Abstract

Machines existing in a plant are classified under a multilevel hierarchy and are displayed on a screen. A summary of a diagnosis result of one or more nondisplayed machines which is not displayed on the screen and is classified to a level lower than that of the machines displayed on the screen. Therefore, the diagnosis result of the nondisplayed machines can also be seen on the screen and oversights of machine management can be prevented.

Claims

1. A machine management system for managing machines existing in a plant, comprising:

a hierarchy display processing section that classifies the machines existing in the plant under a multilevel hierarchy and processes to display the classified machines on a screen hierarchically; and

a diagnosis result display processing section that processes to display a diagnosis result of each machine displayed on the screen and a summary of a diagnosis result of one or more nondisplayed machines which is not displayed on the screen and is classified to a level lower than that of the machines displayed on the screen.

2. The machine management system according to claim 1,

wherein the diagnosis result display processing section processes to display a summary showing a normal diagnosis result when all of the diagnosis result of the nondisplayed machines is normal, and

the diagnosis result display processing section processes to display a summary showing an abnormal diagnosis result when at least one of the diagnosis result of the nondisplayed machines is abnormal.

3. The machine management system according to claim 1,

wherein the diagnosis result display processing section processes to display the diagnosis result with an icon.

4. A machine management system for managing machines existing in a plant, comprising:

a hierarchy display processing section that classifies the machines existing in the plant under a multilevel hierarchy and processes to display the classified machines on a screen hierarchically; and

a diagnosis result display processing section that processes to display an alarm level of each machine displayed on the screen and the highest alarm level out of one or more alarm levels of one or more nondisplayed machines which is not displayed on the screen and is classified to a level lower than that of the machines displayed on the screen.

5. The machine management system according to claim 4, further comprising:

a selection display processing section that processes to selectively display a machine whose alarm level is equal to or greater than a predetermined level.

6. The machine management system according to claim 4,

wherein the diagnosis result display processing section processes to display the alarm level with an icon.

7. A machine management system for managing machines existing in a plant, comprising:

a hierarchy display processing section that classifies nodes existing in each level of the plant under a multilevel hierarchy and processes to display the classified nodes on a screen hierarchically; and

a diagnosis result display processing section that processes to display a state of each node displayed on the screen and a summary of a state of one or more nondisplayed nodes which is not displayed on the screen and is classified to a level lower than that of the nodes displayed on the screen.

8. The machine management system according to claim 7,

wherein the diagnosis result display processing section processes to display a summary showing a normal state when all of the states of the nondisplayed nodes is normal, and

the diagnosis result display processing section processes to display a summary showing a special state when at least one of the states of the nondisplayed nodes is special.

9. The machine management system according to claim 7,

wherein the diagnosis result display processing section processes to display the state with an icon.

10. A machine management system for managing machines existing in a plant, comprising:

a machine display processing section that processes to display the machines existing in the plant on a screen;

an operation section for a user of the machine management system to check on the screen a machine whose diagnosis result is abnormal; and

a diagnosis result display processing section that processes to display a diagnosis result of each machine existing in the plant,

the diagnosis result display processing section processes to display diagnosis results whose display patterns are different between a machine before being checked through the operation section and a machine checked through the operation section out of machines whose diagnosis results are abnormal.

11. The machine management system according to claim 10,

wherein the diagnosis result display processing section processes to blink a mark showing an anomaly as a diagnosis result of the machine before being checked, and

the diagnosis result display processing section processes to light the mark showing an anomaly as a diagnosis result of the machine checked.

12. The machine management system according to claim 10,

wherein when a new anomaly occurs in the machine checked through the operation section, the diagnosis result display section processes to display a diagnosis result of the machine with a pattern before being checked through the operation section.

13. The machine management system according to claim 10,

wherein the diagnosis result display section processes to display a first blinking mark corresponding to a machine reaching a date when is a designated number of days before a scheduled inspection date, and

the diagnosis result display section processes to display a first lighted mark when the machine is checked through the operation section.

14. The machine management system according to claim 10,

wherein the diagnosis result display section processes to display a second blinking second mark corresponding to a machine reaching a scheduled inspection date, and

the diagnosis result display section processes to display a second lighted mark when the machine is checked through the operation section.

15. The machine management system according to claim 13,

wherein the diagnosis result display section processes to display a second blinking second mark corresponding to a machine reaching a scheduled inspection date,

the diagnosis result display section processes to display a second lighted mark when the machine is checked through the operation section, and

a color of the first blinking mark and the first lighted mark is different from a color of the second blinking mark and the second lighted mark.

16. The machine management system according to claim 10,

wherein the machine display processing section classifies the machines existing in the plant under a multilevel hierarchy and processes to display the classified machines on the screen in tree hierarchy.

17. A message server for collecting a message informing an anomaly in a machine and storing the message in a database, comprising:

an anomaly detail acquisition section that accesses an abnormal machine based on the message, acquires an anomaly detailed information stored in the abnormal machine, and adds the anomaly detailed information to the message.

18. The message server according to claim 17,

wherein the message server stores an anomaly detail definition file having a definition information indicating an anomaly detailed information for each machine type, and

when the anomaly detail acquisition section adds the anomaly detailed information to the message, the anomaly detail acquisition section refers to the anomaly detail definition file to interpret the anomaly detailed information and acquires a character string information.

19. The message server according to claim 17,

wherein the anomaly detail acquisition section acquires the anomaly detailed information of the machine through a field communication server accessing the machine.

20. The message server according to claim 19,

wherein data output from the anomaly detail acquisition section is reformatted by a message formatting section to record to the database.

21. The message server according to claim 17,

wherein the information stored in the database is reflected on a display screen of an integrated machine management apparatus.

22. The message server according to claim 17,

wherein the information stored in the database is reflected on a display screen of an operation supervisory apparatus in a distributed control system.

23. The message server according to claim 22,

wherein the anomaly detail acquisition section, an anomaly detail definition file, and message formatting section are formed in the operation supervisory apparatus.
