Description

[Technical Field]

[0001] The present invention relates to a safe navigation support system for ships that can prevent marine accidents by supporting a ship to quickly recognize other ships that have been called when a danger at sea or a risk of collision with a nearby ship occurs in a situation where the ship cannot clearly recognize the danger, and by preventing marine accidents. [Background technology]

[0002] In order to prevent marine accidents, most ships are generally equipped with the Automatic Identification System (AIS), which has been adopted by the International Maritime Organization (IMO). The AIS is a device that automatically transmits and receives information about a ship's location and identification using radio waves.

[0003] In other words, AIS uses wireless communication technology to track the real-time location and movement route of all ships operating in the world's oceans, helping nearby ships respond quickly in the event of an accident or emergency. It is also used for various purposes, including navigation systems, navigational facility management, and search and rescue operations.

[0004] AIS is now mandatory for foreign-flagged vessels passing through the coastal waters of the Republic of Korea and vessels entering and leaving domestic ports, and as of January 2023, AIS installation has also become mandatory for fishing vessels. Although there are differences not only within Korea but also between countries, there is a trend towards gradually strengthening AIS installation standards worldwide, and even for small vessels and leisure boats where it is difficult to install AIS, at least V-PASS or FLOTTER will be installed as an alternative to AIS functions.

[0005] This AIS transmits various identification information, such as a ship's magnetic position, speed, course, name, call sign, and IMO number, over the very high frequency band (VHF Ch 16), making it easy for land-based control centers and other ships to grasp not only the ship's location but also detailed operational information.

[0006] AIS also has a floating function based on the Global Positioning System (GPS) and a navigation function linked to the Electronic Coastal Roads (EDICS), and can sound a proximity alarm to prevent collisions with other ships in the vicinity, or provide guidance to distant destinations.It can also provide useful information for decision-making by providing additional notification functions such as weather information, fuel level warnings, and obstacle avoidance warnings.

[0007] Furthermore, AIS has four main modes: first, AIS mode displays general ship-related information; second, search mode displays a list of ships visible on the RADAR screen, and by clicking on each, detailed ship information can be viewed; third, voice communication mode; and fourth, MOB (Mobile Offline) mode, which is mainly used for sending emails when an internet connection is unavailable, and can transfer or receive the coordinates of specific points on the electronic nautical chart (EDICS) to a server computer.

[0008] Prior art that applies this AIS technology includes Korean Patent No. 10-1800453, "System and method for preventing ship collisions using AIS information," and Korean Patent No. 10-2596943, "AIS operation data-based collision risk area display device and ship collision prevention system using the same." In the case of Korean Patent No. 10-2543394, "Automatic safe navigation support system for ships," the technology identifies dangers at sea in advance and notifies nearby ships of the risk of collision by sending synthesized voice messages without human intervention, thereby preventing collision accidents.

[0009] This is not to deny the effectiveness of conventional technologies such as the AIS-based collision risk ship or area display for collision prevention mentioned above, or the transmission of synthesized voice messages when there is a risk of collision, but firstly, they are not particularly effective when a ship is aware of the risk of collision with another ship first and wants to avoid it, and secondly, in coastal areas and ports within control regulations, there are many other ships nearby, making it difficult to clearly define the risk of collision between one's ship and other ships.

[0010] Rather, the biggest problem is that when another ship calls your ship via maritime radio, it is difficult for your ship to quickly recognize where the call is coming from, because there are many other ships around your ship.

[0011] In other words, communication and control are carried out by moving to the internationally shared channel 16 (VHF Ch 16) or each VTS nearby channel, but if there are many other ships around your ship, you will need to listen to the voice signals called from other ships via maritime radio, click or touch each other ship individually displayed on EDICS or RADAR, and then check the name and call sign of the called ship.However, when there are many other ships around your ship, the process of checking and specifying the called ship takes a long time.

