RTI and Industry Players Collaborate on Safe Computing Platform

RTI Railway
Many railways aim to introduce large degrees of automation in rail operation.

The railway sector in Europe is on the verge of its largest technology leap in history, with many railways aiming to introduce large degrees of automation in rail operation in order to substantially increase the capacity, quality and efficiency of the rail system.

​​Besides the introduction of enhanced Control Command and Signaling (CCS) approaches, and the introduction of novel technologies such as advanced sensing and artificial intelligence into the rail system, it is also necessary to design the appropriate IT platforms for future rail operation. 

In this context, the railway initiatives Reference CCS Architecture (RCA) and Open CCS Onboard Reference Architecture (OCORA) started working on a Safe Computing Platform concept in 2020, which is expected to provide the basis for safety-relevant railway applications for both onboard and trackside developments.

A key design paradigm is the introduction of a standardized method for separating applications from the computing platform. This decouples domains with very distinct life cycles and leverages advances in the IT sector, while still leaving room for vendor differentiation on the detailed computing platform implementation. 

Who is involved? 

To take this work to the next stage, the railways and industry players

  • DB Netz AG
  • duagon AG
  • Nederlandse Spoorwegen
  • Real-Time Innovations (RTI)
  • SBB, Siemens Mobility GmbH
  • SNCF Voyageurs
  • SNCF Reseau
  • SYSGO GmbH
  • Thales
  • Wind River

have now teamed up to jointly develop a first version of the possible Application Programming Interface (API) between railway applications and the Safe Computing Platform. The work is expected to be published in Spring 2022 through RCA and OCORA to serve as a basis for prototyping Safe Computing Platform implementations.

What is RTI's Role? 

Among its contributions, RTI will focus on a safe and reliable communication architecture and API definition between railway applications and the Safe Computing Platform (SCP). 

Real-Time Innovations (RTI) brings extensive experience in communications for the rail systems market. RTI Connext®, built on the Data Distribution ServiceTM (DDS) standard, enables intelligent information exchange from onboard and remote applications, resulting in an efficient, scalable, and future-proof data processing infrastructure. Its standards-based data distribution infrastructure can connect thousands of onboard mobile and remote assets, transmitting data from dispersed sources, and aggregating it for real-time analysis and response.

Reducing the pre-development phase with the Rutronik Adapter Board -RAB2

Rutronik System Solutions expands the existing product portfolio with the new Adapter Board – RAB2 for CO2 Sensing. The board offers a unique approach using CO2 sensors, comparing two ultra-modern sensors from Infineon and Sensirion. That provides the opportunity to use one board in the pre-development phase to evaluate which sensor suits a specific application most. As a result, the time-to-market for applications requiring CO2, relative humidity, and temperature measurement is significantly shortened.
