[0032] The embodiments of the present application provide a cruise transport route optimization method and system based on artificial intelligence, thereby solving the problem of insufficient accuracy in route selection in the prior art. By screening and analyzing historical data, efficient routes can be quickly identified, thereby achieving the effect of improving the accuracy of route selection.

[0033] The technical solution in the embodiment of the present application is to solve the above-mentioned problem of insufficient accuracy in route selection, and the overall idea is as follows:

[0034] A route is screened out based on historical data through the geographic information system on the cruise ship. The geographic information system on the cruise ship collects the cruise transport data and the ocean weather data of the route, analyzes the cruise transport data and the ocean weather data of the route, sets the cruise transport assessment threshold and the ocean weather assessment threshold, compares the cruise transport assessment index and the ocean weather assessment index of the route with the cruise transport assessment threshold and the ocean weather assessment threshold respectively, and determines whether to optimize the route based on the comparison results. If the route does not need to be optimized, select the route for navigation. If the route needs to be optimized, comprehensively evaluate the cruise transport assessment index and the ocean weather assessment index of the route to obtain the comprehensive assessment index of the route, and optimize the route based on the comprehensive assessment index of the route, thereby achieving the effect of improving the accuracy of route selection.

[0035] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0036] like Figure 1 As shown, it is a flow chart of a cruise transport path optimization method based on artificial intelligence provided by an embodiment of the present application. The method is applied to a cruise transport path optimization system based on artificial intelligence. The method includes the following steps: S1. The geographic information system on the cruise ship selects a route based on historical data. S2. The geographic information system on the cruise ship collects the cruise transport data of the route and the ocean weather data of the route, analyzes the cruise transport data of the route and the ocean weather data of the route, and obtains the cruise transport evaluation index of the route and the ocean weather evaluation index of the route. S3. Set a cruise transport evaluation threshold and an ocean weather evaluation threshold, compare the cruise transport evaluation index of the route and the ocean weather evaluation index of the route with the cruise transport evaluation threshold and the ocean weather evaluation threshold respectively, and judge whether to optimize the route according to the comparison result. S4. If the route does not need to be optimized, select the route for navigation. If the route needs to be optimized, comprehensively evaluate the cruise transport evaluation index and the ocean weather evaluation index of the route to obtain the comprehensive evaluation index of the route, and optimize the route according to the comprehensive evaluation index of the route.

[0037] In this embodiment, based on the historical waterway data, multiple routes with the shortest historical navigation time, the lowest fuel consumption rate, the highest historical navigation speed and the largest number of emergency refuge ports during navigation are screened out. First, two routes with the least number of extreme weather events on the historical routes are selected, and then the route with the highest visibility on the sea during the historical navigation is selected from these two routes as the most frequently used and efficient route. According to the analysis results, the geographic information system selects one or several alternative routes as the preliminary navigation plan, analyzes the collected data, and predicts the transportation efficiency and possible weather impact of the route. According to the analysis results, the cruise transport assessment index and the ocean weather assessment index are calculated. If both indexes are higher than the threshold, it is considered that the current route does not need to be optimized. If any index is lower than the threshold, it is considered that the route needs to be optimized. According to the comprehensive assessment index, the system will propose a route adjustment plan, which may include changing the route, adjusting the navigation speed, and choosing a more suitable departure time.

[0038] Furthermore, the specific selection process of the geographic information system on the cruise ship to select a route based on historical data is as follows: collecting historical navigation data and historical ocean weather data of the route, selecting multiple available routes based on the historical navigation data of the route, and selecting a route with the largest historical ocean weather data among the multiple available routes based on the size of the historical ocean weather data of the route. The historical data includes the historical navigation data and historical ocean weather data of the route.

