Problems solved by technology

However, because the fault detection model of the autonomous health management mentioned above is designed for the fixed satellite mode, the fault detection threshold is relatively extensive, and it is impossible to detect the deterioration trend of the satellite in time, especially unable to adapt to the health management requirements of remote sensing satellites with changing working modes and complex satellite states.

Abstract

The invention discloses a remote sensing satellite autonomous health management system. The system comprises a basic data management module, an operation state management module, a mode conversion management module, a health state detection module and a system health management module. According to the invention, the working mode of the remote sensing satellite is continuously changed; according to the remote sensing satellite fault isolation reconstruction method, the targeted autonomous health management function is still realized, the influence of different working modes on the refinement degree of the health management criterion is avoided, the accuracy degree of the fault isolation reconstruction operation is improved, and the continuous and stable operation capability of the remote sensing satellite is further improved.

Description

technical field [0001] The invention belongs to the technical field of overall satellite design, and in particular relates to an autonomous health management system for remote sensing satellites. Background technique [0002] Autonomous health management of spacecraft refers to the ability to operate independently, safely and reliably without relying on ground support. The degree of autonomy reflects the degree of dependence of spacecraft health management on the ground and operators. Autonomous health management technology can provide three capabilities of the spacecraft: first, real-time processing of satellite raw health telemetry data, extracting and downloading effective information, reducing the workload of ground system monitoring and interpretation one by one, and avoiding missed and wrong judgments; Predict the working status and development trend of system components according to the spacecraft failure prediction model or reliability model to avoid failures; the t...
