Abstract

PURPOSE: To easily analyze training operation procedures by displaying contents of trainee's operation and an alarm state simultaneously with a process variable. CONSTITUTION: A plant system diagram is displayed on a CRT display device 1 with a touch screen 1a, and an apparatus can be operated when the trainee touches this apparatus displayed in this diagram. An operation contents input part 2 inputs contents of the operation from the screen 1a to an operation control part 3, and this control part 3 takes in simulation contents from a simulation contents storage part 4 based on these operation contents to perform the simulation operation and compares the process variable obtained from the operation result with a limit value taken out from the storage part 4 to discriminate whether an alarm state is set or not or the like. These process variable, operation contents, and alarm state are displayed on the display device 1 by a simulation result output part 5, thus facilitating analysis of training operation procedures.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a simple operation training simulator device suitable for later analyzing operation details during plant simulation operation training.

(Prior Art) In recent plant operation training, it is often desired to use a so-called simple operation training simulator device that uses a CRT display with a touch screen instead of using a simulated control panel similar to the actual one. In this simplified driving training simulator device, a desired plant system diagram, etc., is displayed on the CRT display 1 with a lattice screen by operating a selection button. Therefore, for example, by touching the equipment in the plant system diagram displayed there, it is possible to turn the plant equipment 0N10FF in the same way as giving a command from the control panel, and plant operation training becomes possible.

In this way, the simple operation training simulator device has a major feature in that even beginners can freely study plant operation training on their own without using a large control panel.

(Problems to be Solved by the Invention) However, in the conventional simple operation training simulator device as described above, only the plant state can be reproduced after the trainee performs his own operation training. For this reason, it has been extremely difficult to judge whether the plant operation is good or bad based on the state of the plant, and to learn about these problems and use them to improve the operation.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a simple driving training simulator that allows a trainee to easily grasp problems in driving operation after training alone.

[Structure of the Invention] (Means for Solving the Problems) The present invention stores and stores major process quantities registered in advance during operation in chronological order, and at the same time The operation details such as the operating terminal number, time, and status as well as the alarm content such as the alarm number, occurrence time, and status that occurred at that time are also stored in memory, and after the training is completed, the memorized process quantities are displayed in a graph and the By touching the graph, the contents of the operation and the contents of the alarm at that time are displayed.

(Function) By doing the above, the trainee can reproduce the main process quantities on a graphical display after the training is completed.

By touching the desired position on the graph H, you can see how the operation is being performed when the process amount is changing, and how the alarm status has changed accordingly. Operational problems can be easily identified.

(Embodiment) FIG. 1 shows a block configuration diagram of a simple driving training simulator according to an embodiment of the present invention, in which a CR7 display 1 with a touch screen 1a is shown.

A plant system diagram is displayed, and by touching the equipment displayed there, the trainee can operate the equipment.

The operation content input unit 2 is a part that inputs the content of an operation from the touch screen 1a of the CR7 display 1 to the arithmetic control unit 3.

The arithmetic control unit 3 takes in simulated content from the simulated content storage unit 4 based on the operation content and performs a simulated calculation, and also processes the amount of process obtained from this simulated calculation result and limits taken out from the simulated content storage unit 4. This is the part that compares the values with the values to determine whether there is an alarm state or not.

The simulated content storage unit 4 includes a table showing each operating terminal name corresponding to each operating terminal number which is the operation content, and
A table etc. showing each alarm name corresponding to each alarm number which is the alarm content is also stored.

The simulation result output section 5 is a section that outputs the process amount, operation details, and alarm state to the touch screen CR7 display 1.

As shown in FIG. 2, the training record commanding device 6 has an operation section including a start key 61 . It includes a stop key 62 for stopping recording and a display key 63 for displaying the recording.

The start key 61 instructs the arithmetic control unit 3 to input operation details, alarm status,
Then, a save command is outputted to cause the process quantities to be saved in each storage unit as a training record in chronological order. The stop key 62 outputs a stop command to stop the storage operation as a record of regular training. The display key 63 outputs a display command to output the training record data stored in each storage section to the CR7 display 1.

