[0002] Unmanned engineering vessels refer to dredgers that achieve automated operations through intelligent systems and artificial intelligence technology. They can complete dredging tasks in waterways, ports, and other waterways without direct human intervention under specific working conditions. These vessels are typically equipped with a "one-click engineering" system and energy efficiency optimization algorithms. AI (Artificial Intelligence) autonomously controls the dredging depth, suction speed, and navigation path based on real-time hydrological and geological data, significantly improving operational safety and efficiency. The communication system of unmanned engineering vessels is a core component ensuring remote control, data transmission, and operational safety. Communication methods mainly include satellite, cellular networks (4G / 5G), radio (2.4GHz / 433MHz), long-range WiFi (Wireless Fidelity), and high-power wireless modules.

[0021] It is understood that before using the technical solutions disclosed in the various embodiments of this disclosure, users should be informed of the types, scope of use, and usage scenarios of the personal information involved in this disclosure in an appropriate manner in accordance with relevant laws and regulations, and user authorization should be obtained.

[0022] Example 1 This invention discloses a ship communication control method applied to both the ship and shore ends. The ship end can be, for example, an unmanned engineering vessel, and the shore end can be, for example, a shore control center. The ship and shore ends are respectively configured with a dual-channel communication architecture of wireless local area network (super WiFi access point) and mobile communication (4G / 5G communication), forming a primary and backup dual-redundant communication link between the ship and shore ends. Preferably, the super WiFi access point communication architecture serves as the primary communication link, and the 4G / 5G communication architecture serves as the backup / standby communication link.

[0023] Figure 1 This is a flowchart of a ship communication control method according to an embodiment of the present invention. This embodiment is applicable to the communication control of unmanned engineering vessels. The method can be executed by the ship communication control device in this embodiment, which can be implemented in software and / or hardware, such as... Figure 1 As shown, the method specifically includes the following steps: S101. Obtain the communication scenario data corresponding to the first link, which serves as the main communication link, and determine the communication quality score corresponding to the first link based on the communication scenario data.

[0024] It should be noted that the first link can be the current communication architecture that serves as the main communication link, such as a wireless LAN (super WiFi access point) communication architecture or a mobile communication (4G / 5G communication) architecture. In specific implementation, it is preferable to use the wireless LAN (super WiFi access point) communication architecture as the main communication link.

[0025] In this embodiment, the communication scenario data can be relevant data when communicating between the ship and the shore.

[0026] The communication scenario data includes signal strength, bandwidth utilization, and environmental parameters.

[0027] It should be noted that the communication quality score can be a score used to assess the health status of a communication link.

[0028] Specifically, during communication between the ship and shore, communication scenario data, including signal strength, bandwidth utilization, and environmental parameters, are collected in real time through continuous heartbeat packets. Using multi-sensor fusion technology, the communication quality score corresponding to the first link is determined, and the health status of the communication link is dynamically assessed.

[0029] S102. If the communication quality score corresponding to the first link is lower than the target score threshold, then the communication link is switched: the second link is enabled as the primary communication link, and the first link is used as the backup communication link.

[0030] The target score threshold can be a pre-set threshold based on actual conditions or experience, used to determine the health status of the communication link. For example, when the communication quality score of the link reaches the target score threshold, the link is considered to be communicating normally; when the communication quality score of the link is lower than the target score threshold, the link is considered to be communicating abnormally (abnormal communication may include: sudden signal interruption, weakened signal strength, increased signal interference, etc.). This embodiment does not specify a specific value for the target score threshold.

[0031] It should be noted that the second link can be another link in the primary and backup dual-redundant communication links besides the first link. For example, when the first link is a wireless LAN (super WiFi access point) communication architecture, the second link can be a mobile communication (4G / 5G communication) architecture; when the first link is a mobile communication (4G / 5G communication) architecture, the second link can be a wireless LAN (super WiFi access point) communication architecture.

[0032] Specifically, when the main communication link fails, an intelligent communication link switching decision can be made: switch the mobile communication (4G / 5G communication) architecture as the main communication link and the wireless LAN (super WiFi access point) communication architecture as the backup communication link.

[0033] S103. Communication between the ship and shore is based on the switched main communication link.

