Embodiment Construction

[0035] see figure 1 , in the embodiment of the present invention, a kind of AIS single channel receiver of automatic frequency hopping, comprises GPS radio frequency front-end (1), GPS receiving module (2), AIS radio frequency front-end (3), AIS receiving module (4) and baseband information Processing module (5).

[0036] The GPS radio frequency front end (1) is externally connected to a GPS antenna, receives radio frequency signals, and sends the processed radio frequency signals to the GPS receiving module (2) for further processing. The GPS receiving module (2) is connected with the GPS radio frequency front end (1), and the GPS receiving module (2) carries out down-conversion, signal amplification and analog-to-digital conversion to the radio frequency signal sent by the GPS radio frequency front end (1), and sends the signal to into the baseband information processing module (5) for digital processing.

[0037] The AIS radio frequency front end (3) is externally connect...

Abstract

The invention discloses an automatic frequency hopping AIS single-channel receiver, which comprises a GPS radio frequency front end, a GPS receiving module, an AIS radio frequency front end, an AIS receiving module and a baseband information processing module, wherein the GPS radio frequency front end is connected to the GPS receiving module; the GPS receiving module is connected to the baseband information processing module; the AIS radio frequency front end is connected to the AIS receiving module; and the AIS receiving module is connected to the baseband information processing module. The automatic frequency hopping AIS single-channel receiver detects the congestion situation of two channels of an AIS in real time, so that the receiver is set to work in a fixed frequency hopping mode ora dynamic frequency hopping mode. When the receiver is in the dynamic frequency hopping mode, the random characteristics of slot conflicts of the two channels are detected in real time, the preferredslot conflicts are less and the AIS slot utilizes the higher frequency point to work. Through application of the automatic frequency hopping AIS single-channel receiver, the lock time of peripheral AIS transmitters can be remarkably reduced and the number of received effective information is increased.

Description

technical field [0001] The invention relates to the technical field of AIS (Automatic Identification System) for ships, in particular to an AIS single-channel receiver with automatic frequency hopping. Background technique [0002] In recent years, with the rapid development of ship technology and the rise of marine economy, the status of maritime transportation has become increasingly prominent, and the world shipping market has been expanded and developed unprecedentedly. The rapid development of the world's shipping industry has brought huge economic benefits, but it has also made the maritime traffic situation more and more complicated. [0003] AIS system is an effective maritime collision avoidance, navigation and navigation aid safety system. According to the mandatory requirements of the International Maritime Organization (IMO), all international voyage ships of more than 300 tons and non-international voyage ships of more than 500 tons have been installed with AIS...
