  Abstract

Train control systems maintain intervals between train to prevent collision and stop the train precisely at the platform for passengers to get on and off conveniently. Threfore train control system should know the train location accurately. Train control system calculates the train speed by multiplying wheel diameter with the rotation rate acquired by tachometer and this speed information is shared with each devices in the train control system. The delay occurs when the rotation information measured by tachometer is transferred to the train control system, and the delay increases if this information is transferred in series for one device to another device. The train location calculated with delayed speed information contains noticeable error hence this becomes one of major cause of deteriorating the control accuracy. In this paper, experimental method to estimate the speed transmission delay is proposed. If train is decelerating with a difference between given distance and calculated distance. Proposed method can estimate the transmission delay even in the presence of a measurement error for wheel diameter. Applicability is represented by showing the localization accuracy is increased if the train speed is compensated with the delay estimated by the proposed method experimentally.
