Abstract

Provided is a data management system including an environment data acquisition unit configured to acquire, from an environment sensor, environment data obtained by measuring a production environment where a product is produced from a raw material, a sensor selection unit configured to select a specific sensor from among measurement sensors, each of which is configured to measure a production target serving as a target of the production, according to a relevance with respect to the environment sensor, and a parameter setting unit configured to set a measurement parameter in the specific sensor based on the environment data.

First claim

What is claimed is:

1. A data management system comprising:
an environment data acquisition unit configured to acquire, from an environment sensor, environment data relating to at least one of a vibration, a temperature, a humidity, an illuminance, an odor, a gas concentration, a pressure, an air pressure, a stress, a magnetic field, a sound, and an image being outside a predetermined range, the environment data obtained by measuring a production environment where a product is produced from a raw material;
a sensor selection unit configured to select, when the environment data acquisition unit indicates the environment data of a first time period is outside the predetermined range, a specific sensor from among measurement sensors based on distance to the environment sensor, type of the physical quantity measured by the environment sensor, and a correlation between a time-series change of the environment data measured by the environment sensor and a time-series change of measurement data measured by the selected specific sensor, each of which is configured to measure a production target serving as a target of the production, according to a relevance with respect to the environment sensor; and
a parameter setting unit configured to set, when the environment data acquisition unit indicates the environment data has returned to the predetermined range, an initial measurement parameter in the selected specific sensor based on the environment data that has returned to the predetermined range.

2. The data management system according to claim 1 , wherein the sensor selection unit is configured to decide the relevance of the selected specific sensor based on the distance from the environment sensor.

3. The data management system according to claim 2 , wherein the sensor selection unit is configured to decide the relevance of the selected specific sensor based on the type of the physical quantity measured by the environment sensor.

4. The data management system according to claim 2 , wherein the sensor selection unit is configured to decide the relevance of the selected specific sensor based on the correlation between the time-series change of the environment data measured by the environment sensor and the time-series change of measurement data measured by the measurement sensor.

5. The data management system according to claim 2 , wherein the sensor selection unit is configured to decide the relevance of the selected specific sensor based on an actual record of being selected as the specific sensor.

6. The data management system according to claim 2 , further comprising:
a list output unit configured to output a list of candidate sensors as the selected specific sensor having the relevance higher than a predetermined threshold, wherein
the sensor selection unit is configured to select the specific sensor from among the candidate sensors according to a user input.

7. The data management system according to claim 2 , wherein the parameter setting unit is configured to change the measurement parameter when the environment data is out of a predetermined range.

8. The data management system according to claim 1 , wherein the sensor selection unit is configured to decide the relevance of the selected specific sensor based on the type of the physical quantity measured by the environment sensor.

9. The data management system according to claim 1 , wherein the sensor selection unit is configured to decide the relevance of the selected specific sensor based on the correlation between the time-series change of the environment data measured by the environment sensor and the time-series change of measurement data measured by the measurement sensor.

10. The data management system according to claim 1 , wherein the sensor selection unit is configured to decide the relevance of the selected specific sensor based on an actual record of being selected as the specific sensor.

11. The data management system according to claim 1 , further comprising:
a list output unit configured to output a list of candidate sensors as the specific sensor having the relevance higher than a predetermined threshold, wherein
the sensor selection unit is configured to select the specific sensor from among the candidate sensors according to a user input.

12. The data management system according to claim 1 , wherein the parameter setting unit is configured to change the measurement parameter when the environment data is out of a predetermined range.

13. The data management system according to claim 12 , wherein the parameter setting unit is configured to initialize the measurement parameter when the environment data is within the predetermined range.

14. The data management system according to claim 1 , wherein the parameter setting unit is configured to set a cycle for measuring the production target as the measurement parameter.

15. The data management system according to claim 1 , wherein the parameter setting unit is configured to set a sensitivity for measuring the production target as the measurement parameter.

16. The data management system according to claim 1 , further comprising:
a measurement data acquisition unit configured to acquire measurement data obtained by measuring the production target from the selected specific sensor; and
a data recording unit configured to record the measurement data.

17. The data management system according to claim 16 , wherein the data recording unit is configured to further record information indicating timing of setting change of the measurement parameter.

18. A data management method comprising:
acquiring, from an environment sensor, environment data relating to at least one of a vibration, a temperature, a humidity, an illuminance, an odor, a gas concentration, a pressure, an air pressure, a stress, a magnetic field, a sound, and an image being outside a predetermined range, the environment data obtained by measuring a production environment where a product is produced from a raw material;
determining that the environment data acquisition unit indicates the environment data is outside the predetermined range during a first time period, selecting, in response to determining that the environment data acquisition unit indicates the environment data is outside the predetermined range during the first time period, a specific sensor from among measurement sensors based on distance to the environment sensor, type of the physical quantity measured by the environment sensor, and a correlation between a time-series change of the environment data measured by the environment sensor and a time-series change of measurement data measured by the selected specific sensor, each of which is configured to measure a production target serving as a target of the production, according to a relevance with respect to the environment sensor; and
determining that the environment data acquisition unit indicates the environment data has returned to the predetermined range during a second time period, setting, in response to determining that the environment data acquisition unit indicates the environment data has returned to the predetermined range during the second time period, an initial measurement parameter in the selected specific sensor based on the environment data that has returned to the predetermined range.

19. A non-transitory computer-readable recording medium having recorded thereon a data management program that, when executed by a computer, causes the computer to function as:
an environment data acquisition unit configured to acquire, from an environment se
