Description

Technical Field

[0001] This application relates to the field of aerospace measurement and control, and specifically to a method and device for real-time monitoring of the status of an aerospace measurement and control application software system. Background Art

[0002] With the development of the aerospace industry, the complexity of aerospace missions has been increasing. As a result, the scale of aerospace measurement and control application software systems has become larger, the complexity has become higher, and the correlation between subsystems has also become higher. A large number of statuses of aerospace measurement and control application software systems need to be monitored in real time, and problems and abnormal warnings can be processed in a timely manner. Traditional operation and maintenance monitoring management tools cannot meet the requirements for monitoring and predicting the health status and operation trends of large software systems. Therefore, it is of great practical significance to study a method for real-time monitoring and display of the status of aerospace measurement and control application software systems.

[0003] Currently, aerospace measurement and control tasks are becoming increasingly heavy, and there are more and more software that needs operation and maintenance monitoring. The main problems faced by aerospace measurement and control software operation and maintenance technology include:

[0004] First, large-scale software of different types cannot be uniformly monitored. The scale of aerospace measurement and control application software systems is huge, the division of labor of software is becoming more and more detailed, involving hundreds of servers and thousands of software processes. The existing technology cannot uniformly monitor the entire application software system, cannot quickly locate faults, the fault handling efficiency is low, and the discovery of faults is limited to the warning state, and it is impossible to discover other potential or related warning states by analogy, and it is impossible to associate software status with reasons such as hardware and network.

[0005] Second, it is impossible to evaluate the system operation trend and give risk warnings. Currently, the aerospace measurement and control software operation and maintenance system cannot display and predict the health status and operation trends of each application software process, cannot give early warnings of potential risks that may occur, and at the same time cannot judge whether the system needs to be optimized and expanded.

[0006] Third, it is impossible to dynamically monitor multi-target aerospace measurement and control application software. With the frequent increase of aerospace missions, the task targets that need to be monitored will also change frequently, and the application software that needs to run will be continuously launched and taken offline, that is, the content of aerospace measurement and control software operation and maintenance management needs to change dynamically with the changes of on-orbit target spacecraft, so as to avoid unnecessary missed detections and false detections in operation monitoring. The existing technology fails to achieve the above goals.

[0060] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer and more understandable, the following further elaborates on the embodiments of this application with reference to the accompanying drawings. Here, the illustrative embodiments and descriptions of the embodiments of this application are used to explain the embodiments of this application, but do not limit the embodiments of this application.

[0061] In the technical solutions of this application, the information collected is information and data authorized by the user or fully authorized by all parties. Moreover, for the processing of relevant data such as collection, storage, use, processing, transmission, provision, disclosure, and application, all comply with the relevant laws, regulations, and standards of the relevant countries and regions, necessary confidentiality measures are taken, it does not violate public order and good customs, and a corresponding operation entry is provided for the user to choose to authorize or reject.

[0062] Provide a corresponding operation entry for the user to choose to agree or reject the automated decision-making result; if the user chooses to reject, then enter the expert decision-making process.

[0063] In one embodiment, in order to be able to perform real-time monitoring and display of the status of the space TT&C application software system, this application provides a method for real-time monitoring of the status of the space TT&C application software system. Refer to Figure 5 , including:

[0064] S101: Use a pre-constructed orchestration algorithm to perform parallel command orchestration on each subsystem in the space TT&C application software system to obtain the operating parameters of each subsystem;

[0065] S102: Perform trend analysis and real-time dynamic monitoring on the operating parameters to obtain the operating status of each subsystem;

[0066] S103: Perform hierarchical display of the operating status of each subsystem according to the server cluster corresponding to each subsystem and the space TT&C target.

[0067] It can be understood that the embodiments of this application provide a method for real-time monitoring and display of the status of the space TT&C application software system for the requirements such as rapid fault location of the space TT&C application software, display and prediction of system status change trends, and dynamic monitoring of multi-target space TT&C application software. In the embodiments of this application, the method for real-time monitoring and display of the status of the space TT&C application software system is divided into three levels: data acquisition layer, data processing layer, and data display layer. Refer to Figure 1 as shown. It solves key problems such as rapid fault location, fault correlation, operation trend judgment, and dynamic expansion through a decoupled and modular approach.

