摘要
Abstract
During the launch process of a launch vehicle,abnormal telemetry parameters indicate the faulty state of rocket equipment.The traditional approach to fault localization,which relies on manual troubleshooting,is inefficient.This may lead to excessively prolonged fault resolution time,even delay the launch windows and cause serious consequences.To address this issue,this paper proposes a fault localization method for measurement systems based on Data Transmission Directed Graph(DTDG).The method defines fault localization rules based on the relationship between telemetry parameters and equipment nodes,and designs a corresponding fault localization algorithm.This enables rapid preliminary fault identification in single fault and multiple faults scenario.A case study in a simplified rocket measurement system model demonstrates that the method significantly improves the efficiency of fault localization.关键词
