An underwater wearable command communication system and method

Abstract

The invention discloses an underwater wearable instruction communication system and method, and relates to an underwater acoustic communication technology. The communication system is provided with an instruction processing module, a display and control module, a signal processing module, a signal emitting module, a signal receiving module, a sensor processing module and a power supply and interface module. The communication method comprises an instruction communication step and an instruction display step. A frequency hopping multi-system frequency-shift keying technology is used; the underwater transmission of a gesture language instruction can be realized; and by combining the wearable performance and the display and warning functions, the reliability and the practicability of underwater communication of a diver are ensured.

Description

technical field [0001] The invention relates to underwater communication technology, in particular to an underwater wearable command communication system and method. Background technique [0002] The 21st century is the century of the ocean, and the resource development activities for the ocean are becoming more and more frequent. Since the underwater environment is unpredictable and often accompanied by great danger, it is necessary to equip divers with a communication system to report their location, underwater conditions, etc. in real time for collaborative operations. You can call for help in time to evacuate. Limited by the particularity of the underwater environment, such as the influence of water pressure, water flow and noise, the existing underwater communication system has many disadvantages, such as signal loss due to unstable communication, cumbersome operation and failure to make correct instructions in time (especially In the event of an emergency), the use o...

Problems solved by technology

Limited by the particularity of the underwater environment, such as the influence of water pressure, water flow and noise, the existing underwater communication system has many disadvantages, such as signal loss due to unstable communication, cumbersome operation and failure to make correct instructions in time (especially In the event of an emergency), the use of voice communication (inaudible), etc., which has brought serious safety hazards to divers and cannot adapt to the growing number of underwater activities (such as tourism, security, anti-terrorism, special operations, etc.) need
