Abstract: The stable operation of the ground equipments in launch site is the premise to ensure the successful implementation of launch task. It is necessary to deeply analyze and quickly and accurately judge the operation state of the equipment. This paper studies the fault diagnosis method of ground equipments in launch site based on fault tree model, analyzes the fault types and fault analysis methods of ground equipments, and puts forward the description the relationship between system equipment and fault state based on T-S fuzzy model. The study results show that this method can quickly and accurately locate equipment faults and improve the efficiency of fault analysis. The research content of this paper can provide basis and reference for fault diagnosis of ground equipments in launch site.
Keywords: ground equipments in launch site; fault diagnosis; fault tree; T-S fuzzy