Upon receiving the training record start command from the training record command device 6, the process quantity storage unit 7 stores information about the various process quantities calculated by the calculation control unit 3 through simulation calculations, which have been set in advance through the touch screen 1a. A predetermined process amount is stored every 61 hours.

Upon receiving a training recording start command from the training recording command device 6, the alarm content storage unit 8 stores an alarm number representing the content of the alarm and the time of occurrence of the alarm when the arithmetic control unit 3 determines that an alarm state exists. and its occurrence state (for example, 1T' when it occurs, "0" when it is released) are stored as a - set in the order of occurrence.

The operation content storage unit 9 receives a training recording start command from the training recording command device 6 to display the touch screen la.
Contents of operation operations performed on the attached CRT display 1, including an operation number, operation time, and state (for example, 11111 when the water pump starts, 02 when it stops, etc.) are stored in the order of occurrence. It is.

Next, the operation of this embodiment with the above configuration will be explained with reference to the flowcharts shown in FIGS. 3 and 4.

Here, the calculation control unit 3 includes a counter "5IGN" for determining the command from the training record command device 6.

A counter "'oc" for storing operation contents in the operation contents storage section 9, a counter "AC" for storing the alarm state in the alarm contents storage section 8, and a counter "AC" for storing the process amount in the process interrupt storage section 7. Counter 1 (p cIt
, and displayed the operation details and warning details as training records. Counter di Q D to determine whether
#j is prepared to control the storage of various data.

The arithmetic control unit 3 sets the counter “5IGN” for determining the command from the training record control device α6 to O, and performs processing 1.
01) Waiting for commands from the training record command device 6During the execution of simulated plant operation, the trainer records the training record when he or she wants to reproduce the operation contents, alarm contents, and process quantities for post-operation training evaluation. Operate the operation keys of the command device 6. However, if you think that there is no need to do so, of course you do not need to operate the upper key of the training record command device 6.

If no commands are received from the training record command device 6, the determination processes 102, 103, and 104 are passed with NO. Also, at this time, since 5IGN=O, determination process 10
5 also passes with NO, the arithmetic control unit 3 performs a simulated operation according to the operation content input from the CRT display 1 with touch screen LA via the operation content input unit 2, and outputs the result to the simulation result output unit 5. The output is displayed on the CRT display 1. At the same time, the calculated various process quantities are stored and saved in the memory within the arithmetic control section 3. Also, at this time, it is determined whether there is an alarm state according to the process amount, and whether the alarm window is turned on or off is also determined (10[1i). Next, 1 judgment process 107 is passed with NO, and l-, (108
), the process returns to process 102 and enters the next process cycle.

Normally, by repeating the above processing, various process quantities calculated by performing simulated calculations every ΔT time are displayed on the CR7 display 1 as necessary, and the memory ( RAM).

The calculation control unit 3, while executing such simulated calculation processing,
When a training person receives a recording start command from the training recording command device 6 by operating the start key 61 of the recording command device 6 in order to save a record, the determination process 102 is passed with YES. Processing to cancel the start command is performed (10!11). This is a process for stopping the start command since once the trainer presses the start key 61 of the training record command device 6, the start command will not be issued. Next, the contents of the counters QC, 00, AC, and PC are set to 0 (110), and 5IGN is set to 1 (111). In addition, the judgment process 105 is passed with No, a simulated calculation is performed according to the operation content, and the result is output to the CIIT display 1 and is stored in the memory in the calculation control unit 3 (106). At this time, 5IGN=1 Therefore, the judgment process 107 is passed with '/ES, and the operation content inputted from the CRT display device 1 with touch screen 1 through the operation content input section 2, that is, the trainee The number of the operating end operated from the display 1, the time at that time, and the operation status (ONloFF, open/closed, etc.) are stored in the OC address of the storage area of the operation content storage unit 9, and the next operation content is saved. In preparation for this, the address is incremented by one (112). Furthermore, if an alarm state occurs as a result of executing the process 106, the content of the alarm, that is! 1 alarm number, time, and status (distinction between occurrence and stop) are stored in the maintenance rear AC of the alarm content storage unit 8, and +1 is added to AC (11
3) Furthermore, among the process quantities obtained by executing the process 106, a preset process quantity is stored in the storage area pc of the process quantity storage unit 7, and pc+t is performed (11
4).

