An intelligence diagnostic system for reciprocating machine

A vibration diagnostic system for a reciprocating machine has been developed. Its main function is to monitor operation state and to diagnose faults for the reciprocating machine. The software has two parts, one in a diagnostic machine and the other in a PC. It can perform diagnosis on the spot, realize self learning and adapt to many types of machine. It takes main factor autoregressive model as a character extractor and the ANN model as classifier. With the combination of the two technologies, the system can perform data sampling, signal analysis, character extracting and fault recognition automatically. It reduces factors involved by human beings in a diagnosis process, so the accuracy of the diagnosis and the level of intelligence and automation has been raised.
