Description

Voyage Data Recorder System for Marine

The present invention relates to a voyage data storage system for ships, in particular, to determine the cause of the accident and prevent recurrence by receiving and storing a lot of data generated during the ship operation, such as speed, course, location, and the operating state of the engine related to the operation of the ship The present invention relates to a ship navigation data storage system provided with a plurality of auxiliary VDRs capable of automatically escaping during the sinking of the ship so as to secure data for the ship.

As is well known, the VDR conventionally stores and records most of the situation data that may occur during the operation of the ship, such as the ship's position, time, speed, and course of navigation, and the operating state of the engine. This equipment is essential for identification and prevention of recurrence.

On the other hand, since the conventional VDR is fixedly mounted on the ship, when the ship is sunk due to various accidents such as high collision caused by collision of the ship, tsunami, etc., the data of the VDR cannot be utilized at all until the ship is found. It is.

Therefore, a technology that can confirm only the sinking position has been proposed, an example of which will be examined by the Republic of Korea Utility Model Registration No. 299797 (designation: sinking ship positioning device; referred to as 'quotation of invention 1') This may be illustrated in FIG. 1.

This relates to a sinking ship positioning device, it is characterized by the ability to easily grasp the position of the vessel sunk on the seabed using the balloon and to lift the vessel. This citation is based on the release of a decompression device, which is stored in a casing on the deck when the ship sinks to the seabed and automatically ejects the gas of a high-pressure gas cylinder fixed to the end of the wire connected to the roller and fixed with the high-pressure gas cylinder. The balloon is connected to the end is characterized in that it is inflated above the sea level while inflating.

However, the above-mentioned Cited Invention 1 is required to operate the seal release device in the event of an accident so that the inflated balloon is injured above the sea level. There is a problem that causes an inoperable state due to an operation failure,

The buoyancy of the balloon is difficult to float a rope of sufficient length heavy enough to get wet with water, and when the ship is sunk in the deep sea, because the rope is short, there is a problem that the balloon does not rise above the water surface is not widely used.

The technology has been proposed as Korean Patent Publication 2005-0013463 (Invention: Final Positioning and Lifting Device for Sinking Ships; hereafter referred to as 'Citation Invention 2'), which allows the sinking ship to be lifted. The wire rope, guide rope, EPIRB transmitter and voyage storage box (Boy) with built-in voyages are stored in the ship's storage box and buoys rise due to buoyancy at the same time. By determining the sinking position, and when the final position of the sinking ship is determined, a grab or clamp constituting the lifting vessel is inserted into the guide rope, and then guided and lowered to connect the guide rope and the wire rope. By lifting the weight to lift the diver was configured to be able to lift immediately without the search operation mobilized, this is shown in FIG. This invention 2 is to check the final position of the sinking ship immediately without any search work when the ship sinks and then fixed to the sinking ship by the grab of the crane, which is guided and descended by the guide rope without mobilizing divers and submersibles. By picking up the wire rope connecting weight and lifting it quickly, it is possible to reduce marine pollution, and to reduce the cost of lifting.

On the other hand, this Cited Invention 2 is a buoy with a navigation data storage device weighing tens of kilograms and a sufficient length of more than depth, and the wire rope, guide rope and EPIRB, which are sufficient weights to lift a sinking ship. The buoy with all the transmitters is so large that it becomes very burdensome to load and operate on a normal ship, and in addition, by lifting the buoy data above the sea level by manually removing the voyage data storage device when there is no emergency in case of emergency. Since it is very difficult, it is not widely spread.

An object of the present invention is to install a plurality of auxiliary VDR in a ship to solve this problem, and to store the same data as the main VDR, so that at least one or more auxiliary VDR among the plurality of auxiliary VDR in case of emergence to propagate The present invention provides a ship navigation data storage system that can transmit various types of information related to an accident regardless of a ship sinking state.

In addition, the present invention is to enable the automatic escape and injury of the auxiliary VDR when the ship sinking accident occurs,

The present invention provides a navigational data storage system for a ship that minimizes the installation space and minimizes the occupied space.

