무인자동운전으로 운행되는 경량전철시스템을 시험선에 구축함에 무선통신을 기반으로 하는 신호 제어시스템의 시험평가내용을 정의하였다. 특히 자동열차제어를 담당하는 장치의 시험평가를 길이있게 다루었다. ATO컴퓨터의 시험평가에는 정차시험 및 역구내용주행시험으로 구분하여 시험종류 및 방법을 기술하였다. CBTC역컴퓨터에 대해서는 시스템구축에서부터 안전성 가용률평가까지의 시험절차 및 이에 필요한 평가설비구성을 논하였다.

For trains to run safely and quickly, the train should always follow the preceding train at a proper spacing. For this purpose, a certain distance between the stations is set for each block section. For the safe operation of trains in one block section, only one train service for an automatic block system is needed. The existing block system is composed an ABS, which is a linked track circuit and line sideway system through the interlocking system. The interlocking system is being replaced with a domestic electronic interlocking system. On the other hand, the block system still uses the relay format of an analog system, and is independently installed of the line sideway systems. Therefore, the existing block system has many problems in terms of construction and maintenance. In addition, the existing domestic line is used for ABS and LEU , which is installed separately, despite the train being controlled by the information of the same signal at the same location. This is not efficient in terms of each product price and the maintenance costs. This paper introduces an integrated electronic block system and the field test results. The field test was carried out through a periodic inspection performed eight times from January to late August.

현재의 철도, 도로망 등의 각 중심측 및 간선측의 주요 교통시설은 이미 포화 상태가 되어 물류비용의 증가를 초래하고, 배기 가스를 비롯한 환경오염 문제를 유발하고 있기 때문에 이에 대한 해결방안이 시급한 실정이다. 이러한 상황에서 고속전철은 대기 오염을 일으키지 않으면서 신속$.$대량 수송이 가능하여 교통량을 대량으로 흡수할 수 있는 주요 교통 수단으로 인식되고 있다.(중략)

In this paper, operation mode of train was divided into powering, coasting, and braking and rail wear phenomenon has been done comparative analysis by each section. Data of train velocity is transferred to acceleration and deceleration from ATO Logging data. Amount of rail wear has been done comparative analysis by traction force of acceleration and braking force of deceleration and a plan for management of track irregularity is come up with by the result of the analysis.

철도에서는 열차가 출발할 때 착력을 향상시키기 위해 레일과 차륜사이에 모래를 살사하게 되는데 이때 ATC(Automatic Train Control : 열차자동제어장치) 신호파형에 영향을 줄 수 있다는 판단에 따라 시험운행하면서 ATC 차상장치인 TVM 430의 CRNB 보드 내에서 살사동작 후 신호파형을 측정하고 분석하였다. 이로 인해 다중화 되어 있는 차상장치 시스템의 동작상태와 살사재료별 ATC 신호파형에 미치는 영향성을 파악할 수 있었으며 향후 살사로 인해 발생되는 문제점 등의 연구에 활용될 수 있을 것으로 판단된다.

This paper proposes the Train Control System for the LRT(light rail transit). With regard to information processing in car, we build a computer network in the car, turned the hardware required for train control into software, and developed the Train Control Monitoring System(TCMS) and ATC. Drive Type of Train control system car can drive with Driverless mode basically, and this paper applied 10Mbps special communication type for car control, data analysis, The propulsion efforts and breaking effort can control the cars. It is used Vector Control in Propulsion control and proposed Operating pattern for Propulsion control thinking Operating data of Rubber Tire LRT.
