Description

Technical Field

[0001] The present application relates to the field of aerospace technology, and in particular to a system architecture design for integrated satellite data tracing. Background Art

[0002] For a long time, the research and development units have been facing the problem of "willing but insufficient" in effectively and fully utilizing various data assets. Extracting and processing the unique information rules related to equipment from the research and development test data or the on-orbit operation data can better predict and maintain the health status of on-orbit satellites, optimize the design of ground test plans more timely, and improve the quality of equipment. This project proposes to establish a "satellite data comprehensive traceability system" in the on-orbit center. First, the scope of data collection is clarified. In comparison, since the project was established, most of the life cycle of satellite equipment occurs in the on-orbit operation stage; the data link with the satellite measurement and operation control center cannot be connected to the production network; more importantly, the essential feature of on-orbit data is that it occurs under comprehensive working conditions, and the physical fields are naturally coupled, which is different from the exclusive typical working condition data on the ground. Ground data has reference value for on-orbit data, and on-orbit data has guiding significance for ground data. The core value of establishing a data support system in the operation and control center is to use its advantageous position to feed back the shortcomings of ground tests, optimize and improve the test plan as a whole, and ultimately focus on improving the quality of equipment leaving the factory, especially for batch and mass production models.

[0003] Through engineering practices such as platformization, spectrumization, and software productization, model projects have gradually radiated to other ongoing and follow-up projects. As the commonality foundation expands, the demand and potential value of comprehensive and unified data management and application will also increase. The construction of a comprehensive satellite data traceability system will fully integrate on-orbit and ground data: the test method basis within the model will be formed on-orbit and integrated on-orbit maintenance; special case problems between models will be generalized and advanced, fully ensuring the quality of equipment development and on-orbit safety.

[0004] The satellite data comprehensive traceability system needs to trace the status data of multiple satellites in orbit at the same time, including satellite telemetry and control data, single-machine operating condition data, single-machine telemetry and control data and other subsystem-related data. These data need to be combined with ground test data and traced, so that auxiliary support personnel can carry out operation and control support work more efficiently, and form a complete technical closed loop for satellite data from source to method, and from method to result.

[0005] (1) Satellite data tracing models require a large amount of data support

[0006] The tracing of satellite in-orbit data and ground data often involves multiple satellites. The aspects considered when tracing the data are often not limited to the properties of the satellite, but are also closely related to the environment of outer space. Therefore, a large amount of effective data support is required to derive a stable model.

[0007] (2) Satellite operation and control data tracing system needs to be changed

[0008] In the past, the operation and control support system often handled the differences between ground and on-orbit data through experience and manual comparison, which wasted unnecessary resources, and the application of data was not complete enough, making it impossible to accurately extract effective information.

[0009] (3) The current satellite operation and control support system is not yet complete

[0010] The existing operation and control support system is not comprehensive enough in assessing the status of satellites throughout their life cycle. The data analysis of the ground test system is too narrow and the ground test plan is fixed. It is necessary to use the data traceability system to compare and analyze the ground test data with the in-orbit satellite data to provide iterative guidance for satellite testing.

[0011] Therefore, a new system structure for comprehensive satellite data tracing is needed to realize big data storage, comparison, analysis and tracing to optimize and improve the satellite processing and manufacturing technology. Summary of the invention

[0012] In view of this, the present invention provides a system architecture design for comprehensive satellite data tracing. Aiming at the difference between on-orbit satellite operation data and ground test data, a traceability relationship is established between the two. After big data comparison and analysis, the use value of on-orbit status data is improved, and big data storage, comparison, analysis and tracing are realized to optimize and improve the satellite's processing and manufacturing technology.

[0013] The present invention provides a system architecture design for satellite data comprehensive tracing, the system architecture comprising:

[0014] The integrated space-ground satellite data tracing system establishes the traceability relationship between on-orbit satellite activity data and ground experiment data;

[0027] Further, the on-orbit data module is an on-orbit status data extraction module;

[0028] The on-orbit status data extraction module transmits the real-time telemetry data of the on-orbit satellite back to the ground or communicates with the ground.

[0029] Furthermore, the satellite data real-time tracing system performs core big data analysis of a human-computer interaction interface based on a big data database formed by the ground data and the on-orbit data.

