Automatic Train Protection (ATP)
ATP is a SIL4 System providing visual and audio warnings to advise the train driver if that train crosses a red signal or exceeds speed restrictions.
Purposes :
- To monitor train speed, jumping red signal, unauthorized rollback, monitor direction of travel, detect train position
- To monitor and enforce any request for a temporary speed restriction imposed on the track
- To activate Emergency Brake (EB) and enforcement of train stand-still
Interfaces :
Onboard ATP System: Onboard Computer (OBC) (SIL4), Wheel Speed Sensor (WSS), Antenna, Train Interface Unit, Driver Machine Interface (DMI) (SIL2)
Wayside ATP System: Lineside Electronic Unit (LEU) (Signal Encoder), Balise
OBC: Central Processing Unit (CPU), Train Interface Unit (TIU), Rolling Stock Interface Unit, Relay Interface Unit (RIU)
Driver Machine Interface (DMI): Display current status (Speed, Mode, Brake) and events received from OBC to Train Driver action
Interface Unit for OBC/Antenna: Receives & Decoding data from Balise
