Description

Technical Field

[0001] The present application relates to the technical field of ship counterfeit license plate identification, and in particular to a ship MMSI encoding and counterfeit license plate identification method and system, and a readable storage medium. Background Art

[0002] MMSI (Maritime Mobile Service Identity) is a ship identification code developed and promoted by the International Maritime Organization. The design purpose of this code is to set a unique identification mark for each ship sailing in the world's waters to achieve accurate and rapid identification and positioning. As an important means of ship identification, the MMSI coding system plays an indispensable role in ship communication, monitoring and management. The MMSI code is usually composed of 9 digits, which gives each ship a unique identification code. The design of this coding system fully considers global compatibility and practicality, ensuring that there will be no confusion and conflict in maritime communications between different countries and regions. In practical applications, MMSI coding is widely used in ship radio communications, automatic identification systems, ship traffic services, distress and emergency calls, etc., enabling maritime administration departments of various countries to efficiently perform supervision and monitoring of ships. Through MMSI coding, maritime administration departments can track the dynamics of ships in real time, including their location, heading, speed and other information, which is crucial for maintaining maritime traffic order and preventing ship traffic accidents. In addition, when a ship encounters an emergency, the MMSI code can help the rescue department quickly locate the distressed ship, launch effective rescue operations in a timely manner, and maximize the safety of the ship and crew. Therefore, the MMSI code is not only a ship's identity, but also an important tool for the International Maritime Organization to ensure global maritime safety and efficiency.

[0003] Traditional ship identification methods mainly rely on manual input and verification of MMSI codes. However, this method has problems such as low efficiency and high error rate. Especially in sea areas with a large number of ships and frequent communications, manual identification methods often have difficulty in coping with a large amount of data input and comparison work, which can easily lead to mis-input and duplication of license plates.

Finally, the MMSI code is format-checked by a regular expression or a preset coding rule. Specifically, by configuring a dedicated receiver, it is ensured that ship data from different communication channels can be received. The receiver should have decoding capabilities to convert the received signal into processable digital data. The user can input the ship information through the AIS terminal loaded on the ship. It is then sent out in the form of a broadcast, and the relevant receiving device extracts the MMSI code from the received ship data and performs a format check to ensure the integrity and accuracy of the code.

[0040] In this embodiment, the MMSI code is checked for complexity by using preset check rules, and the check result is obtained by scoring or classifying the MMSI code by using preset check rules. Specifically, the preset check rules include checking whether the MMSI code is a repeated number, a continuous sequence, and a specific combination.

MMSI codes with obvious regularity are analyzed and marked, and these codes are more strictly input verified and monitored in real time. This special mechanism can more effectively identify potential risks of counterfeiting and take preventive measures in advance.

[0050] The embodiment of the fourth aspect of the present application provides a readable storage medium on which a program or instruction is stored. When the program or instruction is executed by a processor, the steps of the ship MMSI encoding and duplicate license plate identification method of any one of the embodiments of the first aspect are implemented, so it has the technical effect of any one of the embodiments of the first aspect mentioned above, and will not be repeated here.

[0051] like Figures 10 to 15As shown, according to a specific embodiment of the ship MMSI coding and duplicate license plate identification method provided by the present application, it is possible to automatically perform format verification when the user enters the MMSI number to detect whether there are common confusing patterns (such as consecutive identical numbers, repeated number sequences, etc.). Once a potential error is found, the system will immediately issue a warning and provide correct number suggestions or guide the user to re-enter. In addition, the system can also be integrated into the existing ship management system to achieve automated monitoring and early warning, solve the problem of duplicate license plates caused by the easy-to-remember and easy-to-mistype MMSI codes in the ship field, ensure the accuracy and security of ship communications, maintain maritime traffic order and emergency response capabilities, identify and prevent the mis-entry and duplicate license plate behaviors of MMSI codes through technical means, reduce the risks caused by this, and ensure the safety of ship navigation.

[0052] This embodiment will strengthen the ship identity authentication and tracking mechanism.

[0053] Through the comprehensive application of special error-prone coding recognition algorithms, dynamic risk assessment and early warning systems, and multi-factor verification mechanisms, this solution can significantly reduce the phenomenon of mis-entry caused by easy-to-remember and easy-to-enter codes, and effectively curb the use of counterfeiting. This will greatly improve the accuracy and reliability of ship identity recognition and ensure the effectiveness and safety of maritime traffic management. The dynamic risk assessment and early warning system can monitor the dynamic changes of ships in real time and immediately trigger early warnings when abnormal behavior is found. This enables management departments to obtain ship information more quickly and accurately, and take necessary measures in a timely manner to deal with potential safety risks. At the same time, the multi-factor verification mechanism also reduces false alarms caused by mis-entry or counterfeiting, and improves the work efficiency and response speed of management departments. This embodiment will promote the healthy development of the shipping industry, protect the rights and interests of legitimate ships, and maintain a fair competition environment in the market by reducing mis-entry and counterfeiting. At the same time, the improvement of the accuracy and reliability of ship identity recognition will also enhance the security and credibility of the entire industry and promote the sustainable development of the industry.

[0054] Specifically, the ship MMSI coding and fake license plate identification method includes the following specific steps: S1: System reception and analysis. The system monitors VHF broadcast communications, AIS messages transmitted by the AIS system, and ship-related information in satellite communications in real time. Configure a dedicated receiver to ensure that ship data from different communication channels can be received. The receiver should have decoding capabilities to convert the received signal into processable digital data. Users can enter ship information through the AIS terminal mounted on the ship. It is then sent out in the form of a broadcast, and the relevant receiving equipment extracts the MMSI code from the received ship data and performs a format check to ensure the integrity and accuracy of the code. Develop a data parsing module to extract the MMSI code field according to the AIS message format, VHF communication protocol or satellite communication protocol. Use regular expressions or preset coding rules for format verification.

