DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings. The same reference numerals are used for the same constituent elements in the drawings and redundant explanations for the same constituent elements are omitted.

The navigation safety diagnosis system according to the present invention includes a device for measuring the marine environment around the ship at present and includes a sensor mounted on the ship or a device for measuring the present marine environment based on information received from the outside . For example, such a device may include a camera installed around the vessel, an accelerometer mounted on the vessel, a gyro, an Automatic Identification System (AIS), a wind direction anemometer, and the like.

It may also include a device for monitoring the current status of the propulsion, main steering and auxiliary steering devices installed on the ship and for measuring or estimating the limits of the steering forces that may occur when using them.

Such a device includes a revolution number measuring device capable of measuring the revolution number of the propeller, and may include engine monitoring equipment capable of measuring the revolution number of the engine.

The angles of the main steering gear and the auxiliary steering gear can be acquired through an angle sensor attached to the ship and the usage limits can be estimated for each. In the case of the limit of the use of the propeller, it is possible to estimate the propulsion force which the ship can generate in addition to the engine characteristic and the propeller thrust characteristic curve based on the current speed of the ship.

In case of the main steering gear and auxiliary steering gear, the current speed and steering angle are substituted into the mathematical model of the steering force, and when the same model is applied, the steering assist force is estimated by estimating the steering force when the steering angle is maximized. have.

In the case of a steering wheel, the torque acting on the steering wheel can be measured through a sensor, and the steering effort margin can be estimated by comparing with the torque limit of the steering actuator.

The navigation safety diagnosis system according to the present invention may include an apparatus for estimating information on the wave in the marine environment around the ship and predicting the direction of change of the wave in the future through the image, the sensor, and the external reception information. The main wave direction and wave height of the wave around the ship can be analyzed to predict the future wave quantity change.

In particular, we used a dominant mathematical model of ocean waves to generate a number of imaginary ocean wavefronts, compare the oceanic wavefronts acquired with each imaginary ocean wavefront, Quot; state ". < / RTI >

Since the use of the 3-D ocean wave spectrum in the generation of imaginary ocean wavefronts and the generation of imaginary ocean wavefronts from the 3-D ocean wave spectra are used to change the main waves and significant wave information, If we derive the nearest imaginary ocean wavefront, we can obtain the main wave direction and significant wave information.

In case of sensor and external reception information, it is used as information on the average wind speed and direction of the surrounding area. This is used as an initial significant wave condition when generating a virtual ocean wave spectrum.

The navigation safety diagnosis system according to the present invention may include an apparatus for estimating an optimal path that the ship can avoid while avoiding danger based on the analyzed wave information. It is possible to present the safest route by calculating the ship's maneuver / movement in a given environment.

Specifically, an apparatus for calculating an escape path of a ship includes an initial state in which the current speed and direction of the ship and the current sea state information generated in the above are initialized, and the speed and the path are variously changed, And finds the path that leads to the smallest departure from the route.

In some cases, a route can be found by setting a new target point that is not the original route. Considering the case of operation of this system, most of the situations requiring rapid computation are considered. For this calculation, the ship motion analysis method (strip method, Ranki panel method, etc.) based on the velocity potential of the fluid is applied can do.

In the case of the initially created flight route, it is a calculation result that does not take into account the steering limit range of the ship. Therefore, it is possible to change the course after confirming that the course can be changed to the corresponding course through the steering operation (steering angle and speed change simulation) The route can be selected to create the final route.

The navigation safety diagnosis system according to the present invention may include an apparatus for presenting an optimum route derived from an optimum route generation unit, a state of a propeller, a steering gear, etc. to an operator. It can present routes on a 2D chart or project routes on a bridge window through augmented reality technology.

Specifically, it is a device for delivering the final navigation route generated from the above to the navigator, and it can be presented as a proper figure on an electronic chart or a direction and a speed projected on a bridge window .

In the navigation safety diagnosis system according to the present invention, when it is determined that any state of the navigation system can not improve the condition of the ship, the navigation system may include a device for recognizing that the ship is in a dangerous situation.

This can convey the current situation to the operator through an alarm or alarm screen. Specifically, it is a device for informing the operator of the case where there is no case in which the moving path can be shifted to the operational limit of the ship in any case in the navigation path calculated above.

If the initial calculation results (motion analysis results) are all above the limits for the ship's movement or some of the results of the motion analysis are below the limits for the ship's movement, Even if the route can be changed in the steering simulation, an alarm may be generated when the steering is out of the steering margin.
