Description

Technical Field

[0001] This utility model relates to the field of marine communication and maritime support technology, specifically to a mobile and berthable marine transportation and communication platform transfer station vessel (hereinafter referred to as "communication transfer vessel"). By integrating multi-band communication technology, dynamic positioning technology and distributed network collaboration technology, it constructs an integrated communication hub for both offshore and near-shore areas, solving the coverage blind spot problem of existing marine communication systems that rely on shore-based systems for near-shore operations and satellite systems for offshore operations, and improving the communication stability and signal strength for maritime transportation, scientific research operations, and emergency rescue. Background Technology

[0002] Currently, marine communication mainly relies on two types of methods:

[0003] 1. Shore-based base stations: only cover near-shore areas 50-100 kilometers from the shore, the signal attenuates rapidly with distance, and is completely ineffective in the open sea;

[0004] 2. Satellite communication: Due to limitations of satellite orbital resources, bandwidth is limited (single link is usually ≤100Mbps), and signals are easily interrupted in severe weather such as rainstorms and typhoons, with latency as high as 200-500ms, which cannot meet real-time requirements (such as centimeter-level positioning data transmission for autonomous ships).

[0005] 3. Existing mobile platforms (such as fishing boats and supply ships): lack dedicated communication relay equipment, have low signal transmission power (≤5W), coverage radius ≤10 kilometers, and the signal is unstable due to the swaying of the hull, making them unsuitable as fixed communication nodes.

[0006] In summary, existing technologies suffer from core pain points such as "insufficient coverage in the open sea, poor signal stability, and low real-time performance," and there is an urgent need for a marine communication relay platform that can actively fill blind spots, enhance signals, and be flexibly deployed.

The left and right sides of the semi-submersible pontoon 102 are respectively connected to an underwater acoustic positioning beacon 4 and a wind and wave sensor 5. The coverage range is improved: it solves the communication blind spot in the far sea. The coverage radius of a single ship is 300 kilometers, which is 3-6 times that of the existing shore-based base stations. The multi-ship network can cover a far sea area of ​​more than 1,000 kilometers. The top of several floating platform plates 2 is connected to a side plate 38. The top of several side plates 38 is connected to the same platform 39. The top of the platform 39 has a connecting port 40.

[0041] In this embodiment, the top of the semi-submersible pontoon 102 is connected to a shell 3 near the left and right sides, and the bottom of the shell 3 is open. Worm gears 33 are respectively installed inside the shell 3 near the front and rear sides. The bottom of the worm gears 33 is bolted to a docking shaft 34. The bottom end of the docking shaft 34 is movably connected to the semi-submersible pontoon 102 via a bearing. The bottom end of the docking shaft 34 passes through the inner ring of the bearing and is connected to the top of the permanent magnet synchronous thruster 32. Worms 35 are meshed on one side of each of the two worm gears 33. The two worms 35 are welded together, and both ends of the worms 35 are movably connected to the inner wall of the shell 3 via bearings. The front side of the shell 3 is connected to... A drive motor 6 is bolted to the top of the deck 17, and the front end of the worm gear 35 is connected to the output shaft of the drive motor 6. The top of the deck 17 is bolted to the box 12, and the right side of the box 12 is open. A lifting block 29 is slidably connected inside the box 12. The lifting block 29 has a threaded hole, and a lead screw 28 is fitted inside the threaded hole. The top and bottom ends of the lead screw 28 are respectively movably connected to the top and bottom of the inner cavity of the box 12 through bearings. The signal strength is improved: through high-power transmission, intelligent beamforming and anti-fading technology, the signal strength is enhanced by 20-30dB compared with the existing satellite communication. The communication interruption rate under bad weather is reduced from 30% to less than 1%.

[0042] Implementation plan: A servo motor 30 is bolted to the bottom of deck 17, and the bottom end of lead screw 28 is connected to the output shaft of servo motor 30. A docking plate 31 is bolted to the right side of lifting block 29, and the right side of docking plate 31 is bolted to communication mast 13.

