[0020] The principles and spirit of the present application will be described below with reference to several exemplary embodiments. It should be understood that the purpose of providing these embodiments is to make the principles and spirit of the present application clearer and more thorough, so that those skilled in the art can better understand and implement the principles and spirit of the present application. The exemplary embodiments provided herein are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments herein, all other embodiments obtained by ordinary technicians of the art without creative work are within the scope of protection of this application.

[0021] With the development of aerospace technology, the number of spacecraft in orbit has increased dramatically, and a series of space environmental disasters such as space debris collisions, particle radiation failures, and atmospheric orbital decay often occur. At present, some new personnel in space environmental risk assurance usually only learn through some traditional textbooks or follow-up learning at work, so that trainees cannot receive thorough and complete training during the actual learning period, and there are many hidden dangers after entering the job. In order to enable relevant personnel to quickly acquire space environment assurance capabilities, the present application provides a space environment training system based on historical data, a training method based on the space environment training system, an electronic device, a computer-readable storage medium, and a computer program product. The system is designed to improve the analysis and emergency response capabilities of relevant personnel for solar storm risks, and ensure that they can respond quickly and accurately when a real solar storm occurs.

[0022] The following first introduces the space environment training system based on historical data provided by the implementation of this application.

[0023] Figure 1FIG. 1 is a structural block diagram of a space environment training system based on historical data in an embodiment of the present application. Figure 1 As shown, the space environment training system 10 based on historical data in an embodiment of the present application may include a space environment alarm event database 101, a training scenario setting module 102, a training data generation module 103, a mission risk determination module 104, a training scenario presentation module 105 and a report production module 106.

[0024] The space environment alarm event database 101 stores historical space environment monitoring data, space environment event types, space environment event alarm levels, and space environment event durations corresponding to multiple space environment alarm events. Among them, multiple space environment alarm events may include space environment alarm events of multiple different levels. For example, they may include solar proton events, solar flare events, geomagnetic storm events, high-energy electron storm events, ionospheric storm events, and ionospheric sudden disturbance events. It should be noted that the event types of space environment alarm events stored in the space environment alarm event database 101 can be flexibly adjusted according to actual conditions, and this application does not limit this.

[0025] Furthermore, each type of space environment alarm event can be divided into multiple alarm levels, that is, each type of space environment alarm event can include space environment alarm events of multiple alarm levels of that type. For example, in some examples, for example, according to the severity from low to high, it can be divided into three alarm levels, yellow alarm level, orange alarm level and red alarm level. Taking solar proton events as an example, for example, the space environment alarm event database 101 can store solar proton events of yellow alarm level, solar proton events of orange alarm level and solar proton events of red alarm level.

[0026] Each space environment alarm event may have corresponding historical space environment monitoring data, event type, alarm level and event duration. Among them, the historical space environment monitoring data of each space environment alarm event, that is, the space environment monitoring data of each space environment alarm event in the historical time period, can be collected in advance. For example, according to the space environment risk assurance training requirements, it can be obtained by collecting the monitoring data of space equipment (such as satellites) in the historical time period, the monitoring data of ground equipment (such as ground observation equipment) in the historical time period and / or international shared data. For example, the historical space environment monitoring data of multiple space environment alarm events may include solar activity data, interplanetary space data, magnetosphere data, ionosphere data, middle and upper atmosphere data and / or space target orbit data. After collecting the historical space environment monitoring data of each space environment alarm event, the collected data can be stored in the space environment alarm event database 101 for standby after data cleaning. Exemplarily, data cleaning may include operations such as processing missing values ​​and removing outliers.

[0027] The training scenario setting module 102 may be used to set the training mission scenario and the space environment scenario of the current training in response to the received training mission scenario and the space environment scenario imagined by the instructor.

[0028] Specifically, during training, the training task scenario and the space environment scenario can be flexibly set according to the needs of the user (such as the instructor). For example, the instructor can imagine the training task scenario and the space environment scenario, and then input the imagined scenario into the space environment training system 10. The space environment training system 10 can support selection button input, input box input, and voice input, etc. The training scenario setting module 102 in the space environment training system 10 can be used to set the training task scenario and the space environment scenario of the current training in response to the received training task scenario and space environment scenario imagined by the instructor. That is, the training task scenario imagined by the instructor is set as the training task scenario of the current training, and the space environment scenario imagined by the instructor is set as the space environment scene of the current training.

