DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a ship information management method and apparatus according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a diagram showing an example of a schematic configuration of an overall system for ship information management according to an embodiment of the present invention; FIG.

Referring to FIG. 1, the shipping operators 120 and 122 are subjects of operating at least one ship 100, 102, and 104, and receive various flight information including route information from each of the ships 100, 102, and 104 in operation. In this embodiment, the main body for collecting information and transmitting / receiving information is a hardware device such as a server or a terminal located in the actual shipping companies 120 and 122 and the ships 100, 102 and 104. In the present embodiment, A shipping company or a ship.

The shipping carriers 120 and 122 and the vessels 100, 102 and 104 transmit and receive information through the maritime satellite communication 110 according to the S-100 standard. Since the maritime satellite communication 110 has difficulty in transmitting and receiving a large amount of data due to a limited bandwidth, it is desirable to transmit and receive simple types of data. A method of receiving data from ships 100, 102, and 104 by shipping carriers 120 and 122 and generating a standardized report document will be described later with reference to FIG.

The vessels 100, 102, and 104 display various information necessary for navigation through an Electronic Chart Display and Information System (ECDIS). For example, ECDIS can superimpose maps and display routes, or display various weather information. In addition, the ECDIS can superimpose the optimum engine RPM detected in the present embodiment on a map and display it together in the route.

The vessels 100, 102 and 104 determine the entire route via at least one port from the departure point to the destination in accordance with the contracted estimated time of departure (ETD) and the estimated arrival time (ETA) do. The vessels (100, 102, 104) can pass through various ports as needed, such as via a port for refueling, or through a port for loading or unloading of cargo. The vessels (100, 102, 104) can determine the route before departure in consideration of various conditions such as the fuel consumption amount, the stay time of the stopover route, the weather, and the like. It is extremely unusual to change the course during the flight, and most of the time, the first set course is followed.

The vessel's route may pass through the Emission Control Area (ECA). It is not possible to use general marine fuels (eg heavy fuel oil) in the emission control area (ECA), and it is not possible to use fuel such as low-pollution fuel such as low-sulfur oil (eg LSS (Low Suplur Surcharge) Should be used. In general, the cost of marine fuels (LSS, etc.) available in the Emission Control Area (ECA) is higher than the cost of marine fuel (HFO, etc.) available in other common areas. In order to reduce fuel costs, it is possible to set up a route that avoids the ECA or minimizes the passage of the ECA, but in this case, if the total distance is greater than before the ECA avoidance, And the total fuel cost may increase. In addition, since the expected departure time and arrival scheduled time of the ship are fixed, if the flight distance becomes long, the speed of the ship must be increased to meet the expected arrival time. In this case, fuel consumption proportional to the cube of speed The total fuel cost can be increased. Therefore, the present embodiment provides a method of minimizing the fuel cost in the route if the route of the ship is determined through various conventional methods.

2 is a diagram illustrating an example of a ship information management apparatus according to an embodiment of the present invention.

2, the ship information management apparatuses 120 and 122 include a communication unit 200, a regulated area determination unit 210, an RPM calculation unit 220, a cost calculation unit 225, an optimization unit 230, 240, a fuel cost database 250, and the like. The ship information management apparatuses 120 and 122 may be implemented by a server located at a shipping company.

The communication unit 200 receives route information from at least one ship and stores the route information in the navigation database 240.

The Regulatory Area Identification Unit (210) uses the ship's route information and the coordinates of the predefined emission control area to determine whether the ship's route passes through the emission control area. The emission control area may be a rectangular area made up of the upper left coordinate value and the lower right coordinate value, or may be an area having various shapes made up of a plurality of coordinates. It can be compared with each coordinate of the route to determine whether the route is within the emission control area. For example, as shown in FIG. 3, there may be a B-C emission control area 300 and an E-F emission control area 310 on the ship's route.

The Regulatory Area Identification Part (210) identifies the operating distance of the emission control area and the remaining general area of the total operating distance of the ship. In the example of Figure 3, flight distance (D _ECA of the discharge regulation area of the total flight distance (D _total) of the route)) is the total distance between the distance and EF between BC, common areas flight distance (D _HFO) is AB , CD, DE, and FG.

