摘要
为提高分布、异构、动态网络环境下的空间数据协作效率,引入移动智能体计算技术构建空间信息共享服务.通过分析移动智能体技术的特点及应用于空间信息服务的优势,构建了基于四层体系的空间信息服务框架,设计了基于移动智能体技术的服务系统功能结构,并建立了移动智能体计算动态控制模型.最后,以堰塞湖溃决风险评估的分布式协同服务系统为例,给出了移动智能体计算的实现方法.研究结果表明,移动智能体计算可以避免空间数据在网络中传输,保障数据安全,提高数据协作效率.
To improve the efficiency of geospatial data cooperation under distributed,heterogeneous and dynamic environments,the mobile agent（MA） technology was used to construct geospatial information sharing service（GISS）.The characteristics of the MA technology and the advantages of its application to GISS were discussed.A four-layer service framework and a function structure based on the MA technology were designed,and a dynamic control model of MA computing was established.In addition,implementing method of MA computing was given by taking a distributed service system of the risk assessment of barrier-dam break as an application example.The research results show that the mobile agent computing can avoid the transmission of spatial data in the network,enhance data security and improve the efficiency of data cooperation.
