【摘要】：随着液体火箭发动机研制和交付要求的提高,试验任务急剧增加、试验安全和质量精细化管理要求越来越高,发动机研制对试验系统规模、数据采集分析能力的要求大幅提高,试车数据也急剧增加,这些数据的存储问题已经成为不得不面对的巨大挑战。另一方面,试车后的数据利用率过低,大量的测试数据都没有进行全面分析。本文提出了一种基于开放式数据服务的试验数据管理系统,一方面要解决试车数据的存储问题,另一方面要充分分析及利用试车后的测试数据。本文首先对试验数据管理系统的理论基础进行了深入研究,根据系统的特点对开放式服务总线以及试验数据管理基础理论进行了探索。然后介绍了试验数据管理系统的关键技术,针对数据库的数据模型没有统一的标准,提出了基于ODS的液发数据应用模型,有效的解决了数据模型不统一的问题。针对关系数据库的数据库必须单独定义一套物理存储格式来完成标准化数据存储,本文借助于ODS制定了关系数据库的内部存储规范,包括:要哪些表,要存储哪些信息、哪些是主键等。并且只要实现数据模型和接口就能实现数据存取,而不必考虑物理存储格式规范,有效的解决了物理存储格式必须统一的问题。最后,针对液体火箭发动机试验数据处理问题,开发了基于开放式服务的液体火箭发动机试验数据管理系统。系统包括试验任务综合管理及进度监控、试验流程管理、异地数据自动化收集、基于动态数据库的集中存储、数据展现及处理以及系统管理的相关开发和实现。本文在理论基础研究上做了多方面的关键技术探讨,特别是对开放式数据服务的研究上做了深入研究,这对试验数据管理系统的设计及实现奠定了坚实的基础。系统的研制成功,满足当前液体火箭发动机繁重试验任务和我所快速发展需要,适应未来航天技术发展要求与趋势,为加快我国军工企业试验数据管理信息化步伐有重要的现实意义。
[Abstract]:With the development and delivery of liquid rocket engine, the test task increases rapidly, the test safety and quality fine management requirements are higher and higher, the test system scale, data acquisition and analysis ability requirements are greatly increased in engine development. Test-run data has also increased dramatically, and the storage of these data has become a huge challenge that has to be faced. On the other hand, the data utilization is too low after the test run, a large number of test data are not fully analyzed. In this paper, an open data service based test data management system is proposed. On the one hand, the storage of test data should be solved; on the other hand, the test data should be fully analyzed and utilized. In this paper, the theoretical basis of the experimental data management system is studied, and the open service bus and the basic theory of experimental data management are explored according to the characteristics of the system. Then the key technology of the test data management system is introduced. Aiming at the lack of unified standard of the data model of the database, the application model of liquid sending data based on ODS is put forward, which effectively solves the problem that the data model is not unified. The database of relational database must define a set of physical storage format separately to complete the standardized data storage. This paper formulates the internal storage specification of relational database with the help of ODS, including: which tables to store, what information to store, Which are primary keys and so on. As long as the data model and interface are implemented, the data access can be realized without considering the physical storage format specification, which effectively solves the problem that the physical storage format must be unified. Finally, a liquid rocket engine test data management system based on open service is developed to deal with the problem of liquid rocket engine test data processing. The system includes test task management and schedule monitoring, test flow management, remote data automatic collection, centralized storage based on dynamic database, data presentation and processing, and related development and implementation of system management. In this paper, several key technologies are discussed on the theoretical basis, especially the open data service, which lays a solid foundation for the design and implementation of the experimental data management system. The system has been successfully developed to meet the heavy test tasks of liquid rocket engines and the rapid development needs of our institute, and to meet the requirements and trends of the future space technology development. In order to speed up the pace of information management of military enterprises' test data, it has important practical significance.
