Electromagnetic Compatibility Fault Analysis of Temperature and

Pressure Composite Sensor Based on Dynamic Fault Tree

Qin Qi-sen

[Abstract]The analysis method of fault tree is an effective method for fault diagnosis and search. In this paper， a fault tree is established for the electromagnetic compatibility fault of a certain type of temperature and pressure composite sensor， and a dynamic fault tree is introduced. The possible fault modes are listed and simulated The feasibility and accuracy of the theoretical analysis are verified by the method of experiment. The theoretical analysis of the fault tree is well verified.
