Safe Driver Machine Interfaces for ERTMS automatic train control -- SafeDMI

The increasing level of train traffic and the spread of high-speed rail lines are now demanding an increasing safety level in the automatic train control(ATC) systems. The architecture for the on-board ATC encompasses a Driver Machine Interface (DMI) component. The objective of the SAFEDMI project is to design and develop a DMI system that satisfies high safety requirements and has an integrated wireless interface for configuration and diagnostic purposes. Technical solutions for HW and SW that addresses the safety and fault tolerance issues according to the SIL2 (Safety Integrity Level 2) requirements will be developed. To develop a safe wireless communication solution for remote maintenance and diagnostics, design of safe protocols is requires. The envisioned scenarios include one-hop short range communication and multi-hop connection to a remote centre via a bridge device. Additionally, a feasibility study on the possibility of using the wireless connection for on-board communication will be performed.
