How to Improve Public ServicesHong Kong has numerous large‑scale infrastructure projects, including bridges, tunnels, reclamation works, and high‑rise building sites. Workers are spread across vast areas with complex operating environments, making it difficult for traditional management methods to track their locations and safety status in real time.

In the event of an accident (such as a fall from height, heatstroke, or heart attack), site supervisors often cannot quickly pinpoint the incident location, delaying the golden rescue window. Moreover, workers operating in confined spaces or high‑noise environments find it hard to call for help by shouting or using mobile phones, posing significant safety risks.

This solution is a smart device that can be attached to any standard safety helmet. It features built‑in high‑precision GPS positioning, a high‑definition camera, two‑way voice broadcast, and an SOS one‑touch emergency button. The device transmits workers' real‑time locations, movement trajectories, and first‑person view footage to the site management platform via 4G/5G networks. When a worker presses the SOS button or the device detects abnormal stillness (fall detection), the system immediately marks the distress location on a map, simultaneously notifies nearby co‑workers and safety supervisors, and activates the camera to view the scene in real time for effective rescue coordination.

Managers can also send voice broadcasts to specific zones or all workers via the platform (e.g., typhoon warnings, evacuation instructions, or safety reminders), ensuring that information is accurately delivered to every individual.

Benefits

Enhanced emergency response speed: In the event of an incident, managers can pinpoint the worker's location and view live footage within seconds, reducing rescue time by approximately 70% and significantly improving survival rates and injury control;

Strengthened personnel management efficiency: The backend displays real‑time distribution and daily tracks of all workers, facilitating working hour calculations, attendance checks, and access control to hazardous areas, while reducing management disputes;

Reduced workplace injuries and legal risks: Real‑time voice broadcasts alert workers to potential dangers (e.g., lifting zones, high‑temperature areas), lowering accident rates; and

Video records also serve as objective evidence for incident investigations, clarifying liability
