Abstract

An accident recalling system has been applied successfully in the Linyuan refine oil work as part of a rotating machine vibration state monitoring and fault diagnosis system, which consists of vibration preprocessor, comparator and plus generator. The system gives the CPU of vibration state monitoring and fault diagnose system an interupt plus when the vibration amplitude exceeds a dangerous level to enable it to sample and store the vibration data and gets the accident data timely because the interval between the happening of accident and the beginning of sampling is shorter than 1 ms.
