LOCALIZATION METHOD FOR DETECTING OBSTACLES IN FRONT OF MOVING TRAINS BASED ON MODERN LiDAR TECHNOLOGY

Abstract

Currently, one of the urgent problems facing Uzbekistan Railways JSC is
localizing the method for detecting obstacles in front of moving trains using modern
LiDAR technology. Railway station platforms, tracks, and intersections are among
the main safety issues on the railways. Regrettably, preventable collisions claim
the lives of hundreds of people each year. Often, these incidents take place in the
previously mentioned railway areas. This article explores the use of modern LiDAR
technology to identify passengers at railway facilities and warn both locomotive
operators and passengers of potential danger. It also addresses the localization
of obstacle detection in front of moving trains using this technology. The WT200A
laser sensor is applied as the main component of the LiDAR system. This sensor is
capable of long-range detection – up to 200 meters – and utilizes laser beams with
a wavelength of 905 nanometers. It ensures high-accuracy operation even under
various weather conditions such as fog, rain, or snow. The WT200A sensor can
rapidly detect obstacles on railway tracks and send hazard warnings to the train
dispatcher, thus playing a critical role in enhancing railway safety.