Next, after ΔT has elapsed (108), when entering the next processing cycle, 1 judgment processing 102, 103, 104, 105 is passed with No, and after processing 106 is executed again, 1 judgment processing 107
is passed with YES, and processes 112 to 114 are executed.

In this way, when the start key 61 of the training record command device 6 is pressed, the predetermined process quantities, alarm contents, and operation contents that are to be reproduced later are stored in the process quantity storage section 7. The alarm content storage unit 8 and the operation content storage unit 9 store the same period of ΔT.

When a stop command is input from the training record command device 6 to the arithmetic control unit 3 by operating the stop key 62 of the training record command device 6 in order to stop recording storage, the trainee executes the 1 determination process 102. If No, the determination process 103 after passing is YE.
S, and the stop command is canceled for the same reason as in the case of the previous start command (115). Then, in order to store the stop command following the start command, set 5IGN=2 (116.1
11) In this case, if a stop command is input without a start command, the determination process 116 determines that nothing is done to invalidate the stop command. Next, determination process 10
5 with NO, and after executing processing such as a simulated calculation in process 106, exit with determination process 107 with NO, and proceed to process 112-11.
Bypass 4.

In this way, the trainer uses a CRT with a touch screen LA.
Plant simulation training is in progress through display 1.

For example, it is difficult to respond to changes in plant status,
When you feel like reproducing the training, use the training record command device i'j6.
Operate the start key 61 to set the process amount at that time, ¥1
Save information status and operation details. Further, when the plant condition has stabilized and there is no longer a need for reproduction, the save is stopped by operating the stop key 62 of the training record commanding device 6. Next, in order to reproduce it, the display key 63 of the training record command device 6 is operated.

As a result, when a display command is input from the training record command device 6, the arithmetic control unit 3 selects No.
After passing the 1 judgment process 104 with YES, the display command is canceled (118), and in order to remember that the display command was input after the stop command, 5IGN is set to 3 (119, 210). In this case, if the step of starting and stopping line recording is not completed, do nothing to invalidate the 1 display command (119ON No), and if the step of starting and stopping line recording is completed, the command counter is "5IGN". is 2 (YES at 119), and at this time, the command counter "5IGN" is set to 3 to indicate that the display command has been received.
(120), and as a result, the process 105 is passed with YES, and a subroutine for displaying the training record as shown in □ shown in FIG. 4 is executed (121).

When entering the display processing subroutine shown in FIG. 4, 5IGN=3, so the determination processing 122 is
ES, the process amount Pv for one hour from the start of training recording is retrieved from the process amount storage section 7, and the screen shown in the CRTR 7 display tube 5 is displayed via the simulated result output section 5 (123). At this time, an operation display area ^, an alarm display area B, and a graph update button C are displayed on both sides of the CR7 display 1 as shown in the figure.

Next, to remember that the curve display of the process amount has been completed, set 5IGN = 4 (124), and on the other hand, set the counter OD to 0 to indicate that the operation contents and alarm contents have not been displayed yet. (125), the training record display processing 121 which is a subroutine is ended, and 3
After 10 minutes, the next processing cycle begins.

In the next processing cycle, 5 judgment processes 102 to 104 are executed as N011.
Pass 05 with YES and enter process 121. Since the process amount recorded during training is already displayed in a graph on CR7 display 1, pass 4th judgment process 122 with NO and enter operation details. Touch screen via part 2
Input the operation details from CRT display 1 with a (12G
).

That is, the trainee sees the screen display shown in FIG. 5 displayed on the CR7 display 1, and if he/she wants to see a graph display of the process amount beyond that, he/she touches the graph update button C from the touch screen 1al-. do. If you want to know the details of the operation and warnings before and after time 12, touch the position corresponding to time 11 on the displayed curve.

