Description

technical field [0001] The invention relates to a deep-sea non-contact signal transmission device, in particular to a deep-sea non-contact signal transmission device based on LED optical communication. Background technique [0002] Autonomous underwater robot (AUV), remotely controlled underwater robot (ROV) and manned submersible (DSV) are the main delivery equipment for deep sea scientific investigation and resource exploration. test tool. In order to ensure the absolute safety of ROVs, AUVs and DSVs, the carrying equipment must be successfully separated from the scientific research tools in an emergency. Therefore, the signal transmission between the carrier equipment and the scientific research tool is realized by a non-contact signal transmission device. It should be emphasized that due to the special environment of the deep sea, the use of a single communication medium cannot fully guarantee the success of the communication, and a highly reliable wireless signal tran...
