Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a plant operation training simulator device for training operators of thermal power, nuclear power, hydroelectric power plants, or chemical plants.

(Conventional technology) With the modernization of plant control systems, an operator training simulator is used to acquire and improve the operating skills of operators who operate actual plants in order to cope with increasingly complex and sophisticated control systems. Training is underway.

For example, a thermal power plant, a nuclear power plant, a hydroelectric power plant, a chemical plant, etc. are composed of a large number of devices or devices.

Moreover, these devices and devices must be operated in conjunction with each other, and even when considering a single device or device, the interlock conditions are complex.
This is for each piece of equipment, so it takes a lot of time to memorize the operating procedures for all these pieces of equipment.
Operation, 91 buildings will be required.

By the way, if you try to start, stop, open, or close equipment or devices that make up the plant during operation training using this simulator device for operator training, please start the operation switch of the relevant equipment or device. This is done by stopping, opening, and closing operations, but if the interlock conditions for the device in question are not met, the device may not be in the desired state even if the operation switch is operated. . In such a case, a veteran operator trainer who has memorized all the interlock conditions for the relevant equipment can use an indicator, recorder, or system diagram on a CRT to show the process quantities for which the conditions are not met. It can be confirmed. Then, a corresponding operation is performed to change the condition-unsatisfied portion to a condition-satisfied state, and then the desired operation is performed again to bring the device into the desired state. However, in the case of operation trainees who do not remember the interlock conditions for the relevant equipment and equipment, first of all, in order to improve the operation, the interlock conditions for the plant component equipment and equipment are listed in the reference materials. For example, find a collection of device operation block diagrams, etc. 1
Next, find the operation block diagram of the corresponding device from among the huge number of devices or devices, and, referring to this operation block diagram, set each interlock condition one by one on the indicator, recorder, and CRT. Confirm with a system diagram, etc., find the part where the condition is not met, and perform the corresponding operation to change the part where the condition is not met to the one where the condition is met. Thereafter, the desired operation is performed again to bring the device to the desired state. Furthermore, even in the case of a driving training simulator device that has the function of displaying an operation block diagram of the equipment or device,
The operator training staff first CR the operation block diagram of the relevant equipment.
It is necessary to confirm each interlock condition described in the operation block diagram displayed on a display device such as a T device one by one using an indicator, a recorder, a system diagram on a CRT, etc.

(Problems to be Solved by the Invention) However, during plant operation training, especially when responding to an accident, it is often necessary to perform corresponding operations on equipment or equipment without waiting.

Therefore, even if operator training is conducted for operator trainees, if the training takes time and effort as described above, they will not be able to respond immediately to actual plant operations, resulting in less effective operation training. Therefore, it is an object of the present invention to provide a driving training simulator device that is highly effective in training and allows driving operations to be easily understood by both novice and experienced driving trainers.

[Structure of the Invention] (Means for Solving the Problem) The simulator device for plant operation training of the present invention particularly has the following features:
In addition to the system diagram necessary for plant operation, a screen data table that stores an operation block diagram representing the operation interlock of the equipment, and equipment information that stores detailed information necessary for the operation of the equipment. When it is determined that the interlock condition for the equipment is not satisfied based on the calculation result of the storage unit and the plant simulation calculation unit performed in response to the operation signal, the operation block diagram of the equipment is retrieved from the screen data table, and the operation block diagram of the equipment is retrieved from the screen data table. An operation block diagram is displayed on the screen display device after referring to the process amount data table to clearly indicate the locations where the interlock condition is not satisfied, and at the same time, upon request, the equipment information section informs the equipment where the interlock condition is not satisfied. The present invention is characterized by comprising an automatic screen display processing section that extracts detailed information about the device and displays it on the screen display device.

(Function) With the above configuration, when an operator trainer operates the operation switch of the equipment or equipment that constitutes the plant, if there is a part where the interlock conditions of the equipment or equipment are not met, the automatic screen display processing unit will display the information about the equipment or equipment. Alternatively, the screen information of the operation block diagram of the device is imported from the screen data table and automatically displayed on the display screen.

This allows the driver trainer to immediately know the reason why the condition is not met.

Additionally, at the request of the operator trainer, information such as the configuration diagram of the relevant equipment or device, operating procedures, and interlock setting basis is retrieved from the equipment information storage unit and displayed on the display screen, further improving training effectiveness. can be achieved.

(Example) FIG. 1 is a configuration diagram of a plant simulator showing an example of the present invention.

