Problems solved by technology

[0003] At present, there are many underwater communication devices for divers on the market, but due to the influence of turbid water quality, too long distance and floating solid objects, the main information transmission method of divers still stays at the stage of gesture communication
However, the complex environment and highly stressful underwater operations make it difficult for divers to recognize other people's gesture information, which will cause divers to be unable to convey information in time in an emergency, causing great danger and irreparable losses

Abstract

The invention discloses an underwater communication device and an underwater communication method based on ultrasonic transmission. The underwater communication device includes a sending system composed of a sending control module and an ultrasonic sending module, and also includes an ultrasonic receiving module and a receiving control module. The receiving system, the sending control module receives and recognizes external gesture signals, and sends the task instructions corresponding to the recognized gesture signals to the ultrasonic sending module, and the ultrasonic sending module sends corresponding ultrasonic signals according to the received task instructions; After the module receives the signal, it converts it into an electrical signal and sends it to the receiving control module. The receiving control module recognizes the received signal and sends the task instruction corresponding to the recognized signal to the display module at the receiving end to display the information. The underwater communication device based on ultrasonic transmission provided by the present invention is not affected by the underwater working environment, and the efficiency and accuracy of information transmission are high.

Description

technical field [0001] The invention relates to the research field of underwater communication equipment, in particular to a device for divers to transmit information underwater, and in particular to an underwater communication device and an underwater communication method based on ultrasonic transmission. Background technique [0002] As humans explore the ocean more deeply, underwater operations play an increasingly important role in many fields such as military affairs, archaeology, scientific research and environmental research. However, the dangers of underwater work are self-evident, such as water pressure, dark environment, aggressive creatures, difficulties in underwater communication, etc., especially underwater communication between divers. [0003] At present, there are many underwater communication devices for divers on the market, but due to the influence of turbid water quality, too long distance and floating solid objects, the main information transmission met...
