Automatic Train Dynamic Inspection Station

Operating Principle
The Automatic Train Dynamic Inspection Station is used to perform the dynamic inspection of any type of train’s wheels while passing in motion on the system without needing any operator. The system operates with non-contact measurement methods (such as laser and ultrasonic technologies), and records every train passes with an historic dedicated to each train’s wheel in its software database. Thanks to the RFID technology, the system is able to associated the data measured and calculated by the software with the train number associated to this automatic equipment identification (AEI). The system is always on sleep mode and only turns on when a train is about to pass on the system.
Integrated Systems
There are a lot of possible systems which can be part of the Automatic Train Dynamic Inspection Station. The commonly integrated systems used are:
  • Wheel profile gauge, which uses laser-camera technology to measure wheels with multiple-line lasers and high-speed cameras,
  • Optical wheel flaw detection, which uses multiple cameras to capture images of wheel circumference to observe and evaluate tread defect and flaw conditions,
  • Flat spot and out-of-round detection, which detects wheel anomalies with a low speed tread plate configuration,
  • Brake pad monitoring, which uses laser-camera technology to measure disc brake thickness with a set of measurement bays each consisting of a single-line laser and a high-speed camera.
Installation Details
The Automatic Train Dynamic Inspection Station is a real modular system since one or as much as you want integrated system can be part of it. The system can be done indoor or outdoor according to your needs. It can be placed in the middle of nowhere on the tracks, or it can have its own infrastructure in a maintenance depot. We don’t recommend putting this system indoor in a building with other systems since the sensors are very sensitive. The system doesn’t require much space as everything is installed directly on the tracks with the cabinet (electrical and computer) nearby. The system doesn’t require much maintenance other than yearly calibration and controls, and cleaning of the cameras & lasers on a regular basis.
