BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an operation training support device for supporting plant operation training by simulation, and particularly an operation performed by a trained person (hereinafter referred to as a trainee) according to the state of the plant. The present invention relates to a driving training support device that evaluates the adequacy of an operation error, analyzes the cause of an operation error, and supports the creation of a training policy and training materials based on these evaluation results and analysis results.

2. Description of the Related Art Nuclear power plants and advanced processes
Since the plant has a complicated structure and function, it requires a high degree of knowledge and skill to operate properly depending on the state of the plant. In recent years, in order to acquire the operation technology of this plant, operation training using a simulator that simulates the state of the plant has been performed. In this driving training,
The trainee operated the plant using a simulator, and the trainer evaluated the operation performed by the trainee while monitoring the plant state indicated by the simulator.

In the conventional driving training, the training contents are preliminarily organized as a curriculum, and the training is performed according to the curriculum. For example, in the case of retraining of operators of a nuclear power plant, training is performed in the order of normal plant start / stop, basic operation after reactor scram, single failure, and multiple failures.

The scenario for each of the above training events has been set in advance, and the standard operating procedure for the scenario has been set as the evaluation standard. Based on this evaluation criteria,
The trainer visually monitors the trainee's operations and checks the trainee's operation by referring to the checklist created in advance and the lighting of the annunciator that indicates a dangerous state of the plant state and the process values displayed by various instruments. Was evaluating the relevance.

The evaluation of the adequacy of the above-mentioned operation has been carried out based on the knowledge and experience of each training instructor.

[0006]

However, the operation of the plant in the event of an abnormality or accident of the plant is not always performed according to a preset procedure, and the plant state is taken into consideration while considering the final safety of the plant. It is important to drive appropriately according to the situation. For this reason, in the conventional driving training, a standard operating procedure was set as a temporary evaluation standard, but in the actual driving operation, the trainee performed many operations different from the set operating procedure. These driving operations cannot be said to be uniformly erroneous, and the training instructor evaluates whether or not the driving operations were appropriate from the standard operating procedures, depending on the situation at each moment. Was there.

[0007] However, in the driving operation training which progresses in real time, it is a heavy burden for the driving trainer to carry out such an evaluation successively. In addition, since the driving operation is performed one after another, there were cases where the cause of an important operation error was overlooked and feedback could not be given to the training.

Further, since one trainer usually teaches a plurality of trainees, the trainer cannot grasp the operations of all the trainees, and all the trainee's operation errors are accurately identified. It was difficult to give feedback to the training.

Further, since the validity of each operation is evaluated based on the knowledge and experience of each training instructor, the training standard cannot be made uniform, and the operation technique of the plant to be learned by the training instructor cannot be obtained. There was a different problem.

Further, the operation scenario used for the operation training of the conventional plant is set uniformly according to a predetermined training target, and its standard operation procedure is roughly set. Therefore, it was not intended to individually reinforce the flaws in the operation skills and knowledge peculiar to each trainee and to finely train the operation error that the trainee often makes.

Therefore, an object of the present invention is to solve the above-mentioned problem of the operation training of the conventional plant, reduce the burden on the training instructor in the training, and evaluate the operation operation sequentially performed according to the situation with a uniform standard. In addition, the purpose of the present invention is to provide a driving training support device that analyzes the cause of each trainee's operation error and supports the creation of a training policy / training teaching material including the training content required for the trainee.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows the configuration and information flow of a driving training support device according to an embodiment of the present invention. The driving training support device 1 of the present embodiment includes a trainee man-machine interface 2, a driving data collection device 3, a driving data processing device 4, a driving evaluation device 5, and a driving evaluation knowledge base 6.
A training machine man-machine interface 7, an image data collection device 8, a sound data collection device 9, a multimedia control device 10, an image sound database 11, an error cause analysis device 12, and a training policy guide device. 13,
It comprises a training policy knowledge base 14 and a teaching material creation device 15.

This operation training support device 1 is connected to a plant simulator 16 so that a trainee can operate a plant in a simulated manner through a trainee man-machine interface 2.
This operation is configured to be input to the plant simulator 16.

The plant simulator 16 simulates a plant state based on the operation performed by the trainee and displays it on the trainee man-machine interface 2.
On the other hand, the operation data collection device 3 collects the plant state of the plant simulator 16 and the trainee's operation as operation data so as to be mutually compatible. Here, as the information on the plant state, for example, various kinds of announcer information (specifically, there is announcer information for warning the reactor water level decrease) accompanying the reactor scrum, reactor water level and pressure, etc. Process values of plant parameters are mentioned. In addition, as the information regarding the driving operation performed by the trainee, there is operation information such as switching of a mode switch by an operator in four modes of driving, starting, refueling, and stopping.

The operation data processing device 4 integrates and organizes the operation data collected by the operation data collecting device 3.
This is because the driving operation performed by the trainee has a large number of operations, and the same operation is often repeated, so that the driving data collected by the driving data collection device 3 becomes large and remains as it is. This is because it is not efficient to use for driving evaluation.

