[0003] At present, the detection of the thickness of subway brake shoes in China mainly relies on the experience of maintenance personnel. Maintenance personnel measure the thickness of subway brake shoes by visual inspection combined with a ruler. This method has the following deficiencies: 1. The inspection of brake shoes is an under-vehicle operation, and maintenance personnel need to conduct inspections in the train pit. However, the lighting in the train pit is not bright enough, especially the brake shoes on the upper side of the motor bogie are completely blocked by the motor and are almost completely dark. Maintenance personnel need to use a flashlight to increase the brightness to complete the measurement and inspection. 2. Due to the motor blocking the upper side of the motor bogie, the space available for maintenance personnel to operate is very limited. Maintenance personnel can only barely place the ruler in the measurement position, but when reading the data, since the scale line of the ruler is completely blocked by the hand, maintenance personnel cannot complete the measurement and reading of the data.
