[0015] The following drawings attached to this specification illustrate a preferred embodiment of the present invention and serve to further enhance understanding of the technical concept of the present invention together with the detailed description of the invention; therefore, the present invention should not be interpreted as being limited only to the matters described in such drawings. FIG. 1 is a drawing illustrating a data collection and distribution unit of a ship according to conventional technology, and FIG. 2 is a diagram roughly illustrating the configuration of a data management device for a ship according to an embodiment of the present invention, and FIG. 3 is a diagram roughly illustrating the configuration of a protocol conversion and mapping unit according to an embodiment of the present invention, and FIG. 4 is a diagram roughly illustrating the configuration of a data merging and distribution unit according to an embodiment of the present invention, and FIG. 5 is a diagram roughly illustrating the configuration of an abnormal position data identification unit according to an embodiment of the present invention. Specific details for implementing the invention

[0016] Hereinafter, a preferred embodiment of the present invention will be described with reference to the drawings. Furthermore, the embodiment described below does not unduly limit the scope of the present invention as defined in the claims, and the entire configuration described in this embodiment is not considered essential as a means of solving the present invention. Additionally, descriptions of prior art and matters obvious to those skilled in the art may be omitted, and such omitted descriptions of components (methods) and functions may be sufficiently referenced within the scope that does not depart from the technical spirit of the present invention.

[0018] An intelligent data management device for a navigating vessel according to one embodiment of the present invention roughly includes an input interface unit (100), a data collection and distribution unit (200), and an output interface unit (300) as shown in FIG. 2.

[0020] An input interface unit (100) according to an embodiment of the present invention receives data necessary for the operation or navigation of a ship from various devices. Examples of various devices may include a navigation communication device (31), a sensor (32), and a radar (33). The navigation communication device (31) may be a GPS, AIS, an Echo Sounder, etc. The sensor (32) may be a Strain Gauge, a Roll / Pitch Gauge, etc. The radar (33) may be an image of the radar.

[0022] The input interface unit (100) receives relevant data from the aforementioned navigation communication device (31), sensor (32), and radar (33) via Ethernet, RS 232C, RS 422, and RS 485 communication. Since the navigation communication device (31), sensor (32), and radar (33) transmit data according to their respective packet protocols, the protocol conversion and mapping unit (210) described later is also required in the present invention. The ship navigation information data input through the input interface unit (100) is transmitted to the protocol conversion and mapping unit (210), data merging and distribution unit (220), data storage and transmission unit (230), and abnormal location data identification unit (240), respectively, described later.

[0024] As illustrated in FIG. 2, a protocol conversion and mapping unit (210) according to an embodiment of the present invention receives various ship navigation information data required for a navigating ship from an input interface unit (100) through a plurality of input ports. Additionally, the protocol conversion and mapping unit (210) converts the non-standard protocol of the input data into a standard protocol based on the analysis of the input data, and maps the input non-standard data to the standard protocol and outputs it. To this end, the protocol conversion and mapping unit (210) includes a protocol conversion unit (212) and a protocol mapping unit (213).

[0026] The protocol conversion unit (212) converts the non-standard protocol of the input data into a standard protocol and outputs it. However, if a standard protocol is received instead of a non-standard protocol, it outputs it exactly as received without protocol conversion. That is, as shown in the embodiment illustrated in FIG. 3, the protocol conversion unit (212) can receive 'D1' data and 'D2' data. 'D1' data is a non-standard protocol, and 'D2' data is a standard protocol. Since 'D1' data is a non-standard protocol, it is converted into a standard protocol and outputs it, and since 'D2' data is a standard protocol, it outputs it exactly as received without protocol conversion.

[0028] The protocol mapping unit (213) repositions and maps the input non-standard data to match the standard protocol and converts it into a standard protocol output. At this time, when the protocol mapping unit (213) receives a standard protocol, it outputs it exactly as received without protocol conversion. That is, as in the embodiment illustrated in FIG. 3, the protocol mapping unit (213) can receive 'D3' data and 'D4' data, where 'D3' data represents an example of a standard protocol and 'D4' data represents non-standard data. Since 'D4' data is 'binary' data and is non-standard data, the binary data is processed and mapped to match the packet configuration of the standard protocol and converted into a standard protocol output. Since 'D3' data is a standard protocol, it outputs it exactly as received without protocol conversion.

[0030] The above-described standard protocol may be, for example, the 'NMEA 0183' or 'NMEA 2000' data protocol, but the format of the standard protocol may vary, and it converts various non-standard protocols (or data of non-standard protocols) input through the input interface unit (100) into a standard protocol of the same format (or data of a standard protocol).

