In addition, with the widespread application of payload digitalization technology on spacecraft and the introduction of spacecraft on-orbit service application technology, on-orbit empowerment of spacecraft software and hardware will become more and more common and frequent, and at the same time, it will bring about a faster update frequency of heterogeneous spacecraft information data.

[0003] The information data of spacecraft contains the important status of each subsystem of the spacecraft, reflects the performance characteristics or functional status of the spacecraft, and is an important basis for health diagnosis and fault prediction of the spacecraft. At present, the analysis and judgment of spacecraft information data depends on the data type, threshold range, and data processing method of telemetry parameters, and all of these contents come from the manual editing and updating of special format files by ground staff. When the number of telemetry parameters increases, the number of heterogeneous spacecraft is increasing, the functions of each spacecraft payload are different, and the functions of heterogeneous spacecraft are frequently updated, the re-editing of format files will bring huge manual load and potential reliability risks.

[0008] Among them, the parameter code is uniformly arranged in the form of sub-addresses and sequence numbers; the parameter type is used to distinguish state quantities and statistical quantities; the statistical method is used for the onboard computer to select basic mathematical processing methods, including upper and lower boundary judgments, mean statistics, standard deviation statistics, and rate of change calculations.

[0034] When the functions of heterogeneous spacecraft change or require on-orbit repair and assembly due to hardware failure, it is possible to quickly detect the new module, register the analog data collection of the new module, dynamically configure system-level functions, and use common data structures and processing methods to perform health assessments on the collected analog quantities; and

[0035] When the payload functions of heterogeneous spacecraft change, a unified data source operation mechanism is used to achieve the following effects:

[0036] It does not rely on human assistance and ground support, and uses a unified information flow format to achieve standardized health assessment of functional processes. It automatically identifies methods for determining the health of information data. The health determination methods include trend analysis, boundary detection, mean check, expected value check, and deviation check. It can rely on the adaptive standardized design of spacecraft software to achieve highly adaptable normal operation.

[0037] Optionally, in the adaptive management method for the health of heterogeneous spacecraft, the hardware interface of the payload of the heterogeneous spacecraft adopts a standardized design including:

[0038] The analog quantities of heterogeneous spacecraft are all collected through analog quantity acquisition terminals. The analog quantity acquisition terminals judge the hardware health status of heterogeneous spacecraft according to the standardized analog quantity threshold range, and the judgment results are sent to the onboard computer through the bus.

[0039] Optionally, in the adaptive management method for the health of heterogeneous spacecraft, the software functions of the payload are related to the missions of the heterogeneous spacecraft. When the heterogeneous spacecraft is enabled on orbit, information data related to its functions are used through standardized data interfaces to perform adaptive judgment on its health status.

[0040] The inventor of the present invention has found through research that the traditional spacecraft data management strategy mostly collects information data of each subsystem through the onboard computer, transmits it to the ground through the measurement and control channel, and performs fault diagnosis on the ground through a special rule format file. This spacecraft data management method has the following defects:

[0041] Waste of measurement and control channel resources. During the life cycle of a spacecraft in orbit, some telemetry parameters show normal status for a long time, and some telemetry parameters are used to assist fault diagnosis, which leads to the waste of spacecraft measurement and control channel resources under normal operation.

[0042] Waste of human resources in updating and maintaining telemetry data. With the advancement of spacecraft hardware interface standardization technology, a large number of spacecraft are very likely to experience on-orbit hardware replacement and software re-enabling during their long-life operation. Currently, the processing and maintenance of telemetry data are completed through software and configuration files. The telemetry processing software relies on the telemetry configuration file to judge the correctness of the data, and the file uses the traditional manual input and maintenance mode, which wastes human resources and also poses the risk of data editing errors.

[0043] The health management is not real-time enough. The current status of spacecraft health management is to transmit most of the information data to the ground for processing. When the visible arc of some spacecraft is short, the spacecraft health management is only carried out through real-time telemetry of the visible arc and a large amount of delayed telemetry, which will cause the spacecraft health management to be not real-time enough.

