Description

[Detailed description of the invention] [Purpose of the invention] (Industrial application field) The present invention relates to a plant simulator.

(Prior art) For example, plant simulators used for the purpose of training operators of industrial plans 1- such as power plants, etc., are equipped with a system that allows operators to perform response operations when a plant accident or abnormality occurs. It is equipped with a function to simulate the occurrence of such a serious accident in order to train people.

During this training, for example, an instructor who instructs the trainees inputs an operation using an instructor keyboard to cause a failure state to occur in a specific sensor.

As a result, the plant simulator sets the designated sensor in a temporary failure state, and displays an abnormality warning or the like corresponding to the sensor failure state on the simulated control panel operated by the trainee.

The operator estimated the cause of the abnormality based on the content of the abnormality warning display on the simulated control panel.

(Problem to be Solved by the Invention) In this way, in conventional plant simulators, when investigating the cause of an abnormal alarm, it is based only on the display on the simulated control panel, so it is difficult to perform response operations when an accident occurs. When training, it is difficult to carry out efficient training.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a plant simulator having a function capable of supporting training when investigating the cause of an abnormality alarm.

[Structure of the Invention] (Means for Solving the Problems) The present invention displays on a screen display device a system screen that is composed of a specified piping instrumentation diagram and a process amount display in the piping instrumentation diagram. At the same time, when a sensor symbol on the displayed system screen is selected, the state of the selected sensor is compositely displayed on the system screen, and when abnormality recovery of the sensor state is selected, the failure state of the sensor is displayed. It was designed to be restored.

(Function) Therefore, when an abnormality alarm is displayed from the simulated control panel, if you select and operate the piping instrumentation diagram where the sensor causing the abnormality is located based on the displayed content,
A system screen is displayed, and when a sensor on the system screen is selected, the status of that sensor is displayed. Thereby, the sensor causing the abnormality can be confirmed, and training for tracking down the cause of the abnormality can be conducted efficiently. Moreover, since the trainer can restore the abnormal state of the sensor, the simulated training can be continued without interruption.

(Embodiments) Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 shows a plant simulator according to an embodiment of the present invention.

In the figure, a simulated control panel 1 is used for operation by a trainee, and its operation signal Sm is applied to a plant control device model means 2.

The plant control device model means 2 simulates the operations of the auxiliary equipment, sequence control device, automatic control device, etc. of the power generation plant, and the simulation results are added to the plant dynamic characteristic model means 3 as the operating end state signal Si. It is being

The plant dynamic characteristic model means 3 simulates the plant dynamic characteristics based on the operating end state signal Si and calculates the process amount of each part of the plant, and the process amount is sent to the sensor model means 4, as a process signal Sp. And, it is added to the system screen display processing means 5.

The sensor model means 4 calculates, based on the process signal Sp, the operation of various sensors installed in various parts of the plant, the operation of the transmission system that transmits the sensor signals to each part, and the operation of the transmission system installed in the simulated control panel l. The system simulates the display signals of the various display devices and the feedback signals required by the plant control device model means 2, and the former simulation result is outputted to the sensor output screen display processing means 6 as the sensor signal Ss. The latter simulation result is the state signal Sb, S
c to the simulated control panel 1 and the plant control device model means 2, respectively.

The CRT display device 7 is for displaying on a screen the system screen display information formed by the system screen display means 5 and the sensor output display information formed by the sensor output screen display means 6. , a touch screen 8 is attached.

The touch screen 8 is used to indicate an arbitrary point on the display screen of the CRT display device 7, and the input coordinate signal Sa is transmitted to the system screen display processing means 5, the sensor output screen display processing means 6, and abnormality recovery processing means 9
are output respectively.

The system screen display processing means 5 selects a piping instrumentation diagram to be displayed interactively with the trainee based on the coordinate signal Sa input from the touch screen 8, and also selects the piping instrumentation diagram to be displayed based on the process signal Sp. A system screen is formed by synthesizing displays of prescribed process amounts, and system screen display information for displaying the system screen is formed and output to the CRT display device 7. Further, the system screen display processing means 5 outputs the identification information Id of the piping instrumentation diagram selected at that time to the sensor output screen display processing means 6 and the abnormality recovery processing means 9.

