Description
Summary:Driver Machine Interface (DMI) is a slave unit of the train onboard computer in the ERTMS automatic train control system. The SAFEDMI project aimed at the development of a DMI which fulfills the requirements of Safety Integrity Level 2 according to the CENELEC development standards. The main challenges were (i) the reduction of the hardware complexity and costs by implementing the safety mechanisms in software and (ii) provide a safe and secure wireless communication interface to support diagnostics and maintenance. This paper presents the requirements, the design of the architecture and the wireless communication protocol, and the evaluation of the applied solutions. [PUBLICATION ABSTRACT]
