Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a training evaluation apparatus for a ship-handling simulator, and more particularly to a training evaluation apparatus capable of objectively evaluating the judgment ability of trainees.

[0002]

2. Description of the Related Art Generally, as a device for learning the skill of manipulating a ship, a ship maneuvering simulator is known which creates a ship maneuvering environment close to an actual ship and conducts training on land.
Such a ship-handling simulator can perform dangerous training and repetitive training that cannot be performed on an actual ship, and is extremely useful for ship-handling training.

[0003] Conventionally, a ship maneuvering simulator has been equipped with a full-size simulated bridge imitating an actual bridge, and a maneuvering trainee checks the main engine and the rudder while checking the marine vessel maneuvering status with the instruments in the simulated bridge. Do the operation. In addition, in order to provide highly realistic training, a simulated view image from a real ship such as a port scenery or another ship is projected in front of the simulated bridge where the trainees board, and it was installed inside the simulated bridge. From the speaker, engine sound, wind noise, wave sound, steam whistle and fog whistle of other ships are emitted.

[0004]

[Problems to be Solved by the Invention] By the way, recent marine traffic is becoming more and more congested. Along with this, trainees are required to acquire more advanced control skills, and it is also necessary to objectively and accurately evaluate the actions taken by trainees during training. In this respect, the conventional ship-handling simulator is insufficient, and only evaluates the trainee's steering ability. In other words, simply by evaluating the ability to operate the rudder based on the amount of deviation (distance, course) from the instruction course of the training ship, for example, "What kind of judgment (training) did the trainee make when he / she sensed a danger?" It is impossible to evaluate the judgment ability of trainees such as "No?"

The present invention has been made in view of the above circumstances, and an object thereof is to provide a training evaluation apparatus for a ship-handling simulator capable of objectively and accurately evaluating the judgment ability of a trainee. is there.

[0006]

In order to achieve the above-mentioned object, the present invention is designed for each assumed ship operation situation in a ship operation simulator for operating a simulated bridge while watching another ship or the like in the view. A memory for storing an evaluation function that defines the output relationship and a means for judging the maneuvering situation at any time based on the relationship between other ships that change due to the operation of the above-mentioned simulated bridge, and a means for responding to each of the judged maneuvering situations And a means for evaluating the training ability of the trainee based on the evaluation function.

[0007]

According to the present invention, since the marine vessel maneuvering ability of the trainee can be evaluated for each marine vessel maneuvering condition determined based on the relationship with another ship, in addition to the trainee's steering ability under normal marine vessel maneuvering conditions,
It is also possible to objectively evaluate the judgment ability in a situation where some judgment such as risk avoidance is required.

[0008]

Embodiments of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 shows a schematic configuration of a ship maneuvering simulator 11 according to this embodiment. In the figure, 12
Is a life-size simulated bridge for trainees to board and conduct training training. Inside the simulated bridge 12, a full-scale steering device, a main engine control device, navigational instruments and the like are provided. When the trainee operates the rudder and the main engine, a steering signal and an engine telegraph signal indicating the operation amount. Is transmitted to the simulator main computer 14. In addition, 13 is an instructor's desk for setting conditions necessary for training such as training scenarios, types of training ships, training areas, environment, etc. The conditions to be set from various menus displayed on the display are set by the mouse. It can be selected according to the requirements. A signal regarding the training condition set in the instructor desk 13 is also transmitted to the simulator main computer 14.

The simulator main computer 14 is the simulated bridge 1
2 and the instructor's desk 13 based on signals from the training table to simulate the motion of the training ship, and calculate the position, speed, acceleration, etc. of the ship (training ship) in the training area in real time, and the navigation instrument inside the simulated bridge 12 Control the kind. Further, the navigation data calculated by the motion simulation calculation is appropriately transmitted to the visual field simulation device 15 and the acoustic simulation device 16. The visibility simulating device 15 is a visual image from the actual ship based on the position data of the own ship in the training area (the actual port operator's view of the port, etc.)
Is created by CG and is enlarged and projected through a video projector 18 onto a screen 19 provided in front of the simulated bridge 12. The acoustic simulation device 16 is a position from the main computer 14,
Engine sound based on data such as speed and engine speed,
The speaker 20 reproduces wind noise, sound of waves, etc. and synthesizes them.
Output from.

