METHOD OF CONTROLLING ELECTROPNEUMATIC BRAKE Russian patent published in 2011 - IPC B60T17/22 B60T7/12 G01L5/28 G01M17/07 

FIELD: transport.

SUBSTANCE: invention relates to railroad transport and may be used in electropneumatic brakes of passenger trains. Proposed method consists in that extra head of final termination provided with standard solid-state diode, pressure signaliser and extra solid-state diode is mounted on free head of tail car brake line connecting hose to open its end valve thereafter. Pressure signaliser is set to operate at compressed air pressure predefined with due allowance for signaliser error by tolerable compressed air pressure difference between head and tail cars brake lines. Said standard solid-state diode is connected to make contact in direction from control wire of train line to its working wire while extra solid-stage diode is connected to pressure signaliser break contact in direction from train line working wire to its control wire.

EFFECT: possibility to exploit electric current frequency characteristic to allow simultaneous braking and to annunciate locomotive engineman about emergency conditions.
