Description

Marine distress location automatic transmitter {APPARATUS FOR AUTOMATIC TRANSMISSION OF MARITIME DISTRESS LOCATION}

The present invention relates to a technology for automatically transmitting a distress position at sea, and more particularly, in connection with a wireless communication device mounted on a ship during a distress at sea, and automatically transmits the distress location to the ship and the ground together with a distress signal to respond quickly and accurately It relates to a device for automatically transmitting a maritime distress location that enables it to be performed.

Marine VHF (Very High Frequency) communication technology can communicate using a specific VHF band so that distress signals or maritime information can be shared among ships moving over the sea using the sea as a transmission path.

In general, ship's distress communication technology transmits DSC (Digital Selective Calling) transmission by manual operation of a person on board, and ships traffic control (Vessel Traffic Control) through distress transmission through automatic ship location transmission device (V-Pass). Service (VTS) can communicate a crisis situation by sending a distress signal to the center. Such a conventional technology has a problem in that it is difficult to respond to situations in which a person on board a ship cannot immediately operate a VHF communication device and an automatic ship location transmitter provided with a button type on board due to an unexpected accident.

In the case of a drowning person such as an outboard crash in a ship sailing along the coast, the method of notifying the main ship and other ships that it is an outboard crash is to transmit an alarm signal using a Digital Selective Calling (DSC) device of the VHF wireless facility and pass the ship ( Two means of distress signal transmission by V-Pass) are in operation. These systems aim to notify a ship or a nearby maritime station of a distress alert using a terminal mounted on the ship. In addition, since the radio equipment installed on the main ship's bridge is directly operated or the moving object is separated from the cradle, the operation method is adopted, so in the event of a sudden outboard crash, the drowned person cannot inform the main ship or other radio stations on their own.

Accordingly, a distress response technology is being developed that informs the ship of the distress situation through a transmitter carried by the drowning person in case of an outboard fall from a ship so that they can respond quickly. Here, the transmitter can be inserted into a life jacket pocket or installed in the form of a necklace and a ring, and there are an automatic mode according to the automatic operation of the water detection sensor in the transmitter and a manual mode in which the victim presses the SOS button.