[0039] In this embodiment, historical waterway data and historical ocean weather data are collected through an API interface, database access or other data transmission methods, the collected data are cleaned and normalized, and the cruise ship's geographic information system is used to screen out multiple routes with the shortest historical navigation time, the lowest historical navigation fuel consumption rate, the highest historical navigation speed and the largest number of emergency refuge ports during navigation based on the historical waterway data. The historical ocean weather data of each available route is analyzed to evaluate its weather risk and navigation safety. Among the multiple available routes, the multiple routes are arranged in descending order according to the number of occurrences of extreme weather events on the historical routes, and then the route with the highest visibility on the sea during the historical navigation is selected in reverse order from the multiple routes arranged in descending order as the most stable route with the lowest risk, thereby avoiding the selection of these high-risk routes and improving the safety of navigation.

[0040] Historical navigation data includes historical navigation time and the number of emergency ports of refuge during historical navigation.

[0041] Historical ocean weather data includes the number of extreme weather events on historical routes and sea visibility during historical voyages.

[0042] Furthermore, the specific collection process of the cruise ship's GIS collecting cruise ship transport data and ocean weather data of the route is as follows: the cruise ship collects cruise ship transport data of the route through the GIS, and the cruise ship transport route data of the route includes cruise ship transport sailing time, cruise ship transport speed, cruise ship load and cruise ship fuel consumption rate. The cruise ship's GIS collects ocean weather data of the route through meteorological satellites, and the ocean weather data of the route includes the wind speed of the route, the air pressure of the route, the temperature of the route and the wave height of the route.

[0043] In this embodiment, the cruise ship's geographic information system is integrated with the cruise ship's navigation system, sensors and other monitoring equipment to collect the cruise ship's transportation data in real time, monitor the cruise ship's sailing time, speed, load and fuel consumption rate and other key indicators in real time, and the cruise ship's geographic information system is connected to the data service of meteorological satellites to obtain real-time ocean weather information, and collect ocean weather data closely related to navigation safety, including wind speed, air pressure, temperature and wave height. By collecting and analyzing cruise ship transportation data and ocean weather data in real time, potential risks, such as severe weather conditions or cruise ship performance problems, can be identified in a timely manner, so that measures can be taken to ensure navigation safety.

[0044] Furthermore, the specific analysis process of analyzing the cruise transport data of the route and the ocean weather data of the route is: the local processor of the cruise ship analyzes the cruise transport data of the route to obtain the cruise transport evaluation index of the route, and the geographic information system of the cruise ship analyzes the ocean weather data of the route to obtain the ocean weather evaluation index of the route.

[0045] In this embodiment, the collected cruise transport data and ocean weather data are cleaned and standardized to ensure data quality, key features such as sailing time, speed, load and fuel consumption rate are extracted from the cruise transport data and ocean weather data, the above key features are analyzed, and the cruise transport evaluation index and the ocean weather evaluation index are calculated to reflect the transport performance of the cruise on the current route and the impact of ocean weather on navigation. Combining the two evaluation indexes can more effectively plan routes, select the optimal transportation path, and reduce unnecessary risks and costs.

[0046] The cruise ship's local processors include a geographic information system and a cruise shipping route optimization system.

[0047] Furthermore, the specific process of obtaining the cruise transport assessment threshold and the ocean weather assessment threshold is as follows: the cruise ship's geographic information system analyzes the cruise ship's historical assessment threshold and the ocean weather historical assessment threshold, directly extracts the cruise ship's geographic information system and the ocean weather assessment threshold, tests the cruise ship's transport assessment threshold and the ocean weather assessment threshold in a simulated environment, analyzes the test results, and optimizes the cruise ship's transport assessment threshold and the ocean weather assessment threshold according to the test analysis results.