The present invention is connected to a video board, a GPS module, a hydraulic pressure sensor and an external computer that can store the image in the data memory, and a camera for photographing the front, rear, left and right of the ship in real time to achieve this object. GPS data memory for storing input / output interface and GPS module data, engine control data memory for storing engine operation state data such as speed, course, engine of ship provided from input / output interface, and microcontroller for controlling them.

Suggest.

In this way, the present invention can provide a convenience that does not need to operate separately in an emergency situation because the auxiliary VDR is automatically injured and automatically fires the radio wave in case of emergency. Since it is the same as the VDR, it can be usefully used for identifying the cause of an accident, calculating a fault rate, and preparing a preventive measure for an accident.

Moreover, the present invention is useful in that one or more secondary VDRs can be injured to launch radio waves and provide accident-related data regardless of the attitude of the vessel, so that efficient and rapid rescue of accident vessels and crews can be achieved. It works.

The present invention thus made will be described in detail with reference to the accompanying drawings.

As shown in FIG. 3, the present invention converts the image signals of the camera 1 and the camera 1 which captures the front, rear, left and right sides of the ship in real time into digital data, and the image data memory 7. To store the data of the video board (2), GPS module (3), hydraulic pressure sensor (4) and input / output interface (5) for connecting to an external computer, and the above-described GPS module (3). Engine control data memory 8 for storing engine operation state data such as speed, course, engine of ship provided from GPS data memory 6 and input / output interface 5, and microcontroller 9 for controlling them With the main VDR 10,

It is connected to the main VDR (10), and consists of a plurality of auxiliary VDR (30) attached to the front and rear and both sides and the upper and lower surfaces of the ship.

4 and 5, the auxiliary VDR 30 is provided with an escape solenoid 13, a boost circuit 23 and an igniter 17 which are operated to release the latch 11 for escape in case of emergency. GPS data, engine control data, and image data provided from the expansion tube 18 and the hydraulic pressure sensor 4 for detecting a surface injury point, the antenna driving motor 19 for the structure radio wave transmission, and the main VDR 10. GPS data memory 26 for storing data, engine control data memory 27, video data memory 28, and an external main VDR 10 or a computer for reading data to input / output data. It is provided with the input-output interface 25 to make.

As described above, in the present invention, a plurality of auxiliary VDRs 30 installed at respective positions of the ships are connected to the main VDR 10 installed at a safe position that is manageable, prevents penetration of moisture, and is easily supplied with power. ) To share data secured by each microcontroller 9 through each input / output interface 5.

That is, the main VDR (10) in the present invention is provided with a GPS module (3) to continuously secure the GPS data, through which the current position of the ship in the GPS data memory (6), and also the speed of the ship, The course and engine operation state data are supplied from the engine control controller 40 and continuously stored in the engine control data memory 8.

In addition, in the present invention, the image data around the vessel is secured from the cameras 1 installed at the front, rear, left and right of the vessel, and stored in the image data memory 7.

Since the GPS, engine control, and image data exceed the limited capacity of the memory as time passes, the data after the set time elapses is sequentially deleted. For example, these memories are stored in the last 5 to 10 minutes. Allow data to accumulate.

In addition, the data of the main VDR 10 is stored in real time in the GPS data memory 26, the engine control data memory 27, the image data memory 28 of the auxiliary VDR 30 due to the nature of accidents that occur accidentally. Thus, the main VDR 10 and the secondary VDR 30 share all data.

In this state, when the ship sinks due to ship collision, fire or explosion accident inside the ship, or damage to the hull by attack weapons such as missiles, the main VDR 10 is submerged and water pressure sensor (4) is activated. As shown in FIG. 6, the pressure sensor 4 pushes the pressure of the outside air by the diaphragm 41 to overcome the elasticity of the bias spring 42 and to the inside thereof, so that the rod 43 receives the infrared light and the light emitting sensor 44. ), So that the submerged state output is generated by the microcontroller 9 so that the main VDR 10 is connected to each auxiliary VDR 30 connected by a cable 14. You will be notified of an emergency. Accordingly, the microcontroller 16 of each auxiliary VDR 30 immediately completes the reception of the data transmitted from the main VDR 10 up to the present time, and transmits an accident recognition signal to the main VDR 10.

