The Signal Extraction and Compression of Engine Rotate Speed of a Certain Type of Chassis

Abstract

For the diesel engine of a certain type of chassis, the key task to be solved in special vehicle technical support is fault diagnosis technology. In terms of fault diagnosis of a diesel engine, fault signal extraction is always needed no matter what methods are adopted. There is no accurate diagnosis decision without an effective extraction method. Aiming at finding fast and effective fault diagnosis to a diesel engine without vehicle disassembly, the authors explore into detection signal during the diagnosis and study extraction and compression of rotating signal in the paper.
