Environment Control System Fault Diagnosis Expert System
The Environment Control System (ECS) of transport category airplanes is inclined to breakdown due to many accessories.Once the system does not work well,it is difficult to locate the cause of the fault.The nets model and fault diagnosis way of Weighted Fuzzy Petri Net (WFPN) are explained,associating with the describable ability and fuzzy inferential ability of fuzzy Petri net graphics.Also,the structure and the working principle of the ECS fault diagnosis expert system are introduced.Furthermore,an example of pneumatic system (PNU)’s failure is used to verify the algorithm,and the result has shown that this method of the failure diagnosis is effective and feasible.
