Description

The present invention relates to a plant operation monitoring apparatus suitable for performing operation monitoring of a large plant.

[Conventional technology]

It has already been put into practical use that centralized operation monitoring is performed by performing information processing for operation and monitoring using a computer to monitor the operation of a thermal power plant or a nuclear power plant. In this case, the plant status is displayed on the display device. In order to operate the equipment that constitutes the plant, a push button switch attached to the monitoring operation panel is pressed to give an operation command to the computer. In addition, recently, a touch screen is mounted on the screen of the display device, the plant equipment displayed on the screen is touched from the touch screen to give an operation command, and the plant can be directly operated using the display device. It is used in practice.

By the way, in order to give an operation command to the plant component equipment, there is a two-action method in which a normal equipment is selected and then an operation is selected. This is described in, for example, Japanese Patent Laid-Open No. 61-16.
It is described in Japanese Patent No. 9907.

[Problems to be Solved by the Invention]

Conventionally, the operation procedure of an operator who gives an operation command to a plant component has been fixed. Normally, the operating procedure is determined from the viewpoint of the reliability of operation during actual plant operation. However, it is necessary to adopt the same operation procedure as in actual operation during test operation such as periodic inspection and all-signal test.
There is a problem that the test operation takes a long time. Also,
Even in actual operation, particularly careful operation may be required during initial operation after modification.

The present invention has been made in consideration of the above points, and an object of the present invention is to provide a plant operation monitoring device capable of performing a test operation in a short time while ensuring the reliability of an actual operation.

[Means for solving the problem]

According to the present invention, an operator operates the operation input device to input an operation command to be given to the plant component equipment during the plant test less than during the actual plant operation.

In the present specification, the operation procedure is referred to as the operation interlock strength.

[Action]

According to the present invention, the operation procedure for giving an operation command is changed according to the plant operating state such as the actual operation of the plant, the trial operation, the periodic inspection, and the command signal all-point test in the periodic inspection. Since the operation procedure for giving the operation command during the test operation can be simplified, the time during the test can be shortened without impairing the reliability during the actual operation.

〔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 one for operating and monitoring an ascites purification device of a nuclear power plant.

In FIG. 1, the state information of the plant 1 is taken in via a process input / output device 2 to a computer 3 that monitors operation. The computer 3 collects and edits the status information and outputs the process status display information to the operation monitoring input / output device 5 (operation console) via the data transmission path 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 operation state. On the 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 monitoring one tower of screen number 103.
In the case of the system diagram shown in FIG. 3, the operator may use, for example, the valve F0.
Open 03A, and then drive the pump C001. Touch panel 8, keyboard 9, voice input microphone 11, which is placed facing the display surface of CRT 7,
This is performed by an operation input device of a push switch (not shown) attached to the operation panel 15. The driving operation by the operation input device is performed according to a predetermined operation procedure (operation interlock). The operation information input by the operator is sent to the computer 3 to perform operation interlock determination (operation procedure verification). When the number of operation actions of 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, the operation command is output to the plant 1 via the process input / output device 2. The operation procedure is set by the input / output device 40 for setting the operation interlock and the computer 30 for setting the operation interlock.

Many operation interlocks can be considered depending on the type of operation terminal, the combination thereof, the number of operation actions, and the like.

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

In FIG. 2, a computer 30 is a central processing unit (CPU) 30.
0, main memory 301, auxiliary memory 302 and a plurality of input / output devices 3
Composed of 03. The main memory 301 stores a program for changing interlock settings and tables necessary for changing the settings, and the auxiliary memory 302 stores a plurality of operation interlock programs. The computer 3 for operation monitoring has the same configuration as the computer 30. On the other hand, the input / output device 40 comprises a central processing unit (CPU) 400, an operation panel 42, a CRT 44, a touch panel 45, a keyboard 46, a voice input microphone 48, a voice input device 49 and an input / output device 50.

 Next, the operation will be described.

First, the operation of setting the operation interlock strength
This will be described with reference to FIGS. The operation interlock can also be performed from the operation panel 42 of the I / O device 40, but
A case where the operation is performed by using T44, touch panel 45, keyboard 46 and microphone 48 will be described.

FIG. 4 (a) shows an example of the interlock setting screen displayed on the CRT 44. This screen is displayed, for example, by providing a “operation interlock setting” key on the keyboard 46 and pressing this key. Also, this screen is a microphone
It can also be displayed by voice inputting "operation interlock setting" on 48.

On the setting screen shown in FIG. 4 (a), the contents of each operation interlock, the current strength (identification number of the operation interlock), the plant operating state, the settable operation interlock strength, etc. are displayed. The current strength and system operation status are stored in the interlock status management table in the main memory 301 as shown in FIG. The settable strength means, for example, when the system operation status is "command signal all-point test", any strength of 1, 2, and 3 may be used, and at the time of "actual operation", only a few strengths can be used to prevent erroneous operation. Is the information that permits. This settable intensity is also shown in Fig. 4 (b).
It is managed by the interlock setting information file like.

