Description

Vessel Navigation Recorder {VOYAGE DATA RECORDER}

The present invention relates to a ship navigation recording device, and more particularly, to allow the various navigation-related data provided from the sensor unit to be stored in the marine recording device and the land recording device in duplicate, thereby causing the ship itself to be caused by an accident. The present invention relates to a ship navigation recorder capable of accurately analyzing navigation information on an accident ship by a land recorder.

Roro Ferry, which killed more than 2,000 people in the Baltic Sea in September 1994, after an overturn in Estonia, a group of experts organized by the International Maritime Organization (IMO) launched a Vorage Data Recorder on all Roro ferries. In addition to recommending the 1995 SOLAS Meeting to force the VDR to be enforced, the Safety of Navigation (NAV) Subcommittee, which is in the process of revising the Chapter 5 of the SOLAS, has decided and Equipment (DE) in cooperation with the DE to review the loading requirements and performance standards, and countries such as Northern Europe are obliged to install a black box recorder for ships of a certain size.

In this way, the ship navigation recorder installed in the ship is for the purpose of maintaining and managing the real-time recording of various data during the operation of the ship, so that the signal conversion device can recognize the navigation data, engine status, navigation data, weather information, etc. After converting into digital signal and transmitting to main system and outputting the transmitted data in the desired form, it automatically records ship navigation data, which saves the trouble of conventional manual log writing and efficient operation management. As a device for constructing a system, the mandatory use of ship navigation recorder has been mentioned for many years.

In addition, there was no objective means for determining the cause when an accident was caused by other conditions such as a ship collision, which caused a lot of troubles between the insurer and the insured. Mandatory equipment, such as airplane black boxes, is used as an objective basis for solving the problems described above (see the IMO NAV SOLAS Convention), and should be stored in the basic concepts of ship black boxes and black boxes by international organizations. As the regulations on the types of data to be made have been established, securing the source technology for the development of ship navigation recorder based on this is an urgent problem.

The present invention is to be stored in the marine recorder and the land recorder to double the various navigation-related data provided from the sensor unit consisting of a weather receiver, GPS receiver, radar, sound detector, speed reader, gyro, bow thruster, etc. A ship navigation recorder is provided.

Best Mode for Carrying Out the Invention A preferred embodiment of the ship navigation recording apparatus according to the present invention will be described with reference to Figs. 1 and 2, and the same names and the same reference numerals will be used for the same components having the same function in the drawings.

Ships are equipped with many types of sensors, such as various navigation-related sensors, automation-related sensors and safety-related sensors. The ship navigation recorder records the data provided by the various sensors and is easily utilized to identify the cause of the accident in the event of an accident. The configuration includes a maritime record connected to the sensor unit 10 equipped with various types of sensors in a wired manner. There is a device 20.

1 is a block diagram showing a ship navigation recording apparatus according to an embodiment of the present invention, the marine recording device 20 for receiving and storing various received signals by wire from the sensor unit 10 for providing navigation data of the ship Is shown.

The sensor unit 10 includes an anemometer 11, a GPS receiver 12, an echo sounder 13, a speed log 14, a gyrocompass 15, a bow thruster. (Bow Thruster 16), Autopilot (17), Engine RPM (18), Radar (19) and the like.

Anemometer 11 receives the weather of the ship's route from the satellite and outputs it to the facsimile, and the GPS receiver 12 receives a signal from the GPS to confirm the position of the ship in operation. In addition, the echo sounder 13 emits sound waves in the water and measures the echoes coming back to observe the depth and the reef, and the speed log 14 measures the speed of the ship in operation. Gyrocompass (15) is a bearing measuring device and transmits a bearing signal, and Bow Thruster (16) transmits information such as the number of revolutions of propeller (propeller), and autopilot (Autopilot) 17) guides the vessel to the proper route to its destination, Engine RPM (18) measures the speed of the engine, and radar 19 identifies objects within a certain range of the vessel currently in service.

All data output or input from the sensor unit 10 is transmitted and received with the control system (not shown) of the ship through a data transmission means such as Ethernet (ETHERNET), where the control system from the sensor unit 10 While all received or detected data is collected through the data transmission means to display respective information, various control information manipulated by the control system is transmitted to the sensor unit 10 through the data transmission means, and as a result, the sensor unit ( 10) and the control system can transmit and receive data by data transmission means.

The data data of the sensor unit 10 is connected to the marine recording device 20 by wire and stored therein.