The sensor output screen display processing means 6 includes a touch screen 8
Check whether the coordinate signal Sa output from Based on the applied sensor signal Ss, sensor display information for displaying a sensor display screen that displays the state of the selected sensor in a fixed format near the sensor symbol is formed, and the sensor display information is displayed on the CR7 display device 7. Output.

The abnormality recovery processing means 9 causes the coordinate signal Sa output from the touch screen 8 to be activated when the abnormality recovery button on the sensor display screen is displayed near any sensor symbol on the piping and instrumentation diagram corresponding to the identification information Id. Check whether the coordinates match or not. If they match, the identification information Is of the sensor corresponding to the matched abnormality recovery button is output to the sensor model means 4 and the instrument failure simulating means 12.

The instructor keyboard 10 is used to operate and input sensor failure information sb consisting of identification information for temporarily setting a sensor in a failure state and data on the failure state. It is added to the failure simulating means 11 and the instrument failure simulating means 12.

The sensor failure simulating means 11 forms a sensor failure signal Bb corresponding to the sensor failure information Os, and the sensor failure signal Bb is added to the sensor model means 4.

The instrument failure simulating means 12 determines various indicators, recorders, and 91 machines (annunciators) to be set to abnormal states in the simulated control panel 1 in response to the sensor failure information Bs, and based on the determination results. It forms instrument failure information Bk for setting them in a failure state, and the instrument failure information 8 is output to the simulated control panel l. Further, when the identification information Is is input, the output contents of the meter failure information Bk corresponding thereto are cleared.

When the sensor failure signal Bb is input, the sensor model means 4 changes the state of the sensor specified by the sensor failure signal Bb to the specified failure state, and changes the content of the corresponding sensor signal Ss to the changed state. Set to .

The simulated control panel 1 normally displays the contents of various instruments that indicate the status of each part of the plant based on the status signal sb input from the sensor model means 4, and displays instrument failure information Bk.
When inputting , the display contents of the meter specified by the meter failure information Bk are changed based on the contents of the meter failure information Bk.

FIG. 2 shows an example of processing by the sensor failure simulating means 11.

The sensor failure simulating means 11 inputs operation information from the instructor keyboard 10 (process 101), and when a failure request is being operated (result of judgment 102 is YES).
, according to the contents of the operation information, forms a sensor failure signal Bb in which the specified sensor type and numerical value are set, and outputs it to the sensor model means 4 (process 1
03).

With the above configuration, the plant control device model means 2 and the plant dynamic characteristic model means 3 are always operated based on the operation signal Ss corresponding to the operation content of the simulated control panel l and the status signal Sc output from the sensor model means 4. simulates the plant, and as a result, the status of each part of the plant is displayed on various indicators provided in the simulation control panel 1 based on the status signal sb output from the sensor model means 4.

Here, when the instructor inputs the identification information of the sensor to be set to a failure state and the failure information from the instructor keyboard IO, the sensor failure information 8s corresponding to the operation input will be displayed in the prosthetic arm group 11 and the instrument failure simulation. It is output to means 12.

As a result, the instrument failure simulating means 12 outputs the instrument failure information B corresponding to the sensor designated as being in the failure state at that time.
k is output to the simulated control panel 1, thereby causing the display content of the corresponding display on the simulated control panel l to become abnormal.

On the other hand, the sensor failure signal Bb corresponding to the operation content is output from the sensor failure simulating means 11, and the content corresponding to the designated sensor among the sensor signals Ss output from the sensor model means 4 is the sensor failure signal Bb. The content will be changed to .

Now, the trainee who saw the display of the abnormal condition on the simulated control panel 1,
The cause of the abnormality is estimated based on the displayed content, and a piping instrumentation diagram corresponding to the arrangement of the sensor considered to be the cause of the abnormality is interactively selected using the CRT display device 7 and the touch screen 8.

