This paper proposes the hardware implementation of a novel in-cabin module to realize a smart surveillance on autonomous train operations (ATO). The proposed smart surveillance module (SSM) consists of a 10-layers PCB carrier card holding a central computing core based on an Ultrazed-EG system on module (SoM). To interface cabin equipment, the SSM includes several common communication buses in the railway context, favoring its inclusion in already existing apparatus. The SSM also provides a multi-piggyback slot, whose layout is designed to allow the independent housing of two different communication boards (Profibus or Continuous Signal Repetition), when included in a redundant architecture. These functionalities have been condensed in a single Eurocard board with a height of only 4 horizontal pitches. To improve the fault detection, the SSM has been also supplied with several diagnostic interfaces concerning power management, debugging and diagnostic and SoM temperature monitoring.

Abstract

This paper proposes the hardware implementation of a novel in-cabin module to realize a smart surveillance on autonomous train operations (ATO). The proposed smart surveillance module (SSM) consists of a 10-layers PCB carrier card holding a central computing core based on an Ultrazed-EG system on module (SoM). To interface cabin equipment, the SSM includes several common communication buses in the railway context, favoring its inclusion in already existing apparatus. The SSM also provides a multi-piggyback slot, whose layout is designed to allow the independent housing of two different communication boards (Profibus or Continuous Signal Repetition), when included in a redundant architecture. These functionalities have been condensed in a single Eurocard board with a height of only 4 horizontal pitches. To improve the fault detection, the SSM has been also supplied with several diagnostic interfaces concerning power management, debugging and diagnostic and SoM temperature monitoring.
