AI Technical Summary
Technical Problem
[0002]在现代城市治理体系中，多政府机构协同管理公共设施已成为提升公共服务效能的关键环节，交通局、环保局等部门需频繁共享桥梁结构健康度、垃圾处理站运行状态等关键数据，此类数据由部署在广域地理空间的物联网传感器实时生成，具有显著的时空动态特性，为实现数据高可用性，各机构通常采用异构云平台独立存储多副本数据，形成分布式数据孤岛，与此同时，外部网络攻击威胁持续升级，欧盟通用数据保护条例等国际合规性要求日益严格，迫使数据共享过程必须嵌入高强度加密机制，然而，公共设施异常监测需求（如桥梁裂缝演化分析）要求对加密数据实施毫秒级响应分析，现有技术体系难以兼顾数据隐私安全与实时性需求，严重制约跨部门协同治理能力
Benefits of technology
[0014]本发明的有益效果是：该方法有效融合区块链加密验证与联邦学习机制，在保护多机构数据隐私前提下构建加密时空图模型，通过动量加权优化与轻量化图推理实现高效异常检测；通过引入抗量子投影与多云并行计算显著提升分析实时性，结合时空感知噪声注入与可验证灾备同步技术，在确保差分隐私强度的同时精准捕捉设施异常状态，最终通过智能合约驱动的分级告警机制实现跨部门协同响应，形成安全可靠、精准高效的公共设施闭环治理能力。

Abstract
The application relates to a public facility abnormal data processing and analysis method based on a space-time graph neural network, and particularly relates to the field of public facility abnormal data processing and analysis. The method effectively fuses a blockchain encryption verification and a federal learning mechanism, constructs an encrypted space-time graph model under the premise of protecting the data privacy of multiple institutions, realizes efficient abnormal detection through momentum weighted optimization and lightweight graph reasoning, significantly improves analysis real-time performance by introducing anti-quantum projection and multi-cloud parallel computing, combines space-time perception noise injection and a verifiable disaster backup synchronization technology, accurately captures facility abnormal states while ensuring differential privacy strength, and finally realizes cross-department collaborative response through a hierarchical alarm mechanism driven by a smart contract, thereby forming a safe, reliable, accurate and efficient public facility closed-loop management capability.
