Abstract

This paper synthetically analyzes several kinds of optical measurement methods of rail wear. A new measuring method and its systematic structure, which realizes automatic measurement of the wear on rail profile, was emphatically elucidated. It was implemented by means of adopting a kind of positive sensitive photoelectric detector PSD, and based on the principle of optical triangle measurement, and using stepping motor for scan and controlled by micro-processor. It provides a new measuring method for monitoring and analyzing the state of railway track- rail and ensures the safe of railway.
