The invention discloses an elevator traction wheel rope groove abrasion detection method and system, and relates to the technical field of abrasion detection, and the method comprises the steps: collecting a plurality of groups of rope groove images of a traction wheel; the method comprises the following steps: constructing a feature extraction network model based on a traction sheave rope groove contour standard image, and extracting wear regions of multiple groups of rope groove images through a ResNeXt + feature pyramid network and a non-maximum suppression algorithm; contour points of rope groove abrasion in the abrasion area are extracted, and the abrasion area is fitted into an ellipse based on the contour points; and the abrasion area obtained after fitting is converted into abrasion loss, and the abrasion degree of the elevator traction sheave rope groove is detected through the abrasion loss. According to the method, the abrasion degree of the elevator traction sheave rope groove is accurately detected and quantified, the abrasion degree is judged according to the abrasion loss, maintenance measures are further implemented, and safe and reliable operation of elevator equipment is ensured.

    本发明公开了一种电梯曳引轮绳槽磨损检测方法及系统,涉及磨损检测技术领域,包括:采集曳引轮的多组绳槽图像;基于曳引轮绳槽轮廓标准图像,构建特征提取网络模型,通过ResNeXt+特征金字塔网络和非极大值抑制算法提取多组绳槽图像的磨损区域;提取磨损区域中绳槽磨损的轮廓点,基于轮廓点,将磨损区域拟合为椭圆;将拟合后得到的磨损区域转换为磨损量,通过磨损量检测电梯曳引轮绳槽磨损程度。本发明实现了对电梯曳引轮绳槽的磨损程度进行准确检测和量化,并根据磨损量判断磨损程度,进一步实施维护和保养措施,确保电梯设备的安全和可靠运行。
