1 Introduction
In the modernization of railway construction, railway safety is the primary issue that needs to be addressed. With the development of railway construction, the traditional method of rail inspection by track inspectors is no longer feasible on many newly built railway lines due to the long distances between stations. Furthermore, the significant increase in train speeds poses greater dangers to track inspectors. There is an urgent need to implement automated rail condition inspection to replace manual inspection. Because manual rail inspection is dangerous, inefficient, and prone to false positives, this paper utilizes National Instruments' LabVIEW virtual instrument development platform to design a LabVIEW-based rail damage detection system to facilitate the transition from manual to automated rail inspection.
