Traditional ship management is limited to AIs, and it is impossible to know whether the ship has turned off AIs. Therefore, many illegal behaviors cannot be supervised. Most of them require law enforcement personnel to patrol and inquire before law enforcement. It is impossible to use a standardized system to conduct full-time, full-domain, and full-process detection, identification, and intelligent supervision of the waters in the jurisdiction area, and it is difficult to carry out three-dimensional prevention and control and command and dispatch in stages "before, during, and after the event".

Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments.

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.

[0050] like Figure 2 As shown, the present invention installs meteorological and hydrological data collection equipment, cameras, edge gateways and AIS data collection equipment on ships, which can provide important support for realizing intelligent management and control of ship terminals. Its composition is shown in the figure below, where the camera group is used for real-time monitoring and alarm of key parts and key events of the ship, the meteorological and hydrological data collection equipment realizes real-time monitoring of marine meteorological conditions, the ship-borne satellite communication system realizes satellite communication of the ship, and the AIS identification system realizes maritime traffic management. These devices are interconnected through the edge computing gateway.

[0051] The specific implementation of the present invention is described below with reference to the accompanying drawings and embodiments.

[0052] Example 1

[0053] First, Figure 1 As shown, this embodiment provides an intelligent management and control method for a large and medium-sized ship terminal, including:

[0054] Real-time detection of meteorological conditions through meteorological and hydrological data collection equipment provides important navigation information, while forecasting severe weather to ensure navigation safety, and planning routes based on the meteorological conditions data;

[0055] Through the camera, the key areas of the ship are monitored to understand the ship's operating status in real time, conduct safety monitoring of the ship, and detect key events;

[0056] Use edge gateways to act as a connection and conversion medium between different networks;

[0057] The AIS automatic identification system automatically sends and receives the ship's position, identity and speed information, helping ships to communicate and identify each other and between ships and shore-based management agencies.

[0058] The real-time detection of meteorological conditions by meteorological and hydrological collection equipment specifically includes:

[0059] The surrounding meteorological conditions are monitored in real time through the ship-mounted weather station, and then the marine meteorological radar is used to detect meteorological targets by transmitting and receiving electromagnetic waves, providing information on weather conditions and storm warnings. Satellite communication meteorological equipment is used to receive and transmit meteorological data and receive global meteorological information. The wind speed and direction are specifically measured through the wind vane and anemometer to assist in understanding the wind conditions, and finally the rainfall is measured through the rain gauge.

[0060] Furthermore, in this embodiment, the camera is used to monitor key areas of the ship, such as the deck, engine room, cargo hold, etc., to grasp the operating status of the ship in real time; it is used for ship safety monitoring, prevention of potential safety risks and accidents; and key event detection, such as ship berthing monitoring, cargo loading and unloading monitoring, crew behavior monitoring, etc.

[0061] Further, in this embodiment, the use of an edge gateway as a connection and conversion medium between different networks specifically includes:

[0062] Connect various sensors, devices and systems through the edge gateway, collect various data on the ship, perform preliminary processing and integration, and convert the data into a standard format or protocol;

[0063] By connecting to the ship's control system and monitoring equipment, the edge gateway can obtain the ship's status information in real time, such as engine operating parameters, cargo status, etc., and perform real-time control and adjustment according to the set rules or algorithms;

[0064] Connect and communicate the internal network of the ship with the external network. The edge gateway serves as the interface between the internal network of the ship and the external network (such as satellite communication, wireless network, etc.), realizes data transmission and communication, and ensures information interaction between the ship and shore-based facilities or other ships;

[0065] Data caching ensures data continuity and reliability when network connection is unstable or interrupted. At the same time, it can also perform some local data analysis and processing to reduce dependence on cloud computing resources;

[0066] Provide a certain security protection mechanism to isolate and control access to the ship network to prevent external malicious attacks and data leakage;

[0067] Manage and monitor connected devices, including device status monitoring, fault diagnosis, remote configuration, etc., to improve device reliability and maintenance efficiency.

[0068] Furthermore, the automatic sending and receiving of the position, identity and speed information of the vessel through the AIS automatic identification system specifically includes:

[0069] Using VHF radio signals to transmit data, each ship equipped with AI S equipment will periodically send data packets containing relevant information about itself, which can be received by other ships and shore-based receiving stations and displayed on electronic charts or other display devices.

[0070] Specifically, in this embodiment, AIS can provide real-time ship position and dynamic information, which helps to avoid collision accidents and improve navigation safety; at the same time, shore-based management agencies can use AIS data to monitor ship traffic, conduct traffic flow analysis and management, and improve waterway efficiency; in emergency situations, AIS can help determine the location and status of the ship, providing important information support for rescue operations; the use of AIS systems is usually part of regulatory requirements and helps ensure that ships comply with relevant navigation rules and regulations.

