[0024] Embodiment

[0025] Please refer to Figures 1 to 3 As shown, the present invention discloses a shipping evaluation method based on ship types, including the following steps:

[0026] S1. Construct a route planning area and edit the infrastructure within the route planning area;

[0027] S2. Collect the environmental data of the route planning area and evaluate the navigation environment;

[0028] S3. Obtain the freight volume, traffic flow information and route throughput information within the route planning area, and analyze and generate regional traffic condition data;

[0029] S4. Obtain the information of transportation ships, analyze and statistically process the information of transportation ships through a fine-grained spatial range, and generate regional ship driving behavior data;

[0030] S5. Based on the route planning area, perform multi-dimensional analysis on the navigation environment, regional traffic condition data and regional ship driving behavior data through a set of navigation operator models, and generate a route planning report.

[0031] The route planning area is the area used for analysis in route planning. Both the route planning area and the infrastructure are added, modified or deleted through the built-in drawing tool. The main types of the route planning area include waterways, and the main types of the infrastructure include buildings within the planning area, buildings and structures spanning and crossing waterways.

[0032] The planning scope of the waterway includes the distribution, starting and ending points, navigable mileage, and technical grade of each waterway. The waterway includes two groups: planned waterways and current waterways. The numerical value after grouping represents the number of waterways within the group. Each waterway is also a grouping object. The waterway grouping contains associated waterway areas and infrastructure areas. Each type of area supports functions such as color configuration, hiding and displaying, modification, and deletion. The waterway and the internal infrastructure have a logical association relationship and do not require a strict spatial inclusion relationship.

[0033] The subtypes of buildings within the planned area include ports, docks, shipyards, and shipbuilding platforms, etc. The identification scope includes the layout and foundation conditions.

[0034] The subtypes of buildings and structures spanning or crossing waterways include bridges, tunnels, pipelines, and cables, etc. The identification content includes navigation technical standards such as navigation layout, navigable clearance height, net width, navigable water level, and burial depth.

[0035] Environmental data includes electronic nautical charts, meteorology, and hydrology. Electronic nautical charts include information such as navigation aids, electronic fences, water depth, and waterways. Meteorology includes data and schematic diagrams of air pressure, air temperature, sea breeze, wind field, ocean current, rainfall, typhoon, etc. Hydrology includes data and schematic diagrams of tides, water flow, sea waves, ocean currents, water levels, etc.

[0036] Freight volume and traffic flow information includes freight volume analysis information, waterway cargo flow density maps, navigable berthing density analysis information, and navigable traffic density analysis information. Freight volume analysis is the development status of the freight volume of each waterway within the region in the past 3 years and the changes in the composition of freight volume by cargo type, mainly including the freight volume analysis parameter table and the freight volume analysis result output table. The waterway cargo flow density map calculates the freight volume of the main waterways by dividing into fine-grained grids and in a parallel manner, according to the freight volume by cargo type and the transportation organization method. Navigable berthing density analysis calculates the berthing density for each grid and two trajectory points by dividing into fine-grained grids and in a parallel manner, and navigable traffic density analysis calculates the traffic density for each grid and two trajectory points by dividing into fine-grained grids and in a parallel manner.

[0037] Waterway throughput information includes the total regional throughput, port throughput, and waterway throughput. The total regional throughput is the total volume of the planned area, as well as the sub-volumes corresponding to different regions for ports, waterways, or waterway groups. Port throughput is the growth of the regional port cargo throughput in the past 3 years, the composition by cargo type, and the domestic and foreign trade, import and export transportation situations. Waterway throughput is the growth of the cargo throughput of a waterway or waterway group in the past 3 years, the composition by cargo type, and the domestic and foreign trade, import and export transportation situations.

[0038] The analysis and statistics of transportation ship information include the statistics of ship types navigating in waterways, the basic situation of sailing ships, the ship type analysis information of ships, the grid analysis information of navigating ship types, the grid analysis information of navigating ship speeds, and the analysis information of temporary navigation areas. The statistics of ship types navigating in waterways are the density of ships arriving at ports by port area and waterway in the past three years, classified by ship type and load composition. The basic situation of sailing ships is the change in the inventory of transportation ships in relevant waters in the past three years, including the number of ships, net deadweight tons, total passenger capacity, average load, and the inventory of specialized ships. The ship type analysis of ships includes the change in ship types of major cargoes in recent years and the current main transportation ship types and operation and organization methods. The change in ship types of major cargoes in recent years is the statistics of ship types in the region by grid, and a change table of the number of ships of major cargo ship types is made annually, quarterly, and monthly. The main transportation ship types include cargo ships, container ships, oil tankers, fishing boats, passenger ships, etc. The main operation and organization methods include domestic trade, foreign trade, etc. The grid analysis of navigating ship types calculates the ship type situation for each grid and two trajectory points in parallel by dividing into fine-grained grids. The grid analysis information of navigating ship speeds calculates the ship speed distribution for each grid and two trajectory points in parallel by dividing into fine-grained grids. The analysis of temporary navigation areas is input by dimensions of space, time, and ship set (classified by ship type, company, and load), and combined with other information, a selective dimension analysis of the global temporary area is carried out. The supported dimensions include the basic information of sailing ships, the grid analysis of ship types in the navigation area, the grid analysis of ship speeds in the navigation area, etc.

