Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a plant operation monitoring device suitable for monitoring the operation of a large-scale plant.

[Conventional technology]

BACKGROUND ART In order to monitor the operation of thermal power plants and nuclear power plants, it has already been put into practical use that computers are used to process information for operation and monitoring and to intensively monitor the operation.

In this case, the plant status is displayed on the display device. To operate the equipment that makes up the plant, pushbutton switches attached to the monitoring operation panel are pressed to give operating commands to the computer. Recently, a touch screen has been installed on the screen of the display device, and it is also possible to directly operate the plant using the display device by touching the plant equipment displayed on the screen and giving operation commands. It is put into practical use.

Incidentally, in order to give an operation command to a plant component device, it is usually done by two actions: selecting the device and then selecting the operation. This can be seen, for example, in JP-A-61-1
It is described in No. 6990.

[Problem to be solved by the invention]

Conventionally, the operating procedures of operators who give operating commands to plant component equipment have been fixed. Normally, operating procedures are determined from the standpoint of operational reliability during actual plant operation. However, during test runs such as periodic inspections and all-point signal tests, the same operating procedures as during actual operation must be followed, resulting in the problem that test runs take a long time. In addition, even during actual operation, especially when operating for the first time after modification, or especially when driving, it may be necessary.

The present invention has been made to address the above-mentioned problems, and its purpose is to provide a plant operation monitoring device that can perform test operations in a short time while ensuring reliability of actual operation.

Another object of the present invention is to provide a plant operation monitoring device that allows even more reliable operation by changing the operating procedure depending on the plant operation state even during actual operation.

[Means to solve the problem]

The present invention allows an operator to operate an operation input device to change the operation procedure of operation commands given to plant component equipment depending on the operating state of the plant.

Note that in this specification, the operation procedure is referred to as operation interlock strength.

[Effect]

The present invention relates to actual operation, trial operation, and periodic inspection of plants.

The operating procedure for issuing operating commands is changed depending on the plant operating status, such as during a full-point command signal test during periodic inspections.

During the test run, the operation commands and operating procedures can be simplified, so the time during the test can be shortened without compromising reliability during the actual run.

〔Example〕

FIG. 1 shows an embodiment of the present invention.

FIG. 1 shows an example in which the present invention is applied to a nuclear power plant, and FIG. 1 shows an example in which the present invention is used to monitor the operation of a condensate purification system in a nuclear power plant.

In Fig. 1, the status information of plant 1 is the process bathing power device! The data is taken into the computer 3 that performs operation monitoring via f2. The computer 3 collects and edits the status information, and outputs process status display information to the bath input device 15 (operation console) for operation monitoring via the data transmission line 4. An operator (not shown) watches the display screen of the cathode ray tube (CRT) display 7 and the lamp display state of the operation panel 15 to monitor the plant operating state. CRT display 7
For example, a plant operation monitoring screen as shown in FIG. 3 is displayed. FIG. 3 is an example of a screen for tower monitoring with screen number 103. In the case of the system diagram shown in FIG. 3, the operator performs operational operations such as opening valve FOO3A and driving the secondary pump Cool. Driving operation is CR
A touch panel 8 arranged opposite to the display surface of T7. Keyboard 9. Audio input microphone 11. This is performed by an operation input device of a push switch (not shown) attached to the operation panel 15. Driving operations using the operation input device are performed according to a predetermined operation procedure (operation interlock). The operation information input by the operator is sent to the computer 3, where operation interlock determination (operation procedure verification) is performed.

When the number of operations performed by the operator in the operation procedure is large, information is exchanged between the computer 3 and the input/output device 5 several times. When the operation interlock condition is satisfied, that is, when the operation procedure is completed, an operation command is output to the plant 1 via the process input/output device 2.

The operation procedure is as follows:
0 and is set by the operation interlock setting calculator 30.

The operation interlock depends on the type of operation terminal, its combination,
Many possibilities can be considered depending on the number of operation actions, etc.

FIG. 2 shows an example of the detailed configuration of the interlock setting computer 30 and the interlock setting input/output device [40].

In FIG. 2, the computer 30 is a central processing unit (CPU)
300. Main memory 301. It is composed of an auxiliary memory 302 and a plurality of input/output devices 303. The main memory 301 includes a program for changing interlock settings,
Tables necessary for changing settings are stored, and the auxiliary memory 302 stores a plurality of operation interlock programs. Note that the configuration of the computer 3 for operation monitoring is the same as that of the computer 30. On the other hand, the input/output device 40 is a central processing unit! (CPU) 400. Operation panel 42, CRT
44. Touch panel 45. Keyboard 46. Audio input microphone 48. It is composed of a voice input device 49 and an input/output device 50.

