열차 자율주행을 위한 차상중심 분산형 연동시스템

Autonomous train driving system is an intelligent train control system capable of unmanned train operation via a direct communication between trains or train and trackside apparatus instead of relying on control command from the ground control systems such as, wayside ATP and interlocking system. The existing interlocking system in wayside-centric train control system distributes shared resources, track and switches to all trains within the coverage area based on the occupancy of the train. However, allocation of resources to track is the overlap with the function of ATP. In this paper, we propose the new train-centric distributed interlocking system for autonomous train driving system. The proposed distributed interlocking system newly defines the semaphore scheme using a unique key value for the shared resource, switch to be not accessed at the same time by interlocking system within each train. We present a safe train control is possible by comparing for the proposed distributed interlocking system to the number of interlocking logic based on existing interlocking system.
