[0001]
BACKGROUND OF THE INVENTION
The present invention relates to operation training simulator system for training definitive maneuvering set Bei driving operation.
[0002]
[Prior art]
Conventionally, an operation training simulator device has been used to train operation operations in plant facilities such as ship handling facilities, power generation facilities, and dam facilities (including small plant facilities such as pump operations only in this specification). ing. In this operation training simulator device, a complex operation during actual operation is trained in advance by performing a simulated experience of the same operation before operating the actual plant equipment. Recent plant facilities often involve complicated operations, and various operation training simulators have been developed.
[0003]
For example, the invention described in Japanese Patent Laid-Open No. Hei 6-282220, which is this type of prior art, outputs a simulated sound that changes according to weather conditions, a gate operating sound accompanying a gate operation, and a gate discharge sound. A simulator for dam operation training that gives a close sense of realism and tension and realizes effective training is described (conventional example 1).
[0004]
In addition, in the invention described in Japanese Patent Laid-Open No. 2-43591, which is another prior art, an acoustic simulation method for outputting a sound related to the display contents of a CRT when a simulation result for the simulator device is displayed on a CRT display. Is described (conventional example 2).
[0005]
Furthermore, the invention described in Japanese Patent Application Laid-Open No. 8-24027 includes a plant operation training simulator that provides trainees with still images, moving images, and audio information that give a sense of presence similar to operating an actual operation panel. It is described (conventional example 3).
[0006]
Further, in the invention described in Japanese Patent Laid-Open No. 9-212076, there is provided a training simulator that displays an image indicating the state of the equipment related to the training event on the display device and causes the sounding device to generate a sound effect indicating the state of the equipment. (Conventional example 4).
[0007]
[Problems to be solved by the invention]
However, the conventional example 1 converts switch information such as a gate operation into contact information, and selects and outputs a preset simulated sound and volume level based on the contact information. The combination of simulated sounds to be played is determined, and it is difficult to obtain a sense of reality according to the actual operation.
[0008]
Also, in the conventional examples 2, 3, and 4, only a specific sound effect prepared in advance is selectively reproduced in accordance with the operation of the trainee, and it is possible to obtain a sense of realism according to the actual operation. Have difficulty.
[0009]
That is, in these conventional techniques, only the sound effect prepared in advance is reproduced at a predetermined volume when the operation device is turned on / off, and the output is only on / off. Therefore, various situations (changes in sound) that occur when operating actual plant equipment cannot be accurately reproduced, and a sufficient effect can be obtained as an operation training simulator device for training optimal operations. Is difficult.
[0010]
[Means for Solving the Problems]
Therefore, in order to solve the above-mentioned problem, the present invention is an operation training simulator device for training the operation operation of the cargo handling pump in the marine vessel maneuvering equipment, in which various sound effects corresponding to the cargo handling pump are stored in advance.

Instructing means to instruct trainers is provided. By configuring in this way, the sound effect output according to the physical quantity calculated according to the operation of the trainee is changed, and the sound effect of the phenomenon that occurs according to this changing physical quantity is synthesized in real time ( (Overlapping) and output. Thereby, the physical quantity change by the operation of the trainee is reflected in the reproduction speed and volume of the sound effect, and training with a high sense of reality is possible.
[0011]
Moreover, the calculation of the frequency component that filters the various sound effects from the operation of the trainee and the calculation of the output frequency component of various sound effects and the synthesis based on the calculation results are performed on separate computers, so that it is possible to simplify the computer program, cut with forming an operator training simulator apparatus installed a calculator in separate locations.

Further, it is possible to call attention by voice announcement to the operation of the training personnel, and possible early acquisition of operations.
[0013]
Furthermore, it is possible to cope with appropriate voice announcements in accordance with an operation status of the training personnel.
[0014]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a configuration diagram of a driving training simulator apparatus showing an embodiment of the present invention, FIG. 2 is a schematic diagram for explaining a sound effect filter operation in the driving training simulator apparatus, and FIG. 3 is the driving training simulator. It is a schematic diagram for demonstrating synthetic | combination effect of the sound effect in an apparatus .
