[0043] Next, in combination with the embodiments of the present invention, the technical solutions of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. 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.

[0044] The embodiment of the present application discloses a strong-fixed air-sea cross-domain communication gateway, including:

[0045] The gateway body; wherein, the gateway body includes: an intelligent anchoring control system for adjusting the tightness of the anchoring device.

[0046] A communication system for realizing information interaction between the gateway body and the outside world.

[0047] The power management system is connected to the intelligent anchoring control system and the communication system for supplying power to the gateway body.

[0048] The mechanical structure part includes an electronic cabin section, a floating body and an anchoring device. The bottom of the electronic cabin section is connected to the anchoring device for storing the functional modules of the intelligent anchoring control system, the communication system and the power management system. The floating body is sleeved in the middle of the electronic cabin section for providing buoyancy support for the entire gateway. One end of the anchoring device is fixed in the seabed soil and the other end is connected to the gateway body for anchoring the gateway body.

[0049] In this application, the strong-fixed anchoring device enables the air-sea cross-domain communication gateway to be firmly installed at a predetermined position, ensuring a stable communication connection of the air-sea cross-domain communication gateway under harsh environmental conditions (such as strong winds, big waves, strong airflows, etc.). This stability is crucial for air-sea cross-domain communication because any slight movement or deviation may affect the transmission quality and stability of the communication signal. The strong-fixed anchoring device in this application can reduce the mechanical damage and fatigue of the air-sea cross-domain communication gateway caused by external factors such as vibration and shaking, contribute to extending the service life of the air-sea cross-domain communication gateway, reduce the frequency of maintenance and replacement, and lower the overall operation cost.

[0050] In another embodiment of this application, the anchoring device includes: an anchor body, an anchor crown, anchor arms, anchor claws, an anchor chain and an anchor shackle. The anchor crown is connected to the bottom of the anchor body for firmly fixing connection with the anchor chain and releasing the anchoring. It can be understood that the anchor crown uses a tightening structure for firmly fixing connection with the anchor chain and releasing the anchoring.

[0051] One end of the anchor arm is rotatably connected to the anchor body and the other end is connected to the anchor claw. The anchor claw is used to generate a gripping force in the seabed soil to fix the anchor body and the connected structure. It can be understood that when the anchor body is thrown into the seabed, the anchor claw will bite into the soil and use the resistance of the soil to resist the pulling force from other structures.

[0052] The anchor shackle is connected to the top of the anchor body. One end of the anchor chain is connected to the anchor shackle and the other end is connected to the electronic cabin section. The anchor chain, as a tension member, is used for the connection between the anchoring part and the air-sea cross-domain communication gateway. The intelligent anchoring control system is used to adjust the tightness of the anchor chain. It can be understood that one end of the anchor chain is connected to the gateway and the other end is composed of a cone shell with a conical groove and a cone with a corresponding taper. When the anchor chain is rotated, the cone moves into the expanding shell and makes the expanding shell open and fixed in the anchor crown.

[0053] In this embodiment, the intelligent anchoring control system includes: a marine environment monitoring module, a first main control unit module, and a motor control module.

[0054] Specifically, the marine environment monitoring module includes: a flow velocity sensor for collecting the water flow velocity; an inertial sensor for collecting the inertia magnitude; a wave sensor for collecting wave information; and a force measuring sensor for collecting the force condition of the gateway body. The motor control module transmits the collected water flow velocity, inertia magnitude, wave information, and the force condition of the gateway body to the first main control unit for analysis and processing to obtain the attitude adjustment instruction of the gateway body, and adjusts the tightness of the anchor chain according to mechanics.

[0055] In another embodiment of the present application, the communication system includes a communication device module and a second main control unit module. The second main control unit module realizes information interaction with the outside world through the communication device module.

[0056] Specifically, the communication device module includes a Beidou communication terminal, a mobile communication terminal, a data transmission radio communication terminal, and an underwater acoustic communication terminal dry end.