[0012] Furthermore, if both your ship and the other ship are not from your own country and at least one of them is from another country, you can use Maritime English, which is the international official language. However, if different languages ​​are used, it will be difficult to recognize calls from other ships, and even if you do recognize them, it will be difficult to communicate between them by radio. For example, in the national waters of each country, it is acceptable to communicate in not only Maritime English but also the native language of each country. Summary of the Invention [Problem to be solved by the invention]

[0013] The object of the present invention, which has been devised to solve the above problems, is to provide a ship's safe navigation support system that helps a ship to quickly recognize other ships that have called when a danger at sea or a risk of collision with other ships nearby occurs in a situation where the ship cannot clearly recognize the other ship, and that helps to facilitate radio communication between the ship and other ships even when the ship and other ships speak different languages, thereby preventing marine accidents. [Means for solving the problem]

[0014] In order to achieve the above object, the present invention provides a ship safety navigation support system including various sensors installed on a ship, EDICS and RADAR that display navigation information on each screen in conjunction with GPS and AIS, and a maritime radio that transmits and receives voice signals between the ship and other ships, the system including a voice-to-text converter that converts voice information from a plurality of other ships received by the ship's maritime radio into text information and stores the voice information and text information together for each of the other ships, and a voice-to-text converter that analyzes each of the text information stored in the voice-to-text converter and calculates the name or call number of the ship. A ship's safe navigation support system characterized by including: a ship's own call board end that determines whether there is text information matching the ship's name or call sign; a called other ship designation unit that designates the other ship that has called the ship from the text information for each other ship stored in the voice-to-text conversion unit when text information matching the ship's name or call sign is found via the ship's own call board end; and a called other ship identification display unit that displays an image of the designated other ship on the EDICS or RADAR screen differently so that it can be distinguished from images of multiple other ships when the other ship that has called the ship is designated from the called other ship designation unit.

[0015] The called other ship identification display unit is further characterized in that it displays the name and call sign of the designated other ship that has called the ship in a text image next to an image of the designated other ship.

[0016] The called other ship identification display unit is characterized in that it displays a speaker-shaped icon on top of the image of the designated other ship that has called the ship.

[0017] Furthermore, when the speaker-shaped icon is clicked or touched, the call other ship identification display unit re-outputs the voice information stored in the voice-to-text conversion unit via the ship's own ship's maritime radio.

[0018] The system further includes a character translation storage unit that, if the character information stored in the speech-to-text conversion unit is not the ship's native language or Maritime English, translates it into the ship's native language and Maritime English and stores it as character translation information.

[0019] The called other ship identification display unit displays not only a text image of the name and call sign of the other ship, but also a text image of the character translation information stored in the character translation storage unit, next to the image of the designated other ship that called the ship.

[0020] The system further comprises a voice synthesis storage unit for synthesizing the character translation information stored in the character translation storage unit into voice translation information and storing the voice translation information.

[0021] Furthermore, when the text image of the character translation information is clicked or touched, the call other ship identification display unit outputs the voice translation information stored in the voice synthesis storage unit via the ship's own ship's maritime radio. [Effects of the Invention]

[0022] The ship safety navigation support system of the present invention helps a ship to quickly recognize other ships that have called when a danger at sea or a risk of collision with other ships nearby occurs in a situation where the ship cannot clearly recognize the other ship, and helps to facilitate radio communication between the ship and the other ship even when they speak different languages, thereby preventing marine accidents.

DETAILED DESCRIPTION OF THE INVENTION

[0024] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the ship safety navigation support system according to the present invention will be described in detail below with reference to the accompanying drawings.

[0025] As shown in Figure 1, the ship safe navigation support system according to the present invention includes EDICS 130 and RADAR 140, which display navigation information on their respective screens in conjunction with GPS 120 and AIS 110, as well as various sensors installed on the ship, and a marine radio 150 for transmitting and receiving voice signals between the ship (MS) and multiple other ships (YS). In particular, the system further includes a voice-to-text converter 210, a ship's call board terminal 220, a called other ship designator 230, and a called other ship identification display unit 240. Furthermore, as shown in Figure 8, the system may further include a character translation storage unit 250 and a voice synthesis storage unit 260.

[0026] Various sensors installed on ships for navigation include magnetic compass, gyro compass, echo sounder, speed and distance measuring device, rate of turn indicator, and rudder indicator.

