Personel Proximity Warning & Alert System in Saudi Arabia
Tag-Based PWAS for Worker-Vehicle Safety
Instant Alerts When People Enter Danger Zones
Shield Sensor’s Tag-Based Proximity Warning & Alert System (PWAS) protects workers by detecting their presence near moving vehicles and heavy equipment using wearable safety tags.
When a tagged worker enters a predefined danger zone, the system triggers instant audible and visual alerts inside the vehicle—helping operators react before an accident occurs.
- Ideal for pedestrian-heavy worksites
- Approved for ARAMCO & NEOM-aligned projects
What Is a Tag-Based Proximity Warning & Alert System?
A Tag-Based PWAS System uses wearable electronic tags assigned to workers, which communicate with vehicle-mounted receivers.
When a worker wearing a tag comes within a predefined risk zone around a vehicle or machine, the system:
- Detects the worker instantly
- Triggers in-cab audio & visual alerts
- Provides early warning to prevent collisions
This system ensures person-specific detection, making it one of the most reliable solutions for pedestrian safety.
Why Pedestrian-Vehicle Accidents Still Happen?
On Saudi worksites, many serious incidents occur because:
- Workers are hidden in blind spots
- Operators cannot see behind or beside large vehicles
- Pedestrians are distracted or unaware of moving equipment
- Noise and dust reduce situational awareness
Tag-Based PWAS solves this by alerting both people and machines automatically.
How Shield Sensor’s Tag-Based PWAS Works ?
1. Worker Tag Assignment
Each worker is issued a wearable safety tag (helmet, vest, or belt-mounted).
2. Proximity Detection
Vehicle receivers continuously scan for nearby tags.
3. Risk Zone Entry
When a tag enters the configured danger zone, the system detects it instantly.
4. Immediate Alerts
Operators receive visual and audible warnings inside the cabin.
5. Preventive Action
Vehicles slow down, stop, or take evasive action before contact occurs.
