Crane guide rail detection system

According to the crane guide rail detection system, the light curtain sensor is arranged to obtain the guide rail morphology characteristics of the guide rail surface, whether the guide rail is broken or not can be judged, and the abrasion degree of the guide rail surface is quantitatively evaluated; a correction basis is provided for correcting errors caused by flatness of test data; an angle sensor is arranged and used for detecting the angle values of the crane guide rail detection robot in the X direction, the Y direction and the Z direction when the crane guide rail detection robot runs on a guide rail, the current running state of the crane guide rail detection robot is known based on the angle values, and the vertical height difference in the non-vertical state can be eliminated by adopting a corresponding error elimination method based on the running state; the vibration sensor is arranged and used for detecting inherent vibration information of the crane guide rail detection robot and vibration infor