[0015]
As shown in FIG. 1, the driving training simulator apparatus 1 includes a main computer 2, a reproduction computer 3 (including a storage device and a sound synthesizer), a voice instruction CRT 4, and a speaker 5. The storage device of the computer 3 for reproduction includes a sound effect data storage unit 6 and a sound announcement data storage unit 7. The sound effect data storage unit 6 and the sound announcement data storage unit 7 include various sound effect data and sound announcement data. Is stored in advance. The sound effect data is determined according to the plant equipment, for example, cargo handling pump sound, cavitation sound, water hammer sound, and the like. As voice announcement data, there are notifications of abnormalities that do not appear on the operating equipment such as “pump sound is abnormal”, instruction announcements such as “Please reduce the number of revolutions”, and the like. These various sound effect data may be recorded actual operation sound or may be artificially created. The speaker 5 is an output device.
[0016]
Moreover, in this embodiment, since the driving training simulator apparatus for training the driving operation in the boat maneuvering equipment is taken as an example, a console 8 for maneuvering is provided. The console 8 is provided with an operation lever, an operation button, and the like for performing actual ship maneuvering, and is configured such that a signal is input by an input operation of the trainer 9. The input operation of the trainer 9 includes, for example, a switch operation for starting a cargo handling pump and an operation such as pump speed control.
[0017]
In the main computer 2, a physical quantity is calculated from a mathematical model in accordance with a physical formula in accordance with the operation of the trainee, and a necessary value and an operating state of the device are transmitted to the reproduction computer 3 from the result.
[0018]
In the reproduction computer 3 (acoustic synthesizer), when the physical quantity is within a certain range by the operation of the trainee, the reproduction flag of the assigned sound effect is turned ON. The sound effect for which the reproduction flag is turned on is output by filtering the stored sound effect according to a change in physical quantity by filtering a frequency component in a specific range. As a method of applying this filter, a filter is applied to a specific frequency component in accordance with a change in physical quantity (for example, ON / OFF of a switch, movement of a lever, etc.) that is changed by a trainee's device operation to a reference sound effect. Over time, the operation of the trainee is dynamically reflected in the sound effect. For example, the frequency to be filtered = f (physical quantity).
[0019]
As an actual device, if the input operation of the trainer 9 is tilting of the operating lever for controlling the rotational speed of the pump, the operation amount is calculated from the tilting direction and angle, and the rotational speed of the pump is calculated from the calculation result. The calculated sound effects are filtered according to the number of rotations, and the sound effects that are made larger or smaller are output (FIG. 2: details will be described later). Also, depending on the situation, the speed of sound effect playback is increased or decreased to always reflect changes in physical quantities due to the operation of the trainee 9 by calculation. Examples of the filter for the sound effect include a change in sound quality, a change in volume, and a change in reproduction speed. This processing can be performed by software or dedicated equipment.
[0020]
In this embodiment, a voice instruction CRT4 is provided. When an instruction is output from the voice instruction CRT4, the reproduction flag of the voice announcement data is turned ON. When the reproduction flag is turned ON, the assigned voice announcement data is output. This voice announcement data is also processed by the playback computer 3, and data assigned from the data stored in the voice announcement data storage unit 7 is played back.
[0021]
As a result of such processing, when a plurality of flags are turned ON, sound effects are superimposed on the reproduction computer 3 and output (FIG. 3: details will be described later). This process is also performed by software or a dedicated device.
[0022]
Hereinafter, a specific operation when the cargo handling operation of the oil tanker ship is trained will be described. The case where the pump for cargo handling is started as an input operation of the trainee 9 to the console 8 will be described. Along with this, a start signal for the cargo handling pump is sent from the simulator main computer 2 to the regeneration computer 3.
[0023]
In the regeneration computer 3, a predetermined (pump regeneration sound) regeneration flag is turned ON by a pump start signal. This reproduction computer 3 also serves as an acoustic synthesizer (performed by software). When the reproduction flag is turned on, the frequency component range to be filtered is determined by the number of rotations of the pump, and a reference sound effect (for example, , Which is a reference waveform recording the operating sound of the actual machine), and then output.
[0024]
FIG. 2 shows an example in which the waveforms are different depending on whether the rotational speed of the pump is large or small. For example, when the rotation speed is high, the loudness (usually “decibel”) is increased, and the pitch (usually “hertz”) is increased. When the rotation speed is low, the loudness is increased. The pitch (usually “decibel”) is reduced and the pitch (usually “hertz”) is lowered. By calculating the rotation speed of the pump from the physical quantity that changes according to the operation of the trainee in this way, by filtering the sound effect that becomes the reference according to the rotation speed, and outputting the sound effect that is increased or decreased, A sense of reality that changes according to the amount of operation by the trainees is obtained. These waveforms are merely examples, and it is only necessary to appropriately determine how to apply the filter according to the use conditions.
