Description

Ship Safety Operation Support System

The present invention relates to a technology applied to a navigation system of a ship, and more particularly, when the operator of a ship navigates along a set route, by displaying status information of the set route to enable the operator to prepare in advance. It's about the system.

Recently, the main interest of the shipbuilding and shipping industry has been focused on economic efficiency, eco-friendliness, and safety of ships, and various technical researches related thereto are actively conducted to commercialize the system accordingly.

In particular, from the viewpoint of ship economics and stability, research is being conducted on the establishment of route plans that can save fuel, technologies for suppressing marine environmental pollution, and various technologies for safe operation.

In addition, e-navigation promoted by the International Maritime Organization (IMO) is accelerating research and development of integrated flight management for decision-making support for safe operation and customized information management service that meets user requirements.

In most cases, it was based on the experience and intuition of the navigator.

Accordingly, technologies for automatic ship route setting are being developed. However, in the automatic ship route setting technology, the navigation plan is established even if the automatic system, satellite communication system, weather observation system, and navigation system provide information with navigation-related equipment installed on the ship. In this case, the complexity of the path calculation increases and the calculation speed slows down because the calculation is performed considering all the various cases.

In addition, when there is a prohibited area in front of the starting point or a prohibited area between the starting point and the destination point, there is a problem of suggesting a route through the prohibited zone because the area where the route can be created is judged from the starting point.

In order to solve the above problems, in Korean Patent No. 10-1346184 'A vessel navigation system and a route control method of the vessel navigation system', when a departure point and a destination point are set for each vessel, all environmental information of the vessel is collected. A technology is provided to provide an optimal route by analyzing and filtering a plurality of reachable points that can be considered during the movement of a ship according to a schedule standard that reflects the environmental information.

However, from a different point of view, there is a technical gap for a device capable of preparing for safe vessel operation by recognizing the vessel operating environment in the path preset by the vessel path automatic setting technologies to the operator in advance, and the need for this is emerging is becoming

And, the terms described below are terms defined in consideration of functions in the present invention, which may vary depending on the intention or custom of the user or operator, so the definition should be made based on the content throughout this specification describing the present invention.

The present invention relates to a ship safe navigation system, wherein the ship safe navigation system is a part of a ship navigation device that collects ship location information, weather information, and chart information and outputs a route between a departure point and a destination point of a ship on a screen. .

In general, the ship safety navigation system outputs a chart as shown in FIG. 1 , and the route is supported on the chart by a method such as automatic or predetermined route display.

The present invention is characterized in that the polar chart 10, the ship graphic simulation 20, and the MSI information 30 are supported and provided in such a ship safe navigation system.

That is, the present invention is a technology for additionally supporting the route provided in such a ship safe navigation system, and when the cursor M is positioned on the route while the ship is operating, the cursor M is displayed as a tooltip screen as shown in FIG. 2 and the like. It is characterized in that it supports the output of the simulation screen of the marine environment and the ship condition expected from the location.

In the present invention, the method of outputting the tooltip screen includes not only a window screen that appears when the mouse cursor M is clicked, but also an output screen that can be expressed by known techniques such as a screen newly output by clicking on a menu screen provided. can

The simulation screen of the present invention includes, as shown in FIG. 2, the ship's sailing speed and direction vector lines on a polar chart 10 in which the distance and direction are displayed based on the ship's position; IMO (INTERNATIONAL MARITIME ORGANIZATION) The four dangerous conditions of operating ships specified in MSC.1/Circ.1228 Parametric Rolling(114), Synchronous Rolling(113), High-wave Attack(112), Surf-riding and broaching(111) ) is displayed and printed.

The polar chart 10 is a chart in which the distance and the bearing are displayed with respect to the position of the ship, and it may be called a general chart in the maritime position display.

Accordingly, the method of displaying the sailing speed and direction of the vessel by the vector line 115 also belongs to the known art.