[0043] Working principle: In use, the servo motor 30 first drives the lead screw 28 to rotate forward or reverse, and with the cooperation of the threaded hole, the lifting block 29 slides up or down in the housing 12. The lifting block 29 drives the communication mast 13 and antenna unit 14 to move up or down through the docking plate 31, which can adjust the height and vertical position of the communication mast 13 and antenna unit 14 to adapt to different signal coverage ranges. The drive motor 6 drives the worm gear 35 to rotate, and the worm gear 35 drives the worm wheel 33 to rotate. The worm wheel 33 drives the permanent magnet synchronous propeller 32 to rotate through the docking shaft 34, which can realize 360° conversion of the permanent magnet synchronous propeller 32 to adapt to propulsion in different directions. It can be moored and moved, with a positioning accuracy of ≤1m, and adapts to the communication needs of different scenarios (fishing grounds, shipping routes, emergency rescue).

[0044] Example 2

[0045] like Figures 1 to 13 As shown, a mobile, dockable marine transportation and communication platform transfer station vessel:

[0046] (I) Overall Architecture

[0047] The communication transfer vessel adopts a three-tiered structure consisting of a catamaran semi-submersible platform, a modular communication cabin, and an intelligent control system.

[0048] Platform body: catamaran hull (50m long × 30m wide), with a semi-submersible pontoon at the bottom (draft 8-10m). It achieves attitude stability within ±2° through anti-roll fins and active ballast system (meeting the stability requirements of communication equipment).

[0049] Communication module layer: The deck is equipped with a liftable communication mast (30m high), an omnidirectional antenna array and a satellite transceiver cabin, which integrates a multi-band signal processing unit;

[0050] Control and Energy Layer: The shipboard central control system links the power, positioning, and energy modules to achieve autonomous berthing / movement and coordinated operation of equipment.

[0051] (II) Technical solutions for key subsystems

[0052] 1. Platform Body and Dynamic Positioning System – The Foundation for Achieving “Stopping and Moving”

[0053] Hull design: The catamaran structure reduces water resistance, and the semi-submersible pontoons have 6 active ballast tanks (each with a volume of 50m³) that can counteract the tilting caused by wind and waves by adjusting the water volume in the tanks in real time (response time ≤10s); the deck is made of anti-slip and anti-corrosion aluminum alloy, and the communication mast is equipped with a hydraulic lifting device at the bottom (the height can be adjusted according to the wind speed: it can be raised to 30m when the wind speed is ≤15m / s and lowered to 15m when the wind speed is ≥20m / s to avoid equipment damage).

[0054] Power system: It adopts 4 permanent magnet synchronous propulsion units (500kW each), which are respectively arranged on both sides of the stern of the catamaran, supporting 360° rotation and turning on the spot (turning radius ≤5m); the range is ≥30 days (with a 100m³ diesel tank + clean energy replenishment).

[0055] Dynamic Positioning (DP) System: Integrates GPS / BeiDou dual-mode positioning (accuracy ±0.5m), underwater acoustic positioning beacon (auxiliary positioning within 1000m underwater) and wind and wave sensors. The system calculates the hull offset in real time through the central control system (sampling frequency 10Hz) and drives the thrusters to dynamically correct the position. The positioning accuracy is ≤1m when berthed (meeting the stability requirements of the communication antenna beam pointing).

[0056] 2. Multi-band communication system – the core of signal enhancement and multi-scenario coverage

[0057] Core objective: To achieve full-scenario signal coverage from nearshore to offshore, supporting three types of needs: maritime communication (VHF / UHF), broadband data (5G / 6G), and emergency communication (satellite relay), with a signal coverage radius of ≥300 kilometers (open sea area).

