TRAIN BRAKE SYSTEM MONITORING DEVICE Russian patent published in 2005 - IPC

FIELD: railway transport.

SUBSTANCE: invention is designed for checking condition of pneumatic systems of locomotive, cars and train. Pressure differential pickup in main reservoirs of locomotive is provided with relay-repeater with change-over contains, and meter of time of reduction of pressure by value differential, in form of time interval setter connected by output through contact of relay-repeater to pulse counter. Normalized air rate setter is connected to divider. One group of change-over contacts of said relay-repeater is coupled with pulse counter to provide separate counting of pulses of duration of pressure reduction and rise in main reservoirs according to operation of compressor, and second group of contacts is coupled with divider with possibility of its connection in turn to digital indicators of compressor tightness and capacity. Fixed tightness index storage unit with element to compare said index with current measurement result is connected to pulse counter. Output of storage unit is connected with digital indicator.

EFFECT: improved safety of traffic owing to automation of monitoring of condition of pneumatic system and compressor plant.
