Improved Bayesian network-based for fault diagnosis of air conditioner system

Remote management of LonWorks based control system for air conditioner

In this paper, we describe implementation and test result for a LonWorks based control system in which air conditioner is handled by LonWorks node. The LonWorks based control system for handling air conditioner remotely is integration of control nodes because LonWorks is a communication protocol which is adopted as a standard protocol in building automation systems. For the remote management of...

Fault Diagnosis of Motor Bearing Based on the Bayesian Network

On the basis of the analysis of vibration characteristics of motor bearing faults and the influence from testing noise on site, calculation of the symptom parameters representing the vibration signals according to the measured vibration signals is proposed, and the sensitivity analysis is carried out to these parameters which can refine effective symptom parameters. As there are limitations for...

Fault Identification in Fuel Cells Based on Bayesian Network Diagnosis

This paper considers the effects of different types of faults on a model of a proton exchange membrane fuel cell (PEMFC). Using databases (which record the effects of the faults) and probabilistic methods (such as the Bayesian-Score and Markov Chain Monte Carlo), a graphical-probabilistic model for fault diagnosis is constructed. The graphical structure defines the cause-effect relationship amo...

Self Training of a Fault-Free Model for Residential Air Conditioner Fault Detection and Diagnostics

A Fuzzy Rule Based System for Fault Diagnosis, Using Oil Analysis Results

    Condition Monitoring,   Oil Analysis, Wear Behavior,   Fuzzy Rule Based System   Maintenance , as a support function, plays an important role in manufacturing companies and operational organizations. In this paper, fuzzy rules used to interpret linguistic variables for determination of priorities. Using this approach, such verbal expressions, which cannot be explicitly analyzed or statistic...
