DETECTING DEFECTIVE CONDITIONS IN RAILWAY VEHICLE WHEELS AND RAILTRACKS

摘要

A mobile tracking unit capable of detecting defective conditions associated with a set of railway vehicle wheels and with a railtrack upon which a given railway vehicle travels comprises a rotation measurement unit (80) for generating data indicative of rotational rate of the set of wheels; a motion sensor (56), such as an accelerometer or vibration sensor, for generating data indicative of motion along a vertical axis relative to the railtrack; a data processor (70) coupled to the motion sensor and to the rotation measurement unit for receiving the rotational rate and motion data; a navigation set (50) for generating data corresponding to a respective railway vehicle position thereby allowing for determination of the location at which any respective defective condition occurs; and a transmitter (52) for transmitting predetermined data associated with the railway vehicle to a remote location where the transmitted data can be processed.
