Monitoring method for ship passing through special area

Abstract

The invention provides a monitoring method for a ship passing through a special area, and the method can carry out the cleaning, conversion and correlation storage of massive ships and ship AIS data, and draws a more precise ship track; the method also includes analyzing AIS data, and providing more accurate ship state judgment; carrying out electronic processing and division on the global special area; providing risk early warning for the ship to pass through a special area in real time, and solving the pain point of post declaration at present. According to the invention, global ship mass AIS data is cleaned and sorted, electronic processing is carried out on a shipping global special area, and timely and accurate ship special area passing monitoring is provided. In addition, a special area is reduced through circumscribed rectangle processing, and the requirement for computing resources of traversal data judgment is lowered.

Description

technical field [0001] The invention relates to the technical field of shipping information, in particular to a monitoring method for ships passing through special areas. Background technique [0002] In order to ensure the safe passage of ships in the waterway, it is necessary to track and monitor the ships in the water area to actively avoid safety accidents. There are many special areas defined by the shipping business, including but not limited to special warfare areas, pirate areas, low-sulfur areas, ice areas, sanction areas, etc. Ship tracking in special areas is of great significance to ensure the safety of ships, crew and cargo, and reduce the losses of shipowners and cargo owners. At present, the mainstream ship tracking methods are as follows: first, the method mainly focuses on port and coastal tracking. In this method, the ship base installs the transmitter, the shore base installs the receiver device, and realizes the dynamic data transmission of the ship thro...

Problems solved by technology

At present, the mainstream ship tracking methods are as follows: first, the method mainly focuses on port and coastal tracking. In this method, the ship base is installed with a transmitter, the shore base is equipped with a receiver, and the ship's dynamic data transmission is realized through a CDMA network. However, this method is far away from the coastline. Insufficient regional tracking analysis for

The second is the global satellite positioning system (GPS): its function is positioning, and it can serve time, measure the ship's track direction, speed, wind current pressure difference, and carry out navigation. timeliness and accuracy, and are primarily used for navigation

According to Clarkson's latest report, by February 2021, the number of ships in the global fleet (above 100GT) will exceed 100,000, reaching 100,001. If the above-mentioned ships are to be tracked globally, it will consume huge computing resources
