Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

It should be further understood that the term "comprising" used in the specification of the present invention refers to the presence of the features, integers, steps, operations, elements and / or components, but does not exclude the presence or addition of one or more other features, integers, steps, operations, elements, components and / or groups thereof.
[0051] like Figure 2 As shown, the present invention constructs a maritime information highway through satellite, ship-side small station, ground master station and ground dedicated line data communication link, solves the problem of marine ship communication blind spots, allows each ship to use the network at sea like on land, and the crew can use telephone, WeChat, video, etc. at any time, while facilitating law enforcement ships to work online at sea. Equipped with a satellite resource scheduling management system for satellite broadband operation, scheduling and management.
[0052] The specific implementation of the present invention is described below with reference to the accompanying drawings and embodiments.
[0053] Example 1
[0054] This embodiment is based on the marine system highway composed of satellites, ship-side small stations, ground master stations and ground dedicated lines. Figure 3As shown in the figure, both the ship-side station and the ground master station can communicate with the satellite, and the ground master station transmits data with the ground headquarters through a ground dedicated line. When the ship is in the offshore section, it can directly communicate with the ground master station through the ship-side station. At the same time, within the communication range of the ship-side station, ships can also communicate directly with each other. In the communication blind area beyond the communication range of the equipment, the ship-side station and the ground master station establish a communication link through satellite to achieve communication without blind spots.
[0055] like Figure 1 As shown, the method for achieving no blind spot in marine ship communication provided by this embodiment includes the following steps:
[0056] S1: Using satellite communication technology, a satellite network covering the maritime area is established by launching multiple satellites to different orbital positions to provide high-speed data transmission and communication services;
[0057] S2: constructing shore-based base stations and gateways in coastal areas for connection and data exchange with the satellite network, and setting up marine base stations or buoys in the ocean as signal relay points to receive and forward satellite signals;
[0058] S3: Install advanced antenna technology and communication equipment on ships to ensure stable connection between ships and the satellite network;
[0059] S4: Use high-frequency electromagnetic waves and efficient modulation technology to improve the signal's ability to penetrate the ocean and obstacles;
[0060] S5: Manage the movement of ships by tracking their positions through mobile communication protocols and tracking technologies and with the help of satellite positioning systems.
[0061] Wherein, in step S1, by launching multiple satellites to different orbital positions, the satellite network is formed, and satellites with different orbital altitudes and inclinations provide full regional coverage, ensuring that signals can be received in all areas. This can increase the coverage of satellites on the earth's surface and reduce signal blind spots. Satellites with different orbital altitudes and inclinations can provide global or regional coverage, ensuring that signals can be received in all areas of the ocean.
[0062] Furthermore, step S2 specifically includes: establishing ground relay stations, namely the shore-based base stations and gateways, along the coast and at key locations. The relay stations receive satellite signals and amplify and forward them to enhance the coverage of signals on the earth's surface. The ground relay stations compensate for the attenuation of WeChat signals in certain areas, especially near the coastline or in areas with severe signal obstruction.
[0063] Specifically, in this embodiment, the shore-based base station includes: a satellite communication base station, a wireless network gateway, an optical fiber gateway, a microwave communication base station and an offshore communication platform;
[0064] The satellite communication base station is used to communicate with satellites, and usually includes a large-diameter satellite antenna, a high-power transmitter and receiver, and related signal processing equipment;
[0065] The wireless network gateway is used to connect the wireless network and other network devices, convert wireless signals into wired signals, and realize connection with other devices or networks;
[0066] The fiber optic gateway uses fiber optic communication technology to transmit data and is often used to connect shore-based networks and ships or offshore facilities;
[0067] The microwave communication base station uses microwave signals for communication and is suitable for short-distance marine communications, such as in ports or offshore areas;
[0068] The offshore communication platform, some specially designed offshore platforms or facilities, integrates multiple communication technologies and provides the shore-based base station and gateway functions to meet the needs of offshore communications.
