DGY470A型内燃调车机车主要为地铁列车提供牵引、调车及救援。论述了该型内燃调车机车的电气控制系统,采用GWCY044-B型微机控制器及信号发生器进行软件编程,完成内燃调车机车的柴油机调速、换向及换挡等走行功能。同时利用该控制系统,最终实现了具有双机重联功能的内燃调车机车电气控制系统。
DGY470A diesel shunting locomotive mainly provides traction, shunting and rescue for subway trains. The electrical control system of this type of diesel shunting locomotive is discussed. The software of GWCY044-B microcomputer controller and signal generator is used to program the running functions of diesel shifter, reversing and shifting of diesel shunting locomotive. At the same time, with the control system, the electric control system of diesel shunting locomotive with double-machine reconnection function is finally realized.
