Health state assessment method for the spaceflight measurement and control data transmission integrated equipment

Abstract

The health state assessment method for the spaceflight measurement and control data transmission integrated equipment is high in feasibility and high in assessment conclusion credibility. According to the technical scheme, in AHP software, an equipment-level and component-level health management module, a parameter-level health management module, a subsystem-level health management module and a system-level health management grading module are adopted to form a layered health management evaluation system architecture; the equipment-level and component-level health management module collects electric signals and characterization parameters of equipment circuit modules or components and devices; various parameter signals are fused to jointly predict health states of components and equipment, and the parameter-level health management module carries out state prediction and management on parameter changes; the subsystem-level health management module performs health assessment and prediction; and the system-level health management grading module analyzes and predicts a task execution form, constructs and forms a multi-level analysis evaluation model, calculates a weight coefficient, performs layer-by-layer weight fusion and performs evidence synthesis to obtain an evaluation result of a system comprehensive state.

Description

technical field [0001] The invention relates to a health state evaluation technology mainly applied to comprehensive equipment of aerospace measurement, control and digital transmission. To solve the problem that traditional fault diagnosis and periodic maintenance can no longer meet the requirements of equipment use, a layered evaluation architecture, a system health evaluation method based on AHP, and equipment task performance evaluation are used to achieve reliable and efficient use of equipment. Background technique [0002] Equipment health management is developed with the progress of fault diagnosis technology. Its connotation is to evaluate and predict the health status of equipment by analyzing the influencing factors of equipment health status and closely combining information such as status monitoring, maintenance, use, and environment. And based on the health status of the equipment, the maintenance strategy is reasonably selected, and the maintenance activities ...