[0029] The training data generation module 103 can be used to query the historical space environment monitoring data of the target space environment alarm event corresponding to the set space environment scene from the multiple space environment alarm events stored in the space environment alarm event database 101, and use it as the target space environment monitoring data for space environment training.

[0030] For example, if the space environment scenario imagined by the instructor is a solar proton event with an orange alert level, the historical space environment monitoring data of solar proton events with an orange alert level will be queried from the space environment alarm event database 101 and used as the target space environment monitoring data for this space environment training.

[0031] The training data generation module 103 can also be used to obtain space environment current report data reflecting the impact of solar activity on the near-Earth space environment based on target space environment monitoring data and a space environment model.

[0032] Specifically, after obtaining the target space environment monitoring data of this space environment training, the target space environment monitoring data can be input into the corresponding space environment model to obtain the space environment current report data reflecting the influence of solar activity on the near-Earth space environment. Among them, the space environment monitoring data can be understood as data detected by space equipment and / or ground equipment. The space environment current report data is the spatial distribution data calculated based on the monitoring data and the space environment model. Exemplarily, the space environment model includes but is not limited to the bow shock model, the magnetopause model, the geomagnetic field model, the earth radiation belt model, the ionosphere model and / or the atmosphere model. The space environment current report data includes but is not limited to the shock wave position, the magnetopause position, the magnetic field line distribution, the radiation belt electron distribution, the radiation belt proton distribution, the ionosphere electron density distribution and / or the atmospheric density distribution. Taking the solar proton event as an example, for example, the target space environment monitoring data can be input into the earth radiation belt model (such as the proton model AP8 / AP9), and the proton flux distribution at the satellite orbit altitude is calculated, and then the model calculation results are corrected according to the GEO orbit proton monitoring data, and finally the satellite orbit proton flux current report data is obtained.

[0033] The training data generation module 103 can also be used to obtain space environment forecast data for future time periods based on target space environment monitoring data, space environment current report data and neural network model. Specifically, for example, the target space environment monitoring data and space environment current report data can be input into the trained neural network model to predict the space environment forecast data for future time periods. Exemplarily, the space environment forecast data includes but is not limited to solar activity data, solar wind data, geomagnetic index, particle flux, ionospheric electron density, and atmospheric density data for future time periods.

[0034] The mission risk determination module 104 can be used to calculate the space environment risk information of the current training scenario based on the target equipment data, the target space environment monitoring data, the space environment current report data and the space environment forecast data. The target equipment data may include the target satellite and radar equipment data used in the training. In some examples, the space environment risk information is the effect value of the space training scenario on the target equipment and its effect risk index. Among them, the effect risk includes but is not limited to: single particle upset effect risk, deep charge and discharge effect risk, surface charge and discharge effect risk, total dose effect risk, displacement damage effect risk, atomic oxygen erosion effect risk, orbital attenuation effect risk, signal transmission affected by the ionosphere effect risk and debris collision effect risk. The larger the effect risk index, the higher the alarm level.

[0035] For example, for the single particle upset effect, the number of single particle upsets of multiple sensitive devices in the target satellite can be calculated based on the proton flux of the orbit of the target satellite, the three-dimensional shielding data of the target satellite, and the parameters of the single particle upset sensitive device. According to the calculated value of the single particle upset number, the corresponding single particle risk index is determined. For example, when the number of single particle upsets is in the range of [0.01, 0.1), the corresponding single particle risk index is 1, indicating low risk. Among them, [0.01, 0.1) means that this interval starts from 0.01 but does not include 0.1. When the number of single particle upsets is in [0.1, 1), the corresponding single particle risk index is 2, indicating medium risk. When the number of single particle upsets is in [1, 10), the corresponding single particle risk index is 3, indicating high risk. When the number of single particle upsets is greater than or equal to 10, the corresponding single particle risk index is 4, indicating extremely high risk.

