Description

Docking aid system for ship

The present invention relates to a ship guide system, and more particularly to a ship guide system that can be docked safely to the docking facility.

In general, a ship is a transportation tool used to transport people or cargo by water, and it can be divided into four types of ships, warships, fishing boats, and special ships depending on the purpose of use. These ships are moored in ports for human embarkation and disembarkation and cargo unloading.

The ports are classified into commercial ports, fishing ports, industrial ports, military ports, evacuation ports, and the like, which generally represent most ports. The docks of the port include docking facilities, unloading facilities, warehouses, seaside traffic facilities, passenger facilities. The docking facility is a facility for securely docking a vessel at a port.

However, in the related art, there is a problem in that the ship and the eyepiece frequently collide with the ship when the ship is docked due to inexperienced operation of the ship, bad weather, poor visibility, and the like. In other words, a safety accident may occur when the ship is docked at the berthing facility when the ship is docked due to lack of experience of steering or a momentary mistake, bad weather such as heavy rain and typhoon and strong wind, fog and cloudy weather, or lack of visibility at night. have.

As described above, when a ship collides with the docking facility, the cost and time for repairing the docking facility and the ship are not only very large, but also the docking of other ships is impossible during the repairing of the docking facility, thus making the port reliable, safe and economical. There is also a problem that is lowered. In particular, when oil docks collide with berthing facilities and oil spills into the ocean, marine ecosystems can be severely destroyed, resulting in astronomical loss of costs to restore marine ecosystems.

The present invention provides a ship guidance system that can safely guide the ship to the berthing facility at the time of berthing of the ship to prevent a collision between the ship and the berthing facility in advance.

In addition, the present invention provides a ship guidance system that can safely dock the vessel in the eyepiece facility, and can safely dock the vessel even in bad weather conditions or conditions are not secured to improve port reliability, safety and economics .

In addition, the present invention provides a vessel guidance system that can implement a simple and secure structure of the system to dock the vessel safely and easily.

The present invention, the ship detection unit disposed in the eyepiece facility to detect the eyepiece distance of the vessel entering the eyepiece facility, the wind direction wind speed detection unit disposed in the eyepiece facility to measure the wind direction and wind speed of the eyepiece facility, the vessel A central processing unit for receiving the data sensed by the sensing unit and the wind direction wind speed detecting unit to analyze the state of docking of the vessel, and at least one of the eyepiece facility or the vessel to display various data received from the central processing unit to the outside; A display unit disposed at any one of the display unit and at least one of the eyepiece facility or the vessel, and the central processing unit determines that the vessel has a high risk of an accident. Provide a ship guidance system that includes a warning unit to warn.

Since the vessel is safely guided to the eyepiece facility by the vessel guide system as described above, it is possible to prevent the accident of the eyepiece facility and the vessel in advance, and to prevent damage due to the collision. Damage due to the collision of the berthing facility and the ship includes physical and human losses due to damage of the berthing facility and the ship, loss of port function due to the breakage of the berthing facility, and damage of the berthing facility and the ship. Environmental pollution, etc. Therefore, when the collision between the berthing facility and the vessel is prevented, it is possible to reduce the astronomical cost that is used as the repair and compensation costs of the collision.

In particular, when the ship is docked at the docking facility in bad weather or when the field of view is not secured, it is possible to safely dock the ship to the docking facility with the help of the ship guidance system. Can improve.

In addition, since the ship guide system of the present invention is formed in a simple structure, it is easy to build the system can be easily applied to various types of berthing facilities, it is also possible to greatly reduce the cost required for the construction of the system.

The height detecting unit may include an ultrasonic measuring unit for measuring the height difference between the measuring body and the sea level by sensing the ultrasonic waves to return after firing the ultrasonic waves to the sea level.

