 Abstract—According to the design procedure of fault selfdiagnosis system and features of automatic transmission system, the list of relation and mapping between fault symptoms and fault causes are made in this paper. Applying the approach of fault self-diagnosis based on fuzzy neural network, fault diagnosis of the automatic transmission electronic control system is realized. The structure of...

This paper develops the intelligent fault diagnosis system of reciprocating pump. The system takes fault diagnosis system as the core, using the Visual c++ as the software language. The software controls the data acquisition of pressure, position and flow signal synchronously. The different fault types corresponding signal curve is also different, so the main fault signal is pressure signal, fl...

Abstract: In this chapter, we introduce fault tolerance in Wireless Sensor Networks. Firstly, we start with a short description of sensor networks, fault tolerance and its different techniques. Then we discuss the different phases of fault tolerance (fault models, fault detection and identification at five levels of abstractions (physical, hardware, middleware, system software and applications)...

In this work an automatic fault classification system is developed for bearing fault classification of three phase induction motor. The system uses the wavelet packet decomposition using ‘db8’ mother wavelet function for feature extraction from the vibration signal, recorded for various bearing fault conditions. The selection of best node of wavelet packet tree is performed by using best tree a...

Active fault isolation of parametric faults in closed-loop MIMO systems are considered in this paper. The fault isolation consists of two steps. The first step is groupwise fault isolation. Here, a group of faults is isolated from other possible faults in the system. The group-wise fault isolation is based directly on the input/output signals applied for the fault detection. It is guaranteed th...

The corresponding author Abstract—A multi-layered fault injection mode is explored and a multi-layered system robustness testing strategy based on abnormal parameter is put forward. Fault injection methods for three layers (API, DPI and system calls based on workloads) of Linux operation system are designed. And an integrated fault injection platform to multi-layered fault injection for testing...

The device-level size and complexity of reconfigurable architectures makes fault tolerance an important concern in system design. In this paper, we introduce a fully-automated fault recovery system for networked systems which contain FPGAs. If a fault is detected that can not be addressed locally, fault information is transferred to a reconfiguration server. Following design recompilation to av...

The premise of model-based diagnosis is that the system for diagnosing is diagnosable. Previous methods to diagnose fault are mainly based on the assumption of abrupt change, and under this kind of assumption, unpredictable fault can be caused by those possible slowly changing fault or that the system cannot be diagnosed. Diagnosability of slowly changing fault is discussed in this essay, and t...
