Railway automatic train control (ATC) systems are based both on trackside and on-board systems and their evolution has followed, step by step, the introduction of new technologies. The increasing level of train traffic and the spread of high-speed rail lines are now demanding an increasing safety level in the ATC systems. Up to now, each country has defined its own requirements specification for controlling the train movement and to ensure system safety.
To ensure compatibility and interoperability between the ATC systems produced in the various European countries, the European Rail Traffic Management System (ERTMS) programme has been set up to provide unique functional and non-functional standard requirements. The ERTMS architecture for the on-board ATC encompasses a Driver Machine Interface (DMI) component. Its main functions are the acquisition of driver's commands and the display of that information that support the train driving.
The objective of the SAFEDMI project is to design and develop a DMI system that distinguish itself from other trainborne DMIs currently available on the market by:
- being able to satisfy at least SIL 2 according to CENELEC specifications with all the related implications;
- being able to integrate in such safe DMI safe wireless communication interfaces for configuration, SW and firmware downloading and diagnostic purposes.
The detailed proposed objectives are:
- to design and develop a safe DMI integrated with the current on-board ERTMS systems developed according to the ERTMS Interface specifications
- to study and develop all the HW and SW solutions to properly address the safety and fault tolerance issues generated by the SIL 2 requirements;
- to integrated in the safe DMI safe wireless communication interfaces for configuration, SW and firmware downloading and diagnostic purposes;
- to design and develop a HW and SW tool infrastructure to support automatic test execution, simulating driver's action.