[0048] In this embodiment, historical evaluation threshold data of cruise transportation and ocean weather are extracted from the cruise ship's geographic information system, the historical evaluation thresholds are analyzed, the effectiveness of the threshold settings and potential improvement points are identified, the standards for the cruise transportation and ocean weather evaluation thresholds are determined based on the analysis results, the current cruise transportation evaluation thresholds and ocean weather evaluation thresholds are extracted from the geographic information system, the cruise transportation evaluation thresholds and ocean weather evaluation thresholds are tested in a simulation environment, the performance of the cruise ship under different threshold settings is observed, the results of the simulation test are analyzed, the impact of the threshold setting on the optimization of the cruise transportation path is evaluated, and the cruise transportation evaluation thresholds and ocean weather evaluation thresholds are dynamically adjusted within the threshold range based on the results of the simulation test. The threshold range is directly obtained through the database, and the dynamic adjustment rule is to increase or decrease the cruise transportation evaluation threshold and the ocean weather evaluation threshold based on the results of the simulation test combined with the threshold range. The simulation test and threshold adjustment process are repeated until the evaluation thresholds of the cruise transportation evaluation index and the ocean weather evaluation index with the smallest difference from the cruise transportation evaluation threshold and the ocean weather evaluation threshold are found. By analyzing historical data, the evaluation thresholds can be set more accurately to ensure that the thresholds are consistent with the actual situation.

[0049] Furthermore, the specific judgment process for determining whether to optimize the route based on the comparison results is: comparing the cruise transport assessment index of the route and the ocean weather assessment index of the route with the cruise transport assessment threshold and the ocean weather assessment threshold respectively; if the cruise transport assessment index of the route is greater than or equal to the cruise transport assessment threshold and the ocean weather assessment index of the route is greater than or equal to the ocean weather assessment threshold, the route does not need to be optimized; in other cases, the route needs to be optimized.

[0050] In this embodiment, the cruise ship's geographic information system is used to obtain the cruise ship's current route's cruise ship transport assessment index and ocean weather assessment index, and the cruise ship transport assessment index is compared with the cruise ship transport assessment threshold, and the ocean weather assessment index is compared with the ocean weather assessment threshold. If the cruise ship transport assessment index of the route is greater than or equal to the cruise ship transport assessment threshold, and the ocean weather assessment index is greater than or equal to the ocean weather assessment threshold, then the route is considered safe under current conditions and does not need to be optimized. If any of the assessment indexes is lower than the corresponding assessment threshold, then the route is considered to have potential risks or efficiency issues and needs to be optimized. By comparing the assessment index and the threshold, it can be ensured that the route meets the predetermined standards in terms of safety and efficiency, thereby ensuring the safety of passengers and crew members.

[0051] Furthermore, the specific evaluation process of comprehensively evaluating the cruise transport assessment index and the ocean weather assessment index of the route is as follows: standardizing the cruise transport assessment index and the ocean weather assessment index, determining the influence weights of the cruise transport assessment index and the ocean weather assessment index of the route, and conducting a comprehensive evaluation to obtain the comprehensive evaluation index of the route.

[0052] In this embodiment, the cruise transport assessment index and the ocean weather assessment index are normalized by the minimum-maximum normalization method or the Z-score normalization method to make them in the same dimension, usually by scaling the data to between 0 and 1, and determining the size relationship between the weights of the cruise transport assessment index and the ocean weather assessment index through historical data analysis. For example, the wind direction of the route is obtained from the database. If the wind direction is opposite to the route, the weight of the ocean weather assessment index is greater than that of the cruise transport assessment index. The standardized cruise transport assessment index and ocean weather assessment index are multiplied by their respective weights, and then summed to obtain the comprehensive assessment index of the route. Through standardization, the comparability between different indicators is ensured, and the accuracy of the comprehensive evaluation is improved.

