[0008] By adopting the above technical solution, the historical route information is first filtered by the starting month of the route, so as to quickly filter out a large amount of historical route information, and then filtered by the starting port and the ending port to obtain the candidate route information, thereby improving the efficiency of determining the candidate route information and thus improving the efficiency of route planning.

Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0026] In addition, the term "and / or" in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article, unless otherwise specified, generally means that the associated objects before and after are in an "or" relationship.

[0027] like Figure 1 As shown, a ship route planning method, the main process of the method is described as follows (steps S101 to S104): Step S101: Obtain user demand information and historical route information.

[0028] Among them, user demand information includes the starting port, the ending port and the starting time of the route. The starting time of the route includes the starting month and the starting date of the route. The historical route information is the route information corresponding to multiple historical voyages, including the historical starting port, the historical ending port, the historical starting month of the route, the sailing mileage, the sailing time, the historical sea conditions, the historical weather, the total fuel consumption, the fuel consumption per 100 nautical miles and the low-sulfur zone parameters. If the route passes through the low-sulfur zone, the low-sulfur zone parameter is 1. If the route does not pass through the low-sulfur zone, the low-sulfur zone parameter is 0.

[0029] Obtain user demand information from users and obtain historical route information from the database.

[0030] Step S102: Filter historical route information based on user demand information to obtain candidate route information.

[0031] The historical route information that meets the user's demand information is determined as candidate route information.

[0032] Specifically, historical route information is screened based on user demand information to obtain candidate route information, including: determining a historical starting port, a historical ending port and a historical route starting month based on the historical route information; determining the historical route information whose historical route starting month is the same as the route starting month as the initial candidate route information; if there is initial candidate route information whose historical starting port is the same as the starting port, and whose historical ending port is the same as the ending port, then the initial candidate route information whose historical starting port is the same as the starting port, and whose historical ending port is the same as the ending port is determined as the candidate route information.

[0033] In this embodiment, the historical starting port, historical ending port and historical route starting month of each route are searched from the historical route information, and the historical route information whose historical route starting month is the same as the route starting month in the user demand information is determined as the initial candidate route information, and it is judged whether there is initial candidate route information whose historical starting port is the same as the starting port, and whose historical ending port is the same as the ending port. If there is initial candidate route information whose historical starting port is the same as the starting port, and whose historical ending port is the same as the ending port, then the initial candidate route information whose historical starting port is the same as the starting port, and whose historical ending port is the same as the ending port is determined as the candidate route information, that is, the historical route information whose historical route starting month, historical starting port and historical ending port all meet the user demand information is determined as the candidate route information.

[0034] Furthermore, if there is no initial candidate route information in which the historical starting port is the same as the starting port, and the historical ending port is the same as the ending port, the method also includes: acquiring port information, the port information including the port location; determining a port whose distance from the starting port is less than a first preset distance as a candidate starting port; determining a port whose distance from the ending port is less than a second preset distance as a candidate ending port; and determining the initial candidate route information in which the historical starting port is the same as the starting port or the candidate starting port, and the historical ending port is the same as the ending port or the candidate ending port as the candidate route information.

[0035] In this embodiment, if there is no initial candidate route information in which the historical starting port is the same as the starting port, and the historical ending port is the same as the ending port, the port information is obtained from the database or the staff, the port information includes the port location, the distance between each port and the starting port is calculated according to the port location, and the port whose distance from the starting port is less than the first preset distance is determined as the candidate starting port, the distance between each port and the ending port is calculated according to the port location, and the port whose distance from the ending port is less than the second preset distance is determined as the candidate ending port, wherein the first preset distance and the second preset distance are pre-set distances, which are not specifically limited here, and the initial candidate route information in which the historical starting port is the same as the starting port or the candidate starting port, and the historical ending port is the same as the ending port or the candidate ending port is determined as the candidate route information, that is, if the candidate route information cannot be matched according to the user demand information, it is recommended according to the historical route information corresponding to the ports near the starting port and the ending port.

[0036] Step S103: Score the candidate route information based on a scoring formula to obtain multiple scores.

