[0001] This invention relates to the fields of underwater communication and fiber optic sensing technology, specifically to a deep-sea agile communication network and real-time detection system. Background Technology

[0002] With my country's increasing emphasis on the ocean, the number of underwater scientific research, civilian, and military equipment deployed has grown rapidly in recent years. However, various equipment used in the deep sea, whether fixed or autonomously manned / unmanned, faces challenges in achieving real-time communication, making real-time data transmission from deep-sea exploration difficult. While existing seabed observation networks, once built and covering the corresponding seabed, can address underwater communication issues with underwater communication nodes and sensors, their construction requires specialized vessels for cable laying, and underwater communication nodes require ROVs for underwater plugging and unplugging and maintenance. This presents significant construction challenges, requires substantial investment, and, since seabed observation networks typically extend from the shore into the ocean, they lack flexibility and struggle to cover deep-sea areas. Therefore, a deep-sea agile communication network and real-time detection system needs to be developed. Summary of the Invention

Detailed Implementation

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0023] like Figure 1The diagram shown is a structural schematic of an embodiment of the deep-sea agile communication network and real-time detection system of the present invention. This deep-sea agile communication network and real-time detection system includes a surface buoy system and an underwater system. The surface buoy system includes a buoy body 1, a battery unit 2, a cable 8 with a cable connector 3, a junction box 4, a cable winch 5, a solar charging panel 6, and a satellite communication unit 7. The battery unit 2, junction box 4, and cable winch 5 are located inside the buoy body 1. The cable 8 with the cable connector 3 is located at the bottom of the buoy body 1. The solar charging panel 6 and the satellite communication unit 7 are located at the top of the buoy body 1.

[0024] Cable 8 is wound on cable winch 5. One end of cable 8 is connected to satellite communication unit 7 through junction box 4, and the other end of cable 8 extends through cable 8 connector 3 and is connected to underwater system. Solar charging panel 6 is connected to battery unit 2 and is used to charge battery unit 2. Battery unit 2 is used to power junction box 4. Junction box 4 is connected to cable winch 5 and is used to control cable winch 5 to take in and release cable and self-lock.

[0025] It should be understood that the junction box 4 contains a main control circuit board, which can perform functions such as time data processing and control.

[0026] It should be noted that the surface buoy system is connected to the ground transceiver station via satellite communication. The underwater system is anchored to the seabed by ballast block 18. The optical-electric composite cable between the surface buoy system and the underwater system is a Kevlar braided zero-buoyancy cable with a breaking force of over 0.5 tons. With the locking of the winch and cable connector 3 of cable 8, the surface buoy system can be effectively kept on the sea surface directly above the underwater system, preventing the system from drifting due to wind, waves, and currents. It can also assist in the positioning of underwater targets.

[0027] The deep-sea agile communication networking and real-time detection system provided in this embodiment can be flexibly used in deep-sea areas where communication networking or detection is required. It has a high degree of integration, is easy to use and has low cost. It can be deployed / recovered using general-purpose marine vessels. A single system can cover thousands of square kilometers of seabed, and multiple systems can be easily networked to expand the scope of use. It can be flexibly deployed according to actual needs.

[0028] Once the surface buoy system is deployed to the water surface, the system's equipment is powered by battery unit 2, which is charged by solar charging panel 6 to ensure sufficient power. Satellite communication unit 7 communicates with the ground transceiver station via satellite for data and commands. Satellite communication unit 7 is interconnected with cable 8 through junction box 4, enabling the transmission and reception of data and commands with the underwater system. Cable winch 5 has cable winding, cable unwinding, and self-locking functions; it performs corresponding actions upon receiving a command from the main control circuit board in junction box 4.

[0029] Alternatively, in some possible implementations, cable 8 is a Kevlar braided zero-buoyancy cable.

[0030] Optionally, in some possible implementations, the underwater system includes: a buoyancy block 11, a lander frame 12, a deep-sea oil-filled junction box 13, an ARV 15, an ARV fixing mechanism 16, an underwater oil-filled battery pack 17, a microfiber cluster 19, a DAS underwater unit 20, an underwater acoustic communication unit 10, and a cable bearing head 9. The deep-sea oil-filled junction box 13 and the DAS underwater unit 20 are disposed in the first layer inside the lander frame 12, while the ARV 15, the ARV fixing mechanism 16, and the microfiber cluster 19 are disposed within the lander frame. The second layer inside the lander frame 12, the underwater oil-filled battery pack 17 is located in the third layer inside the lander frame 12, the buoyancy block 11 is located on the top of the lander frame 12, and the top of the buoyancy block 11 is equipped with an underwater acoustic communication unit 10 and a cable bearing head 9. The cable 8 extends into the interior of the lander frame 12 through the cable bearing head 9 and connects to the deep-sea oil-filled junction box 13. The deep-sea oil-filled junction box 13 is connected to the micro-fiber cluster 19, and the micro-fiber cluster 19 is connected to the ARV 15. The ARV 15 is mounted on the ARV fixing mechanism 16, wherein:

[0031] The underwater oil-filled battery pack 17 is connected to the underwater acoustic communication unit 10, the DAS underwater unit 20, and the deep-sea oil-filled junction box 13, and is used to power the underwater acoustic communication unit 10, the DAS underwater unit 20, and the deep-sea oil-filled junction box 13. The underwater acoustic communication unit 10 is interconnected with the cable 8 through the deep-sea oil-filled junction box 13, and is used to conduct underwater acoustic communication with targets within a preset range. The DAS underwater unit 20 is connected to the deep-sea oil-filled junction box 13, and is used to detect seabed vibrations. The deep-sea oil-filled junction box 13 is used to receive release commands from the ground transceiver station and transmit the release commands to the ARV 15 through the micro-fiber bundle 19. The ARV 15 is used to release the ARV fixing mechanism 16 according to the release command, and the thrusters of the ARV 15 move away from the underwater system.