The set height may be set to 0.4 m to 0.9 m so that not only the vessel can be detected by the measuring body but also various foreign substances can not be transferred from the sea surface to the measuring body. That is, when the measuring body is placed too close to the sea level, since various organisms may be attached to the measuring body or seawater may penetrate into the measuring body, malfunction and degradation of the measuring body may be triggered. On the other hand, if the measuring body is placed too far from the sea level, since the sensing area of the measuring body is located above the vessel, the vessel sensing function of the measuring body may be lost.

The height adjuster may further include body detecting sensors disposed at upper and lower portions of the measuring supporter to detect the highest and lowest points of the measuring body. The driving unit may move the measuring body in the vertical direction in a range not to deviate from the highest or lowest point of the measuring body. Therefore, since the lifting height of the measuring body is limited by the main body detecting sensors and the driving unit, the operational stability of the ship detecting unit can be improved.

The central processing unit calculates the eyepiece speed from the change in the eyepiece distance of the vessel detection unit, and analyzes the eyepiece state of the vessel by comparing the eyepiece distance of the vessel with a predetermined safety distance according to the wind direction, wind speed and eyepiece speed. can do. The safety distance is an eyepiece distance that can be safely docked by the ship according to the wind direction, wind speed and eyepiece speed, can be stored in the form of a data table in the central processing unit.

The alarm generation unit may include a horn to warn the voice of the risk of an accident when the eyepiece of the vessel. The portable terminal units may include at least one of a mobile phone, a pager, a personal digital assistant (PDA), a radio, or a portable computer.

Therefore, if there is a risk of collision between the vessel and the eyepiece facility when the vessel is docked, the warning unit is operated to transmit a warning to the eyepiece facility and the ship, so that the countermeasure against collision between the eyepiece facility and the ship is prevented. Can be implemented quickly.

On the other hand, the ship detection unit, the wind direction wind speed detection unit, the central processing unit, the display unit, and the warning unit may be provided with a wireless transceiver for transmitting and receiving various data wirelessly. Since the vessel detection unit, the wind direction wind speed detection unit, the central processing unit, the display unit, and the warning unit are not connected by wires, wiring work is unnecessary and post-management can be performed very easily.

Since the ship guide system according to the present invention safely guides the ship to the berthing facility at the time of berthing of the ship, it is possible to prevent a collision between the ship and the berthing facility, and to prevent damage caused by the collision of the ship and the berthing facility. .

When the collision between the ship and the eyepiece facility is prevented by the vessel guide system as described above, it is possible to prevent environmental pollution, astronomical costs for repair and compensation, loss of port function, and the like, which occur when the vessel and the eyepiece facility collide.

In addition, since the present invention can safely and easily dock the vessel to the eyepiece facility, it is possible to securely dock the vessel even in bad weather conditions or conditions are not secured to improve the reliability and safety and economic efficiency of the port.

In addition, the display unit of the ship guidance system is a variety of data necessary for the berthing of the vessel is displayed on the display only when the berthing of the vessel and the advertisement is displayed on the display or the operation is stopped in the usual time, the display unit is blocked by unnecessary operation It can prevent the deterioration of the life of the wealth and the waste of energy.

In addition, the ship guidance system is a variety of data and warning phrases are displayed on the portable terminal of the main people when the ship's berthing, not only can easily check the various data required for the berthing of the ship, but also the risk of collision between the berthing facility and the ship. Warnings can be taken to deal quickly with a crash.

In addition, since the vessel detection unit, the wind direction wind speed detection unit, the central processing unit, the display unit, and the warning unit of the vessel guidance system transmit and receive various data wirelessly using a wireless transceiver, wiring work is unnecessary, and after-care is easy. It can be carried out.

Hereinafter, with reference to the accompanying drawings illustrating a ship guide system according to the present invention.

1 is a view showing a docking facility and a vessel equipped with a ship guidance system according to the present invention, Figure 2 is a block diagram schematically showing the main configuration of the ship guidance system shown in Figure 1, Figure 3 is Figure 1 The front view showing the vessel detection unit shown in.

