Research on the Construction of a Low-Altitude Security System for Major Event Security

Abstract

With the opening of low-altitude airspace and the proliferation of drone technology, low-altitude security has become a critical component of the security system for major events. Addressing the diversified and dynamic characteristics of contemporary low-altitude threats, this paper systematically constructs a low-altitude security system for major event security. By defining the conceptual connotation and layered architecture of the low-altitude security system, it proposes a core model based on Cyber-Physical Systems and system resilience theory. The paper further analyzes the classification characteristics and behavioral patterns of multi-source, heterogeneous low-altitude threats, establishing a dynamic risk assessment framework that incorporates spatiotemporal constraints. Building upon this foundation, it designs a technical pathway for collaborative perception and intelligent response via a multi-dimensional sensor network, enabling closed-loop management from threat detection to response decision-making. The research demonstrates that this system can significantly enhance the real-time perception capability, risk assessment accuracy, and response efficiency regarding low-altitude threats, providing theoretical support and technical solutions for low-altitude security during major events.