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

When the operator operates the keyboard 46 at step 501A and presses the "operation interlock setting" key or inputs the voice "operation interlock setting" into the microphone 48 at step 501B, the CRT 44 is shown in FIG. A setting screen as shown in a) is displayed (step 502). At step 503, select the strength number on the setting screen displayed on the CRT 44 by touch operation, and at step 504 select the microphone 48
Input the interlock strength by voice. Step 505,
At 506, it is determined whether the voice input has been completed or the touch operation has been selected. If either one is not completed, the process returns to step 503 or 504 to execute the processing. If both the touch operation selection and the voice input are completed, the process proceeds to step 507, it is judged whether the strength by the touch operation selection and the strength by the voice input match, and whether the selected strength can be set. To judge. If the intensities match, and if they can be set, the flow advances to step 508 to display the selected intensity and the "set" switch on the CRT 44 as shown in FIG. 4 (a). In step 507, when the strength by touch operation selection and the strength by voice input do not match, or even if they match, but cannot be set, the processing proceeds to steps 503 and 504. After displaying the "set" switch in step 508, the operator moves to step 509 and the operator re-determines whether the correct intensity has been selected. If you reconfirm that you selected the correct strength in step 509, move to step 510 C
Touch the "Set" switch on the screen shown in Fig. 4 (a) displayed on the RT44. Further, in step 511, the voice "SETTING" is input to the microphone 48. Then, 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. When both the voice input and the touch operation are completed, the operation interlock strength is set in step 514. The operation interlock program set in this way is stored in the auxiliary memory 30 of the computer 30.
2 is transferred to the memory of the computer 3.

The steps marked with * in the flow chart shown in FIG. 5 are the operation actions of the investigator, and the steps marked with ** are for the operator to judge.

In this way, the operation interlock is set, but since it is related to the safety of plant operation in practical use, it is necessary to limit the operator who performs the setting operation by entering the password or ID card so that it cannot be changed easily. desirable.

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

In order to simplify the description, an example of a combination of CRT touch operation and voice operation will be described.

FIG. 6 shows an example in which the operation is performed according to the operation procedure (interlock strength 2) during normal 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 among the device symbols displayed on the CRT 7 by touching the touch panel 8 (step).
601). This state is shown by b1 in FIG. 9 (b). A device with the device name F001 is selected. The 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 device name has been selected in step 602, and then step 3
The display information of the operation switch of the device selected in 603 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. In Fig. 3, the device with the device name F003A is selected, and the operation switch for "Open / Close" 7
Indicates that a and 7b are displayed.

The operator looks at the CRT 7 at step 604 and confirms whether the device indicated by a frame in the device name is to be selected. If the selection is incorrect, return to step 601 and try again. If the selection is correct, move to step 605, CRT7
Select one of the open and close operation switches 7a and 7b displayed in. This operation state is indicated by b2 in FIG. 9 (b).
Shown in The touch selection information of the operation switches 7a and 7b is sent to the computer 3. The computer 3 outputs the display information for color-changing the operation switch selected in step 606, outputs the display information of the "command" switch 7c in step 607, and causes the CRT 7 to display these display information. CR
At T7, for example, as shown in FIG. 3, a closing operation switch 7b is color-changed and displayed (hatched), and a command switch 7c is displayed. The operator visually confirms the color change of the closing switch 7b. If the closing switch 7b is selected incorrectly, 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, in step 609 the command switch 7c is touch-operated. This operation state is shown by b3 in FIG. 9 (b). When the computer 3 receives the operation information due to the touch of the command switch 7c, the computer 3 determines that the operation procedure is completed, and the step 610 is executed.
In step 1, an operation command signal including device name information and operation information is output to the plant 1 via the process input / output device 2.

In this way, the devices that make up the plant 1 are operated, but the operator performs the operation action three times at steps 601, 605, and 609. Normal operation is performed in this way.

Next, an operation procedure for performing the signal all-point test will be described with reference to FIG.

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

In FIG. 7, when the same procedure and the same processing as in FIG.
At 0, it is determined that the operation procedure is completed by receiving the selection information of the closing operation switch 7b, and the command signal is output. The operation action of the operator in this case is shown in FIG. 9 (a).
become that way.

In this way, the signal all-point test is carried out. The two operation operations at steps 601, 605 and step 6 are performed.
This operation procedure for making one judgment in 04 is less reliable than the operation procedure in FIG. 6, but can complete the operation procedure in a short time. In the command signal all-point test, hundreds to thousands of points are tested for each operation of each device that constitutes the plant. By changing the operation interlock from 3 actions to 2 actions, the test time is significantly reduced. can do.

Next, the operation procedure when the actual operation requires careful operation like the first operation after modification and the operation interlock strength is high will be described with reference to FIG.

In FIG. 8, steps that carry out the same processes or judgments as in FIG. 6 are given the same numbers.

