Electric Control System of DGY470A Type Diesel Shunting Locomotives

Abstract

DGY470A type diesel shunting locomotives are mainly used for metro vehicle traction, shunting and rescuing. The electric control system of the locomotive was introduced, which adopted GWCY044-B microcomputer controller and signal generator for software programing to complement the diesel engine running functions such as speed regulation, commutation and shifting etc. Based on the control system, the diesel shunting locomotive electric control system with double-unit reconnection function was realized.
