The Safe4RAIL project started with a State-of-the-Art analysis for avionic, automotive and railway domains, whereby the respective requirements for all associated levels were collected and defined. Based on the analysis, the concept for design and methodology for NG-TCMS up to SIL4 was established. This includes the Drive-by-Data networking platform and the Functional Distribution Framework middleware concept.
For Drive-by-Data, the communication concept was further refined, and proof-of-concept implementations were developed for: (a) Railway Ethernet Switch Core, (b) Integration of Ethernet Network with software Framework, (c) Network Simulation and Modelling environment (d) Network Verification environment, and (e) Network Configuration tool. For the Functional Distribution Framework, the reference architecture solution was finalized, three instantiations and proof-of-concepts based on a) INTEGRITY, b) PikeOS and c) AUTOSAR were developed.
Furthermore, concepts for the distributed simulation framework concept for efficient co-simulation at different sites, and a simulation environment for the validation of TCMS interfaces to ground systems including testing of compliance to relevant railway standards was defined. For this “Virtual placement in the market”, proof-of-concept implementations were developed for a) the distributed simulation framework and b) the Train2Ground Test Environment (T2G TE) and are evaluated using example test cases, real hardware and real MCG implementations.
Finally, the application domain “Brake-by-Wire” focused on the safety aspects related to the development of a Brake-by-wire system, specifically when integrated in a NG-TCMS platform. Within this domain, we completed the systematic safety analysis with two FTA examples to allocate the THR targets, the completion of development for the train emergency brake up to the definition of the requirements applied to Electronic Control devices for hardware and software, and the requirements applied to the IMP. Furthermore, the Hazard Analysis was completed, and safety assessment activities were performed.
In addition to the technological results, Safe4RAIL has provided contributions on the general technical standards such as IEEE802.3 rail specific standard e.g. IEC61375, or safety and security standards e.g. CENELEC.
Moreover, Safe4RAIL has provided significant results with respect to collaboration and dissemination activities. Several dissemination activities have been organized, e.g. ( Safe4RAIL’s Mid-Term Conference in Prague, 25.1.2018 Safe4RAIL integrated demo at InnoTrans in Berlin, 18-21.9.2018).
19 technical paper has been published during the project period for more details please see the project website. Additionally, the project website has been set up, flyers and a poster have been created, project newsletters were released, a podcast recorded as well as a final video summarizing the results made publicly accessible.
