Research on the embedded condition monitoring and fault diagnosis system for the rotation machine

To construct an intelligent machine with self-monitoring and self-diagnosis abilities, the technology for realizing an Internet oriented embedded intelligent condition monitoring and fault diagnosis system with remote monitoring, diagnosis, maintenance and upgrading functions for the rotation machine is introduced systematically. The system is based on the digital signal processor(DSP) and the embedded microcomputer and can measure and store the machine work status, such as the rotate speed and vibration etc. in real time. In the system, the DSP chip is used to do the fault signal processing and feature extraction. The embedded microcomputer with a customized Linux operation system carries out the Internet oriented remote software upgrading and system maintenance. An embedded fault diagnosis software is also designed in the system based on the mobile agent technology which can interconnect with the remote fault diagnosis center to realize cooperative diagnosis. This embedded condition monitoring and fault diagnosis technology can effectively improve the intelligence degree of the fault diagnosis system.
