CONtributing to Shift2Rail's NExt generation of high Capable and safe TCMS. PhAse 2.

Periodic Reporting for period 1 - CONNECTA-2 (CONtributing to Shift2Rail's NExt generation of high Capable and safe TCMS. PhAse 2.)

Reporting period: 2018-10-01 to 2019-12-31

According to the DoA of the project, the high level objective of the work is to continue the activities started in CONNECTA-1 to bring the technologies to TRL4/5 and deploying them in relevant laboratory scenarios. During this Reporting Period the specifications made in CONNECTA-1 (D3.5 D4.3 D4.4 and D6.4) have been taken and the following prototypes have been deployed:
• FDF prototypes; one based on Autosar AP and another based on Integrity RTOS.
• TRDP adaptation for TSN and its integration in both FDFs.
• OPC-UA integration in Autosar AP-based FDF.
• New inauguration with topology validation without train lines.
• New SDTv4 safety layer.
• Deployment of service-oriented FOC in the CCU.
• Deployments of Simulation Frameworks.
• Deployment of T2G Wake-up Service and File download.
• Deployment of the Adapted ETBN and the wireless inauguration needed for the evolved WLTB.
These deployments allow achieving TRL4/5 but still have to be integrated and validated in laboratory environments.
Apart from the mentioned deployments, CONNECTA-2 has been active in the definition of new specifications in WP1. This is not only the case of the evolved wireless TCMS, which includes WLTB, WLCN and T2G-ACS integration, but also the definition of new application profiles, such as Lavatories and ATO-TCMS interface up to GoA2. Additionally, extensions to the existing definitions of HVAC and Doors Application Profiles have been provided in order to make them more detailed. Extensions for FDF requirements have been also provided based on the implementation experience, which complement the specification made by CONNECTA-1.
Last but not least, the definition of functions for a standardized DMI has been done, as well as the completion of FOC regarding its visualization.

The work carried out along this Reporting Period has provided the needed experience to amend or complement the specifications of the NG-TCMS. With this experience technical input for standardization can be done following the Standardization plan shared with the Shift2Rail JU which includes contributions to:
• CENELEC TR 50542
• IEC 61375 series
• TRAINET
The standardization activities will start in 2020. Due to the large number of contributions, mainly in the IEC WG43 handling the IEC 61375 series, a submission plan will be prepared in the next WG43 meeting in May. The validation tests to be made in 2020 and 2021 are expected to serve as inputs for standardization bodies, providing clear and common methodologies for the validation of new technologies.
During the RP1, WP1 and WP3 were successfully closed, which include the following tasks:
• Task 1.1: Specification of the evolved Wireless TCMS
• Task 1.2: Definition of new application profiles
• Task 1.3: Definition of new FDF requirements
• Task 1.4: Definition of functions for DMI for standardisation
• Task 1.5: Review and completion of FOC regarding visualization
• Task 3.1: Technical specification for urban demonstrator
• Task 3.2: Design and implementation of components for urban
• Task 3.3: Technical specification for regional demonstrator
• Task 3.4: Design and implementation of components for regional demonstrator

Within the T1.1 the evolution of Wireless TCMS, including T2G, WLTB and WLCN has been specified. T1.2 has defined new Lavatories Application Profile and it has completed the ATO and HVAC Application Profiles. T1.3 has extended the FDF requirements defined in Connecta-1 with the experience obtained in the implementation phase within the WP3 of this project. T1.4 has made the definition of functions for DMI for standardisation. Following this work, the T1.5 has completed of Function Open Coupling regarding the input and output needed for DMI visualization.

In WP3, the T1.3 and T3.3 have defined architectures for regional and urban technical laboratory demonstrators respectively. This define not only the architecture but also the specification of demonstrator componentes (network devices, CCU, IO, ...). It also has specified the FDF and Doors/HVAC applications, as well as the needed simulators (ETB simulator, subsystem emulators and TCMS virtualization). T3.2 and T3.4 have been responsible for designen and implementing the prototypes of technologies to be equipped in demonstrators. These two tasks have also carried out safety analysis of the two safety functions safe train inauguration and safe data transmission.
CONNECTA-2 project within this period has deployed prototypes for NG-TCMS. These technologies, such as FDF, DbD and Application Profile based functions suppose a clear step forward beyond the state of the art. For the first time, the building blocks for testing the a TCMS able to allow SIL4 applciations, while removing train lines, have been deployed.
