Abstract

The invention discloses a method and a device for analyzing an abnormal state of a spacecraft in the operating process. The method comprises the following steps of: comparing telemeasuring data in a time period to be detected with historical data in a normal state so as to determine an abnormal condition of the telemeasuring data; under the condition that the telemeasuring data is abnormal, according to a correlation coefficient of sequences corresponding to the two groups of data, determining abnormality degree information of corresponding parameters of the telemeasuring data; according to spacecraft design data, establishing an incidence matrix of the corresponding parameters of the telemeasuring data and stand-alone equipment; according to associated data corresponding to the incidence matrix and the abnormality degree information, determining a fault probability of each piece of stand-alone equipment so as to analyze the possibility that the abnormal condition occurs to each piece of stand-alone equipment. The method and the device utilize the telemeasuring data so as to analyze the abnormal condition of the telemeasuring data, and solve the problem that due to shortage of a method for analyzing the abnormal state of the spacecraft in the operating process, a fault part cannot be determined when the spacecraft is abnormal in the operating process.

Description

technical field [0001] The invention relates to the field of fault prediction and detection, in particular to an analysis method and device for abnormal state of spacecraft operation. Background technique [0002] On-orbit spacecraft operate in the space environment for a long time, affected by multiple factors such as complex environment, working conditions and loads, their functions and performance may undergo abnormal changes, and these abnormal changes can usually be reflected by telemetry parameters, but they do not affect Make full use of the above information. [0003] In the prior art, there is a lack of a method for analyzing the abnormal state of the spacecraft during operation, resulting in the inability to determine the problematic parts when the spacecraft is abnormal in operation. Contents of the invention [0004] The present invention provides a method and device for analyzing the abnormal state of the spacecraft, which is used to solve the lack of a metho...
