Abstract

The invention discloses an axial vibration and rotating speed synchronous monitoring method and system, and the method comprises the steps: carrying out the complexity analysis of a first collection angle and a first collection environment, and obtaining a first complex index; judging whether the first complex index is in a preset complex index threshold value or not; if yes, obtaining a first preset marking rule; according to the first preset marking rule, obtaining a first preset marking line and a second preset marking line; based on a first image acquisition device, obtaining a corresponding first linear array image and a second linear array image; and performing edge feature extraction on the first linear array image and the second linear array image through an edge recognition algorithm to obtain a first extraction signal and a second extraction signal, thereby obtaining first synchronous monitoring data. The technical problems that in the prior art, accurate synchronous monitoring of axial vibration and rotating speed cannot be achieved through a monitoring mode based on a sensor, signal interference influences are large, and adaptability to complex working conditions is not high are solved.

Description

technical field [0001] The invention relates to the related field of industrial machinery, in particular to a method and system for synchronous monitoring of axial vibration and rotational speed. Background technique [0002] With the development of my country's economy and science and technology, various fields in our country are undergoing relatively rapid reforms, and the high-quality and efficient completion of industrial machinery has great research value. The vibration signal of industrial machinery contains a wealth of equipment information. The axial vibration of rotating machinery can often reflect the installation accuracy and operation safety of the equipment. For example, problems such as equipment misalignment and mass eccentricity can be reflected in the axial vibration. In the signal, the machine needs to have precise control of the position and speed when it is working. If the control is not accurate enough, it will easily cause the work content to deviate an...