1 and 2, the ship guide system 1 according to the present invention is provided in the harbor docking facility 4 and the ship 2 to more securely dock the ship 2 to the port. The ship guide system 1 may include a ship detection unit 10, a wind direction wind speed detection unit 20, a central processing unit 30, a display unit 40, and a warning unit 50.

The vessel detection unit 10 may be disposed outside the eyepiece facility 4 to detect in real time the eyepiece distance of the vessel 2 entering the eyepiece facility 4 in real time. The wind direction wind speed detection unit 20 may be disposed outdoors of the eyepiece 4 to measure the wind direction and wind speed of the eyepiece 4 in real time. The central processing unit 30 receives the data sensed by the ship sensing unit 10 and the wind direction wind speed detection unit 20 to be disposed in the interior of the eyepiece facility 4 to analyze the state of docking of the vessel 2. Can be. The display unit 40 may be disposed in at least one of the eyepiece facility 4 or the vessel 2 in order to display the various data received from the central processing unit 30 to the outside. When the warning unit 50 determines that the accident risk of the ship 2 is high by the central processing unit 30, the warning unit 50 warns the danger of the accident to the ship 2 and the eyepiece facility 4. Or at least one of the vessels 2.

1 and 3, the vessel detecting unit 10 includes a measuring instrument body 12 measuring the eyepiece distance of the vessel 2 and a measuring instrument support 14 on which the measuring body 12 is movable. And a height adjuster 16 disposed on the meter body 12 and the meter support 14 to adjust the height between the meter body 12 and the sea level S.

The measuring instrument body 12 is disposed inside the measuring housing 120 and the measuring housing 120 disposed on the measuring support 14, and after the laser is emitted to the vessel 2, the laser reflected from the vessel 2. It may include a laser meter 122 for detecting. The laser meter 122 may be disposed to be rotatable in the horizontal direction or the vertical direction in the interior of the meter housing 120. In addition, the sensing distance of the laser measuring device 122 is formed long enough so that the ship guide system 1 can sufficiently grasp the state of the docking state of the ship 2 and take further action. Usually, the detection distance of the laser measuring device 122 is 300 m or more, but may be appropriately changed according to the situation of the eyepiece facility 4 and the ship 2. Meanwhile, the measuring body 12 may employ various types of distance measuring devices capable of remotely measuring the eyepiece distance of the vessel 2 as well as the laser measuring machine 122.

The measuring instrument support 14 is a frame structure installed at a position close to the sea of the eyepiece facility 4, and the measuring instrument body 12 is disposed to be movable in the vertical direction. Hereinafter, the lifting groove 142 in which the lifting rod 124 is formed long in the vertical direction on the upper part of the measuring housing 120, and the lifting rod 124 is inserted in the measuring supporter 14 so as to be movable in the vertical direction. It will be described as formed. However, the connection structure of the measuring supporter 14 and the measuring instrument main body 12 may employ various connection structures other than the connection structure of the lifting rod 124 and the lifting groove 142.

The height adjuster 16 is disposed in the lower portion of the measuring body 12, the height detecting unit 160 for detecting the height difference (H) between the measuring body 12 and the sea level (S), and the height detecting unit ( It may include a driving unit 162 for moving the measuring body 12 in the vertical direction so that the height difference (H) sensed by the 160 is smaller than the set height.

The height detecting unit 160 may include an ultrasonic measuring unit 160 for detecting the ultrasonic waves coming back from the sea surface (S) after firing the ultrasonic waves on the sea surface (S). The reason why the ultrasonic measuring device 160 rather than the laser measuring device 122 is used for the height detecting unit 160 is that the light such as laser is not reflected on the sea level S, but the ultrasonic wave is reflected at the sea level S Because it is possible.

