Description

technical field [0001] The invention relates to the technical field of information fusion processing, in particular to a computer-aided technology-based method and system for counting oil abrasive particles. Background technique [0002] As the degree of automation of industrial production increases, the connection between the various parts of the equipment becomes closer, and the transmission part will inevitably wear and tear due to relative movement and friction. Today's mechanical equipment often has the characteristics of high precision and high speed, but this will bring the hazards of accelerated wear. With the increase of working time and workload, the degree of wear and tear will also increase significantly. If it is not maintained in time, it will cause damage or even failure of the entire machine, affect production efficiency, cause economic losses, and even threaten the safety of staff. Mechanical equipment must use lubricating oil to lubricate high-speed rotati...

Problems solved by technology

The sensor is placed in the oil pipeline. When abrasive impurities in the oil enter the excitation coil at one end, the magnetic field in the coil will be disturbed. The change of the magnetic field strength will cause the induction coil to generate a positive or negative phase-like sine wave signal. By measuring The waveform signal is used to analyze the abrasive particles in the oil, but the analysis is not accurate. It cannot quantitatively analyze the properties of the abrasive particles in the oil, and cannot accurately classify and count the abrasive particles in the oil.
