METHOD OF DIAGNOSING ROLLING STOCK BRAKE MAIN LINE AND DEVICE TO THIS END Russian patent published in 2010 - IPC B60T17/22 G01L19/08 

FIELD: transport.

SUBSTANCE: invention relates to railway transport, particularly to devices designed to diagnose rolling stock brake main line and can be sued to detect faulty spots in braking system. In compliance with proposed method, signals are continuously recorded and stored in signal measurement circuits that contain data on time intervals of arrival of threshold pressure variations in the train head and tail ends arriving to said circuits. Then requested data on request signals are sent to computer to determine car number wherein the air leaks exist using the pre-registered calibration curve. Proposed device comprises first measurement circuit arranged in the train head end and second measurement circuit arranged in the train tail and, and computer. First measurement circuit comprises first pressure controller, first differentiator, first comparator, first radio modem and first recording unit. Second measurement circuit comprises second pressure controller, second differentiator, second comparator, second radio modem and second recording unit. Said recording unit can store data on time of arrival of brake wave from air leak source to train head and tail ends. Computer can generate synchro signal of recording units inquiry.

EFFECT: reliable diagnostics at short-term failure of wireless or wire communication.
