Remote Monitoring & Diagnosis of Breaking-Down Fault for FDM Rapid Prototyping Machine

To solve the problem of remote diagnosing faults for high-automatic long-period minute machines in their running period, the VPON remote monitoring system and image processing technology are used to carry out the remote diagnosis of FDM rapid prototyping machine breaking-down fault. This paper emphasizes on the introduction of the research environment and construction of tools and system. The decision methods of several key thresholds are also analyzed in the course of fault recognizing.
