Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0036] To solve the problem that the antenna of the air-sea cross-domain communication gateway is offset due to the unstable marine environment, this application proposes an air-sea cross-domain communication gateway with position adaptive correction and its working method to ensure the stability of the antenna of the air-sea cross-domain communication gateway, thereby ensuring the communication quality.

[0037] Referring to Figure 1 and Figure 2 An embodiment of this application provides an air-sea cross-domain communication gateway with position adaptive correction, including: an adaptive correction module, a communication module, a power management module, an electronic cabin section, and a floating body.

[0038] Among them, the adaptive correction module is used to receive the position information of the gateway antenna, calculate the angles and positions that need to be adjusted, and adjust the position and angle of the gateway antenna.

[0039] The communication module is connected to the adaptive correction module and is used to realize the information interaction between the gateway and the outside world.

[0040] The power management module is connected to the adaptive correction module and the communication module and is used to provide power for the entire gateway.

[0041] The electronic cabin section is used to store the adaptive correction module, the communication module, and the power management module.

[0042] The floating body is sleeved outside the electronic cabin section and is used to provide buoyancy support for the entire gateway.

[0043] Through the mutual cooperation among the adaptive correction module, the communication module, and the power management module, the present invention realizes the real-time monitoring and precise control of the gateway attitude.

[0044] In this embodiment, the adaptive correction module includes a sensor, a controller, and an actuator.

[0045] The sensor includes an angle sensor and a position sensor, which are responsible for receiving the position of the gateway antenna and the angle information between the gateway antenna and the horizontal line.

[0046] According to the feedback signal of the sensor, the controller calculates the positions and angles that need to be adjusted through the built-in instruction table, and then drives the actuator to make corresponding adjustments.

[0047] The actuator is used to adjust the position and angle of the gateway antenna to ensure the stability of the communication signal and the communication quality. The actuator includes a motor and a transmission mechanism, and the transmission mechanism is used to convert the rotational motion of the motor into the motion required to adjust the position and angle of the gateway antenna.

[0048] It can be understood that in this application, the position and angle information of the gateway antenna is received by the sensor, the information is processed by the controller, and the actuator works to adjust the position and angle of the air-sea cross-domain communication gateway antenna, realizing stable control of the air-sea cross-domain communication gateway antenna, ensuring that the antenna always points to a fixed direction, and ensuring the stability of the communication signal and the communication quality.

[0049] In this embodiment, the communication module includes a communication device and a main control unit. The communication device and the main control unit are connected by wire, and the main control unit realizes information interaction with the outside world through the communication device. The communication device includes a Beidou communication terminal, a mobile communication terminal, a data transmission radio communication terminal, and a dry end of an underwater acoustic communication terminal.

[0050] Preferably, the communication forms of the dry end of the underwater acoustic communication terminal include: spread spectrum mode and orthogonal frequency division multiplexing (OFDM) mode. Both the spread spectrum mode and the orthogonal frequency division multiplexing (OFDM) mode realize corresponding signal modulation through ARM and DSP.

[0051] This embodiment of an air-sea cross-domain communication gateway with position self-adaptive correction further includes: a wet end of an underwater acoustic communication terminal, which is used to realize the conversion between electrical signals and acoustic signals; the wet end of the underwater acoustic communication terminal is located in a seawater area at a specific depth, and the dry end of the underwater acoustic communication terminal is located inside the cross-domain communication gateway. The wet end of the underwater acoustic communication terminal communicates with the dry end of the underwater acoustic communication terminal through a watertight cable.

[0052] In this embodiment, the power management module includes: a battery pack, a voltage conversion device, a rectifier, a capacitor, a photovoltaic controller, an STM32 single-chip microcomputer, a relay, and a backup battery pack.

[0053] Among them, both the battery pack and the backup battery pack are used to provide electrical energy for the entire gateway. It can be understood that the electrical energy output of the battery pack provides power support for the normal operation of other functional modules. Especially when the energy of the battery pack is exhausted, the backup battery pack can be enabled for power supply.

[0054] Preferably, the voltage conversion device includes a 3.3V voltage conversion board, a 5V voltage conversion board, a 12V voltage conversion board, and a 24V voltage conversion board.

At the same time, the battery pack power information can be obtained.

[0056] Refer to Figure 3, an embodiment of the present application provides a working method for a position self - adaptive correction air - sea cross - domain communication gateway, which is as follows:

[0057] When the air - sea cross - domain communication gateway fluctuates due to sea waves, the self - adaptive correction module starts to work. It receives the position information of the gateway antenna and the angle information between the antenna and the horizontal line and the vertical line through the angle sensor and the position sensor, and then transmits them to the controller. According to the feedback signal of the sensor, the controller calculates the position and angle that need to be adjusted through the built - in instruction table, and then drives the actuator to make corresponding adjustments. When the actuator works, the motor starts, and the transmission mechanism converts the rotational motion of the motor into the motion form required to adjust the position and angle of the antenna, thereby driving the gateway antenna to perform rotational, pitching and other motions, adjusting the roll axis, pitch axis and yaw axis, so as to ensure the stability of the position and angle of the antenna, ensure the stability of the communication signal, and guarantee the communication quality.

[0058] An embodiment of the present application provides an application scenario of a position self - adaptive correction air - sea cross - domain communication gateway as Figure 4 shown:

[0059] Among them, the cross - domain communication gateway serves as the first communication terminal, the underwater device serves as the second communication terminal, and the shore - based computer platform. After installing a position self - adaptive correction air - sea cross - domain communication gateway on the ocean, start the gateway. When encountering sea waves, the gateway fluctuates back and forth and rises and falls. At this time, the sensor receives the position information and angle information of the gateway antenna and transmits them to the controller. According to the feedback signal of the sensor, the controller calculates the position and angle that need to be adjusted through the built - in instruction table, the motor and the transmission mechanism start, adjust the position and angle of the gateway antenna, and maintain the stability of the gateway antenna, ensuring the stability of the communication signal and the communication quality.

[0060] Through high - precision sensors and controllers, the present invention can realize real - time monitoring and precise control of the gateway attitude. In the marine environment, due to the influence of natural factors such as wind and waves, the attitude of the gateway may change, resulting in the deviation of the antenna position and angle. Through the method in the present invention, the position and angle of the gateway antenna can be adjusted in time, enabling the antenna to better align with the communication target, ensuring the stability of the communication signal and the communication quality. The air - sea cross - domain communication gateway of the present invention also has an anti - jitter function, which can effectively reduce the impact of jitter caused by wind and waves on the communication signal, enabling the gateway to maintain a stable communication state in the marine environment, and improving the reliability and stability of communication. Through the air - sea cross - domain communication gateway of the present application, users can achieve more efficient information exchange and resource sharing, promoting cross - domain cooperation and development.
