| Abstract |
Steelworks present challenging environments for conventional train control systems due to high temperatures, dust, and limited visibility. This study proposes a GNSS RTK-based train control system that integrates high-precision positioning with wireless communication and evaluates its performance through on-site experiments. The proposed system combines RTK positioning data with wheel sensors and track occupancy information to ensure reliable control at key locations such as stop signals and level crossings.
Test results demonstrate that the system effectively follows speed limits and braking curves, even under manual driving conditions, and that the control logic operates reliably in real industrial settings. Additionally, in GNSS-denied areas, the system maintains position continuity through supplementary sensor data. These findings confirm the system's applicability in environments where ground equipment installation is limited. |
