Acoustic Emission technique is a successful method in machinery condition monitoring and fault diagnosis due to its high sensitivity on locating micro cracks in high frequency domain. A recently developed method is by using artificial intelligence techniques as tools for routine maintenance. This paper presents a review of recent literature in the field of acoustic emission signal analysis through artificial intelligence in machine conditioning monitoring and fault diagnosis. Many different methods have been previously developed on the basis of intelligent systems such as artificial neural network, fuzzy logic system, Genetic Algorithms, and Support Vector Machine. However, the use of Acoustic Emission signal analysis and artificial intelligence techniques for machine condition monitoring and fault diagnosis is still rare. Although many papers have been written in area of artificial intelligence methods, this paper puts emphasis on Acoustic Emission signal analysis and limits the scope to artificial intelligence methods. In the future, the applications of artificial intelligence in machine condition monitoring and fault diagnosis still need more encouragement and attention due to the gap in the literature.

The objective of this research is to develop a web-based approach to remote machine condition monitoring and control enabled by Java technologies and based on publish-subscribe design pattern. On top of a Wise-ShopFloor framework (Web-based integrated sensor-driven e-ShopFloor), this system can serve real-time data from bottom up and can function as a constituent component of e-manufacturing, particularly for web-based collaborative manufacturing. It is designed to use the popular client-server architecture, VCM (view-control-model) design pattern, and publish-subscribe design pattern for secure device control and efficient machine condition monitoring. This paper presents the basis of the developed technology for building a web-based monitoring and control system that can be easily integrated to the e-manufacturing paradigm. A case study of a tripod parallel kinematic machine is carried out to demonstrate the effectiveness and validate our approach to web-based real-time machine condition monitoring and remote control for collaborative manufacturing.
