Functional Allocation and Door Control of ATO for Korean Radio-based Train Control System

초록

The Communication Based Train Control (CBTC) performs train position report immediately and movement authority transmission through wireless communications between a wayside control center and on-board vehicle computers. And it has effect of increasing the railway capacity by allowing the high-density train control through a high capacity of information transmission between the on-board and the wayside. Also, it reduces the maintenance cost because it does not use the existing track circuits. The Automatic Train Protection (ATP)/ Automatic Train Operation (ATO) is fundamental train control system for driverless operation in urban rail and metro rail, and it is important role in the communications based train control system. Especially, the ATO acts as a key role for automatic operation in urban rail with short distance between stations stopping and frequently stops. This paper describes the door control including platform screen door (PSD) and functional allocation of ATO which is responsible for the automatic operation and the door control as a subsystem of the Korean Radio-based Train Control System (KRTCS).