The CRT device 1 displays information necessary for operation training, such as a plant system diagram and an operation block diagram. The input processing unit 2 looks at the display and converts an operation request signal sent from the driving trainee via the operation switch 3 or the keyboard 4 into an operation signal, and performs the display control processing unit 5 or data update processing. It has a function of outputting to section 6. The display control processing section 5
The 0-screen data table 8 that receives a CRT screen display request signal from the input processing unit 2 or the automatic screen display processing unit 7, edits the screen, and displays it on the CRT device Wl is a system diagram and an operation block diagram necessary for plant operation. This is a table that stores screen information such as. When the automatic screen display processing unit 7 catches a condition failure signal that is output when the operation device or device cannot enter the intended operating state because the interlock condition is not satisfied, the automatic screen display processing unit 7 displays the operation block diagram or configuration of the corresponding device or device. The device information storage section 9 is a configuration diagram of the equipment or devices that make up the plant. , operating procedures, interlock condition setting grounds, etc. are stored in advance as images or text images for each device or device number. The process amount data table 10 is a table in which calculation results in the plant simulation calculation unit 11 are stored via the data update processing unit 6 each time. The data update processing unit 6 takes in the process quantity calculation results of the plant simulation calculation unit 11 at regular intervals, updates the process quantities, and stores them in the process quantity data table IO. The plant simulation calculation unit 11 uses the operation signals from the input processing unit 2 to perform calculations on dynamic characteristics such as pressure and temperature that represent the state of the plant, and logic characteristics calculations that simulate interlocks of each device or device that constitute the plant. Perform a simulated operation.

Next, the operation of this embodiment configured as described above will be explained in a second manner.
This will be explained with reference to FIGS.

Now, consider the case where pump A20 in the system diagram shown in FIG. 2 is started. As shown in the flowchart of FIG. 3, when the operator training person makes a start request using the operation/operation switch 3 corresponding to the pump A20 (301), the input signal first enters the input processing unit 2 and is processed as an operation signal. The data is sent from the data update processing section 6 to the plant simulation calculation section 11, and the pump A
Logic calculation processing for starting 20 is started.

The contents of the logic calculation are as shown in FIG. The timer 21 is set with a delay time from when the pump A20 receives a start command until it starts, and the operation signal S1 input to the timer 21 is output as an output signal 01 after the timeout time has elapsed.

Also, the startup condition check routine 22 is for pump A.
Checks whether the conditions for starting 2G are met (302), and if the conditions are met, outputs the start signal 02 (establishment of 303), and then outputs the output signal O1 on the timer side and the start condition check routine. A determination signal 03 as to whether the interlock condition is satisfied or not is outputted by ANDing the activation signals 02 on the side.

The determination signal 03 is stored in the process amount data table 10 via the data update processing section 6. At the same time, the status of the input/output points (Sl, S2, S3...) of each calculation section is
Tasks are also saved in the same way.

On the other hand, when the automatic screen display processing unit 7 detects the interlock condition determination signal S4 in the process amount data table IO (303 is not satisfied), the 1-condition failure determination signal S4 is detected.
The device number, the operation block drawing number, and the input/output points used to determine the interlock conditions are extracted from the operation block diagram setting table 8a shown in FIG. 5 in the screen data table 8 that corresponds to the storage order of Then, the operation block diagram of the pump A20 is extracted from the retrieved operation block drawing number (304 to 306), and the input/output points used to determine the interlock condition are the calculation input/output lines of the operation block drawing (304-306).

, to the display control processing unit 5, and displays an operation block diagram 30 that distinguishes between conditions satisfied and unsatisfied parts as shown in the CRT device cylinder 6 figure, and at the same time displays a request selection window 31 for displaying information regarding the pump A20. conduct.

At this time, if the driving trainer requests information display (309
), by making a request from the keyboard 4, a request signal is sent to the display control processing section 5 via the input processing section 2.1 The display control processing section 5 uses the device or device number corresponding to the determination signal as an index to select the device of the pump A20. Recall detailed information (e.g., structure diagram, operating procedure, interlock condition setting basis, etc.) from the device information storage unit 9 (310), C
A display is performed on the RT device 1 (311).

As a result of the above, even if a driver trainee becomes unable to understand driving operations during driving training, the CRT device@1 will automatically display detailed information about the locations where the interlock conditions are not met and the relevant equipment, allowing the driver to continue operating the vehicle. Be able to understand the content easily.

In the above embodiment, driving operations are performed using the operation switch 2 and the keyboard 3, but it goes without saying that a touch screen, a mouse, etc. may be used instead.

Furthermore, although only the automatic display was explained in the above embodiment, by adding the process shown in FIG. 7 to the automatic screen display processing section 7, it is possible to switch between automatic display, manual display, and no display of the operation block diagram. It is also possible to do this. That is, before a driver training person conducts training, he or she sets the operation block diagram display request to "Yes" or "No" in advance (701), and then operates the equipment (702).

During the process, if the interlock condition is not satisfied (70

), if the display request setting is "!!" (704 NO
), the operation block diagram is not displayed (NO in 705)
, If the driver trainer does not know the reason why the interlock condition is not met, he/she can change the display request setting from "no" to "yes" at that time (YES in 705).

[Effects of the Invention] As explained above, according to one aspect of the present invention, even though the equipment or devices constituting the plant are operated, if the interlock conditions are not satisfied and the intended operating state is not achieved, By automatically distinguishing between the parts where the interlock condition is not met and the part where the interlock condition is met for the same equipment or device, the operator trainer can easily know the reason why the condition is not met, and also provide detailed information about the equipment as necessary. Since the conditions can be easily known, learning efficiency in driving training can be improved.
