The Online Driver Fatigue Monitoring System (DFMS) enhances safety for HEMM, fleet, and heavy-duty vehicles in mining, construction, transportation, and logistics, where long hours and harsh conditions increase the risk of fatigue-related accidents. Using AI-powered facial recognition and infrared eye-tracking, it monitors eye closure, yawning, head position, and attention levels in real time. The system connects to its online platform, allowing fleet managers to track driver activity remotely and receive instant email notifications if fatigue or distraction is detected, enabling proactive intervention and improved operational safety.