[0032] Data converted to a standard protocol or bypassed output from the protocol conversion unit (212) and the protocol mapping unit (213) is transmitted to the data merging and distribution unit (220) to serially merge and output the data according to conditions. That is, the data merging and distribution unit (220) receives the protocol-converted data from the protocol conversion and mapping unit (210) and serially merges the data according to conditions or bypasses and outputs it as received.

[0034] As illustrated in FIG. 4, a data merging and distribution unit (220) according to an embodiment of the present invention has a first distribution path that distributes and outputs data converted to or bypassed by a standard protocol transmitted from a protocol conversion and mapping unit (210) in a 1:N format (N is an integer greater than or equal to 1). That is, referring to FIG. 4, as an example, the first data distribution unit (222) receives 'D1' data of the standard protocol from a data input unit (221) and distributes and outputs it through two output ports. Thus, it performs a distribution structure of input 1 : output 2. However, although not illustrated in the drawing, as another example, the first data distribution unit (222) may receive 'D2', 'D3', and 'D4' respectively, and the 'D2' data may be distributed in an input 1 : output 3 structure, the 'D3' data may be distributed in an input 1 : output 2 structure, and the 'D4' data may be distributed in an input 1 : output 5 structure. Accordingly, the first data distribution unit (222) outputs data of the standard protocol transmitted from the protocol conversion and mapping unit (210) in a 1:N format through the first distribution path. The first distribution path may refer to a data input / output path including the data input port and output port of the first data distribution unit (222).

[0036] Additionally, the data merging and distribution unit (220) includes a data conditional distribution unit (223) that maps and merges selected data among multiple data converted into a standard protocol according to a pre-set condition when a pre-set condition is met or a command for data merging and distribution is received from the outside, and distributes the data through a second distribution path. That is, referring to FIG. 4, as an example, the data conditional distribution unit (223) includes a data mapping unit (224), a data merging unit (225), and a second data distribution unit (226).

[0038] The data mapping unit (224) selects data that corresponds to the set condition or external request command signal among the multiple data input from the data input unit (221) and determines the mapping order of the data. The set condition or external request command signal may be, for example, data to be merged or the serial merging order of the data. The data mapping unit (224) receives data 'D1', 'D2', 'D3', and 'D4' from the data input unit (221), selects data that corresponds to the set condition or external request command signal, and determines the mapping order of the data to correspond to the condition or command signal. Referring to FIG. 4, as an example of the first conditional distribution, the data 'D1', 'D2', 'D3', and 'D4' are serially merged and the merging order is sequentially in ascending order, and as an example of the second conditional distribution, the data 'D1' and 'D4' are serially merged and the merging order is sequentially in ascending order.

[0039] The first data distribution unit (222) described above is a structure that receives and distributes specific data in a 1:N structure, whereas the data conditional distribution unit (223) receives all data converted and output as a standard protocol from the protocol conversion and mapping unit (210), serially merges the data according to the conditions, and distributes the output.

[0041] The data merging unit (225) serially merges and connects the selected data transmitted from the data mapping unit (224) according to the data mapping order. That is, the data mapping unit (224) transmits the data to be merged that meets the conditions and the mapping order of the data to the data merging unit (225), and the data merging unit (225) serially merges the data according to the standard protocol according to the transmitted selected data and the mapping order. As an example, referring to FIG. 4, the data merging unit (225) serially merges the data 'D1', 'D2', 'D3', and 'D4' in ascending order according to the standard protocol as an example of the first conditional serial merging, and serially merges the data 'D1' and 'D4' in ascending order according to the standard protocol as an example of the second conditional serial merging.

[0043] The second data distribution unit (226) outputs multiple serial data that have been serially merged according to the first conditional serial merger and the second conditional serial merger transmitted from the data merging unit (225) along the second distribution path. In FIG. 4, one output of 'D1+D2+D3+D4' merged data and one output of 'D1+D4" merged data are exemplified as distribution outputs, but multiple identical merged data may be distributed and output.

[0044] Here, the second distribution path may refer to a data input / output path from the data input port of the data mapping unit (224) to the data output port of the second data distribution unit (226).

[0046] A data storage and transmission unit (230) according to one embodiment of the present invention records collected ship navigation information data in a connected database and transmits the collected ship navigation information data from the ship to a land base station via a wireless communication network (e.g., LTE, LTE-M).

