Automated Stand for Magnetic Luminescent Control of Railway Wheels
The amount of information processed and time constraints required the creation of a multi-level distributed image processing system based on National Instruments Compact Vision System controllers, industrial computers and workstations. During the control process, the wheel is watered with a magnetic-luminescent emulsion, magnetized and exposed to ultraviolet radiation. As a result, the emulsion deposited on the defects glows in the visible range (yellow-green light). Eleven FireWire (IEEE 1394) color cameras with a resolution of 1280 x 1024 are used to scan the wheel surface. In one iteration, they completely cover a 20-degree sector of the wheel.