In FIG. 8, device selection of step 601 and step 602
The frame display of the device name of is performed in the same manner as the operation procedure of FIG. Next, in the operation procedure of FIG. 8, step 603 of FIG.
The operator shifts from step 602 to step 604 and confirms the selected device on the screen without executing the display of the operation switch, which is the process of (1). If the selection is incorrect, the process returns to step 601 and the process is performed again. If it is determined that the selection is correct in step 604, the process proceeds to step 801, and the operator inputs the name of the selected device by voice from the microphone 11. This operation action is shown as c2 in FIG. 9 (c). Computer 3 step
The device name of the voice input sent in 802,
It is determined whether the device name selected by the touch operation matches. 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). When it is determined in step 802 that the touch selection device and the voice input device do not match, a re-input request message is displayed on the CRT 7. At this time, the operator re-executes the voice input process (step 801), or re-executes from the touch selection operation of step 601.

When the operation switches 7a and 7b of the selected device are displayed on the CRT 7 at step 603, the touch selection of the operation switches 7a and 7b (step 605) and the color change display of the selected operation switch 7b (step 606) are shown in FIG. The same is done as in the case of. If the operator determines in step 608 that the selection of the operation switch is incorrect, the operator returns to step 605 and performs the operation switch selection again. If the selected operation switch is correct, change the name of the operation switch 7b selected in step 803 to MIC 1
Input voice from 1. This operation action is shown as c4 in FIG. 9 (c). In step 804, the computer 3 determines whether or not the touch switch selection and voice input operation switch names match, and if they match, the process moves to step 607 and the command switch 7c is displayed on the CRT 7. If the touch switch selection and voice input operation switch names 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, move to step 805, judge whether the selected device and operation are correct, and if it is correct, touch operation (step 609) and operation command of the "command" switch 7c of 609 as in FIG. A signal is output (step 610).

Thus, in the operation procedure of FIG. 8, steps 601, 801,
In addition to the five operation actions at 605, 806, and 609, and the operator's determination at steps 604, 608, and 805 three times, the computer determines that touch input and voice input match twice. Such an operating procedure is a highly safe operating interlock. In this way, highly safe operation is possible when careful operation is required, such as when repairing plant equipment or performing trial operation immediately after modification. Further, since there is almost no risk of erroneously generating the operation command signal, it is possible to reduce the burden on the operator who tries to avoid the erroneous operation.

The operation of the plant is performed in this manner, and the operation interlock strength is set according to the operating state of the plant. Therefore, the number of operation actions can be arbitrarily set depending on the actual operation or the test, so that the time 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 described with reference to FIG.

In FIG. 10, an interlock setting unit 301 is provided in a predetermined area of the main memory of the interlock setting computer 30. The state management table 302 is as shown in FIG. 4C, and the plant operating state stores information sent from the computer 3 via the data transmission path 4 as a state number when the state changes. The interlock setting unit 301 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 according to the input information from the setting input / output device 40 by the operator. Further, when the plant operation state changes and the current operation interlock strength is not permitted in the new operation state, the setting information file 30 is displayed as shown in FIG. 4 (b).
Execute the setting change processing to the automatic setting strength managed in 3. A plurality of operation interlock programs (hereinafter referred to as programs) are stored in the auxiliary memory 32 of the operation monitoring computer 3. Further, the main memory 31 has a task management file that manages a program (hereinafter, referred to as a task) that actually operates, operation information of the task, and a task management unit 33 that writes management information in 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 of the task management file. Further, the program stored in the auxiliary memory 32 is read as a task into the main memory 31, and the operation interlock strength changing process is completed. Since the task management information in the main memory 31 is lost when the computer 3 is turned off, it is desirable to copy it in the auxiliary memory 32 when rewriting.

In this way, the setting of the operation interlock strength is changed. The operation monitoring computer 3 and the setting computer 30
Since only interlock strength information is sent and received between
The time relating to transmission is shortened, and the interlock setting change processing can be performed in a few seconds to a few tens of seconds.

FIG. 11 shows another example of the setting change process of the operation interlock strength. In FIG. 11, the program for each operation interlock strength and its management information are held in the interlock setting computer 30. Interlock setting section 301
Transmits the program of the new set strength 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,
Further, the management information of the task management files in the main memory 31 and the auxiliary memory 32 is rewritten. Finally, the setting change process is completed by reading the program stored in the auxiliary memory 32 as a task into the main memory 31 based on the management information.

In the example of FIG. 11, it takes several minutes to send and receive and rewrite the program, but the auxiliary memory capacity on the side of the operation monitoring computer 3 can be reduced, and an auxiliary memory is added when the present invention is applied to an existing plant. Can be implemented without need. Further, the setting computer 30 can also be used to modify or expand the operation interlock program. Therefore, there is an advantage that the operation monitoring computer 3 can be modified or added without stopping.

〔The invention's effect〕

As described above, according to the present invention, since the operation can be performed in the optimum operation procedure according to the plant operation state, it is possible to significantly reduce the time required for the test while ensuring the reliability of the plant operation. it can. Also, equipment repair,
If you need to be very careful, such as when you are driving immediately after remodeling, you can perform a safer operation because the operating procedure is increased.

Although the input / output device 40 for setting the operation interlock strength is provided in the above-described embodiment, it is easily understood that the input / output device 40 for operation monitoring can be used for setting. .

Also, the combination of touch operation and voice input operation of CRT is taken as an example, but any combination of operation actions such as operation by operation panel, operation by keyboard, operation by male voice and female voice is possible. Of course it's good.