The RPM calculation unit 220 calculates the engine RPM of the ship when it passes through the engine RPM (Revolution Per Minute) and the general region of the ship when passing through the emission control area. The total operating time of the ship, which is the difference between the expected departure time and the expected arrival time of the ship, is a fixed value. By dividing the total operating time by the operating time of the emission control area and the operating time of the general area, the speed of the ship in the emission control area and the general area can be known. For example, if the total operating time is T and the operating time a is assigned to the general area, the operating time of the emission control area is (Ta). (D _ECA ) / (Ta) in the emission control area can be calculated by dividing the operation distance D _ECA of the emission control area and the operation distance D _HFO of the general area in the example of FIG. 3, And the ship speed (D _HFO ) / a in the general area. Since the ship speed and engine RPM show the relationship as shown in the following equation, when the ship speed is obtained, the corresponding engine RPM can be obtained.

Since the RPM of each engine in the emission control area and the general area depends on the operation time distributed to the emission control area and the general area, the RPM calculation part 220 calculates the time distribution ratios for the emission control area and the general area, Engine RPMs for the regulated area and for the general area can be obtained for each ratio. An example of a method of distributing time to an emission control area and a general area is shown in FIG.

The cost calculation unit 225 calculates a fuel consumption amount corresponding to each engine RPM of the emission control area and the general region obtained from the RPM calculation unit 220 and a fuel cost of the general area stored in the fuel cost database 250 and a fuel cost of the emission control area To calculate the total fuel cost of the whole route. The fuel cost database 250 can identify and store the cost of various fuels such as HFO and LSS through the Bunker Delivery Note (BDN).

Since the engine RPMs of the emission control area and the general area are different according to the time allocated to the emission control area and the general area, that is, the time distribution ratio, the cost calculation part 225 calculates the fuel cost per time distribution ratio. For example, the fuel consumption of a ship is proportional to the cube of the engine RPM, so that it can be obtained by the following equation.

Where K and A are predefined constants according to the vessel.

The optimization unit 230 determines engine RPMs in the emission control area and the general area where the minimum cost occurs based on the total fuel cost calculated for each time distribution ratio, and transmits the engine RPM to the ship. The optimizer 230 may transmit the optimal engine RPM to the ship via marine satellite communication in accordance with the S-100 standard, and the ship may display the optimal engine RPM in the ECDIS.

Depending on the embodiment, the allowable range of engine RPM available on the vessel may be defined separately. For example, as shown in FIG. 5, there is a maximum engine RPM 500 and a minimum engine RMP 530 that can be used in a ship, and there is a possibility of causing a problem with the hull structure due to the vibration frequency, (510) -low 520) may exist. In this case, the allowable engine RPM range of the ship is between the maximum RMP (500) - High (510), Low (520) - minimum RMP (530). The optimizing unit 230 determines whether the engine RPM in the case where the minimum cost occurs next falls within the allowable range if the engine RPM in the case where the minimum cost occurs does not fall within the allowable range. In this way, the optimizing unit 230 selects the RPMs within the permissible range of the engine RPMs of the emission restriction area and the general area to the optimum RPM, and transmits them to the ship.

FIG. 3 is a simplified diagram illustrating a route according to an embodiment of the present invention. FIG.

Referring to FIG. 3, the ship arrives at point G via B, C, D, E, F starting from point A. The path between the B-C 300 and the E-F 310 is a route belonging to the emission control area and the rest A-B, C-D, D-E and F-G is a route belonging to a general area other than the emission control area.

Therefore, the total operating distance (D _ECA ) of the emission control area is the sum of the distance between BC and EF, and the total operating distance (D _HFO ) of the general area is the distance between AB, distance between CD, Distance, and distance between FG.

4 is a view showing an example of a method of distributing the operating time to the emission control area and the general area according to the embodiment of the present invention.

Referring to FIGS. 3 and 4 together, the total operating time (T _total ) used to operate the total operating distance D _total between AGs is fixed. The total operating time T _total can be divided into unit times u of a predetermined number (for example, N).

First, one unit time (u) may be allocated to the operating time (T _HFO ) of the general area, and (N-1) unit times may be allocated to the operating time (T _ECA ) of the emission control area. The ship information management apparatus calculates the engine RPM of the emission control area and the general area according to the unit time allocation.