Next, the operation will be explained.

First, the operation for setting the operation interlock strength will be explained with reference to FIGS. 4 and 5. Note that the operation interlock can also be performed from the operation panel 42 of the input/output device [40, but CRT44. A case will be described in which the touch panel 45, keyboard 46, and microphone 48 are used.

FIG. 4(a) shows an example of an interlock setting screen displayed on the CRT 44. For example, this screen displays the keyboard 4
6 is provided with an [operation interlock setting] key, which is displayed by pressing this key. Further, this screen can also be displayed by inputting "operation interlock cerati" into the microphone 48 by voice.

The setting screen shown in FIG. 4(a) displays the content explanation of each operation interlock, the current strength (identification number of the operation interlock), the plant operation status, the settable operation interlock strength, etc.

The current strength and system operation status are stored in the main memory 301- in an interlock status management table as shown in FIG. 4(b). What are the configurable strengths?

For example, the information is that any strength of 1, 2.3 may be used when the system operating state is "command signal full point test", and that only strengths 2 and 3 are permitted during "actual operation" to prevent erroneous operation. This settable strength is also managed in the interlock setting information file as shown in FIG. 4(C).

Now, the operation interlock setting operation is performed as shown in FIG.

When the operator presses the "operation interlock setting" key by operating the keyboard 4G at step 50 ], or inputs "operation interlock cerati" into the microphone 48 at step 501B, the CRT 44
A setting screen as shown in FIG. 4(a) is displayed (step 502).

In step 503, the intensity number on the setting screen displayed on the CRT 44 is selected by touch operation 7, and in step 504, the interlock intensity is inputted into the microphone 48 by voice. In steps 505 and 506, it is determined whether voice input has been completed or touch operation has been selected. If either one has not been completed, the process returns to step 503 or 504 to execute the process. If both the touch operation selection and the voice input have been completed, the process moves to step 507, where it is determined whether the strength of the touch operation selection and the strength of the voice input match, and whether the selected strength can be set. to decide. If the intensities match and can be set, the process moves to step 508, and the CRT 44 is displayed as shown in FIG.
) to display the selected intensity and "settings" switch. If the intensity based on touch operation selection and the intensity based on voice input do not match in step 507, or if they match but cannot be set, the process moves to steps 503 and 504. After the "setting" switch is displayed in step 508, the process moves to step 509, where the operator re-determines whether the correct intensity has been selected. If it is reconfirmed in step 509 that the correct intensity has been selected, the process moves to step 510 and the "setting" switch on the screen shown in FIG. 4(a) displayed on the CRT 44 is touched. Further, in step 511, "Cerati" is voice input into the microphone 48. Next, in step 512 it is determined whether voice input has been completed, and in step 513 it is determined whether touch operation has been completed.

If both voice input and touch operation have been completed, step 51
4, the operation interlock strength is set. The operation interlock program set in this manner is transferred from the auxiliary memory 302 of the computer 30 to the memory of the computer 3.

In the flowchart shown in FIG. 5, the steps marked with an umbrella mark are operations performed by the operator, and the steps marked with an umbrella mark are decisions made by the operator.

The operation interlock is set in this way, but in practical use it is related to the safety of plant operation, so it is recommended to limit the number of operators who perform the setting operation by entering a password or ID card so that they cannot be changed easily. desirable.

Next, the operation of inputting an actual operation signal based on the operation procedure set as described above will be explained.

In order to simplify the explanation, the CRT touch operation will be explained using an example of a combination of voice operation.

Figure 6 shows the operating procedure during normal operation (interlock strength 2
) is an example of operation.

An operation monitoring screen as shown in FIG. 3 is displayed on the CRT 7 of the input/output device 5. The operator selects the symbol of the device to be operated from among the device symbols displayed on the CRT 7 by touching it on the touch panel 8 (
Step 6o1). This state is shown in bl of FIG. 9(b). The device whose device name is Fool is selected. Operation information input from the touch panel 8 is sent to the computer 3.

The computer 3 outputs display information for displaying a frame indicating that the name of the device has been selected in step 602,
Next, in step 603, the display information of the operation switch of the selected device is output, and this display information is displayed on the CRT 7. The display screen of the CRT 7 is, for example, as shown in FIG. FIG. 3 shows that the device with the device name FOO3A is selected and the "open/close" operation switches 7a and 7b are displayed.