The operation data processing device 4 collects similar operation data and arranges them in a time series so that the plant state and the flow of the operation operation can be easily grasped.

The operation evaluation device 5 is the operation data processing device 4
With respect to the driving data organized and integrated in (3), the validity of the driving operation is evaluated by referring to the evaluation criteria stored in the driving evaluation knowledge base 6, and the evaluation result is output to the man-machine interface 7 for the training instructor.

The driving evaluation knowledge base 6 stores the driving evaluation knowledge necessary for evaluating the adequacy of the driving operation. This operation evaluation knowledge is not one in which standard operating procedures assumed in advance are stored in time series as evaluation criteria, but evaluation knowledge for evaluating the plant state at that time and the adequacy of the operating operation for controlling it. Are ruled independently of each other.

FIG. 2 shows an example of the evaluation criteria stored in the driving evaluation knowledge base 6. The evaluation criterion A in FIG. 2 is that if the reactor water level reaches a high level of level 7 and the turbine-driven feedwater pump is operating, it is determined that excess water has been supplied to the reactor, and the turbine-driven feedwater pump It is evaluated that the trip operation of is forgotten. Further, the evaluation criterion B in FIG. 2 is that the reactor water level is further lowered even when the reactor water level is as low as level 3, and if the turbine drive water feed pump manual trip operation is performed at that time,
It is judged that the trip operation is an operation that interferes with the necessary supply of water to the reactor, and is evaluated as an erroneous operation.

The operation evaluation device 5 inputs the operation data of the operation data processing device 4 and collates the operation data with the evaluation criteria of the operation evaluation knowledge base 6 so that the trainee's operation operation corresponds to the plant state at that time. Evaluate whether it was appropriate or not. This evaluation evaluates not only the operation performed by the trainee but also the operation not performed by the trainee. For example,
In the process of searching the operation data in time series, the parameter that the reactor water level reached level 7 was turned ON,
If the parameter that the turbine drive water supply pump is operating at that time is ON, it means that the if part (condition) of the evaluation standard A is satisfied, and the turbine drive water supply pump trip of the then part (evaluation result). Evaluate that you forgot the operation.

The above evaluation result is output to the man-machine interface 7 for the training instructor, and the training instructor can obtain the evaluation result for the operation of the trainee and why the man-machine interface 7 for the training instructor is used. The operation evaluation device 5 can be inquired whether the evaluation result has been output. In response to this inquiry, the driving evaluation device 5 outputs information such as the content of the evaluated evaluation standard and the time when the if part of the evaluation standard is satisfied to the man-machine interface 7 for the training instructor.

Further, the training instructor can correct the evaluation standard or add a new evaluation standard through the man-machine interface 7 for training instructor, and the plant simulator 16 through the man-machine interface 7 for training instructor.
Can also be disturbed. As a result, the evaluation standard can be modified or the desired content can be intentionally trained.

Next, the cause analysis of the operation error of this apparatus and the support for creating the training policy will be described. Trainees have their own specific lack of driving skills and knowledge, and if it is possible to identify the lack of knowledge and skills and create a training policy that emphasizes these lacks, it will be more effective. Training can be done.

When there is an error in the trainee's driving operation, the error cause analyzer 12 operates at which point in time the trainee operates during a series of operations from recognition of the plant state to appropriate driving operation. Make an error and identify what the operation error was.

FIGS. 3, 4 and 5 are flowcharts for identifying the cause of the operation error. The vertical flow in FIGS. 3 and 4 shows the operation standard of the operator at each point from the recognition of the plant state to the correct operation operation, and the one shown on the right side of each operation standard does not meet the standard. Indicates the cause of the operation error in. FIG. 5 shows FIG. 3 and FIG.
3 shows a decision tree for identifying a more detailed error cause of the operation error cause identified in.

In the present embodiment, from the recognition of the plant state to the correct operation operation, "has the operator aware of the necessity of action?" (Step 21), "action related to the current plant state" Did you take it? "(Step 2
2), "Have you set the final goal according to the plant operation policy?" (Step 23), "Is the target plant status compatible with the final goal and the current plant status?" (Step 24), " Does the task performed by the operator lead the plant to the target state correctly? (Step 25), "Is the detailed execution procedure of the task appropriate?" (Step 26), "Is the individual step of the procedure performed correctly? ? "(Step 27).

Now, for example, when the trainee is aware of the necessity of action, but takes action that does not suit the plant state at that time, "error of state identification" (step 31).
Is judged. The cause of this operation error is analyzed in more detail by the decision tree of FIG. Further, in the decision tree of FIG. 5, if, for example, the trainee did not evaluate a predetermined parameter in the displayed plant states, "there are some of the known states that have not been evaluated". (Step 32) is analyzed, and the reason for not performing further evaluation is, for example, "premature end of state identification".
(Step 33), and the root cause of the error that caused this error cause is identified, for example, "Distribution of attention by other competing activities" (Step 34).