[0036] The training scenario presentation module 105 can be used to generate a three-dimensional dynamic scene according to the set training mission scene and space environment scene; and present the training data through the three-dimensional dynamic scene and data change chart, so that the trainee can revise the risk assessment report based on the presented training data. The training data includes but is not limited to the orbital data of the target satellite, the target space environment monitoring data, the space environment current report data and the space environment forecast data.

[0037] The three-dimensional dynamic scene can present the real-time relative positions of the sun, earth, moon and target satellite, and present a realistic solar storm scene, so that students can experience the impact of solar storms on near-Earth space and related tasks in person, and enhance the students' training experience. The data change chart can present dynamic training data and display the changes in the solar-terrestrial space environment, which is convenient for students to view and query. Students can revise the subsequent risk assessment report based on the training data presented by the three-dimensional dynamic scene and data change chart.

[0038] The report making module 106 can be used to generate a preliminary risk assessment report for the current training scenario based on the training data and the space environment risk information, receive revision information input by the trainees during the training process, and revise the preliminary risk assessment report based on the revision information to obtain the final risk assessment report for the current training scenario.

[0039] Students can make risk assessment reports based on the current situation of the space training scene and the need to make risk assessment reports. In some specific examples, when the system interface pops up the space environment alarm event information, students are required to make the corresponding risk assessment report of the space environment alarm event in a timely manner. Students need to select the report template, set the time and the corresponding task information, and then click to generate the risk assessment report. When making the risk assessment report, in order to ensure the timeliness of the product, the space environment training system supports the automatic generation of the first version of the risk assessment report based on the template, training data, space environment risk information and time selected by the students. Students can conduct risk analysis based on monitoring data, current report data and forecast data combined with their own experience. The space environment training system supports students to edit and modify the first version of the risk assessment report using the re-analysis results of the training data presented by the space environment training system to obtain the final risk assessment report of the current training scene. The space environment training system provided in this application can train students to analyze and deal with solar storm risks and ensure that they can respond quickly and accurately when a real solar storm occurs.

[0040] Traditional training methods rely on textbooks or learning from a class, and lack simulation of real scenes. The space environment training system based on historical data provided by the embodiment of the present application can simulate real space environment scenes by utilizing historical space environment alarm event data (including monitoring data, space environment event types, space environment event alarm levels, and space environment event durations), making training closer to actual mission requirements and solving the problems of single scenes and insufficient learning in traditional training.

[0041] On the other hand, traditional training methods are usually unable to provide dynamic risk analysis and emergency response training. The space environment training system based on historical data provided by the embodiment of the present application can generate real-time space environment current report data and forecast data through the training data generation module and the mission risk determination module, and calculate risk information in combination with equipment data. Trainees can revise risk assessment reports based on these data, thereby improving their ability to analyze and respond to space environment risks such as solar storms. Through real-time data and risk calculation, trainees can conduct actual combat exercises in a virtual environment, making up for the shortcomings of traditional training.

[0042] On the other hand, traditional training usually lacks multi-dimensional data support, and it is difficult for trainees to fully grasp the complexity of space environment risks. The space environment training system based on historical data provided by the embodiment of the present application generates training data including target equipment data, historical monitoring data, current report data and forecast data, providing comprehensive data support for trainees. Trainees can conduct risk assessment and decision-making training based on these data, and integrate multiple data to help trainees understand risks more comprehensively.

[0043] On the other hand, traditional training methods usually lack dynamic adjustment capabilities, and the learning effect of students is difficult to quantify. Students may not be able to effectively deal with risks in actual work due to insufficient training. The space environment training system based on historical data provided by the embodiment of the present application, through the training scene setting module and the training scene presentation module, the system can dynamically generate three-dimensional dynamic scenes and data change charts according to the settings of the instructor, and present the training data in real time. Students can revise risk assessment reports based on this information, and the system can also dynamically adjust the training difficulty according to the performance of the students. Through dynamic scenes and real-time feedback, training is made more flexible and efficient. In addition, by simulating real space environment alarm events and providing comprehensive training data, the system can help students better identify and respond to risks in actual tasks, thereby reducing the potential for accidents caused by lack of experience or insufficient training.

