Description

Multi-Purpose Blackbox for Vessel}

The present invention relates to a black box for a ship, and more particularly, to a multi-function black box for a ship provided on a ship operating on the sea and providing various functions to effectively perform detection and rescue in the event of a maritime accident.

The black box, which is used as a means of identifying the risk of accidents such as automobiles, ships, and aircraft, is a device installed to identify the causes of accidents occurring in transportation means for transporting passengers and cargo.

Black boxes like this were first introduced to airplanes where it is difficult to find witnesses or circumstances before and after accidents, and recently they are also introduced to means of transportation such as vehicles or ships, becoming clues in traffic and maritime accident disputes.

In the case of an aircraft black box, it consists of two parts: a flight path recorder (DFDR) and a cockpit voice recorder (CVR). have a form

DFDR records various flight information such as altitude, airspeed, heading, and engine thrust during flight for 25 hours.

In addition, a black box for a vehicle, which has recently been widely popularized, is a small image recording device that includes a camera and a memory, and can be installed by simply attaching it to a front windshield in a vehicle.

On the other hand, since accidents occur due to various causes even in the case of ships, the necessity of such a black box has been raised.

In marine accidents, it is often difficult to identify the cause of the accident. Currently, ships are generally equipped with CCTV for internal filming, but this is not equipment installed for the purpose of finding the cause of the accident, and it is difficult to recover the equipment when the ship is sunk. There are downsides.

VDR (vessel voyage recorder) equipment installed on large ships can be used as a kind of marine black box. On the other hand, it does not have information about the video, and it has the disadvantage of considering the possibility of salvage when the ship sinks, so there is a limit to using the VDR as a maritime black box.

In particular, VDR is mandatory only for ships with a capacity of 3,000 tons or more or international ships, and there is no mandatory regulation for small ships and fishing boats, and since the price of equipment reaches tens of thousands of won, owners of small ships and fishing boats It is practically impossible to have the equipment because the cost is very burdensome for them.

Korean Patent Publication No. 10-2015-0030914 proposes a black box device for ships, but this is only a small means of movement that is provided separately from the ship and moves on the sea to determine the location of the ship where the accident occurred. It is impossible to convey the situation of the accident in real time or to identify the actual cause of the accident.

In addition, the black box for ships proposed in the patent is difficult to manage and whether or not it is possible to return to the shore from the sea is uncertain, so the possibility of practical use is low.

Therefore, there is a demand for the development of a professional and inexpensive maritime black box capable of determining the cause of a marine accident even for small vessels exposed to various risks in a maritime environment.
