空间科学任务协同设计论证存在设计方案耦合强,数据一致性差,数据变更难,数据与流程脱节等问题.为了解决上述问题,建立了典型空间科学任务的多层数字化模型;采用图形化方式对论证流程进行建模,并建立流程与数据的映射关系;通过共享数据池的方式为多岗位用户提供多方案数据协同机制;采用消息总线对数据变更进行及时提醒;利用方案依赖关系矩阵来判别方案耦合关系,最终自动合并任务总体设计方案.作为一个分布式平台,空间科学任务协同设计平台采用Eclipse RCP和Spring技术架构,整合了Hibernate、工作流Activiti5等中间件,提供统一门户,支持多岗位、多任务、多方案、多版本的管理能力,提供论证流程监控、数据协同交互等功能.结合某空间科学任务论证验证了该平台的有效性.
In order to solve the above problems, a multi-layer digital model of typical space science tasks has been established in this dissertation, which is a combination of strong coupling of design schemes, poor consistency of data, difficulty of data changing, Process, and establish the mapping relationship between process and data; provide multi-scheme data collaboration mechanism for multiple posts by way of shared data pool; use message bus to promptly remind data changes; use scheme dependency matrix to determine scheme coupling Relationship, and ultimately the overall task of automatic merger design.As a distributed platform, space science task collaborative design platform using Eclipse RCP and Spring technology architecture, integration of Hibernate, workflow and other middleware Activiti5, to provide a unified portal to support multiple jobs, and more Tasks, multi-program, multi-version management capabilities, provide proof of process monitoring, data collaboration and other functions.According to a space science mission demonstration to verify the effectiveness of the platform.
