SAFETY UNIT Russian patent published in 2012 - IPC B60L15/20 B61L27/00 

FIELD: transport.

SUBSTANCE: invention relates to railway automation and telemetry systems and may be used in railway safety systems. Locomotive safety control unit comprises accelerometer and processor connected in series. Processor generates control signal and indication signals in emergency. For this it is provided with extra data buses for locomotive control instructions and limitation of motion parameters and their current values as well as control output of warning circuit. Accelerometer is rigidly secured on processor base. Besides, said processor may generate indication signals for engineman, securities and dispatcher while processor signaling circuit output is made up of three appropriate signal buses. Also, processor generates signal to control engine, brakes and door opening mechanism while processor control circuit output is made up of three appropriate control buses._< Processor may generate braking and emergent braking while appropriate control bus is made up of brakes control bus and emergent braking bus. Said processor comprises subtractor, adder, four comparators, two AND element, delay unit and OR element.

EFFECT: expanded operating performances, higher reliability and validity, higher safety.