[0032] Specifically, the acoustic release device 21 and the underwater acoustic communication unit 10 are installed on the upper end of the buoyancy block 11, and then the buoyancy block 11 is installed together on the top of the lander frame 12.

[0033] The top of the acoustic release device 21 is an acoustic transducer, the middle pressure chamber integrates a control circuit board and battery, and the lower part is a release mechanism. It can operate independently and is also connected to the deep-sea oil-filled junction box 13. The release mechanism is connected to the ballast block 18 at the bottom of the underwater system via a rope.

[0034] The cable bearing head 9, the deep-sea oil-filled junction box 13, the DAS underwater unit 20, the micro-fiber cluster 19, and the ARV15 are all mounted on the lander frame 12.

[0035] Cable 8 is connected to deep-sea oil-filled junction box 13 after being transferred through cable bearing head 9.

[0036] The underwater acoustic communication unit 10, the DAS underwater unit 20, the micro-fiber cluster 19, and the underwater oil-filled battery pack 17 are all connected to the deep-sea oil-filled junction box 13 to form an interconnection between the devices.

[0037] The deep-sea oil-filled junction box 13 has reserved surface sockets for communication and power supply, allowing for the addition of equipment such as CTDs, depth gauges, ADCPs, and hydrophones as needed. The deep-sea oil-filled junction box 13 contains power distribution circuit boards and control circuit boards, primarily used for equipment power distribution and the transmission and reception of commands and data.

[0038] The ARV15 is connected to the deep-sea oil-filled junction box 13 via a micro-fiber cluster 19. An acoustic communication unit is located on top of the ARV15, enabling underwater acoustic communication with other equipment. A ballast-fixed integrated support frame is located below the ARV15. The ARV15 includes a control electronics compartment and vector-mounted thrusters.

[0039] It should be noted that after the underwater system is deployed to the seabed, the underwater oil-filled battery pack 17 is connected to the deep-sea oil-filled junction box 13, mainly supplying power to the underwater acoustic communication unit 10, the DAS underwater unit 20, and the interfaces reserved on the deep-sea oil-filled junction box 13. The underwater acoustic communication unit 10 can cover a radius of approximately 15 kilometers on the seabed to achieve underwater acoustic communication interconnection with surrounding targets. The underwater acoustic communication unit 10 is interconnected with the cable 8 through the deep-sea oil-filled junction box 13, thus the underwater acoustic communication unit 10 can be connected to the satellite communication unit 7 to achieve real-time communication with the ground transceiver station.

[0040] The underwater system is equipped with 2-4 ARV15 units, depending on specific needs. When an ARV15 is required to operate, the ground transceiver station sends a command. The command is transmitted via satellite and cable 8 to the deep-sea oil-filled junction box 13, and then transmitted to the ARV15 via a microfiber spool 19. Upon receiving the command, the main control circuit inside the ARV15 triggers the ballast fixing bracket to release the ARV fixing mechanism 16. The thrusters on the ARV15 then activate, propelling it away from the underwater system. Depending on the command issued, the ARV15 can travel up to 30 kilometers away from the underwater system. The ARV15 is equipped with a battery pack, which powers the ARV15's underwater acoustic communication unit 10 for underwater acoustic communication. When the ARV15's battery is depleted or it receives a surfacing command, the ARV15 automatically cuts the microfiber spool and jettisons the ballast fixing bracket, using buoyancy to rise to the surface for recovery.

[0041] After the ARV15 of the underwater system extends into a micro-fiber cluster 19, it can detect seabed vibrations through the DAS underwater unit 20. It can be used for earthquake and tsunami forecasting, as well as for marine oil and gas detection, underwater target intrusion detection and location. The DAS underwater unit 20 is connected to the deep-sea oil-filled junction box 13, and the relevant data can be transmitted to the ground transceiver station in real time.

[0042] The acoustic release unit 21 is internally battery-powered and can operate completely independently. It is also connected to the deep-sea oil-filled junction box 13. When the underwater system needs to surface, the ground transceiver station can send commands via satellite to the satellite communication unit 7, which then transmits the commands to the acoustic release unit 21 via cable 8 to release the ballast block 18 of the underwater system. Alternatively, acoustic commands can be sent directly via the shipborne transducer. Upon receiving the acoustic commands, the acoustic release unit 21 can also release the ballast block 18. After releasing the ballast block 18, the underwater system rises to the surface under buoyancy, achieving recovery.

[0043] When multiple systems are used in a network, see Figure 2 :

[0044] Taking the networking between system a and system b as an example, both systems release ARVs. ARV a4 and ARV b2 can interconnect and network through underwater acoustic communication. The networking of multiple systems follows the same principle. When multiple underwater systems are networked, they can share a single surface buoy system. When the underwater target e approaches any lander or ARV, data communication can be completed.

[0045] Optionally, in some possible implementations, it also includes: an acoustic release device 21 and a ballast block 18. The acoustic release device 21 is located on the top of the buoy body 1 and connected to the deep-sea oil-filled junction box 13. The ballast block 18 is located at the bottom of the lander frame 12. The control mechanism of the ballast block 18 is connected to the acoustic release device 21. The acoustic release device 21 is used to receive the ascent command issued by the ground transceiver station when the underwater system needs to ascend, and release the ballast block 18 according to the ascent command to make the underwater system ascend.

[0046] Optionally, in some possible implementations, it further includes: an ARV underwater acoustic communication unit 14, which is disposed on the ARV 15 and is used to perform underwater acoustic communication with a target within a preset range.

[0047] Optionally, some possible implementations may include all or part of the above-described embodiments.