[0027] Additionally, AIS110 is an Automatic Identification System that automatically displays navigation information such as the ship's name, route, speed, and location, while GPS120 is a Global Positioning System that uses satellites to accurately determine your location anywhere in the world.

[0028] In addition, EDICS130 is an Electronic Chart Display & Information System that displays information about the sea route and surrounding area via computer, and RADAR140 is a Radio Detecting and Ranging device that uses the characteristics of radio waves to detect objects and determine their direction and distance.

[0029] The Marine Radio 150 is a marine radio communication device, a radio for use on the sea, not on land, that uses VHF (Very High Frequency) electromagnetic waves in the 100MHz band (especially 156-174MHz). For example, the internationally shared channel used by all ships is channel 16 (VHF Ch 16, 156.8Mhz), and each country or region's Vessel Traffic Service (VTS) calls each ship through the internationally shared channel and then communicates and controls by moving to the channel surrounding each VTS.

[0030] The above-mentioned various sensors, AIS 110, GPS 120, EDICS 130, RADAR 140, and marine radio 150 are essential components for ship navigation, and conventional technologies that add various functions to enable more convenient and safe navigation by utilizing each of these devices are widely known. Against this background, the present invention supports a ship (MS) in quickly recognizing a called other ship (YS) when a danger at sea or a risk of collision with a nearby other ship (YS) occurs in a situation where the ship (MS) cannot recognize the danger.

[0031] For example, when another ship (YS) calls its own ship (MS), it will state its own ship's (MS) name and call sign, then state the name and call sign of the other ship (YS), and then make a request to avoid a collision. At this time, the own ship (MS) must listen to the other ship's (YS) call and confirm where the other ship (YS) is and what its name and call sign are. To do this, the own ship (MS) must look at the EDICS 130 and RADRAR 150 screens and click or touch the image of the other ship (YS) displayed on the screen to check the other ship's (YS) navigation information. In this case, if there are many other ships n (YS1 to YS5) around the own ship (MS) as shown in Figure 1, it is difficult to recognize the other ship 3 (YS3) that has received the call at once, and the image of each of the other ships n (YS1 to YS5) displayed on the screen must be clicked or touched to confirm, which means it takes a long time for the own ship (MS) to recognize the other ship 3 (YS3) that has received the call.

[0032] Therefore, in the present invention, as shown in Figure 1, the device includes a voice-to-text conversion unit 210, a ship's call board end 220, a called other ship designation unit 230, and a called other ship identification display unit 240 so that the ship (MS) can quickly recognize another ship 3 (YS3) that has called when there is a danger at sea or a risk of collision with nearby other ships n (YS1 to YS5) in a situation where the ship (MS) cannot recognize it.

[0033] As shown in Figure 2, the speech-to-text converter 210 converts voice information from multiple other ships (YS1-YS5) received by the ship's (MS) maritime radio 150 into text information and stores the voice information (Speech_n) and text information (Text_n) for each of the other ships (YS1-YS5). That is, the speech-to-text converter 210 is a speech recognition technology and a STT (Speech to Text) technology that receives voice information (Speech) and obtains text information (Text), which is the corresponding syntax. Currently, STT models that use deep learning include WaveNet, and pre-trained speech recognition AI technologies that are distributed free of charge include Google Web, Google Cloud, Bing, Houndify, IBM, Wit, and Sphinx.

[0034] For example, as shown in Figure 2, the speech-to-text converter 210 converts the name (Name_1) and call sign (Call Sign_1) of another ship 1 (YS1) and the names and call signs of other ships called by another ship 1 (YS1) into speech information (Speech_1) and text information (Text_1) and stores them together. This processing is also converted and stored separately for another ship 2 (YS2), another ship 3 (YS3), another ship 4 (YS4), and another ship 5 (YS5).

[0035] As shown in Fig. 3, the own ship call board end 220 analyzes each of the text information (Text_1 to 5) stored in the speech-to-text converter 210 to determine whether there is text information (Text_3) that matches the ship name (Name_Own) or call sign (Call Sign_Own) of the own ship (MS). For example, as shown in Fig. 3, it can be seen that the text information (Text_1, 2, 4, 5) of other ship 1 (YS1), other ship 2 (YS2), other ship 4 (YS4), and other ship 5 (YS5) do not match the ship name (Name_Own) or call sign (Call Sign_Own) of the own ship (MS), but the text information (Text_3) of other ship 3 (YS3) matches that of the own ship (MS).

