Research On Technologies Of Business Process Management For Remote Sensing Satellite Ground Information Processing

With the increase of on-orbit satellite number and rapid changes in business requirements, the size of the ground system is becoming larger and larger, thus bringing to the ground system a lot of problems on business process management. To solve the problems of business process management in ground infromation processing : difficult to support flexibly configuring of business process, difficult to implement the callback in the movement of business process, difficult to achieve the expansion of functional components, difficult to realize rapidly reconstructing of functional components, the business process management technology of the remote sensing satellite ground infromation processing is studied in this paper, the main research results include the following aspects:1. Business process management framework model of remote sensing satellite ground infromation processing.Firstly the business process of the remote sensing satellite ground infromation processing is analyzed, the problems of business process management existed in sensing satellite ground infromation processing are also analyzed. To solve the problems, based on the method of SOA the framework of business pocess management for sensing satellite ground infromation processing is established in this paper, and business modules are hierarchically designed, finally characteristics of the framework model are analyzed.2. Business process runtime callback technology of remote sensing satellite ground infromation processing.To solve the problem of business process runtime callback in remote sensing satellite ground infromation processing, multiple scenarios of business process callback are analyzed, business process model is established, and the model contraint rules which are adapted to the business process callback are given, then the callback target activity acquisition algorithm and the callback execution algorithm are proposed, finally based on the open source workflow engine Activiti the two algorithms are implemented and verified.3. Business services dynamic composition invocation technology oriented remote sensing satellite ground infromation processing application integration.Firstly problem of the business services dynamic composition invocation is described, then two kinds of application integration models in ground infromation processing are analyzed. The framework of business services dynamic composition invocation is established, the model of business services dynamic composition invocation is proposed, finally based on the open source ESB engine Mule ESB the dynamic composition invocation controller is realized, experiments prove the correctness of the framework and model of the business services dynamic composition invocation.4. Remote sensing satellite ground infromation processing verification prototype platform.Based on the above research work, the ground infromation processing verification prototype platform is designed and implemented, the framework ?technical methods proposed in this paper are verified in the prototype platform.
