METHOD OF OPERATING ELECTRO PNEUMATIC BRAKE AND DEVICE TO THIS EFFECT Russian patent published in 2010 - IPC B60T17/22 B60T7/12 

FIELD: transport.

SUBSTANCE: special switch is additionally included in brake electric control circuit. Electro pneumatic brake comprises, apart from standard automatic control devices, a modernised control unit with power supply. Control and operating DC power supply sources of supply unit are galvanically isolated and separated from locomotive storage battery. Rolling stock cars or platforms are equipped with braking pickups and additional sealing-off head with built-in semiconductor diode. Control unit operation algorithm controls normalised operating conditions of electrically-driven air control valves and generates continuous alternation of DC forward-and-back-polarity pulses to be sent into train circuit from control power supply. This allows identifying both serviceability of trains circuit and braked units of the train. Aforesaid special switch allows braking electric power supply circuits of locomotive operator brake valve and appropriate light signaling device lamp. As a result, in electro pneumatic braking it becomes possible to identify braked train units.

EFFECT: possibility to control braking processes in electro pneumatic and pneumatic control of brakes.
