Description

Technical Field

[0001] This invention relates to a safe navigation support system for ships, which enables the ship to quickly identify other ships calling for it when the ship is unaware of the danger of collision with other ships or the dangers at sea around the ship, thereby preventing maritime accidents in advance. Background Technology

[0002] Generally, ships are equipped with the Automatic Identification System (AIS) adopted by the International Maritime Organization (IMO) to prevent maritime accidents. AIS is a device that uses radio waves to automatically send and receive information such as the ship's position and identification information.

[0003] In other words, AIS can use wireless communication technology to identify the location and movement paths of all ships navigating in the world's oceans in real time, thereby helping nearby vessels to react quickly in the event of accidents or emergencies involving ships at sea. It is also used for various purposes, such as navigation systems, management of route marking facilities, and search and rescue operations.

[0004] Foreign vessels transiting South Korean waters and vessels entering or leaving South Korean ports are required to be equipped with AIS (Air Traffic Control System). Specifically, AIS installation has been mandatory for fishing vessels since January 2023. While differences exist between countries and within countries, global AIS installation standards are gradually strengthening, and even smaller vessels or recreational boats where AIS installation is more difficult will at least install V-Pass or FLOTTER as alternatives to AIS functionality.

[0005] AIS transmits various identification information about ships, such as position, speed, route, name, call sign, and IMO number, via very high frequency bands (e.g., VHF Ch 16). Therefore, ships, including those in Vessel Traffic Services (VTS), can easily identify each other's positions and detailed navigation information.

[0006] In addition, AIS possesses GPS-based mapping capabilities and navigation functions linked to the Electronic Chart Display Information System (ECDIS). It can also issue proximity warnings to prevent collisions with nearby vessels or provide navigation services for distant destinations. Furthermore, it provides useful data for decision-making by offering supplementary notification functions such as weather information, fuel level warnings, and grounding avoidance warnings.

[0007] In addition, AIS operates in four main modes: the first is AIS mode, which displays general ship-related information; the second is search mode, which displays a list of ships visible on the surrounding radar screens and allows users to view detailed ship information by clicking on each ship; the third is voice communication mode; and the fourth is MOB (Mobile Offline) mode, which is mainly used to send emails when there is no internet connection, and can transmit or receive coordinates of specific points to or from a server computer.

[0008] As a conventional technology for applying the aforementioned AIS technology, there are Korean patents such as "Ship Collision Avoidance System and Method Utilizing AIS Information" (KOP10-1800453), "Collision Hazard Area Display Device Based on AIS Navigation Data and Ship Collision Avoidance System Utilizing the Device" (KOP10-2596943), and "Automatic Safe Navigation Support System for Ships" (KOP10-2543394). Among these, there is a technology that aims to prevent collision accidents in advance by identifying maritime hazards in advance and notifying surrounding ships of collision risks through the transmission of voice-synthesized messages without human intervention.

[0009] This does not negate the effectiveness of existing technologies, such as AIS-based markers of collision risk vessels or areas for collision avoidance, or the issuance of synthesized voice messages in the event of a collision risk. However, firstly, this is not particularly useful if the vessel first identifies the collision risk between other vessels and avoids the collision; secondly, in coastal areas or ports within the VTS area, many other vessels are anchored nearby, making it difficult to clearly define the collision risk between the vessel and other vessels.

[0010] Conversely, the biggest problem is that when other vessels make calls to this vessel via maritime radio communication equipment, it is difficult for this vessel to quickly identify where the call is coming from because there are many other vessels anchored around it.

[0011] That is, all vessels move to international public channel 16 (VHF Ch 16) or the channels around each VTS for communication and traffic control. At this point, if many other vessels are anchored around the vessel, it is necessary to listen for voice signals from other vessels calling via maritime radio communication equipment, tap or touch on other vessels displayed on EDICS or RADAR, and then check the names and call signs of the vessels calling the vessel. However, if many other vessels are anchored around the vessel, there is a problem that it can take a long time to check for other vessels that have not called the vessel and to designate the vessel that ultimately called the vessel.

