How PANTOBOT 3D works

U
LED illuminator array

Powerful illuminators ensure reliable 24/7 image acquisition in all weather and lighting conditions. Long operational life minimises maintenance requirements.

U
Stereoscopic image capture

High-resolution stereoscopic camera acquires sharply focused, blur-free left and right close-up images of pantograph at train speeds of up to 350 kmh.

U
Laser telemeter

Pantograph and contact strip of passing train interrupts two closely-spaced low powered, eye-safe laser beams, providing information on train position, speed, and direction to ensure accurate triggering of stereoscopic camera.

U
Weather Station

Weather data collected and utilised in advanced wear algorithms.

U
Pantograph identification and classification

Machine vision camera system automatically reads carriage ID and links it with the pantograph being monitored.

U
Pantograph condition analysis

Powerful machine learning algorithms assess pantograph condition against criteria including contact strip condition (carbon wear and chipping), contact strip rotation, degree of uplift, contact with catenary, head orientation, orthogonality and defects in horn structure.

PANTOBOT 3D is the world’s first fully automated three-dimensional wayside pantograph inspection and monitoring system.

Deployed by rail operators across Europe, North America, and Asia, PANTOBOT 3D uses advanced imaging and machine learning to assess pantograph condition – safely, in real-time and without the need to withdraw trains from service.

PANTOBOT 3D delivers powerful insights into pantograph condition without the costs, service disruption, and safety risks of manual inspection. This allows operators to schedule predictive maintenance, dramatically reducing the danger of a damaged pantograph causing overhead line tear-downs that impact directly on operating revenues and service continuity.

3D PROCESSING

Left and right images from stereoscopic cameras are analysed and merged to create an accurate 3D model of the pantograph.

PANTOGRAPH CONDITION ANALYSIS

Powerful machine learning algorithms assess pantograph condition against criteria including contact strip condition (carbon wear and chipping), contact strip rotation, degree of uplift, contact with catenary, head orientation, orthogonality and defects in horn structure. 

Pantograph parameters exceeding threshold values will trigger automated alarm.

PANTOBOT 3D advantages and benefits for train network operators

Manual inspection imposes safety risk on maintenance staff needing to manually access top of carriage/power car


PANTOBOT 3D
advantage

Monitoring of pantograph/contact strip is totally automated, eliminating safety risks to workforce of manual inspection

Manual inspection may not give fully accurate, repeatable results


PANTOBOT 3D
advantage

Fully automated pantograph inspection workflow provides consistent, highly precise monitoring data

Overhead line tear-down caused by worn or misaligned pantograph contact strip can impact service continuity, customer revenues and operational reputation.


PANTOBOT 3D
advantage

Reduced risk of teardown ensures optimised service continuity and revenue retention

Manual pantograph inspection requires taking train out of service


PANTOBOT 3D
advantage

Fully automated, real-time wayside inspection maximises availability of rolling stock

Operators require accurate understanding of true condition of pantograph assets to support scheduled maintenance and fleet optimisation


PANTOBOT 3D
advantage

Accurate monitoring, tracking, and trending of pantograph condition for the entire fleet enables more efficient predictive maintenance strategies

Safe, accurate real-time wayside inspection