[0057] In this embodiment, a strong fixed type air-sea cross-domain communication gateway further includes: an underwater acoustic communication terminal wet end for realizing the conversion between electrical signals and acoustic signals; the underwater acoustic communication terminal wet end is located in a seawater area at a specific depth, and the underwater acoustic communication terminal wet end communicates with the underwater acoustic communication terminal dry end through a cable.

[0058] In this embodiment, the communication forms of the underwater acoustic communication terminal dry end include: a spread spectrum mode and an orthogonal frequency division multiplexing (OFDM) mode. Both the spread spectrum mode and the orthogonal frequency division multiplexing (OFDM) mode realize the corresponding signal modulation through ARM and DSP.

[0059] In another embodiment of the present application, the power management system includes: a battery pack, a voltage conversion device, an STM32 single-chip microcomputer, a relay, a capacitor, a rectifier, and a backup battery pack. The power management system is mainly responsible for outputting the electric energy of the battery pack to provide power support for the normal operation of other systems, and the backup battery pack can be enabled for power supply when the energy of the battery module is exhausted.

[0060] 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. The battery pack can stably output 3.3V, 5V, 12V, and 24V voltages through the voltage conversion device.

[0061] The STM32 single-chip microcomputer is used to receive the collected power parameter information and perform processing, judgment, and decision-making. The relay is used to achieve circuit switching and circuit protection. It can be understood that the programming and burning program code can download the power supply control instruction information in the STM32 single-chip microcomputer, orderly control the power supply situation through the relay, and at the same time, the battery pack power information can be obtained.

[0062] This application utilizes a rigid structure with special materials, combined with a variety of anchoring methods. The strong fixation of the rigid structure stabilizes the entire device, ensures the stability of the posture, and supports reliable cross-domain communication.

[0063] Referring to Figure 2 , the working process of a strongly fixed air-sea cross-domain communication gateway in an embodiment of this application is specifically as follows:

[0064] The intelligent anchoring control system collects the water flow velocity, inertia magnitude, wave information, and the force condition of the gateway body through a flow velocity sensor, an inertial sensor, a wave sensor, and a force sensor, and transmits the collected information to the first main control unit for analysis and processing to obtain the gateway body attitude adjustment instruction. According to mechanics, the tightness of the anchor chain is adjusted. If the gateway body deviates in a certain direction, the motors and steering gears in that direction start to loosen the anchor chain, and the motors and steering gears in the other direction start to tighten the anchor chain, so as to achieve the effect of balancing the communication gateway and maintain the stability of the gateway body.

[0065] The application scenario of a strongly fixed air-sea cross-domain communication gateway in an embodiment of this application is as Figure 3 shown:

[0066] 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 the strongly fixed cross-domain communication gateway in shallow water, the anchor claw bites into the soil, the anchor crown is connected to the anchor chain through a tensioning structure, and the other end of the anchor chain is connected to the gateway body. At this time, the intelligent anchoring control system works, and the ocean environment monitoring module collects information and transmits it to the main control unit for analysis and processing to obtain the gateway body attitude adjustment instruction. The motor control module receives the instruction and starts to work, adjusting the tightness of the anchor chain according to mechanics. If the gateway body deviates in a certain direction, the motors and steering gears in that direction start to loosen the anchor chain, and the motors and steering gears in the other direction start to tighten the anchor chain, realizing the stability and balance of the cross-domain communication gateway, ensuring the stability of the communication signal, and realizing the information interaction between the cross-domain communication gateway and the shore-based computer and the information interaction with the underwater unmanned node to complete the communication task.

[0067] The embodiments described above are only descriptions of the preferred embodiments of the present invention, and do not limit the scope of the present invention. Without departing from the spirit of the design of the present invention, various deformations and improvements made by those of ordinary skill in the art to the technical solutions of the present invention shall fall within the protection scope determined by the claims of the present invention.