[0012] Furthermore, if neither this vessel nor the other vessels are domestic, but at least one of them is a foreign vessel, then the internationally used language, namely nautical English, can be used. However, if they use different languages, it can be difficult to recognize calls from other vessels. Moreover, even if recognized, communication can be challenging due to language differences. For example, in the national waters of different countries, communication can be conducted using the respective country's native language as well as nautical English. Summary of the Invention

[0013] Technical issues

[0014] To address the aforementioned problems, the present invention aims to provide a safe navigation support system for ships, which can prevent maritime accidents in advance by enabling the ship to quickly identify other ships calling it, even when the ship is unaware of the danger of collision with other ships or the dangers at sea around the ship. Furthermore, it can facilitate maritime radio communication between the ship and other ships even if the ship uses different languages.

[0015] The purpose of this invention is not limited to the above-described purposes, and those skilled in the art will clearly understand from the following description other purposes not mentioned above.

[0016] Technical solution

[0017] According to the present invention, the above and other objectives can be achieved by providing a safe navigation support system for ships, comprising EDICS and radar that, together with various sensors installed on the ship, are linked with GPS and AIS to display navigation information on each screen, and maritime radio communication equipment for transmitting and receiving voice signals between the ship and other ships, and further comprising: a voice-to-text conversion unit that converts voice information received from other ships into text information via the ship's maritime radio communication equipment and stores the voice and text information of each ship together; a ship call determination unit that analyzes each text information stored in the voice-to-text conversion unit to determine whether there is text information matching the ship's name or call sign; a call ship designation unit that, when receiving text information matching the ship's name or call sign via the ship call determination unit, designates other ships calling the ship from the text information of other ships stored in the voice-to-text conversion unit; and a call ship identification display unit that, when the call ship designation unit designates other ships calling the ship, displays an image of the designated other ship on the EDICS or radar screen in a manner different from that of other ships.

[0018] In addition, the calling vessel identification display unit displays the names and call signs of other vessels as text images next to the images of other vessels calling the vessel on the screen.

[0019] In addition, the calling vessel identification display unit displays a speaker-shaped icon above images of other vessels calling this vessel.

[0020] In addition, when the speaker-shaped icon is clicked or touched, the call vessel identification display unit reproduces the voice information stored in the voice-to-text conversion unit via the ship's marine radio communication equipment.

[0021] Furthermore, the safety navigation support system for ships according to the present invention is characterized by further including a text translation storage unit, which translates the text information stored in the speech-to-text conversion unit into the ship's native language or nautical English and saves it as text translation information when the text information stored in the speech-to-text conversion unit is not the ship's native language or nautical English.

[0022] In addition, the calling vessel identification display unit not only displays text images of the names and call signs of other vessels next to images of other vessels calling this vessel, but also displays text images of text translation information stored in the text translation storage unit.

[0023] Furthermore, the safety navigation support system for ships according to the present invention is characterized by further including a speech synthesis storage unit, which converts the text translation information stored in the text translation storage unit into speech translation information through synthesized speech and saves it.

[0024] In addition, when the text image of the text translation information is clicked or touched, the call ship identification display unit outputs the voice translation information stored in the voice synthesis storage unit through the ship's marine radio communication equipment.

[0025] Beneficial effects

[0026] The safety navigation support system for ships according to the present invention has the following effects: When the ship is unaware of the danger of collision with other ships or maritime hazards around the ship, the present invention can prevent maritime accidents in advance by enabling the ship to quickly identify other ships calling for it, and can also facilitate maritime radio communication between the ship and other ships even when the ship uses different languages.

Detailed Implementation

[0040] The preferred embodiments of the safety navigation support system for ships of the present invention will now be described in detail with reference to the accompanying drawings.

[0041] like Figure 1 As shown, the safety navigation support system for ships according to the present invention includes: an EDICS 130 and a radar 140, both of which, together with various sensors installed on the ship, are linked with a GPS 120 and an AIS 110 to display navigation information on various screens; and a maritime radio communication device 150, which transmits and receives voice signals between the ship's MS and other ships' YS. Specifically, as Figures 1 to 7 As shown, the present invention includes a voice-to-text conversion unit 210, a ship call determination unit 220, a ship call designation unit 230, and a ship call identification and display unit 240, and as... Figures 8 to 12 As shown, the present invention may also include a text translation storage unit 250 and a speech synthesis storage unit 260.