Thereby, the system screen display processing means 5 displays, for example, a system screen 200 as shown in FIG. 3(a) on the CRT display device 7 in response to the selection operation.

In this system screen 200, symbols 201, 202
203 each indicates a sensor, and symbol 204
, 205 indicate pumps, symbols 206 indicate valves, and other lines indicate piping. Furthermore, the display sections 207 and 208 display process quantities corresponding to the gauge displays disposed at corresponding positions.

Looking at such a system screen 200, the trainee touches the sensor symbol 202 and 203 of the sensor estimated to be the cause of the abnormality.

As a result, the touch screen 8 outputs a coordinate signal Sa indicating the coordinates of the touched position.

The sensor output screen display processing means 6 determines that the sensor symbols 202 and 203 have been touched, and displays the contents of the sensor signals Ss of the sensors corresponding to the respective sensor symbols 202 and 203 as shown in FIG. 3(b). Display screen 2
Display as 10,211.

At this time, the sensor signal Ss has been changed to a value corresponding to the sensor failure signal Bb, and the set abnormal values are displayed on the display screens 210 and 211, respectively.

In this case, the display content of the display screen 210 is 0.0ATG, while the display content of the 1 display section 208 is 40.0ATG.
Since the sensor symbol 202 is different from the sensor Px1-□, it is confirmed that the sensor Px1-□ of the sensor symbol 202 is abnormal.

Also, on the display screen 211, the sensor ps knee is 60A.
It is displayed that it is turned on when the TG is exceeded and that it is currently on. On the other hand, the display content on the display unit 208 is 40,0 ATG, which is the sensor ps1-0
is the value that should be in the off state under normal conditions. From the above, it is confirmed that the sensor ps is abnormal.

The trainer who has confirmed the cause of the abnormality in this way touches the abnormality recovery buttons 212 and 213 added to the display screens 210 and 211, respectively.

As a result, the touch screen 8 outputs a coordinate signal Sa indicating the coordinates of the touched position.

The abnormality recovery processing means 9 each have an abnormality recovery button 212.
, 213 is touched, and as a result, abnormality recovery is commanded to sensor Px knee 1. psi-0 is notified to the sensor model means 4 and the instrument failure simulating means 12 using the identification information Is.

As a result, the sensor model means 4 restores the content corresponding to the identification information Is of the content of the sensor signal Ss that was set to the abnormal state to the original state.

Further, the instrument failure simulating means 12 cancels the failure state of the equipment related to the sensor corresponding to the identification information Is among the devices set in the failure state by the instrument failure information Bk.

As a result, among the devices that were displayed as abnormal on the simulated control panel 1, the abnormal display of the device related to the sensor whose abnormality was restored by the trainer is restored to normal.

In this way, training for investigating the cause when an abnormality occurs can be carried out extremely efficiently.

In the above-described embodiment, a touch screen is used as a pointing device for indicating coordinates on the screen of a CRT display device, but other devices such as a mouse can be used as the pointing device.

[Effects of the Invention] As described above, according to the present invention, a system screen formed by combining a designated piping instrumentation diagram and a process amount display in the piping instrumentation diagram is displayed on the screen display device, and When a sensor symbol on the displayed system screen is selected, the state of the selected sensor is displayed in combination on the system screen, and when abnormal sensor state recovery is selected, the failure state of that sensor is restored. Now, when an abnormality alarm is displayed from the simulated control panel, if you select and operate the piping and instrumentation diagram where the sensor causing the abnormality is located based on the display contents, the system screen will be displayed. If you select a sensor in that system screen, the status of that sensor will be displayed. Thereby, the sensor causing the abnormality can be confirmed, and training for tracking down the cause of the abnormality can be conducted efficiently. Furthermore, since the trainer can restore the abnormal state of the sensor, the simulation training can be continued without interruption.