[0044] On the other hand, traditional training methods usually lack practical training for risk assessment reports, and trainees may encounter hidden dangers in actual work due to lack of experience. The space environment training system based on historical data provided by the embodiment of the present application can generate a preliminary version of the risk assessment report through a report making module, and generate a final report based on the trainee's revised information. This process not only helps trainees master the risk assessment method, but also improves the accuracy and practicality of the report, helping trainees to better deal with risks in actual tasks.

[0045] In addition, by using the space environment training system based on historical data provided in the embodiment of the present application, instructors can flexibly set training task scenarios and space environment scenarios through the system, and generate training content by combining historical data and real-time data. This supports instructors to flexibly customize training content according to actual conditions and supports targeted personalized training for different students.

[0046] For ease of understanding, the following are examples of risk assessment reports and training scenarios.

[0047] In some specific embodiments, optionally, for example, the initial version of the risk assessment report can present the following content for the current training scenario: space environment event information, causes of space environment alarm events, development trends of space environment alarm events, risks to the mission, and emergency response recommendations.

[0048] Taking the solar proton event in the current training scenario as an example, the initial risk assessment report can show that the current space environment alarm event is a solar proton event at the orange alert level, the causes of the solar proton event at the orange alert level, and the development trend of the solar proton event at the orange alert level, that is, whether the solar proton event will worsen, alleviate, remain unchanged, or show any changes in the future. The initial risk assessment report can also present the risks and emergency response suggestions caused by the solar proton event at the orange alert level to the target satellite.

[0049] The initial risk assessment report can provide a certain reference for trainees. In addition, trainees can conduct risk analysis based on the training data presented by the space environment training system and their own experience, and input revision information for at least one of the above contents in the initial risk assessment report into the system. For example, edit and modify the alarm level of the space environment alarm event, the cause of the space environment alarm event, the development trend of the space environment alarm event, the risk caused to the mission and / or emergency response suggestions, etc.

[0050] Accordingly, after receiving the revision information input by the trainees, the report preparation module 106 can be specifically used to revise at least one of the space environment risk information, the causes of space environment alarm events, the development trend of space environment alarm events, the risks caused to the mission and the emergency response recommendations in the initial risk assessment report based on the revision information to obtain a revised final risk assessment report.

[0051] In some specific embodiments, the training mission scenario may optionally include mission type, mission period, mission phase, and security element information. Security element information may include equipment information such as satellites and radars, such as satellite name, satellite orbit parameters, shielding thickness of satellite internal devices, sensitive device parameters, etc. The target time may be any time, which is not limited in this application. The space environment scenario may include space environment event type, space environment event alarm level, and space environment event duration.

[0052] For example, in some specific examples, for example, the instructor selects a target satellite, sets the mission period from April 1, 2030 to April 10, 2030, the mission phase is the on-orbit operation phase, the orange alert level solar proton event, the solar proton event start time is 12:00 on April 3, 2030, and the solar proton event lasts for 18 hours, so as to realize the assumption of the training mission scenario and the space environment. The training scenario setting module 102 can be used to respond to the received training mission scenario and space environment scenario assumed by the instructor, and set the training mission scenario and space environment scenario of the current training.

[0053] The training scene presentation module 105 can be specifically used to construct a three-dimensional dynamic scene of the sun, the earth, the moon and the target equipment according to the relative position information of the sun, the earth, the moon and the target equipment at the target time, and add a space environment alarm event screen corresponding to the space environment event type, the space environment event alarm level and the space environment event duration in the three-dimensional dynamic scene. The three-dimensional dynamic scene allows trainees to experience the impact of solar storms on near-Earth space and related tasks in an immersive way, thereby enhancing the trainees' training experience.

[0054] Considering that the learning progress of different students may be different, for example, some students may quickly master the ability to deal with some event types of space environment alarm events. At this time, training these students on these event types of space environment alarm events will have little effect on improving the students' abilities. Moreover, emergencies may occur in the space environment, and it is necessary to improve the students' ability to deal with complex space environments and emergencies. Therefore, in some embodiments, the space environment training system supports instructors to temporarily adjust the training scenarios and replace the original training data according to training needs or student performance. This flexibility allows training to better adapt to the ability levels and learning progress of different students. In addition, students can face more diverse scenarios during training, thereby improving their ability to deal with complex and unexpected situations.

