The automatic level crossing warning system and method integrates with the train's tail signal device.

Abstract

This invention relates to an automated warning system and method at level crossings, integrating a train tail signal device. This system combines level crossing warning and train monitoring functions into a streamlined structure, comprising: a device installed on the locomotive (LDC), a device installed at the aft (MCDT), and a device in the level crossing area (TBDN). A unique feature of the invention is the use of real-time coordinates from the MCDT to terminate the warning at TBDN when the distance reaches a threshold error, which increases over time, thereby enhancing safety even in the event of a broken mooring hook. The system according to the invention is designed with a distributed communication architecture, allowing devices to exchange information directly over a long-range wireless network without the need for intermediate stations, ensuring stable operation even if one component fails. The invention not only optimizes infrastructure but also increases flexibility, reduces investment costs, and enhances safety and centralized management efficiency for the railway industry.