[0030] Furthermore, the satellite data real-time tracing subsystem cross-compares the ground data with the on-orbit data based on an artificial intelligence program, establishes a difference threshold, and uses the data outside the threshold as the difference value; and uses the data within the threshold as the same or similar value to form a reference for judging the health status of the on-orbit satellite.

[0031] Furthermore, the on-orbit satellite accumulates relevant values ​​of the judgment reference to obtain the tendency of various problems to occur in the actual on-orbit operating environment to guide ground experiments and optimize and improve production and design as a whole.

[0032] Furthermore, the satellite data real-time tracing subsystem realizes the data traceability of the entire declaration cycle of the satellite from design to on-orbit operation;

[0033] The satellite data real-time tracing subsystem also enables cross-comparison of process data within the satellite life cycle, can cite associations and form a complete technical closed loop to improve the optimization experimental efficiency and factory quality of mass-produced satellites.

[0043] Based on this, the embodiment of this specification proposes a system architecture design scheme for comprehensive tracing of satellite data: Figure 1 shown.

[0044] The system architecture of the present invention is also called a space-ground integrated satellite data comprehensive traceability system. The system aims at the objective problem that there are differences between the on-orbit satellite operation data and the ground test data, establishes a traceability relationship between the two, extracts the status data of the on-orbit satellite, and collects ground data at the same time, including a process design data extraction module, a manufacturing execution data extraction module, and a ground test status data extraction module, to form a traceability relationship and improve the use value of the on-orbit status data.

[0045] The satellite development and production process data extraction subsystem is responsible for the data collection, extraction, classification and aggregation of a series of processes including satellite pre-research, project establishment, design, testing and production. This subsystem imports the data obtained in the above stages into the database based on the working conditions for subsequent analysis and tracing. Its system modules include ground data and on-orbit data:

[0046] Ground data extraction includes process design data extraction, which collects statistics on data from the satellite design phase; manufacturing execution data extraction, which collects and stores relevant test parameters from the satellite manufacturing phase; and ground test status data extraction, which collects and stores the parameters of each unit and ground measurement data from the satellite test phase.

[0047] On-orbit data refers to the extraction of on-orbit status data, which is usually the telemetry data and digital transmission data transmitted back to the ground by the on-orbit satellite in real time. The satellite data real-time traceability subsystem is centered on a big data analysis human-computer interaction interface based on the above database. It comprehensively compares and interprets all data classified according to working conditions. It cross-compares the ground experimental data with the on-orbit operation data through a significance analysis program, and establishes a comparison threshold. If the result is greater than the threshold, there is no significant difference. The ground experimental data under the same or similar working conditions is used to form a reference for the interpretation of the health status of the on-orbit satellite. Through the accumulated data of the on-orbit satellite, the working conditions and working hours where various problems tend to occur in the actual on-orbit environment are obtained, guiding the overall optimization and improvement of ground experiments and production / design processes. The whole life cycle data from design to on-orbit operation can be traced, and the data of each process in the satellite life cycle can be cross-compared and cited with each other to form a complete technical closed loop, so as to improve the optimization, experimental efficiency and factory quality of batch and mass-produced satellites.

[0048] The subsystems of the technical solution of the present invention are:

[0049] (1) Ground data extraction subsystem architecture: collect statistics on satellite design phase data, manufacturing execution data, parameters of each unit in the satellite testing phase, and ground measurement data;

[0050] (2) Design of on-orbit status data extraction technology: With a big data analysis human-computer interaction interface based on a database as the core, all data classified according to working conditions are comprehensively compared and interpreted;

[0051] (3) Technical implementation design of satellite data comprehensive traceability system: Through artificial intelligence programs, ground test data and on-orbit operation data are cross-compared. Ground test data under the same or similar working conditions are used to form a reference for judging the health status of on-orbit satellites. Through the accumulated data of on-orbit satellites, the working conditions and working hours where various problems tend to occur in the actual on-orbit environment are obtained, guiding the overall optimization and improvement of ground experiments and production / design processes.

[0052] Each embodiment in this specification is described in a progressive manner, and the same or similar parts between the embodiments can be referred to each other, and each embodiment focuses on the differences from other embodiments. In particular, for the product embodiment described later, since it corresponds to the method, the description is relatively simple, and the relevant parts can be referred to the partial description of the system embodiment.