[0042] Various sensors are installed on ships for navigation, such as magnetic compass, gyro compass, echo sounder, speed and distance measuring device, rate of turn indicator, and rudder indicator.

[0043] In addition, AIS110 is an automatic identification system that can automatically display navigation information such as ship name, route, speed and position, while GPS120 is a global positioning system that allows users to accurately determine their location anywhere in the world using artificial satellites.

[0044] In addition, EDICS130 is an electronic chart display and information system that can display chart information and surrounding information via computer, and radar140 is a radio detection and ranging device that can use the characteristics of radio waves to detect objects and determine their direction and distance.

[0045] The marine radio communication equipment 150 is used at sea, not on land, and uses VHF (Very High Frequency) electromagnetic waves in the 100MHz band (specifically 156–174MHz). For example, the international public channel used by all ships is channel 16 (VHF Ch 16, 156.8MHz), and national or regional VTS (Vessel Traffic Services) call ships through the international public channel and communicate and control by moving to channels around each VTS.

[0046] The aforementioned sensors, AIS110, GPS120, EDICS130, radar140, and maritime radio communication equipment150 are essential components for ship navigation. Conventional techniques for utilizing each of these devices to enhance functionality for more convenient and safer navigation are well-known. Against this backdrop, the present invention aims to support the ship's MS in rapidly identifying other vessels_3 (YS_3) that are calling it when a maritime hazard occurs without the ship's MS's awareness or when there is a collision risk with other nearby vessels YS.

[0047] For example, when another vessel YS_n calls this vessel's MS, it will state the MS's name and call sign, then its own name and call sign, followed by a request to avoid collision. At this point, the MS must hear the call and confirm the position of the other vessel YS_n, as well as its name and call sign. To do this, the MS must check the navigation information of the other vessel YS by viewing the screens of EDICS 130 and Radar 140 and clicking or touching the images of the other vessel YS displayed on the screens respectively. In this situation, as... Figure 1 As shown, when there are a large number of other vessels YS_1 to 5 around the ship MS, it is difficult to identify the other vessel _3 (YS_3) that is calling the ship MS at once. Since each image of the other vessels YS_1 to 5 displayed on the screen must be checked by clicking or touching, the ship MS inevitably needs time to identify the other vessel _3 (YS_3) that is calling the ship MS.

[0048] Therefore, as Figure 1 As shown, the present invention includes a voice-to-text conversion unit 210, a ship call judgment unit 220, a calling ship designation unit 230, and a calling ship identification and display unit 240, so that when a maritime danger or a collision with other surrounding ships YS_1 to YS_5 occurs without the ship's MS's awareness, the ship's MS can quickly identify other ships_3 (YS_3) that are calling the ship's MS.

[0049] like Figure 2As shown, the speech-to-text conversion unit 210 converts the speech information Speech_1-5 received from other ships YS_1-5 via the ship's MS's maritime radio communication equipment 150 into text information Text_1-5, and stores the speech information Speech_1-5 and text information Text_1-5 for each ship together. That is, the speech-to-text conversion unit 210 is a speech recognition technology, a STT (speech-to-text) technology, and a technology that receives speech information Speech and obtains the corresponding phrase text information Text. Currently, WaveNet and other deep learning-based STT models exist, and pre-trained and freely distributed speech recognition AI technologies include Google Web, Google Cloud, Bing, Houndify, IBM, Wit, and Sphinx.

[0050] For example, such as Figure 2 As shown, the speech-to-text conversion unit 210 converts the name_1 and call sign_1 of other vessel_1 (YS_1), as well as the name and call sign of the called party, along with the speech information Speech_1, into text information Text_1 and stores them together. Next, this process is performed on other vessels_2 (YS_2) through other vessels_5 (YS_5) respectively, and the conversion and storage are performed separately.

