Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Field of Industrial Application) The present invention relates to an operation training evaluation support device that supports an instructor, including evaluation, when the instructor implements training of a plant operator.

(Prior Art) Generally, an operator who operates a plant such as a nuclear power plant, a thermal power plant, or a chemical plant implements operation training as necessary.

The operation of the operator during the training is identified by the instructor directly observing the operator from a distance or, in the case of the operation of turning on a lamp or the like, by the lighting state of the lamp or the like. Further, the operation of the operator can be identified by indirect observation in which the operator during training is photographed by a television camera or the like and the instructor observes the image in the instructor console.

In this way, the operation of the operator during training is identified, and from this operation, the instructor grasps the purpose and contents of the operation,
It was common practice to evaluate the suitability of the operation.

(Problems to be Solved by the Invention) However, in the case of direct observation, since the observation is performed from a distance, the operation status of the operator becomes difficult to see in the shadow of the operator, and the instructor is instructed by the operator. It is difficult to judge all operations on the spot, and it is also difficult to store all operations. Therefore, the evaluation of the operation of the operator may not be accurate.

In addition, in the case of indirect observation, the TV camera does not always photograph the operator for each of the control panels. This is a situation in which it is difficult to determine which operation has been executed by which operation panel. Also, in this case, the TV camera usually shoots from behind the operator, and the operation status of the operator may be difficult to see because of the shadow of the operator, and as a result, the burden on the instructor increases, There is a problem that the eligibility and objectivity of evaluation may be impaired.

The present invention has been made in view of the above-described circumstances, and provides a driving training evaluation support device capable of reducing the burden on an instructor and accurately evaluating the operation of a driver. With the goal.

[Configuration of the invention]

(Means for Solving the Problems) In order to achieve the above object, a driving training evaluation support device according to the present invention is connected to a plurality of operation panels and simulates a plant with operation data from the operation panels. A data collection device that is connected to a simulator and collects the operation data and plant process data from the simulator; and operates from a database that is connected to the data collection device and stores the collected data and operation evaluation knowledge collected by the data collection device. An operation error extraction device that extracts errors, and an evaluation that derives and evaluates the error rate in each system from each plant operator based on the plant impact, the number of operation opportunities, and the number of errors that are weighted according to the magnitude of the impact on the plant. Displays the device, the process data, the operation data, the operation error, and the like. And a display device for displaying operation and alarm data near the extracted time.

(Operation) According to the present invention configured as described above, by performing real-time display of data collected by the data collection device during training, the operation status can be reduced even for operations that are not visible in the shadow of the operator. It becomes easy to grasp, and the instructor can confirm that the operation error has occurred by displaying the operation error extracted by the operation error extraction device. Furthermore, by displaying the evaluation results performed by the evaluation device after the training, the instructor is supported, and the trainees' understanding of the driving operation is reduced, thereby reducing the burden on the instructor and improving the operation of the operator. The evaluation can be performed without losing the objectivity.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 shows a block diagram. In FIG.
The driving training evaluation support device 1 includes a simulator 2, a data collection device 3 connected to the simulator 2, an operation error extraction device 4 connected to the data collection device 3,
An evaluation device 5 connected to the operation error extracting device 4,
It mainly comprises a display device 6 connected to the evaluation device 5.

The simulator 2 is connected to an operation panel 7 on which a number of operation switches, meters, lamps and the like are installed. When a plant operator during operation training operates an operation switch, the simulator 2 inputs the operation data from the operated operation switch to simulate an actual plant.

On the other hand, a first database 8 that stores operation evaluation knowledge is connected to the operation error extraction device 4. The operation evaluation knowledge is obtained by using a condition for determining an erroneous operation as knowledge. As described above, the operation error extracting device 4
It has operation evaluation knowledge as the first database 8 and extracts an operation error from this and the collected data collected by the data collection device 3. In this case, the extraction of the operation error is not limited to the actual operation. It is done even if you forget to do it.

For example, if the operation is not performed even though the plant state is in a certain state (condition), the operation is forgotten and extracted.