In step 604, the operator looks at the CRT 7 and confirms whether the device displayed in a frame around the device name is the one to be selected. If the selection is incorrect, return to step 601 and try again. If the selection is correct, the process moves to step 605 and the open/close operation switch 7a displayed on the CRT 7 is pressed.
, 7b. This operating state is shown in b2 of FIG. 9(b). Touch selection information of the operation switches 7a and 7b is sent to the computer 3. The calculator 3 outputs display information for displaying the selected operation switch in different colors in step 606, and displays "
The display information of the "command" switch 7c is output, and the display information is displayed on the CRT 7. For example, the CRT7 has a third
As shown in the figure, the close operation switch 7b is displayed in a changed color (shown by hatching), and the command switch 7c is displayed.

The operator visually confirms the color change of the close operation switch 7b. If the selection of the closing operation switch 7b is incorrect, the process returns to step 605 or step 601 and the operation process is executed again. If the selection of the operation switch 7b is correct, the command switch 7C is touch-operated in step 609. This operating state is shown at b3 in FIG. 9(b). When the computer 3 receives the operation information resulting from touching the command switch 7c, it determines that the operation procedure has been completed, and in step 610 sends an operation command signal consisting of device name information and operation information via the process input input device w2. and output to plant 1.

In this way, the equipment that makes up the plant 1 is operated.
The operation will be performed three times. Normal operation is performed in this manner.

Next, the operating procedure for performing a signal all-point test will be explained with reference to FIG.

In FIG. 7, steps that perform the same processing or judgment as in FIG. 6 are given the same numbers.

In FIG. 7, after executing steps 601 to 605 that are the same as those in FIG. 6, the computer 3 determines that the operating procedure is completed by receiving the selection information of the closing operation switch 7b in step 710. and outputs a command signal. In this case, the operator's operation action is
The result will be as shown in Figure (a).

In this way, the signal all-point test is performed, and this operation procedure, which involves two operation actions in steps 601 and 605 and one judgment in step 604, is the sixth step.
Although the reliability is lower than the operating procedure shown in the figure, the operating procedure can be completed in a shorter time. The command signal all-point test involves testing hundreds to thousands of points for each operation of each device that makes up the plant, but by changing the operation interlock from 3 actions to 2 actions, the test time is significantly shortened. be able to.

Next, referring to FIG. 8, an explanation will be given of the operation procedure when the operation interlock strength is high and the operation interlock strength is high during actual operation, which requires careful operation like the first operation after modification.

In FIG. 8, steps that perform the same processing or judgment as in FIG. 6 are given the same numbers.

In FIG. 8, equipment selection in step 601, step 6
The frame display of the device name 02 is performed in the same manner as the operating procedure shown in FIG. Next, in the operating procedure of FIG. 8, without executing the display of the operating switch, which is the process of step 603 of FIG.
The operator moves from step 602 to step 604 and confirms the selected device on the screen.6 If the selection is incorrect, the operator returns to step 601 and tries again. If it is determined in step 604 that the selection is correct, the process moves to step 801, where the operator inputs the name of the selected device by voice through the microphone 11. This operation action is shown as 02 in FIG. 9(c). The computer 3 determines whether the voice-input device name sent in step 802 matches the device name selected by the touch operation. If they match, the display information of the operation switches 7a and 7b of the selected device is output and displayed on the CRT 7 (step 603).

If it is determined in step 802 that the touch selection and voice input devices do not match, a re-input request message is sent to CR.
Display it on T7. In this case, the operator re-executes the voice input process (step 801) or re-executes the touch selection operation in step 601.

In step 603, the operation switch 7 of the selected device is placed on the CRT 7.
When a and 7b are displayed, touch selection of the operation switches 7a and 7b (step 605) and color change display of the selected operation switch 7b (step 606) are performed in the same manner as in FIG. If the operator determines that the selection of the operation switch is incorrect in step 608, the operator selects the operation switch in step 605.
Return to and redo the operation switch selection. If the selected operation switch is correct, the name of the selected operation switch 7b is input by voice from the microphone 11 in step 803. This operation action is shown at 04 in FIG. 9(c). The computer 3 determines in step 804 whether the touch selection and voice input operation switch names match, and if they match, the process moves to step 607 and the command switch 7c is moved to the CRT.
7. If the operating switch names for touch selection and voice input do not match, the process returns to step 803 or 605 and is executed again. When the command switch 7c is displayed on the CRT 7, the process moves to step 805, and it is determined whether the selected device and operation are correct. If they are correct, the touch operation of the "command" switch 7c 609 (step 609) and the operation command are performed as in FIG. Signal output (step 610) is performed.

