Marine emergency rescue terminal based on underwater acoustic system and implementation method thereof

Abstract

The invention provides a marine emergency rescue terminal based on an underwater acoustic system. The marine emergency rescue terminal comprises an outer shell, a microprocessor, an information receiving and transmitting module, a positioning switching module, an alarm module, a power management module, a display module and an interaction module, the positioning switching module comprises an overwater positioning module and an underwater positioning module, the underwater positioning module comprises an underwater positioning state detection module, the underwater positioning state detection module comprises an energy exchanger, and under a set trigger water pressure value, the energy exchanger converts water pressure into electric energy and converts the electric energy into ultrasonic waves. A positioning switching module is arranged, so that the terminal can be freely switched between water and water in a positioning manner, ultrasonic waves are emitted by utilizing an energy conversion principle of an energy exchanger for positioning and alarming, rescue of a rescue ship sinking into the seabed in danger is facilitated, and the problem that electronic waves cannot be spread in water is solved; the information receiving and transmitting module of the three-in-one antenna module is designed, multiple positioning communication modes are provided, and the limitation of an independent antenna module is solved.

Description

technical field [0001] The invention relates to the technical field of marine rescue equipment, in particular to a marine emergency rescue terminal based on an underwater acoustic system and an implementation method thereof. Background technique [0002] With the continuous development of modern navigation technology, ships are developing towards large-scale, high-speed, and specialization, and the manning on board is developing toward multi-nationality. However, due to the relatively harsh sailing environment of ships, there are still many ships and crew members who are in distress during the voyage. . After the ship is in distress, due to factors such as the on-site weather environment and limited rescue equipment, the on-site rescue situation is more complicated, which makes the rescue work face many unexpected difficulties. After the scene of the distress, but the ship in distress or the person in distress cannot be found, which increases the rescue difficulty of the re...

Problems solved by technology

Since there are no base stations at sea, information transmission cannot be performed

At present, the GPS module can only be used as an auxiliary positioning function for other devices.

[0006] Moreover, the above-mentioned AIS system, Beidou RDSS / RNSS terminal products, and GPS equipment are all transmitted through electronic waves, except for the disadvantages of their separate use, and electronic waves cannot propagate in sea water. Therefore, rescue ships often appear When arriving at the scene of distress, no trace of the ship or persons in distress can be found. For example, a container full of goods sinks to the bottom of the sea, but no trace of the container can be found, which will cause great losses