In MSC.1/Circ.1228 of IMO (INTERNATIONAL MARITIME ORGANIZATION), four dangerous states of operating ships are Parametric Rolling(114), Synchronous Rolling(113), High-wave Attack(112), Surf-riding and broaching(111). In the present invention, various elements such as natural environment information such as in-wave ship information of individual ships, weather information and maritime information, and chart information such as land area, dangerous area, and national border are collected in the present invention for the four dangerous states of the ship. and calculates, collects, collects, and outputs marine environment information using navigation-related equipment, automation systems, satellite communication systems, weather observation systems, and navigation systems installed on ships.

Parametric Rolling (114), defined in MSC.1/Circ.1228, may cause the ship to sway severely left and right when the natural rolling period of the ship and the encounter period of the wave coincide. area that is presumed to be

In addition, Synchronous Rolling (113) is an area where it is estimated that there will be a phenomenon in which the ship is severely shaken left and right even though the natural lateral sway period of the ship and the wave encounter period do not match in the state of receiving waves from the bow or stern side of the ship. .

High-wave Attack (112) is an area where high waves are expected, and Surf-riding and broaching (111) is a case in which the center of the hull is located on the crest of the wave or the uphill wave front of the wave when the ship sails with the wave received from the stern. It is an area where it is presumed that there will be a phenomenon in which the hull is placed parallel to the wave due to the occurrence of abrupt bow sway.

In the present invention, the four dangerous states of the operating vessel calculated in this way are Parametric Rolling (114), Synchronous Rolling (113), High-wave Attack (112), Surf-riding and broaching (111) as shown in FIG. By displaying it on the chart 10, there is a feature that the safety consideration information of the vessel is recognized at a glance based on the position of the vessel.

In addition, the present invention is the polar chart (10) (Polar chart) four dangerous states of the operating vessel Parametric Rolling (114), Synchronous Rolling (113), High-wave Attack (112), Surf-riding and broaching ( 111) are indicated in separate colors.

Accordingly, each dangerous state at the cursor position is displayed in a position and range based on the position of the vessel in the polar chart 10, so that the ship operator can position the four dangerous states for the vessel at the cursor position and It is possible to recognize the vessel, the angle of arrangement, and the distance at a glance.

The present invention has an advantage in that such information is output when the cursor M is positioned on a preset route, so that the state of the vessel can be recognized in all routes.

This feature of the present invention can be of absolute help to the safe operation of a ship, since the captain recognizes the state of the ship in the set route even if the route is set manually or automatically, so that the risk factors on the route can be grasped.

For example, even if the optimal route is set in consideration of risk factors according to the ship route, this is only an optimal environment considering various risk factors, meaning that the lowest level of risk factors remains.

Therefore, the captain should best focus on the route of the ship, and the present invention has the advantage of being able to provide safety environment information for the future route in advance in the navigation of the captain's route.

On the other hand, in the present invention, the ship graphic simulation 20 screen calculates the weather, wave height, waves, static stability index or dynamic stability index 210 of the cursor point on the ship graphic screen as shown in FIG. 3 to obtain numerical information. It is characterized in that it outputs a motion simulation video of the vessel at the cursor point together with.

As shown in FIG. 2, the present invention is a graphic 220 of the waves around the vessel 200 around the graphic screen of the vessel 200. A meteorological graphic (not shown) is output, which provides the ship operator with perceptual information different from the information recognized in the chart by providing a simulation of the risk factor for the ship at the route position of the cursor (M). It has the advantage of being able to respond more easily to safety.

In the present invention, as shown in FIG. 4, the simulation screen collects the vertical acceleration and the encounter frequency of the vessel at the cursor (M) position and evaluates the probability of occurrence of seasickness in percentage MSI (Motion Sickness Incidence) is calculated and graphically outputted, and MSI information 30 that allows passengers to recognize the possibility of seasickness according to the exposure time of the ship environment at the cursor position is output.