[0051] like Figure 3 As shown, the ship call determination unit 220 analyzes each text message Text_1 to 5 stored in the voice-to-text conversion unit 210 to determine whether there is a text message Text_3 that matches the ship's MS name Name_Own or call sign_Own. For example, as Figure 3 As shown, it can be seen that the text information Text_1, 2, 4, 5 of each of the other vessels YS_1, 2, 4, 5 does not match the name or call sign of this vessel's MS, but the text information Text_3 of the other vessel_3 (YS_3) matches the name or call sign of this vessel's MS.

[0052] At this time, as Figure 3 As shown, when the ship call determination unit 220 receives text information Text_3 that matches the name Name_Own or call sign_Own of the ship's MS, the calling ship designation unit 230 designates other ships_3 (YS_3) that are calling the ship's MS from the text information Text_1 to 5 of each ship stored in the voice-to-text conversion unit 210.

[0053] Next, as Figure 4As shown, when the calling vessel designation unit 230 designates another vessel_3 (YS_3) calling this vessel MS, the calling vessel identification display unit 240 displays an image of the designated other vessel_3 (YS_3) that is different from the other vessels YS_1, 2, 4, 5 on the screen of EDICS 130 or radar 140. For example, there are various methods to increase distinguishability, such as displaying images of commonly used vessels as triangles of different colors, or making them flash.

[0054] Therefore, even in such Figure 4 and Figure 5 In the scenario depicting a large number of other vessels YS_1 to 5 surrounding the ship's MS, when another vessel _3 (YS_3) calls the ship's MS, its image is displayed differently from other vessels YS_1, 2, 4, and 5 on the EDICS130 or radar 140 screen, allowing the ship's MS to visually identify it. By clicking or touching the image of this identified other vessel _3 (YS_3), the ship's MS can immediately learn its name (Name_3) and call sign (Call Sign_3), enabling it to respond quickly and address the calls from other vessels _3 (YS_3).

[0055] Furthermore, when another vessel_3 (YS_3) calls this vessel's MS, the name_3 and call sign_3 of the other vessel_3 (YS_3) can be immediately identified without clicking or touching the image of the other vessel_3 (YS_3) displayed on the EDICS 130 or radar 140 screen. That is, as Figure 5 As shown, the call vessel identification display unit 240 displays the name Name_3 and call sign Call Sign_3 of the other vessel_3 (YS_3) next to the image of the designated other vessel_3 (YS_3) that is calling the MS of this vessel as a text image.

[0056] Although the aforementioned speech-to-text conversion technology (i.e., speech recognition technology) has a high accuracy rate due to the development of AI technology, in order to confirm whether the speech information Speech_3 of other ships_3 (YS_3) calling this ship's MS actually matches the converted text information Text_3, this ship's MS needs to listen to the actual speech information Speech_3 of other ships_3 (YS_3) calling.

[0057] Therefore, such as Figure 6As shown, the calling vessel identification display unit 240 can display a speaker-shaped icon on the image of a designated other vessel_3 (YS_3) calling its own vessel MS. This speaker-shaped icon, by displaying the images of other vessels YS_1, 2, 4, 5 differently from other vessels YS_1, 2, 4, 5, enables the identification of the image of other vessel_3 (YS_3), and also provides an input function for listening to the voice information Speech_3 of other vessel_3 (YS_3).

[0058] That is, such as Figure 6 and Figure 7 As shown, when the speaker-shaped icon is clicked or touched, the voice information Speech_3 stored in the voice-to-text conversion unit 210 can be reproduced through the ship's MS's maritime radio communication equipment 150. Therefore, the ship's MS can quickly identify other vessels_3 (YS_3) calling it, and can also quickly check the other vessels_3 (YS_3)'s name_3 and call sign_3 to respond to their calls. Furthermore, it can re-verify whether the actual voice information Speech_3 of the other vessels_3 (YS_3) matches the converted text information Text_3, thereby preventing erroneous calls between them.

[0059] At the same time, this invention aims to help prevent maritime accidents in advance by facilitating radio communication between the MS on this vessel and YS on other vessels (even when they use different languages).

