1 is a block diagram of a navigation simulation providing system according to a preferred embodiment of the present invention.

Referring to Figure 1, the present invention navigation simulation providing system, the navigation education content management server 10 for generating and storing the navigation education content, and the user device 40 through a network network, the difficulty in accordance with the user's steering ability The simulation streaming server 20 that provides the navigation simulation contents of the streaming method and the operation state of the user device 40 as an input function evaluates the suitability of mission performance, and then the difficulty corresponding to the user's control ability level It includes an artificial intelligence evaluation server 30 that automatically matches the navigation simulation content of

The navigation education content management server 10 may be one or a combination of two or more of a web server, a mobile server, and a cloud server, and may include a content DB 11 for classifying and storing navigation simulation data.

The simulation streaming server 20 converts the format of the specific navigation simulation content data selected in the navigation education content management server 10 and transmits it to various user devices 40 to be reproduced in real time in the user device 40 .

The user device 40 may use a smart phone, a PC, a notebook computer, a portable or non-portable game machine.

The education content management server 10 provides a web page or provides a mobile platform directly connected to the execution of an application on the user device 40 to log in through the user device 40 and use the service.

The navigation simulation may include a ship according to a user's selection and an automatically set maneuvering difficulty.

In order to determine the user's control ability level, the education content management server 10 performs a test to evaluate the user's control ability.

2 is a flowchart of a test process of the educational content management server 10 .

First, the education content management server 10 requests a test simulation of the simulation streaming server 20 and transmits the test simulation from the simulation streaming server 20 to the user device 40 (S21).

The test simulation may be to evaluate whether the ship arrives at a destination within a predetermined time range without departing from the route set by the ship navigation simulation.

Therefore, it is checked whether a given speed range is maintained during operation (S22), and it is checked whether the route is maintained (S24).

Each time the given speed range is out of range or the route is deviated, the number of times is counted and accumulated (S23, S25), and when the test is finished (S26), the accumulated count is output as an evaluation result.

At this time, the count number is output to the education content management server 10 and the user device 40 , and the education content management server 10 determines the vessel steering ability of the user device 40 who has performed the test.

Then, if there is a request for ship navigation training content from the user device 40 on which the test is completed, the training content management server 10 determines a ship navigation simulation of a level suitable for the level of the user, and the simulation streaming server 20 It can be provided to the user device 40 by requesting it.

In this case, various conditions may be modeled according to the request of the user device 40 in the ship navigation simulation as educational content.

3 is a vessel modeling condition requested by the user device 40 .

First, the user determines the type of vessel to be applied to the simulation through the user device 40 (S31). At this time, as the type of the vessel, a known type of vessel such as a fishing vessel, a cargo vessel, a battleship, or a leisure boat may be selected, and these types are displayed in a list in the education content management server 10 so that the user can select them.

Next, the user determines the size of the vessel from the type of vessel selected through the user device 40 (S31).

The size of the vessel may be provided by the educational content management server 10, a list divided according to the size.

Next, the user selects the steering unit model and the propulsion unit model of the ship whose type and size are determined through the user device 40 ( S33 and S34 ).

The determined ship model information is transmitted to the artificial intelligence evaluation server 30 together with the user's steering ability level information, and the artificial intelligence evaluation server 30 based on the learning result of the past data, the current user's steering ability Considering the level and the difficulty of maneuvering the modeled ship model, the simulation content suitable for the user's level is determined.

That is, the educational simulation content that meets the user level determined regardless of the type of vessel applies the maneuvering difficulty of the vessel modeled through the artificial intelligence evaluation server 30 again, and a new educational simulation according to the result of learning the past data Select content.

Then, the education content management server 10 checks the simulation content suitable for the user level determined by the artificial intelligence evaluation server 30 from the content DB 11 , and provides it to the simulation streaming server 20 .

The simulation streaming server 20 converts the simulation content into a form usable in the user device 40 and provides it to the user device 40 through a network network.

The user device 40 displays the received simulation content and receives the user's manipulation to execute the navigation simulation.

At this time, the simulation content includes a departure model 100 , a navigation model 200 , and an arrival model 300 as shown in FIG. 4 .

The departure model 100 , the operation model 200 , and the arrival model 300 each include predetermined time progression functions R1 , R2 , and R3 .

The time progress functions R1, R2, and R3 are assumed to define a time range from the start of the execution of the departure model 100 , the operation model 200 , and the arrival model 300 to the end of the execution.

The longer the time defined by the time progression functions (R1, R2, R3) is, the more inexperienced the user is in the handling ability.

The departure model 100 , the operation model 200 , and the arrival model 300 have failure transition functions S1 , S2 , and S3 defined, respectively. The failure transition function is generated when the speed and steering angle, which are operating conditions for each section of the modeled vessel, are out of the specified reference range.

As a variable, it is modeled so that an abrupt situation occurs by changing the time and location by placing an abrupt variable that other ships, reefs, and drift ice appear on the route.

In the process of responding to an unexpected situation, it is possible to evaluate whether the time and the steering angle are out of the standard range to evaluate the ability to respond to an unexpected situation.

The failure transition function is calculated as a failure rate function (F1, F2, F3). The failure rate function can be defined as the number of failures with respect to the number of checkpoints in the entire simulation process regardless of the number of failures.

After the information on the number of failures is accumulated in the user device 40 , it may be temporarily provided to the artificial intelligence evaluation server 30 , or may be provided to the artificial intelligence evaluation server 30 in real time when a failure occurs.

The artificial intelligence evaluation server 30 evaluates whether the simulation content is appropriate for the initially set user level.

That is, if the simulation content corresponding to the determined user level is determined in consideration of the maneuvering difficulty of the modeled vessel, but the failure rate of the result of performing the vessel operation simulation is too low or too high, it is evaluated as inappropriate.

By reflecting this evaluation, learning is performed again, and thereafter, simulation content more suitable for the user level can be determined.

As such, the present invention can be performed in various user device environments, and provides navigation simulation content that meets the user's level in consideration of the maneuverability of the selected ship model, and reflects the performance results in learning.

By repeating this process, the present invention can accurately select and provide navigation simulation content slightly exceeding the user's steering ability.

Although the embodiments according to the present invention have been described above, these are merely exemplary, and those of ordinary skill in the art will understand that various modifications and equivalent ranges of embodiments are possible therefrom. Accordingly, the true technical protection scope of the present invention should be defined by the following claims.