The simulator main computer 14 further has a relative positional relationship (distance, azimuth angle, heading angle, etc.) between the own ship and another ship when another ship (another ship) is present in the training area.
Is calculated and output to the training evaluation device 21 as data for training evaluation at any time. The training evaluation device 21 is mainly configured by a microcomputer including a CPU 22 and a memory 23, and the CPU 22 operates based on a program stored in the memory 23 in advance. Here, the CPU 22 determines the situation of the trainee for each situation determined by the situation determination unit 22a and the situation determination unit 22a that determines the marine vessel maneuvering condition (normal time, escape time, etc.) from the relationship with other ships, depending on the mode of operation. Ship maneuvering evaluation unit 22b and ship maneuvering evaluation unit 22 that evaluate the actions taken
It has a display control unit (not shown) for displaying the evaluation result in b on the display of the instructor's desk 13.

That is, in the memory 23 built in the training evaluation device 21, in addition to the operation program (FIGS. 2 to 7) described later, the evaluation function prepared for each item to be evaluated in each of the assumed ship maneuvering situations is used. It is stored in association with the situation. Here, the evaluation function defines the relationship between the input value (variable) and the output value (score). For example, as shown in FIG. 8, a line function with the horizontal axis as input and the vertical axis as output is used. be able to. When the positional relationship data is input from the main computer 14, the CPU 22 stores these data in the memory 23. Then, the situation determination unit 22a predicts the risk of collision with another ship, and if there is a danger of collision, it is determined that the situation is "avoidance vessel maneuvering situation for avoiding a collision", and if not, "normal vessel operation situation". It is determined to be in. Also, once it is judged that there is a collision avoidance situation, it is judged that the situation is "corrected vessel maneuvering situation for correcting course deviation due to escape". After the marine vessel maneuvering situation is determined in this way, the marine vessel maneuvering evaluation unit 22b calls an evaluation function corresponding to the marine vessel maneuvering situation from the memory 23, and
Select an appropriate value from the positional relationship data as an input value and score it. That is, during the training, whether or not the action taken by the trainee in each ship maneuvering situation is appropriate is objectively scored against the evaluation function.

Next, the operation of the training evaluation device 21 will be described. FIG. 2 shows a flowchart for explaining the operation of the training evaluation device 21.

When the marine vessel manipulating training is started and the positional relationship data, the navigation data and the marine vessel maneuvering signal are input to the training evaluating device 21, the training evaluating device 21 first determines the current state of the own ship (step 100). ), And then determine the maneuvering status based on the relationship with the other ship (step 200). Here, in the condition determination of the own ship in Step 100, as shown in FIG. 3, the turning angular velocity of the own ship is determined (Step 101), and if it exceeds zero, it is set that the vehicle is turning to the right (Step 101). 104), if not exceeded, set that the vehicle is turning left (step
102). If it is exactly zero, it is set to go straight (step 103). Then, if there is no change in the set turning state, the cumulative turning angle is further calculated (steps 105 and 106).
If there is a change, the cumulative turning angle is reset (step 107). After that, if the ship is proceeding, the acceleration is judged (step 109), and either deceleration, constant speed, or acceleration is set (steps 110 to 112), and then the main rule of FIG. 2 is entered. Return. On the other hand, in the step 200, for determining the relationship with the other ship, as shown in FIG. 4, it is determined whether or not the other ship is within the warning radius of the own ship (step 201). It is determined that "there is", and the normal mode is set (step 206). If another ship is within the warning radius, the prediction function determines the risk of collision (step 202,
203), if it is judged that there is a risk of collision, it is judged that "the ship is in the avoidance maneuvering situation for avoiding the collision" and the escape mode is set (step 207). After setting the escape mode, further set a matchmaking relationship with another ship (steps 209, 210). If it is determined in step 203 that "there is no risk of collision", it is determined whether the previously set mode is the escape mode (step 204), and if it is not the escape mode, "there is no risk of collision even if another ship is nearby. The normal mode is set as `` no '' (step 206), but if the escape mode has already been set, the corrected marine vessel maneuvering condition to correct the course deviation caused by the escape route if the danger of collision has disappeared. Set the post-evacuation correction mode as "in" (step 208).

