摘要 将Agent技术引入到分布式GIS领域 ,提出了一个面向分布式GIS的多Agent系统模型 ,为分布式GIS的研究和开发提供了一种新的方法 首先设计了系统的体系结构 ,将分布式GIS系统中的Agent分成三类 :Facilitator,GIS功能Agent和接口Agent,并给出了GISAgent的结构和特征以及Agent之间的通信机制 ;然后采用DCOM技术和多线程技术 ,实现了一个空间多Agent系统的原型 ,并对其中的关键技术 (同步技术、Agent的调度、Agent的强制终止等 ) Application of agent technology into distributed GIS is proposed, and a model of distributed GIS oriented multi agent system is presented It provides a new method to study and develop distributed GIS Firstly, the architecture of the system is designed, and GIS agent is categorized as three types: Facilitator, GIS function agent and interface agent The structure and features of GIS agent and the communication mechanism among GIS agents are also given Secondly, a prototype of spatial multi agent system is implemented based on DCOM and multi thread technologies The key techniques such as synchronization, agent scheduling, agent's forcible stop and spatial metadata, are explored and analyzed in detail
