The anchor is linked to a fixed column on the seabed. It can be assumed that the sea wave waveform is generated by the superposition of multiple sine waves. The floating body structure with the moving coil placed in it makes a simple harmonic reciprocating motion in the sea wave, causing relative motion between the moving coil and the magnet on the fixed track, resulting in a change in magnetic flux and generating an induced current. The current enters the storage battery through a wire. The power in the storage battery can provide electrical energy for the RF antenna and the transducer, realizing the function of the self-powered air-sea cross-domain communication gateway. Its component parts are as Figure 1 shown. Among them, the anchor and the track are connected by an anchor line, the track and the floating body structure are connected by a spring, the moving coil is directly embedded in the floating body structure, the storage battery is placed in the upper cabin of the floating body structure, the wire passes through the channel inside the floating body structure and is connected to the storage battery, and the storage battery is connected to the RF antenna above it and the underwater acoustic transducer below it through wires, and supplies power to the two through a voltage regulator.

[0036] It should be emphasized that in the process of realizing the self-powered air-sea cross-domain system networking, multiple factors need to be considered in signal processing:

[0037] Amplification and compression of signals: In order to amplify the signal coverage range and ensure the stability of signal connection, a digital signal amplifier needs to be installed to amplify the required signals.

[0038] Modulation and demodulation of signals: PSK and QAM modulation and demodulation technologies are selected to accurately realize the transmission of source coding through the channel and reduce redundancy.

[0039] Encryption and monitoring of signals: Different keys are used for different nodes to ensure the security of signal transmission; intercepted and inspected the received signals to avoid the communication system failure caused by source pollution.

[0040] Compared with related technologies, the self-powered air-sea cross-domain communication gateway system provided by the present invention is a key device for realizing air-sea cross-domain information exchange. The system combines multiple communication units to assemble a self-powered system, which can be anchored in the offshore area of our country. The signals are aggregated and processed through a signal conversion protocol, and different signals are transmitted by using multi-frequency channels; an encryption algorithm is added during transmission to ensure the security of the channel;