When the marine vessel maneuvering condition mode is set as described above, the training evaluation device 21 then returns to the main rule of FIG. 2 to determine what mode has been set.
(Step 300), one of the ship maneuvering evaluation programs prepared in advance for each maneuvering situation is selected and executed (Step 400
~ 600). Here, in the normal ship maneuvering evaluation program of step 400, the deviation (distance and angle) of the ship from the initially planned course is calculated, and the steering ability of the trainee is evaluated based on this. Further, in the avoidance maneuvering evaluation program of step 500, the judgment ability (coping ability) of the trainee is evaluated by determining what kind of action was taken at the time of avoidance. In addition, the modified vessel maneuvering evaluation program in step 600 determines what course return action was taken after evasion, and the trainee's ability to return to the course is evaluated based on the effect (whether a new danger has occurred, etc.). .

After the training maneuvering ability of the trainee is evaluated as described above, the training evaluation device 21 determines whether or not the training is completed (step 700), and if the training is completed, the evaluation operation is also completed. However, if the training is continued, the process returns to step 100 and the above situation determination and evaluation are repeated.

FIG. 5 shows a specific example of the avoidance vessel maneuvering evaluation program (step 500) as an example of the marine vessel maneuvering evaluation program (steps 400 to 600 in FIG. 2). In this sub-rule, first, it is judged what kind of relationship has been set (step 501), and if it is "end-to-end," it is evaluated according to the "end-to-end ship handling evaluation program" (step 504), and "cross-cut". If so, after further determining whether or not the own ship is a holding ship capable of holding a course (step 502), the ship is evaluated according to the "traverse holding ship marine vessel maneuvering evaluation program" or the "traverse crossing escape ship maneuvering evaluation program" (steps 505, 506). ). When the judgment result in step 501 is "overtaking", the evaluation is performed according to the "overtaking maneuvering evaluation program" or the "overtaking maneuvering evaluation program" depending on whether the own ship is the holding ship (steps 503, 507, 508).

FIGS. 6 and 7 show a specific example of the above-mentioned "traffic avoidance vessel maneuvering evaluation program (step 506 in FIG. 5)". If it is determined that a evasion operation is required for a crossing ship, it is first determined whether or not there is an evasion maneuvering operation (step 506.1), and if there is a maneuvering operation, that operation is the first evasion operation. Determine (step 506.3). If the vessel maneuvering operation is the first evasion operation, it is scored as "Is the evasion start time appropriate?"
506.4), and further, "Is the amount of operation of changing the needle appropriate?" And "Is the amount of shift operation appropriate?" (Steps 506.9, 506.10). Also,
If the evasion maneuvering operation is the second or later one, only "Is the amount of change in needle operation appropriate?" And "Is the amount of gear change operation appropriate?" After scoring each evaluation item in the initial stage of the escape operation in this way, it is judged whether or not the escape operation has ended.
(Step 506.11) If it is completed, the escape operation is evaluated (Step 506.12), and if it is not completed, it waits. In the evaluation of evasion action (step 506.12),
As shown in FIG. 7, "Is the passing distance appropriate?", "Is the passing position appropriate?", "Is the number of course changes appropriate?", "Is the number of speed changes appropriate?"

If there is no vessel maneuvering operation or there is no change in the operation itself even if evasion is required (when the results of steps 506.1 and 506.2 are NO), the evasion start time, the amount of needle change operation and The evaluation items of the shift operation amount are not scored, and the escape operation is evaluated after the completion of the escape operation (step 506.12).

Next, a training procedure by the above-mentioned ship maneuvering simulator 11 will be described.

