Application Case

Rail Transit

1.Device function overview

By deploying high-speed industrial cameras and infrared cameras on the roofs of urban rail trains, online detection of the catenary and pantograph (on the side of the bow) under train operation is performed, and the contact network is discovered in time using the temperature analysis function of the infrared camera Pantograph (potential) electrical faults, synchronized high-definition visible light pictures, can timely find electrical faults and defects on pantograph, catenary, support suspension surface, and real-time detection of dynamic geometric parameters of catenary with the help of image recognition technology. Real-time alarm is provided to realize the dynamic online detection function of contact network and pantograph under train operation status.
Integrated positioning information for the entire inspection data (provided by the PIS system) to meet the requirements for the positioning and searching of inspection defect data; in addition, the inspection data is stored in sections by inspection interval and by inspection time to meet the requirements for management, exchange, use and detailed analysis of inspection data .
