AIS maritime search and rescue location indicator and location indicating method thereof

Abstract

The invention discloses an AIS maritime search and rescue location indicator and a location indicating method thereof. The AIS maritime search and rescue location indicator comprises a GPS radio frequency front-end, a GPS receiving module, an AIS radio frequency front-end, an AIS receiving module, an AIS transmitting module, a baseband information processing module and a power supply module, wherein the GPS receiving module is connected between the GPS radio frequency front-end and the baseband information processing module, the AIS receiving module and the AIS transmitting module are respectively connected between the AIS radio frequency front-end and the baseband information processing module, and the power supply module is also connected with the baseband information processing module. The search and rescue location indicator periodically inspects a residual electric quantity of a battery, and meanwhile dynamically adjusts a working condition of the GPS module according to signal strength of peripheral AIS equipment, so as to furthest improve working hours and transmitting efficiency of the search and rescue location indicator. The search and rescue location indicator also comprises a solar cell panel, and powers the battery via a photovoltaic effect, so that the working hours of the search and rescue location indicator are prolonged, and a search and rescue effect is improved.

Description

technical field [0001] The invention relates to the field of marine communication equipment, in particular to an AIS maritime search and rescue position indicating marker and a position indicating method thereof. 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. Maritime traffic accidents such as collision, grounding, grounding, sinking and other serious casualties still occur frequently. Life is priceless, and maritime search and rescue work plays a very important role. [0003] AIS system is an effective maritime collision avoidance, navigation and navigation aid safety system. Ac...
