Structured data is highly organized and neatly formatted data, which is information that can be represented by a unified structure, such as numbers, symbols, etc., and is usually represented by a two-dimensional logical table of a database; unstructured data refers to all data other than structured data, such as images, videos, audio, etc. Information, without a fixed data structure and type, is difficult to manage, retrieve, and query in a standardized manner. The space-earth integrated network structure data is mainly composed of data elements such as nodes and edges. There are close link relationships between the data elements, the number of nodes and edges is large, the data volume is huge, and it is easy to represent the corresponding information with numbers and symbols.

[0033] Method embodiments

[0034] According to an embodiment of the present invention, a method for constructing a space-ground integrated network structure database is provided. Figure 1 It is the flowchart of the method for constructing a space-ground integrated network structure database in the embodiment of the present invention. As Figure 1 shown, the method for constructing a space-ground integrated network structure database according to an embodiment of the present invention specifically includes:

[0035] Step S101: Obtain the functional descriptions required for the database based on the composition and characteristics of the space-ground integrated network structure data;

[0036] The composition of the space-ground integrated network structure data includes three levels: nodes, links, and networks;

[0037] Among them, the characteristics of the space-ground integrated network structure data include the dynamics of node data and link data, the periodicity of link data, and the hierarchy and overlap of network data;

[0038] The functional descriptions required for the database include the function of uniformly storing and managing node data, the function of dynamically storing and managing link data, the function of hierarchically storing and managing network data, and the function of classifying and grading users;

[0039] Step S102: Design database tables through the functional descriptions to obtain a number of relational database tables;

[0040] The number of relational database tables includes node data tables, link data tables, and network data tables;

[0041] Among them, the node data tables include space-based node data tables, air-based node data tables, and ground-based node data tables;

[0042] The link data tables are based on the node data tables and include sending nodes, receiving nodes, and corresponding link information;

[0043] The network data tables are based on the link data tables;

[0044] Step S103: Build a space-ground integrated network structure database based on the number of relational database tables;

[0045] The method further includes:

[0046] Build a space-ground integrated network structure database management system using the MySQL Workbench tool based on the space-ground integrated network structure database, and perform corresponding operations on the space-ground integrated network structure data through the management system, specifically including:

[0047] Perform update, retrieval, and editing operations on the space-ground integrated network structure data through the management system;

[0048] Among them, the retrieval includes fuzzy retrieval based on keywords, exact retrieval based on satellite numbers, and range retrieval based on launch years;

[0049] The editing includes orbit data editing, ground station data editing, link editing, and network editing.

[0050] The following details the above technical solution of the embodiments of the present invention in combination with the specific situation of the construction method of the space-ground integrated network structure database of the embodiments of the present invention.

[0051] The embodiments of the present invention propose a space-ground integrated network structure data storage method based on a relational database, which is used to solve the problems of huge volume and difficult storage management of space-ground integrated network structure data. The method includes: analyzing the composition and characteristics of space-ground integrated network structure data, and describing the requirements and functions that its network structure information database should meet; designing a logical structure according to the analysis results, successively designing node, link, and network data tables, and constructing a space-ground integrated network structure database; developing a space-ground integrated network structure database management system through MySQL Workbench, and implementing functions such as orbit database management, orbit data search, orbit data editing, ground station data editing, link editing, and network editing. Through the embodiments of the present invention, efficient storage and management of complex network structure data can be realized, thereby effectively improving the work efficiency of management and maintenance personnel.

[0052] Current relational database management systems (RDBMS) mainly include MongoDB, SQLServer, MySQL, Oracle, etc. Among them, MySQL is widely used for its cross-platform nature, low usage cost, fast operation speed, security and reliability, etc., and is mainly used to provide data hosting services for various organizations, such as Facebook, Twitter, Yahoo, Wikipedia, YouTube, etc. MySQL can also be written in C and C++, and can be used either as a separate program in a client-server or as a library implanted into other software.

[0053] In terms of data storage, MySQL adopts a relational model, which consists of rows and columns to form a two-dimensional data table, facilitating users to read or query data. First, determine the format and content of the data in the fields, that is, the structure of the database table, and then store the data according to the table structure, so that the entire database table has high reliability and stability. In terms of data query, MySQL uses Structured Query Language (SQL) to implement operations such as database system updates, data management, and data query. In database design, an Entity Relationship Diagram (E-R) is usually used to reflect the relationships between tables in the database and the elements in the tables. A reasonable E-R diagram can effectively reduce data redundancy and improve the efficiency of the database.

[0054] Currently, users mainly use and manage the MySQL database through two methods: the command line and desktop software. MySQL Shell is a command-line tool that supports multiple languages and modes, allowing users unfamiliar with database scripts to operate on the database. MySQL Workbench is a visual database design software that provides a visual operation environment for users. Compared with MySQL Shell, users do not need to manually write and execute command statements, making it more convenient and faster to use.

