The invention provides a vibration data processing method and system, model training method and system and detection method and system of lifting equipment. The processing method comprises the steps that vibration data generated in the operation process of the fixed lifting equipment are obtained through a vibration sensor; and target data are obtained, the target data are constant-speed segment data obtained by segmenting and extracting the vibration data according to the operation state of the fixed lifting equipment, and the constant-speed segment data are vibration data generated when the fixed lifting equipment is in the constant-speed operation state. According to the methods and systems, the constant-speed segment data capable of accurately reflecting the operation state of the fixed lifting equipment are obtained, a health state evaluation model and a fault diagnosis model are obtained based on training of the constant-speed segment data, the detection result is obtained through the two models, detection data are varied, the diagnosis range is comprehensive, the fault judgment accuracy is improved, the actual situation is met, before a shutdown fault occurs, the abnormal state can be detected, the fault type can be discriminated, maintenance personnel can arrange maintenance strategies conveniently, and the shutdown fault is avoided.
