The present invention relates to a system for recognizing a position at sea for a small vessel for offshore fishing and notifying each vessel at sea, in particular, at least according to the function of transmitting and receiving a separate GPS signal for each vessel. Using short-wave wireless communication to provide services (warning due to invasion of dangerous area, finding location of rescue due to marine safety accident, etc.) using GPS information using shortwave transceiver equipped with system only and basically equipped in small ship A position tracking method and system for offshore ships.

In general, Morse code is used as a means of requesting SOS in the event of an emergency in an ocean where radiotelephones, such as Very High Frequency (VHF) and Single Sided Band (SSB), which are available in offshore waters are not available. The wireless telegraph method used has been used.

However, since the International Maritime Organization (IMO) has made a mandatory introduction of the Global Maritime Distress and Safety System (GMDSS) in February 1999, all vessels sailing at sea. It is no longer possible to use the wireless telegraphy method using Morse code.

GMDSS is simply a state-of-the-art device that periodically transmits the position and status of the vessels in voyage to satellites.In order to supplement and improve the problems of the current distress safety system at IMO, satellite communications and ships are equipped with the latest technology such as digital technology. It is a system of structures established around the world to quickly protect life and property at sea by reinforcing onshore facilities.

Until now, even when an emergency occurred, distress rescue could not be performed quickly because the distress ship could not be located in nearby ships and onshore base stations when radio telegraphy was not available. For example, Hanjin Incheon, which was sailing from San Francisco to Busan in the late 80s, was distressed, but was missing and lost contact.

The introduction of GMDSS enables text communication with onshore base stations and the automatic input of SOS signals to all vessels around the world with a single phone number. In addition, the lifeboat is equipped with a distress transmitter, the rescue ship can quickly determine the position of the distress ship. Currently, most Korean ships are adopting GMDSS system from Samyang Wireless Industrial Co., Ltd. located in Busan, and about 40% of the ships have installed this system.

Since ships subject to GMDSS are limited to passenger ships for international voyages and ships of 300 tons or more, and fishing vessels of 300 tons or more engaged in fishing transport and fisheries manufacturing, vessels that do not meet this standard must be equipped with additional equipment. .

However, distress accidents occurring at sea occur mostly on ships that do not meet GMDSS standards. Especially, these small ships are old ships with no power line, only generators and engines. Due to the depletion of water resources, the ocean is forced to run out of sea, so even a slight wind blows the risk of distress.

Furthermore, after the draft of the ISNT at the third UN Convention on Maritime Law in December 1982, the protection of national water resources in each country through the Exclusive Economic Zone (EEZ), in which the final Convention was officially entered into force in November 1994, As efforts to protect the interests of their own citizens are being increasingly strengthened, operations in waters outside the scope of the fishing agreements have been subject to considerable sanctions (ship capture and arrest / Penalties such as fines) have caused problems for the economic loss of small fishermen.

In addition, in the case of the Republic of Korea as a divided country, it causes significant problems when invading certain areas. In practice, ships that are operating are often operated along fish tanks, so they often deviate from the safe area of operation. There may be no specific indicators, and the current position may be estimated through the chart, but this is not very accurate.

In order to accurately recognize their position on the sea, the GPS system should be applied, but this is a significant economic burden, and ship owners have a limitation such as avoiding it.

In addition, the warning whether determiner 330 may be integrally provided in the system or may be located in the central center (due to the limitation of data processing capability when configured as a single system) connected through a cable communication network.

As described above, the reason for constructing the system is that it is difficult to process the GPS coordinate signals for each of the thousands of ships located near the sea through one communication facility, so the maritime agency 300 divides the water into a plurality of areas. And control the satellite to receive GPS signals of ships located within the percussion, and not to process coordinates and various data based on them, but to recognize only the unique codes of ships located in the area and to control the area. After transmitting to the marine bureau 200 to receive the GPS signal of the ship located in the other area.

Therefore, after receiving the GPS coordinates of the vessels through the shortwave radio communication with the vessels in the marine bureau 200, which has received the unique code of the vessel, the ships are sent to the maritime bureau 300 by the maritime bureau 300 at each branch 200. Is to determine the current state of the entire water based on the data collected in part.

Therefore, briefly look at the overall operation of the vessel and the land system of the position tracking system for offshore vessels using the short-wave wireless communication according to the present invention configured as described above, each vessel is a power source (not shown) from the point of departure from the port or port ) And the control unit 190 controls the GPS module driver 130 to operate the GPS module 120 and detect the presence or absence of an abnormal operation state and GPS coordinates according to the current position. In addition, when there is no abnormality, detection data inside the ship is acquired from the various sensors 180 in the ship.

