Application Research on the Multi-level Layout of Intelligent Security System in Large High-Speed Railway Hubs—A Case Study of Chengdu Tianfu Station

Large high-speed railway hubs, as critical urban nodes with dense passenger flow and convergence of multiple transportation modes, require their security systems to meet the full-dimensional needs of “physical protection, technical monitoring, emergency response, and collaborative management.” Taking Chengdu Tianfu Station as the research object, this paper systematically analyzes the multi-level layout logic of the intelligent security system from four dimensions: “physical security layer, technical security layer, emergency security layer, and management security layer.” The research shows that Tianfu Station has constructed a security system covering the entire process of “pre-event warning - in-event handling - post-event tracing” through a design path of “structural protection as the foundation, intelligent technology as the core, emergency linkage as the pulse, and integrated management as the soul”: The physical layer relies on fire compartments and anti-collision facilities to build solid safety barriers; the technical layer achieves intelligent monitoring through FAS, power remote control, and video interface reservations; the emergency layer focuses on evacuation lighting and emergency power supply to ensure personnel safety; the management layer utilizes cross-system collaboration to optimize the dispatch of security resources. This layout adapts to the characteristics of large hubs such as “high passenger flow, multiple interfaces, and long operating hours,” and the technical implementation details can provide references for similar projects.
