SYSTEM AND METHOD FOR FOLLOWING SPEED-LIMIT CURVE OF ATP SYSTEM USING GROUND EQUIPMENT OF ATS SYSTEM

摘要

PURPOSE: A system and a method for ATP speed limit curve following are provided to follow the ATP speed limit curve and an approximated curve by using the ATS ground equipment. CONSTITUTION: A ground apparatus(130) includes a trajectory occupying detecting unit(131) deciding the section busy condition of the train from the section track circuit of the line and an ATS ground equipment(133) installed in each section and connected to the trajectory occupying detecting unit. A train apparatus(110) includes a train equipment(113) receiving a limit speed signal of a current occupied section from the ATS ground equipment, a counter(116) counting the counted times receiving a message the limit speed signal, a database(114) storing information on unit disparate distance among the ATS ground equipments and a speed detecting unit(115) detecting a running speed of the train.