[0044] Based on the above insights, the inventors of the present invention found that in order to overcome the shortcomings of the prior art, the key problem that needs to be solved currently is to propose that heterogeneous spacecraft must have the ability to standardize the design of information data formats and autonomously interpret and manage them, thereby realizing integrated management of heterogeneous spacecraft information from system design to autonomous fault diagnosis, so as to achieve the purpose of improving the efficiency of autonomous health management of heterogeneous spacecraft.

[0045] In the adaptive management method of the health of heterogeneous spacecraft provided by the present invention, in view of the problems of complex structure of the source of telemetry data of heterogeneous spacecraft, complicated and redundant categories, and large differences in information standardization between similar design objects, the design scheme of the present invention intends to adopt a multi-task standard platform to standardize the mechanical, electronic and data interfaces of the payload. When the heterogeneous spacecraft has an on-orbit software function upgrade or the hardware has on-orbit assembly and service requirements, after different functional modules or the same functional modules are replaced, the newly replaced modules can be quickly detected. At the same time, the platform and payload information data format of the heterogeneous spacecraft adopts standardized and universal compatible technology, and the spacecraft onboard information transmission system adopts a universal model, thereby realizing the design standardization and management universalization of replaceable, multi-feature, and similar heterogeneous objects.

It should be noted that the accompanying drawings are in a very simplified form and are not in precise proportions, and are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present invention.

[0057] The purpose of the present invention is to provide an adaptive management method for the health of heterogeneous spacecraft to solve the problem that the existing spacecraft telemetry parameter processing brings huge manual load and potential reliability risks.

[0058] To achieve the above-mentioned objectives, the present invention provides an adaptive management method for the health of heterogeneous spacecraft, comprising: a multi-task standard platform is configured to perform standardized design on the mechanical interface, electronic interface and data interface of the payload, so as to achieve the following effects: when the heterogeneous spacecraft undergoes on-orbit software function upgrades or on-orbit hardware assembly and service requirements, after different functional modules or the same functional modules are replaced, the multi-task standard platform can quickly detect the newly replaced modules; the data format standard platform is configured to make the information data format of the satellite platform and payload of the heterogeneous spacecraft adopt a standardized and universal data format, and to make the onboard information transmission system of the heterogeneous spacecraft adopt a universal model, so as to realize the standardization of the design and universal management of heterogeneous objects.

[0059] In view of the problems of complex structure of telemetry data sources of heterogeneous spacecraft, complicated and redundant categories, and large differences in information standardization between similar design objects, the design scheme of the present invention intends to adopt a multi-task standard platform to standardize the mechanical, electronic and data interfaces of the payload. When the heterogeneous spacecraft has on-orbit software function upgrades or the hardware has on-orbit assembly and service requirements, after different functional modules or the same functional modules are replaced, the newly replaced modules can be quickly detected. At the same time, the platform and payload information data format of heterogeneous spacecraft adopts standardized and universal compatible technology, and the spacecraft onboard information transmission system adopts a universal model, so as to realize the design standardization and management generalization of replaceable, multi-feature, and similar heterogeneous objects.

[0060] The information data of spacecraft payloads can be divided into analog quantities that characterize the health status of hardware, digital quantities that reflect functional completeness, and application data for functional synthesis. A standardized design scheme is adopted for the hardware of heterogeneous spacecraft payloads. When the functions of heterogeneous spacecraft change or in-orbit maintenance and assembly is required due to hardware failure, the analog data collection of the new module can be registered after the new module is quickly detected, the system-level functions can be dynamically configured, and the collected analog quantities can be evaluated for health using a common data structure and processing method. In addition, when the functions of heterogeneous spacecraft payloads change, the design scheme of this technology adopts a unified data source operation mechanism, which can achieve standardized health assessment of functional processes in a unified information flow format without relying on manual assistance and ground support, and automatically identify methods for judging the health of information data, including trend analysis, boundary detection, mean check, expected value check, deviation check and other health assessment methods, that is, it can rely on the adaptive standardized design of spacecraft software to achieve highly adaptable normal operation.