[0055] Figure 2 Another structural block diagram of the space environment training system based on historical data in the embodiment of the present application. Figure 2 As shown, according to some embodiments of the present application, optionally, the space environment training system 10 may further include a temporary guidance module 107, which is used to receive the space environment event type, space environment event alarm level and space environment event duration of the space environment temporary guidance scenario set by the instructor. For example, taking the solar proton event as an example, for example, the space environment scenario originally set by the instructor is an orange alert level solar proton event, the solar proton event starts at 12:00 on April 3, 2030, and the solar proton event lasts for 18 hours. Through temporary guidance, for example, a yellow alert level solar proton event can be added, the solar proton event starts at 9:00 on April 8, 2030, and the solar proton event lasts for 10 hours.

[0056] Accordingly, the training data generation module 103 can also be used to query the historical space environment monitoring data of the space environment alarm event corresponding to the space environment temporary guidance scenario from the multiple space environment alarm events stored in the database in response to the temporary guidance operation, and use it as the temporary guidance space environment monitoring data for space environment training to replace the target space environment monitoring data of the unexecuted period; and based on the temporary guidance space environment monitoring data, update the space environment current report data and the space environment forecast data. For example, the temporary guidance space environment monitoring data can be input into the corresponding space environment model to obtain the updated space environment current report data. For example, based on the temporary guidance space environment monitoring data, the updated space environment current report data and the neural network model, the updated space environment forecast data for the future time period can be obtained, thereby realizing the update of the space environment current report data and the space environment forecast data.

[0057] Accordingly, the mission risk determination module 104 can also be used to respond to temporary guidance operations and calculate the space environment risk information of the training scenario after temporary guidance based on target equipment data, temporary guidance space environment monitoring data, updated space environment current report data and updated space environment forecast data.

[0058] Accordingly, the training scene presentation module 105 can also be used to respond to the temporary guidance operation and present the training data after temporary guidance through a three-dimensional dynamic scene and a data change chart; The report preparation module 106 can also be used to respond to temporary guidance operations, generate a preliminary risk assessment report for the temporary guidance scenario of the space environment based on the training data after temporary guidance and the space environment risk information, receive revision information entered by trainees during the training process, and revise the preliminary risk assessment report based on the revision information to obtain the final risk assessment report for the temporary guidance scenario of the space environment.

[0059] In this way, through temporary guidance, the system can simulate more realistic and complex space environment scenarios, especially sudden events (such as solar storms, communication interference, etc.). This practical training method can better help students master emergency response skills. On the other hand, through temporary guidance, training can be better adapted to the ability levels and learning progress of different students. On the other hand, the temporary guidance module allows instructors to set targeted training scenarios based on the students' weaknesses or specific needs. This personalized training can help students quickly improve specific abilities.

[0060] According to some embodiments of the present application, optionally, the data change chart may include at least one of a line chart, a bar chart, a carousel chart, and a color temperature chart, and the data change chart may present training data that changes over time to show changes in the space environment.

[0061] Data change charts are important tools for visualizing training data in space environment training systems. They can present space environment data that changes over time (such as X-ray flux, geomagnetic index, particle flux, etc.) in an intuitive way. For example, a line chart can display continuous data that changes over time (such as particle flux), helping students to observe trends intuitively. For example, a bar chart can compare data at different time points or with different parameters (such as the Kp index), making it easier for students to quickly identify key changes. For example, a carousel can dynamically display the changes in multiple parameters and enhance the visualization of data (such as a solar image). For example, a color temperature chart can reflect data intensity through color changes (such as a particle flux distribution chart), allowing students to quickly locate high-risk areas.

[0062] In this way, the data change chart presents complex space environment data in a graphical way, allowing students to quickly understand the changing trends and key information of the data. In addition, the data change chart can be updated in real time, and the changes in training data can be presented synchronously with the three-dimensional dynamic scene, helping students make quick decisions in a dynamic environment. The data change chart is not only helpful to students, but also provides instructors with intuitive teaching tools and evaluation basis.