[0068] In the embodiments of this application:

[0069] 1. Unified monitoring of large-scale software of different types. In the embodiments of the present application, for the complex scenarios of large-scale space TT&C application software systems, there are problems such as inconsistent monitoring content for different types of software, multiple processes with the same name may be started on the same server, and the process ID changes due to process restart, making it impossible to conduct unified analysis. A unique application software (which can be called a subsystem) is determined by the program name + key parameters + host name + environment variables. According to the configured items to be monitored, the startup situation, resource usage situation, and process running status are respectively obtained and compared with their corresponding threshold parameters, and finally the comprehensive software running status is obtained.

[0070] 2. Hierarchical display of the status of the space TT&C application software system. In the embodiments of the present application, for the problem of unified display of the status of large-scale space TT&C application software systems, rapid information collection is achieved by using parallel collection and reduction parsing methods in the data collection layer, and rapid fault discovery is achieved by using hierarchical structure display and health status priority sorting reduction methods. For example, first, the normal and abnormal status information is displayed in the outermost software configuration item area. By using the method of status drilling down, it can be drilled down to the second layer to display the normal and abnormal status of the spacecraft target corresponding to this software configuration item. Through the spacecraft target, it can be drilled down to the third layer to display the normal and abnormal status of the server host and all processes under the configuration item corresponding to the spacecraft target corresponding to this software configuration item. The rapid collection in the data collection layer and the hierarchical integration in the data display layer achieve the real-time hierarchical display of the status of the space TT&C application software system.

[0071] 3. Dynamic monitoring of multi-target space TT&C application software. Dynamic monitoring of the status of space TT&C application software is achieved through the dynamic expansion of the monitored objects in the data processing layer, avoiding strong dependence on operation and maintenance personnel. It is possible to only monitor the status of the on-orbit target spacecraft that needs to be concerned currently, and the status of the spacecraft that has already left the orbit or known abnormal status can be ignored. At the same time, the rule library can be dynamically maintained, that is, the information such as the content to be monitored for each type of software, the rules and thresholds of the monitored content, to achieve dynamic monitoring of the status of multi-target space TT&C application software.

[0072] 4. Display and prediction of the trend of system status changes. Through the trend analysis of the resource usage and resource health status of space TT&C application software, pre-judgments are made on abnormal resource usage such as memory overflow and abnormal CPU occupancy, effectively warning the operation and maintenance personnel so that they can take measures such as early capacity expansion or restart.

[0073] As can be seen from the above description, the real-time monitoring method for the state of the space TT&C application software system provided by this application can achieve unified monitoring of the states of large-scale space TT&C application software systems through hierarchical display of the states of the space TT&C application software system; the system states are clear and intuitive, and the system fault points can be quickly discovered and located, laying a foundation for realizing the automated operation and maintenance of the space TT&C application software system, conforming to the development trend of large-scale space missions; the display and prediction of the system state change trend can facilitate the discovery of potential hidden dangers and problems in the space TT&C application software system; through the mechanism of dynamic monitoring and abnormal warning of multi-target space TT&C application software, the operation and maintenance monitoring efficiency is greatly improved.

[0074] In one embodiment, referring to Figure 6 , the parallel command orchestration of each subsystem in the space TT&C application software system is performed by using a pre-constructed orchestration algorithm to obtain the operation parameters of each subsystem, including:

[0075] S201: Construct an orchestration algorithm according to the operation parameters to be collected for each subsystem; wherein, the operation parameters include resource information, log information, and resource status information; the orchestration algorithm includes a parameter acquisition command, a parameter traversal order, a parameter storage format, and a parameter sampling window;

[0076] S202: Issue the parameter acquisition command to each subsystem according to the parameter traversal order to perform parallel parameter acquisition;

[0077] S203: Standardize and store the collected operation parameters according to the parameter storage format.

