COMPLEX CONTROL SYSTEM FOR DC ELECTRIC LOCOMOTIVES Russian patent published in 2010 - IPC B60L15/36 

FIELD: transport.

SUBSTANCE: invention relates to railroad ACS for DC electric locomotives. Proposed complex system comprises operating conditions controller with its outputs connected to the boards of the main and auxiliary controllers. The latter have their outputs connected to inputs of the main and auxiliary control cipherers. Outputs of cipherers are connected, via first switchboard controlled by operating conditions controller, to second switchboard. One of outputs of switchboard is connected with forward telecontrol communication line, while another one is connected with the rearward telecontrol communication line. Signal is fed, via communication lines, to inputs of the main or emergency telecontrol code cipherers with their outputs connected with logical elements OR. Signal from said elements is fed to locomotive actuator. Outputs of all controllers are isolated from inputs of the main and emergency control cipherers and first switchboard. Output of switchboard and inputs of the main and emergency telecontrol code cipherers are isolated from forward and rearward telecontrol communication lines.

EFFECT: higher reliability.
