Objectives

CONNECTA aims at contributing to the Shift2Rail ’s next generation of TCMS architectures and components with wireless capabilities as well as to the next generation of electronic braking systems.

The project conducts research into new technological concepts, standard specifications and architectures for train control and monitoring, with specific applications in train-to-ground communications and high safety electronic control of brakes.

The project is developed in four phases of work which are reinforcing and extending the early work done in the TCMS part of Roll2Rail as well as start the specific activities of the MAAP of Shift2Rail. The major streams are described below.

  1. Define General Specifications for TCMS technologies and high-level architectures to shape the future system with less cabling, increased availability, enhanced performance, easier integration and commissioning of functions and, above it, reduced life cycle costs.
  2. Progress and implement new architectures and technologies, tools, norms and standards for the future generation of TCMS as well as for high safety level electronic brakes.
  3. Simulate and test virtually all the communication networks and functions of the new generation TCMS subsystems to help to simplify business processes and enhance the interoperability.
  4. Evaluate results, disseminate, communicate and exploit as much as possible at this TRL3-4 level of achievements.

Project Structure

WP1 General specifications

The main objective of this WP will be to work out a general specification of the next generation TCMS (Train Control Management System) and to generate a high level system architecture that is able to provide specific requirements as input to the different tasks of the other WPs.
The main objectives of WP1 are to:
  • Provide a basis for collaboration and collecting required data
  • Collect all TCMS relevant Use Cases
  • Provide a functional (function based) architecture (meaning that TCMS functions are pictured as back boxes including their logical links)
  • Collect and provide all functional (top level) requirements
  • Collect and provide legal requirements, norms, standards, SIL Levels, …
  • Include functions for future needs of the specification
  • Reduce the overall cost of the TCMS system
  • Increase reliability of the IT system (TCMS) and decrease LCCs
  • Requirements as basic inputs for a flexible and scalable TCMS, which features single sources for common data and supports an open data exchange to coupled vehicles.

WP2 Wireless TCMS and Train to ground

The research began within Roll2Rail, where members collaborate in the basic definition and selection of the wireless technologies (incl. physical medium, architecture, protocols, RAMS & (cyber)security analysis and testing in lab …) for the train to train, intra-consist, consist to consist and train to ground (T2G) communications and for several applications (TCMS, safety functions, CCTV – Closed Circuit Television -, infotainment).
These inputs from Roll2Rail and WP1 will be reviewed and considered. Members are expected to then develop technical solutions (HW & SW) oriented to the metro segment as well as for main line vehicles, which may include wireless routers, transmitters and receivers, adaptation of software communication layers for T2G related applications. Unitary test on real vehicles before integration in the metro and regional ITD is foreseen in a later call (TRL6/7).
The members will collaborate in the basic definition and selection of the wireless technologies (incl. physical medium, architecture, protocols, RAMS & (cyber) security analysis and testing in lab…) for the train to ground (T2G) communications and for several applications (TCMS, safety related functions, CCTV, infotainment...).
The partners will then develop technical solutions consisting of hardware and software, which may include wireless routers, transmitters and receivers, and adaptation of software communication layers for the complete T2G functionality.
Another goal of this WP is to continue the validation of the technologies and architectures for the wireless TCMS starting from the outcomes of Roll2Rail and taking the laboratory testing infrastructure to a real environment at first for the consist to consist application.

WP3 Drive by data

The objectives of this WP can be summarised as follows:
  • Provide a ‘business case’ for drive-by-data
  • One train-wide communication network for full TCMS support including the replacement of train lines, which supports the secure separation of data traffic belonging to different safety integrity classes in a manner acceptable by regulatory authorities.
  • Connecting safety functions up to SIL4 and support of ‘fail-safe’ and ‘fault-tolerant’ principle.
  • Provide an optimal train network for TCMS and OMTS (on-board multimedia and telematics) services, by considering quality of service aspects like determinism, real-time behaviour, demand-response-time, guaranteed bandwidth or jitter.
  • Provide requirements on end devices (e.g. to approve network conformity and to ensure requested end-to-end demand response time) also as input for WP4 and WP5
  • Provide a communication mean also for non-TCMS functions like signalling subsystems
  • Support standard methodology & process of safety approval / authorization

WP4 Functional distribution architecture

The objective of functional distribution architecture is to standardise functional interfaces of functions and sub systems as well as define a generic functional distributed architecture for the next TCMS generation.
The objective of function standardisation and open coupling is to make possible the coupling of two or more consists supplied by any manufacturer and which could have different train functions. It would also allow the control-command and monitoring of a train made of different consists supplied by any manufacturers. In order to achieve this, it is intended to elaborate application profiles for each sub-system of the train and specify, design and develop a prototype of open coupling.
The application profile will define the standardised interfaces for each sub system of the train.

WP5 High Safety Level Electronic Solutions for Brake Control

This work package aims to develop an electronic HW-SW architecture designed to manage all the braking functions (service, holding, emergency, safety brake, wheel slide protection) according to proper high safety levels (SIL3, SIL4).
Main objectives are:
  • Performance improvement in safety relevant braking functions resulting in optimisation of the braking distances in safety braking
  • On board system optimisation, reducing the number of sophisticated pneumatic components, improving overall LCC
  • Use of communication standards carrying high SIL related information coordinated with WP3
  • Validation of non-railway EN standards to be used in railways safety related application.

WP6 Virtual Placing on the Market

The main goal is to develop a simulation framework in which all subsystems of the train can be simulated, allowing remote and distributed testing including hardware in-the-loop through heterogeneous communication networks.
Specific goals have been defined in WP6:
  • Specification and Definition of a standardised simulation framework
  • Support virtual testing and homologation of the TCMS and its applications
  • Allow local and remote homologation through heterogeneous networks and HW-in-the-loop.
  • Complete train virtualisation based on electromechanical simulations
  • Test design, deployment and monitoring toolbox development.
  • ECN/ETB conformance testing definition and implementation