[0063] According to some embodiments of the present application, optionally, the space environment training system supports a combination of automatic and manual methods to evaluate the students' performance. Among them, the content of the automatic grade determination is mainly clear and quantified information, and the manual grade determination content is mainly summary description information, which can be manually scored by the instructor. Specifically, the space environment training system 10 can also include a training performance evaluation module, which can be used to divide the multiple scoring items in the final risk assessment report into a first category and a second category based on preset scoring requirements. The first category can be clear and quantified scoring items, such as monitoring data values, forecast data values, space environment alarm events, space environment alarm events, etc. The second category can be non-quantitative scoring items, such as the causes of space environment alarm events and emergency response recommendations.

[0064] The training performance evaluation module can also be used to automatically score the scoring items of the first category, push the scoring items of the second category to the instructor for manual scoring, and after manual scoring, summarize the scoring results of the scoring items of the first category and the scoring items of the second category to obtain a total score.

[0065] According to some embodiments of the present application, optionally, the space environment training system 10 may also include a review and deduction module, which may be used to record training data, operation information of trainees and instructors during training, and a final risk assessment report, to facilitate subsequent review and deduction.

[0066] In this way, during the training process, the space environment training system supports the recording of training mission scenario information, space environment scenario information, trainee and instructor operation information, and the final risk assessment report, which can facilitate subsequent review and deduction, help trainees identify problems, and facilitate subsequent improvements.

[0067] Taking into account that in a few cases, the space environment alarm event database may not store historical space environment monitoring data of space environment alarm events that completely correspond to the space environment scenarios set by the instructor or the space environment temporary guidance scenarios, which may result in the data not being able to be queried or the queried data being inaccurate.

[0068] In view of this, according to some embodiments of the present application, optionally, the training data generation module 103 can be specifically used to query the historical space environment monitoring data of the target space environment alarm event that has the same type as the set space environment alarm event, and whose space environment event alarm level and space environment alarm event duration are closest to each other from the multiple space environment alarm events stored in the space environment alarm event database. That is, it is ensured that the event type of the queried target space environment alarm event is the same as the set space environment event type, and the space environment event alarm level and space environment alarm event duration are closest to each other. For example, if both are solar proton events, there may be certain differences in their space environment event alarm levels and / or their space environment alarm event durations.

[0069] If the target item data in the historical space environment monitoring data does not meet the data requirements of the set space environment event alarm level, the target item data is adjusted, and other data except the target item data in the historical space environment monitoring data is extracted, and the adjusted target item data is combined with the other extracted data to obtain the target space environment monitoring data.

[0070] Specifically, the target item data is an important factor in evaluating or distinguishing the event type and alarm level of the space environment alarm event. The target item data corresponding to the space environment alarm event of different event types may be different. For example, the target item data corresponding to the solar proton event is the GEO orbit proton data, which can be specifically the GEO orbit 10MeV proton integrated flux. For example, for the solar proton event, the GEO orbit 10MeV proton integrated flux is In between is the yellow alert level, In between is the orange alert level. The above is the red alert level.

[0071] Taking the solar proton event as an example, if the GEO orbit 10MeV proton integrated flux in the queried historical space environment monitoring data does not meet the data requirements of the set space environment event alarm level, such as the space environment event alarm level set by the instructor is the orange alarm level, the range corresponding to the orange alarm level is However, the 10MeV proton integrated flux in the GEO orbit in the historical space environment monitoring data was not in At this time, the GEO orbit 10MeV proton integrated flux in the historical space environment monitoring data can be adjusted to meet the data requirements of the set space environment event alarm level, and other data except the GEO orbit 10MeV proton integrated flux in the historical space environment monitoring data can be extracted, and the adjusted GEO orbit 10MeV proton integrated flux can be combined with the other extracted data to obtain the target space environment monitoring data.

[0072] In this way, in most or even all cases, it can be guaranteed that the target space environment monitoring data that is closest to the space environment scenario set by the instructor or the temporary guidance scenario of the space environment can be successfully acquired, thereby improving the success rate and accuracy of training data acquisition.

[0073] Based on the same technical concept as the space environment training system based on historical data provided by the above product embodiment, the present application also provides a training method based on the space environment training system.

[0077] S304: Calculate the space environment risk information of the current training scenario based on the target equipment data, target space environment monitoring data, space environment current report data and space environment forecast data used in the training.