[0025]
On the other hand, the range of frequency components to be filtered changes in real time depending on the rotational speed of the pump. For example, as shown in the upper part of FIG. 3, when the physical quantity increases and enters the range of the pump cavitation phenomenon during operation of the cargo handling pump started by the trainee, the effect of cavitation is obtained as shown in the middle part. The sound reproduction flag is turned on.
[0026]
The cavitation sound effect (artificially created) is output after determining the range of the frequency component to be filtered by calculating the degree from the NPSH curve and applying the filter. At this time, as shown in the lower stage, the sound effect of the cavitation is superimposed on the sound effect of the cargo handling pump in real time and output.
[0027]
After that, as shown in the upper part, when the physical quantity is out of the range of the cavitation phenomenon by the operation of the trainee, the cavitation sound effect regeneration flag is turned off and only the operation sound of the cargo handling pump is output as shown in the middle part. .
[0028]
The sound effect output at this time is changed in real time from the state in which the sound effect of the cavitation is superimposed on the sound effect of the cargo handling pump to only the sound effect of the cargo handling pump, as shown in the lower part.
[0029]
In this way, the sound effect of the phenomenon (cavitation) caused by the physical quantity (pump rotation speed) that is changed by the operation of the trainee is synthesized and output in real time. The horizontal axis in FIG. 3 shows the passage of time. In this example, only the sound effect of cavitation has been described. However, due to a change in the pump rotation speed, for example, a high-frequency sound is emitted when the rotation speed increases, and a high-frequency sound is canceled when the rotation speed decreases. Done. At this time, the tone color may be changed by superimposing other sound effects.
[0030]
In this embodiment, the voice instruction CRT4 is provided so that an appropriate warning instruction can be simultaneously given from an instructor or the like if there is an erroneous operation when the trainee is training while having a sense of reality. . That is, even when the situation is sequentially changing as described above, if voice announcement data output is instructed by the voice instruction CRT4 during the output of the sound effect, the sound announcement data is superimposed on the sound effect and output. In this way, it is possible to maintain a sense of reality as if an actual plant facility is being operated, and at the same time to respond immediately to an erroneous operation. As a result, it is possible to perform extensive training in a short period of time.
[0031]
As described above, according to this driving training simulator device 1, it is possible to filter and output a specific frequency component of a reference sound effect in accordance with a change in physical quantity that changes due to operation of equipment in the simulator. The operation of the trainee can be dynamically reflected in the sound effect. At the same time, it is possible to synthesize sound effects of phenomena that occur in response to changes in physical quantities caused by trainee operations in real time, or to output multiple sound effects and voice announcement data at the same time. It is possible to provide highly realistic training and advice on appropriate judgment by the trainees at the same time.
[0032]
In other words, since the frequency of the sound effect output is changed according to the physical quantity change caused by the trainee's equipment operation, the operation that changes according to the training process is reflected in the sound effect in real time, and the plant equipment is actually operated. This makes it possible to train with a high sense of reality while having a sense of tension.
[0033]
In the above embodiment, although the operation training simulator apparatus 1 in the plant of a materials handling facility of the oil tanker the description, such operation training simulator apparatus 1 may be employed in other plant equipment.
[0034]
For example, in the case of a dam plant facility, changes in the sound of wind and rain, changes in the discharged water sound due to the change, gate opening / closing sounds made by the trainee, etc. are synthesized and output. When the sound volume is increased or the sound quality is changed and the normal operation returns to the steady operation state, the sound is returned to the normal sound.
[0035]
In the case of a pressure vessel control plant facility, if the pressure inside the vessel increases due to incorrect operation of the on-off valve, etc., a high-frequency sound is output and an abnormal sound effect is output, and if the pressure inside the vessel decreases due to normal operation. Gradually lower the high frequency sound and return to normal sound when steady pressure is reached.
[0036]
The above-described embodiment is an embodiment, and various modifications can be made without departing from the gist of the present invention. The present invention is not limited to the above-described embodiment.
[0037]
【The invention's effect】
The present invention is implemented in the form described above, and has the following effects.
[0038]
Since the sound effect output according to the physical quantity calculated according to the operation of the trainee is changed, the change in the physical quantity due to the operation of the trainee is reflected in the sound effect, and training with a high sense of reality is possible.