[0060] For example, the speech-to-text conversion technology (i.e., voice recognition technology) of the aforementioned speech-to-text conversion unit 210 is primarily designed for the ship's MS's native language and English, which is an internationally used language. However, since ships inevitably encounter vessels from other countries during operation, it should also be able to assist in radio communication with other vessels YS that use languages ​​other than the ship's MS's native language or English. Therefore, such as... Figures 8 to 12 As shown, it may also include a text translation storage unit 250 and a speech synthesis storage unit 260.

[0061] That is, such as Figure 8 and Figure 9 As shown, when the text information Text_n stored in the speech-to-text conversion unit 210 is not the native language or nautical English of the ship's MS, the text translation storage unit 250 translates the text information Text_n into the native language and nautical English of the ship's MS and saves it as the text translation information TransText_n.

[0062] For example, such as Figure 9As shown, the speech-to-text conversion unit 210 converts the name_1 and call sign_1 of other vessel_1 (YS_1), as well as the name and call sign of the called party, along with the speech information Speech_1, into text information Text_1 and stores them together. At this time, if the text information Text_1 of other vessel_1 (YS_1) is not the native language or nautical English of the current vessel's MS, the text translation and storage unit 250 translates the text information Text_1 of other vessel_1 (YS_1) into the native language and nautical English of the current vessel's MS and stores it as text translation information TransText_1. Next, this process is performed on other vessels_2 (YS_2) through other vessels_5 (YS_5), and translation and storage are performed separately for each.

[0063] In this case, such as Figure 10 As shown, the calling vessel identification display unit 240 can not only display the text image of the name_3 and call sign_3 of other vessels_3 (YS_3) next to the image of other vessels_3 (YS_3) calling this vessel MS, but also display the text image of the text translation information Trans Text_3 stored in the text translation storage unit 250.

[0064] In addition, such as Figure 8 and Figure 11 As shown, the speech synthesis storage unit 260 converts the text translation information Trans Text_n stored in the text translation storage unit 250 into speech translation information Trans Speech_n through synthesized speech and saves it. That is, the speech synthesis storage unit 260 is a TTS (Text-to-Speech) technology used in speech synthesis, where the machine automatically generates corresponding speech information (Speech) from input text information. Simply put, this technology involves recording the voice of a selected person as a model, segmenting it into certain speech units, adding codes, and then inputting it into a synthesizer. Based on instructions, the synthesizer only recombines the necessary speech units to artificially generate a speaking voice. This previous UTS (Unit-selection Text-to-Speech) method has recently evolved into the SPM (Statistical Parameter Model) method, reaching a level that is difficult to distinguish from actual human speech.

[0065] For example, such as Figure 11As shown, the text translation storage unit 250 translates the text information Text_1 of other ships_1 (YS_1) into the native language and nautical English of the current ship MS and stores it as text translation information TransText_1. At this time, the speech synthesis storage unit 260 synthesizes the text translation information TransText_1 into speech and stores it as speech translation information TransSpeech_1. Next, this process is performed on other ships_2 (YS_2) to other ships_5 (YS_5) respectively, synthesizing speech and storing it.

[0066] like Figure 10 As shown, the aforementioned calling vessel identification display unit 240 displays the text image of the text translation information Trans Text_3 stored in the text translation storage unit 250 next to the image of the designated other vessel_3 (YS_3) calling this vessel MS. At this time, as... Figure 12 As shown, the calling ship identification display unit 240 can output the speech translation information Trans Speech_3 stored in the speech synthesis storage unit 260 when the text image of the text translation information Trans Text_3 is clicked or touched via the ship's MS's marine radio communication equipment 150.

[0067] Therefore, even if the MS on this vessel speaks a different language than other vessels_3 (YS_3), the MS on this vessel can quickly identify the name_3 and call sign_3 of the other vessel_3 (YS_3) that is calling the MS on this vessel, as well as the text translation information Trans Text_3 produced in the MS's native language and nautical English that the MS on this vessel can recognize. If necessary, it can even listen to the synthesized speech translation information Trans Speech_3, which facilitates radio communication between vessels and can help prevent maritime accidents in advance.

[0068] While preferred embodiments of the invention have been disclosed for illustrative purposes, those skilled in the art will understand that various modifications, additions, and substitutions may be made without departing from the scope and spirit of the invention as disclosed in the appended claims.