[0078] It can be understood that steps S201 to S203 correspond to the data acquisition layer. The data acquisition layer is mainly responsible for collecting different software states from the server sides of the space TT&C application software system (including various space TT&C application software) and sending them to the data processing layer for data analysis. Here, the data acquisition layer can adopt a parallelized method to request the application software states of the server sides of the space TT&C application software (also called subsystems), and reduce the request results to a unified text for unified processing. The acquisition content of the data acquisition layer includes: resource information, log information, status information, etc. of each application software (system software can also be included), and also includes the resource status information of each server, etc. There are many design subsystems in the space TT&C application software, involving various application modes, including load balancing clusters, primary and standby servers, master and slave servers, etc., and the deployment modes of different application software on the same server are also different. Therefore, when collecting operation parameters, it is necessary to comprehensively consider the application modes of each software, be compatible with the collection methods of all application modes, and dynamically collect different status contents according to different application modes. Moreover, for the convenience of deployment, it is not possible to install probe software on each server, and dynamic collection needs to be carried out without installing collection software on the collection end. Therefore, it cannot directly apply existing data collection tools, but needs to construct an orchestration algorithm according to the status to be collected on all servers, and in the form of command orchestration, send commands to each server to complete parallel status collection. For example, some software is deployed in cluster A and the process CPU status needs to be collected with a collection period of T1; some software is deployed in cluster B and the handle count needs to be collected with a collection period of T2; some software is deployed in cluster C and the process memory status needs to be collected with a collection period of T3. Here, the collection commands with different periods distributed to specific hosts will be orchestrated and processed, and multiple collection commands that can be merged will be merged to reduce the execution pressure of the collection commands on the server.

[0079] As can be seen from the above description, the method for real-time monitoring of the status of the space TT&C application software system provided by this application can perform parallel command orchestration on each subsystem in the space TT&C application software system by using the pre-constructed orchestration algorithm to obtain the operation parameters of each subsystem.

[0080] In one embodiment, referring to Figure 7 , performing trend analysis and real-time dynamic monitoring on the operation parameters to obtain the operation status of each subsystem includes:

[0081] S301: Perform aggregation analysis on each subsystem to obtain a subsystem set; where each subsystem in the subsystem set corresponds to the same space TT&C target and the same server cluster;

[0082] S302: For each subsystem set, perform dynamic fitting on the operating parameters under each parameter sampling window, and determine whether there are overlimit conditions in controller occupancy, database connection count, and memory overflow according to the fitting results, so as to obtain the trend analysis result;

[0083] S303: Conduct comprehensive comparison and judgment on the trend analysis result to determine the on-orbit and off-orbit status of the space TT&C target;

[0084] S304: Perform real-time dynamic monitoring on the space TT&C target according to the on-orbit and off-orbit status.

[0085] It can be understood that steps S301 to S304 correspond to the data processing layer. The data processing layer mainly processes the results collected by the data acquisition layer, mainly integrating different information belonging to the same application software. See Figure 2 . And expand the application software status in a tree structure, and perform aggregation analysis on the software status belonging to the same target and the same cluster through an aggregation algorithm. Here, the target refers to a specific model spacecraft, such as the TT&C software status of a certain spacecraft; and the aggregation of the status of the same cluster can, for example, refer to the aggregation analysis of the data processing software status deployed by the spacecraft on the data processing cluster.

[0086] The data processing layer also includes two functions: trend analysis and dynamic expansion function.

[0087] Trend analysis: mainly perform trend analysis on the application software index data of different sampling windows, obtain fault information such as overlimit CPU occupancy, overlimit database connection count, and memory overflow information, and give early warnings of possible risks such as insufficient resources in advance. The specific steps are to perform dynamic fitting on the index data of each program obtained, and at the same time compare with the upper limit of the threshold of each program configured, and perform trend analysis according to the eigenvalue of the fitting algorithm and the configured threshold to achieve trend warning. For example, according to the collected memory data, an autoregressive integrated moving average model can be used to judge memory leakage; according to the model fitting result, if there is no significant autocorrelation in the model residuals and the predicted value shows an upward trend, it indicates that the data has a monotonically increasing trend and there is a risk of memory leakage.