[0053] Furthermore, the specific optimization process of optimizing the route according to the comprehensive evaluation index of the route is: comparing the cruise transport evaluation index and the ocean weather evaluation index in the comprehensive evaluation index of the route with the cruise transport evaluation threshold and the ocean weather evaluation threshold, and obtaining the comparison results of the cruise transport evaluation index and the ocean weather evaluation index with the cruise transport evaluation threshold and the ocean weather evaluation threshold, optimizing the route or cruise according to the comparison results, including opening the cruise ship's stabilizing fins, opening the cruise ship's energy recovery system and readjusting the path, comprehensively evaluating the optimized route to obtain the comprehensive evaluation index of the optimized route, storing the comprehensive evaluation index of the optimized route in the cloud, and providing a reference for the next route based on the comprehensive evaluation index of the optimized route stored in the cloud.

[0054] In this embodiment, the cruise ship transport assessment index and the ocean weather assessment index in the comprehensive assessment index of the route are compared with the cruise ship transport assessment threshold and the ocean weather assessment threshold. If the ocean weather assessment index in the comprehensive assessment index is lower than the ocean weather assessment threshold and the cruise ship transport assessment index is greater than or equal to the cruise ship transport assessment threshold, the route is not modified, and the cruise ship's stabilizing fins are opened to reduce the swaying of the ship by reducing the speed. In the case of large winds and waves, the stabilizing fins can significantly improve the stability of navigation. If the ocean weather assessment index is greater than or equal to the ocean weather assessment threshold and the cruise ship transport assessment index is lower than the cruise ship transport assessment threshold, the route is not modified, the cruise ship's energy recovery system is turned on, the cruise ship is energy recovered, and the consumption of the cruise ship's voyage is reduced. If the ocean weather assessment index is lower than the ocean weather assessment threshold and the cruise ship transport assessment index is lower than the cruise ship transport assessment threshold, the sea conditions and weather changes are monitored in real time, the route path is adjusted to avoid high-risk routes, and the speed is adjusted according to the current sea conditions and weather forecasts to ensure the safety and efficiency of cruise transportation.

[0055] After the route is optimized, the specific effects of the comprehensive evaluation index of the route are as follows: (1) Comprehensively evaluate the optimized route to obtain the comprehensive evaluation index of the optimized route. (2) Obtain the comprehensive evaluation threshold of the optimized route directly from the database. (3) Compare the comprehensive evaluation index of the optimized route with the comprehensive evaluation threshold of the optimized route. The specific comparison process of the comprehensive evaluation index of the optimized route and the comprehensive evaluation threshold of the optimized route is as follows: if the comprehensive evaluation index of the optimized route is greater than or equal to the comprehensive evaluation threshold of the optimized route, the comprehensive evaluation index of the optimized route is stored in the cloud server. When the same route is sailed next time, the comprehensive evaluation index of the optimized route stored in the cloud server is used as a reference for the next route planning, which significantly improves the scientific nature of safe navigation. By storing the comprehensive evaluation index of each route, a large amount of historical data can be accumulated to provide rich reference information for subsequent route optimization. The stored evaluation index allows cruise companies to quickly adjust routes in the face of sudden weather changes or other emergencies, thereby improving the flexibility of responding to emergencies. If the comprehensive evaluation index of the optimized route is less than the comprehensive evaluation threshold of the optimized route, the cloud server refuses to store the comprehensive evaluation index of the optimized route, which improves the rigor of using historical route data as a reference. This system stores the comprehensive evaluation index of all sea routes, which will be used for reference by cruise ships in the future. The system will give priority to cruise ships of the same tonnage.

[0056] If the cruise ship has not optimized its route and only turned on its stabilizing fins or energy recovery system, there is no optimized comprehensive evaluation index at this time. At this time, the comprehensive evaluation index of the original route is compared with the comprehensive evaluation threshold of the original route obtained from the database. If the comprehensive evaluation index of the original route is greater than or equal to the comprehensive evaluation threshold of the original route, the comprehensive evaluation index of the original route is stored in the cloud server. If the comprehensive evaluation index of the original route is less than the comprehensive evaluation threshold of the original route, the cloud server refuses to store the comprehensive evaluation index of the original route.

