Description

The present invention relates to an operation and maintenance training system and an operation and maintenance training method for conducting operation and maintenance training for various facilities such as nuclear fuel cycle facilities such as enrichment plants, reprocessing plants, and MOX plants, facilities of thermal, hydroelectric, and nuclear power plants, and chemical plant facilities.

Conventionally, for example, operational training (operator training) for real plants (real equipment) such as nuclear fuel cycle facilities has been conducted virtually using an operational training simulator device such as a personal computer or an operational training machine that has installed software that enables the same monitoring and operation as the real equipment used in nuclear fuel cycle facilities, and the operator operates an operating keyboard while watching a display device such as a monitor (operation monitoring panel) of the operational training simulator device.

In addition, maintenance training (training for maintenance personnel) involves training in disassembly and inspection work, cleaning work, repair work, assembly work, etc., using simulators (training equipment) such as valve devices, such as air-operated valves (AO valves), electrically-operated valves (MO valves), and heat exchange control valves, as well as auxiliary equipment simulators with structures equivalent to auxiliary equipment, such as fan units, pump units, and motor units, that are used in actual plants, such as nuclear fuel cycle facilities.

In addition, simulators were used for control panels and electrical panels, which are used in actual plants such as nuclear fuel cycle facilities, and maintenance training was conducted on disassembly and inspection work, cleaning work, repair work, assembly work, etc.

For example, a conventional nuclear power plant operation training simulator is disclosed in Patent Document 1.

JP 2011-158685 A

However, because operation training and maintenance training are different types of training, they are treated as separate education, and traditionally training was conducted separately in dedicated training locations.

In addition, maintenance training for valve mechanisms and auxiliary machinery, maintenance training for control panels, and maintenance training for electrical panels were also conducted separately.

Therefore, in the past, training was conducted without taking into account the plant's operating and maintenance conditions, and was different from the actual operating and maintenance work conditions.

In addition, the operation training equipment (functions) used in the above conventional simulations were process-based equipment that handled air, steam, solutions, etc., and there was no operation training equipment for mechanical equipment (facilities), so training for these facilities was conducted using actual equipment (actual equipment OJT).

The above-mentioned mechanical equipment refers to machinery (devices) that mechanically operate part or all of the equipment, change its position, move an object, or perform processing such as cutting, when supplied with energy from inside or outside. For example, this refers to devices (devices) that transport drums using a conveyor system, transport heavy objects using a crane system, transport equipment using unmanned loading and unloading vehicles such as automatic forklifts, cut parts using cutting devices for equipment such as arc cutting devices, grab and release equipment using a gripping device, and perform partial operations such as valves that make up a process system.

As this was carried out using actual mechanical equipment, there was a high risk of operating the equipment incorrectly or damaging it.

The present invention is intended to eliminate the above drawbacks.

The plant operation training and maintenance training system of the present invention comprises a training room forming one area, and a simulation device for operation training of an actual plant and a simulator for maintenance training of the actual plant, both installed in the training room. The training room is characterized by being capable of simultaneously conducting operation training for operation trainees and maintenance training for maintenance trainees.

In addition, a maintenance training simulator simulation software capable of simulating the maintenance training simulator is provided, and a changeover switch unit is provided for connecting the operation training simulation device to either the maintenance training simulator or the maintenance training simulator simulation software.

The above-mentioned operation training simulation device is also characterized by having common equipment operation software that can simulate the operation of the plant building ventilation equipment, electrical equipment, and solution transfer and receiving equipment.

The above-mentioned simulation device for operation training is characterized by comprising a computer device installed with software that enables monitoring and operation in the same manner as the actual equipment used in the actual plant, and a display device and a large display device connected to the computer device.

The driving training simulation device is also characterized by having software for simulating the driving operation of mechanical equipment and/or simulating the monitoring of said driving operation.

The driving training simulation device is also characterized by having a large display device, and a means for synchronizing the video/image with the driving operation by a synchronization means and displaying the video/image on the large display device.

The display device or large display device is also characterized by having a means for displaying information on the operating status of the target mechanical equipment in addition to the video/image.

The information on the operating state of the target mechanism is the amount of change in the state of the mechanical devices according to the playback time of the recorded video/image, calculated from the relationship between the change in state of the mechanical devices and the recording time of the video/image of the change in state of the devices, and is characterized by having a display means for displaying the amount of change on a display device.

The large display device is also characterized by having multiple displays.

The operation training simulation device is also characterized by being provided with a detection device that detects whether or not the maintenance training simulator is being maintained.

The following drawings explain an embodiment of the present invention.