[0058] (1) Ground link module - near-shore high-bandwidth communication

[0059] 5G / 6G base station unit: Equipped with a three-band active antenna array (Sub-6GHz: wide coverage; millimeter wave: high bandwidth), with a transmit power of 50W (10 times that of ordinary shore-based base stations), and dynamically adjusts the signal direction through "intelligent beamforming" technology.

[0060] For areas with dense shipping traffic (such as fishing grounds and shipping routes), the beam can be automatically focused (the beam width can be reduced to 5°) to improve the local signal strength (20-30dB stronger than the existing signal).

[0061] For moving vessels, AI algorithms are used to predict the vessel's trajectory (based on AIS navigation data) and adjust the beam pointing in advance (prediction accuracy ±10m) to avoid signal switching interruptions.

[0062] Maritime dedicated frequency band (VHF / UHF): Integrates 2 maritime VHF radios (transmit power 25W), supports DSC (Digital Selective Calling) and AIS data forwarding, with a coverage radius of ≥50 kilometers, meeting the routine communication needs of fishing vessels and merchant ships; at the same time, it reserves a UHF frequency band interface, which can be connected to the maritime bureau's emergency communication network.

[0063] (2) Satellite relay module - signal gap filling in the open sea

[0064] Low Earth Orbit (LEO) satellite transceiver compartment: Equipped with a phased array satellite antenna (2.4m aperture), it supports docking with LEO satellite constellations such as "Starlink" and "Hongyan", with a link bandwidth of ≥500Mbps (5 times that of traditional geostationary satellites) and latency ≤50ms; through "multi-satellite switching" technology (simultaneously tracking 3 satellites), it avoids signal interruption caused by a single satellite passing over the area (switching time ≤1s).

[0065] Emergency satellite backup: Equipped with one geostationary satellite (GEO) terminal (1.2m aperture) as a backup in case of LEO satellite failure. Although the bandwidth is low (≤20Mbps), the coverage is stable (not affected by satellite orbit) to ensure the transmission of emergency commands.

[0066] (3) Signal processing and enhancement technology – improving anti-interference capability

[0067] Adaptive frequency hopping technology: In response to the complex marine electromagnetic environment (such as radar and fishing boat radio interference), it monitors the frequency band interference intensity in real time (sampling frequency 100Hz) and automatically switches to the interference-free frequency band (frequency hopping rate ≥1000 times / second), with an interference suppression ratio ≥40dB.

[0068] Distributed MIMO (Multiple-Input Multiple-Output): The communication mast is equipped with 8 antenna units (arranged in a ring). The same signal is transmitted through different paths using "spatial diversity" technology. The receiver combines the signals using an algorithm to compensate for signal fading caused by the ship's rolling (fading compensation rate ≥90%).

[0069] Edge computing node: The cabin integrates an edge server (100 TOPS computing power) to process real-time ship data (such as navigation and equipment status) locally before uploading it, reducing the amount of data transmitted back (compression ratio ≥10:1), reducing the load on the satellite link, and reducing the data response latency from 500ms to less than 20ms.

[0070] 3. Energy System – Ensuring Continuous Equipment Operation

[0071] A hybrid power supply system combining traditional and clean energy sources is employed to meet the continuous power requirements of communication equipment (peak power consumption 50kW) and shipboard systems (peak power consumption 30kW).

[0072] Main power source: 2 diesel generators (100kW each), with fuel tank capacity sufficient for 15 days of full-load operation;

[0073] Clean energy replenishment: Flexible solar panels (200㎡ area, 23% conversion efficiency) are laid on the deck, and two vertical axis wind turbines (5kW each) are installed. On sunny days with wind speeds ≥5m / s, they can provide 30kW of power (meeting 60% of the power consumption of communication equipment).

[0074] Energy storage system: Equipped with a lithium iron phosphate battery pack (capacity 500kWh), it can seamlessly switch power supply when the diesel generator stops or clean energy is insufficient (switching time ≤10ms) to ensure uninterrupted communication equipment.

