| Abstract: | In order to solve the "slip_error" of wheel tachometer the paper presents a new method of non_contact measurement of rail speed by eddy current sensors. Two eddy current sensors, which are mounted on bogie frame of the vehicle, can detect stochastic inhomogeneity in region of the rail. From two signals the vehicle speed and distance of travel are gained by means of a digital transit_time correlator. The principle of signal processing of eddy current sensors and a simulate test device are illustrated. The experimental research has obtained satisfactory result. Therefore it is a new way to raise measurement accuracy of speed. |
