Description

Ship system that flashes lights using ROT information {VESSEL SYSTEM THAT FLASHES INDICATORS USING ROT INFORMATION}

The present invention relates to a ship system that blinks lights using ROT information, and more particularly, obtains rate-of-turn (ROT) information, blinks lights according to the ship's driving direction, and blinks lights according to the ship's turning speed. It relates to a ship system that adjusts the cycle.

Ship navigation lights are lights that must be installed indispensably, and are determined in accordance with ship lighting regulations (domestic Maritime Safety Act, overseas international rules for preventing collisions at sea). According to the lighting regulations, installation of illegal lights that can mislead ships and threatening operations that interfere with maritime traffic are prohibited. The lighting of a ship is to be installed only with the lights prescribed by law, and navigation lights are divided into mast lights, side lights and stern lights.

Among them, both sidelights are always on, and installed on the left and right sides of the ship, the left sidelight is red and the right sidelight is green. Yanghyeondeung is installed for the purpose of grasping the relationship between the ship and the ship.

Conventional ships have a navigation device that informs the traveling direction of another ship, such as a RADAR, in order to determine the running direction of another ship. However, even if a navigation device such as a VHF is used to communicate with another ship for avoidance operation, a communication error may occur, and it is not possible to immediately determine whether the other vessel immediately takes an avoidance operation. In addition, since the side lights mounted on conventional ships are always on, it is difficult to grasp the running direction of other ships only with the side lights.

According to Laid-Open Patent Publication No. 10-2010-0062519 to solve the problem, a flashing light is installed on a ship navigation light and at the same time, when turning in a specific direction, the flashing light is flashed to easily recognize the turning direction and prevent collisions between ships. An auxiliary signaling device for vessel collision avoidance is proposed.

However, the direction of the rudder is not necessarily the direction of travel of the ship, and unlike a car, the direction of the rudder and the direction of travel of the ship may be different because the ship has a small quick response. 1 is a view showing the direction of the rudder according to the turning of the ship in a conventional ship, showing the direction of the rudder on the lower side of the ship. In the section indicated by the solid line in FIG. 1, when the ship turns to the left and then changes course in the straight direction, the rudder must proceed to the right to catch the rudder effect. In this case, the actual running direction of the ship is port, but the green light turns on because the ride turns to the right.

In this way, the operation of the side lights violates the essential purpose of the side lights, and it is difficult to grasp the encounter relationship between other ships and the own vessel, and it is difficult to grasp the turning intention, so there is a risk that ships may collide with each other.

Therefore, since the direction of the rudder and the driving direction of the ship are different, it may cause confusion to the other ships, so it is the time when technology development research to improve this is required.

Korean Patent Publication No. 10-2010-0062519

The present invention was invented to solve the above problems, and it is possible to immediately determine whether or not the other ship is taking an avoidance action, so that the running direction of the other ship can be easily grasped, and the running direction of the own ship can be easily informed to the other ship, so the ship and the ship Since collision can be prevented, a ship system that uses ROT information to blink lights is a technical solution.

In particular, in the drawings and detailed description, detailed descriptions and illustrations of specific technical configurations and actions of elements not directly related to the technical features of the present invention are omitted, and only the technical configurations related to the present invention are briefly shown or described. did

Prior to explaining the present invention, a conventional vessel has a navigation device that informs the direction of another vessel, such as a RADAR, in order to determine the direction of travel of another vessel. However, even if a navigation device communicates for avoidance operation, a communication error may occur, and it is not possible to immediately determine whether the other vessel immediately takes an avoidance operation. In addition, since the side lights mounted on conventional ships are always on, it is difficult to grasp the running direction of other ships only with the side lights.

In order to solve the problems of the prior art, a ship system that blinks lights using ROT information is proposed.

2 is a configuration diagram illustrating a ship system for blinking indicator lights using ROT information according to an embodiment of the present invention.

A ship system for flashing lights using ROT information according to an embodiment of the present invention includes a collection unit 10, an analysis unit 20, a transmission unit 30, and a light indicator 40.

