BASIC TRAIN PROTECTION & FLEET MONITORING:
RPS provides the position of the train with 1m accuracy without any infrastructure adaptation in a reliable and low cost manner. Our ultra precise speedmeters in combination with the radar signature of the ground profile pre-stored in memory allow to determine the position of the train precisely. The scanned profile of the last meters performed by the train is correlated with the radar ground profile of the complete path that has been previously stored in memory. Theposition information is compared against GNSS data and inertial systems in order to achieve SIL4 requeriments. BTP uses position and speed data for warning the driver in case of overspeed according to the specific speed limitation along the complete path stored in memory. In worst case, BTP can perform an emergency break by activating a SIL4 relay.
CBTC POSITIONING SYSTEMS AND TARGET BRAKING:
RPS technology uses encoded information similar to RPS Series A (enlace a RPS Series A) along the network for Communications-Based Train Control (CBTC) systems. As a result real-time and 1cm accuracy is achieved in a reliable, safety and secure manner. This extreme accuracy allow to reduce headways by defining precise train footprints in moving block systems and for providing an adaptive breaking curve at stations where Platform Screen Doors are deployed.