As a result, in the determination process 127, it is determined whether the touched location is the C position or the 0 position on both sides, and the operation details at the D position are determined.
In the case of a request to display alarm contents (YES in 127), the operation contents within the time period (Tyu±Δtz) and the alarm contents are retrieved from the operation contents storage section 9 and the alarm contents storage section 8, respectively, and the simulated result output section 5 to CRTR7 display tube 6pi
A display is output as shown in il (128).

Also, a * mark is displayed on the touched D position, and
Similar to the display of the operation update button E for updating the display of the part that cannot be displayed in the operation display area A, the alarm update button F for updating the display of the alarm display area B is displayed (129), and then, With OD as 1 (130),
The display processing subroutine 121 ends.

On the other hand, if the touched location on both sides of the CR7 display 1 is the graph update button C position, after passing the 1 judgment process 127 with No, the judgment process 131 becomes YES, and the 5IGN is +
1 (132). Then, the process quantities for the next seven hours are taken out from the process quantity storage section 7 and displayed as a new graph on both sides of the CRT display 10 in place of the process graph display that has been displayed so far (133).

By the way, the determination process 131 is passed with YES after passing the process 124, and 5IGN=4 is set for the first time. When this passes through the process 132, 5IGN
= 5, and in process 133 T X (SIGN-4)
= T.

The process amount for the next seven hours will be taken out from the address point T in the process amount storage section 7.

That is, the process quantity to be displayed in a graph is initially displayed from address points 0 to T in the process quantity storage section 7, and secondly from address points T.
From the address point ~2T, the third time from the address point 2T ~ 3rd, and so on, each time the graph is updated, one hour is taken out.

Next, when updating the graph, be sure to set the OD to 20 (1
34) The display processing subroutine 121 is ended.

By the way, as mentioned above, when the touch position on the screen of the CIIIT display 1 is the D position in Fig. 5, the screen display shown in Fig. 6 is displayed. When the Kan IJeJ member touches the operation update button E, the determination process 135.136 becomes Y in the next display processing cycle.
IES, and if the operation contents are not fully displayed in the display area A and are still in the operation contents storage section 9, the next operation contents are retrieved and displayed in place of the currently displayed display contents (
137), On the other hand, if the trainer touches the alarm update button F,
After passing the determination process 138 with YES, the next alarm content is fetched from the alarm content storage unit 8 and the display of the operation content is updated.C
The updated display is displayed on the RT display 1 (13).

In this way, the trainee presses the start key 61 of the training record command device 6 when he or she wishes to reproduce the plant operating state later during the training, and then presses the stop key 62 when it is no longer necessary to do so. When the stop key 62 is pressed after the training is completed, the process amount recorded during the training is displayed as a curve on the screen of the CRT display 1, as shown in FIG. The trainee looks at this double-sided display, and if he or she wants to see the future state of the plant, he or she touches the graph update button C one after another. Then,
The subsequent process amount is displayed as a curve one after another for 7 hours. Also, if you want to see the operation details and alarm status corresponding to the process amount displayed on the curve, touch the position on the curve you want to see. Then, as shown in FIG. 6, the operation content that occurred at the time (rt±Δ11) corresponding to the touch position,
The alarm status is displayed in display areas A and B, respectively. Furthermore, for those display contents that cannot be completely displayed within the area, the user presses the operation update button E or the alarm update button. Then, the operation details or alarm status are updated and displayed one after another in these display areas.

This allows trainees to analyze the operating procedures they have performed after completing their training, and easily judge whether the response operations are good or bad when plant fluctuations occur.

Note that in the embodiment #-, an example is shown in which the CRT display 1 is used as the screen display device and the touch screen 1a is used as the screen instruction input device, but the present invention is not limited to this, and the double-sided display may be a liquid crystal display or a touch screen 1a. It is obvious that a screen display device such as a semiconductor can be used, and a screen instruction input device such as a mouse or a trackball can be used as the screen instruction input device.

[Effects of the Invention] As explained below, according to the present invention, when the NR performs self-taught plant operation training, the details of the operations performed by the trainees and the alarm status are displayed simultaneously with the process quantities. A simple driving training simulator device that can be viewed on the device makes it easy to analyze training operation procedures, easily grasps the important points in driving operations, and can be placed in the direction of driving operations. can get.
