Railway Onboard Computer
The onboard computer is the system's high-level compute core and runs local video multimodal models on a heterogeneous parallel platform. It connects to the onboard video gateway for aggregated, encoded, and pre-filtered standardized video streams and connects to the onboard data gateway for LKJ operating data plus the unified timebase. It fuses these two gateway outputs locally to identify line and undercarriage risks and generate alarm reports with key frames.
Core capabilities
Complete Local Multimodal Inference
Combines standardized video streams from the video gateway with operating conditions from the data gateway and completes inference locally without cloud support.
Long-Range Line and Moving Undercarriage Analysis
Optimized operators distinguish 500-meter landslide and rockfall imagery and fine running-gear defects captured at 20 km/h.
Resident Quantized Models
Supports lightweight model quantization, persistent local operation, automatic snapshot extraction, and partitioned archiving.
Tiered Alarm Delivery
Prioritizes high-risk line events and major undercarriage faults on the driver-cab tablet.
Offline Analysis and Cache
Continues analysis without connectivity and caches complete snapshots and conclusions for later synchronization.
Remote Differential Model Updates
Differentially updates recognition weights to improve line-hazard and undercarriage-defect performance.
