Abstract
A dynamic detection technology for the irregularity state of railway track by means of linear array CCD sensor is introduced, and the detecting method, the structure of the system are also described in detail. In this paper, a model of 2-meter chord measuring method is established; the digital inverse filter is analyzed and simulated to get the irregularity state of railway track. The analysis and Summary about how to apply the inverse filter are given. Finally some experiment result and detection data are given from the depot.
