AI Technical Summary
Existing oil pollution detection technologies suffer from problems such as low detection efficiency, potential secondary pollution, insufficient sensitivity to thin oil layers, susceptibility to environmental interference, narrow applicability, and high subjectivity leading to misjudgment.
Based on the characteristic fluorescence generated by oil stains under ultraviolet light excitation, a non-contact detection method is adopted, combined with optical filtering and image processing technology. Through preprocessing, fluorescence excitation, signal acquisition, signal processing, and judgment and analysis steps, the automatic detection of oil stains is achieved.
It achieves efficient, pollution-free, and accurate detection of various industrial oil contaminants, can identify thin oil contaminants with a thickness of more than 0.1 mm, and can distinguish between leaked and residual oil contaminants, providing multi-dimensional information support for equipment maintenance.