[0039] The set of shipping operation models includes a fusion perception model operator, a regional traffic flow model operator, a port and shipping operation model operator, and a bulk commodity model operator; the fusion perception model operator is used for in-depth processing and analysis of data collected by perception devices such as AIS in a specific area; the regional traffic flow model operator is used for the analysis of the sailing route characteristics of ships and the AIS signal traffic flow in the region; the port and shipping operation model operator is used for a comprehensive assessment of the throughput capacity, efficiency level, and operation quality of different shipping lines of the port in terms of port efficiency, container capacity, and shipping line operation; the bulk commodity model operator is used to obtain the dynamics and trends of the bulk commodity market, optimize procurement and sales strategies, improve shipping logistics efficiency, and reduce shipping operation costs.

[0040] The fusion perception model operator has the function of evaluating regions, which can help us determine the geographical scope that needs to be analyzed. After that, the processing operator will clean, organize, and transform the original data to improve the quality and readability of the data. The data quality analysis operator conducts a detailed inspection of the processed data to ensure the integrity, accuracy, and consistency of the data. This can prevent errors or abnormal data from having a negative impact on the analysis results. Secondly, the processing efficiency analysis operator can evaluate the efficiency and resource utilization of the data processing process, helping us identify areas that can be optimized and improving the speed and efficiency of data processing. The correlation operator organically correlates different sources of data through comprehensive analysis, enabling us to understand the story behind the data more comprehensively and accurately. Finally, the AIS coverage function item can measure the coverage range and signal quality of AIS devices to ensure the efficiency and accuracy of the data collection process.

[0041] The regional traffic flow model operator first evaluates the target region to understand the main shipping lanes and routes of ships in the region, as well as the navigation patterns of different types of ships in the region. Secondly, using the ship dynamic information contained in the AIS signal, it extracts and analyzes the specific navigation trajectories of ships in the region to obtain the typical route characteristics of different ship types in the region. Finally, by statistically analyzing the spatial and temporal distribution of AIS signals in the region, it draws a distribution map of the AIS traffic flow in the region to understand the variation rules of ship traffic in different waters and at different times in the region.

[0042] The port and shipping operation model operator consists of functions such as the port analysis operator, container analysis operator, and shipping route analysis operator. The port analysis operator calculates the daily and monthly throughput capacity of the port, the average berthing time, and the throughput ratio of ships of different fleet sizes by extracting fields such as the ship arrival and departure times and container throughput in the AIS data, providing a reference for port planning; the container analysis operator focuses on statistically presenting the quantity distribution of different container specifications and container operation types in a certain port, as well as the changes and rules of container flow directions on the main shipping routes. This helps the port understand the container inventory status, predict peak demand, and conduct warehousing planning; the shipping route analysis operator evaluates the operation quality and market potential of different shipping routes by analyzing the change trends of the fleet size, voyage frequency, and container throughput on a certain shipping route over the years, providing a basis for shipping companies to formulate a reasonable shipping route network plan.

[0043] The route planning report integrates and displays contents such as the navigable area, navigable environment, and shipping analysis, including the ship type analysis schematic diagram and ship length analysis schematic diagram of the navigable area.

[0044] The bulk commodity model operator is a set of analysis algorithms for the trade flow of bulk commodities, aiming to provide comprehensive trade data and decision-making support. The algorithm mainly includes trade flow operators for major bulk commodities such as the iron ore cargo flow operator, the coal cargo flow operator, and the LNG cargo flow operator. The iron ore cargo flow operator analyzes the shipment, arrival, flow, and mine data of iron ore to understand the supply chain situation of iron ore and provide decision-making support for aspects such as iron ore procurement, transportation, and sales. The coal cargo flow operator comprehensively analyzes the shipment, arrival, and flow data of domestic and foreign coal trade to comprehensively understand the supply and demand situation of the coal market and provide data support for coal trade and logistics planning. The LNG cargo flow operator processes and analyzes the shipment, arrival, and flow data of LNG to master the dynamics of the LNG market and provide data support for decisions such as LNG procurement, transportation, and sales.
