Rail certified, high performance computing platform enhances Wi-Fi based passenger infotainment

Author: Chris Shaw

Impulse were approached by an innovative digital media company with a requirement for a EN50155 rail certified high performance computing platform to provide advanced passenger Wi-Fi and streaming facilities to passengers utilising multiple 4G cellular data connections.
We have been providing hardware for passenger infotainment systems for some time, and whilst the specification requirements were similar to previous projects, our customer was limited by space, so we had to provide an alternative solution in order to be respectful of the limitations for these particular vehicles whilst also being mindful of the certification and electrical standards expected in rolling stock applications. 

The customer was provided with a complete and thorough documentation pack with all test and certification documents, along with user manuals and installations guidelines prior to commencement of the project, and once we became involved with the project, we worked closely with our manufacturing partners to meet the customers required delivery deadlines, as well as providing multiple system BOMs to allow the customer to control exactly which system specification was being installed in differing consists.

For this project, the Axiomtek tBOX324-894-FL was the ideal choice as it allowed for a platform which was higher performance and expandable, whilst still with a small enough footprint to fit into the space available.  The system could be configured with an Intel® Core™ i7-7600U, along with 32GB memory which was crucial for the performance of this media engine.

We were also able to accommodate 2 x 2TB Innodisk Industrial SSDs in these systems using the dual HDD/SSD bays supporting 9.5mm storage drives, which allowed for a vast storage bank of media to be kept local to the device, keeping 4G data bandwidth for real-time access and internet browsing.
