초록

TCS secures safe separation between a preceding train and a following train, and protects train collision accident and derailment accident by setting interval speed limit in accordance with track alignment(radius of curvature, gradient, bridges etc.) and train performance(maximumspeed, braking performance, train length etc.). To protect train accidents which commonly occur in driverless operation, automatic operation, manual operation, TCS confirms risk source in train route control, train safe separation control and train speed limit protection to prevent failure and applies measure to remove or reduce it. In the case of train route control, adequately proven interlocking logic based onmoving block in revenue driving wouldapplyso that riskanalysis innot required. In the case of train safety space control(safe separation) and train speed limit protection, TCS needs to analyze the risk source because it applies CBTC (Communications Based Train Control) moving block. This paper analyzes rick source for train control technology which applied CBTC movingblock, and suggests ways to reduce it.
