Abstract

The invention relates to a method for deduplication and fusion of multi-source AIS data, which belongs to the field of ship information. The method includes: S1: each AIS receiving system deployed is serially numbered with a natural number ID, and a dictionary corresponding to the number ID of the AIS receiving system and the IP address of the AIS receiving system is established; S2: the ships to be collected by multiple AIS receiving systems The AIS signal is transmitted to the data processing center through the network in the form of original code or decoding, and the data processing center realizes deduplication and fusion processing of multi-source AIS data. The invention solves the redundant problem of AIS data collected by a multi-source AIS collection system without GPS, and reduces processing costs for data calculation, storage, transmission and the like.

Description

technical field [0001] The invention belongs to the field of ship information and relates to a method for deduplication and fusion of multi-source AIS data. Background technique [0002] AIS (Automatic Identification System) consists of shore-based facilities and ship-borne equipment. It is a digital navigation aid system and equipment based on wireless communication and digital information visualization. AIS equipment automatically and continuously sends important data related to ship navigation safety, such as ship identification information, position information, motion parameters and navigation status, to nearby ships and shore bases through the maritime VHF frequency band, so as to realize the identification and monitoring of ships in this area . On inland waterways, in order to realize the monitoring of ships in the entire waterway, it is necessary to deploy AIS receiving systems in multiple locations, so that it is possible to obtain the AIS signals of ships on the e...