[0036] At this time, if there is text information (Text_3) that matches the ship name (Name_Own) or call sign (Call Sign_Own) of the own ship (MS) via the own ship call board end 220, as shown in Figure 3, the called other ship designation unit 230 designates the other ship (YS3) that called the own ship (MS) from the text information (Text_n) for each other ship (YSn) stored in the voice-to-text conversion unit 210.

[0037] Next, as shown in Figure 4, when the other ship (YS3) that called the own ship (MS) is specified from the called other ship designation unit 230, the called other ship identification display unit 240 displays an image of the specified other ship (YS3) on the screen of the EDICS 130 or RADAR 140 differently so that it can be distinguished from the images of multiple other ships (YS1, 2, 4, 5). For example, there are various methods to enhance the distinguishability, such as displaying the frequently used image of the other ship (YS) in a triangular shape in a different color or flickering.

[0038] Therefore, as shown in Figures 4 and 5, even if there are many other ships (YS1 to YS5) around the own ship (MS), when other ship 3 (YS3) calls the own ship (MS), the image of the other ship 3 (YS3) that has received the call is displayed on the EDICS 130 or RADAR 140 screen differently from the multiple other ships (YS1, 2, 4, 5), allowing intuitive identification. By clicking or touching the image of the other ship 3 (YS3) identified in this way, the name (Name_3) and call sign (Call Sign_3) of the other ship 3 (YS3) can be immediately seen, allowing the own ship (MS) to quickly respond to and deal with the call from other ship 3 (YS3).

[0039] Furthermore, when another ship 3 (YS3) makes a call to your ship (MS), you can immediately see the name (Name_3) and call sign (Call Sign_3) of the other ship 3 (YS3) without clicking or touching the image of the other ship 3 (YS3) displayed on the screen of EDICS 130 or RADAR 140. In other words, the called other ship identification display unit 240 can display the name (Name_3) and call sign (Call Sign_3) of the other ship (YS3) as a text image next to the image of the specified other ship (YS3) that called your ship (MS), as shown in Figure 5.

[0040] The above-mentioned voice-to-text technology, i.e., voice recognition technology, has become extremely accurate thanks to advances in AI technology, but to confirm whether the voice information (Speech_3) of the other ship 3 (YS3) that made the call actually matches the converted text information (Text_3), the ship (MS) needs to listen to the actual voice information (Speech_3) that was called by the other ship 3 (YS3).

[0041] For this purpose, the called other ship identification display unit 240 can display a speaker-shaped icon on top of the image of the designated other ship (YS3) that called the ship (MS), as shown in Figure 6. This speaker-shaped icon display not only functions to display the image of the other ship 3 (YS3) differently so that it can be distinguished from multiple other ships (YS1, 2, 4, 5), but also performs an input function to listen to the voice information (Speech_3) of the other ship 3 (YS3), which will be described later.

[0042] That is, as shown in Figures 6 and 7, when the speaker-shaped icon is clicked or touched, the voice information (Speech_3) stored in the voice-to-text converter 210 is re-output through the maritime radio 150 of the ship (MS). Therefore, from the standpoint of the ship (MS), the ship (MS) can quickly recognize the other ship 3 (YS3) that has called, and can quickly check the ship name (Name_3) and call sign (Call Sign_3) of the other ship 3 (YS3) in order to respond to or deal with the call of the other ship 3 (YS3). It is also possible to re-verify whether the actual voice information (Speech_3) of the other ship 3 (YS3) matches the converted text information (Text_3), which has the effect of preventing mistakes in calling between the two ships.

[0043] Meanwhile, the present invention helps prevent marine accidents by facilitating radio communication between the own ship (MS) and the other ship (YS) even when they use different languages.

[0044] For example, the speech-to-text technology, i.e., speech recognition technology, of the speech-to-text converter 210 described above is primarily targeted at the native language of the ship (MS) and English, the international official language. However, since ships inevitably encounter ships from other countries during their navigation, it is necessary to support radio communication with other ships (YS) that speak languages ​​other than the native language of the ship (MS) or English. For this purpose, as shown in Figures 8 to 12, a character translation storage unit 250 and a voice synthesis storage unit 260 may be further included.

