Chapter 10. openETCS Model Reverse Movement Protection Activates the emergency brake system in the case that the train moves in the reverse direction. See Figure 10.15. Since different telegram types can be received in Staff Responsible, all of them must be treated in the corresponding sub-function “Telegram Evaluation in Staff Responsible”. The evaluation of MAs is modelled analogously to the Unfitted Mode in Subsection 10.2.3 and is only needed for a possible transition to Full Supervision. Current Train Position double double Start Position SR bool Store position of train during mode activation. SR Entered AllowedDistanceInSR double double + double Absolut Distance Permitted in SR Start Position SR Calculate absolute distance (for odometer values) until SR mode is allowed by using national value. AllowedDistanceInSR double >= double 0.0 (CONST) Check if allowed distance in SR is infinite (< 0). bool Check if absolute distance allowed in SR is overrun. Current Train Position double double Absolut Distance Permitted in SR > & bool Allowed Distance in SR overrun bool Figure 10.12.: Distance supervision in Staff Responsible as gSubFunctionBlock graph 10.2.5. Full Supervision Mode In Full Supervision, the EVC completely supervises the train movement. To ensure that the train only enters allowed areas of the track, Moving Authorities (MA) [89, pp. 35-47] are used. It is ensured that the train never overpasses the end of a MA without a new valid one has been received before. In general, this procedure is done to provide an automatic spacing of trains [67, ch. 3]. The model of the main functionality is sketched in Figure 10.16. In comparison to Staff Responsible, Full Supervision mainly adds the functionality for automatic train spacing. This is modelled in the “Dynamic Speed Profile Supervision” in Figure 10.17. 192