1.1. Explanation of the system configuration

Figures 1 to 4 show an example of the plant operation training and maintenance training system for various facilities such as nuclear fuel cycle facilities, thermal, hydroelectric and nuclear power plants, and chemical plant facilities of the present invention. In the present invention, in a training room 1 forming one area (room), an operation training simulation device 2 that can monitor and operate in the same way as an actual plant (actual machine) used in a nuclear fuel cycle facility, and a maintenance training simulator for the actual plant are installed, so that operation training and maintenance training can be carried out simultaneously in the training room 1.

Note that an area (room) refers to a room that forms a single space, for example, a room that does not have any walls that completely separate the room.

Also, for example, even if the room in which the operation training simulation device 2 is installed is different from the room in which the maintenance training simulator is installed within the same training center (facility) (not on-site), if information about one or more other rooms can be obtained from a certain room via a monitor or the like, the rooms may be considered as one area.

The above-mentioned maintenance training simulators include, for example, a maintenance training control panel simulator 3 that imitates a control panel used in the above-mentioned nuclear fuel cycle facility, a maintenance training electrical panel simulator 4 that imitates an electrical panel used in the above-mentioned nuclear fuel cycle facility, an auxiliary equipment simulator 5 that imitates auxiliary equipment such as compressed air supply devices, fan devices, pump devices, motor devices, and other electric motor-driven devices used in the above-mentioned nuclear fuel cycle facility, and a maintenance training valve device simulator 6 that imitates a remotely operated valve device used in the above-mentioned nuclear fuel cycle facility.

The above-mentioned operation training simulation device 2 is composed of a simulation calculation storage device unit 2a having software capable of monitoring and operating in the same manner as an actual device used in, for example, a nuclear fuel cycle facility, a calculation storage device unit 2b for instructor screen display and operation, a screen display device unit 2c for instructors such as a monitor connected to the calculation storage device unit 2b for instructors, a calculation storage device unit 2d for operator training screen display and operation for operation trainees, a screen display device unit 2e for operator trainees such as a monitor connected to the calculation storage device unit 2d for operation training, a large screen display device unit 2f, and a large screen display calculation storage device 2g that obtains the process state from the simulation calculation storage device unit 2a and displays it on the large screen display device 2f.

The simulation calculation and storage device unit 2a, the instructor calculation and storage device unit 2b, and the driving training calculation and storage device unit 2d are connected to each other via signal wiring, such as a network, and are configured to be able to exchange signals.

For example, if an instructor outputs an actual driving simulation command or an abnormality simulation signal from the instructor calculation and storage device unit 2b to the simulation calculation and storage device unit 2a, based on this command, the simulator calculation and storage device unit 2a will display the process state such as the actual driving simulation or abnormality simulation on the screen display device unit 2e for driving training via the calculation and storage device unit 2d for driving training, and the driving trainee will be able to carry out driving training based on this.

The simulation calculation storage device unit 2a also causes the process state to be displayed on the large screen display device unit 2f via the large display screen display calculation storage device 2g.

The simulation calculation storage device unit 2a may have, for example, standalone software capable of monitoring and operating in the same manner as an actual device, or it may have common equipment operation software capable of simulating the operation of the plant building ventilation equipment, electrical equipment, and solution transfer and receiving equipment, which are commonly used in various plant facilities.

Furthermore, the simulation calculation storage device unit 2a may also have software for operating and monitoring mechanical systems, such as devices for moving objects to be moved, such as the transport of drums by a conveyor system, the transport of heavy objects by a crane system, and the transport of equipment by an unmanned loading and unloading vehicle, such as an automatic forklift, for cutting components by an equipment cutting device, such as an arc cutting device, for gripping and releasing equipment by a gripping device, and for performing partial operations, such as valves that constitute a process system, at the site, and for monitoring the operation and simulating the operation.

The instructor calculation and storage device unit 2b and the operation training calculation and storage device unit 2d may have an operation unit capable of operating and monitoring in the same manner as the actual machine, as well as an operation unit (operation switch, etc.) capable of operating and monitoring in the same manner as the common equipment operation, and an operation unit (operation switch, etc.) capable of operating and monitoring in the same manner as the operation of mechanical equipment, thereby forming a simulated instructor panel, a simulated operation and monitoring control panel, and a simulated on-site operation panel. Note that one or more corresponding instructor panels, operation and monitoring control panels, and on-site operation panels may be provided for each operation.

In addition, the above-mentioned calculation storage processing unit 2a, 2b, 2d, etc. may be provided on the operation monitoring control panel and on-site operation panel of the actual machine such as the actual mechanical system, and when training is performed by simulation, a switching device may be provided to prevent the above-mentioned actual machine from operating.

The maintenance training control panel simulator 3 includes, for example, a simulator 3a such as an ANN (annunciator) and a simulator 3b having a control unit 7 that controls each of the above simulators, such as a PLC (Programmable Logic Controller).

In addition, each of the control panel simulators 3 is provided with a relay section 3c, a lamp section 3d, a fan section 3e, etc., just like the actual device, as well as a switch section 3f for the main body of the control panel simulator 3 and switch sections 3g corresponding to each control section, fan section, etc.

