城市防灾应急信息数据同步整合系统优化设计

传统基于物联网技术的灾害信息分析系统,采用多个传感器实时获取城市灾害数据,缺乏灾害信息的同步整合过程,用户难以实时获取系统性的城市灾情信息。对城市防灾应急信息数据同步整合系统进行优化设计,采用基于数据仓库的决策支持系统(DSS)作为核心体系设计系统总体结构;通过信息采集模块、信息处理模块、信息输出模块完成系统硬件设计;利用灾情数据计算模型获取建筑物破坏状态信息与经济损失数据,在此基础上将OLAP技术与Web结合,完成城市灾情信息同步整合,实现城市防灾应急信息数据同步整合系统的优化设计。实验结果表明,所设计系统信息查询响应时间约为1.2 s,可靠性均值为97%,能够快速、有效实现城市防灾应急信息数据同步整合。

Optimization Design of Data Synchronization and Integration System for Urban Disaster Prevention and Emergency Response

The traditional disaster information analysis system based on the Internet of Things (IOT) technology uses multiple sensors to obtain real-time urban disaster data,lacking the synchronous integration of disaster information,and it is difficult for users to obtain systematic urban disaster information in real time.The data synchronization integration system of urban disaster prevention and emergency is optimized,and the decision support system (DSS) based on data warehouse is used as the core system to design the overall structure of the system.On the basis of taking the damage state information and economic loss data of buildings,combining OLAP technology with Web,the synchronous integration of urban disaster information is completed,and the optimal design of the synchronous integration system of urban disaster prevention and emergency information is realized.The experimental results show that the response time of the system is about 1.2s and the average reliability is 97%.It can realize the data synchronization of urban disaster prevention and emergency information quickly and effectively.
