[0002] In addition to positioning, navigation, and timing, the BeiDou-3 navigation system also provides short message communication, which is a unique feature that distinguishes the BeiDou system from other global satellite navigation systems. On May 20, 2021, the China Satellite Navigation and Positioning Application Management Center and six industry sectors jointly launched the BeiDou-3 short message industry pilot application work. Since then, BeiDou-3 has been widely used in the transportation field. However, most BeiDou-3 applications are in one-way short message mode.

[0003] In July 2023, the BeiDou-3 regional short message two-way communication has been opened to the public in China and surrounding areas, which has brought new opportunities for the supervision and service model of maritime and ships. Under the situation of maritime actively promoting "big traffic control", the BeiDou-3 two-way short message can realize the traffic control and service data interaction between maritime and ships. Traffic control information, navigation notices (warnings), weather warnings and other information of maritime information services can be broadcast to ships; navigation plan information can be sent to designated ships in a timely manner to further improve the efficiency of ships entering and leaving the port. Positioning information, safety information, maritime reports and other information of small ships in the port can be sent to the maritime data center to improve the efficiency of maritime supervision; ship SOS distress information can be shared with the traffic control center and patrol ships to improve the emergency response and search and rescue efficiency of dangerous accidents and further improve people's safety.

[0004] This project mainly studies the interface protocol, technical specifications and data interface requirements of BeiDou-3 short message non-confidential authorization components; studies the application scenarios of maritime supervision and information services for small ships in ports; studies shared solutions that adapt to maritime "big traffic control"; establishes a technical solution for the application scenario model of maritime supervision and information services for small ships in ports; and conducts data interaction verification for refueling ships, construction ships and tourist ships in ports.

Obviously, the described embodiments are only 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.

[0020] It should be noted that all directional indications in the embodiments of the present application are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0021] In this application, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0022] In addition, in this application, descriptions such as "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features.

[0023] The maximum length of a single short message of BeiDou-3's regional short message communication service is 14,000 bits, which is approximately equivalent to 1,000 Chinese characters. The global short message communication service uses 14 MEO satellites to achieve global coverage of message communication services. The maximum length of a single short message is 560 bits, which is approximately equivalent to 40 Chinese characters. The terminal transmission power can be reduced to below 3W. The success rate of short message communication is also very high. According to the evaluation, the regional short message communication success rate is better than 99.6%, and the global short message communication success rate is better than 96.46%. At present, BeiDou-3's regional short message two-way communication has been opened to the public, but only in China and surrounding areas.

[0024] Embodiment 1

[0025] (1) Study the current status and prospects of maritime BeiDou-3 applications

[0026] Investigate and study the actual situation of BeiDou-3 application in maritime systems, analyze the application characteristics of each party; propose new models, functional requirements, and data interaction highlights of BeiDou-3 maritime supervision services.

[0027] Application status: Dongjiang Maritime is deploying the BeiDou-3 emergency command system and installing BeiDou-3 4G converged communication terminals on four patrol ships. The Dongjiang emergency command system can interconnect with tourist ships, construction ships, and Tianjin Port-registered ships through the BeiDou-3 command machine. In addition, the BeiDou-3 command machine interacts with the Blue Ocean Digital Service Center and shares data through the 4G patrol ship terminal. This research project has a good technical architecture, hardware foundation, and talent reserve.

[0028] (2) Research on the technical architecture of “Maritime + BeiDou-3” and collaborative management

[0029] Research and design technical solutions for the application of "Maritime + Beidou-3" that meet the requirements of the new digital-driven and innovative development pattern, and design information flows that are suitable for sharing and collaboration.

[0030] (3) Research on the functions and business logic model of maritime regulatory services for small ships in ports

[0031] After investigation, it was summarized that under the conditions of "large traffic control", the Beidou-3 short message should be used to provide regulatory service functions for refueling ships, construction ships and tourist ships in the port; and three ship regulatory service business logic models were designed.

[0032] (4) Experimental verification of the data exchange format of BeiDou-3 short messages

[0033] Based on the technical characteristics of BeiDou-3's short message application, such as communication level, single message capacity, and update frequency, a data exchange format for maritime regulatory services for refueling ships, construction ships, and tourist ships was designed.