[0034] Specifically, the ship-side and shore-side control systems utilize a data transmission mechanism based on a custom link-layer protocol, optimizing data packet structure and retransmission strategies to reduce end-to-end data latency for subsequent data transmission and reception. Ship-side and shore-side signal transceiver equipment send and receive command and data signals, enabling signal transmission and reception interaction and facilitating communication between the ship and shore.

[0035] This invention employs a dual-channel communication architecture, configuring both a wireless local area network (WLAN) and mobile communication at the ship and shore ends respectively, to form a primary and backup redundant communication link between the ship and shore. It acquires communication scenario data corresponding to the first link (serving as the primary communication link) and determines the communication quality score based on this data. The communication scenario data includes signal strength, bandwidth utilization, and environmental parameters. If the communication quality score of the first link is lower than a target threshold, a communication link switch is performed: the second link is activated as the primary communication link, and the first link is used as a backup. Communication between the ship and shore is then conducted based on the switched primary communication link. This invention overcomes the problem of communication interruption caused by signal blockage or interference on a single communication link, ensuring the continuous controllability of unmanned engineering vessels under various operating conditions.

[0036] In actual operation, the initialization phase requires the loading and running of programs in the ship-end and shore-end control systems. Its main function is to set the initial state (the initial state of various software and sensors in the ship-end and shore-end), allocate resources (allocate communication link resources), create objects (objects that need to communicate), or perform necessary configuration operations (set various data).

[0037] Optional environmental parameters include: sea state information and electromagnetic interference; sea state information includes: temperature, light intensity, wind speed, humidity, rainfall, and wave height.

[0038] The communication quality score corresponding to the first link is determined based on communication scenario data, including: The various types of data contained in the communication scenario data are processed for time alignment and spatial alignment to obtain the data to be fused.

[0039] In the specific implementation process, time alignment can be performed first. For example, for signal strength, a raw frequency of 10 times / second can be used, and the alignment method can be direct averaging; for network latency, a raw frequency of 10 times / second can be used, and the alignment method can be direct sampling; for temperature and humidity, a raw frequency of 1 time / minute can be used, and the alignment method can be interpolation padding (filling in intermediate moments with predicted values); for wave height and wind speed, a raw frequency of 1 time / 10 minutes can be used, and the alignment method can be Kalman smoothing. Finally, all data is aligned to the same time axis, for example, one data point every 100 milliseconds.

[0040] Next, spatial alignment is required. Since the sensors are distributed in different locations (on ships, buoys, underwater, etc.), they need to be mapped to the locations traversed by the communication link. A specific approach could be to draw the sea surface as a grid, use interpolation algorithms to convert discrete sensor data into continuous values ​​along the link path, and consider the influence of ocean currents to correct for buoy drift.

[0041] After normalizing each piece of data to be merged, a weighted sum is performed to obtain the communication quality score corresponding to the first link.

[0042] In practice, weights can be set for each piece of data to be fused. For example, a weight of 40% can be set for signal quality (including signal strength, bit error rate, and signal-to-noise ratio), a weight of 30% can be set for network performance (including bandwidth utilization, latency, and packet loss rate), and a weight of 30% can be set for environmental adaptability (including wave height, rainfall, temperature, and electromagnetic interference). Specifically, the weight values ​​can be dynamically adjusted according to changes in the scenario.

[0043] Optionally, the ship and shore ends use a unified clock source and trigger signal for data transmission and reception.

[0044] Specifically, the ship and shore ends use a unified clock source and trigger signal for data transmission and reception, achieving phase alignment and sampling synchronization of signal channels between the signal output terminals of multiple peripheral devices of the ship and shore control systems and the signal interaction terminals of the control system, thus ensuring the consistency of data interaction between the ship and shore ends.

[0045] In practical operation, low-latency SRIO (Serial Rapid I / O) reliable transmission and DMA (Direct Memory Access) data transmission schemes can be adopted to ensure the low-latency transmission performance of system data.

[0046] During data transmission and reception, the sequential verification of transmitted data between the ship and shore is performed based on a cyclic redundancy check and sequence number confirmation mechanism.

