resting from the end time of sleeping to the start time of sleeping;

a period of dining from the end time of sleeping to the start time of sleeping; and

whether a heath problem is found.

2. The safety and health information reporting system according to claim 1, wherein the metabolic index calculating part is configured to calculate the metabolic index, based on an output signal of the pulse wave sensor and an output signal of the temperature sensor.

3. The safety and health information reporting system according to claim 1, wherein the activity index calculating part is configured to calculate the activity index based on an output signal of the movement sensor.

4. The safety and health information reporting system according to claim 1, wherein the determination result output part outputs a determination result of the safety and health status determining part when the safety and health status determining part determines that the living body is in a state of sleeping.

5. The safety and health information reporting system according to claim 1, wherein the determination result output part outputs a determination result of the safety and health status determining part via an e-mail.

6. The safety and health information reporting system according to claim 1, wherein the determination result output part generates a graph including the activity index, the metabolic index and the determination result, and outputs the generated graph.

7. The safety and health information reporting system according to claim 1, further comprising

a placed device including a human detection sensor which detects the living body, wherein

the safety and health status determining part outputs information representing a health problem of the living body, based on a detection signal of the human detection sensor.

8. The safety and health information reporting system according to claim 1, wherein the safety and health status determining part outputs e-mail representing that the health problem is determined upon determination of the health problem.

9. The safety and health information reporting system according to claim 1, wherein

a safety and health status determining part is further configured to determine the health problem of the living body based on one of predetermined health problem conditions H_PN, H_PS and H_PE, and

the safety and health status determining part further determines the health problem based on:

AcI<

AcI_L and MtI>

MtI_H indicating the health problem condition H_PN,

AcI>

AcI_H and MtI<

MtI_L indicating the health problem condition H_PS, and

AcI<

AcI_LL and MtI<

MtI_LL indicating the health problem condition H_PE.

10. A safety and health information reporting system comprising:

a wearable device having a pulse wave sensor, a temperature sensor and a movement sensor, and which is worn by a living body;

a metabolic index calculating part which calculates a metabolic index MtI representing a characteristic of a metabolism of the living body, based on a detected signal from the pulse wave sensor and the temperature sensor which detect a status inside of the living body;

an activity index calculating part which calculates an activity index AcI representing a characteristic of an activity amount of the living body, based on a detected signal from the movement sensor which detect a status of a movement of the living body;

a safety and health status determining part which determines a safety and health status of the living body, wherein the safety and health status determining part determines the safety and health status by comparing the metabolic index MtI calculated by the metabolic index calculating part and the activity index AcI calculated by the activity index calculating part, with respective predetermined index values; and

a determination result output part which outputs the determination result from the safety and health status determining part,

wherein the safety and health status includes a normal daily factor and health problem information, and

the safety and health status determining part determines a status of safety of the living body as to whether the living body is in a usual status or not.

11. The safety and health information reporting system according to claim 10, wherein the determination result output part writes the status of safety of the living body in a subject of the email.

12. A safety and health information reporting system according to claim 10, wherein the determination result output part reports the unusual status when the safety and health status is determined to be an emergency health problem.
