[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.