Next, two unit times (u) are allocated to the operating time (T _HFO ) of the general area, and (N-2) unit times are allocated to the operating time of the emission control area (T _ECA ) Calculate the engine RPM of the general region.

In this way, the RPM of the engine in the emission regulated area and the general area is calculated by varying the number of times of allocation per unit time in the general area and the emission control area.

For example, the total operating time (T _total ) is divided into 1000 unit times (u), the unit time (u) is distributed to the operating time (T _HFO ) -i) unit time, the RPM of the engine in the emission-regulating region and the general region and the resulting fuel cost can be obtained by the following equation.

Here, H is an identifier indicating a general area, and SLIP indicates a constant value indicating the amount by which the propulsive force is not transmitted as it is due to the external resistance of the ship but is reduced.

Here, E is an identifier indicating a general area.

Therefore, when the unit time (u) is distributed to the operating time (T _HFO ) of the general area and the (1000-i) unit time is allocated to the emission control area, the total fuel cost is as follows.

the engine RPM of the general region and the engine RPM of the emission region when the total fuel cost is minimized while changing i from 1 to 1000 can be obtained by the optimum engine RPM.

5 is a diagram showing an example of an allowable range of engine RPM of a ship according to an embodiment of the present invention.

Referring to FIG. 5, the maximum RPM 500 and the minimum RPM 530 that the engine of the ship can operate and the RMP range High (510 ) -Low 520). Therefore, the allowable range of the engine RPM is between the maximum RPM (500) - High (510), Low (520) - minimum RPM (530).

The optimum RPM should be within this acceptable range. If the engine RPM of the total fuel cost control area and the general area is not within the allowable range, then the engine RPM at the minimum cost is within the allowable range. In this way, the RPM of the engine in the emission control area and the general area satisfying the allowable range in the order of the total fuel cost is grasped.

FIG. 6 is a view illustrating an example of a ship information management method according to an embodiment of the present invention.

Referring to FIG. 6, the ship information management apparatus receives route information from a ship (S600). The ship information management apparatus determines the operation distance of the emission control area among the total operation distance of the ship based on the route information and the coordinates of the predefined emission control area (S610).

The ship information management apparatus changes the time distribution ratio of distributing the total operating time of the ship to the emission control area and the general area (S620), and discharges the ship based on the operating distance of the emission control area and the general area, Engine RPMs of the regulated region and the general region are respectively calculated (S630). The ship information management apparatus can adjust the time allocation ratio by dividing the total operation time into a certain number of unit times and changing the number of unit times allocated to the emission restriction area and the general area as shown in FIG.

Then, the ship information management apparatus calculates the total fuel cost by the time sharing ratio based on the fuel ratios of the engine RPM, the emission control area and the general area of the emission control area and the general area (S640) The engine RPM of the emission control area and the general area where the minimum cost occurs is provided to the ship (S650).

When the allowable range of the engine RPM of the ship exists according to the embodiment, the ship information management device determines that the engine RPM of the emission control area and the general area when the lowest cost among the total fuel ratios by the time distribution ratio occurs is within the allowable range And identify engine RPMs in regulated areas and general areas in order of decreasing total fuel cost until they fall within acceptable limits. The ship information management system provides the engine with the engine RPM of the emission control area and the general area within the allowable range.

7 is a view showing another example of the schematic configuration of the overall system for managing ship information according to the present invention.

7, the ship information management apparatus 720 receives various ship reports from at least one shipping carrier 710 and 712, and transmits various ship reports to systems of various international organizations such as IMO and EU MRV (hereinafter, ) 730 and 732 according to the standard format.

The shipping operators 710 and 712 operate the at least one ship 100, 102 and 104 and when they receive the ship report such as the fuel usage amount from each ship 700, 702 and 704 in operation, the ship report is transmitted to the ship information management device 720. According to the embodiment, the ship information management apparatus 720 can communicate directly with the ships 700, 702, 704 without passing through the shipping companies 710, 712, receive the ship report, or transmit / receive various necessary information.