Accordingly, the main VDR 10 receives the incident recognition signal from each of the auxiliary VDRs 30, stores the result in a separate memory, and terminates the operation.

In addition, the auxiliary VDR 30 which transmits the accident recognition signal to the main VDR 10 immediately activates the escape solenoid 13. Accordingly, the escape solenoid 13, which has been fixed so that the outside of the auxiliary VDR 30 is fixed, moves out of the latch 11, and pushes the bottom of the VDR 30 fixed between the auxiliary VDR 30 and the installation surface. As the spring 12 is elastically elastic and pushes the auxiliary VDR 30 to the outside as shown in FIG. 7, the auxiliary VDR 30 escapes to the outside, and at this time, the cable connected to the main VDR 10 ( 14) The connectors (15, 15 ') are pulled apart.

Subsequently, the microcontroller 16 of the auxiliary VDR 30 thus escaped immediately activates the booster circuit 23. Accordingly, the igniter 17 is operated to ignite the gunpowder filled in the tube 18. As the gunpowder is burned, the tube 18 expands due to the combustion gas.

As a result, the expanded tube 18 generates buoyancy such that one surface of the auxiliary VDR 30 is above the water surface, and thus the auxiliary VDR 30 rises above the water surface. In this manner, as the auxiliary VDR 30 rises above the water surface, the water pressure sensor 24 of the auxiliary VDR 30 applies the state signal from which the water pressure is removed to the microcontroller 16, and the microcontroller 16 immediately The antenna driving motor 19 is operated to extend the rod antenna 20 so as to be in a state as shown in FIG. 8. At this time, the pressure sensor 24 of the auxiliary VDR 30 can be used the same as the above-described pressure sensor 4, of course.

Subsequently, the microcontroller 16 operates the high frequency transmitter 21, and as a result, the international rescue signal generator 22 connected to the high frequency transmitter 21 operates, thereby outputting the high frequency transmitter 21. High frequency radio waves of the frequency channel designated by.

At this time, the international salvage signal is defined by law.

end. "SOS" 3 times

I. "DE" 1 time

All. Call the distress ship 3 times,

When sending out a voice signal,

end. 3 times of "Distress" or "MAYDAY"

All. Of course, the call sign or call name of the distress ship station should be three times.

Therefore, ships that have passed by, land ship stations, coast stations, coast earth stations, etc. receive them, and quickly access the rescue vessels to retrieve the auxiliary VDR 30, thereby securing necessary data and providing a quick and effective maritime rescue. To make it possible.

In particular, in the present invention, while the ship is sinking, the subsidiary slope, continental shelf, sea ridge, large size zone, flat sea, deep sea plains, sea ridges, seabed protrusions, seabed hills, submarine canyons, etc. ) Is installed, there is a possibility that the auxiliary VDR 30 will not reach the terrain or the obstacle and escape, and in extreme cases may be sunk in the seabed canyon as shown in FIG.

In the present invention, even when the vessel is sunk in any type of seabed terrain, one auxiliary VDR 30 is installed on the front, rear, left, right, and top and bottom surfaces of the ship, so that at least one auxiliary VDR ( 30) will be on the water surface, and when the main VDR (10) is sunk, all the secondary VDR (30) immediately escapes in case of emergency, at least one secondary VDR (30) can be floated above sea level.

Therefore, in the present invention, at least one or more auxiliary VDRs 30 rise above the water surface to transmit the rescue radio wave despite the state of the seabed terrain when the ship is sunk,

The ship station or the land station receives such radio waves, moves the rescue vessel to the corresponding position, recovers the auxiliary VDR 30, and connects a computer to the input / output interface 25 to enable the GPS data memory 26 and the engine control data. By reading the data from the memory 27 and the image data memory 28 and analyzing or transmitting the data to the relevant office for handling accidents, GPS data per hour, speed, course, engine operation status data, and minutes before and after the accident occurred It provides the left and right image data.

Accordingly, it is possible to grasp the occurrence of the accident, the location of responsibility for the occurrence of the accident, the ratio of responsibility, and the like, and the present invention provides not only the status of the occurrence of the accident, but also the calculation of the ratio of the accident occurrence responsibility and data for preventing the occurrence of the accident.