[0037] Specifically, the candidate route information is scored based on a scoring formula to obtain multiple scores, including: determining scoring indicators based on historical route information, the scoring indicators include sailing mileage, sailing time, historical sea conditions, historical weather and total fuel consumption; determining historical sea condition impact factors based on historical sea conditions and sea condition scoring rules; determining historical weather impact factors based on historical weather and weather scoring rules; Obtain the weight coefficient corresponding to each scoring indicator; calculate the score of each candidate route information based on the weight coefficient, sailing mileage, sailing time, historical sea condition impact factor, historical meteorological impact factor, total fuel consumption and scoring formula; the scoring formula includes: Score=w1·(1 / D)+w2·(1 / T)+w3·(1 / S)+w4·(1 / W)+w5·(1 / F), where Score is the score, D is the sailing mileage, w1 is the weight coefficient corresponding to the sailing mileage, T is the sailing time, w2 is the weight coefficient corresponding to the sailing time, S is the historical sea condition impact factor, w3 is the weight coefficient corresponding to the historical sea condition, W is the historical meteorological impact factor, w4 is the weight coefficient corresponding to the historical meteorology, F is the total fuel consumption, and w5 is the weight coefficient corresponding to the total fuel consumption.

[0038] In this embodiment, the voyage mileage (in nautical miles), voyage time (in hours), historical sea conditions, historical weather, and total fuel consumption (in tons) are searched from the historical route information, and the sea condition scoring rules and weather scoring rules are searched from the database. The sea condition scoring rules are rules for scoring sea conditions, and the weather scoring rules are rules for scoring weather. The historical sea conditions are scored according to the sea condition scoring rules to obtain the historical sea condition impact factor, which is a value between 1 and 10. When the historical sea condition impact factor is 1, it indicates the best sea conditions, and when the historical sea condition impact factor is 10, it indicates the worst sea conditions. The historical weather is scored according to the weather scoring rules to obtain the historical weather impact factor, which is a value between 1 and 10. When the historical meteorological impact factor is 1, it means the weather is the best. When the historical meteorological impact factor is 10, it means the weather is the worst. The weight coefficient corresponding to each scoring indicator is obtained from the database, that is, the importance of each scoring indicator. The weight coefficient, sailing mileage, sailing time, historical sea condition impact factor, historical meteorological impact factor, and total fuel consumption are calculated through the scoring formula to obtain the score of each candidate route information. It is worth noting that when calculating the score, the reciprocal of each scoring indicator is taken, that is, the shorter the sailing mileage, the higher the score, the shorter the sailing time, the higher the score, the smaller the sea condition impact factor, the higher the score, the smaller the meteorological impact factor, the higher the score, and the lower the total fuel consumption, the higher the score. The sum of the weight coefficients corresponding to each scoring indicator is 1, that is, w1+w2+w3+w4+w5=1.

[0039] Step S104: Determine recommended route information based on the scores and candidate route information.

[0040] In this embodiment, when determining the recommended route information, the candidate route information with the highest score is determined as the recommended route information.

[0041] Specifically, after determining the recommended route information based on the score and the candidate route information, the method also includes: determining the sailing mileage, fuel consumption per 100 nautical miles and low-sulfur zone parameters based on the recommended route information; obtaining sea condition information and meteorological information based on the recommended route information and the route start date; determining the sea condition influencing factor based on the sea condition information and the sea condition scoring rules; determining the meteorological influencing factor based on the meteorological information and the meteorological scoring rules; and calculating the estimated fuel consumption based on the sailing mileage, fuel consumption per 100 nautical miles, low-sulfur zone parameters, sea condition influencing factor, meteorological influencing factor and the fuel consumption estimation formula.

[0042] In this embodiment, after recommending a route for the user, the fuel consumption of the route can also be estimated for the user, the voyage mileage, fuel consumption per 100 nautical miles and low-sulfur zone parameters are found from the recommended route information, the corresponding sea condition information and meteorological information on the recommended route on the start date of the route are obtained from the meteorological department, the sea condition information is scored according to the sea condition scoring rule to obtain the sea condition influence factor, the meteorological information is scored according to the meteorological scoring rule to obtain the meteorological influence factor, the voyage mileage, fuel consumption per 100 nautical miles, low-sulfur zone parameters, sea condition influence factor and meteorological influence factor are calculated through the fuel consumption estimation formula to obtain the estimated fuel consumption.

[0043] Furthermore, the fuel consumption estimation formula includes: FCE=(1+w·(W+S) / 2)·D·F·(1+Z·z), where FCE is the estimated fuel consumption, w is the sea condition and meteorological weight coefficient, which can be obtained from the database, W is the meteorological influence factor, S is the sea condition influence factor, D is the sailing mileage, F is the fuel consumption per 100 nautical miles, Z is the low-sulfur zone parameter, and z is the low-sulfur zone influence coefficient. The low-sulfur zone influence coefficient indicates the degree of influence on fuel consumption when passing through the low-sulfur zone, which can be obtained from the database.