The above switches are configured so that they can be electrically disconnected (isolated) or connected (restored) by turning them on and off.

The relay unit 3c, lamp unit 3d, fan unit 3e, and switch units 3f and 3g may be simulated devices (dummy devices) that imitate them.

The maintenance training electrical panel simulator 4 is, for example, a simulator of an MCC (motor control center).

The above-mentioned maintenance training auxiliary equipment simulator 5 may be, for example, a simulator of a fan device, a pump device, a motor device, etc. The above-mentioned maintenance training valve equipment simulator 6 may be, for example, a simulator of an air-operated valve (AO valve), an electrically-operated valve (MO valve), a control valve, etc. These simulators may be actual ones that are externally controlled to open and close the valves and drive the fans, or they may be dummies.

Then, just like with the actual machine, for example, the operation training simulation device 2 and each of the maintenance training simulators are connected (linked) with signal wiring (signal cable) or dummy wiring (dummy cable), and the maintenance training simulators are connected (linked) with each other with signal wiring or dummy wiring.

The operation training simulation device 2 can acquire the status of each of the maintenance training simulators via, for example, the signal wiring, and can operate each of the maintenance training simulators. The operation training simulation device may be provided with a determination device for determining, from the status of the maintenance training simulators, whether or not maintenance training for the maintenance training simulators is being performed .

In addition, each of the simulators may be provided with a separate detection unit (determination unit) that detects (determines) whether maintenance is required, and the driving training simulation device 2 may obtain the maintenance status from the detection unit.

The operation training simulation device 2 and each of the maintenance training simulators are connected to, for example, a power supply source provided separately outside via power wiring (power cable). The power supply source may be connected to other maintenance training simulators via the power panel simulator 4.

That is, the operation training simulation device 2, which can monitor and operate simulated machines such as control panels, electrical panels, auxiliary machines, and valve devices in the same way as real machines, the control panel simulators 3, and the electrical panel simulator 4 are each connected (linked) by signal wiring via a HUB (wire concentrator) 8 or the like, so that electrical signals can be exchanged between them. Note that the signal wiring may be dummy wiring.

In addition, similar to the actual machine, the electrical panel simulator 4 is provided with, for example, a power input unit 11 connected to an external power supply source 9 for the electrical panel simulator via a power wiring 10, and a power output unit 12 that outputs the power input to the power input unit 11 to the outside.

In addition, the auxiliary equipment simulator 5 such as a fan device is provided with, for example, a power supply wiring (power cord) 13, and the valve equipment simulator 6 is provided with, for example, a power supply wiring (power cord) 14. Then, for example, by connecting the connection plugs of the power supply wiring 13, 14 of the auxiliary equipment simulator 5 and the valve equipment simulator 6 to the power output section 12 formed in the shape of a socket, power from the power supply source 9 is supplied to the auxiliary equipment simulator 5 and the valve equipment simulator 6.

Then, by unplugging the connection plug from the power output unit 12, it becomes possible to isolate the auxiliary machinery simulator 5 and the valve device simulator 6 from the electrical panel simulator 4.

In addition, for example, the power supply wiring 10 on the side of the electrical panel simulator 4 and the power supply wiring 10 on the side of the power supply source 9 are each provided with a molded-case circuit breaker (MCCB) (not shown) so that the power supply can be cut off (disconnected) and connected (restored), respectively, thereby isolating the corresponding equipment.

In addition, like the actual machine, each of the control panel simulators 3 is provided with a power input section 17 that is connected to an external power supply source 15 for the control panel simulator via a power wiring 16, as shown in FIG. 3, for example.

The power supply wiring 16 on the control panel simulator 3 side and the power supply wiring 16 on the power supply source 15 side are provided with circuit breakers (MCCB) 18, 19, respectively, so that the power supply can be cut off (disconnected) and connected (restored).

The power supply wiring 18, 19 may be dummy wiring. Also, a circuit breaker may be provided on any of the power supply wiring.

The valve device simulator 6 is provided with an operation unit 20 that operates the simulator, for example, by opening and closing the valve, and a state detection unit 21 that detects the state of the simulator, such as the degree to which the valve is open and closed, and is configured so that the operation unit 20 can be operated, for example, from the control unit 7 of the control panel simulator 3 via a signal wiring 22.

The operating unit 20 of the valve device simulator 6 can, for example, operate the opening and closing degree by a motor, by the amount of air, or by the amount of current.

The control unit 7 is also configured to be able to detect the state of the valve device simulator 6 from the state detection unit 21, for example, via the signal wiring 23.

In addition, if the operation unit 20 of the valve device simulator 6 is operated by the amount of electricity (amount of current) from the electric panel simulator 4, the control unit 7 may be configured to be able to control the amount of electricity (amount of current) from the electric panel simulator 4 via the signal wiring 24 and the power wiring 14, thereby operating the operation unit 20.

