TRAIN SPEED LIMIT CONTORL METHOD

摘要

A train speed limit controlling method is provided to maintain the driving speed of a high speed train at limit speed by transmitting a limit speed alarm display command signal to an ATC(Automatic Train Control) apparatus according to a control signal of a TSL(Train Speed Limit) control module. A train speed limit controlling method includes the steps of: inputting a predetermined speed limit alarm display signal to an SCU(Supervisory Control Unit) when a TSL control blocking signal and a TSL control error signal are not inputted; outputting a predetermined speed limit alarm display command signal to an ATC by the SCU using a network signal when the speed limit alarm display signal is inputted; and maintaining the driving speed of a high speed train at predetermined speed by the ATC to receive the predetermined speed limit alarm display command signal.
