Abstract

An embodiment of the invention provides a locomotive wheel diameter detection system. The locomotive wheel diameter detection system comprises a controller, a first light ray projector, an image collection device and a processor, wherein first light rays are projected to a locomotive wheel tread by the first light ray projector to form light sectioning curves under the control of the controller; the image collection device collects light sectioning curve images comprising the light sectioning curves; and the processor analyzes the acquired light sectioning curve images with an image segmentation method, and the locomotive wheel diameter is obtained.

Description

Technical field [0001] The invention relates to the field of mechanical detection, in particular to a locomotive wheel diameter detection system. Background technique [0002] The wheel is one of the key components of the locomotive running system. The wheel is the part of the locomotive wheel that contacts the rail. Its main function is to ensure the operation and steering of the locomotive wheel on the rail. During the running of the locomotive, the working status of the locomotive wheels will directly affect the safety of the locomotive. Therefore, the wheels are often used as one of the important parts of the daily maintenance of the locomotive. [0003] The main routine inspections of locomotive wheels include the inspection of the external dimensions of the locomotive wheels and the inspection of the defects of the locomotive wheels. Among them, the inspection of the external dimensions of the locomotive wheels includes the detection of the diameter of the locomotive wheel, t...