The training policy guide device 13 determines the cause of the operation error identified by the error cause analysis device 12 together with the specific content of the operation error in the training policy knowledge base 1
It records in 4 and searches whether the trainee made the same operation error in the past. If the trainee has made the same operation error due to the same cause in the past,
Present a training policy that strengthens the lack of knowledge and skills of the trainees who caused the error, and guide the creation of the training policy.

Next, the support for creating the training material according to this embodiment will be described. Generally, if one can visually and auditorily confirm his / her behavior at the time of making an operation error, the behavior is strongly impressed and stored. The driving training support device 1 of the present embodiment records the behavior and conversation of the trainee who operates as image data and voice data, and incorporates the behavior and conversation of the trainee at the time of an operation error into the training material, It aims to provide more effective training materials.

As shown in FIG. 1, the driving training support device 1 of the present embodiment comprises an image data collecting device 8 and a voice data collecting device 9, and these devices serve as image data for the behavior and conversations of trainees during training. Collect as voice data. The multimedia control device 10 controls the image data collection device 8 and the audio data collection device 9 and processes the image data and audio data collected by these devices and stores them in the image / audio database 11.

When the training policy guide device 13 creates a policy for training in a state where a specific operation error occurs, the training instructor uses the teaching material creation device 15 to generate image data at the time when the trainee makes an operation error. It is possible to take out audio data from the image / audio database 11 via the multimedia control device 10 and create a training material incorporating this.

FIG. 6 shows an example of a training material incorporating image data and audio data displayed on the man-machine interface 7 for the training instructor. In this training material, image data is stored in time series from the start of the training, and the image data is displayed on the main frame of the training material screen, particularly at the points that are points in training.

According to this training material, when the reactor scrum occurs 41, forget the trip operation of the turbine-driven feedwater pump 4
The behavior and utterances of the trainee at each point 2 are shown in the main frame of the training material screen. This allows the trainee to learn by looking at his / her behavior at the time of making the operation error.

According to the operation training support device 1 of this embodiment, the operation data collecting device 3 collects the plant state and the trainee's operation at each point in time as operation data, and the operation data processing device 4 organizes and integrates this. However, since the operation evaluation device 5 can apply the evaluation criteria of the operation evaluation knowledge base 6 to evaluate the trainee's operation in a short time, the burden on the trainer is reduced and the operation error of the trainee is prevented from being overlooked. it can. In this case, since the evaluation standard stored in the operation evaluation knowledge base 6 is for evaluating the validity of the operation corresponding to each plant state, the trainee performed an operation deviating from the operation scenario assumed in advance. Appropriate evaluations can sometimes be performed, and the trainees can flexibly respond to actual operations.

Further, since the validity of the trainee's operation is evaluated uniformly by the evaluation standard stored in the driving evaluation knowledge base 6, the evaluation standard becomes clear and uniform training can be performed.

Further, since the cause of the operation error of each trainee is identified by the error cause analysis device 12 and is systematically recorded in the training policy knowledge base 14, the individual causes stored in the training policy knowledge base 14 are identified. Training history of trainees,
Using the history of operation errors and the error cause analysis result by the error cause analyzer 12, it is possible to support the creation of a training policy according to the characteristics of each trainee.

Further, the image data collecting device 8 and the voice data collecting device 9 collect the behavior of the trainee who is operating as image data and voice data, and the teaching material preparing device 15 collects the image data and voice at the time when the operation error occurs. Since the training material can be created by incorporating the data, it is possible to efficiently perform the training to prevent the recurrence of the error while confirming the behavior of the user who has made the operation error.

[0046]

As is apparent from the above description, according to the driving training support apparatus of the present invention, the driving data collecting apparatus collects the driving operation of the trainee and the plant state at the time of the operation as the operating data. In addition, since the driving evaluation device evaluates driving operations in a short time based on the evaluation criteria of the driving evaluation knowledge base, it reduces the burden on the training instructor and prevents oversight of operation errors. Homogeneous and reliable driving training can be performed.

Further, according to the driving training support apparatus of the present invention equipped with the error cause analysis device, the training policy guide device, and the training policy knowledge base, the error cause analysis device causes an error unique to each trainee. The cause is also analyzed and recorded systematically by trainee in the training policy knowledge base. Further, by using the training policy guide device to search for and present the operation error and the cause of the error, it is possible to create the training policy including the training of the operation error that each trainee is likely to make.

Further, in the driving training support device provided with the image data collecting device, the voice data collecting device, the multimedia control device, the image voice database and the teaching material preparing device, the image data collecting device, the voice data collecting device and the multimedia controlling device are provided. The behavior of the trainee at the time of making an operation error is collected as image data and voice data, stored in the image voice database, and when the training teaching material is created, this image and voice data is taken out by the teaching material creation device and its driving operation You can display the behavior of the trainee at the time when you make an operation error on the operation screen of the trainee, so by checking your own behavior at the time of the operation error, you can efficiently prevent recurrence of the operation error. You can create teaching materials.
