Vehicle collision avoidance, pedestrian protection and proximity detection (PDS)
Accidents happen in underground mines, open pits, warehouses and plants, including collisions of haul trucks and other vehicles and machines striking people.
Factors behind such accidents
- employee inattention;
- violation of safety rules;
- warnings that cannot be heard because of noise.
Monitoring compliance with safety rules is one of the most important tasks for any company: it affects performance and can also lead to regulatory inspections and significant costs in compensation and fines.
The RealTrac system can
One of the functions of the modular RealTrac industrial safety system is preventing vehicle collisions and pedestrian strikes and warning employees on site about dangerous proximity.
- detect dangerous proximity between machines and personnel;
- warn the operator or driver that a person is dangerously close to the vehicle;
- warn an employee that they are dangerously close to a vehicle.
Employees on site receive personal tags that let the system detect their location. Vehicle tags and antennas installed on the machines create three dangerous-proximity detection zones around each vehicle.
Three dangerous-proximity detection zones
Attention zone
Detects possible dangerous proximity and draws employees' attention to approaching another object.
Light signal
- indicator on the driver's dashboard
- LED on the personal tag
Sound signal
- repeating beep inside the cab
Vibration
- single vibration of the tag
Danger zone
Detects critically dangerous proximity below the minimum permitted distance between vehicles and employees.
Light signal
- indicator on the driver's dashboard
- LED on the personal tag
- beacon on the outside of the cab
- flashing yellow marker lights on the vehicle
Sound signal
- frequent repeating beep inside the cab
Vibration
- repeated vibration of the tag
Emergency zone
Generates an alarm in an emergency or at extremely dangerous proximity and can stop machines and vehicles.
Light signal
- emergency beacons on the vehicle
- LED on the personal tag
Sound signal
- siren on the vehicle
- horn on the vehicle
Vibration
- continuous vibration of the personal tag
Autonomous operation
The system works autonomously and needs no connection to the positioning system or the internet. You can always be sure it will detect an employee dangerously close to a machine and send a warning regardless of other factors.
The system also detects dangerous proximity between two vehicles or any other machines, which helps prevent collisions and avoid significant repair costs.
RealTrac Collision Avoidance System (CAS) is designed to support the EMESRT Performance Requirement 5A (PR-5A) for vehicle interaction systems: vehicle to person, vehicle to vehicle and vehicle to equipment or environment.