[0057] Furthermore, the specific method for obtaining the comprehensive evaluation index of the route is:

[0058]

[0059] Wherein, ε represents the comprehensive evaluation index of the route, which is used to evaluate the impact of cruise transport and ocean weather on the route, μ represents the cruise transport evaluation index of the route, α represents the impact weight of the cruise transport evaluation index of the route, ρ represents the ocean weather evaluation index of the route, β represents the impact weight of the ocean weather evaluation index of the route, ΔTH represents the distance deviation between the cruise ship's sailed path and the original planned path, ΔLP represents the fuel consumption deviation between the cruise ship's sailed path and the original planned path, ΔCV represents the wind direction angle deviation between the cruise ship's sailed path and the original planned path, and θ represents the impact weight of the distance deviation, fuel consumption deviation and wind direction angle deviation between the cruise ship's sailed path and the original planned path on the comprehensive evaluation index of the route.

[0060] The distance deviation value between the cruise ship's sailed path and the original planned path will change with the cruise ship's transport speed. The greater the difference between the cruise ship's transport speed and the cruise ship's transport speed reference value, the greater the distance deviation value between the cruise ship's sailed path and the original planned path. The fuel consumption deviation value between the cruise ship's sailed path and the original planned path will change with the cruise ship's fuel consumption rate. When the cruise ship's fuel consumption rate is greater, the fuel consumption deviation value between the cruise ship's sailed path and the original planned path is greater. The wind direction angle deviation value between the cruise ship's sailed path and the original planned path will change with the wind speed of the route. When the wind speed of the route is greater, the wind direction angle deviation value between the cruise ship's sailed path and the original planned path is greater.

[0061] The distance deviation value between the cruise ship's sailed path and the original planned path can be obtained in real time through the global positioning device installed on the cruise ship, the fuel consumption deviation value between the cruise ship's sailed path and the original planned path can be obtained through the fuel consumption monitoring system on the cruise ship, and the wind direction angle deviation value between the cruise ship's sailed path and the original planned path can be directly obtained through meteorological satellites.

[0062] The weight of the cruise transport evaluation index of the route, the weight of the ocean weather evaluation index of the route, and the weight of the distance deviation between the cruise ship's sailed path and the original planned path, the fuel consumption deviation value, and the wind direction angle deviation value on the comprehensive evaluation index of the route can be obtained through the dynamic information database, and the weight of the cruise transport evaluation index of the route, the weight of the ocean weather evaluation index of the route, and the weight of the distance deviation between the cruise ship's sailed path and the original planned path, the fuel consumption deviation value, and the wind direction angle deviation value on the comprehensive evaluation index of the route can also be obtained through the reciprocal of the sum of the cruise transport evaluation index of the route, the ocean weather evaluation index of the route, and the distance deviation between the cruise ship's sailed path and the original planned path, the fuel consumption deviation value, and the wind direction angle deviation value in the historical data. A mapping set of cruise transport evaluation index of the route, ocean weather evaluation index of the route and the inverse of the sum of the distance deviation value, fuel consumption deviation value and wind direction angle deviation value between the cruise ship's sailed path and the original planned path and their corresponding weights are established respectively with the relationship between the dynamic information; by inputting the real-time cruise transport evaluation index of the route, ocean weather evaluation index of the route and the inverse of the sum of the distance deviation value, fuel consumption deviation value and wind direction angle deviation value between the cruise ship's sailed path and the original planned path, the cruise transport evaluation index influence weight of the corresponding route in the mapping set, the ocean weather evaluation index influence weight of the route and the influence weight of the distance deviation value, fuel consumption deviation value and wind direction angle deviation value between the cruise ship's sailed path and the original planned path on the comprehensive evaluation index of the route are obtained.

