【摘要】：随着在轨卫星数量的增加以及业务需求的快速变化,遥感卫星地面系统的规模也在不断地扩大,因此给地面信息处理业务流程管理带来了许多问题。针对地面信息处理在业务流程管理中存在的难以支持业务流程的灵活配置、难以实现业务流程运行过程中的任意回退、难以实现功能组件的扩展、难以实现功能组件的快速重组等问题,本文对遥感卫星地面信息处理业务流程管理技术展开研究,主要研究成果包括以下几个方面:1、遥感卫星地面信息处理业务流程管理框架研究详细梳理了遥感卫星地面信息处理的业务流程,分析并描述了地面信息处理业务流程管理所存在的问题。为解决存在的问题,本文采用面向服务体系结构(Service Oriented Architecture,简称为SOA)的方法建立了遥感卫星地面信息处理业务流程管理框架,使用工作流和企业服务总线(Enterprise Service Bus,简称为ESB)技术对地面信息处理的业务模块进行分层设计,分析了框架的特点。2、遥感卫星地面信息处理业务流程运行时回退技术针对遥感卫星地面信息处理业务流程在运行过程中存在的流程回退问题,分析了业务流程回退的多个场景,建立了业务流程模型,给出了适应业务流程回退的模型约束规则。设计了业务流程回退目标活动获取算法和回退执行算法,基于开源工作流引擎Activiti实现并验证了本文设计算法的正确性。3、面向遥感卫星地面信息处理应用集成的业务服务动态组合调用技术描述了业务服务动态组合调用问题,分析了地面信息处理应用集成的两种模式。建立了一个业务服务动态组合调用框架,提出了一个业务服务动态组合调用模型,基于开源ESB引擎Mule ESB设计实现了调用控制器,实验验证了所提出业务服务动态组合调用框架模型的正确性。4、遥感卫星地面信息处理业务流程管理原型系统基于上述的研究工作,设计实现了遥感卫星地面信息处理业务流程管理原型系统,验证了本文提出的框架、技术方法。
[Abstract]:With the increase in the number of satellites in orbit and the rapid changes in operational requirements, the scale of the ground system of remote sensing satellites is constantly expanding. Therefore, it brings many problems to the business process management of the ground information processing, aiming at the flexible configuration of the business process which is difficult to support in the business process management of the ground information processing, it is difficult to realize the arbitrary fallback in the business process running process. It is difficult to realize the expansion of functional components and the rapid recombination of functional components. In this paper, the business process management technology of ground information processing for remote sensing satellites is studied. The main research results include the following aspects: 1. The research on the business process management framework of remote sensing satellite ground information processing detailed combs the business process of remote sensing satellite ground information processing. This paper analyzes and describes the problems existing in the business process management of ground information processing. In this paper, Service Oriented Architecture (SOA) is used to establish the business process management framework of remote sensing satellite ground information processing. The business module of ground information processing is designed by using workflow and enterprise service bus (ESBs) technology. This paper analyzes the characteristics of the framework. 2. In view of the problems existing in the operation process of remote sensing satellite ground information processing business process, the multi-scenarios of the business process back back are analyzed, which is aimed at the problem that the remote sensing satellite ground information processing business process is running back, and the operation process of remote sensing satellite ground information processing business process is running back. The business process model is established, and the model constraint rules for business process fallback are given, and the target activity acquisition algorithm and back-back execution algorithm are designed. Based on the implementation of open source workflow engine Activiti, the correctness of the proposed algorithm is verified. The dynamic combination invocation technology of business services for remote sensing satellite ground information processing application integration is described. This paper analyzes two modes of application integration of ground information processing, establishes a framework of dynamic composite call of business services, proposes a model of dynamic composite invocation of business services, and designs and implements a call controller based on open source ESB engine Mule ESB. The correctness of the proposed model is verified by experiments. 4. The prototype system of remote sensing satellite ground information processing business process management is based on the above research work. The prototype system of remote sensing satellite ground information processing business process management is designed and implemented, and the framework and technical method proposed in this paper are verified.
