Mechanical equipment fault type automatic diagnosis method and system

Abstract

The invention discloses a mechanical equipment fault type automatic diagnosis method and system. The method comprises the steps that the type of tested equipment is determined; a set equipment template is selected according to the type of the tested equipment, wherein the equipment template includes template information, and the template information includes the equipment type, measurement position information, measurement definition information and threshold information; the characteristic frequency of different measurement positions of the tested equipment is calculated according to the equipment template; a standard fault spectrogram is generated according to the characteristic frequency; and the standard fault spectrogram and the actual fault spectrogram are compared, and the fault type of the tested equipment is automatically analyzed. With application of the diagnosis method and system, the measurement information can be automatically determined before testing the tested equipment so that the measurement factor determination process can be simplified, fault type diagnosis of the tested equipment can be automatically performed in the measurement process and the diagnosis efficiency can be enhanced.

Description

technical field [0001] The invention relates to the field of mechanical equipment fault diagnosis, in particular to an automatic diagnosis method and system for mechanical equipment fault types. Background technique [0002] With the rapid development of modern industry, various machinery and equipment are widely used in various industrial fields. The normal operation of the equipment is related to the safe and efficient long-term operation of the equipment, and it is also an important guarantee for the normal production of the entire enterprise. Therefore, equipment detection and fault diagnosis play a vital role. Through equipment detection and fault diagnosis, equipment problems can be detected early to avoid accidental downtime of mechanical equipment, thereby reducing downtime losses and improving personnel's operating safety. [0003] The traditional equipment measurement and diagnostic analysis method is: use a dedicated vibration collector to connect with the sensor...
