Problems solved by technology

However, with the development trend of software-intensive micro-satellites, there are more and more software failures caused by the increasing software complexity. Therefore, it may be difficult to expose software abnormalities in a timely manner by relying solely on the status monitoring of on-board hardware.
In addition, although there are literatures mentioning some studies on on-board autonomous health management systems, these systems are not well classified and processed according to signal characteristics from the perspective of engineering implementation.
Due to the large amount of satellite sampling signals and the complex algorithms required for system analysis and processing, these systems are difficult to implement in the effective resource environment on the satellite

Abstract

The invention provides a hierarchical software health management method and system for microsatellites. The hierarchical software health management system performs hierarchical health management on satellites according to different subsystems, and comprises a sensor layer, a state monitoring layer, a health evaluation layer, a prediction layer, a decision processing layer and the like. Through software sensors deployed at operation key nodes of all sub-components of satellite housekeeping, the hierarchical software health management method collects running state data of each sub-component andanalyzes the running state data to obtain fault information, hierarchically evaluates the health condition of the current satellite system in combination with satellite historical telemetry data, software system knowledge and the fault information, pre-judges the health condition of the system at the future moment, and finally makes a health hazard strategy.

Description

technical field [0001] The invention relates to the field of fault diagnosis of satellite software, in particular to a micro-satellite-oriented software health management system. Background technique [0002] Although microsatellites are small in size and light in weight, compared with large satellites, their basic components have not been greatly reduced, but still include various sensors, actuators, and integrated management systems. At the same time, due to cost constraints, microsatellites usually use software redundancy to improve the reliability of the entire star. However, most of the satellite in-orbit failures involve software errors or abnormal software-hardware interaction scenarios. Therefore, this software redundancy design leads to software-intensive design, which greatly increases the probability of satellite in-orbit failures. In order to minimize fault propagation and its impact, once a fault occurs, it must be detected as soon as possible and its slow-chan...
