and an identification module 1006 for identifying the operation behavior of the tanker based on the image data.
The present invention provides an operation behavior recognition system 100 of a tanker, wherein the operation behavior recognition system 100 of the tanker comprises: extraction module 1002, acquisition module 1004, and identification module 1006. After acquiring the AIS data of the oil supply ship in real time, the extraction module 1002 performs big data analysis on the AIS data by using the GIS technology after acquiring the AIS data, and extracts data type information in the AIS data, that is, landing type information and landing type information of the ship. The data type information, i.e., the landing event and the landing event, obtained by performing big data analysis processing on the AIS data is very accurate. After the data type information is extracted, the acquiring module 1004 acquires the image data of the oil supply assembly corresponding to the data type information in the oil supply ship, and the identifying module 1006 identifies the image data through the AI intelligence, so as to determine the current operation behavior of the oil supply ship. According to the invention, through mutual complementation of AIS data and video AI intelligent identification data, AI calculation force and mobile network flow are greatly saved, and the identification accuracy of the oil supply ship operation behavior is greatly improved.

When the component type is the first component type, but the oil supply component is not in an operating state, it is indicated that the oil supply ship has stopped the oil supply operation.
In some embodiments, optionally, the identification module 1006 is specifically configured to determine that the oil supply vessel is performing the oil filling operation based on the component type being the second component type and the oil supply component being in an operating state; and determining that the oil supply ship stops the oil filling work based on the fact that the component type is the second component type and the oil supply component is in an unoperated state.
