Embodiment Construction
[0065] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.
[0066] The method of this embodiment is as follows:
[0067] The embodiment of the invention is for fault bearing location during train operation. The 36 temperature sensors on the train correspond to 36 important positions, and the 36 temperature sensors are used to monitor the working status of the train bearings. It contains 4 bearings, each bearing has 7 temperature sensors (small gearbox motor side, small gearbox wheel side, large gearbox motor side, large gearbox wheel side, motor stator, motor drive end, motor non-drive end ). Also included are 8 axle boxes, each with a temperature sensor, for a total of 36 sensors. In the collected train bearing temperature dat...
