Problems solved by technology
[0004] However, underwater audio communication based on optical communication also has certain problems. Due to the complexity of the underwater environment, divers cannot distinguish the direction of the sound source by listening to the sound underwater, that is, the sense of direction underwater is not strong.

The invention discloses an underwater audio-optical communication system and method with auxiliary function of sense of direction. The underwater audio-optic communication system includes an optical signal transmitting system and an optical signal receiving system. The optical signal transmitting system includes an audio input device and a transmitting circuit module. and a light-emitting device; the optical signal receiving system includes a light-receiving module, a receiving circuit module and an audio output device, the light-receiving module includes a first light-receiving device and a second light-receiving device, and the first light-receiving device and the second light-receiving device are used for Receive light signals from different directions, the audio output device includes a first sound channel and a second sound channel, and the receiving circuit module is used to convert the light signal received by the first light receiving device or the second light receiver into The electrical signal played in the first or second channel. In the present invention, the right ear channel of the receiving system is connected to the signal corresponding to the right photodiode, that is, the direction of the signal can be distinguished through the sound of the left and right channels, and the direction sense of underwater communication is enhanced.
Description
technical field [0001] The invention relates to an underwater audio optical communication system with a directional sense auxiliary function, belonging to the technical field of communication and information. Background technique [0002] The traditional underwater acoustic communication technology has many shortcomings such as low communication rate, high delay, narrow bandwidth, large equipment size, high power consumption and high cost, and cannot effectively improve the communication transmission rate. Realize long-distance high-speed communication underwater. With the further exploration and development of marine resources by human beings, underwater high-speed, convenient, real-time and stable communication is an urgent problem to be solved. [0003] The application and development of visible light communication technology provides a new technical solution for solving this communication problem. Since the underwater visible light communication technology uses visible...
