Abstract

The invention discloses a subway vehicle bearing fault online detection method, and belongs to the field of subway safety monitoring. The key point of the technical scheme comprises the following steps: (1) establishing a model: the establishment of a bearing fault model is the basis for fault identification; (2) fault diagnosis: collecting and diagnosing vehicle bearing information of the vehicle; and (3) form a report and uploading the report: form the reporting of comparative judgment results, and uploading the report. By adopting the subway vehicle bearing fault online detection method disclosed by the invention, the problem that a bearing fault cannot be found in time is solved, and effects of founding the bearing fault in advance and replacing or maintaining the faulty bearing in time are realized.

Description

technical field [0001] The invention relates to the field of subway safety monitoring, more specifically, it relates to an online fault detection method for subway vehicle bearings. Background technique [0002] As a modern transportation tool, the safety of subway operation is very important. With the increase of speed, the density of trains will increase the pressure on the safe operation of subways. Bearing failure is one of the main sources of failure in train operation, and it is also the biggest factor affecting safety. [0003] The current conventional method is to regularly overhaul the bearings, but this method cannot detect bearing failures in time, causing the faulty bearings to continue to be used, posing safety hazards, and frequent overhauls can easily lead to over-maintenance and reduce the failure rate of bearings. and maintenance costs. Contents of the invention [0004] In view of the deficiencies in the prior art, the purpose of the present invention is...
