Mobile electronic fence system based on virtual AIS technology

Abstract

The invention discloses a mobile electronic fence system based on a virtual AIS technology. The system comprises an AIS station installed on a ship and used for receiving an AIS message, a GNSS moduleused for determining the position of a mobile dangerous area, an AIS sending module used for broadcasting an AIS virtual navigation mark and an information processor used for calculating the real-time position of the broadcasted AIS virtual navigation mark. The GNSS module is installed in the mobile dangerous area, the information processor is connected with the GNSS module and acquires a positioning location in real time, and after the information processor calculates the AIS virtual navigation mark position, the AIS message which can be received by the AIS station is broadcasted through theAIS sending module.

Description

technical field [0001] The invention relates to the technical field of navigation aids, in particular to a mobile electronic fence system based on virtual AIS technology. Background technique [0002] In the prior art, the electronic fence system is used for the safety of ship navigation, but most of the current electronic fences are fixed to indicate the warning area. With the development of the marine economy, marine power breeding cages have appeared. Aquaculture cages need to be moved. Ships hitting Shanghai dynamic aquaculture cages will not only cause economic losses for farmers, but also pose huge safety problems. In addition, some important ships need to be protected accordingly. These ships can also be If it is mobile, it will cause huge economic losses once it hits it. The fixed electronic fence in the prior art cannot meet the use requirements of protecting offshore power breeding cages and important ships at sea. Contents of the invention [0003] In order to ...