[0047] In actual operation, the received data is buffered and subjected to preliminary filtering and data format conversion. A CRC (Cyclic Redundancy Check) verification and sequence number confirmation mechanism is introduced to ensure that the data is delivered to the ship-side and shore-side control system's own application programs in the correct order.

[0048] The sequence number is a unique number assigned to each byte in the data stream to identify the position of the data in the overall stream. The acknowledgment mechanism is that the receiver uses the sequence number to reorder out-of-order data packets.

[0049] Optionally, the method further includes: During the data transmission and reception process, the target encryption algorithm is used to encrypt the transmitted data.

[0050] In this embodiment, the target encryption algorithm may be, for example, the AES-128-bit (Advanced Encryption Standard-128 bit) encryption algorithm.

[0051] Specifically, the AES-128-bit encryption algorithm can be used to encrypt the transmitted and received data end-to-end. The MAVLink (Micro Air Vehicle Link) protocol stack is integrated to ensure standardized encapsulation and parsing of commands and data during transmission, compatibility with heterogeneous control systems, and real-time monitoring of data strength and bit error rate. Even if data packets have different paths and arrive in disorder in the network, they can be correctly reassembled to ensure the reliability of subsequent data transmission.

[0052] Optionally, the method further includes: During the communication link switching process, the target protocol stack is used to synchronize data between the primary and backup dual redundant communication links.

[0053] In this embodiment, the target protocol stack can be a TCP (Transmission Control Protocol) / IP (Internet Protocol Stack) protocol stack.

[0054] Specifically, a TCP / IP protocol stack can be used to achieve data synchronization between primary and backup dual redundant communication links. During the switchover process, a buffer mechanism is used to temporarily store data (the core implementation logic of the buffer mechanism is to allocate a memory area between high-speed processing units (such as CPU (Central Processing Unit)) and low-speed devices (such as disks and networks) as a "transfer station". Through the strategy of "temporarily storing first and then batch processing", frequent single operations are merged into efficient batch operations, thereby solving the speed mismatch problem and improving system throughput), avoiding information loss, supporting multi-ship collaborative operation, and ensuring the continuity of cluster communication.

[0055] Optionally, after establishing communication between the ship and shore based on the switched main communication link, the following may also be included: Perform a signal quality assessment on the primary and backup communication links after the switchover.

[0056] In actual operation, the communication data of the switched link and the original communication link are evaluated.

[0057] If the signal quality of the primary communication link after the switch is weaker than that of the backup communication link, the communication link switch will be performed again: the first link will be activated as the primary communication link, and the second link will be used as the backup communication link.

[0058] Specifically, when the communication quality of the new communication link is weaker than that of the original communication link, the communication link will be switched back to the original communication link.

[0059] Compared with existing technologies, the technical solution of this invention, through multi-link collaboration, can cover all operational scenarios from nearshore to open ocean. By continuously monitoring the signal quality and connection status of the primary super WiFi link through heartbeat packets, when the signal strength is detected to be below the threshold or the link is interrupted, the communication session is automatically and seamlessly switched to the backup 4G / 5G link. The entire process requires no manual intervention and can maintain the session status without loss. It has strong fault self-healing capabilities, significantly improves operational safety, and real-time data transmission supports intelligent operation, reduces labor costs, effectively overcomes the problem of communication interruption caused by wireless signal obstruction or interference, and ensures the continuous controllability and operational safety of unmanned engineering vessels under various working conditions.

The device can be implemented using software and / or hardware, and can be integrated into any device that provides ship communication control functions, such as... Figure 2 As shown, the ship communication control device specifically includes: an acquisition and determination module 201, a communication link switching module 202, and a communication module 203.

[0061] The acquisition and determination module 201 is used to acquire communication scenario data corresponding to the first link, which serves as the main communication link, and determine the communication quality score corresponding to the first link based on the communication scenario data; the communication scenario data includes: signal strength, bandwidth utilization, and environmental parameters.

Communication module 203 is used for communication between the ship and shore based on the switched main communication link.

[0062] Optionally, the environmental parameters include: sea state information and electromagnetic interference; the sea state information includes: temperature, light intensity, wind speed, humidity, rainfall, and wave height. The acquisition and determination module 201 is specifically used for: The various types of data contained in the communication scenario data are subjected to time alignment and spatial alignment processing to obtain the data to be fused.
