KR101164305B1 - A salvage location record system - Google Patents

Abstract

The present invention is a positioning and recording system for maritime rescue, which is implemented in a multi-hopping technique rather than a global positioning system (GPS), in which at least two stations communicate navigation information to each other in the form of data packets. Data packets are received at the stations and stored temporarily. The steps of transmitting, receiving and storing are repeated to form a network topology that records the traces of the station mounted on the ship. When a ship is distressed at sea, the most recent data packet sent by the ship provides the location closest to the location of the ship accident. Thus, rescue can be made immediately and the efficiency of rescue operation is improved over traditional methods of estimating the position of the vessel.

Description

Location and record information system for maritime rescue with multi-hopping technology {A SALVAGE LOCATION RECORD SYSTEM}

The present invention relates to a location and record information system for maritime rescue, and more particularly to a location and record information system that does not use a global positioning system (GPS), as well as packet data of stations. A location and record information system for a maritime structure implemented with a multi-hopping technique that utilizes at least two mobile stations for transmission, reception and storage.

About 71% of the earth's surface is water, mostly oceans. Thus, no matter how human culture and technology develop, humanity is highly dependent on the sea in terms of transportation and economy. Many government current maritime policies highlight issues such as maritime traffic safety, maritime rescue, fisheries resource management, and marine environmental protection.

The sailing log of a vessel traditionally provides a detailed sailing record of the sailing of the vessel, including its position and speed, observations from the vessel and events occurring on the vessel. However, because most of the ship's sail log is in the ship rather than in the hands of the rescuers, it is not immediately useful in carrying out the rescue in the event of an accident.

Currently, the International Maritime Distress and Safety System (GMDSS), Ship Security Alert System (SSAS) and Automatic Identification System (AIS) Three systems are included. In the event of a ship disaster, these three systems transmit emergency distress signals through the Global Positioning System (GPS), where they are rescued from where they were sent.

Because global positioning systems (GPS) are too expensive to use to report a ship's position, most ship companies cannot afford to transmit signals frequently through the global positioning system (GPS). Accordingly, the updated position information received at the receiving end is not the same as the actual position of the ship at the time of the accident, and there is often a large mistake in the marine structure such as rescue delay, wrong rescue area, and the like. Research involving the Automatic Ship Recognition System (AIS), conducted by Lloyd's Register Research Unit, suggests that a ship's destination, Insufficient and inaccurate messages about speed, direction, etc. are often indicated. Insufficient messages are sometimes the main cause of inefficient maritime structures.

US Patent 6,778,809 B2, published August 17, 2004, entitled “Mobile Network for Remote Service Areas Using Mobile Stations”, discloses a system and method for transmitting and receiving data in a mobile communication network. The system includes one or more mobile stations for transmitting data in a mobile digital network. Mobile stations are configured to act as buffers / repeaters by storing and forwarding data signals until received by a particular receiving station. Relay means are utilized in this system to form a mobile network. However, the distance from one station to an adjacent station on an international shipping line is generally too far for ships to communicate effectively. Furthermore, the relay means has the following problems.

1. The data source is too far from the destination, resulting in excessive hop count, and communication efficiency drops when the relay count increases.

2. On the shipping line, not all stations are always connected to other ships, so communication is sometimes lost.

According to the above problems, the data signals received once from the affected ship are not enough to confirm the point of accident of the ship. It is urgent to find a way to locate the exact location of the ship's accidents for a timely rescue. Rather than using a Global Positioning System (GPS), the present invention, which utilizes a location and record information system implemented with a multi-hopping technique, may meet this need.