[0045] That is, as shown in Figures 8 and 9, if the text information (Text_n) stored in the speech-to-text converter 210 is not in the native language of the ship (MS) or Maritime English, the text translation storage unit 250 translates it into the native language of the ship (MS) and Maritime English and stores it as text translation information (Trans Text_n).

[0046] For example, as shown in Figure 9, the speech-to-text converter 210 converts the name (Name_1) and call sign (Call Sign_1) of another ship 1 (YS1) and the names and call signs of other ships called by another ship 1 (YS1) into speech information (Speech_1) and text information (Text_1) and stores them together. At this time, if the text information (Text_1) of another ship 1 (YS1) is not in the native language or in English, the text translation storage unit 250 translates the text information (Text_1) of another ship 1 (YS1) into the native language and English of the ship (MS) and stores it as text translation information (TransText_1). In addition, this processing process is translated and stored separately for another ship 2 (YS2), another ship 3 (YS3), another ship 4 (YS4), and another ship 5 (YS5).

[0047] In this case, the called other ship identification display unit 240 can display not only the text image of the ship name (Name_3) and call sign (Call Sign_3) of the other ship (YS3) next to the image of the designated other ship (YS3) that called the ship (MS), as shown in Figure 10, but also the text image of the character translation information (Trans Text_3) stored in the character translation storage unit 250.

[0048] As shown in Figures 8 and 11, the speech synthesis storage unit 260 synthesizes the text translation information (Trans Text_n) stored in the text translation storage unit 250 and converts it into speech translation information (Trans Speech_n) and stores it. That is, the speech synthesis storage unit 260 is a speech synthesis (Speech Synthesis) technology, a Text to Speech (TTS) technology, which receives text information (Text) and automatically generates corresponding sound waves (Speech). Simply put, the speech of a person selected for the model is recorded, divided into certain speech units, coded, and input into a synthesizer. Only the necessary speech units are reassembled according to instructions to artificially create speech. This traditional waveform splicing method has recently evolved into a statistical parameter model method, making it difficult to distinguish from actual human speech.

[0049] For example, as shown in Figure 11, the text translation storage unit 250 translates the text information (Text_1) of another ship 1 (YS1) into the native language of the ship (MS) and interpreted English and stores it as text translation information (Trans Text_1).Then, the speech synthesis storage unit 260 synthesizes the text translation information (Trans Text_1) into speech translation information (Trans Speech_1) and stores it. This processing is also repeated for other ships 2 (YS2), 3 (YS3), 4 (YS4), and 5 (YS5), and the translation and speech synthesis are stored separately.

[0050] The called ship identification display unit 240 displays a text image of the character translation information (Trans Text_3) stored in the character translation storage unit 250 next to the image of the designated other ship 3 (YS3) that called the own ship (MS), as shown in Fig. 10. In this case, when the text image of the character translation information (Trans Text_3) is clicked or touched, the speech translation information (Trans Speech_3) stored in the speech synthesis storage unit 260 can be output via the marine radio 150 of the own ship (MS), as shown in Fig. 12.

[0051] Therefore, even if the own ship (MS) and the other ship (YS) speak different languages, the own ship (MS) can quickly check the name (Name_3) and call sign (Call Sign_3) of the other ship 3 (YS3) that has called, as well as the text translation information (Trans Text_3) in the native language and maritime English that the own ship (MS) can understand, and if necessary, can even hear the synthesized voice translation information (Trans Speech_3), which helps to facilitate radio communication between the two ships and has the effect of preventing marine accidents from occurring.

[0052] The embodiments of the present invention described above and illustrated in the drawings should not be construed as limiting the technical idea of ​​the present invention. The scope of protection of the present invention is limited only by the matters set forth in the claims, and those skilled in the art may improve or modify the technical idea of ​​the present invention in various forms. Therefore, such improvements and modifications, as long as they are obvious to those skilled in the art, will fall within the scope of protection of the present invention. [Explanation of symbols]
