Functions and Characteristics of Door Control Unit for EMU

초록

We have been developed electric plug-in door. The door is controlled by Door Control Unit(DCU) following the order of Automatic Train Protection (ATP) that is a kind of train signalling system. DCU has to simultaneously open and close the doors and the operation of it is related to the passengers safety. So the DCU is a safety device that is important to reliability and safety. DCU is composed of several devices for control, motor driving, Input/Output, communication and power. This paper describes the functions, characteristic, requirement, and subsystem of DCU used for the electric plug-in door.
