Description

Ship detention risk prediction method and system, electronic equipment and storage medium Technical Field The invention relates to the technical field of ships, in particular to a ship detention risk prediction method and system, electronic equipment and storage medium. Background Port national supervision is translated from English Port State Control (PSC), or called Port national control, and is specially implemented by port authorities around the world on foreign ships reaching the port to ensure the safety of the ships and personnel and prevent marine pollution, and is specially and specifically checked by shipmen and ship technical conditions, wherein the influence on the operation of the ships and shipcompanies is most serious due to 'detention' in the processing measures of the check. However, in the related art, the risk of the ship staying in a specific port country cannot be predicted in time. Disclosure of Invention The present invention aims to solve at least one of the technical problems existing in the prior art or related art. To this end, a first aspect of the invention proposes a method of predicting risk of ship retention. A second aspect of the invention proposes a prediction system for risk of ship retention. A third aspect of the invention proposes an electronic device. A fourth aspect of the present invention proposes a storage medium. In view of this, according to a first aspect of the present invention, there is provided a ship stagnation risk prediction method comprising determining a destination port and an expected port time of a ship, determining a port national supervision organization to which the destination port belongs and first data according to the destination port, wherein the first data corresponds to the port national supervision organization, acquiring profile data of the ship, determining a historical port national supervision and inspection record of the ship according to the profile data, wherein the historical port national supervision and inspection record corresponds to the port national supervision organization, and predicting the ship stagnation risk according to the expected port time, the historical port national supervision and inspection record, the port national supervision organization and the first data. The ship detention risk prediction method mainly comprises the steps of firstly determining a destination port of a ship and predicting arrival time, wherein the destination port refers to a port where the ship is to be moored next. The port national supervision organization to which the destination port belongs is then determined according to the destination port of the ship, and it is understood that the port national supervision organizations to which the ports of different countries and regions belong are different, and the port national supervision rules used by the different port national supervision organizations are also different. Therefore, after obtaining the information of the destination port, the port national supervision organization to which the destination port belongs can be determined according to the region where the destination port is located. Further, the port national supervision organization may issue all items to be inspected during port national supervision inspection, and the port national supervision organization may also issue Annual concentrated inspection (Concentrated Inspection Campaign, CIC) items and Annual reports (Annual Report) periodically, in which high frequency defect items and retention items may be published and ranked. Therefore, after the port national supervision organization of the destination port is determined, the first data corresponding to the port national supervision organization may be determined, and the first data may be an inspection period of the port national supervision organization, all items to be inspected issued by the port national supervision organization, and the issued high-frequency defect items and the published hold-up items. The profile data of the vessel is then obtained, wherein the profile data may be obtained from a Rough class society. The laugh classification society is an IMO number issuing, managing and verifying department designated by the international maritime organization (International Maritime Organization, IMO), and the authority and completeness of the data are not accessible. The archive data includes detailed technical parameters of ships and equipment, construction conditions, insurance associations, income level and PSC (Port State Control, port national supervision) inspection records, owners, operators, buying and selling conditions and other authoritative archive data. After the archive data of the ship is obtained, determining a historical port national supervision and inspection record of the ship according to the archive data of the ship, namely, the inspection record obtained after port national supervision and inspection is carried out before the s