Similarly, the auxiliary machine simulator 5 may also be provided with an operation unit (not shown) for operating the auxiliary machine simulator, such as the rotation of the fan, and a status detection unit (not shown) for detecting the status of the simulator, such as the rotation speed of the fan, and configured so that the operation unit can be operated from the control unit 7 of the control panel simulator 3 via signal wiring.

The control unit 7 may also be configured to detect the state of the auxiliary machine simulator 5 from the state detection unit via the signal wiring.

In addition, if the operation unit of the auxiliary machine simulator 5 is operated by the amount of power (amount of current) from the electric panel simulator 4, the control unit 7 may be configured to be able to control the amount of power (amount of current) from the electric panel simulator 4 via the signal wiring 24 and the power supply wiring 13, thereby operating the operation unit.

The electrical panel simulator 4 is also provided with a power connection detection device 25 that detects the power connection state with the auxiliary machine simulator 5 or the valve device simulator 6, and the power connection state detected by the power connection detection device 25 can be output to the control panel simulator 3 or the operation training simulation device 2 via the signal wiring 26.

In addition, the control unit 7 of the control panel simulator 4 may be provided with a simulation unit 27 that can virtually simulate the state of simulators such as auxiliary equipment and valve devices, and a mode changeover switch unit 28 that switches the operation training simulation device 2 between a first connection unit that connects to the signal wiring from the simulator via the control unit 7 or the like, and a second connection unit that connects to the simulation unit 27, so that even if the desired simulator is isolated, the operation trainer can perform operation training on the simulator.

The simulation unit 27 may be provided within the driving training simulation device 2.

In addition, a backup simulation device 29 may be provided for the driving training simulation device 2, and the backup simulation device 29 may be used to provide training equivalent to that provided by the driving training simulation device 2.

In addition, any of the signal wiring and power wiring may be used as a dummy wiring, or wiring may be omitted.

In addition, isolation means such as an on-off switch or a wiring breaker may be provided at any position on any wiring.

The isolation means may also be a means for removing wiring from the equipment or a means using a cable list.

1.2. Explanation of an example system

FIG. 7 is a system diagram showing an example of the driver training system of the present invention.

In this embodiment, prior to actual operation training using actual mechanical equipment, the trainee undergoes training using the above simulation to acquire basic operating skills for operating the mechanical equipment.

As shown in FIG. 7, the operation training system is composed of a simulation calculation storage device 2a in which software for operating and monitoring the mechanical equipment is installed and which can perform operations similar to those of an operation monitoring control panel installed in a centralized monitoring area of the plant, an instructor's calculation storage device 2b, an instructor's screen display device 2c connected to the calculation storage device 2b, an operation training calculation storage device 2d, an operation training screen display device 2e connected to the calculation storage device 2d, a large screen display device 2f, a centralized calculation storage device 39, and signal wiring 40 such as a LAN cable that connects these, and is configured so that signals can be exchanged via a network or the like through the signal wiring.

Furthermore, the above-mentioned operation training system may be provided with an on-site operation panel having a calculation and storage device unit in which software capable of simulating the operation of on-site mechanical equipment, which can be operated in the same manner as an on-site operation panel installed on-site and can be switched from the above-mentioned operation monitoring control panel.

The large-screen display unit 2f is formed to, for example, 55 inches or more, and is configured to display (play) images/videos (video) of the actual operation (movement) of on-site equipment (actual machines) of mechanical equipment, on-site images/videos (video) required for operation training, etc.

In addition to images and videos of the operation of actual on-site equipment (actual machine), images and videos may also be of a simulation of the actual machine or of the actual operating state of a mechanism similar to the actual machine.

In addition, for example, images and videos captured, for example, on videotape of the operation (movement) of the on-site equipment of the mechanical equipment are stored in the simulation calculation storage unit 2a, and display software is installed that displays (plays) the stored images and videos on the large screen display unit.

Then, by starting operation using the operation monitoring control panel or the on-site operation panel through the display software, a video of the on-site equipment is played on the large screen display unit 2f, and by issuing an instruction from the instructor's calculation and storage unit (instructor panel) 2b to perform an abnormality simulation operation such as stopping the actual mechanical equipment, the video playback is stopped in the same way as the equipment is stopped by the same control as the actual equipment.

The simulation calculation storage unit 2a is also provided with a synchronization device unit (synchronization means) so that, for example, in response to the operation of mechanical equipment, the stored video/images corresponding to the operation can be smoothly displayed on the large screen display unit 2f. The synchronization device unit manages the recording time of the stored video/images, as well as managing and processing the video start time.

In addition, the display software and synchronization device unit allow the recorded video to be switched, such as forward/backward, up/down, right/left rotation, etc., of the mechanical equipment's movements, by operating the instructor panel, the operation monitoring control panel, or the on-site operation panel.

