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 which includes 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 representing energy consumption of the living body, based on a detection signal of the wearable device;

an activity index calculating part which calculates an index representing an amount of daily performance of an activity amount of the living body;

a safety and health status determining part which determines a safety and health status of the living body, based on a comparison between the metabolic index and the activity index; and

a determination result output part which outputs a determination result of the safety and health status determining part.

2. The safety and health information reporting system according to claim 1, wherein the metabolic index calculating part calculates 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 calculates 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 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.

5. The safety and health information reporting system according to claim 1, wherein the safety and health status determining part determines whether the living body is in a usual status or not.

6. The safety and health information reporting system according to claim 5, wherein the safety and health status determining part determines that the living body is in an unusual status when the living body is not in a usual status.

7. The safety and health information reporting system according to claim 5, wherein the safety and health status determining part determines whether the living body is in a status of resting or in a status of being active.

8. The safety and health information reporting system according to claim 7, wherein the safety and health status determining part determines whether the living body is in a status of sleeping when the living body is in the status of resting.

9. The safety and health information reporting system according to claim 7, wherein the safety and health status determining part determines whether the living body is in a status of dining when the living body is in the status of being active.

10. 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 status of sleeping.

11. 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 in e-mail.

12. The safety and health information reporting system according to claim 11, wherein:

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; and

the determination result output part writes the status of safety of the living body in a subject of the e-mail.

13. 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.

14. 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, and 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.

15. 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.
