摘　　要：传感设备实时数据已经逐步成为GIS对现实世界动态特征表达与时空大数据分析的主要数据来源之一。将传感设备与全空间信息系统结合,提出一种面向全空间信息系统的传感设备动态接入与感测数据流式管理架构。基于多粒度时空对象描述框架对传感设备进行动态时空建模,实现传感设备的动态接入与时空对象化一体管理;设计可伸缩的实时数据管理系统体系;引入任务驱动的感测数据流式处理机制;通过实验验证数据管理架构的技术可行性。Real-time data of sensing equipment has gradually become one of the main data sources for GIS to express the dynamic characteristics of the real world and for spatio-temporal big data analysis.The sensor equipment is combined with the pan-spatial information system,and a kind of sensing equipment streaming data management architecture is proposed.Based on the multi-granularity spatio-temporal object description framework,sensing equipment is modeled as a type of spatio-temporal object.Dynamic access of sensing equipment is realized in PSIS,and the sensed data can be integrated managed with other spatial-temporal data.The scalable real-time data management system is designed,the task-driven streaming data processing mechanism is induced,and the technical feasibility of the data management architecture is verified by experiments.