Accordingly, since the ship operator can predict not only the behavior of the ship on the future route, but also the effect on the human body by the MSI index, there is an advantage that predictive operation such as warning for the safety of the crew is possible.

The polar chart 10, the ship graphic simulation 20, and the MSI information 30 of the present invention provide a selection menu bar in the basic chart output window so that selective output is possible.

The MSI index will be described using a known paper.

[MSI Index]

The agitation of the vessel that the vessel faces during operation may cause adverse effects such as fatigue, motion sickness, decrease in cognitive ability, and decrease in activity.

In ships, the acceleration of motion plays an important role in causing fatigue, dizziness, changes in body temperature, sweating, yawning, dry lips, headache, abdominal pain, nausea and vomiting due to various causes.

Among them, motion sickness is similar to fatigue, and once symptoms appear, work performance decreases in psychological or physical aspects, and mental activity is sometimes delayed.

And once motion sickness symptoms appear, it is known that it takes a considerable amount of time to recover.

If we look at the MSI index, which is an indicator of the frequency of seasickness in ships, the most important criterion related to vibration in terms of its effect on the human body is frequency.

ISO's human body vibration-related standards divide behaviors affecting the human body into low-frequency motion (0.63 Hz or less) and vibration (1-80 Hz).

In particular, it is analyzed that motion sickness is highly likely to occur in the low frequency range of 0.1 to 0.5 Hz (ISO 2631-1, 1997).

In addition, motion sickness symptoms occur a lot in an environment where people ride for a long time by plane, car, or ship.

It is known that the cause of seasickness is due to the inconsistency between the motion prediction by all human sense organs and the actual motion received, and the work performed by many environmental factors. (ISO 2631-1, 1997).

MSI expresses the probability of seasickness as a percentage with respect to exposure time and exercise acceleration. As the exposure time to exercise acceleration increases, the possibility of motion sickness increases, and adaptation to it increases after a long time. The frequency of motion sickness decreases with age.

On the other hand, in low-frequency exercise of less than 0.5 rad/s, attention and recognition function deteriorate and motion sickness occurs, which causes serious obstacles to work performance such as reduced concentration, difficulty in movement, decreased judgment, and lethargy (ISO 9996, 1996).

The standard of seasickness was created for the evaluation of passenger comfort, and is generally used.

ISO 2631-3 (1985) suggests a method for evaluating the vibration induced in the human body by motion in the range of 0.1 to 0.63 Hz.

However, unlike other human body vibration fields, it is difficult to test and obtain data, so only guidelines for the severe discomfort boundary (Severe Discomfort Boundaries) are presented.

The discomfort region is defined by the relationship between frequency and acceleration, and the range of the limit acceleration causing seasickness is provided as a frequency function and acceleration RMS (Root Mean Square) value for each exposure time. (JFMSE, 28(1), pp. 14~21, 2016. www.ksfme.or.kr Fisheries and Maritime Education Research, Vol. 28, No. 1, Tong: No. 79, 2016. Vertical Acceleration due to Change in Residence Location of Training Vessel Research on reduction

Various studies on motion sickness related to hull motion have been conducted. For the analysis of vertical acceleration according to sea conditions, the acceleration was measured at various locations in the ship.

O'Hanlon et al. (1973) and O'Hanlon and McCauley (1974) reported that when a passenger was exposed to constant frequency and vertical acceleration for 2 hours, MSI, a seasick index that evaluated the probability of seasickness as a percentage (Motion Sickness Incidence) was limited through the error function, and a study on how to evaluate the experiment for 500 cases as a function of exposure time in amplitude or frequency was also proposed.

And a study on the correlation between seasickness and accelerated motion (Lawther and Griffin, 1986) is a representative example. In a recent research case, it was suggested that linear correction to improve vertical acceleration from the initial design stage and linear decision taking into account the location with low vertical acceleration are important to improve the comfortable boarding feeling by evaluating MSI for university training ships (Han, 2013).
