Abstract

The invention discloses an underwater wireless power and signal transmission system based on a dual-frequency point resonant cavity and relates to the technical fields of wireless power transmission and near-field magnetic communication. In order to solve the problems of low speed and poor quality of underwater wireless power transmission and underwater signal transmission communication at present, the system provided by the invention is characterized in that the signal is transmitted through a high-speed alternating current magnetic field; a digital signal is modulated into a high-frequency carrier signal in a 2FSK mode; the modulated signal is converted into a high-frequency alternating current magnetic field and then emitted by a power amplification and dual resonant cavity circuit structure; at the receiving end, an integrated transceiver resonant cavity generates resonance after receiving a high-frequency magnetic field; only signal transmission can be carried out due to a small coupling coefficient in a long-distance condition; the original signal at the transmitting end can be obtained after signal amplification and demodulation is carried out on small resonated current; energy transmission is carried out during signal transmission due since the coupling coefficient is large when a coil generates coupling resonance in a short distance. Therefore, the system is applicable to underwater wireless power and signal transmission.

Description

technical field [0001] The invention relates to the technical fields of wireless power transmission and near-field magnetic communication, in particular to an underwater wireless power transmission and signal transmission system. Background technique [0002] The power transmission between underwater equipment and between underwater equipment and surface equipment usually needs to surface the equipment, which undoubtedly limits the working time, working area and cost of underwater equipment, and traditional underwater equipment communication is generally The sonar system is used, and the transmission of sound waves in water will be affected by temperature, salt concentration, water flow, underwater noise, etc., the speed and quality of communication will be greatly affected, and it is easy to be interfered by humans, which will undoubtedly affect the underwater working equipment. normal work caused great difficulties. Contents of the invention [0003] The present inventi...