The driving unit 162 is connected to the case 163 provided on one side of the measuring supporter 14, the driving motor 164 disposed in the case 163, the driving motor 164, and the measuring instrument housing 120. The driving cable 165 may be included. The case 163 may be connected in communication with the hollow interior of the measuring supporter 14. The reel 166 is rotatably provided inside the connection portion of the case 163 and the measuring support 14 as described above. The driving motor 164 may be connected to the reel 166, the rotating shaft to rotate the reel (166). The drive cable 165 is disposed to be movable inside the measuring instrument support 14. One end of the drive cable 165 is connected to the lifting rod 124 of the meter housing 120, the other end of the drive cable 165 is connected in a shape wound on the reel (166). Therefore, when the reel 166 is rotated by the drive motor 164, the other end of the drive cable 165 is wound or unwound by the reel 166, and thus the lifting rod 124 is lifted along the lifting groove 142. Or descend.

On the other hand, the set height of the measuring body 12 and the sea level (S) is not only the vessel (2) is detected on the measuring body 12, but also the height that does not transmit various foreign objects from the sea level (S) to the measuring body (12). Is set. That is, in the case of the small ship 2, if the set height is set too high, the sensing area of the measuring body 12 is located above the vessel 2 and the function of the measuring body 12 may be lost. In addition, if the set height is set too low, the measuring body 12 is located close to the sea level (S) may be the sea water penetrates to the measuring body 12 or attached to marine life. If seawater penetrates into the inside of the measuring body 12, the internal structure of the measuring body 12 may be corroded to the seawater or a short phenomenon may occur in an electronic component. If marine organisms such as barnacles or seaweeds are attached to the exterior of the meter body 12, marine organisms may interfere with the operation of the meter body 12, resulting in loss of the function of the meter body 12 or distortion of the measurement of the eyepiece distance. Can be. The set height is set to 0.4 m to 0.9 m, but may be appropriately changed according to the situation of the eyepiece facility 4 and the ship 2.

The height adjuster 16 can be operated in an automatic mode and a manual mode. If the automatic mode is selected, it automatically operates according to the sea level. If the manual mode is selected, it can be maintained at any height regardless of the height of the sea level.

In addition, the height adjuster 16 is disposed in the lifting groove 142 of the measuring supporter 14, the main body sensor 168 to define the highest point and the lowest point that the lifting rod 124 of the measuring device main body 12 is movable. (169) may be further included. The body detecting sensors 168 and 169 are sensors for detecting a position of the elevating rod 124 and are disposed at upper and lower portions of the elevating groove 142, respectively. The position of the main body sensor 168 (169) is the maximum position that can raise or lower the main body of the measuring device 12, the measuring body 12 is the main body sensor (regardless of the height change of the sea level (S)) 168) 169 may be prevented from being moved to a higher or lower position. That is, when the lifting rod 124 is detected by the upper body detecting sensor 168 among the body detecting sensors 168 and 169, the operation of the driving unit 162 is limited in the direction of raising the lifting rod 124, and the main body is detected. When the lifting rod 124 is not detected by the lower main body sensor 169 among the sensing sensors 168 and 169, the operation of the driving unit 162 is limited in the direction of lowering the lifting rod 124.

In this case, the eyepiece distance indicator 420 may be operated only when the eyepiece 2 is docked, and the operation may be stopped in normal times. Therefore, unnecessary operation of the eyepiece distance indicator 420 can be prevented. The eyepiece distance indicator 420 may be manufactured as an LED having low power consumption and high luminance, and having excellent visibility. Although only the eyepiece distance is displayed on the eyepiece distance indicator 420 as described above, any one of the eyepiece speed, the wind direction, and the wind speed may be displayed differently from the present embodiment.

In addition, the advertisement signboard 422 is operated only when the ship 2 is docked, and the advertisement campaign is normally displayed. Therefore, the efficiency and economics of the advertisement display board 422 can be maximized. The advertisement display board 422 may be made of LCD, LED, or bulb. In the advertisement display board 422, the eyepiece distance, eyepiece speed, wind direction, wind speed, etc. may be simultaneously displayed or various data may be displayed one by one.

The monitoring unit 44 is a device for informing the eyepiece facility 4 and the ship 2 of the eyepiece distance, eyepiece speed, wind direction, wind speed, etc. received from the central processing unit 30. The monitoring unit 44 may include a monitor installed in the guard room (G) and office (O) of the eyepiece facility (4), the steering room of the vessel (2).

