随着低空智联网(Low-Altitude Intelligent Network,LAIN)在智能交通、环境监测和公共安全等领域的广泛应用,低空经济得到快速发展。然而,随着无人机(Unmanned Aerial Vehicle,UAV)和其他空域设备数量的激增,数据源的多样性和复杂性等挑战日益显现,尤其是信息异构性、实时处理需求以及安全风险的管理,成为影响LAIN高效运作和安全保障的关键问题。为了应对这些挑战,设计并实现了一个安全态势认知系统,能够高效整合多源数据并进行实时分析与风险预警。系统首先分析了LAIN数据来源的异构特性,并提出了有效的数据采集与预处理策略。然后结合多接入设备,构建了一个多维数据融合框架,实现了数据的高效整合与统一表征。通过高级威胁检测技术,系统实现了潜在风险的实时识别与预测,通过复杂空域管理中的无人机轨迹预测与风险预警应用验证了系统的有效性。最后,总结了系统面临的挑战,并展望了未来在安全性和智能化方面的研究方向。

The rapid development of the low-altitude intelligent network (LAIN) significantly enhances its applications in smart transportation, environmental monitoring, and public security, driving the growth of the low-altitude economy. However, the increasing number of unmanned aerial vehicle (UAV) and other aerial devices introduces substantial challenges. These include the diversity and complexity of data sources, information heterogeneity, the need for real-time processing, and escalating security risks, which pose critical barriers to the efficient operation and secure management of LAIN. To address these challenges, the design and implementation of a security situation cognitive system was presented that could efficiently integrate multi-source data and support real-time analysis and risk warning. The system first analyzed the heterogeneity of data sources in LAIN and proposed effective strategies for data collection and preprocessing. It incorporated a multi-dimensional data fusion framework, leveraging the multi-access devices to achieve efficient data integration and unified representation. Utilizing the advanced threat detection technologies, the system realized real-time risk identification and prediction. Its effectiveness was demonstrated through applications such as UAV trajectory prediction and dynamic risk assessment in complex airspace management scenarios. Finally, the challenges the system faced during implementation were discussed and the insights into future research directions were provided to further enhance the security and intelligence capabilities of LAIN.
