Ship status information may include ship operation related information related to the operation of the ship and loading status information of the ship. The vessel information collecting unit 200 may include a voyage data recorder (VDR) for acquiring navigation related information. And may also include a loading computer to collect loading status information of the ship. In addition, the vessel information collecting unit 200 may include various measuring instruments such as a global positioning system (GPS), a speed log, or an anemometer.

GPS (Global Positioning System) is a GPS receiver that can measure the exact time and distance from three or more satellites and accurately calculate the ship's current position according to the triangulation method at each of three different distances. GPS can be used to obtain distance and time information from three satellites and to correct the error with one satellite.

The speed log can measure the speed of the ship. The flowmeter may operate in an ultrasonic, propeller or hot-wire manner and is not limited to the flowmeter used in the present invention.

The anemometer can measure the direction of the ship by measuring the wind direction.

The VDR is a device for recording data related to the navigation of a ship, such as an aircraft's black box. The navigation recorder may record the position, speed, crew, mission worker voice, communicator voice, radar data, water depth, other usage history, engine usage history, wind direction, wind speed and AIS related data. According to the Safety of Life At Sea (SOLAS) regulations, ships built before 1 January 2002 are obliged to install a simplified vessel navigation recorder.

In one embodiment of the present invention, the ship condition information may further include charity information indicating the maneuvering performance of the ship of the ship. Herein, the charity information is the minimum information used for estimating the steering performance of the ship, and the charity information is information about the ship length, width, speed-resistance curve, propeller diameter, thrust reduction factor, rebound ratio, forward non-thrust coefficient curve Shape information, and / or shape information. In addition, the oil strength coefficient can reflect information such as draft, squareness coefficient, displacement, and stern shape coefficient. The charity information may also include linear information about the shape of the vessel.

The control unit 300 can control the overall operation of the ship monitoring apparatus of the present invention. The detailed operation of the control unit 300 will be described in detail with reference to FIG.

The storage unit 400 may store various information collected by the marine information collecting unit 100 and the marine information collecting unit 200. The storage unit 400 may also store data received remotely from the land control.

2 is a block diagram illustrating a controller 300 of a monitoring apparatus according to an exemplary embodiment of the present invention.

2, the control unit 300 of the monitoring apparatus of the present invention includes a motion analysis unit 310, a navigation environment index calculation unit 320, an operation stability determination unit 330, and an exercise measurement statistics learning unit 340 can do.

 2, only the motion analysis unit 310, the navigation environment index calculation unit 320, the operation stability determination unit 330, and the exercise measurement statistics learning unit 340 are shown. However, the control unit 300 may perform various functions It can include modules to perform. The functions performed by the motion analysis unit 310, the navigation environment index calculation unit 320, the operation stability determination unit 330, and the motion measurement statistics learning unit 340 of the control unit 300 may be performed by one control unit 300) can perform both.

The motion analyzer 310 analyzes ship movement information collected from at least one or more motion sensors provided on the ship and predicts a short-term response of the ship based on the analyzed ship movement information. Specifically, the motion analyzer 310 can analyze the current ship motion information to predict short-term ship motion such as six degrees-of-freedom motion of a ship, displacement and velocity of relative corrugation, slamming, decking or propeller exposure . The motion analyzer 310 analyzes the collected information of the marine information collecting unit 100 and the marine information collecting unit 200 in the frequency domain and predicts the short-term response of the ship based on the six degrees of freedom movement of the ship. In various embodiments, the motion analyzer 310 may predict the short-term response of the ship by reflecting the linear information of the ship described above. The control unit 300 can notify the danger, change the route, or control the speed according to the prediction result of the motion analysis unit 310.

The control unit 300 may display the analysis result of the motion analysis unit 310 on the display unit 500.

The navigation environment index calculation unit 320 may calculate the navigation environment index related to the workability of the crew or the sense of boarding. In humans, the motion sickness incidence (MSI) and the motion induced interrupt (MII) can be used to indicate the operating environment index.

The MSI typically expresses the probability of expression of seasickness as a percentage over two hours. The vertical acceleration of human acceleration can be most sensitive to seasickness. The navigation environment index calculator 320 can calculate the MSI when the passenger is exposed to a predetermined vertical acceleration for two hours and the cumulative MSI from the time of the boarding to the calculation.

MII represents the number of occurrences in which a person has to take action to stop and balance a work by a workout for a certain period of time. If the ship is tilted too much due to rolling motion, lateral force is generated by gravity. The larger this value is, the more the work must be stopped in order to balance. The human balance on the ship can be broken by sliding and supporting feet, which can be tipping when the other foot falls off the floor. Sliding can be different according to the material and condition of shoes and floor. Also, when working on a dry floor, a force that is much larger than the force generated by tipping is required to cause sliding, so it is common to consider only tipping.

The navigation environment index calculation unit 320 can calculate MSI and MII based on the measured information using the motion sensor provided on the ship.

On the other hand, the control unit 300 may display the analysis result of the navigation environment index calculation unit 310 on the display unit 500.

The dynamic stability determining unit 330 can determine the dynamic stability of the ship.

During the operation of the waves, the repair area of the ship changes according to the movement of the waves. When the waterline area changes, the stability of the ship also changes. At this time, the stable stability of the ship is called dynamic stability. When a vessel receives disturbance (eg wind or wave) from the outside, a ship may cause periodic motion such as roll or pitch. If the ship can not return to its original state (stillwater state) due to the change of stability due to the change of repair area, This occurs when the ship is dynamically unstable. The dynamic stability may be mixed with the terms dynamic restoration or dynamic restoration in some cases.

The dynamic stability determining unit 330 can determine the dynamic stability of the ship based on the data collected from the maritime information collecting unit 100 and the marine information collecting unit 200 of the ship. The dynamic stability determiner 330 may determine the dynamic stability of the ship to warn of dangers such as parametric roll, surf-riding, broaching, or high wave group of the ship.

The control unit 300 may display the result of the dynamic stability determination unit 330 on the display unit 500. [ Also, in various embodiments, the control unit 300 may determine the navigation guidance according to the dynamic stability determination result.

The motion measurement statistical learning unit 340 calculates the motion statistics of the ship based on the collected information from the maritime information collecting unit 100 and the vessel information collecting unit 200 of the ship in order to plan a ballast to control the draft and the trim of the ship Data can be used.

Specifically, the information about the motion performance of each marine situation can be databaseed through self-learning and the optimal ballasting can be determined through the database. That is, the motion measurement statistic learning unit 340 can learn the correlation between the ship draft, trim, resolution state, motion and acceleration collected from the marine information collecting unit 100 of the ship and the ship information collecting unit 200 have. Also, the motion measurement statistical learning unit 340 can calculate drafts and trims that can operate at the lowest possible horsepower while the risk is low, based on the speed performance of the pre-stored database and trim. For example, in order to improve the motion performance of a ship, it is possible to calculate drafts and trims giving optimum horsepower while ensuring a deep draft.

The control unit 300 may display the draft and trim information calculated by the motion measurement statistics learning unit 340 on the display unit 500. [
