Construction of the Unmanned Level Crossing Management System at the Pingxiang Track Maintenance Section of the Nanchang Railway Bureau
Project Background
The Pingxiang Track Maintenance Section of the Nanchang Railway Bureau oversees a network of branch lines characterized by long track lengths and a large number of unguarded level crossings. Along these routes, intersections with township and rural roads are densely concentrated, while trees and structures near the crossings obstruct visibility, and road surface facilities are aging and deteriorating. These conditions give rise to significant safety hazards, including drivers attempting to dash across crossings and pedestrians illegally crossing the tracks.
The original control model relied solely on manual, periodic inspections, making it difficult to eradicate issues such as monitoring personnel leaving their posts or failing to perform their duties adequately. It also lacked integrated technical safeguards for early train warnings, automated on-site protection, and intelligent identification of abnormal behaviors. Meanwhile, China State Railway Group’s documents explicitly require unmanned level crossings to be equipped with train-approach alarm systems; however, conventional single-function monitoring devices cannot achieve a closed-loop process encompassing train detection, signal interlocking, and remote alerts, leaving the risk of collisions with non-railway users persistently high. To implement railway crossing safety management policies and address the shortcomings of human‑based oversight, the Pingxiang Track Maintenance Section partnered with Guilin SPEPC to deploy an unmanned railway crossing management system, establishing a digital demonstration pilot for unmanned level crossings.
Solutions and Deployment
-
AI-powered surveillance cameras: Detect unauthorized entry by people or vehicles, preventing potential threats before they occur.
-
Active axle-counting sensor: Monitors in real time the arrival, approach, arrival, and departure of trains, generating corresponding records.
-
Information Processing Host: Integrates computing, display, communication, and expansion into a single unit, offering robust data-processing capabilities and a rich array of interface configurations. It comprehensively meets the integrated control requirements of unmanned level-crossing automation—encompassing automated control, status monitoring, data communication, and equipment interoperation.
-
RTU data collector: Used to receive and process wheel‑axle signals transmitted by active axle‑counting sensors, enabling intelligent detection of train arrivals, approach, arrival, and departure, and interfacing with the information‑processing host for coordinated control, thereby enhancing the safety management efficiency of unattended level crossings.
-
Speaker: The core component of the railway crossing safety voice‑prompting system, it enhances safety management in crossing areas through clear audio alerts.
Implementation Effectiveness
The system implements tiered train‑level early warning, AI‑powered vehicle‑pedestrian recognition, and multi‑redundant, stable operation. Remote monitoring and control eliminate safety hazards at level crossings, significantly reducing the workload of manual inspections. Furthermore, leveraging a multi‑redundant architecture, it achieves fully automated protection at crossings, intelligently detects unauthorized intrusions, and enables centralized remote management, thereby eliminating off‑track safety risks at their source.
