Problems solved by technology

Sonar technology is currently the most mature underwater communication technology, but the propagation speed of sound waves in water is low, and the scattering of sound waves in water, the loss of transmission and the interference of echoes are also relatively serious.
Therefore, the data transmission rate using sonar for communication is slow, and the transmission of large data files such as pictures, videos, and audios cannot be completed.
The wired and cable communication method requires complex wiring, which limits the range of communication equipment such as aircraft

Embodiment 1

[0039] This embodiment provides an underwater communication method, which is applied to water area vehicles. The water vehicle is equipped with an acoustic detector and a laser communication module with an angle adjustment mechanism. Such as figure 1 As shown, the method includes the following steps:

[0040] In step S101, the location of the communication object is determined through an acoustic detector.

[0041] Wherein, the acoustic detector may be a sonar or an ultrasonic sensor or the like. The sound wave signal emitted by the communication object is received by the acoustic detector, and the orientation of the communication object relative to the water area vehicle can be determined according to the direction of the sound wave signal.

[0042] It can be understood that, in addition to receiving the acoustic signal emitted by the communication object, the acoustic detector is also used for emitting the acoustic signal. Therefore, before or after step S101, the method...

Description

technical field [0001] The present invention relates to the technical field of underwater communication, in particular, to an underwater communication method, device, equipment and system. Background technique [0002] Existing underwater communication technologies mainly include sonar technology and wired cable communication technology. Sonar technology is currently the most mature underwater communication technology, but the propagation speed of sound waves in water is low, and the scattering of sound waves in water, the loss of transmission and the interference of echoes are also relatively serious. Therefore, the data transmission rate using sonar for communication is slow, and it is impossible to complete the transmission of large data files such as pictures, videos, and audios. However, the wire and cable communication method requires complicated wiring, which limits the range of movement of communication equipment such as aircraft. Contents of the invention [000...
