摘要

随着城市基础设施建设的不断发展，综合管廊作为城市地下管网的集中载体，承载着电力、通信、供水等多种城市功能。如何确保管廊的安全运行成为了城市管理中的关键问题。基于数字孪生技术的安防系统，通过实时监控、数据融合、虚实联动等手段，为综合管廊提供了智能化的安全保障方案。该系统通过数字孪生模型精确复刻管廊实体，结合虚拟仿真与物理系统的双向互动，实时预警、精准定位潜在风险，提升了管廊的防护能力与响应效率。此种机制不仅优化了管廊安防管理流程，还增强了城市基础设施的韧性，推动了智慧城市的发展。

Abstract

With the continuous development of urban infrastructure, utility tunnels serving as centralized conduits for underground pipelines now carry critical urban functions including power supply, telecommunications, and water distribution. Ensuring their safe operation has become a pivotal challenge in urban management. The security system based on digital twin technology provides intelligent safety solutions through real-time monitoring, data integration, and virtual-real interaction. By accurately replicating physical tunnels through digital twin models and enabling bidirectional interaction between virtual simulations and physical systems, this approach enables real-time risk alerts and precise hazard detection, significantly enhancing tunnel protection capabilities and response efficiency. This mechanism not only optimizes security management processes but also strengthens the resilience of urban infrastructure, driving the advancement of smart cities.
