Automatic Wayside Brake Shoe Inspection system

BrakeView-Shoe is a wayside brake shoe (Block) Measurement system designed to inspect brake shoes at track speeds. This system is vision-based and uses a multi-camera high speed imaging unit to take multiple images of every brake shoe for inspection and measurement.

BrakeView enclosures are installed on two short towers, one in each side of track, mounted on two concrete or steel footings. Cameras and illumination systems are installed in a safe distance from the center of the track. Since the brake shoe is viewed by two cameras, a complete and reliable assessment of the brake shoe condition is provided.
Brake shoes are viewed from top and bottom perspectives. Acquired images are processed by a set of sophisticated image processing algorithms. The imaging system and processing algorithms are designed to be insensitive to ambient light conditions and can operate in both day and night time conditions.

Brake shoe data is integrated into TrainDB database system with possible web-based data access, including images. This data can be used in ECP train monitoring where brake shoe and wheel profile data are both needed.
