Description

Technical Field

[0001] The present application relates to the field of space electric propulsion technology, and in particular to a method for establishing an ion electric propulsion engineering database and an analysis system thereof. Background Art

[0002] Electric propulsion is currently the most advanced space propulsion technology. Among them, ion electric propulsion is an aerospace propulsion system that uses electrostatic acceleration of a grid system to generate thrust. Ion electric propulsion products have been widely used in ultra-low orbit spacecraft, high-orbit communication satellites, and deep space exploration.

[0003] Currently, China's ion electric propulsion system is entering a new era of widespread application, with a significant increase in on-orbit and test data. Data management issues are gradually becoming apparent. First, test data is stored in a decentralized manner, with no dedicated database for product analysis, resulting in high data management costs. Second, data formats and storage locations are inconsistent, making programming code incompatible. Furthermore, when data volumes are large, data in formats such as CSV, XLS, and XLSX are slow to open. These issues have resulted in incompatible data processing programming codes, difficulty analyzing data from different sources, slow and inefficient data analysis, and impediments to mining massive amounts of ion electric propulsion data. Summary of the Invention

[0004] This application provides a method for establishing an ion electric propulsion engineering database and its analysis system. According to the characteristics of ion electric propulsion data and the current status of data management, the database and analysis system are constructed. The operation interface is convenient and can form a process.

[0005] In order to achieve the above-mentioned objectives, the present application provides a method for establishing an ion electric propulsion engineering database and its analysis system, comprising the following steps: Step 1: Use a relational database to establish a data storage layer, and design ion electric propulsion data tables according to the product development stage, ground test stage, and on-orbit conditions; Step 2: Use open source cross-platform development tools to establish a data management layer, and provide user operation pages, including designing data import functions, data query functions, and data editing functions; Step 3: Use the visualization tools in the database management and development tools to realize database backup and real-time data display; Step 4: Use numerical calculation software to connect to the database, establish a database analysis system, and calculate and analyze data results.

[0006] Furthermore, in step 1, the types of ion electric propulsion data tables include product geometry data, product rated electrical data, life test data, performance test data, historical failure data, special test data, on-orbit performance data, on-orbit environment data, time series trend analysis data, frequency domain analysis data, and dimensionality reduction clustering data.

[0010] Furthermore, in step 3, the Navicat for MySQL visualization tool is used to implement database backup and real-time data display.

[0011] Furthermore, in step 4, the Database Explorer module of the MATLAB software is connected to the database; when connected, the cross-platform application platform interface JDBC is used to connect to the database, the database and the required data table are selected from the directory list, and the SQL query statement is added using Manual to limit the data range.

[0012] Furthermore, in step 4, the database analysis system is based on the APP design function of MATLAB software to implement the C / S architecture, including the ion electric propulsion engineering database interface, MATLAB calculation analysis module and calculation result display module.

[0013] Furthermore, the MATLAB calculation and analysis module selects a callback function based on the input parameters and stores the final calculation results back into the MySQL database.

[0034] Step 2: Utilize an open-source, cross-platform GUI development tool to establish a data management layer, providing user interfaces. This includes designing data import, data query, and data editing functions. The data import function selects the appropriate data import format based on factors such as the ion propulsion mission, ion propulsion model, ion propulsion data source (product information / ground / on-orbit), and ion propulsion data type, and stores the data in the corresponding database. The data query function includes queryable items such as time period, product model, field name, and data source.

[0035] Step 3: Use the visualization tool in the database management and development tool (Navicat for MySQL) to realize database backup and real-time data display, such as Figure 2 As shown;

[0036] Step 4: Use numerical calculation software to connect with the database, establish a database analysis system, and calculate and analyze data results.

[0037] Specifically, connect the Database Explorer module of MATLAB software to the database, such as Figure 3 When accessing, use the cross-platform application platform interface JDBC to connect to the database, select the database and the required data table from the directory list, and use Manual to add SQL query statements to limit the data range, such as limiting the time period, variables, value range, etc.

[0038] Further, such as Figure 4 As shown, the database analysis system implements a client-server architecture based on the MATLAB software's app design functionality. It includes an ion electric propulsion engineering database interface, a MATLAB calculation and analysis module, and a calculation result display module.