[0055] A method for storing data of a space-earth integrated network structure based on a relational database proposed by an embodiment of the present invention includes the following steps:

[0056] S1. Analyze the composition and characteristics of the space-earth integrated network structure data, and describe the requirements and functions that the network structure information database should meet.

[0057] S2. Design the logical structure according to the analysis results, and design node, link, and network data tables in sequence to construct the space-earth integrated network structure database.

[0058] S3. Develop a management system for the space-earth integrated network structure database through MySQL Workbench, and implement functions such as orbital database management, orbital data search, orbital data editing, ground station data editing, link editing, and network editing.

[0059] Among them, the requirements and functions that the network structure information database should meet in step S1 are described as follows:

[0060] S11. Analyze the composition and characteristics of the space-earth integrated network structure data: The space-earth integrated network structure data mainly includes data at three levels: nodes, links, and networks.

[0061] Network nodes mainly include space-based nodes (spacecraft and their payloads), air-based nodes (near-space vehicles, etc.), land-based nodes (ground stations, etc.), and sea-based nodes (ships, etc.). Among them, the data of space-based nodes are mainly two-line orbital element (TLE) data of satellites, and the data of other nodes are mainly position parameters such as longitude, latitude, and elevation. Since satellites operate in their respective orbits, their state information such as position, speed, and operating attitude is constantly changing, and other movable nodes will also maneuver due to actual tasks. Therefore, the node data has obvious dynamics.

[0062] Network link data mainly consists of node data at both ends of the link, link attributes, and other information. It can be divided into inter-satellite links, satellite-ground links, etc. according to different end nodes, and can also be divided into various links such as TT&C and communication according to attributes such as transmission content. There may be dynamic information interactions between different nodes, such as between satellites and between satellites and ground stations. Therefore, link data has the characteristics of periodicity and dynamics.

[0063] Network data mainly consists of node data and link data. The space-ground integrated network has the characteristics of hierarchy and overlap, with situations such as multiple hierarchical networks coexisting, small networks existing in multiple large networks at the same time, and the backbone network connecting multiple subnets.

[0064] S12. Analyze the requirements and functions that the network structure information database should meet: Combining the above analysis of the composition and characteristics of the space-ground integrated network structure data, its network structure information database should meet the following three aspects of requirements: First, for the characteristics of a large number of network node types and large parameter differences, it should be able to uniformly store and manage node data; second, for the time-varying characteristics of links such as inter-satellite links and satellite-ground links, it should be able to dynamically store and manage link data; third, for the characteristics of network overlap and network layering in the space-ground integrated network, it should be able to hierarchically store and manage network data. As Figure 2 shown, in addition to conventional functions such as data management and data query, users should also be classified and hierarchically managed, and different types of users have corresponding permissions. The database administrator has the highest authority and can perform any operation on the database; the database maintenance personnel can perform operations such as data update, modification, and deletion; ordinary users can only query relevant data.

[0065] The steps to construct the space-ground integrated network structure database in step S2 are as follows:

[0066] S21. Design the node data table: The node data table mainly consists of a space-based node data table, an air-based node data table, and a ground-based node data table, and the structure is as Figure 3 shown. The space-based node data table mainly stores two-line satellite orbit data, including fields: target number, satellite name, first-line data, second-line data, satellite number, launch year, ephemeris number, TLE duration, number of orbits around the earth since launch, number of orbits around the earth per day, orbital inclination, right ascension of the ascending node, orbital eccentricity, argument of perigee, mean anomaly, etc. The E-R diagram is as Figure 4 shown. The air-based node data mainly stores aircraft position parameters and other information, including fields: target number, aircraft number, aircraft name, aircraft level, ground station type, longitude, latitude, altitude, etc. The E-R diagram is as Figure 5As shown in the figure. The ground node data table mainly stores the position parameters and other information of ground stations related to aerospace, such as measurement and control stations, satellite stations, navigation stations, data receiving stations, satellite management stations, etc. It contains fields: target number, ground station number, ground station name, ground station type, ground station level, longitude, latitude, altitude, etc. The E-R diagram is as Figure 6 shown. Since there are a large number of node types and quantities in the space-ground integrated network, to avoid the difficulty of data cognition and understanding for users caused by complex data, and to provide selectable display content for data visualization, it is necessary to classify and manage node information hierarchically. For example, according to the physical domain, it can be divided into satellites, aircraft, and ground stations, etc. Among them, satellite nodes can be divided into remote sensing, communication, navigation, etc. according to their functions, and can be divided into high-orbit, medium-orbit, and low-orbit according to the orbital altitude. The recursive tree method can generate a classification tree with infinite levels, and editing operations such as insertion, deletion, and creation can be performed on the classification tree; therefore, on the basis of the original data table, the recursive tree method is used to construct the classification trees of various nodes respectively. Its data table contains the following fields: target number, parent node number, node name, node number, etc. The E-R diagram is as Figure 7 shown. The specific steps to generate the classification tree by the recursive tree method are as follows:

