To support the construction of the low-altitude intelligent connected system, address core issues such as diverse operational scenarios, varying safety risks, and mismatched capability configurations in the large-scale development of the low-altitude economy, and promote the safe, controllable, scaled, and intelligent development of the low-altitude economy, based on the Low-Altitude Intelligent Connected System Reference Architecture (2024 Edition) and relevant policy guidance, a construction method for the low-altitude intelligent connected system with "scenario-driven, risk classification, capability mapping, and technology iteration" as the main line was established by analyzing the core challenges of low-altitude economic development. Additionally, a "six-step closed-loop" implementation process was constructed, encompassing operational scenario analysis, operational mode design, acceptable safety level assessment, required capability analysis, technical scheme design, and system integration and verification iteration. On this basis, a technical route featuring "risk-driven, capability-oriented, multi-party collaboration, and iterative evolution" was formed. The research results show that the proposed construction method and implementation process can achieve accurate matching between safety risks and system capabilities, and the technical route can effectively adapt to the needs of multi-scenario low-altitude operations. The research provides theoretical basis and practical guidance for the hierarchical construction, capability configuration, and continuous evolution of the low-altitude intelligent connected system and can effectively promote the large-scale and intelligent development of the low-altitude economy under the premise of safety and controllability.