The types of ship reports received by the ship information management apparatus 720 include a departure report to be created when departing from the port, a noon report to be made at the port or at the time of departure, (ab-log), and the like. Examples of flight information included in various ship reports are various information related to fuel consumption, amount of CO ₂ emitted, travel distance, travel time, location, total amount of cargo, weight and energy efficiency. The vessels 700, 702 and 704 can collect information related to the fuel consumption through a BDN (Bunker Delivery Note), a stock tank inspection using a flow meter, and a fuel oil monitoring. The vessels 700, 702, and 704 can receive various types of flight information such as fuel consumption from an administrator, or automatically collect information acquired through various sensors and generate a ship report.

Not only are there different types of ship reports or data types used for shipping companies (710, 712), but also different types of document editors used to build ship reports. For example, the ships 700 and 702 belonging to the first marine shipping company 710 create and report various marine reports using MS-WORD, and the marine vessel 704 belonging to the second marine shipping company 712 uses PDF To prepare a ship report.

The ship information management apparatus 720 automatically recognizes texts of various characters or numbers included in ship reports of different forms received from the ship shipping companies 710 and 712, Generate and report standard reporting documents. A specific configuration related to this will be described in Fig.

8 is a view showing another example of the ship information management apparatus according to the embodiment of the present invention.

8, the ship information management apparatus 720 includes a receiving unit 800, a converting unit 810, an extracting unit 820, a standardizing unit 830, a transmitting unit 840, a local database 850, .

The receiving unit 800 receives various ship reports including the fuel usage amount from the shipping company or the ship and stores the received reports in the local database 850. Here, the ship report can be a document file created by various document editors (e.g., MS-Word, Excel, etc.), a standard pseudo electronic document file (for example, PDF) converted from a document file created by a document editor, (E. G., JPG, bitmap, etc.).

For example, the ships 700, 702, and 704 create various ship reports using MS-Word and then transmit them to e-mail providers 810 and 812 through e-mail. The shipping companies 710 and 712 send MS-Word as standardized electronic documents And can transmit the converted information to the ship information management apparatus 720. Or ships 700, 702 and 704 create a ship report using standardized electronic documents such as PDF and transmit them to marine shipping companies 710 and 712, the marine shipping companies 710 and 712 transfer the marine report directly to the ship information management device 720 . As another example, the vessels 700, 702, and 704 and the shipping companies 710 and 712 can transmit the ship report to the ship information management apparatus 720 as an image.

The converting unit 810 converts the received ship report into an image. For example, when the ship report received by the receiving unit 800 is a PDF file, the converting unit 810 converts the PDF file into an image file. If the received ship report is already an image file, the conversion unit 810 can be omitted. As another example, when the received ship report is a document file created by various document editors (that is, an MS-Word file or the like), the conversion unit 810 converts the document into an image file. At this time, the conversion unit 810 must have a corresponding document editor or a separate viewer tool to read a document created by various document editors. If the types and versions of the text editors used for the shipping companies 710 and 712 are different from each other, it is inconvenient to prepare each document editor or viewer for the document editors 710 and 712. Therefore, It is desirable to receive a ship report unified into a standardized electronic document (e.g., a PDF file) or receive a ship report in an image file. In the case of receiving a ship report in a standardized electronic document, the conversion unit may have only one tool (e.g., a PDF viewer) for reading the standardized electronic document.

The extracting unit 820 extracts characters, numbers, and the like of the necessary text area from the image of the ship report, and recognizes and stores the text. To this end, the ship information management device 720 registers and stores information on the format of various ship reports of each shipping company. For example, if the shipping report of a shipping company is a document that includes data on marine technical resources, annual total fuel usage by type, data collection methodology, operating distance, and operating time, various data may be stored in a specific location exist. Therefore, the ship information management apparatus 120 can acquire information (for example, coordinates of (x1, y1, x2, y2)) related to the position of various data included in each type of ship report of each ship shipping company and a code (I.e., a data identification code).

The extracting unit 820 extracts the area where data exists from the image of the ship report based on the form information (coordinate values and the like) corresponding to the ship report type of each ship shipping company, . Since there are a variety of conventional character recognition tools for recognizing various letters, numbers and the like included in the image, a further description thereof will be omitted. In the case where the positional information of each data in the document is defined as a coordinate value, the converting unit 810 preferably converts the ship report into an image of a normalized size in order to extract an accurate region.

The extracting unit 820 stores the recognized text in the local database 850 together with the data identification code. The types of ship reports produced by each ship may be different, but the types of ship information such as the fuel usage collected for reporting to international organizations are the same, so the data identification code indicating the data is the shipping company or vessel report Regardless of the type of the ink.