In addition, the playback video displayed on the large screen display unit 2f can be switched by selecting a mechanical training item from the instructor panel.

The display device or the large display device may also have a display means for displaying information on the operating status of the target mechanical equipment in addition to the video/image.

In addition, based on the relationship between the change in the state of the mechanical devices, such as their positions, and the recording time of the video/image of the change in the state of the devices, the amount of change in the state of the devices during a certain playback time of the recorded video (the time from the start of playback to a certain time after the lapse of the recorded video) may be calculated by a calculation means, and the calculated amount of change may be displayed on the display device or large display device as information on the operating state according to the playback time.

For example, when a conveyor device is used to change the state of a drum, such as by moving it along a specified movement trajectory from point A to point B, and a video of the state change, such as the movement from point A to point B, is recorded, the amount of change, such as the movement position (state) of the drum or the ratio to the total movement (total state change), can be calculated by a calculation device from the recording time and the movement along the trajectory (state change) according to the playback time of the recorded video, and the amount of change can be displayed on the display device as information on the operating state.

In addition, for example, when a member is cut or otherwise changed in state by an arc cutting device and a video of the state change from the start of the cut to the completion of the cut is recorded, the amount of change, such as the amount of cut (state) of the member or the percentage of the total cut (total state change), can be calculated by a calculation device from the recording time and the cut (state change) according to the playback time of the recorded video, and the amount of change can be displayed on the display device as information on the operating state.

Traditionally, operational training for mechanical systems has been conducted using actual equipment, which has a high risk of operational errors and damage to equipment. However, according to the present invention, training is conducted using a simulation before operational training on the actual equipment, which makes it possible to prevent operational errors and damage to equipment during operational training on the actual equipment.

2. Description of an example of this system

Since the operation training and maintenance training system of the present invention is configured as described above, operation trainers and maintenance trainers do not conduct operation training and maintenance training independently, but rather conduct operation training and maintenance training while checking with each other in a training room that forms a single area.

First, the operation trainer and maintenance trainer decide on the equipment for operation training and the equipment for maintenance training, make a plan for training using that equipment, and coordinate their schedules (Step 1).

That is, for example, when the equipment to be maintained is decided, the operation trainer decides on operation training for equipment that does not use that equipment, and when the equipment to be operated and trained is decided, the maintenance training for equipment that does not use that equipment is decided, and the operation trainer and maintenance trainer make a plan for training using those pieces of equipment.

Next, the operation trainer and maintenance trainer consider and determine the isolation parts of the equipment based on the equipment determined above (Step 2).

For example, the operation trainer and the maintenance trainer will decide on the content of the isolation based on a comprehensive judgment of the isolation content considered by the operation trainer and the isolation content considered by the maintenance trainer.

Examples of the above isolation include turning off a circuit breaker installed in the wiring, turning off an on-off switch, or unplugging the wiring from the equipment.

Then, before implementing the necessary isolation, the operation trainer and the maintenance trainer confirm with each other verbally or otherwise before isolating (Step 3).

The pre-isolation checks include, for example, checking equipment such as control panels, electrical panels, auxiliary machinery, and valve devices that are subject to maintenance, checking equipment that is subject to operational training, checking whether there is any equipment undergoing maintenance, checking whether there is any equipment undergoing operational training, checking isolation, and checking equipment for which operational training is prohibited.

After completing the pre-isolation checks, the operation trainer and/or maintenance trainer actually perform the isolation (step 4).

The above isolation means may, for example, be a means for cutting off the wiring using a circuit breaker installed in the wiring, or for disconnecting the power wiring from the power output source by, for example, unplugging the connection plug from the outlet, or for turning off an on/off switch installed in the wiring to prevent signals, power, etc. from being transmitted from one side to the other, as well as a means for immobilizing a desired part, such as fixing the opening and closing degree of a valve.

After the above isolation is completed, the operation trainee and maintenance trainee will conduct pre-operation and maintenance training confirmations with each other verbally or otherwise before actually conducting an operation training simulation or performing maintenance on the simulated machine (Step 5).

The pre-operation training/maintenance training checks include, for example, checking whether the above-mentioned isolation has actually been carried out, checking the simulated machine that is the subject of maintenance training, checking the equipment for operation training, checking whether there is a simulated machine undergoing maintenance, checking whether there is equipment undergoing operation training, and checking the simulated machine for which operation training is prohibited.

After completing the above operation training and maintenance training confirmation, the operation trainee will actually use the operation training simulation device to operate and monitor the actual machine (simulated machine). In addition, the maintenance trainee will perform maintenance training such as isolation work, disassembly work, cleaning work, repair work, and assembly work for the corresponding simulated machine (step 6).