[0048] As illustrated in FIG. 5, an abnormal position data identification unit (240) according to an embodiment of the present invention detects an anomaly (error) in the GPS data among the ship navigation information data input through the input interface unit (100) using a learning module, and continuously checks or marks the validity (valid GPS data) of the input GPS data. In addition, when an anomaly in the GPS data is detected through the learning module, the abnormal position data identification unit (240) calculates and outputs valid GPS data using a pre-set position calculation method based on the last valid GPS data.

[0050] The abnormal location data identification unit (240) includes a location data input unit (241), a location data anomaly detection unit (242), a valid location data recording unit (246), and a location data output unit (247).

[0052] The location data input unit (241) receives GPS data among the ship navigation information data from either the input interface unit (100) or the configuration module of the data collection and distribution unit (200).

[0054] The location data anomaly detection unit (242) receives GPS data from the location data input unit (241). Additionally, the location data anomaly detection unit (242) continuously detects errors in GPS data through a learning module by matching and comparing the current location estimate value calculated through a preset location calculation method based on the valid GPS data of the last marked location reference point with the current GPS data input from the input interface unit (100). To this end, the location data anomaly detection unit (242) includes a valid location estimate value calculation unit (243), a valid location estimate value matching unit (244), and an abnormal data determination unit (245).

[0056] The valid position estimate calculation unit (243) continuously calculates and updates the current valid position estimate using the position, velocity, and direction of the valid GPS data of the last marked valid position reference point. For example, if the abnormal data determination unit (245) determines that the first GPS data entered at the first time point is valid, the valid position estimate calculation unit (243) calculates the current valid position estimate of the second time point using the position, velocity, and direction values ​​included in the valid first GPS data in order to determine the validity of the second GPS data entered at the second time point. The same principle applies to the method of calculating the valid position estimate of the corresponding time point even after the third time point.

[0058] The valid position estimate matching unit (244) matches the current valid position estimate input from the valid position estimate calculation unit (243) with the current GPS data input from the position data input unit (241). That is, based on the example described above, the valid position estimate at the second time point calculated earlier is compared with the GPS data input at the second time point.

[0060] The abnormal data determination unit (245) detects and determines errors in the current valid position estimate and current GPS data through a generated learning module. In the example described above, the valid position estimate at the second time point matched by the valid position estimate matching unit (244) and the GPS data input at the second time point are compared with each other; if the preset error condition is not satisfied, it is determined that an error in the GPS data has been detected, and the information of the GPS data determined to be an error is transmitted to the valid position data recording unit (246) to be marked and recorded.

[0062] The above-described valid position estimate calculation unit (243), valid position estimate matching unit (244), and abnormal data determination unit (245) calculate and compare the current valid position estimate and the current GPS data at each point in time when GPS data is input, thereby determining whether the input GPS data is normal or abnormal. While determining the normality of the GPS data at each point in time, if the input GPS data at any point in time is abnormal, the position, velocity, and direction values ​​of the valid GPS data when it was normal immediately prior to that point in time are used to calculate the valid position estimate for the current point in time, and this is output to be used as GPS information. However, if the GPS data is input abnormally due to jamming and then returns to normal (refer to the above-described abnormal data determination unit for determining normality), the position estimate is not used, and the input GPS data value is utilized.

[0064] The valid location data recording unit (246) marks and records whether the input GPS data is 'normal or erroneous' at each GPS input time based on the error detection judgment of the GPS data by the abnormal data judgment unit (245), and updates the result.

[0066] The location data output unit (247) outputs GPS data corresponding to the calculated current location estimate when the GPS data is abnormal data, and outputs the GPS data input from the location data input unit (241) as is bypassed when the GPS data is normal.

Furthermore, the components of the present invention described above are explained only for the convenience of explaining the invention, and components not described herein may be added within the scope that does not depart from the technical spirit of the present invention.

[0070] The descriptions of the composition and function of each part mentioned above have been explained separately for the sake of convenience of explanation; however, as necessary, any one composition or function may be integrated into another component or implemented in a more subdivided manner.

[0072] Although the present invention has been described with reference to an exemplary embodiment, the invention is not limited thereto, and various modifications and applications are possible. That is, those skilled in the art will readily understand that many modifications are possible within the scope of the essence of the invention. Furthermore, it should be noted that specific descriptions of known functions and configurations related to the invention, or the combination relationships of each configuration of the invention, have been omitted if it is determined that such descriptions would unnecessarily obscure the essence of the invention.
