Abstract

Provided is a piece of AIS (automatic identification system) equipment capable of providing a wireless data interface. A wireless WIFI / Bluetooth module, a 3G / GPRS module and a communication processing unit are added on the basis of a piece of traditional AIS equipment. The AIS data interface is connected with all wireless communication modules in a bridging manner. A wireless WIFI / Bluetooth data interface and 3G / GPRS data uploading are provided.

Description

technical field [0001] The invention relates to an AIS (Automatic Identification System for Ships) device capable of providing a wireless data interface, in particular to an AIS device capable of providing a wireless WIFI / Bluetooth data interface and 3G / GPRS data upload. Background technique [0002] AIS is an effective maritime safety system for collision avoidance, navigation, and navigation assistance. The maritime departments of various countries are stepping up promotion and even mandatory installation. At present, general-purpose AIS equipment is composed of VHF antenna, GPS antenna, AIS processing unit, and wired data interface (usually a serial port). The AIS device locates the coordinates of the own ship through the GPS antenna, receives the position reports and static information of other AIS devices within the surrounding signal coverage through the VHF antenna, and sends the dynamic and static data of the device to the surroundings according to the specified time...