[0075] 4. Intelligent Control System – Enabling Autonomous Operation and Remote Collaboration

[0076] Local autonomous control: Based on PLC (Programmable Logic Controller) and AI algorithm, the following is achieved: Attitude adaptive adjustment: By using wind and wave sensors (collecting wind speed, wave height, and hull tilt angle), the ballast tank water volume and anti-roll fin angle are automatically controlled to maintain the verticality deviation of the communication mast ≤0.5°.

[0077] Equipment fault self-diagnosis: Real-time monitoring of parameters such as voltage, current, and temperature of communication module and power system (≥100 monitoring points). When an abnormality is detected, it automatically switches to backup equipment (e.g., if the main antenna fails, it switches to the backup antenna within 10 seconds) and triggers an alarm.

[0078] Path planning: Based on preset communication tasks (such as "move to sea area A to enhance signal"), combined with nautical charts and meteorological data (access to real-time data from the State Oceanic Administration), autonomously plan the optimal route (avoiding reefs and typhoon areas), with a movement accuracy of ±50m.

[0079] Shore-based remote monitoring: Establishes encrypted communication with the shore-based control center via satellite link (using the SM4 national cryptographic algorithm), supporting:

[0080] Real-time status monitoring: The shore-based system can view the location, attitude, and equipment operation data of the transfer vessel (update frequency 1Hz);

[0081] Remote command issuance: If communication parameters need to be adjusted (such as switching satellite frequency bands or focusing on a specific area beam), the shore-based system can be operated remotely (command transmission delay ≤10s).

[0082] Multi-ship coordinated scheduling: When the coverage of a single ship is insufficient, the shore-based system can control multiple transit ships to form a "communication grid" (such as 3 ships arranged in a triangle). The signal relay is achieved through the inter-ship Mesh network (using 60GHz millimeter wave, bandwidth 10Gbps, transmission distance 50km), and the coverage range is extended to more than 1000km.

[0083] (III) Collaborative Working Mode

[0084] 1. Mooring mode: When it is necessary to enhance the signal in a certain area (such as fishing grounds or offshore operation areas), the transfer vessel moors at the target location through the DP system, raises the communication mast to the highest point, and provides omnidirectional coverage with the antenna array. At this time, it can be used as a "floating shore-based base station". Ships within 300 kilometers can access the 5G network with a bandwidth of ≥100Mbps and latency of ≤20ms.

[0085] 2. Moving mode: When dynamic blind spot filling is required (such as tracking ocean-going fleets), the transfer vessel moves along the planned path and continuously aligns with the target fleet through beamforming technology to ensure that the signal is not interrupted during the movement (beam switching time ≤ 50ms).

[0086] 3. Multi-ship networking mode: When three or more transit ships work together, they form a "distributed communication grid" through the inter-ship Mesh network. The coverage radius of a single ship is 300 kilometers. After networking, the coverage area is superimposed, and when a single link fails, it automatically switches to other ships as relays, increasing the redundancy to 99.99%. Specific Implementation

[0087] One communication relay vessel will be deployed and stationed in the center of the fishing grounds (30°N, 125°E), with its position fixed via a DP system;

[0088] The communication mast was raised to 30m, the 5G base station was put into use in the Sub-6GHz band (covering a wide area), and the beamforming was focused on the core area of ​​the fishing ground (approximately 500 square kilometers).

[0089] At the same time, the LEO satellite relay is activated to connect with the Starlink satellite as a backup link for fishing vessels in the open sea;

[0090] In actual operation, fishing boats within 200 kilometers of the fishing grounds can access the 5G network with a download speed of ≥50Mbps, enabling real-time transmission of catch data and reception of weather warnings; fishing boats 300 kilometers away can use satellite relay communication with a latency of ≤50ms, which is 10 times faster than traditional satellite communication.

[0091] This solution constructs a "floating hub" for marine communication through "hardware modularization + technology collaboration + intelligent control," which can be widely used in maritime transportation, marine scientific research, emergency rescue and other fields, and has significant technological advancement and practical value.