At this time, the data detected from the various sensors 180 in the vessel is converted into the data for the short-wave radio transmission in the transmission data generation unit 155, and to prevent data corruption during radio transmission through the data modulator 154 After being modulated in a contracted modulation scheme, the speech / data synthesizing unit 152 is provided.

If there is a voice signal, the voice / data synthesizer 152 simply transmits the voice signal to the short wave transmitter 151 when it is not synthesized with the voice signal. The short wave transmitter 151 wirelessly transmits the data to the land system 200. Done.

On the other hand, the GPS module 120 converts the unique code assigned to identify the individual vessels into a GPS signal that can be recognized by the satellite by the GPS signal transceiver 122, which is accessed from the unique code storage 121, It transmits repeatedly and continuously and at the same time receives the GPS signal of its current position.

In this process, the maritime authority system 300 side of the terrestrial land system controls the GPS coordinate receiving area setting unit 320 to warn the GPS of a ship located in a specific area of the offshore divided into a plurality of areas. The GPS module 120 is controlled to receive a signal.

Therefore, the GPS signal receiving unit 311 of the Marine Agency system 300 receives a GPS signal for a ship existing in a corresponding area transmitted from a satellite, and the signal received through the GPS signal receiving unit 311 is a GPS data detecting unit 312. ), GPS data (signals of coordinate values, unique codes, etc. are mixed) is separated.

The GPS data detected by the GPS data detector 312 is separated by a unique code for each ship through the data separator 313 for each code.

The unique code of each ship separated by the data separation unit 313 for each code is arranged through the scan area setting & area line call unit 334 and then transmitted to the local branch having jurisdiction through the internet interface unit 340. It is done.

The vessel management & calling module 290 of the marine bureau 200 that receives the ship-specific code data generated by the scan area setting & area internal caller 334 through the internet interface 270 receives the received ship. Based on the unique code data, the data transmission / reception control unit 250 requests to receive GPS coordinate data values of the corresponding ship through short-wave radio data communication with the corresponding vessel.

The control unit 190 of the vessel 100 receiving the GPS coordinate data sending request requested by the transmission / reception control unit 250 transmits the GPS coordinate data received through the GPS module 120 to the maritime station 200 for shortwave radio data communication.

In addition, the ship data backup & abnormal state detection unit 290 collects the GPS coordinate data and transfers it to the maritime agency 300 through the Internet interface unit 270.

In this case, the scan area ship coordinate database 320 of the Ocean Authority 300 receives and stores GPS coordinate data transmitted from each marine station 200 through the Internet interface unit 340, and stores the GPS coordinate data of the alert status determination unit 330. It is provided to the island chart coordinate matching unit 331.

The sea chart coordinate matching unit 331 receives data on the position of each ship output from the scan area ship coordinate database 320 and displays a boundary line (zero sea, fishing zone, ocean line or passenger line, etc.). The overlapped data is output on the chart.

The data output from the sea chart coordinate matching unit 331 is transmitted to and displayed on the display unit 332 for the administrator to visually recognize, and at the same time it is transmitted to the warning message generation determination unit 333. The warning message is generated. The determination unit 333 classifies the vessel to display the warning message or sound based on the data overlapped by the sea chart coordinate matching unit 331, and outputs an appropriate warning message generation control signal accordingly.

In addition, the receiver 210 of the marine billing system 200 receives a shortwave radio signal transmitted from each ship through a shortwave receiver 211 connected to an antenna, and the signal received by the shortwave receiver 211. Is divided into a voice signal and a text text signal through the voice / data separator 212, and receives and demodulates and outputs a data signal output from the voice / data separator 212 through a data demodulator 214. The data transmission / reception control unit 250 is provided.

The data transmission / reception control unit 250 transmits the inputted text data to the ship data backup & abnormal state detection unit 260, and the ship data backup & abnormal state detection unit 260 is used for each main part of the ship (e.g. For example, the engine, the rudder, etc. of the ship, and stores the data of the state of each part for each ship and based on this to determine the safety of the ship to detect the abnormality accordingly.

During this process, the manager of the marine clearing station system 200 in the jurisdiction and the ship's manager (captain, navigator, etc.) can divide the voice call through short-wave radio communications, which is a common practice, and thus descriptions of other operations are omitted. do.

If the vessel's own defect is found through the vessel data backup & abnormal state detection unit 270 or the necessity of a warning is detected at the warning unit 330 of the marine agency system through the Internet, a warning message is detected.