Meanwhile, the display unit 40 may further include a plurality of portable terminal units 60 provided by key persons related to the eyepiece facility 4 and the vessel 2. The portable terminal units 60 may include at least one of a mobile phone, a pager, a personal digital assistant (PDA), a radio, or a portable computer. Therefore, since various data are transmitted from the central processing unit 30 to the portable terminal units 60 when the ship 2 is docked, those who need to check the docking state of the ship 2 can check the data more accurately. .

1 and 3, the warning unit 50 is disposed in at least one of the eyepiece facility 4 or the ship 2 to alert the danger of an accident when the ship's eyepiece 2 ( 52). That is, when the risk of collision between the vessel 2 and the eyepiece facility 4 is analyzed by the central processing unit 30, the alarm generator 52 is activated to cause an accident to the eyepiece facility 4 or the ship 2. Danger can be warned.

The alarm generating unit 52 may include a horn 52 for warning of the danger of an accident when the eyepiece 2 is docked. The horn 52 may provide a simple warning sound, such as a beep sound, or provide a warning message that directly informs of a risk of an accident to a human voice. However, the alarm generating unit 52 may also be used as a video device for warning the danger of an accident with a video signal other than audio.

In addition, the warning unit 50 may include a plurality of portable terminal unit 60 provided to the main persons associated with the eyepiece 4 and the vessel (2), respectively. The portable terminal units 60 are the same components as the portable terminal unit 60 of the display unit 40, and instead of displaying a variety of data necessary for the eyepiece when the vessel 2 is docked, the vessel 2 and The difference is that the berthing facility 4 is notified of the risk of collision. Therefore, the description of the configuration of the portable terminal 60 will be omitted.

1 and 3, the ship detecting unit 10, the wind direction wind speed detecting unit 20, the central processing unit 30, the display unit 40, the warning unit 50, and the ship 2 have various data. Wireless transceivers 70, 71, 72, 73, 74, 75, and 76 for transmitting and receiving wirelessly and information may be provided. Accordingly, since the ship guide system 1 wirelessly transmits data between important components, not only the construction of the system is very simple, but also post-management may be very simple. Although there are various types of the radio transceivers 70, 71, 72, 73, 74, 75 and 76, the present embodiment will be described as using an RF module.

Looking at the operation of the ship guide system 1 according to the present invention configured as described above are as follows. Figure 4 is a flow chart showing the operation of the ship guide system according to the present invention.

First, the vessel detection unit 10 is operated to detect the presence of the vessel (2) docked to the docking facility (4), the wind direction wind speed detection unit 20 is activated to detect the wind direction and wind speed of the docking facility (4) do. (S1)

At this time, the ship detection unit 10 detects the height change of the sea level (S) by the ultrasonic measuring device (160). When the height difference H between the measuring body 12 and the sea level S is out of 0.4 m to 0.9 m due to the height change of the sea level S as described above, the measuring body 12 and the sea level S The driving unit 162 of the height adjuster 16 is adjusted to adjust the position of the measuring instrument body 12 so that the height difference H may be located between 0.4 m and 0.9 m.

When the vessel 2 is detected by the vessel detection unit 10 as described above, the vessel detection unit 10 measures the eyepiece distance of the vessel (2). Then, the ship detection unit 10 and the wind direction wind speed detection unit 20 transmits data on the measured eyepiece distance, wind direction, and wind speed to the central processing unit 30. (S2, S3)

The central processing unit 30 calculates the eyepiece speed of the ship 2 using the change amount of the eyepiece distance. The central processing unit 30 analyzes the eyepiece state of the ship 2 by using the eyepiece distance, eyepiece speed, wind direction, and wind speed, and determines whether there is a risk of collision between the ship 2 and the eyepiece facility 4. (S4, S4, S7)

As an example of how the central processing unit 30 analyzes the eyepiece state of the ship 2, there is a method using a data table of the safety distance according to the wind direction, the wind speed, and the eyepiece speed. That is, the safety distance according to the wind direction, the wind speed, and the eyepiece speed is calculated in advance in the central processing unit 30 and stored in a data table form.