First, turn rate information (hereinafter referred to as 'ROT') is ship turn rate (turning angular velocity) information, which represents the turning speed of the ship in degrees per minute, and obtains the turn rate in units of 1 second, and the unit is degree/minute.

The collection unit 10 can collect, convert into data, and store the ROT. The ROT can be obtained through an Auto Identification System (AIS) or a turn rate indicator (ROTI), or obtained by calculating the ROT in an operation control unit.

Here, AIS (Auto Identification System) is a system for voyage-related data communication between ships and between ships and between ships and coastal base stations, and has a collision prevention function, a VTS function, and a vessel position reporting system function. All international voyage vessels of 300 tons or more and all domestic voyage vessels of 500 tons or more and all passenger vessels must be equipped with AIS.

Ships can obtain static and dynamic information from AIS. Static information includes MMSI number, IMO number, ship name, line width and length, location of GPS antenna, type of ship, location of fixed antenna in ship, etc. It includes the ship's position, course and speed over the ground, heading, turning angular velocity, and navigation conditions.

Turn rate information (yaw rate) can also be obtained from the rate of turn indicator (ROTI) rather than AIS. The turn rate indicator indicates the turn rate of the ship and is a useful navigation tool when the helmsman changes or corrects the heading. The turn rate indicator can be mounted on ships with a gross tonnage of 50,000 tons or more.

Alternatively, if both AIS and ROTI are not installed, the collection unit 10 further includes a calculation control unit to calculate the heading (HDG) value per unit time of the ship per second from the GPS location information to determine the ROT of the ship. can be obtained

Here, Heading (HDG) means the direction in which the ship is to proceed, and means the angle formed by the stern and aft line and the reference line passing through the ship.

Then, the analysis unit 20 analyzes the ship direction vector based on the data collected from the collection unit 10 to produce a command for the ship traveling direction.

Based on the data on the turn rate, commands can be produced in the direction the ship is traveling, not in the other direction. That is, the analyzer 20 may acquire the ROT direction and produce a command for the ship traveling direction since the gyroscope is built in the ship. A gyroscope is a machine that uses the principle of angular momentum, and can find out the direction by connecting the axis of the wheel to a triple ring and rotating it in any direction.

Alternatively, the analysis unit 20 without AIS or ROTI may obtain the ROT direction from the ROT from which the heading direction value is calculated and derived by the operation control unit, and may produce a heading change command for the port or starboard side of the ship.

In addition, the transmission unit 30 transmits a ship driving direction command to the ship indicator light 40 based on the command generated by the analysis unit, thereby flashing the indicator light 40 for the direction of the ship to indicate the direction of the ship to other ships. You can inform and know the direction of the other line.

3 is an exemplary view showing the operating range and color of the conventional sideboard lamp, and FIG. 4 is a flow chart showing blinking of the sideboard lamp according to an embodiment of the present invention.

With the ship system 1 configured as described above, the indicator light 40 can flicker in the left and right direction.

First, the color and brightness of the indicator light 40 are determined according to lighting regulations (domestic Maritime Safety Act, foreign countries International Regulations for Preventing Collisions at Sea), and the following <Table 1> can be referred to for the ship sidelight recognition regulations.

ship length over 50m 12-50 m less than 12m poet street 3 miles 2 miles 1 mile poet angle 22.5° (112.5°) after each string from the front line

(The viewing angle according to Table 1 is as shown in FIG. 3.)

When the indicator light 40 is an auxiliary light, an LED light is installed adjacent to both side lights, and when the ship driving direction command by ROT is in the port direction, the left auxiliary light flickers, and when it is in the starboard direction, the right auxiliary light is turned on according to the command. may flash.

When the indicator light 40 is a sidelight, the red light may flicker according to the command when the ship driving direction command is in the port direction by the ROT, and the green light may flicker according to the command when the ship is in the right-hand direction.

In addition, as shown in Table 2 below, the blinking cycle of the indicator light 40 can be adjusted according to the angular acceleration of the ship's turning.

