Background Art

[0002] During the maintenance process of railway vehicle wheel pairs, the existing wheel pair maintenance process requires workers to manually push the wheel pairs to roll on the maintenance line and complete the maintenance through various automated maintenance equipment. However, this method leads to an increase in the auxiliary time for maintenance, a decrease in maintenance efficiency, and an increase in the labor intensity of workers. Therefore, it is necessary to introduce more advanced automated maintenance equipment and digital technologies to improve efficiency and reduce the labor intensity of workers.
