The Application of Expert System in Fault Diagnosis of Efflux Cutting Mach
Jiehui Li · World Sci-tech R & D · 2001
In this paper, an expert diagnostic system (EDS) for detecting electrical system faults in a efflux cutting mach is introduced. The expert diagnostic system works in synchronism with the extra high-pressure control system by the handshaking signal line, which can, in real time and on-line, detect and diagnose the stepper motor drive circuit. The 8031 single-chip computer is the center of the expert diagnostic system in which knowledge base is set up by production rules, backward reasoning is made by the breadth-first search and the searching speed is increased by using the parallel search. The executing results of the prototype show that the expert diagnostic system meets all design requirements.