For example, if the various ship reports received from various shipping companies include fuel usage, the extractor 820 maps the text of the fuel usage to a common data identification code and stores it in the local database 850. If it is necessary to fill in the fuel usage data in various standard report documents, the standardization unit 830, which will be described later, finds the text stored in the local database together with the data identification code indicative of the fuel consumption, and writes it in the standard report document.

The standardization unit 830 generates a standard report document conforming to the standard format required by the various reporting systems 730 and 732 using the 'data identification code-text' extracted and stored from the ship report. Standard reporting documents can be MS-WORD, PDF, XML, or a document written in a separate, specified document editor. For example, if the standard reporting document includes information such as fuel usage, operating time, etc., the normalizing unit 830 may determine that the local database 850 is based on the data identification code representing each data included in the corresponding standard reporting document, And inserts the text into the corresponding position of the standard report document.

The transmitting unit 840 transmits the generated standard report document to the reporting systems 730 and 732.

9 is a view illustrating an example of a ship information management method according to an embodiment of the present invention.

Referring to FIG. 9, when the ship information management device receives the ship report (S900), it converts it into an image (S910). The ship information management apparatus extracts the area where each data exists from the image of the ship report (S920, S930), using the format information about the stored data location for each type of ship report of each ship shipping company.

The ship information management apparatus recognizes text such as letters and numbers written in the area extracted from the image by using a character recognition tool (S940). Then, the ship information management apparatus stores the text together with the data identification code in the local database (S950).

The ship information management apparatus generates a standard report document using the text stored in the local database (S960). For example, the ship information management apparatus identifies the data identification code of each data to be described in the standard report document, and then searches the local database for the corresponding text and inserts the text into the standard report document.

10 is a view illustrating a process of generating various standard report documents based on a ship report according to an embodiment of the present invention.

10, the ship information management apparatus recognizes the locations of various data included in the ship report 1000, recognizes texts 1012, 1014, and 1016 such as letters and numbers displayed at corresponding positions, (1011, 1013, 1015).

For example, when it is assumed that the fuel consumption, the operating distance, and the operating time are present in the vessel report 1000, the vessel information management apparatus analyzes the image of the vessel report 1000 and displays the first text 1012 The second text 1014 indicating the navigation distance, and the third text 1016 indicating the navigation time, and recognizes the first to third data identification codes 1011 , 1013, 1015).

When the first standard report document 1020 includes the data of the fuel usage amount and the operating time according to a predetermined form, the marine information management apparatus displays the first data identification code 1011 indicating the fuel usage amount and the operating time, The first text 1012 and the third text 1014 corresponding to the data identification code 1015 are grasped and inserted into the first standard report document 1020. The second standard report document 1030 finds and inserts the texts 1014 and 1016 of the corresponding data identification codes 1013 and 1015 when the first standard report document 1020 is different from the form or data included therein.

11 is a view showing an example of a ship information collecting apparatus according to an embodiment of the present invention.

Referring to FIG. 11, an information collecting apparatus located on a ship includes a data collecting unit 1120 and a transmitting unit 1130.

The ship is provided with an AMS (Alarm Mornitoring System) 1102 for collecting the ship dangerous condition, a VDR (Video Display Recorder) 1104 for collecting the ship motion state, various CAN devices 1108 connected via a CAN (Control Area Network) And various devices 1100 such as a GPS 1106 for determining a position.

The data collection unit 1120 uses a plurality of threads 1110 to collect data in parallel from the various devices 1100 in the ship. For example, the first to fourth threads 1112, 1114, 1116, and 1118 are connected to the AMS 1102, the VDR 1104, the GPS 1106, and the CAN device 1108, respectively, . And may further include a separate converter 1109 for communicating with the CAN device 1108 when the data collector 1120 uses the TCP / IP or UDP protocol.

The AMS 1102 and the VDR 1104 may store data using a network drive or a Universal Naming Convention (UNC). The data collection unit 1110 may store data newly stored from the AMS 1102, the VDR 1104, And to prepare a ship report.

The transmission unit 1130 transmits the generated ship report including the data collected by the data collection unit 1120 to the shipping company or the ship information management apparatus.
