Rolling stock defects are a serious threat to railway safety, with increasing rail traffic and train operations, it has become very important to have a check on the health of rolling stock to identify the defects which may leads to serious accidents. Increased rail traffic density has made the manual inspection a tedious job. Moreover, the manual inspection methods of wheel profile (or wheel defects) measurements are based on high human intervention resulting in higher labour cost, poor repeatability and manual errors.
The Wheel Data Acquisition System-WPMS-1 also known as Wheel Profile Measurement System is a solution that scans the wheels of moving trains. The system is designed to measure the different parameters of the moving wheels, to prevent failure due to excessively worn wheels at early stages as well as increase the life operations of wheels by addressing defects at an early stages.
The profile generated by the scanner is processed by the software and the following listed parameters including wheel gauge (if required) can easily be calculated automatically.
