Based on the correlation theory, the fault diagnosis reasoning method, which is established upon the assumption that system has two states: health and fault, can obtain diagnostic reasoning model and realize fault diagnosis.is, In addition to health or fault state, there is a clear intermediate state in many electronic products, namely sub-health state. This state is neither a health state nor a fault...
PHM (Prognostic and Health Management) is a new concept, which is to ensure the normal operation of the complicated system, to achieve its functionality and reliability better. In this situation, the remaining useful life (RUL) prediction has aroused more and more concerns. Although the life prediction methods are many, there are not a set of systemic of evaluation parameters to evaluate the accuracy...
Base on a comprehensive analysis of causes and classification of BIT false alarm, the stochastic characteristics mechanism of BIT false alarm is summarized, the parameters for BIT false alarm assessment is proposed, and the breakthrough of the method of BIT false alarm caused by which the noise analog and the research of BIT modeling and simulation methods considering stochastic characteristics. Therefore,...
Fault dictionary diagnosis methods is widely used in Testability field. Through looking up the fault table, fault dictionary can detect and isolate the fault of UUT. The principle of fault dictionary is: First of all, perform all the tests to get the test results for each test logic point (usually expressed as 0/1) and form state characteristics, Then one by one query fault dictionary to determine...