Then, after the operation and maintenance training, the operation trainer and the maintenance trainer verbally or otherwise confirm with each other that the training has been completed, and whether or not isolation will be restored (step 7).

After confirming that the training has been completed, the operation trainer and/or maintenance trainer restores the system isolation (step 8).

After the isolation is restored, the operation trainer and the maintenance trainer verbally or otherwise confirm with each other whether the isolation has been restored (step 9).

These checks may include, for example, checking whether the isolation has actually been restored, whether tests have been conducted to check whether the equipment actually works, and the details of subsequent training, etc.

After confirming that the isolation has been restored, the operation trainer may, for example, conduct operation training that includes the simulated machine that was the subject of maintenance. Note that before conducting this operation training, the maintenance trainer should again orally confirm the operation training content, isolation status, maintenance status, etc., in the same manner as described above.

It is also possible to omit some of the above confirmation steps.

The operation training simulation device 2 may acquire the operating status and maintenance status (information) of the simulator via the wiring and display the information on a display device or the like of the operation training simulation device 2 so that the operation trainee can understand the information. The operation training simulator device 2 may then perform operation training according to the maintenance status of the maintenance training simulator.

In addition, the operation of the equipment related to the operation training simulation device 2 may be prevented based on the operating status and maintenance status of the simulator, and this information may be displayed on the display device, etc., so that the operation training simulation device 2 can perform operation training according to the maintenance status of the maintenance training simulator.

In addition, the operating status of the operation training simulation device 2 may be displayed on the large screen display device 2f or a separately provided display device, so that the operating status can be understood by the maintenance trainee, and the maintenance training simulator may perform maintenance training according to the operating status of the operation training simulation device.

In addition, an alarm device such as a buzzer may be provided on equipment related to the operation of the driving training simulation device, so that the buzzer sounds to warn if maintenance is about to be performed during operation.

As described above, operation trainers and maintenance trainers will check with each other as they proceed with the work.

3. Explanation of specific examples of implementation of this system

(1) Example of maintaining the control panel simulator 3

(a) The operation trainer and the maintenance trainer decide on the equipment for operation training when maintaining the control panel simulator 3, for example, decide on operation training using only the operation training simulation device 2, make a plan for training using that equipment, and coordinate their schedules.

(b) Next, the operation trainer and maintenance trainer review the isolation parts of the equipment and decide that, for example, as shown in FIG. 3, the operation trainer will shut off the circuit breaker 18 on the control panel simulator 3 side of the power supply wiring 16, shut off the circuit breaker 19 on the power supply source 15 side, turn off the on/off switch parts of the signal wiring (signal cables) 24, 26 connecting the control panel simulator 3 and the electrical panel simulator 4, and isolate the equipment by turning off a cable lift.

(c) Then, before carrying out the above isolation procedures, the operation trainer and the maintenance trainer will verbally or otherwise confirm with each other that they will carry out each isolation procedure.

(d) After the above confirmation, the operator trainee will isolate the above equipment.

(e) When isolation is complete, the operation trainer shall inform the maintenance trainer, verbally or otherwise, that isolation has been carried out. The maintenance trainer shall then confirm whether the equipment has actually been isolated and inform the operation trainer, verbally or otherwise, of the same.

(f) Then, the operation trainee performs operation training using only the operation training simulation device 2, and the maintenance trainee performs maintenance such as inspection of the control panel simulator 3.

(g) After the operation and maintenance training, the operation trainer and the maintenance trainer will verbally or otherwise confirm with each other that the training has been completed and whether or not isolation will be restored.

(h) After confirming this, the trainee will restore the isolated portion.

(i) Then, after the isolation is restored, the operation trainer will inform the maintenance trainer verbally or otherwise of the restoration, and if necessary, the maintenance trainer will confirm the restoration status by testing the equipment, etc., and they will communicate with each other verbally or otherwise.

(j) Then, if necessary, the driver trainee will conduct driver training that also includes the control panel simulator 3.

(2) Example of maintaining electrical panel simulator 4

(a) When maintaining the electrical panel simulator, the operation trainer and the maintenance trainer decide on operation training using equipment other than the parts related to the electrical panel simulator 4, for example as shown in FIG. 3, make a plan for training using that equipment, and coordinate each other's schedules.

(b) Next, the operation trainer and the maintenance trainer review the isolation parts of the equipment and decide that, for example, as shown in FIG. 3, the operation trainer will isolate the equipment by disconnecting the signal wiring 24, 26 and the circuit breaker 30 installed on the power supply wiring 14 of the operation unit 20 of the valve device simulator 6.

(c) From then on, just as in the example of maintaining the control panel simulator, the operation trainer and the maintenance trainer will proceed with the training while confirming with each other verbally, etc.

