Reliably Innovative Transit Solutions
Vital UWB Train Positioning
Piper has developed the world’s first SIL4 Safety Certified Ultra Wideband (UWB) Positioning System. Piper’s ETLS™ (Enhanced Transit Location System) uses UWB Technology to track the location and movement of trains, vehicles, equipment, people and other objects in real-time for various location awareness needs. Piper believes that the use of UWB in train control systems is an important evolutionary leap forward for signaling. Because UWB equipment is installed on the wayside and in the interior control cabinets on the train (as opposed to the track bed and the undercarriage of the rolling stock), the positioning systems required to manage train headways can be deployed faster, at lower cost, and with minimal disruption.
Helix™ MoW Solutions
Helix™ is an advanced, multi-sensor Limits Compliance and Collision Avoidance System (LCCAS) that uses LiDAR, UWB and other positioning technologies. The Maintenance of Way (MoW) safety solution allows for fleets of rail-bound and hi-rail equipment to be accurately detected and tracked on the railroad in real-time, thereby reducing the potential for worker injury, equipment damage, and operational disruptions resulting from accidents or major rule violations. The solution provides: Limits Compliance, Collision Avoidance, Collision Detection, Object & Worker Detection, Live HD Video, and Real-Time Employee-in-Charge & Operator Communication.
SafeGrade Grade Crossing Safety
Piper’s SAFEGRADE system provides remote monitoring of grade crossings to detect occupancy and alert rail system operators to potential hazards. Using Piper’s patented LiDAR technology, the integrated system is designed to capture the presence of vehicles, pedestrians, cyclists, and objects within the crossing quadrant with high resolution.
TrackSight™ LiDAR Positioning
TrackSight™ is Piper’s latest innovation that employs patent-pending positional imaging to determine the location of trains and other vehicles within transit systems. The train-centric solution is the next evolutionary step that moves rail operations from the trackbed to the train itself which makes deployments and maintenance faster, safer and more cost effective. TrackSight™ is a fully deterministic solution that uses Piper’s Solid State LiDAR technology to compare real-time imaging to an onboard database. It can also be installed alongside UWB and provide consistent and redundant positioning data to an onboard CBTC system. And because it requires no track or wayside components, installation and maintenance costs are dramatically reduced.
SecureTrack™ Work Zone Awareness
Piper’s SecureTrack™ solution allows for remote, real-time set up of dynamic work zones. An in-cab alerting system delivers audio/video alerts to train operators indicating proximity to the approaching flagging points. Railway workers are positioned in the system with the use of UWB wearables on their PPE that communicate passively with a portable base station. Track work leaders are issued ruggedized handheld Android devices so that they can communicate directly with the train operator, letting them know when they can release the train and resume movement. The system was designed in accordance with industry standard flagging rules.
Track Worker Safety
Two-way communication between devices on trains and wearables worn by workers trigger safety alarms and lights to warn of the proximity between trains and workers. Flashing strobes in the cab and on worker armbands or vests create simultaneous passive alerts to help avoid injuries. This same technology can be used to locate workers in the event they are lost or incapacitated.
Passenger Information Display Systems
Piper Networks’ Passenger Information Display System (PIDS) powers the next generation of New York City Subway Countdown Clocks. The Metropolitan Transit Authority (MTA) adopted Piper Networks’ Bluetooth beacon technology on over 4,000 train cars to calculate and predict train arrival information. The result is that subway riders at 269 stations on the lettered lines can now better plan their travels.
