Automatic recognition monitoring system of marine vehicle

Abstract

The invention discloses an automatic identification and monitoring system for ships, which belongs to the technical field of ship identification and monitoring. Hardware components comprise a ship terminal AIS module, a communication network and a host computer platform, wherein the ship terminal AIS module is connected with the host computer platform through the communication network in a wireless way; the ship terminal AIS module consists of a common interface for ship navigation devices, an information processor, an information monitor, a VHF transceiver, a GPS module and a communication module, which are connected electrically; the communication network comprises SOTDMA/VHF and GPRS/CDMA public network, wherein the SOTDMA/VHF and the GPRS/CDMA public network are electrically connected with a ship terminal and the host computer platform respectively; and the host computer platform is positioned in a base station center and consists of a data communication layer, a ship management layer and a user interface management layer. The automatic identification of ships is realized through direct communication between ships or the ship basic information transfer of a base station. The system overcomes the drawbacks of the prior ship navigation device in terms of communication distance and reliability, enlarges the communication range of the ships, ensures the reliability of communication and improves the safety of the ships.

Description

technical field [0001] The invention relates to a ship automatic identification and monitoring system, which belongs to the technical field of ship identification and monitoring. Background technique [0002] The existing marine radar has the function of collision avoidance, but its work is often affected by weather and sea conditions. In narrow waterways, waters with high density of ships or encountering bad weather, the radar is powerless; Identification system (Automatic Identification System, referred to as AIS). Some existing AIS are based on very high frequency (VHF) communication means and adopt self-organizing time division multiple access (SOTDMA) communication mode, but it is difficult to realize automatic identification in narrow waterways. Another kind of AIS works based on the public network, application number: 200510047171.0 publication (announcement) number: CN1737877A: a kind of ship automatic identification system based on public network GPRS / CDMA / 3G, util...
