Technique: Thermography inspection via trackside infrared detector arrays

Development of a Trackside continuous monitoring system prototype for inspection of hotspots on wheel rim and axle bearing box

Result: A working prototype thermography trackside inspection system.

The trackside thermography inspection system concept has been proven by ISQ. The data acquisition system is a commercially available unit so it is the software and the electronics at the sensor end which add value to future exploitation. A unique aspect about the system is that it uses an array of infrared sensors as opposed to a thermography camera. This makes the system significantly cheaper compared to existing commercially available hot spot detection systems.

Developed Features:

• Infrared array
• LabView controlled DAS and events and alarm database
• Low hardware cost
