Because of DEDS characteristics when GBM system is working

it is very suitable to handle fault diagnosis using DEDS fault diagnosis theory.Basic theory of DEDS fault diagnosis and GBM fault diagnosis process are briefly reviewed.Take the fault diagnosis of GBM perfusion system as an example

based on DEDS fault diagnosis theory fault diagnosis process of GBM is detailed analyzed.Experimental results show that diagnosis effect of DEDS-based theory of fault diagnosis is obvious that proves the effectiveness of DEDS fault diagnosis theory in GBM fault diagnosis.