[0088] Dynamic expansion function: Automatically update the application software that needs to be monitored and displayed according to the changes of on-orbit targets in space missions, and dynamically update the content that needs to be collected and analyzed. For example, when a new target is launched, each application software under the new target needs to be included in the monitoring. When a target is deorbited, the application software of the deorbited target is no longer monitored. The dynamic expansion module will comprehensively and dynamically analyze the resource occupancy of each application software under the target, and automatically analyze the on-orbit and deorbited states of the target through a comprehensive comparison algorithm, so as to realize the dynamic update of the content that needs to be collected and analyzed. For example, when the spacecraft downlink data processing software is in the on-orbit state of the spacecraft, the collected CPU and memory states will show a periodic trend (more CPU and memory will be occupied when processing data within the tracking and control arc segment, and less CPU and memory will be occupied outside the arc segment). When the spacecraft is deorbited, there will be no more downlink data, and the CPU and memory occupied by the downlink data processing software inside and outside the tracking and control arc segment are relatively stable. Therefore, by collecting the software state and combining it with the tracking and control network plan for comparison, the on-orbit and deorbited states of the target can be automatically analyzed, so as to realize the dynamic update of the content that needs to be collected and analyzed.

[0089] As can be seen from the above description, the method for real-time monitoring of the state of the space TT&C application software system provided by this application can perform trend analysis and real-time dynamic monitoring on the operating parameters, and obtain the operating states of each subsystem.

[0090] In one embodiment, refer to Figure 8 , the hierarchical display of the operating states of each subsystem according to the server cluster corresponding to each subsystem and the space TT&C target includes:

[0091] S401: Construct the hierarchical display relationship of each subsystem according to the server cluster corresponding to each subsystem and the space TT&C target;

[0092] S402: Display the operating states of each subsystem according to the hierarchical display relationship.

[0093] It can be understood that steps S401 to S402 correspond to the data display layer. The data display layer mainly displays the operating states of tens of thousands of space TT&C applications on the same page, and regards each space TT&C application software as a node of a tree structure. The data display layer hierarchically displays the health states of each space TT&C application software, and can perform tree-priority reduction display on the health states of each space TT&C application software according to the priority. For example, Figure 3 displays the health states of each space TT&C application software from the software perspective, Figure 4 and displays the health states of each space TT&C application software from the hardware perspective.

[0094] As can be seen from the above description, the real-time monitoring method for the state of the aerospace TT&C application software system provided by this application can hierarchically display the operating states of each subsystem according to the server cluster corresponding to each subsystem and the aerospace TT&C target.

[0095] In summary, the method provided by this application has at least the following advantages:

[0096] 1. Realize unified monitoring of large-scale software of different types. Determine a unique application software through the program name + key parameters + host name + environment variables, and respectively obtain the process startup situation, resource usage situation, process running state, host state, etc. according to the configured rules and thresholds of the content to be monitored, and compare them with the corresponding rule and threshold parameters, and finally obtain the comprehensive software running state.

[0097] 2. Realize hierarchical display of the state of the aerospace TT&C application software system. Display the normal and abnormal state information in the outermost software configuration item area. By using the method of state drilling down, it can be drilled down to the second layer to display the normal and abnormal states of the spacecraft target corresponding to this software configuration item. Through the spacecraft target, it can be drilled down to the third layer to display the normal and abnormal states of the server host corresponding to the spacecraft target corresponding to this software configuration item and all processes under the configuration item. Through the state hierarchical display and the health state priority sorting and reduction method of the embodiments of this application, rapid discovery of faults can be realized.

[0098] 3. Realize dynamic monitoring of multi-target aerospace TT&C application software. Through methods such as dynamic expansion of the monitored object, ignoring the monitoring of the off-orbit spacecraft target, ignoring the monitoring of known abnormal states, and dynamic maintenance of the monitoring rule library and thresholds, realize dynamic monitoring of the state of the aerospace TT&C application software, that is, only monitor the state of the on-orbit target spacecraft that needs to be concerned currently, and ignore the state of the spacecraft that has already been off-orbit or ignore the known abnormal states.

[0099] 4. Realize the display and prediction of the system state change trend. Through trend analysis of the resource usage and resource health state of the aerospace TT&C application software, predict abnormal resource usage such as memory overflow and abnormal CPU occupancy, and realize early warning of the abnormal change trend of the system.

[0100] Based on the same inventive concept, an embodiment of the present application further provides a real-time monitoring device for the state of an aerospace TT&C application software system, which can be used to implement the method described in the above embodiments, as described in the following embodiments.