[0071] The AIS automatic identification system provides real-time ship position and dynamic information, and the data provided by the AIS automatic identification system is used to monitor ship traffic and conduct traffic flow analysis and management.

[0072] Furthermore, data transmission and sharing are achieved within the ship through wired communication, wireless communication, ship communication system, and industrial bus, and different communication methods and equipment are integrated through an integrated communication platform to achieve unified management and control.

[0073] Specifically, wired communication uses cables or optical cables to connect various components, such as laying communication lines between masts, cockpits, and work areas, and uses technologies including Ethernet and serial communication to transmit information such as data, control signals, and voice.

[0074] Wireless communication uses wireless communication technologies such as WI-FI, Bluetooth, ZigBee, etc. to establish a wireless network inside the ship. Each component can communicate through wireless access points or sensor nodes to achieve data transmission and sharing.

[0075] Among them, modern ships are usually equipped with special communication systems, such as ship communication radios, satellite communication equipment, etc. These systems can provide long-distance communication capabilities, including communication with shore-based facilities, other ships or maritime rescue agencies.

[0076] In this embodiment, we also use industrial bus technology, such as CAN (Controller Area Network) bus or PROFIBUS bus, to connect various devices and systems. This method can achieve efficient data transmission and control between devices.

[0077] Based on these communication methods, we use an integrated communication platform to integrate different communication methods and equipment to achieve unified management and control. This can improve the reliability and efficiency of communication. The specific communication implementation method may vary according to the design, requirements and technical selection of the ship. In practical applications, multiple communication methods are comprehensively considered to ensure that components in various locations can communicate and work together effectively. At the same time, electromagnetic compatibility, anti-interference ability and safety are taken into consideration to ensure stable and reliable communication.

[0078] In terms of data security, the communication data is encrypted and the data in transmission is encrypted using an encryption algorithm to ensure that the data is not stolen or tampered with by an unauthorized third party during the transmission process. In this embodiment, the specific measures are:

[0079] Use advanced encryption algorithms, such as AES (Advanced Encryption Standard) or RSA (Rivest-Shamir-Adlerman), to encrypt data in transit to ensure that data is not stolen or tampered with by unauthorized third parties during transmission;

[0080] At the same time, key management is used and keys are updated regularly, and hardware security modules and encrypted databases are used for secure storage, such as hardware security modules or encrypted databases;

[0081] Data at rest (stored data) should also be encrypted to prevent data leakage if the storage device is stolen or attacked.

[0082] In addition, a strict user authentication and authorization mechanism is implemented, including:

[0083] Implement multi-factor authentication, combining passwords, tokens, and biometrics for user authentication, and fine-grainedly assign access rights based on user roles and responsibilities to ensure that users can only access data and functions within their authorized scope. Regularly review and adjust user permissions to adapt to changes in organizational structure and business needs.

[0084] The implementation of user authentication and authorization mechanism also includes setting access control policies, including:

[0085] Establish an access control list (ACL) or role-based access control (RBCA) system to clearly define the specific access rights and permitted operations of different users on data, such as read, write, modify, delete, etc.

[0086] On this basis, the principle of least privilege is adopted to grant users only the minimum privileges required to complete their work, thus reducing potential risks.

[0087] At the same time, additional access controls are implemented for sensitive data, such as requiring special approval or two-person operation.

[0088] Before sharing data, the sensitive data shall be desensitized and the process and specifications for data desensitization and desensitization restoration shall be established, including:

[0089] Before sharing or integrating sensitive data into other systems, use data desensitization techniques such as replacement, encryption, hashing, etc. to process sensitive information to ensure data security and privacy;

[0090] Determine different data desensitization levels based on the sensitivity of the data and usage scenarios, such as full desensitization, partial desensitization or anonymization;

[0091] Establish data desensitization processes and specifications to ensure the repeatability and consistency of the desensitization process;

[0092] In cases where desensitized data needs to be restored, corresponding approval processes and security measures should be established to ensure that data restoration operations are authorized and monitored.

[0093] At the same time, the intelligent management and control method also includes regular data backup so that data can be restored in time when it is lost or damaged.

[0094] Record all operations and data access activities in the system for security audit and traceability. The specific measures are as follows:

[0095] Configure comprehensive security audit logs to record all operations and data access activities in the system, including user login, data reading, modification, deletion, etc.;

[0096] Real-time monitoring and analysis of audit logs to detect abnormal behaviors and potential security threats through machine learning or manual review;

[0097] Establish a response mechanism for security incidents.

[0098] At the same time, network security protection and intrusion detection and prevention systems are set up to prevent external attacks and data theft, vulnerability scanning and repair are carried out regularly, security holes in the system are discovered and patched in time, and real-time network segmentation is implemented to isolate different types of networks and reduce the spread of security risks.

[0111] The video surveillance module is installed on the deck, in the cabin, on the bridge and other locations to monitor the ship's surrounding environment, equipment operation or safety monitoring, helping the crew to detect problems in a timely manner.
