Document Type and Number:
WIPO Patent Application WO/2019/119496
Kind Code:
A1
Abstract:
Disclosed is a train axle speed control device, comprising: a pressure control valve (10) adjusting a braking cylinder pressure according to an initial braking cylinder pressure control signal to obtain a processed braking cylinder pressure; a transfer pipeline (20) transferring the processed braking cylinder pressure; a braking cylinder pressure detection apparatus (21) collecting and sending a genuine gas pressure value of flowing compressed gas; an axle rotational speed detection apparatus (51) collecting and sending rotational speed information of a train axle (50); and an information processing device (60) analysing whether the rotational speed information and actual gas pressure value received under the initial braking cylinder pressure control signal comply with a pre-set correlation and, if they do not comply, generating and sending a new braking pressure control signal to the pressure control valve (10). The present device makes the locating of reasons for an accident more accurate, and the regulation of axle speed more accurate, while also reducing regulation time, and increasing travelling comfort of passengers. Further disclosed is a train provided with the train axle speed control device, having the benefits and effects above.
