Dual-mode positioning beacon applicable to ocean comprehensive observation buoy and method

Abstract

The invention relates to the field of ocean observation, in particular to a dual-mode positioning beacon applicable to an ocean comprehensive observation buoy and a method. The dual-mode positioning beacon comprises a case, a positioning communication module, a control module and a power supply module, wherein the positioning communication module, the control module and the power supply module arearranged in the case; the positioning communication module comprises a GPS module and a Beidou module; the upper end of the control module is respectively connected with the GPS module and the Beidoumodule through different circuits; the lower end of the control module is connected with the power supply module; a watertight port is formed in the case; and the control module is connected with thewatertight port through a circuit. Besides the use of the conventional GPS for positioning, the message communication and positioning functions of the independently researched and developed Beidou satellite in China are also used; and meanwhile, the problem of GPS signal blind areas and the problem of poor transmission security of an iridium satellite are solved.

Description

technical field [0001] The invention relates to the field of ocean observation, in particular to a dual-mode positioning beacon and method suitable for ocean comprehensive observation buoys. Background technique [0002] The comprehensive marine observation buoy system is currently the main platform for long-term continuous online monitoring of the ocean in my country. Its main features are long working hours and unattended operation, especially the ability to obtain ocean observation data in extremely bad weather. way incomparable. The safe on-site operation of buoys is the basis for the stable acquisition of ocean observation data. However, during the on-site operation of the comprehensive ocean observation buoy system, sometimes due to the influence of typhoons, cold waves, and fishing boat trawls, the buoy system will run off the mark and shift. The real-time tracking of position information when shifting and running is very important, because the instruments and equipme...
