Abstract
In one aspect, a mobile railway asset monitoring apparatus is provided that includes a sensor configured to produce a signal indicative of a rotation of a wheelset of a mobile railway asset. The apparatus further includes a processor to receive data corresponding to a ground speed of the mobile railway asset. The processor is operably coupled to the sensor, the processor configured to estimate a running dimension of the wheelset based at least in part on the rotation of the wheelset and the ground speed of the mobile railway asset. The processor is configured to determine at least one parameter of the mobile railway asset based at least in part on the running dimension of the wheelset.
Claims95
A mobile railway asset monitoring apparatus comprising:
- a sensor configured to produce a signal indicative of a rotation of a wheelset of a mobile railway asset as the mobile railway asset moves along a track;
- a processor to receive data corresponding to a ground speed of the mobile railway asset;
- the processor operably coupled to the sensor and configured to calculate a running dimension of the wheelset, the calculated running dimension of the wheelset increasing and decreasing as tapered running surfaces of the wheelset shift laterally relative to rails of the track, the processor configured to calculate the running dimension of the wheelset based at least in part on the rotation of the wheelset and the ground speed of the mobile railway asset;
- and
- the processor is configured to determine at least one parameter of the mobile railway asset based at least in part on the running dimension of the wheelset.
