Abstract

The invention discloses a three-dimensional digital particle image generation device and method based on excitation adsorption. In the device, the imaging module and the adsorption module are arranged on the same side of the light-transmitting sheet, the light-transmitting sheet is arranged on the upper surface of the flow channel, and the light-transmitting sheet is located on the imaging module. In the center of the optical path and the magnetic field generated after the adsorption module is powered on, the adsorption module adsorbs the particles to the bottom of the light-transmitting sheet; the imaging module is equipped with a focusing mechanism for adjusting the focal length to obtain images of different focal planes; Different differential operators and wavelet image processing are used to divide the focal plane range, and the morphological processing method is used to measure the three-dimensional surface of magnetic particles, and through Boolean algebra operations, different focal plane images are superimposed and reconstructed into a new particle image. The invention adsorbs particles on the same plane through an adsorption module, obtains images of different focal planes for synthesis processing, and generates clear and stable three-dimensional digital particle images.

Description

technical field [0001] The invention relates to a technology for analyzing and judging the operating state of mechanical equipment by detecting magnetic particles in a fluid, in particular to a three-dimensional digital particle image generation device and method based on excitation adsorption. Background technique [0002] Generally speaking, the commonly used technology for online monitoring and analysis to judge the lubrication and wear state of equipment is ferrographic oil monitoring technology. Ferrographic oil monitoring technology appeared in the 1970s. Through the deposition and analysis of ferromagnetic particles in the lubricating oil in use, the operating status and wear trend of the equipment are monitored, the wear mechanism is judged, and the early failure prevention of the equipment is realized and the failure is reduced. It has the advantages of stable performance, reliability, and strong anti-interference ability. [0003] Ferrography oil monitoring techno...