Thus, in the operating procedure of FIG. 8, step 601.8
01,605,806,6094. - In addition to the five operation actions of i and the three judgments by the operator in steps 604, 608, and 805, the computer judges twice whether the touch input and voice input match. Such an operating procedure provides an extremely safe operating interlock. In this way, highly safe operation is possible when careful operation is required, such as during repair of plant equipment or test run immediately after remodeling. Furthermore, since there is almost no risk of erroneously generating an operation command signal, the burden on the operator who tries to avoid erroneous operations can be reduced.

This is how the plant is operated,
The operation interlock strength is set depending on the operating status of the plant.

Therefore, since the number of operation actions can be set arbitrarily depending on the actual operation or the test, the time required for the test can be shortened while ensuring the reliability of the operation during the actual operation.

Next, how to change the setting of the operation interlock strength will be explained using FIG. 10.

In FIG. 10, a calculator 30 for interlock setting
interlock setting section 301 in a predetermined area of the main memory of
will be provided. The state management table 302 is shown in FIG. 4(c).
The plant operation status is stored as a status number using information sent from the computer 3 via the data transmission path 4 when the status changes. Interlock setting section 30
1 changes the setting of the operation interlock strength, that is, rewrites the strength of the state management table 302 and outputs the set strength to the computer 3 in accordance with the input information from the setting input/output device 40 by the operator. In addition, when the plant operation status changes, if the current operation interlock strength is not permitted in the intermittent operation state, the automatic setting strength is managed in the configuration information file 303 as shown in FIG. 4(b). Execute the settings change process. A plurality of operation interlock programs (
Hereinafter referred to as programs) are stored.

Further, the main memory 31 includes a program C that actually operates (hereinafter referred to as a task), a task management file that manages operation information of the task, and a task management section 33 that writes management information into the management file.

The task management unit 33 receives the setting information (strength) sent from the computer 30 and rewrites the operation interlock task management information in the task management file. Furthermore, the program stored in the auxiliary memory 32 is read out as a task to the main memory 31, and the operation interlock strength changing process is completed.

Note that since the task management information in the main memory 31 disappears when the power of the computer 3 is turned off, it is desirable to also copy it to the auxiliary memory 32 when rewriting the information.

In this way, the setting of the operation interlock strength is changed, and the operation monitoring computer 3 and the setting computer 3
Since only interlock strength information is sent and received between
The time required for transmission is shortened, and interlock setting change processing can be performed in several seconds to several seconds.

FIG. 11 shows another example of the operation interlock strength setting change process. In FIG. 11, the program for each operation interlock strength and its management information are stored in the interlock setting computer 30. The interlock setting unit 301 transmits the newly set strength program and its management information to the operation monitoring computer 3. The task management unit 33 of the operation monitoring computer 3 stores the received program in the auxiliary memory 32.
The management information of the task management files in the main memory 31 and the auxiliary memory 32 is also rewritten. Finally, the setting change process is completed by reading out the program stored in the auxiliary memory 32 as a task to the main memory 31 based on the management information.

In the example of FIG. 11, it takes several minutes to send, receive, and rewrite the program, but the auxiliary memory capacity on the operation and monitoring computer 3 side can be reduced, and auxiliary memory can be added when applying the present invention to an existing plant. Necessary (can be carried out) In addition, modifications and additions to the operation interlock program can be made using the setting computer 3o. Therefore, the operation monitoring computer 3
It has the advantage of being able to be modified or expanded without having to stop the system.

〔Effect of the invention〕

As explained above, according to the present invention, it is possible to operate the plant according to the optimal operating procedure according to the operating state of the plant.
The time required for testing can be significantly shortened while ensuring the reliability of plant operation.

In addition, in cases where special care is required, such as when operating equipment immediately after repair or modification, more operating steps are required, which allows for safer operation.

In the above embodiment, the input/output device 40 is provided for setting the operation interlock strength, but it is easily understood that the setting can be made from the operation monitoring input/output device 5. be.

In addition, although a combination of CRT touch operation and voice input operation is given as an example, operation using an operation panel.

Of course, any combination of operation actions may be used, such as operations using a keyboard, operations using a male voice, and operations using a female voice.
