Description

Technical Field

[0001] This invention relates to the field of BeiDou terminal applications, and in particular to the field of BeiDou satellite short message terminals. Background Technology

[0002] The Beidou-2 satellite navigation system is a global satellite navigation system independently developed by China. In December 2012, the Beidou-2 system was completed and began providing services.

[0003] The BeiDou-3 satellite navigation system's space segment consists of 27 medium Earth orbit satellites, 5 geostationary orbit satellites, and 3 inclined geosynchronous orbit satellites, providing services globally. BeiDou-3 officially began providing global services on July 31, 2020. BeiDou-3 primarily provides basic navigation services, short message communication services (regional and global), satellite-based augmentation services, international search and rescue services, and precise point positioning services. The BeiDou-3 short message service has a capacity 10 times larger than BeiDou-2, while its transmission power is 10 times lower, resulting in significantly enhanced communication capabilities.

[0004] The operation of the BeiDou-3 short message system has changed from being provided by multiple companies for BeiDou-2 to being divided by industry. Each industry's relevant regulatory body is responsible for the operation and management of BeiDou-3 short message communication, while the respective industry authorities are responsible for issuing BeiDou cards and providing data push services. Considering system capacity and actual user needs, the BeiDou-3 short message system provides only one-way BeiDou communication for the large-scale data collection and uploading needs in the field. That is, the field terminal sends short message data to the BeiDou satellite via the L-band, the BeiDou satellite transmits it to the BeiDou ground station via the C-band, the BeiDou ground station pushes it to the corresponding industry operator via a dedicated ground line, and the industry operator then pushes it to the end users through the ground network.

[0005] During the use of the BeiDou-2 short message service, end users used the BeiDou command terminal as the receiving device to collect uploaded data from subordinate terminals. The BeiDou command terminal communicated with the user's professional business system via serial port. After upgrading to the BeiDou-3 short message system, due to the large amount of data being reported, only one-way communication is allowed. At this time, end users need to obtain short message data from field terminal users through the ground network via the corresponding BeiDou industry operator. This requires each user to perform secondary development according to the network interface service specifications provided by the industry operator. This will bring a large development workload and significant economic investment to many users, especially small and medium-sized users.

[0006] To address the aforementioned issues, the applicant proposes a method for implementing a virtual service system for the BeiDou-3 command system. Summary of the Invention

[0007] The purpose of this invention is to provide a method for implementing a virtual service system for the BeiDou-3 command system, so as to solve the problems in the prior art.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a method for implementing a BeiDou-3 command and control virtual service system, comprising the following steps:

[0009] Deploy and run the BeiDou-3 virtual command machine software service system on a standalone computer;

[0010] The software service system establishes a communication connection with the Beidou-3 industry short message operation and management center via a network interface using the TCP protocol, enabling login, heartbeat connection, and data reception functions.

[0011] The software service system connects to the user business system through the computer's physical serial port and forwards the received BeiDou-3 short message data to the user business system according to the preset serial port protocol.

[0012] The preset serial port protocol is consistent with the serial port protocol of the Beidou-2 command device, and its format is as follows:

[0013] $BDTXR,x,xxxxxxx,x,hhmm,c--c*hh <cr> <lf>,

[0014] The fields are defined in sequence as message type, user address, message format, sending time, and message content.

[0015] Optionally, the network interface communication function includes:

[0016] Based on the industry classification of the BeiDou-3 Industry Operation and Management Center, it adapts to different industry communication protocols;

[0017] Data exchange with operation and management centers in the land transportation, maritime transportation, meteorology, and energy industries is achieved through dynamic configuration.

[0018] Optionally, the physical serial port is an RS-232 standard serial port, and the software service system supports multiple operating system environments, including Windows and Linux systems.

[0019] Optionally, in the serial port protocol:

[0020] The information category field is defined as a normal communication type;

[0021] The user address field is a unique identifier for the sending terminal;

[0022] The message format field contains Chinese characters, codes, or a mixed transmission mode.

[0023] Optionally, the software service system implements the following data transmission process:

[0024] Receive short message data pushed by the BeiDou-3 Industry Operation and Management Center through the public ground network;

[0025] After parsing the data, it is forwarded to the user's business system via the physical serial port according to the preset protocol format;

[0026] Ensure that user business systems are compatible with BeiDou-3 short message service without secondary development.

[0027] Optionally, the software service system supports an automatic reconnection mechanism to re-establish the connection with the BeiDou-3 industry operation and management center after a network interruption or heartbeat timeout.

[0028] Optionally, the software service system verifies the received short message data, and the verification method includes:

[0029] Extract the characters between $ and * in the protocol, perform an XOR operation to generate a checksum;

[0030] Verify that the checksum matches the hexadecimal value at the end of the protocol to ensure data integrity.

[0031] Beneficial effects: 1. Seamless compatibility and rapid access

[0032] This invention replaces the original BeiDou-2 command and control hardware with a virtual service system software, and uses standard serial communication protocols (such as the $BDTXR protocol) to ensure that user business systems can seamlessly access the BeiDou-3 short message service without secondary development. Users only need to install the software on a separate computer and connect to the original system through a physical serial port, which greatly shortens the system upgrade time and achieves a smooth transition from BeiDou-2 to BeiDou-3.

[0033] 2. Significantly reduce user costs

[0034] This eliminates the need for secondary development of the interface between users and the BeiDou-3 industry operation and management center, saving small and medium-sized users significant software development costs and manpower. By replacing dedicated hardware with virtualization software, hardware procurement and maintenance costs are further reduced.

[0035] 3. Improved ease of operation and stability

[0036] The virtual service system encapsulates the complex communication logic with the BeiDou-3 industry operation and management center (such as TCP protocol communication, heartbeat connection, and data reception). Users do not need to worry about the reliability and stability of the underlying communication, which significantly simplifies the operation process and lowers the technical threshold.

