Analyzing the Distance between Metallic Markers in Position Detection Sensors of Railway Vehicles

Abstract

The position information for railway vehicles is encoded by the position detection sensor by analyzing the multiple metallic markers placed on railway tracks these markers are detected using on-board equipment. This enables position detection for railway vehicles. However, the optimal distance between these metallic markers considering lift-off and rail displacement has not yet been studied. Therefore, we evaluated the effect of sensor misalignment on detection sensitivity. We examined the placement distance between the metallic markers and found that the best encoding is achieved when the placement distance is 300mm.
