Abstract

Kyung-Bu High Speed Railway is operated in train control system(tcs) of fixed block operated in a way of dividing track circuits into several blocks in accordance with operation circumstances such as rolling stocks, grade, curves and facilities. The TCS of fixed block system refers to a continuous train control system, which transfers operational information such as entry and exit speed, distance-to-go, and deceleration etc. into on-board train control equipment on the basis of block occupancy of a preceding train. It guarantees a safe operation of trains by giving an emergency braking order, in case that a train exceeds an entry and exit speed of a corresponding block. In this paper, we analyze the speed control code deducing in accordance with maximum operation speed and characteristics of rolling stocks by analyzing principles of generation of speed control code allocated in blocks for safe operation, then train operational efficiency was analyzed by means of analysis of operation headway in accordance with the deduced speed control code. This study will be used to design in case of getting an increase in speed for existing high speed line or new high speed line TCS.

경부고속철도는 운영환경(차량,구배,곡선,시설물 등)에 따라 궤도회로를 여러 개의폐색으로 분할하여 운행하는 고정폐색방식의 열차제어시스템으로 운행된다. 고정폐색방식 열차제어시스템은 선행열차의 점유폐색을 기준으로 진입/진출폐색속도, 목표거리, 감속도와 같은 운행정보를 차상열차제어장치로 전송하여 연속적으로 열차를 제어하는 방식으로, 경부고속철도 열차제어시스템은 열차가 해당 폐색의 진입/진출속도를 초과할 경우, 비상제동명령을 내려 열차의 안전한 운행을 보장한다. 본 논문에서는 안전한 운행을 위해 폐색에 할당되는 속도제어코드의 생성원리를 분석하여, 최고운행속도와 운행차량특성에 따른 속도제어코드를 도출하고, 도출된 속도제어코드에 따른 운행시격 분석을 통해 열차 운행효율을 분석하였다. 이와 같은 연구는 기존 고속철도의 증속 및 신규 고속철도 열차제어시스템 설계 자료로 활용될 수 있다.