[0067] Step 1: Find the node whose parent node is empty. This node is the root node;

[0068] Step 2: Find the next-level child nodes under this parent node;

[0069] Step 3: Traverse the found child nodes. If the node number is not empty, it means that the node is a leaf node. If it is empty, it is a branch node, and recursively find the node whose parent node is this child node;

[0070] Step 4: Recursively follow Step 3 level by level until all leaf nodes are traversed.

[0071] S22. Design the link data table: The link data table is constructed on the basis of the node data table, that is, a link data is composed of a sending node, a receiving node, and related link information. It contains fields: target number, link type, link number, link name, sending node type, sending node number, receiving node type, receiving node number, and other characteristic parameters, etc. The E-R diagram is as Figure 8 shown.

[0072] S23. Design the network data table: The network consists of several links, and network visualization is achieved by visualizing numerous links. Therefore, a network database table can be constructed based on the link data table. By classifying and grading the links, and then visualizing all links of a certain type or level, the effect of network visualization can be achieved. Combining the link data, a recursive tree method is used to construct a network classification tree. Its data table contains the following fields: target number, parent node number, node name, link number, etc. The E-R diagram is as shown in Figure 9 shown, and the specific method is the same as the steps for generating the node classification tree mentioned above.

[0073] In step S3, develop the space-earth integrated network structure database management system through MySQL Workbench, and the steps to implement various functions are as follows:

[0074] S31. Implement the orbit database management function: The orbit database management function mainly updates the satellite orbit data by batch importing two-line satellite orbit data stored in text format. During the batch import process, if the satellite does not exist in the database, this satellite is added to the database. If the satellite already exists, it is judged whether the TLE duration of the satellite in the currently imported text is later than that of the corresponding satellite in the database. If the TLE duration of the imported satellite is later than that of the satellite in the database, the satellite orbit data in the database is updated.

[0075] S32. Implement the orbit data search function: The orbit data search function supports fuzzy retrieval based on keywords, retrieval based on satellite numbers, and retrieval based on the launch year. The operation interface is as shown in Figure 10 shown. The fuzzy retrieval based on keywords provides fuzzy queries of satellite orbit data using keywords of satellite names. The retrieval based on satellite numbers can provide accurate retrievals based on satellite numbers. The retrieval based on the launch year can retrieve satellites launched within a specified year range.

[0076] S33. Implement the orbit data editing function: The operation interface of the orbit data editing function is as shown in Figure 11 shown, and it supports renaming, adding, and deleting satellite constellations, single satellites, and on-board sensors. After adding a constellation node under the node of the country type, multiple satellite nodes can be created under this constellation node through fuzzy retrieval based on keywords. After clicking on a satellite node, its corresponding information will be displayed in the left area, from which it can be seen that this information includes satellite name, satellite number, two-line orbit data, launch year, and six orbital elements, etc.

[0077] S34. Implement the ground station data editing function: The operation interface for ground station data editing is as shown in Figure 12As shown, it supports the import, deletion, and editing of ground station and near-space vehicle nodes. Ground-air node data can be imported in batches through text, and node numbers and names can be edited manually, and their longitude, latitude, altitude, and node types can be set.

[0078] S35. Implement the link editing function: The link editing operation interface is as Figure 13 shown, including three modules: link construction, link generation, and link editing. As Figure 13 can be seen, first, the corresponding node information can be obtained from the node database through fuzzy retrieval based on keywords. Then, check the sender and receiver that need to build the link. After that, traverse all senders and receivers to obtain a list of links to be imported into the database in batches, which is displayed in the list of the link generation module. Check the links that need to be imported into the database in the list, set the basic attributes of the links such as the maximum link distance, link category, level, etc., and then they can be imported into the database. Finally, in the link editing module, the links that need to be edited can be obtained through fuzzy retrieval based on keywords, and operations such as deleting the links can be performed.

[0079] S36. Implement the network editing function: The network editing function can use a classification tree to classify and manage different types of networks. For example, in Figure 14 , the satellite networks shown in the left network list are divided by country. If a new network needs to be added, right-click on the country node in the network list, select Add Node in the right-click menu, add a new network node under the country node through the pop-up dialog box, and then right-click on this network node, select Query and Insert Link in the right-click menu, and select the link to be placed under this network node through fuzzy retrieval based on keywords in the pop-up Query and Insert Link dialog box, as Figure 15 shown, and then click OK.
