TRACTION ROLLING STOCK CONTROL AND SAFETY SYSTEM Russian patent published in 2011 - IPC B61L3/00 B61L27/00 B61K3/02 

FIELD: transport.

SUBSTANCE: proposed system comprises safety subsystems, service braking and train automatic control subsystem, separate functional units including onboard radio transceivers, locomotive signaling and satellite navigation receivers, track and speed pickups, locomotive equipment fault detectors, locomotive pneumatic braking system pressure pickups, engineman wakefulness control unit, interactive data display, essential data manual input device, and data register with nonvolatile memory. Subsystems and functional units are interconnected via system CAN-interface. Every subsystem in provided with route electronic card and electronic data base comprises thresholds of tolerable speed by motion coordinate. Locomotive wheel flange lubricator control unit is connected on CAN-interface and, via separate input and digital communication line, with output of vibro acoustic signal processing unit, said vibro acoustic signals being emitted at points of mechanical interaction between locomotive wheels and rails. Coordinates of track sections to be lubricated are entered into route electronic card. Electronic data base of safety subsystem, automatic braking control subsystem and train automatic control subsystem comprises data on said track sections intended for selecting wheel flange lubrication control modes at preset combinations of rolling stock motion and expected amplitude time-and-frequency characteristics of processed vibro acoustic signals.

EFFECT: higher safety.
