Collision Avoidance Solutions for Tunnel Construction

A complete proximity alert system for above and below ground detections

Enhanced safety, reduced risk

PAS utilises multiple detection technologies for increased detection, and reliability in confined underground environments. An innovative collision avoidance system capable of dectecting light vehicles, heavy vehicles, obstacles and personnel.

A complete proximity alert system for above and below ground detections. Enhanced workplace safety by reducing the risk of collision through asset and personnel detection and warning.

Collision Avoidance

Features/Benefits:

Dynamic Projected Detection Angle (DPDA)

Allows a vehicle’s L9 Canbus and relay actions to be restricted

Dynamic Zoning

Allows a vehicle’s detection and alerting zones to dynamically tighten or broaden proportionally with the speed of the vehicle

Overspeed Alerts

Configurable speed limits for an entire site and/or per geofence display provides audible and visual alerts. Speed limits can be set based on angle of inclination

Emergency Remote Stop

With a configurable activation range PT-Tag can issue L9 stop commands to a vehicle in emergencies, the command can be deactivated by the tag or when the tag is removed from high-risk zone

Maintenance Bypass Mode

Suppresses all CANbus commands, relay outputs and alerts time setting is configurable. Unit resets to normal-mode automatically after time elapses

Linking

Temporarily suppress alarms and actions generated from an interaction with a specific vehicle. Used when two vehicles are close to one another to perform a controlled task, such as when loader and haulage truck are gathering bulk materials

Attachment

Temporarily suppress alarms and actions generated from an interaction with a specific tag. This is useful for instances in which one or multiple tags must be very close or inside of a vehicle, such as when any driver enters a vehicle with their personnel tag

Low tag battery

Display indicates all tags within its zones with a low battery

Authorised Drivers

Ensure only trained, authorised drivers are able to operate a given vehicle containing a PAS system

System Caution/Faults

Caution is a system alarm indicating high system traffic that could impact the accuracy/performance of the PAS system.
Deem the system to be inoperable under the commissioned performance specifications

LTE Solutions for Tunnels

Smart connectivity solutions to improve safety, sustainability, productivity & efficiency

Reliable, efficient, secure & flexible

A PBE Axell private LTE network creates a connectivity area within the tunnel, where all devices and machinery can be monitored and controlled. An LTE network increases flexibility without reliance on local providers to make changes, creating additional secure networks or moving devices from one network to another. Over traditional Wi-Fi systems LTE solutions provide improved handovers and roaming for all services below ground. A private LTE network allows control of network access, critical for securing data and device access. Private LTE allows for setting up specific levels of security access for different on-site members.