Therefore, when the central processing unit 30 calculates the eyepiece speed by using the amount of change in the eyepiece distance transmitted from the ship detection unit 10 when the eyepiece 2 is docked, a safety distance corresponding to the eyepiece speed, wind direction and wind speed is obtained. The eyepiece state of the ship 2 can be analyzed by calculating from the data table and comparing the safety distance and the eyepiece distance. That is, the central processing unit 30 may determine that the smaller the eyepiece distance than the safety distance, the higher the risk of collision between the ship 2 and the eyepiece facility 4. However, the central processing unit 30 may analyze the eyepiece state of the ship 2, there may be a method using a data table of the safety speed according to the wind direction, wind speed and eyepiece distance, various other methods can be applied. have.

On the other hand, when the vessel 2 is detected by the vessel detection unit 10, the display unit 40 displays various data necessary for the eyepiece irrespective of the state of the eyepiece of the vessel (2). That is, the advertisement signboard 422 stops the advertisement and displays the eyepiece speed, eyepiece distance, wind speed, and wind direction received from the central processing unit 30. The monitoring unit 44 displays the eyepiece speed, eyepiece distance, wind speed, and wind direction received from the central processing unit 30 to directly monitor the eye state of the vessel 2 in the office O, the guard room G, and the steering room. To be able. The eyepiece distance indicator 420 displays the eyepiece distance received from the central processing unit 30. In addition, the portable terminal 60 owned by the important persons of the vessel 2 and the eyepiece 4 also display the eyepiece speed, eyepiece distance, wind speed, and wind direction received from the central processing unit 30. (S5 S6)

Accordingly, since various data necessary for the docking of the ship 2 are displayed by the advertisement signboard 422, the monitoring unit 44, the eyepiece distance indicator 420, and the portable terminal units 60, the advertisement facility 422. The ship 2 can be docked more safely.

If it is determined by the central processing unit 30 that the risk of collision between the ship 2 and the eyepiece facility 4 is high, the warning unit 50 is operated to warn of the risk of a collision accident. That is, the horn 52 is operated to warn the vessel 2 and the eyepiece 4 of the danger of a crash, and the portable terminal 60 owned by the important persons of the vessel 2 and the eyepiece 4. Send a warning message indicating the risk of a crash.

 The warning through the portable terminal unit 60 may be repeated only once or repeatedly until the risk of an accident is eliminated at regular time intervals. Therefore, the warning sound of the horn 52 can quickly cope with the risk of collision between the ship 2 and the eyepiece 4, and according to the warning phrase of the portable terminal 60, the ship 2 and the eyepiece ( Wherever the key figures of 4) are located, the risk of collision between the ship (2) and the berth (4) can be ascertained.

When the vessel 2 secures a sufficient safety distance with the help of the warning unit 50 and the display unit 40, the central processing unit 30 is eliminated the risk of collision between the vessel 2 and the eyepiece 4 It is determined that the operation of the horn 52 is stopped, and the transmission of the warning phrase through the portable terminal unit 60 is also stopped. (S9, S10).

When the eyepiece of the vessel 2 is completed, the eyepiece distance indicator 420 is stopped, and the advertisement signboard 422 displays the advertisement campaign. Accordingly, the eyepiece distance indicator 420 may be prevented from unnecessary operation to increase lifespan and reduce driving cost, and the advertisement signboard 422 may be improved in various applications. (S11 and S12)

In this case, the display of various data through the portable terminal unit 60 or the monitoring unit 44 may also be stopped. Of course, it is also possible for the monitoring unit 44 to continuously display various data.

As described above, the ship guidance system according to the present invention has been described with reference to the illustrated drawings, but the present invention is not limited to the above embodiments and drawings, and various modifications are possible by those skilled in the art within the scope of the technical idea of the present invention. Of course.
