A Web-based on-line Monitoring and Diagnosis System for Machinery of Hot Strip Mill

Abstract

A multi-agent based on-line monitoring and diagnosis system (MAMDS) is developed for distributed measuring, monitoring and diagnosis machines of a hot strip mill in the China Steel Corporation. MAMDS takes the advantage of Web-based properties, it releases the restrictions of temporal and regional isolation and provides a platform-independent user interface. Through the system, users can easily monitor and diagnose the machines on remote production lines through its graphical user interfaces, such as display of machine status, malfunction alarming, trend chart, waveform, and spectrum. It uses collaborative agents to reduce the cost of development and enhance the feature of reuse. The system provides a real-time and dynamical operation circumstance and can meet the needs of different levels of users. Consequently, it is of great help to run machines smoothly, lower the cost of personnel and enhance the ability of market competition.