[0034] The highest level of Beidou cards currently available for application is level 2. The longest voice that can be sent is 6 seconds, the single-message capacity is 131 Chinese characters, and the sending frequency is 60 seconds. On this basis, according to documents such as the "Interface Protocol for Beidou-3 Short Message Non-Secret Authorization Components", the "Technical Specifications for Beidou-3 Short Message Non-Secret Authorization Components", and the "General Data Interface Requirements for Beidou-3 Civilian Terminals", the communication protocol between the sharing platform and the APP in the on-board tripartite tablet is agreed upon, including functions such as SOS reporting, reporting safety, sending and receiving ordinary information, task dispatching, cruise planning, viewing meteorological information, and maritime traffic control information.

[0035] It must be sent after being encrypted in plaintext:

[0036] / ***

[0037] * The mode encoding type (message form): 1 - Chinese characters, 2 - code, 3 - mixed, 4 - compressed Chinese characters, 5 - compressed code

[0038] * Note: When using different encoding types, the requirements for the short message content are different, as follows

[0039] * In Chinese character form, the short message content must be Chinese characters. For example: Hello, content: "您好"

[0040] * In code form, the short message content must be HEX38 (hexadecimal string). For example: Hello, content: "C4FABAC3"

[0041] * In mixed form, the short message content must be HEX starting with A4. For example: Hello, content: "A4C4FABAC3"

[0042] * /

[0043] Generally, the mixed form is adopted, which has a relatively high confidentiality.

[0044] Based on these protocols, a basic message format is formulated, and the examples are as follows:

[0045] ① Ordinary message: MSG1: Hello; After encryption: 4D5347313AC4E3BAC3

[0046] ② SOS alarm: SOS: 39.072766,117.081108 Falling into the water for help; After encryption: 534F533A33392E3037323736362C3131372E303831313038C2E4CBAEC7F3BEC8

[0047] ③ Reporting safety: MSG2: Have arrived safely; After encryption: 4D5347323AD2D1C6BDB0B2B5BDB4EF

[0048] ④Task dispatch: MSG5: a_task initiator card number|b_task executor|c_task type|d_execution status|e_specific content|f_feedback information|g_2024-06-2009:22:10|h_a0c3c732-ebd5-4b73-8e7c-04c52dcb2d08;

[0049] After encryption: 4D5347353A615FC8CECEF1B7A2C6F0C8CBBFA8BAC57C625FC8CECEF1D6B4D0D0C8CB7C635FC8CECEF1C0E0D0CD7C645FD6B4D0D0D7B4CCAC7C655FBEDFCCE5C4DAC8DD 7C665FB7B4C0A1D0C5CFA27C675F323032342D30362D32302030393A32323A31307C685F 61306333633733322D656264352D346237332D386537632D303463353264636232643038

[0050] In some embodiments, the specific connection method and configuration steps when the Beidou command machine configures the firewall may vary due to different network environments, device models and security requirements. Therefore, in actual operation, adjustments and optimizations should be made according to specific circumstances.

[0051] In some embodiments, the Beidou control machine is directly connected to the front-end server via a serial port (such as RS232, RS422) or a network port.

[0052] In some embodiments, the physical connection is primarily accomplished by connecting an Ethernet cable at one end to a network interface card on a server and connecting the other end to an available port on a switch, ensuring that the connection is secure and not loose to achieve physical connectivity.

[0053] Embodiment 2

[0054] During the research process, the present invention adopts the following research methods including but not limited to:

[0055] (1) Survey methods: Through questionnaire surveys, interviews, observations and other means, the business application scenario requirements of maritime supervision of small ships in ports are collected, the basic data capabilities of maritime service information are collected, and the basic interactive format of ship data in ports for maritime supervision services is summarized.

[0056] (2) Experimental method: By using the Beidou-3 digital platform, verify the regulatory data communication of at least three groups of in-port ships through the Beidou-3 command machine. By controlling the format and content variables of the short message, obtain the basic data interaction format that meets the regulatory service requirements and complies with the Beidou-3 authorized component interface protocol, technical specifications, and data interface requirements.