[0061] Heterogeneous spacecraft payload hardware interfaces adopt standardized designs, such as Figure 1As shown, the analog quantities of heterogeneous spacecraft are collected through analog quantity acquisition terminals. The analog quantity acquisition terminals judge the hardware health status of heterogeneous spacecraft according to the standardized analog quantity threshold range, and the judgment results are sent to the onboard computer through the bus. The software functions of the payload are related to the missions of the heterogeneous spacecraft. When the heterogeneous spacecraft is enabled on orbit, the information data related to its functions can be adaptively judged for its health status through standardized data interfaces. The adaptive management methods for the health of heterogeneous spacecraft using information data standardization design schemes are as follows:

[0062] First, it includes information data structure standardization design technology: such as Figure 2 As shown in Table 1, the payload with a standardized interface adopts a universally designed information data interface. Each standardized designed payload sends an information data parameter table representing the health status of a single machine to the onboard computer through the bus. The parameter table includes the number of parameters, parameter length, parameter code, parameter value, parameter type, statistical method, and judgment threshold. Among them, the parameter code is uniformly arranged in a sub-address and sequence number; the parameter type is used to distinguish between state quantities and statistical quantities; the statistical method is used for the onboard computer to select basic mathematical processing methods, including upper and lower boundary judgments, mean statistics, standard deviation statistics, and change rate calculations.

[0063] Table 1 Information data interface of universal design

[0064]

[0065] The onboard computer has a large storage capacity. For information data that needs to be judged based on long-term data, it is stored in the memory using the parameter code as the retrieval mark and the rate of change is calculated regularly.

[0066] Secondly, it includes the standardized design technology of fault event packages: such as Figure 2 As shown in Table 2, the onboard computer receives the telemetry parameters sent by the payload, makes a health judgment based on the parameter type, and then writes the judgment result into a generalized fault event package, as shown in Table 2:

[0067] Table 2 Fault event package of universal design

[0068]

[0069]

[0070] like Figure 2 As shown in the figure, the methods for writing fault event packages to the onboard computer are:

[0071] For state quantity parameters: In order to save telemetry resources, the onboard computer only writes the parameter code and abnormal time code of the abnormal state in the fault event package. The fault type in this type of fault package is set to 1.

[0072] Regarding statistical parameters: for telemetry that calculates the mean, when the amplitude of the mean jump exceeds the threshold value, this phenomenon is added to the fault event package, and the fault type is located as 2; for telemetry that calculates the rate of change, when the rate of change for a certain period of time exceeds the threshold value, this phenomenon is added to the fault event package, and the fault type is determined as 3; other types of statistics can be deduced accordingly based on the actual telemetry statistical method of the standardized load.

[0073] The present invention proposes a heterogeneous spacecraft adaptive management technology based on information data standardization design, and its innovations and advantages are:

[0074] The information data of heterogeneous spacecraft are standardized and classified, namely, analog quantities used to characterize the basic health status of hardware, statistical quantities used to predict the aging trend of hardware, state quantities used for rapid diagnosis, and massive data used for application function generation. When heterogeneous spacecraft are enabled in orbit, they can complete the adaptive management of their health status through standardized information data formats and processing methods without ground intervention.

[0075] Heterogeneous spacecraft payloads are plug-and-play on-orbit based on hardware standardization design, automatically collect analog quantities and perform adaptive health status judgment through standard threshold ranges;

[0076] Heterogeneous spacecraft payloads realize on-orbit adaptive operation of onboard autonomous health management software based on standardized design of data interfaces;

[0077] Among the telemetry parameters, only fault event packages and massive application data generated for payload applications are transmitted in real time, which greatly reduces the waste of measurement and control resources.
