RMG rail-biting fault diagnosis method based on multi-sensor data amalgamation technology

The invention belongs to the field of rail type hoisting equipment and rail locomotives, and relates to data processing and rail biting fault diagnosis technologies. According to the principle that various causes of rail biting can be explained by following a certain pattern, a range acquisition sensor, a gray bus, a rotary encoder and other sensors are utilized for obtaining the information about rail biting; a list of possible causes for rail biting can be formulated following a series of operations such as the pretreatment, the multi-sensor data integration technology, the fault diagnosis logical operation and the like; and the case of RMG biting rail is displayed in the form of graphics, or the causes for rail biting are reported to police in writing. The method finds the root causes of rail biting, thereby not only greatly reducing or eliminating the phenomenon of rail biting but also helping maintenance personnel master the condition of the equipment. The integration of the multi-sensor data enables the
