VIRTUAL CERTIFICATION Simulation Framework and Train

received funding from the European Union s Horizon

Joint Undertaking under grant agreement No: 730830.

1 VIRTUAL CERTIFICATION Simulation Framework and Train Virtualisation Mikel Colera (CAF) CONNECTA has received funding from the European Union s Horizon 2020 research and innovation programme under agreement No: Safe4RAIL has received funding from the Shift2Rail Joint Undertaking under grant agreement No: This Joint Undertaking receives support from the European Union s Horizon 2020 research and innovation programme. 139

2 What is VIRTUAL CERTIFICATION? It is the VALIDATION/CERTIFICATION of a TCMS SYSTEM and its subsystems in a lab environment with local/distributed virtual/real devices. TCMS SYSTEM TCMS SUBSYSTEM 1 CU TCMS SUBSYSTEM 2 CU SCHEMATICS & SENSORS TCMS SUBSYSTEM 3 CU TRAIN DYNAMICS 140

3 What is VIRTUAL CERTIFICATION? Test Bench 1, location 1 Test Bench 2, location 2 TCMS SYSTEM Heterogeneous Network TCMS SUBSYSTEM 1 CU TCMS SUBSYSTEM 2 CU TCMS SUBSYSTEM 3 CU SCHEMATICS & SENSORING TRAIN DYNAMICS 141

4 Why VIRTUAL CERTIFICATION? Current state Origin lab testing Development Train manufacturing and deployment Factory Testing On-track Testing 142

5 Why VIRTUAL CERTIFICATION? Future state Origin lab testing, powered with SF, TV and CE Development Train manufacturing and deployment Time saving Factory Testing On-track Testing 143

6 Why VIRTUAL CERTIFICATION? Today With VIRTUAL CERTIFICATION TCMS system integration test with its subsystem are done with the real system and subsystems. TCMS system integration with its subsystems will be done in a lab environment with some real devices and some simulated devices. The devices will be located locally or remotely. TCMS system and subsystem integration with the train is done with the real train in track. TCMS system and subsystem integration with the train will be done in a lab environment with simulated train environment information: schematics, wiring, train dynamics, etc. Certification of the train is done with the real train in track Partial or complete certification of a train will be done in a lab with simulated and distributed devices, simulated environment information. 144

18 COMMUNICATION EMULATOR Concept Design of a simulation bridge between real and simulated devices Local or geographically distributed devices Connection via heterogeneous communication networks (Internet, Local Area Networks, etc.) Definition of a generic interface based on Ethernet 156

19 COMMUNICATION EMULATOR Concept Synchronization and data exchange between devices Configuration for different protocols and real/simulated devices Mechanisms for monitoring and fault-injection (EN 50159) Management of delays introduced by the heterogeneous network Measure delays and stop simulation if threshold exceeded Estimate future input packets and forward packet to device if delay too large 157

24 Conclusions In order to validate the development to use it for the validation /certification of a train, first we need to test and compare the results with those of a real environment. Validation of time sensitive requirements by means of distributed devices may be not achievable with the current technology. Standardisation of this technology is highly recommended by the experts in order for all the stake holder to accept the virtual certification. Integration activities must be carried out in CTA 2 in order to have a whole working system. 162
