Overview
Enabling low-cost railway digital transformation through interoperability and digital blocks.
Railway industry is at a digital-transformation crossroads.
SMEs lack modern development environments.
Full digitalization drives excessive D-T cost.
Trosar supplies digital-transformation technology for railways.
Digital-Block stacking reduces D-T cost and upgrades easily.
Core Competencies
Purpose
Integrated platform for mutual compatibility of railway control devices.
Mutual compatibility between control devices from different manufacturers.
Components: Trosar Portal, Trosar CyberSpace, Trosar Engineering Tools, Digital-Blocks.
Digital-Block based PLM and Digital-Twin virtual environment system.
CyberSpace/CyberManual: create virtual-space and digital-twin contents.
Procedure: Digital Block data conversion → scenario definition → Trosar XR Studio.
XR Studio: linking drawings, documents, and videos.
XR Viewer: 3D augmentation with rotation and zoom in/out.
Augmented simulation for hands-on training.
Digitalization → Digital Blockization → Digital Engineering application.
Digital-Block: digitized systems with gray zones removed.
