Abstract

The embodiment of the invention provides a mechanical equipment fault early warning method and system based on a vibration signal, and the method comprises the steps: extracting vibration acceleration data, vibration speed time domain data and vibration displacement time domain data through the vibration signal, and carrying out the time domain analysis of the vibration acceleration data, the vibration speed time domain data and the vibration displacement time domain data; and obtaining the time domain indexes changing along with time in the vibration signals, and taking the time domain indexes as fault feature data for fault early warning so that the vibration signals of the mechanical equipment can be analyzed more deeply, and then fault early warning can be carried out at the initial stage of fault occurrence.

Description

Technical field [0001] Embodiments of the present invention relate to fault warning techniques, and more particularly to a mechanical equipment fault warning method and system based on a vibration signal. Background technique [0002] As the modernization of enterprise equipment management, how to operate the equipment continuous, reliable, safe and efficiently to adapt to the requirements of modern enterprise management, is especially important. The modern industry is characterized by large production equipment, continuous, high speed and automation. It has great advantages in increasing productivity, reduces cost, saving energy and manpower, reducing waste rate, ensuring product quality, but due to the loss of damage and maintenance costs due to failure of mechanical equipment. Many developed countries have a lot of blood lessons and huge costs before fault diagnosis technology has not yet formed. At present, many companies are still in the stage of planned maintenance system, ...