[0063] In this embodiment, the specific method for obtaining the cruise transport evaluation index of the route is:

[0064]

[0065] μ represents the cruise transport evaluation index of the route, sj represents the cruise transport sailing time, and sj 0 It is the reference value of cruise ship sailing time, hs is the cruise ship speed, hs 0 It is the reference value of cruise ship transport speed, zw is the cruise ship load, zw 0 It is the reference value of the cruise ship's load, hy is the fuel consumption rate of the cruise ship, hy 0 It is expressed as the reference value of cruise ship fuel consumption rate, γ represents the impact weight of cruise ship sailing time, δ represents the impact weight of cruise ship speed, σ represents the impact weight of cruise ship load, τ represents the impact weight of cruise ship fuel consumption rate, and e is expressed as a natural constant.

[0066] In this embodiment, the cruise ship transportation sailing time can be automatically recorded by the cruise ship's GPS and other navigation systems, the cruise ship transportation speed can be monitored in real time by the speed recorder on the cruise ship, the cruise ship load can be measured by the ship management system on the cruise ship, and the cruise ship fuel consumption rate can be accurately measured by the flow meter installed on each fuel pump. The reference value of the cruise ship transportation sailing time, the reference value of the cruise ship transportation speed, the reference value of the cruise ship load, and the reference value of the cruise ship fuel consumption rate can be directly obtained from the database, and the above reference values ​​are all referenced to cruise ships of the same tonnage.

[0067] The cruise transport sailing time weight, cruise transport speed influence weight, cruise load influence weight, and cruise fuel consumption rate influence weight can be obtained through the dynamic information database. Through the relationship between the cruise transport sailing time, cruise transport speed, cruise load, and cruise fuel consumption rate in the historical data and the dynamic information, a mapping set of cruise transport sailing time, cruise transport speed, cruise load, and cruise fuel consumption rate and their corresponding weights is established respectively. By inputting the real-time cruise transport sailing time, cruise transport speed, cruise load, and cruise fuel consumption rate, the corresponding cruise transport sailing time weight, cruise transport speed influence weight, cruise load influence weight, and cruise fuel consumption rate influence weight in the mapping set are obtained.

[0068] The maximum wind speed, air pressure, temperature and wave height of the route are directly obtained through the database. When any parameter of the wind speed, air pressure, temperature and wave height of the route is greater than or equal to the maximum value, the ocean weather assessment index of the route is 0. In other cases, the specific method of the ocean weather assessment index of the route is:

[0069]

[0070] ρ represents the ocean weather assessment index of the route, fs represents the wind speed of the route, and fs 0 It is the reference value of the wind speed of the route, qy is the air pressure of the route, qy 0 It is the reference value of the air pressure of the route, wd is the temperature of the route, wd 0 It is the reference value of the temperature of the route, lg is the wave height of the route, lg 0 It indicates the reference value of wave height for the route.

[0071] The wind speed, air pressure, temperature and wave height of the route can be uniformly obtained through meteorological satellites, and the reference values ​​of the wind speed, air pressure, temperature and wave height of the route can be directly obtained through the database.

[0072] According to the analysis of physical relationships, the higher the temperature of the route, the higher the air pressure of the route, and the air pressure of the route is positively correlated with the temperature of the route; the wind speed of the route affects the cruise transport speed, cruise transport sailing time and cruise fuel consumption rate synchronously according to the wind direction. When the wind direction is opposite to the route direction, the wind speed of the route has a negative impact on the cruise transport speed, cruise transport sailing time and cruise fuel consumption rate. When the wind direction is the same as the route direction, the wind speed of the route has a positive impact on the cruise transport speed, cruise transport sailing time and cruise fuel consumption rate.

[0073] In a specific embodiment, the ocean weather assessment index data of the route is exemplified in the following table.

[0075]

[0076]

[0077] E 0 =10 knots, F 0 =1013 hPa, K 0 =25 degrees Celsius, M 0 = 3 meters, through Figure 2 It can be seen from the data in Table 1 that when the air pressure, temperature and wave height of the route remain unchanged, the greater the wind speed of the route, the lower the ocean weather assessment index of the route.
