Pantograph Monitoring Application

Pantograph Monitoring Application

The Pantograph Monitoring application from Noema uses smart cameras and computer vision to monitor train pantographs, drastically reducing pantograph-related maintenance costs and overhead wire damage. The app automatically monitors the overhead wires and the pantograph head, checking for positioning and sparking, and sends alarms for these events. Noema’s Pantograph Monitoring application generates easily digestible metadata that can be integrated into any backend or VMS.

Noema apps operate at the edge, meaning computing is done on the camera itself, with no additional hardware required. Noema’s Pantograph Application is more cost effective and accurate than a human monitor.

The Problem

A single delayed train costs $45,000 USD on average, and incidents of wire damage from pantographs can cost rail companies upwards of $1 Million USD annually. Many pantograph related accidents are commonly due to incorrect positioning of the pantograph leading to sparking and further damage. Detecting anomalies before damage occurs drastically reduces the costs of monitoring and maintenance for pantograph-equipped train systems.

Solution Advantages

Automated, 24/7 monitoring

The Pantograph Monitoring App runs 24/7 and detects events with more consistency and accuracy than a human operator. Continuous pantograph monitoring is nearly impossible using human operators and automatic monitoring and alarms help further-reduce maintenance costs and response times.

Computing at the Edge

Noema’s Pantograph app operates at the edge, meaning the algorithm runs entirely on the camera. No additional hardware or network connectivity required.

Remote Installation & Configuration

Noema’s computer vision applications are easy to install. Mount a new camera or equip an existing one and configure the application remotely over the internet. No additional on-site hardware or measurements are required.
