为解决多源遥感卫星数据快速共享过程中异地和异构数据集成、实时交互数据监控和业务流程动态更新问题,提出了基于应用层、逻辑层、支撑层和数据层的4层软件架构体系.在实际软件架构设计中,采用基于JEE6框架的面向服务架构体系,并引入分布式工作流技术来搭建调度系统的服务器端软件；同时,搭建基于Socket协议的客户端来实现与服务器端的实时通信,以便于监控系统中交互数据的状态.从而形成了混合结构(浏览器/服务器、客户端/服务器)下处理多源、异地和异构遥感数据快速共享的集成软件架构体系.经过实验室模拟仿真运行和实际环境试运行结果来看,本软件系统架构能够满足多用户对多源异构遥感数据快速请求服务的需求,有效地实现了对多源异构遥感数据的综合处理,提高了系统数据访问的安全性.%A four-layer software architecture based on application layer, logical layer, supported layer, and data layer was put up, in order to solve the problems integrating remote and heterogeneous data , monitoring real-time and interactive data, and updating the business process dynamically in the process of sharing multi-source remote sensing data quickly. In the real application, the software architecture based on SOA using JEE6 framework was used to build up server software of the scheduling system through adopting distributed workflow technology, at the same time, the client software based on Socket Protocol was also designed to communicate with server instantaneously so as to monitor the station of interactive data. Finally, an integrated software architecture based on composite construction (Browser/Server, Client/Server) come into being to deal with the sharing problems of multi-source, remote and heterogeneous remote sensing data. After the testing between the laboratory simulation and actual environmental, the experimental results show that the proposed software system architecture can satisfy the fast multi-source heterogeneous remote sensing data querying requests for many users, and it also can effectively realize the integrated multi-source remote sensing data processing, improving the security of the system data access.