[0057] (3) Empirical method: Verify the interface between the Beidou-3 digital platform and the maritime bureau data center through actual examples, and share the terminals of shipping companies to verify the maritime regulatory services and collaborative regulatory efficiency.

[0058] (4) Expert seminar: During the implementation of this project, some experts in the industry will also be invited to hold expert seminars irregularly to offer suggestions for the research of this project.

[0059] The Beidou short message data interaction format is as follows:

[0060] I. Introduction

[0061] Combined with the technical characteristics such as the communication level, single-message capacity, and update frequency of the short message application of Beidou-3, design the data interaction format for refueling ships, construction ships, and tourist ships in maritime regulatory services.

[0062] Currently, the highest level of Beidou card that can be applied for is level 2. The longest voice that can be sent is 6s, the single-message capacity is 131 Chinese characters, and the sending frequency is 60s. On this basis, according to documents such as the "Beidou-3 Short Message Non-Secret Authorized Component Interface Protocol", "Beidou-3 Short Message Non-Secret Authorized Component Technical Specifications", and "Beidou-3 Civilian Terminal General Data Interface Requirements", agree on the communication protocol between the shared platform and the APP in the on-board tripartite tablet, including functions such as SOS reporting, reporting safety, real-time information sending and receiving, task dispatching, and cruise plan.

[0063] II. Data Encryption Protocol

[0064] It can only be sent after encrypting the plaintext:

[0065] / ***

[0066] * mode encoding type (message form) 1 - Chinese characters, 2 - code, 3 - mixed, 4 - compressed Chinese characters, 5 - compressed code

[0067] * Note: When using different encoding types, the requirements for the short message content are different, as follows

[0068] * In Chinese character form, the short message content must be Chinese characters. For example: Hello, content: "您好"

[0069] * In code form, the short message content must be HEX38 (hexadecimal string). For example: Hello, content: "C4FABAC3"

[0070] *Mixed format, the short message content must be HEX starting with A4, for example: Hello, content: "A4C4FABAC3"* /

[0071] Generally, a mixed form is adopted, which has higher confidentiality.

[0072] According to these protocols, basic message formats are developed, examples are as follows:

[0073] 1. SOS reporting: SOS: latitude, longitude, text content (text content is limited to no more than 100 Chinese characters) 2. Report safety: MSG2: latitude, longitude, text content (text content is limited to no more than 100 Chinese characters) 3. Real-time information sending and receiving: latitude, longitude, text content (text content is limited to no more than 100 Chinese characters)

[0083] Maritime report: MSG5: Name|Telephone|Unit|Time|Event type|Latitude|Longitude|Remarks

[0084]

[0085] Travel plan: MSG5: Chinese ship name | English ship name | Identification number | Yacht movement | Planned time | Jurisdiction | Starting point | Activity waters | Emergency phone number | Submitter | Submission time | Start time | End time

[0086] 3. Data Interaction Process

[0087] The program code loaded in each terminal edits the information filled in by the user into a character string according to the data format agreed upon above, encrypts the data into a hexadecimal character string according to the Beidou data protocol, sends it to the Beidou communication satellite through the communication protocol, and the satellite sends it to the information service platform; after receiving the information, the information service platform parses the received hexadecimal character string according to the Beidou data protocol, and restores it to a text character string in the agreed data format. First, a prompt box is popped up (the level of the prompt box is different for different keywords, for example: if the keyword is SOS, the prompt box is red and warns, and clicking the prompt box can quickly locate the user on the map according to the longitude and latitude in the content, etc.); second, the delimiter in the data format is used to divide the content into the contents of each field and display it in the interface; third, an automatic reply is sent to the sender.

[0088] After receiving the information, the information service platform needs to display and prompt, and further process it. For example, the maritime report information received needs to be further verified. If it is confirmed to be true, it needs to be reported to the relevant department; the yacht's prohibited area is circled according to the navigation plan, and a warning is issued if it goes out of the circle.

[0089] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", "some examples", etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification.

[0090] In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0091] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