When carrying out training, the training conditions are first set. This setting work is performed by selecting a condition to be set from various training menus displayed on the display of the instructor desk 13. In the training menu, many types of training vessels, training areas, environmental conditions, etc. are prepared for each category, and appropriate conditions are selected for each category. When the training conditions are set, a signal relating to the set training conditions is sent to each device such as the visual field simulation device 15 and the sound simulation device 16 through the simulator main computer 14, and a notification sound is emitted from the speaker 20 to perform the training. Notify personnel that "training will soon begin." The trainee will make a final check of various instruments according to the prescribed procedure and will be on standby for a simulated voyage.

When the training is started, the visual field simulator 15 is activated by a command from the main computer 14 and the screen 19 is activated.
The simulated field-of-view image is projected on the screen, and the engine sound and the wind noise created by the sound simulation device 16 are emitted from the speaker 20. The trainee operates the steering device and the main engine control device while embarking on a visual image and various sounds to go on a simulated voyage.

While the training is being performed, the trainee pays attention to the image displayed on the screen 19 and navigates the course designated in advance. When another ship approaches in the image and detects the danger of collision, the course and speed of the own ship are changed to avoid the collision. At this time, the training evaluation device 2
1 determines whether there is a risk of collision with another ship, and if there is no risk of collision, the training ship from the designated course
Calculate the deviation of (own ship) and evaluate the steering ability of trainees. In addition, when there is a risk of collision, the trainee's coping ability will be evaluated based on what kind of escape action was taken. Then, this evaluation result (score) is displayed on the display of the instructor's desk 13.

In this embodiment, the violation of laws and regulations that should be notified to the trainees and instructors and the points to be noticed are also displayed on the display of the instructor desk 13 together with the evaluation result so that the weaknesses of the trainees can be pointed out. It has become.

Next, the evaluation of the coping ability of the trainee by the training evaluation device 21 will be described with a specific example.

FIG. 9 shows an example of the escape operation of the training ship with respect to the crossing ship. When another ship B appears from the starboard side in front of own ship A as shown in FIG. 9 (a), the training evaluation device 21 determines the risk of collision based on the distance R to the other ship, the relative bearing θ, and the like. However, if there is a risk of collision, an evaluation will be performed when evacuating. That is, an appropriate avoidance vessel maneuvering evaluation program is selected according to the flow of FIG.
In the case of (a), the “traffic avoidance vessel maneuvering evaluation program” (step 506) is selected and executed. In this case, if the trainee senses a collision with another ship B and changes the needle to starboard as shown in FIG.
According to the flow of ", the escaping start time is appropriate", "the amount of change operation of the needle is appropriate" and "is the amount of shift operation appropriate"?
After that, when the training ship A and the other ship B pass the closest position as shown in FIG. 9 (c), the training evaluation device 21 determines that the evasion is completed and follows the flow of FIG. "
"Is the passing position appropriate?""Is the number of course changes appropriate?""Is the number of speed changes appropriate?"

Thus, the coping ability of the trainee when a crossing ship appears is scored for each evaluation item in the table below, and the scored result is displayed on the display of the instructor desk 13.

[0028]

[Table 1]

As described above, in the training evaluation apparatus 21 of this embodiment, the evaluation function for each evaluation item is stored in the memory in advance, and based on the positional relationship data with the other ship from the simulator computer 14. Judging the marine vessel maneuvering situation and evaluating the actions taken by the trainees using the evaluation function corresponding to each of the judged marine vessel maneuvering situations, not only the steering ability in the normal time such as "how far from the instruction course", It is possible to objectively determine even the coping ability (judgment ability) at the time of avoidance such as “what kind of coping”.

Moreover, the load on the instructor can be reduced by automatically evaluating the judgment ability of the trainee.
The conventional simulator only evaluates the steering ability of the trainee, and the instructor's judgment ability must be evaluated by looking at the printed track records, etc. Or the instructor's subjectivity will be included in the evaluation result. In the present embodiment, since the evaluation is performed based on the evaluation function set in advance as described above, it is possible to always make an objective and accurate evaluation of the judgment ability of the trainee at the time of avoidance.

[0031]

In summary, according to the present invention, since the marine vessel maneuvering condition is judged from the positional relationship with another ship and the evaluation is made using the evaluation function corresponding to the judged marine maneuvering condition, only the steering ability of the trainee is required. It is possible to make more advanced and objective evaluations, including judgment ability.
