The application discloses a kind of high-speed camera detection multi-
machine drive
system synchronous
phase difference measurement method, it is related to vibrating screen
synchronous detection technical field, and the device used includes vibrating screen prototype, high-speed camera, camera support,
data processing software and positioning sheet etc..First, high-speed camera is installed with the
plane parallel of vibrating screen motor rotor, and
image sequence in the rotating process of rotor is collected;Second, the pixel coordinates of positioning sheet and rotating center are obtained by image recognition technology, and relative position vector is constructed. Through interpolation
noise reduction
processing to vector coordinates, project to preset
reference vector, generate projection coordinate-
time curve, and extract image
phase difference. Finally, according to the rotating direction of motor, image
phase difference is converted into motor phase difference using unified formula, and accurate measurement under multiple working conditions is realized. The method solves the industry pain point that positive and
negative phase difference measurement standards are not unified, and the
measurement precision is high, which can be popularized to multiple working condition detection scenes of multi-
machine drive rotating equipment.
