Problems solved by technology

With the increase in the complexity of spacecraft missions, the design coupling between components and spacecraft increases, relying on manual traditional design of failure modes is prone to failure mode omissions, and it takes a lot of time to locate faults when omissions occur. And carry out the formulation of countermeasures, which delays the time to deal with the fault and makes the stable operation of the spacecraft hidden dangers.

Abstract

The invention relates to a logic model-based spacecraft system fault locating method. The method comprises the following steps of S1, building a spacecraft system logic model; and S2, receiving spacecraft telemetry information in real time, and comparing the spacecraft telemetry information with a state value set in the system logic model, thereby realizing fault locating. According to the method,the hidden danger of item omission of a fault mode in a conventional manual fault locating method is eliminated; the spacecraft system fault locating time is shortened; and the fault locating accuracy is improved.

Description

technical field [0001] The invention relates to the field of spacecraft system design, in particular to a logic model-based spacecraft fault location method. Background technique [0002] For a long time, the failure mode design of my country's spacecraft has mainly relied on the subjective cognition and experience of designers. The on-orbit operation and failure response of spacecraft are mainly completed by ground staff in real-time observation and by uploading control commands. With the increase in the complexity of spacecraft missions, the design coupling between components and spacecraft increases, relying on manual traditional design of failure modes is prone to failure mode omissions, and it takes a lot of time to locate faults when omissions occur. And to carry out the formulation of countermeasures, delaying the time to deal with the fault, so that there are hidden dangers in the stable operation of the spacecraft. Contents of the invention [0003] The purpose o...