[0037] 4. Multi-industry adaptability and scalability

[0038] The system supports flexible adaptation to different protocols in various industries (such as transportation, meteorology, and energy), and meets the needs of different user scenarios by being compatible with mainstream operating systems (Windows and Linux), thus possessing broad industry applicability and scalability.

[0039] 5. Enhance service capabilities and efficiency

[0040] Leveraging the advantages of BeiDou-3's short message service—large capacity and low power consumption—and combined with virtualization technology, users can efficiently receive massive amounts of data from field terminals, improving business processing efficiency. Simultaneously, the one-way communication mode optimizes the data transmission path, further ensuring service real-time performance.

[0041] 6. Market promotion value and economic benefits

[0042] This solution, characterized by low cost and low barriers to entry, addresses the core pain points of small and medium-sized users upgrading to the BeiDou-3 system, and has broad market application prospects. Its promotion will accelerate the popularization of BeiDou-3 short message service, inject new momentum into the development of the national satellite communication industry chain, and create significant economic and social benefits.

[0046] The preferred embodiments of the present invention are described below with reference to the accompanying drawings to make the technical content clearer and easier to understand. The present invention can be embodied in many different forms, and the scope of protection of the present invention is not limited to the embodiments mentioned herein.

[0047] In the accompanying drawings, components with the same structure are indicated by the same numerical designation, and components with similar structures or functions are indicated by similar numerical designations. The dimensions and thicknesses of each component shown in the drawings are arbitrary, and the present invention does not limit the dimensions and thicknesses of each component. To make the illustrations clearer, the thickness of some components has been appropriately exaggerated in the drawings.

[0048] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the specific structure and effects of the present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0049] like Figure 1 As shown, the process by which the BeiDou-2 short message system center user receives BeiDou short message data sent by the field terminal is as follows: the field BeiDou terminal sends the short message data to the BeiDou satellite via the L-band.

[0050] The BeiDou satellite transmits short message data to the BeiDou-2 ground station via the C-band. The BeiDou-2 ground station then transmits the short message data back to the BeiDou satellite via the C-band, and the BeiDou satellite then transmits the short message data to the BeiDou-2 command and control unit via the S-band.

[0051] The Beidou-2 command system then transmits the short message data received from the Beidou terminals in the field to the user's professional business system via serial port.

[0052] Furthermore, the short message data serial port protocol received by the Beidou-2 command terminal is a standard protocol format, defined as follows:

[0053] $BDTXR,x,xxxxxxx,x,hhmm,c--c*hh <cr> <lf>

[0054]

[0055] Furthermore, such as Figure 2 As shown, the process by which the BeiDou-3 short message system center user receives BeiDou short message data sent by the field terminal is as follows: the field BeiDou terminal sends the short message data to the BeiDou satellite via the L-band.

[0056] The BeiDou satellite transmits short message data to the BeiDou-3 ground station via the C-band. The BeiDou-3 ground station then pushes the short message data to the BeiDou-3 industry operation and management center of the corresponding industry via a dedicated line.

[0057] The BeiDou-3 Industry Operation and Management Center then pushes the short message data to the corresponding users via the public ground network.

[0058] Furthermore, such as Figure 3 As shown, the BeiDou-3 virtual command center software service system runs on a separate computer. The BeiDou-3 virtual command center software service system primarily provides communication services between the BeiDou-3 industry operation and management center and user professional application systems.

[0059] Furthermore, the BeiDou-3 virtual command terminal software service system communicates with the BeiDou-3 industry operation and management center via the TCP network protocol, and mainly performs the following functions:

[0060] 1) Login and Logout

[0061] 2) Heartbeat connection

[0062] 3) Data reception

[0063] Furthermore, the BeiDou-3 industry operation and management centers are divided into multiple industries, including land transportation, maritime transportation, railway, aviation, water conservancy, meteorology, and energy. The communication protocols of each BeiDou-3 industry operation and management center are slightly different. The BeiDou-3 virtual command machine software service system will be further adapted and developed according to the specific protocols of each industry to meet the communication service needs of the BeiDou-3 virtual command machine software service system and the BeiDou-3 industry operation and management centers.

[0064] Furthermore, the BeiDou-3 virtual command terminal software service system connects to the user business system through the computer's physical RS-232 serial port. Through the RS-232 serial port, the BeiDou short message data received by the BeiDou-3 virtual command terminal software service system is forwarded to the user business system.

[0065] The BeiDou-3 virtual command terminal software service system will be developed strictly in accordance with the BeiDou-2 command terminal serial port protocol to ensure seamless integration with users' professional business systems. The serial port protocol is consistent with the previous BeiDou-2 command terminal serial port protocol, as follows:

[0066] $BDTXR,x,xxxxxxx,x,hhmm,c--c*hh <cr> <lf>

[0067]

[0068] Furthermore, the BeiDou-3 virtual command system software service system will support typical WINDOWS and domestic LINUX systems, and can be adapted to various operating systems as needed in the future.

[0069] In summary, the present invention provides a method for implementing a BeiDou-3 command virtual service system. By installing and running the BeiDou-3 virtual command software service system on a computer, it replaces the original BeiDou-2 command system. Users can achieve communication services with the BeiDou-3 industry short message operation and management center without secondary development. Furthermore, users do not need to consider the complexity, reliability, and stability of communication services with the BeiDou-3 industry short message operation and management center, greatly improving the efficiency of users upgrading to and using the BeiDou-3 short message service system and significantly shortening the time for users to access the BeiDou-3 short message service system, enabling users to seamlessly upgrade and access the BeiDou-3 short message system.
