Abstract

A storage section stores a history of a workflow for a plant in a specific status. A status detection section detects the status of the plant. A search section searches the history of the workflow for the plant that is stored in the storage section when the specific status is detected by the status detection section. A display displays the workflow extracted by the search section. An authority determination section determines whether an operator has an authority for an operation of the workflow extracted by the search section.

Claims

1. A plant information processing system for presenting information for supporting an operation of a plant, the plant information processing system comprising:

a storage section for storing history of a workflow for the plant in a specific status;

a status detection section for detecting a status of the plant;

a search section for searching the storage section for the history of the workflow for the plant in the specific status when the specific status is detected by the status detection section; and

a display for displaying information on the workflow extracted by the search section.

2. The plant information processing system according to claim 1, further comprising:

an authority determination section for determining whether an operator has an authority for an operation of the workflow extracted by the search section,

wherein the display displays the information on the workflow when the authority determination section determines that the operator has the authority for the operation of the workflow.

3. The plant information processing system according to claim 1, wherein the display displays a command for calling the workflow, and displays the workflow when the command is selected.

4. A plant information processing system for presenting information for supporting an operation of a plant, the plant information processing system comprising:

a logic storage section for storing a logic for suppressing an alarm in accordance with a status of a facility;

a status detection section for detecting the status of the facility; and

an alarm notification section for notifying a necessary alarm in accordance with a determination based on the logic stored in the logic storage section when a specific status is detected by the status detection section.

5. The plant information processing system according to claim 4, further comprising:

a prescribing section for prescribing a necessity of the notification of the alarm in association with a role of an operator,

wherein the alarm notification section notifies of the alarm to the operator of which role is associated with the necessity of the notification of the alarm prescribed in the prescribing section that the alarm notification is necessary.

6. A plant information processing method for presenting information for supporting an operation of a plant, the plant information processing method comprising:

storing history of a workflow for the plant in a specific status;

detecting a status of the plant;

searching the stored history for the history of the workflow of the plant in the specific status when the specific status is detected; and

displaying information on the workflow extracted by the search.

7. The plant information processing method according to claim 6, further comprising:

determining whether an operator has an authority for an operation of the workflow extracted by the search,

wherein the information on the workflow is displayed when it is determined that the operator has the authority for the operation of the workflow.

8. The plant information processing method according to claim 6, wherein a command for calling the workflow is displayed, and the workflow is displayed when the command is selected.

9. A plant information processing method for presenting information for supporting an operation of a plant, the plant information processing method comprising:

storing a logic for suppressing an alarm in accordance with a status of a facility;

detecting the status of the facility; and

notifying a necessary alarm in accordance with a determination based on the stored logic when a specific status is detected.

10. The plant information processing system according to claim 9, further comprising:

prescribing a necessity of the notification of the alarm in association with a role of an operator,

wherein the alarm is notified to the operator of which role is associated with the necessity of the notification of the alarm prescribed that the alarm notification is necessary.
