Abstract

An information management apparatus may include a first collection unit that collects a measurement value measured by a measurement device connected to the information management apparatus via a network, a second collection unit that collects status information indicating statuses of the measurement device and the network, and a correction unit that correcting quality information indicating validity of the measurement value, which has been collected by the first collection unit, by using the status information that has been collected by the second collection unit.

Claims

1. An information management apparatus comprising:

a first collection unit that collects a measurement value measured by a measurement device connected to the information management apparatus via a network;

a second collection unit that collects status information indicating statuses of the measurement device and the network; and

a correction unit that correcting quality information indicating validity of the measurement value, which has been collected by the first collection unit, by using the status information that has been collected by the second collection unit.

2. The information management apparatus according to claim 1, wherein

the quality information is added to the measurement value collected by the first collection unit, and

the correction unit corrects the quality information, which has been added to the measurement value, by using the status information that has been collected by the second collection unit.

3. The information management apparatus according to claim 1, wherein

the second collection unit collects device data of a path device included in the measurement device and the network in addition to the status information, and

the correction unit generates status information, which indicates a status of a measurement device or a path device, by using the device data, which has been collected by the second collection unit, if there is the measurement device or the path device of which status information is not obtained.

4. The information management apparatus according to claim 3, wherein

if there is a measurement device or a path device of which a plurality of pieces of status information are obtained, then the correction unit generates representative status information by combining the plurality of pieces of status information.

5. The information management apparatus according to claim 1, further comprising:

a display unit that displays the measurement value, which has been collected by the first collection unit, and the status information, which has been collected by the second collection unit, in parallel on the same time axis.

6. The information management apparatus according to claim 5, wherein the display unit comprises:

a first display area that displays time-series information regarding a process specified by a process identifier designated by a user; and

a second display area that displays time-series information regarding the measurement device specified by a device identifier designated by the user.

7. The information management apparatus according to claim 5, wherein the display unit has a filter function of selecting information to be displayed based on the user'"'"'s instruction.

8. An information management system comprising an information management apparatus and a display apparatus, wherein

the information management apparatus comprises:

a first collection unit that collects a measurement value measured by a measurement device connected to the information management apparatus via a network;

a second collection unit that collects status information indicating statuses of the measurement device and the network; and

a correction unit that corrects quality information, which indicates validity of the measurement value collected by the first collection unit, by using the status information that has been collected by the second collection unit, and

the display apparatus displays the measurement value, which has been collected by the first collection unit, and the status information, which has been collected by the second collection unit, in parallel on the same time axis.

9. The information management system according to claim 8, wherein

the quality information is added to the measurement value collected by the first collection unit, and

the correction unit corrects the quality information, which has been added to the measurement value, by using the status information that has been collected by the second collection unit.

10. The information management system according to claim 8, wherein

the second collection unit collects device data of a path device included in the measurement device and the network in addition to the status information, and

the correction unit generates status information, which indicates a status of a measurement device or a path device, by using the device data, which has been collected by the second collection unit, if there is the measurement device or the path device of which status information is not obtained.

11. The information management system according to claim 10, wherein

if there is a measurement device or a path device of which a plurality of pieces of status information are obtained, then the correction unit generates representative status information by combining the plurality of pieces of status information.

12. The information management system according to claim 8, wherein the display apparatus further comprises:

a display unit that displays the measurement value, which has been collected by the first collection unit, and the status information, which has been collected by the second collection unit, in parallel on the same time axis.

13. The information management system according to claim 8, wherein the display apparatus has a filter function of selecting information to be displayed based on the user'"'"'s instruction.

14. An information management method comprising:

a step of collecting a measurement value measured by a measurement device connected via a network;

a step of collecting status information indicating statuses of the measurement device and the network; and

a step of correcting quality information indicating validity of the measurement value, which has been collected, by using the status information that has been collected.

15. The information management method according to claim 14, wherein

the quality information is added to the measurement value collected by the first collection unit, and

the information management method further comprising:

a step of correcting the quality information, which has been added to the measurement value, by using the status information that has been collected.

16. The information management method according to claim 14, further comprising:

a step of collecting device data of a path device included in the measurement device and the network in addition to the status information, and

a step of generating status information, which indicates a status of a measurement device or a path device, by using the device data, which has been collected, if there is the measurement device or the path device of which status information is not obtained.

17. The information management method according to claim 16, further comprising:

a step of generating representative status information by combining the plurality of pieces of status information, if there is a measurement device or a path device of which a plurality of pieces of status information are obtained.

18. The information management method according to claim 14, further comprising:

a step of displaying the measurement value, which has been collected, and the status information, which has been collected, in parallel on the same time axis.

19. The information management method according to claim 18, further comprising:

a step of displaying time-series information regarding a process specified by a process identifier designated by a user; and

a step of displaying time-series information regarding the measurement device specified by a device identifier designated by the user.
