Study on Information Fusion Sensors Multiple for Drilling Fault Diagnosis
Zefu Bao · New Technology & New Process · 2009
This text describes the characters,form structure and concrete processing method of information fusion technology.And the application of information fusion in fault diagnosis proves the feasibility and validity from the angle of information theory.Based on this,it is combined the fault diagnosis of drilling fault diagnosis with information fusion,a method and model which the fau1t diagnosis of Drilling Fault Diagnosis information fusion is brought out.The evidential combination rule under different frame of discernment is presented,The method test model with the data from the locale in order to find the abnormity data and diagnose fault in time.so the maximum of available information is exploited and the uncertainty of the effective state between the potential states of a sensor is decreased,it is put on the fault diagnosis of procession and accuracy.
