Abstract

The invention relates to the technical field of hydraulic system part defect detection, in particular to a hydraulic gear pump defect detection method and system based on artificial intelligence. The method comprises the following steps: acquiring a tooth surface target area of a gear pump image; obtaining the complexity of the target area; obtaining the entropy of the target area under each color channel, obtaining a spatial distribution vector according to the entropy of the target area, and obtaining an abnormal index according to the difference between the spatial distribution vector and the spatial distribution vector of the normal tooth surface; obtaining the difference degree between any two pixel points in the target area, and obtaining the difference index of the target area according to the difference between the difference degree and the difference degree of the normal tooth surface; and obtaining a defect confidence coefficient according to the complexity, the abnormal index and the difference index, and determining that the gear pump has defects when the defect confidence coefficient is greater than a preset threshold value. The target area is comprehensively considered from multiple aspects, different characteristic parameters are obtained, and the accuracy of tooth surface defect detection is improved.

Description

technical field [0001] The invention relates to the technical field of defect detection of hydraulic system parts, in particular to a method and system for detecting defects of hydraulic gear pumps based on artificial intelligence. Background technique [0002] With the development of automation in modern industrial enterprises, the hydraulic equipment in various industrial enterprises is also rising. In order to ensure the normal and efficient operation of hydraulic equipment, it is usually necessary to test the components and parts of hydraulic equipment in the actual application process. Repair and maintenance. The gear pump is the power component of the hydraulic system. The gear is an important transmission part commonly used in hydraulic equipment. The quality and precision of the tooth surface have an important impact on the overall performance and service life of the entire hydraulic equipment. [0003] Most of the existing fault detection of gear pumps in hydraulic...