(3) Example of maintaining the valve gear simulator 6

(a) When maintaining the valve gear simulator, the operation trainer and the maintenance trainer decide on operation training using equipment other than the parts of the electrical panel simulator 4 related to the valve gear simulator 6, as shown in FIG. 3, for example, and plan the training using that equipment and coordinate their schedules.

(b) Next, the operation trainer and the maintenance trainer review the isolation parts of the equipment and decide, for example, as shown in Figure 3, that the operation trainer will isolate the disconnection of the circuit breaker 30 installed on the power supply wiring 14 of the operating part of the valve device simulator 6.

(c) From then on, just as in the example of maintaining the control panel simulator, the operation trainer and the maintenance trainer will proceed with the training while confirming with each other verbally, etc.

As shown in FIG. 2, the mode changeover switch unit 28 may be switched from the wiring 22, 24 of the valve gear simulator 6 to the simulation unit 27, so that the trainee can train in operation of the valve gear simulator 6 in a simulation.

Since it is not normally used, it is used to check whether operation trainers and maintenance trainers are sharing information.

4. Description of other embodiments of this system

Figure 4 is an example of the operation training simulation device 2. For example, an actual plant (actual machine) of a nuclear fuel cycle facility is composed of actual machines V01, V02, and V03 in the simulation, and one end of a transfer pipe a is connected to the actual machine V01, and a branch pipe c1 and a branch pipe c2 are provided branching from the other end b of the transfer pipe a, and the other end of the branch pipe c1 is connected to the actual machine V02, and the other end of the branch pipe c2 is connected to the actual machine V03.

In addition, a connecting pipe e is provided to connect the actual machine V01 and the intermediate portion d of the transfer pipe a, and parallel pump devices P01 and P02 are inserted in parallel into the connecting pipe e.

In addition, a valve device W001 is interposed between the actual machine V01 and the intermediate portion d of the transfer pipe a, a valve device W002 is interposed between the intermediate portion d and the other end portion b of the transfer pipe a, and valve devices W003 and W004 are interposed in the branch pipes c1 and c2, respectively.

In the above simulation device, before conducting operation training on the actual machines V01 to V03, the operation trainer performs a pre-operation check, for example by verbally confirming with the maintenance trainer whether there are any devices or control panels under maintenance.

For example, if it is determined that valve device W001 is undergoing inspection, the trainee operator will decide to isolate the parts related to valve device W001, for example by prohibiting mixing operations of actual device V01 and transfer operations from actual device V01, thereby isolating them.

Isolation may also be performed by maintenance trainers.

In addition, instead of or in addition to verbally contacting the maintenance trainer, the operation trainer may, for example, check information from a detection device provided in the operation training simulation device 2 that detects whether or not maintenance is required for the simulator.

Then, if necessary, the operation trainer or maintenance trainer will be notified that the isolation is complete, and after that, the operation trainer will conduct operation training for the actual units V02 and 03.

In addition, before performing maintenance on the above-mentioned equipment, valve devices, etc., the maintenance trainer will, for example, verbally inform the operation trainer of the equipment, valve devices, etc. that will be maintained and conduct a pre-maintenance training check.

For example, when maintenance is performed on the valve device W001, a notice of this fact, or a notice of prohibition of mixing operations of the actual device V01 related to the valve device W001 and transfer operations from the actual device V01, etc., will be sent and isolation will be performed.

In addition, maintenance trainers will isolate the simulated aircraft if necessary.

In addition, for example, the large display device may be configured to show the operating status of the driver training simulation, and instead of or in addition to verbal communication, the large display device may be used to check that something is in operation and not perform maintenance.

Then, the operation trainer or maintenance trainer is notified that the isolation is complete, and after that, the maintenance trainer performs maintenance on the actual machine V01.

5. Explanation of other examples of the large screen display unit 2f of this system

Another embodiment of the large screen display unit 2f is to use two or more large screen display units 2f (large display boards), for example, three large display boards. The size of the large screen display unit 2f (large display board) is not particularly limited, but to make it easy to see, it is, for example, 40 inches or more and 100 inches or less, preferably 55 inches or more and 80 inches or less.

Each large display panel will display, for example, the operating status of electrical equipment, ventilation and air conditioning equipment, solution transfer and reception, safety system auxiliary equipment, etc.

The display on each large display panel can be changed at will by trainees, etc.

In this way, by using multiple large display panels, it is possible to simultaneously display the main systems and processes required for the plant's purpose (e.g., power generation) even in plants (processes) that cannot be displayed together.

Even if it is possible to display everything together on one display, using multiple large display panels makes it easier to use.

If an abnormality occurs in the plant, for example, the two large display panels will display an enlarged screen showing the operation monitoring status of the plant where the abnormality occurred as one screen, and the other large display panel will automatically switch to display, for example, the circumstances under which the abnormality occurred and the status in text.

In this way, when an abnormality occurs, different display methods can be used on each large display panel, making it possible to immediately identify the abnormal condition.

