Laser monitoring station and laser detection method for online rapid identification of steel number plate

The invention discloses a laser monitoring station and a laser detection method for online rapid identification of steel license plates, and relates to the field of laser detection, the laser monitoring station is simple in structure, a cleaning system of the laser monitoring station can clean a detection spot on a workpiece, then a detection system can perform laser detection on the workpiece with the detection spot, and the detection efficiency is improved. Compared with the mode that the workpiece needs to be detected after being completely cleaned in the prior art, the method has the advantages that the detection process is simpler; in addition, a control system which plays a connecting role between the cleaning system and the detection system can adjust the working distance between the cleaning system and the workpiece and the working distance between the detection system and the workpiece, and meanwhile, the consistency of cleaning and detection is guaranteed; the problems of high error rate, long time