[0055] S2: Complexity check. Perform a complexity check on the extracted MMSI code to check whether the code meets the predetermined complexity standard to identify possible mistyped or low-quality codes. These rules are implemented through algorithms to score or classify the MMSI codes. The specific classifications and measures are shown in Table 1: Table 1 MMSI code classification and measures to be taken

[0056] S3: Database comparison. Compare the verified MMSI code with the valid ship MMSI code in the database to confirm whether it belongs to a known valid ship. Establish and maintain a database containing the MMSI codes of all registered ships. Use efficient query algorithms (such as hash tables, index searches) for comparison operations. Record the comparison results, including whether the code is valid, the corresponding ship information, etc.

[0057] S4: Risk warning and interception. If the MMSI coding complexity is low or the database comparison results show that there is a risk of counterfeiting, the system will immediately start the risk warning and interception process. Design a risk assessment model to comprehensively judge the risk level based on the complexity verification results and database comparison results, such as Fig.10 , Fig.11 , Fig.12 If the risk level reaches the preset threshold, the early warning mechanism will be triggered to send a warning message to the maritime administration or relevant regulatory authorities. At the same time, according to the system configuration and regulatory requirements, measures such as suspending or blocking the ship's communications may be taken.

[0058] S5: User reporting and online correction. Provides a convenient reporting channel for ship owners or operators, allowing them to report MMSI code errors in a timely manner. Fig.13Set up an online reporting function in the system, and users can submit mis-entry reports through the web, mobile application or dedicated terminal. The report should include information such as the reason for the mis-entry and the correct MMSI code. Develop an online correction module to receive correction requests submitted by users. After verifying the user's identity and the accuracy of the correction information, update the MMSI code information in the database and restore the normal communication rights of the ship. Reference Fig.14 and Fig.15 , provides a management platform for maritime-related departments. At the same time, it records the log information of the correction operation for subsequent audit and tracking.

[0059] Special Identification and Prevention Mechanism: This embodiment designs a set of identification and prevention mechanisms specifically for MMSI codes that are easy to remember and easy to mistype. Different from general code verification, this mechanism will focus on analyzing and marking MMSI codes with obvious regularity (such as continuous repeated numbers, specific easy-to-remember sequences), and perform more stringent input verification and real-time monitoring on these codes. This special mechanism can more effectively identify potential counterfeiting risks and take preventive measures in advance.

[0060] Dynamic risk assessment and early warning system: This embodiment introduces a dynamic risk assessment model, combining historical behavior data, real-time location information, navigation trajectory and other multi-source data of the ship to conduct a comprehensive assessment of the use of MMSI codes. Once abnormal behavior is found (such as multiple wrong inputs in a short period of time, sudden changes in geographical location, etc.), the system will immediately trigger an early warning and automatically adjust the monitoring level of the code. This dynamic risk assessment and early warning system can more accurately capture counterfeiting behavior, respond in a timely manner and reduce risks.

[0061] Multi-factor verification and enhanced security: In addition to the traditional MMSI code verification, this embodiment also introduces a multi-factor verification mechanism, requiring the ship to provide additional verification information (ship certificate, ship feature photos, etc.) during the communication process. This additional information will be verified together with the MMSI code, greatly increasing the difficulty of counterfeiting. At the same time, the system will also strengthen security measures, such as encrypted communication, data backup and recovery, etc., to ensure the security and reliability of ship information.

[0062] User education and intelligent prompts: This embodiment focuses on the combination of user education and intelligent prompts. By providing detailed user guides and operation prompts, users can understand the correct use of MMSI codes and precautions, and reduce the occurrence of mis-entry and counterfeiting. At the same time, the system will also have an intelligent prompt function, which will automatically detect and prompt possible errors or risks when users enter MMSI codes, and guide users to perform correct operations. This combination of user education and intelligent prompts can significantly improve users' safety awareness and operation accuracy.

[0063] In summary, the beneficial effects of the embodiments of the present application are: 1. Specialized error-prone code intelligent recognition technology can deeply analyze the composition rules of MMSI codes, automatically identify codes with specific patterns (such as continuous repeated numbers, easy-to-remember sequences), and specially mark them and perform additional verification steps. This intelligent recognition method not only improves recognition efficiency, but also significantly reduces the risk of counterfeiting caused by incorrect code input.

[0064] 2. A multi-dimensional dynamic risk assessment model has been constructed. This model not only takes into account the historical behavior data and real-time location information of the ship, but also incorporates multiple factors such as navigation trajectory, navigation speed, and course changes, realizing comprehensive monitoring and real-time assessment of the ship's status. Through this system, the system can promptly detect abnormal behavior of the ship and issue early warnings based on the assessment results, providing management departments with more accurate and timely decision-making support. This multi-dimensional, dynamic risk assessment and early warning method has significant innovation and application value in ship safety management and emergency response.

[0065] 3. By providing detailed user guides and operation prompts, as well as intelligent input detection and error prompt functions, an organic combination of user education and intelligent prompts is achieved, which not only helps to improve users' safety awareness and operation accuracy, but also enhances the user-friendliness and ease of use of the system, allowing users to complete the input and verification process of ship identity information more conveniently and quickly.
