Accidents involving vehicles backing up are a frequent safety concern on worksites. The Proximity Warning and Alert System (PWAS) is engineered to reduce these types of incidents. Unlike systems that depend on individuals wearing identifiable tags, this PWAS employs sensors to identify all nearby people and objects, even if they aren't tagged. By issuing warnings and working with the vehicle’s control systems, this technology helps avoid collisions and boosts safety on the worksite.
The PWAS control unit is installed next to the heavy equipment operator inside the vehicle. It triggers an alarm whenever it detects personnel or objects approaching the hazard zone, alerting the operator to potential dangers. The unit also records events and hazards, providing valuable data for evaluating and managing worksite risks.
The PWAS sensor is installed on the rear of the vehicle, creating an extensive detection zone that identifies personnel and objects. The standard detection range is set to eight meters, with the flexibility to be adjusted based on the specific requirements of the site.
Integrating the PWAS Camera and Monitor with the PWAS enhances operator confidence by improving visibility of personnel and property in the machinery's blind spots. Cameras are installed at both the front and rear of the machinery, while the monitor is situated in the cab to provide clear visual feedback and alerts. Additional cameras can be added as needed to meet specific site requirements.