In addition, all information regarding abnormalities can now be displayed on a single large display panel.

Figure 5 shows an example using three large display panels 35a, 35b, and 35c.

Under normal conditions when there are no abnormalities, each of the large display panels 35a, 35b, and 35c will display, for example, (1) an electrical equipment screen, (2) a ventilation and air conditioning equipment screen, and (3) a solution transfer/receiving and safety system auxiliary equipment operation screen.

In addition, each of the large display panels 35a, 35b, and 35c is provided with, for example, a common display section 36, an operating status screen display section 37, and an operating status character display section 38.

The common display units 36 may display, for example, the date and time, an alarm, or guidance.

The operation status screen display unit 37 also displays, for example, an operation monitoring screen for electrical equipment, an operation monitoring screen for building ventilation equipment, an operation monitoring screen for solution transfer/receiving, safety equipment, and BO sequence, as well as an overall screen that simultaneously displays all of these screens.

For example, when the operation monitoring screen for solution transfer/receiving, safety equipment, and BO sequence is displayed on the operation status screen display unit 37, the operation status character display unit 38 will display, for example, "F1 ACM (MCM)," "F2 ACM (MCM)," "F1-1 Mixing operation (stopped)," "F1-1 Mixing operation completed," "F1-2 Transfer operation (stopped)," etc.

In addition, for example, when the operation monitoring screen of the building ventilation equipment is displayed on the operation status screen display unit 37, the operation status character display unit 38 displays, for example, "Building blower automatic (manual)", "Building blower selection A, B, C operation/D standby (A, B, D operation/C standby, A, C, D operation/B standby, B, C, D/A standby, reset)", "Building exhaust fan I selection A, B, C operation/D standby (A, B, D operation/C standby, A, C, D operation/B standby, B, C, D/A standby, reset)", "Building exhaust fan II selection A, B, C operation/D standby (A, B, D operation/C standby, A, C, D operation/B standby, B, C, D/A standby, reset)", and "Building exhaust fan III selection A, B, C operating/D standby (A, B, D operating/C standby, A, C, D operating/B standby, B, C, D/A standby, reset) etc. will be displayed.

In addition, when, for example, an operation monitoring screen for electrical equipment is displayed on the operation status screen display unit 37, the operation status text display unit 38 will display, for example, "Receiving power from DA-M/C-C GC building (not receiving power)," "Receiving power from DA-M/C-D2 GC building (not receiving power)," "Receiving power from DA-M/C-C M/C-D2 (not receiving power)," "Receiving power from DA-M/C-D2 M/C-C (not receiving power)," etc.

When an abnormality occurs, for example, large display panels 35a and 35b will display a screen showing the abnormal operating status of the electrical equipment or building ventilation equipment where the abnormality occurred, and large display panel 35c will automatically switch to display in text the abnormality occurrence status and condition, such as the current time, the time when the abnormality occurred, and the abnormality display.

As another example of when an abnormality occurs, as shown in FIG. 6, for example, large display panel 35a displays a screen showing the abnormal operating status of the solution transfer/receiving or safety auxiliary equipment where an abnormality has occurred, large display panel 35b displays a more specific abnormality location, and large display panel 35c automatically switches to display text indicating the abnormality occurrence status and condition, such as the current time, the time when the abnormality occurred, and the abnormality display.

The common display unit 36, the driving status screen display unit 37, and the driving status character display unit 38 may each be omitted as necessary.

6. Effects of this system

In the operation training and maintenance training system of the present invention, a single training room is equipped with the simulator device for operation training, a control panel simulator for maintenance training, an electrical panel simulator for maintenance training, and an auxiliary equipment and valve device simulator for maintenance training, making it possible to provide a compact operation facility.

In addition to traditional training, it will also be possible to conduct training such as checking plant operation status and maintenance work status, which was not possible with traditional training.

In addition, trainees can now actually see and confirm that control panels, auxiliary machinery, valve devices, and other equipment that they have never seen before are controlled by the control panel through operational control and that the equipment operates.

In addition, maintenance trainees can now practice starting maintenance only after confirming that there are no problems with the operating condition.

In addition, maintenance trainers can now also carry out isolation training for the connecting members that connect the operation training simulation device 2 and the maintenance training simulator, and isolation training for the connecting members that connect the maintenance training simulators to each other.

As a result, it is now possible to conduct training that was not previously possible, such as "isolation work training" that should be conducted by operation trainers, "isolation status confirmation training" that should be conducted by maintenance trainers, and "job (schedule) coordination training between operation trainers and maintenance trainers."

In addition to the traditional operation training, operation trainees can simultaneously acquire knowledge about the general outline of maintenance work that they need to know, and maintenance trainees can simultaneously acquire knowledge about the general outline of operating facilities that they need to know, enabling early training of young engineers and maintenance personnel.
