MULTI-SECTION DIESEL LOCOMOTIVE CONTROL SYSTEM Russian patent published in 2015 - IPC B60L15/32 B61C17/12 

FIELD: transport.

SUBSTANCE: proposed system comprises engineman control board with display module, engineman controller with motion mode selector, actuators and remote control system including programmable controller and standard logical elements. Programmable controller is connected via discrete signal with engineman controller, motion mode selector and actuators auxiliary contacts, via discrete signal output devices with inputs of actuators, via mounted axle rpm frequency signal input devices mounted axle rpm transducers, via analogue signal devices with transducers with analogue output, via temperature parameter input device with temperature pickup outputs, via thyristor inverter control signal output device with thyristor inverter control inputs. Programmable controller is also connected via multichannel communication unit with display module and with multichannel communication units of all locomotive sections via communication CAN 2.0V protocol-based channel. For transmission of control data, multichannel communication units of different sections via communication channel built around ETHERNET network protocol.

EFFECT: higher reliability of locomotive control system, unified and simplified control circuit.