[0069] Furthermore, the advanced communication equipment includes a satellite antenna and a communication terminal to ensure a stable connection between the ship and the satellite network, and the communication equipment includes: a very high frequency wireless communication device, a satellite communication system and an electronic chart system;
[0070] The VHF wireless communication equipment is used for short-distance communication, the satellite communication system performs long-distance communication via satellite, and the automatic identification system sends and receives the identity, position and dynamic information of the ship.
[0071] Specifically, in this embodiment, commonly used ship communication equipment includes very high frequency (VHF) wireless communication equipment, which can be used for short-distance communication, such as talking with ports, other ships or coastal radio stations. Satellite communication system, which can carry out long-distance communication via satellite, including telephone, fax, email, etc. Automatic identification system (AIS), which can send and receive the identity, location and dynamic information of the ship, and improve the safety of maritime traffic. In addition, there is also an electronic chart system (ECDIS) that can display electronic charts and navigation information to help crew members plan routes and navigate.
[0072] Furthermore, in step S4, in order to reduce signal attenuation and increase anti-interference capability, high-definition modulation and demodulation technology, signal enhancement technology and error correction coding, signal filtering and noise reduction, and sensor fusion methods are used to improve signal reliability.
[0073] Specifically, in this embodiment, the modulation and demodulation technology uses orthogonal frequency division multiplexing (OFDM) technology to divide the signal into multiple subcarriers for transmission, and improves the spectrum efficiency and anti-multipath interference capability through the orthogonality of the subcarriers. Multiple-input multiple-output (MIMO) technology is used to use multiple antennas for transmission and reception, increase the spatial diversity of the signal, and improve the anti-interference capability and data rate.
[0074] The signal enhancement technology uses a high-performance signal amplifier to enhance the power of the signal and compensate for the attenuation of the signal during transmission. Selecting a high-gain antenna improves the signal reception and transmission capabilities and reduces signal attenuation. By controlling the antenna beam, the signal is focused in a specific direction to improve signal strength and anti-interference capabilities.
[0075] The correction coding adopts Reed-Sol omon coding, detects and corrects multiple errors in the data stream, and improves the reliability of the data. The convolution coding technology is adopted to increase the error correction capability by introducing redundant information into the signal, which is suitable for the transmission of continuous data streams.
[0076] The signal filtering and noise reduction uses a suitable filter to filter the signal to remove the influence of noise and interference signals. Mean filtering, adaptive filtering and other algorithms are used to reduce the interference of noise on the signal.
[0077] The sensor fusion combines IMU data such as accelerometers and gyroscopes to assist in signal processing and improve the accuracy of positioning and attitude estimation. Acoustic sensors are used for sonar ranging or transmission of sound signals to increase signal diversity and reliability.
[0078] Further, in step S5, the mobile communication protocol is a mobile IP protocol, which ensures that the communication session is not interrupted by dynamically updating other network addresses when the ship moves, and the tracking technology includes a ship automatic identification system, radar tracking and radio communication to help with mobility management and communication link optimization;
[0079] The mobility management also includes: modulating the transmission direction of the signal by beamforming technology to focus the signal in the direction of the ship, and then automatically adjusting the beam direction of the antenna according to the position and movement of the ship by the intelligent antenna system;
[0080] Mobility prediction is performed by analyzing the movement trajectory and route information of the ship, which helps to plan the communication link in advance and predict possible signal interruption or weak coverage areas.
[0081] Specifically, in this embodiment, the position of the ship can be accurately determined using the Global Positioning System (GPS) or other similar satellite positioning technology. By installing a GPS receiver on the ship, the ship can obtain its own coordinate information in real time. Knowing the position of the ship in real time helps determine the best communication link and signal coverage.
[0082] At the same time, the mobile IP protocol allows the ship to maintain a connection to the network while moving. The mobile IP protocol ensures that the communication session is not interrupted by dynamically updating other network addresses when the ship moves. In this way, no matter how the ship moves, it can maintain continuous communication with the shore or other ships.
[0083] The tracking technology includes Automatic Identification System (AIS), radar tracking and radio communication, which can provide information such as the position, speed and heading of the ship, and help with mobility management and communication link optimization.
