BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram of a plant monitoring apparatus according to an embodiment of the present invention; In the present embodiment, a plant such as a steam turbine, a gas turbine, and a combined power generation plant and components thereof are simply referred to as a “plant”.

FIG. 1 is a functional block diagram showing a plant monitoring apparatus according to this embodiment. FIG. 2 is a flowchart showing a flow of processing of the plant monitoring device. FIG.
FIG. 3 is a diagram showing an alarm list of a database device displayed on a screen of a CRT unit constituting the plant monitoring device. FIG. 4 is a diagram showing an example of an image of an abnormal event and a treatment item displayed on a screen of a terminal constituting the plant monitoring apparatus.

In FIG. 1, the present plant monitoring device 10
Is a control device (control unit) 1 and a CRT (cathode-
(ray tube) unit 2 and a terminal 3. The normal value of each part of the plant monitored by the plant monitoring device 10 is input to the control device 1, and the items of each part are controlled so as to hold the normal values.

For example, the temperature and level of the cooling water of the plant are controlled so as to maintain the normal values input to the control device 1, and the control state is detected by the cooling water detecting unit 11. Similarly, the control state of the rotation number of the actuator is detected by the rotation number detection unit 12, and the control state of the water level of the drum is detected by the drum water level detection unit 13. Other parts of the plant are similarly detected by the other detection unit 14.

The controlled values for each location, which are the detection results of the detection units 11, 12, 13, and 14, are C
It is transmitted to the CRT unit 2 in which a PU (central processing unit) is incorporated.

In the CRT unit 2, each of the detection units 11, 12, 1
Based on the data received from 3 and 14, a comparison 21, an operation 22, a storage 23, a determination 24 and the like are performed for each item. The abnormal event extraction unit 25 extracts an abnormality (failure event) of each detection unit based on the determination result and the like. The alarm number (failure number) stored in the alarm number storage unit 26 is read based on the data indicating the extracted failure event, and the read alarm number is displayed on a screen display unit (display unit).
The call is sent to 27.

The screen display 27 displays the received failure number 3
A failure list in the form of a list corresponding to the failure event 3 and the failure event 34 is displayed as shown in FIG. 3, and an alarm and a lamp flash on and off the failure event 34. Further, a printer 29 of the CRT unit 2 outputs a print 29 of an abnormal alarm portion as needed. On the screen display unit 27 or print 29,
The failure event 34 and the failure number 33 are classified into the event occurrence frequency order,
The urgency can be displayed with a high brightness, a red background, or the like, according to the order of the importance of the treatment items and the degree of urgency of the treatment items.

On the other hand, in the terminal 3, when an alarm number 33 (41) for which an alarm has been issued by the CRT unit 2 is inputted and searched by a key operation (51), the alarm number 33 (41) is previously input as a database to the terminal server 52. The event 42 and the processing item 43 are displayed on the terminal screen (53).
In the display screen 53 of the terminal 3, the failure events 42, 44
In addition, the treatment items 43 can be displayed with high brightness, a red background, or the like in the order of importance or event occurrence frequency.

As shown in FIG. 4, a screen 53 of the terminal 3 displays an alarm number 41, a failure event 42, and a measure 43 for the failure, an alarm name 44, which is the name of the failure, and the severity / minority of the failure. Type 45, reference screen 46 to be referenced when repairing the failure, set value 4 as a normal value during control
7 is displayed.

In the flowchart of FIG. 2, a normal value of each item is input to the control device 1 in advance (step S1), and control is performed based on the normal value (step S1).
2) Normal operation is maintained. The CPU incorporated in the CRT unit 2 continues to monitor the control result of the control device 1 (step S3), and continues to determine whether or not each item is abnormal (step S4, abnormal event extraction unit 25). If there is no abnormality (step S4-No), the CPU continues to monitor the control result (steps S2 and S3). When an abnormality is detected (step S4-Yes), the alarm number corresponding to the cause is blinked and an alarm is immediately issued on the screen of the CRT unit 2 (step S5), and printout is performed as necessary (step S6). ).

In the terminal 3, when the alarm number displayed on the screen of the CRT unit 2 is input by operating the keys of the terminal 3 (step S7), the abnormal event 42 and its The processing item 43 is output (step S8). The abnormal event 42 is an event resulting from the failure of the alarm name 44 (34) corresponding to the alarm number 41 (33). Then, processing is performed based on the processing item 43 of the corresponding abnormal event 42 (step S9).

In FIG. 3, each item of major fault and minor fault is output in a list format, and the type 31 indicating the severity of the fault, the date / time of occurrence / failure 32, the failure number 33, the failure event 34, The failure occurrence / release status 35 is listed. The failure number 33 in the list associates the CRT unit 2 with the terminal 3 (see the alarm number 41 in FIG. 4).

In FIG. 4, the cause 42 of the fault event and the action item 43 corresponding to the cause are indicated by an alarm (3
3, 41) → recognition of the cause 42 of the alarm → recognition of the action item 43 → recovery of the fault in the order of action.

In this embodiment, a field device (control device 1)
Is displayed on the screen 27 of the CRT unit 2 and output to the print 29 at the same time to notify the occurrence of an abnormal event. In response to this, the key operation of the terminal 3 (inputting the failure number 33 as the alarm number 41) causes the terminal 3 to display the cause 42 of the abnormal event and the countermeasure 43 thereof. If the countermeasure 43 is taken, the abnormal events 44 and 42 can be quickly repaired. Therefore, abnormal event 4
The repair time from the occurrence of 4, 42 to its elimination is significantly reduced. It also eliminates differences in operator proficiency,
The effect of supplementing the limits of human abilities can be expected.

[0041]

According to the monitoring apparatus for a controlled object of the present invention,
The repair time from the occurrence of an abnormal event to its resolution can be shortened, and the difference in the proficiency of the operator can be eliminated.
