[0072] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0073] Reference Figure 1 As shown, a ship intelligent management method based on multi-source data analysis includes:

[0074] Extract environmental characteristics of different sea areas based on big data of navigation information and sea area information;

[0075] Based on the ship's hull structure, a multi-source sensor group is set at a suitable location to collect environmental data of the sea area;

[0076] According to the navigation information before being lost and the environmental characteristics of the sea area, the area is set as a first positioning information group, and the first positioning vector sequence is calculated;

[0077] According to the changes in the sea environment data and the moving distance during the movement of the ship, the information is set as the second positioning information group, and the deviation coefficient of the ship's heading is confirmed in combination with the navigation map;

[0078] Based on the neural network algorithm, a pyramid model of ship orientation positioning is established to assist in determining the ship's sailing direction and location.

[0079] It can be explained that this solution analyzes the big data of navigation information and sea area information, extracts the environmental characteristics of different sea areas, establishes the first positioning unit and the second positioning unit, and establishes the ship orientation positioning matrix required by the neural network through the first positioning unit and the second positioning unit, thereby establishing a pyramid model of ship orientation positioning to judge and locate the sailing direction and position of a lost ship.

[0080] Reference Figure 2 As shown, the setting of the area as the first positioning information group according to the navigation information before being lost and the environmental characteristics of the sea area, and calculating the first positioning vector sequence specifically includes:

[0081] Obtain navigation information and sea environment characteristics before the ship gets lost, and establish a sea environment characteristics data matrix;

[0082] According to the marine environment characteristic database, the theoretical indicators of the environmental characteristics of the area where the ship is lost are obtained;

[0083] According to the CRITIC weighting method, determine the index weight of the environmental characteristics of the sea area in the entire sea area environmental characteristics database;

[0084] According to the obtained weight index, a feature vector sequence of the environmental feature group of the sea area is established and defined as the first positioning vector sequence.

[0085] It can be explained that there are errors between the marine environment characteristic library obtained through big data and the actual marine environment conditions, and there may even be large discrepancies. Secondly, the positioning information before being lost and the environmental characteristic data of the sea area are important bases for judging the ship. This scheme analyzes the current marine environment characteristic data and the theoretical indicators of the environmental characteristics of the area where the ship is lost, and based on the CRITIC weighting method, determines the indicator weight of the environmental characteristics of the sea area in the entire marine environment characteristic library, thereby improving the accuracy of the neural network in the final result, and can adjust and optimize the parameter values ​​of the neural network. Secondly, the CRITIC weighting method is a comprehensive measure of the objective weight of the indicator based on the comparison strength of the evaluation indicators and the conflict between the indicators, and it is a scientific evaluation that fully utilizes the objective attributes of the data itself.

[0086] Reference Figure 3 As shown, according to the change of the sea environment data and the moving distance during the movement of the ship, the information is set as the second positioning information group, and the deviation coefficient of the ship's heading is confirmed in combination with the nautical map, which specifically includes:

[0087] Obtaining the sea environment data changes, moving distance and navigation information during the movement of the ship before the ship is lost, and setting the information as the second positioning information group;

[0092] In the formula, Z s is the deviation coefficient of the ship’s heading, X i is the matrix data of the second positioning information group in the i-th row and j-th column, is the specific coordinate information of the nautical map, and N is the number of different information types in the second positioning information group matrix.

[0093] It can be explained that nautical charts are an important tool to help ships navigate. Existing nautical charts have high accuracy for fixed and frequently navigated areas. In the absence of any navigation equipment, the actual sailing direction will deviate, causing the ship to deviate from the course. Therefore, this solution calculates the deviation coefficient of the ship's heading by analyzing the specific coordinate information of the nautical map and the second positioning information group of the current position, thereby improving the subsequent training and judgment accuracy of the neural network.

[0094] Reference Figure 4 As shown, the pyramid model of ship orientation positioning based on the neural network algorithm is established to assist in determining the navigation direction and location of the ship, which specifically includes:

[0095] Establishing a ship orientation positioning matrix according to the first positioning vector sequence and the deviation coefficient of the ship's heading;

[0096] Based on the neural network algorithm, a pyramid model for ship orientation positioning is established;

[0097] The pyramid model based on the ship's orientation can assist in determining the ship's sailing direction and location;

[0098] The pyramid model of ship orientation positioning specifically includes:

[0099] The first level of the pyramid model is: collecting environmental data of the sea area through a multi-source sensor group;

[0100] The second layer of the pyramid model is: denoising and normalizing the collected data through the Kalman filter algorithm and data normalization formula;

[0101] The third layer of the pyramid model is: analyzing the environmental data of ship positioning and establishing the ship orientation positioning matrix;

[0102] The fourth layer of the pyramid model is: based on the ship's orientation positioning matrix and based on the neural network algorithm, it is used to assist in determining the ship's sailing direction and location.

[0103] It can be explained that this scheme, by setting up a pyramid model, processes and analyzes the data from low to high through the advanced process of data collection - data filtering and standardization - data analysis - result judgment, thereby realizing the judgment and assistance of the ship's navigation direction and position, and effectively improving the accuracy and reliability of the ship's navigation positioning.

[0104] Further, based on the same inventive concept as the above-mentioned ship intelligent management method based on multi-source data analysis, this solution proposes a ship intelligent management system based on multi-source data analysis, including:

[0105] A feature extraction module, which is used to extract environmental features of different sea areas based on big data of navigation information and sea area information;

[0106] A data acquisition module, which is used to set a multi-source sensor group at a suitable position based on the hull structure of the ship to collect environmental data of the sea area;

[0107] A direction judgment module is used to set the area as a first positioning information group and calculate the first positioning vector sequence according to the navigation information before the ship is lost and the environmental characteristics of the sea area; set the information as a second positioning information group according to the changes in the sea area environmental data and the moving distance during the movement of the ship, and confirm the deviation coefficient of the ship's heading in combination with the nautical map; and establish a pyramid model of ship direction positioning based on a neural network algorithm to assist in judging the ship's sailing direction and location.

[0108] Preferably, the orientation determination module specifically includes:

[0109] A first positioning unit, the first positioning unit is used to set the area as a first positioning information group and calculate the first positioning vector sequence according to the navigation information before being lost and the environmental characteristics of the sea area;

[0110] A second positioning unit, the second positioning unit is used to set the information as a second positioning information group according to the change of the sea environment data and the moving distance during the movement of the ship, and to confirm the deviation coefficient of the ship's heading in combination with the nautical map;

[0111] A direction determination unit is used to establish a pyramid model for ship direction positioning based on a neural network algorithm to assist in determining the ship's sailing direction and location.

[0112] In summary, the advantages of the present invention are: by analyzing the big data of navigation information and sea area information, extracting the environmental characteristics of different sea areas, establishing a first positioning unit and a second positioning unit, and establishing the ship orientation positioning matrix required by the neural network through the first positioning unit and the second positioning unit, thereby establishing a pyramid model of ship orientation positioning, judging and locating the sailing direction and position of a lost ship, assisting the ship commander to find the direction of the return trip as soon as possible, reducing the subjective error of ship positioning, and improving the ship's positioning capability and survival management capability.