[0084] In addition, by establishing a wide network of maritime communication base stations and using satellite communication systems to provide a wider communication coverage, the ship can ensure the continuity of communication by communicating with the nearest base station or satellite no matter where it moves.
[0085] Furthermore, encryption technology, authentication and authorization mechanisms are used to protect data security:
[0086] Set strong passwords and change them regularly. Issue digital certificates to authorized users and devices for identity verification and secure connection establishment. Combine passwords with SMS verification codes and biometrics to improve authentication security.
[0087] Use SSL / TLS protocol to ensure that the communication between websites and applications is encrypted to prevent data from being eavesdropped during transmission. At the same time, use IPSec protocol to improve encryption and authentication at the network layer to protect the communication security between LANs.
[0088] Use professional security tools to scan systems and networks, identify potential security vulnerabilities and repair them in a timely manner. At the same time, establish an intrusion detection and defense system to monitor network traffic in real time, detect and prevent potential intrusions and attacks, and regularly analyze system and network logs to identify abnormal activities and potential security threats.
[0089] At the same time, an effective data management system is established to form a data warehouse for storing and processing the large amount of data generated at sea, analyzing data and providing decision support.
[0090] Use redundant systems and backup devices. When the main device fails, the backup device immediately takes over the communication function. At the same time, add network layer backup, establish multiple network connections and use different network service providers to ensure that even if one network fails, communication can still be carried out through other networks.
[0091] Backing up data to storage devices in different locations prevents local disasters or failures. The offsite part can provide an additional layer of protection to ensure data security and recoverability;
[0092] When the main device or network fails through the automatic switching mechanism, the backup device or network automatically takes over the communication function, which can reduce the time of human intervention and improve the recovery speed of the system;
[0093] Regularly monitor the status of the redundant systems and backup devices, including network connectivity, device performance, and data backup integrity. Perform regular testing to ensure the effectiveness and reliability of backup and redundant systems.
[0094] On the other hand, this embodiment provides a system for achieving no blind zone in marine ship communication, such as Figure 4 As shown, including:
[0095] A satellite network module, wherein the satellite network module uses satellite communication technology to establish a satellite network covering the maritime area by launching multiple satellites to different orbital positions, providing high-speed data transmission and communication services;
[0096] Base station and relay point module, the base station and relay point module is used to build shore-based base stations and gateways in coastal areas for connecting and exchanging data with the satellite network, and to set up marine base stations or buoys in the ocean as signal relay points to receive and forward satellite signals;

[0098] A signal modulation module, which uses high-frequency electromagnetic waves and efficient modulation technology to improve the signal's ability to penetrate the ocean and obstacles;
[0099] A mobile management module is used to track the position of the ship through mobile communication protocols and tracking technology and with the help of a satellite positioning system to perform mobile management of the ship.
[0100] Example 2
[0101] This embodiment develops various applications suitable for marine operations, including ship monitoring, navigation systems, communication tools, etc., and integrates them into the information highway.
[0102] Because the offshore environment is harsh, equipment is susceptible to corrosion, vibration, and temperature changes. To this end, choose durable and reliable communication equipment and perform regular maintenance and inspection.
[0103] Among them, durable materials are selected: stainless steel, aluminum alloy, ceramic lamps and other corrosion-resistant, wear-resistant and vibration-resistant materials suitable for the marine environment are selected to manufacture the housing and components of communication equipment; a high level of protection is adopted to ensure that the equipment can withstand the erosion of seawater, moisture, salt, etc., while preventing dust and moisture from entering the interior of the equipment; the equipment is reinforced and shock-proofed, and elastic supports and vibration reduction devices are installed to adapt to the vibration and turbulence environment of the ship.
[0104] At the same time, design an effective heat dissipation system to prevent the equipment from overheating. At the same time, select electronic components and assemblies that can adapt to a wide temperature range.
[0105] In terms of energy supply, the energy supply on board is limited, so energy saving and high-efficiency communication equipment need to be considered. Low-power communication technology, solar energy, wind energy and other renewable resources are used for power supply.
[0106] Finally, it should be noted that the above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments.