ROT number of people cancer Cycle Step 1 Flashing Cycle 0.5 seconds 0.5 seconds 1 second 2-step flashing cycle 1 second 1 second 2 seconds

(Based on Table 2 above, the indicator light 40 uses the principle of light-dark light, in which the lengths of all lights and arms are exactly the same. When the turning speed is increased while being applied to the light, the light/dark cycle can be shortened to alert the operators of other ships, and the 2nd stage flashing cycle appears in the ship's course change in normal times.)

As shown in FIG. 5 , the blinking cycle of the indicator light 40 is adjusted by the analyzer 20 according to the angular acceleration of the vessel, and the blinking cycle adjustment process is as follows.

(a) collecting ROT and calculating the ROT change value per unit time, (b) converting the ROT change value into data, collecting and storing data, (c) if the ROT change value is 5 consecutive with the same code, the data Recognizing the reliability, (d) selecting blinking cycle 1 if the sign of the ROT change value is positive, and selecting blinking cycle 2 if it is negative, (e) blinking the indicator light with the selected blinking cycle, and stopping blinking if ROT=0 It can be done in steps.

ROT means the turning rate (turning angular velocity) of the ship, and the turning angular acceleration per unit time is calculated as the ROT change value.

In addition, in the process (c), if the ROT change value is 5 consecutive with the same code, the basis for recognizing data reliability is as follows.

First, the phenomenon in which the anchor is dragged is called the main anchor, and the change in heading direction during the main anchor is about 20˚ per minute. When a typhoon strikes, the ship anchors down to fix the ship so that it does not move, but the influence of the external force is strong and anchorage occurs. Therefore, a change of 20 degrees per minute in heading heading can be said to be the maximum heading change in the worst case condition. Therefore, when converting rotation per second, the heading changes by about 0.3˚ per second, and the ship rotates by accumulating data for about 5 seconds, taking into account the case of acceleration with the addition of coasting force.

Second, as a result of analyzing the speed by setting a gate line in the coastal waters near Busan Port Route 1, it was confirmed that the average speed was about 15 kts. 15kts means that the ship travels 15 miles per hour, and it can be seen that the ship moves as much as 38.6m in 5 seconds. Therefore, when two ships encounter each other, the distance between the two ships decreases by 77.2 m after 5 seconds, which is similar to the length of the Korean standard ship.

For two reasons, the standard was based on 5 seconds, which is the time required for the ship to proceed as much as the standard ship length. do.

As shown in FIG. 6 by adjusting the flashing cycle of the indicator light 40, an example graph for an embodiment in which the starboard and port changes are continued after the ship's starboard and port changes will be described.

According to the example graph over time, the collected ROT (turning angular velocity) is the right indicator light 40 flickers according to ROT when the ship changes to starboard, and the left according to ROT when the ship changes to port. When the indicator light 40 blinks and the ROT is 0, the indicator light 40 is reset. Here, it is determined that a ship having an ROT of 0 is not turning, and thus the indicator light 40 may stop flickering.

In addition, the ROT change value (turning angular acceleration) calculated by ROT (turning angular velocity) controls the blinking cycle. The indicator light 40 flickers in a flickering cycle. Conversely, when the ROT change value is a negative number, as the turning acceleration (ROT) decreases, the heading angle acceleration of the ship slows down and the indicator light 40 flickers in a two-step flickering cycle.

The ship system for blinking lights using ROT information according to an embodiment of the present invention configured as described above extracts a ship direction vector from the ROT, blinks the light 40 according to the port or starboard direction of the ship, and changes the ROT. It is characterized by adjusting the flashing cycle of the indicator light 40 by calculating the value, and by clearly conveying the traveling direction and changing speed of the ship to other ships, it is possible to prevent collisions between ships by improving the stability and efficiency of ship navigation.

Although the above-described ship system for flickering lights using ROT information according to an embodiment of the present invention has been shown according to the above description and drawings, this is only an example and does not deviate from the technical spirit of the present invention. It will be well understood by those skilled in the art that various changes and modifications are possible within.
