Technical Field

The application relates to the technical field of system fault troubleshooting, in particular to a method and a device for quickly troubleshooting a guided system fault.

Background

At present, the troubleshooting of the system is mainly based on a Fault Tree Analysis (FTA), which describes the causal relationship among various events in the system by an event symbol, a logic gate symbol and a transition symbol through a special inverted Tree-shaped logical causal relationship diagram to perform top-down deductive failure Analysis on some major faults, so as to understand the cause of the system failure, find the best way to reduce the risk, or confirm a certain safety accident or the occurrence rate of a specific system failure. However, the fault tree analysis method has three limiting factors, namely, the fault tree analysis scheme is essentially fault deduction analysis performed from a failure scene, and cannot provide a judgment means to judge whether system faults are covered comprehensively, the fault tree analysis method can only analyze fault sets causing system failures, a stylized operation description for performing detailed troubleshooting on the fault sets to determine fault points is lacked, and the fault tree analysis method needs to design the failure scene and possible faults in advance by relying on existing knowledge and experience, and cannot provide effective fault troubleshooting support for unpredictable faults.

Technical personnel who can not meet the actual troubleshooting requirements for a special inverted tree-shaped logical causal relationship diagram in a fault tree analysis method propose a troubleshooting model constructed based on a system body, but at present, no troubleshooting scheme for the troubleshooting model constructed based on the system body exists, namely, troubleshooting of the troubleshooting model constructed based on the system body is blank at present.