The operation error extracted by the operation error extraction device 4 is sent to the evaluation device 5 and recorded.

The evaluation device 5 stores the position of the operation switch on the control panel 7 on the panel and the attribute to which the switch belongs to the second system.
The second database 9 is used to classify the operation data of the collected data at the board position and for each system.

After the training is completed, the evaluation device 5 performs the ranking according to the content of the recorded operation error. This ranking is made, for example, from large to medium and small according to the degree of influence on the plant. Further, the error rate for each system is obtained as the number of errors per operation opportunity from the number of operation opportunities and the number of errors for each system. At this time, weighting is performed according to the magnitude of the influence on the plant, and the error rate increases as the degree of influence increases. Similarly, for each operator, the error rate and operation error of each system are classified.

And these results are the training history of the operator,
It is stored in the second database 9.

The display device 6 includes an operation / alarm data display unit, a process data display unit, an extraction error display unit, and an evaluation result display unit, and these are displayed on the CRT 10.

The operation / alarm data display unit operates the plant data collected by the data collection device 3 and displays the alarm data on the CRT 10 as shown in FIG. 2, for example. In this case, in order to easily distinguish the operation data from the alarm data, it is desirable to display the operation data in a different color such as displaying the operation data in green and displaying the alarm in red.

It is also intended to provide a means for facilitating the display of a particular operation or alarm. This is because, by registering a specific operation or alarm in advance, all operations and alarm times registered by the collected data are stored, and all the operations and alarm times registered according to the request after the end of the training are stored. It is displayed as a menu, and by selecting the time from this menu, the operation and alarm data near the selected time are displayed.

In this case, the display time of the process data display synchronized with the operation / alarm data display also changes.

The process data display unit displays the process data of the plant data on the CRT 10. In order to make it easier to predict trends in the future,
For example, this is performed by a trend display method as shown in FIG. A plurality of such displays, for example, one always displays basic process data indicating the state of the plant, and the other displays a designated process data of interest. Here, the history of the time of the data displayed on the process data display section is displayed with the latest time displayed on the operation / alarm display section as a reference time.

Thus, when the display time changes by changing the position of the display data on the operation / alarm display unit, the display time of the process data displayed on the process data display unit also changes.

As shown in FIG. 4, the extraction operation error display section displays on the CRT 10 a time at which an error was extracted and a title indicating an outline of the error. Also, if the extracted error is a recoverable error and recovery has been made,
The recovered time is displayed as shown in FIG. In this case, it is desirable that the display is performed in a color different from the display color of the already displayed extraction time, and the display color of the error title is also changed to the same color.

In the extraction operation error display section, for the displayed error, a means for displaying the reason and further the technical background, and an operation /
A means is provided for displaying alarm data. For example,
In FIG. 4, the reason for the error is displayed by moving the cursor to and selecting the error title, and the technical background is displayed by moving and selecting the cursor on the reason for the error. Further, by moving the cursor over the extracted time and selecting it, the time displayed on the operation / alarm data display section is changed to the time including the extracted time.

The display result display unit displays a result evaluated by the evaluation device 5.

According to the embodiment configured as described above, during the training, the data collected by the data collection device 3 is displayed in real time. Is easy to grasp.

In addition, the title of the operation error is displayed at the time when the operation error is extracted by the operation error extraction device 4, so that the instructor can confirm that the operation error has occurred.

Further, when this error is a recoverable error, the time when the error was recovered is displayed. At the same time, the display color of the title of the error and the recovery time is changed, and the display of the extracted error by rank and the error status by system based on the error rate are performed.

After the training is completed, the result of the evaluation performed by the evaluation device 5 is displayed, and the reason and the technical background of the extracted error are displayed to assist the instructor and to train the trainee. It can help you understand the operation.

〔The invention's effect〕

As described above, according to the driving training evaluation support device according to the present invention, the burden on the instructor can be reduced,
The evaluation of the operator according to the importance and the time of the plant can be accurately performed without impairing the objectivity. In particular, since the evaluation is performed for each system, there is an effect that it is possible to grasp the system that each operator is not good at and perform appropriate training.
