APPARATUS FOR WARNING OF EXCEEDING SPEED LIMIT IN RAILWAY VEHICLES

摘要

The present disclosure relates to an apparatus for warning of exceeding speed limit in railway vehicles, wherein a train speed is estimated after a predetermined time, a remaining time is calculated until a train reaches a speed limit based on the estimated speed, and when the calculated time is smaller than a preset reference value, a warning signal is generated. Thus, an adequate warning can be given to cater to a train operation situation because a TTSLC indicator is used that notifies when an emergency braking will be activated by exceeding a set speed limit value after a certain time lapses, resultantly increasing the train operation frequency and the availability of trains.

主权项

1. An apparatus for warning of exceeding speed limit in railway vehicles, the apparatus comprising:
a future speed estimation unit configured to estimate a future speed subsequent to a predetermined time of a train; a TTSLC {Time-To-Speed-Limit Crossing, a time when the train exceeds an ATP (Automatic Train Protection) speed limit} calculation unit configured to calculate a time when the train speed reaches a preset limit speed, using the future speed estimated by the future estimation unit; and a warning generation unit configured to generate a warning signal when the time calculated by the TTSLC calculation unit is smaller than a preset reference value.
