Abstract

The invention discloses a three-dimensional digital particle image generation device and a three-dimensional digital particle image generation method based on excitation suction. An imaging module and a sucking module of the device are arranged on the same side of a light-transmitting piece. The light-transmitting piece is arranged on the upper surface of a flow pass and is positioned in a magnetic field generated after electrification of the center of a light path of the imaging module and the sucking module. The sucking module sucks particles to the lower side of the light-transmitting piece. The imaging module is provided with a focusing mechanism used for adjusting focus to acquire images with different focal planes. An image processing module is used for dividing focal plane ranges of the images with the different focal planes through different difference operators and wavelet image processing, measuring three-dimensional surfaces of magnetic particles according to a morphological processing method and overlapping the images with the different focal planes through Boolean algebra operation to recreate a new particle image. The particles are sucked on the same plane by the sucking module, the images with the different focal planes are acquired to be synthesized, and the clear and stable three-dimensional digital particle image is generated.

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...
