【摘要】：隨著液體火箭發(fā)動(dòng)機(jī)研制和交付要求的提高,試驗(yàn)任務(wù)急劇增加、試驗(yàn)安全和質(zhì)量精細(xì)化管理要求越來越高,發(fā)動(dòng)機(jī)研制對(duì)試驗(yàn)系統(tǒng)規(guī)模、數(shù)據(jù)采集分析能力的要求大幅提高,試車數(shù)據(jù)也急劇增加,這些數(shù)據(jù)的存儲(chǔ)問題已經(jīng)成為不得不面對(duì)的巨大挑戰(zhàn)。另一方面,試車后的數(shù)據(jù)利用率過低,大量的測試數(shù)據(jù)都沒有進(jìn)行全面分析。本文提出了一種基于開放式數(shù)據(jù)服務(wù)的試驗(yàn)數(shù)據(jù)管理系統(tǒng),一方面要解決試車數(shù)據(jù)的存儲(chǔ)問題,另一方面要充分分析及利用試車后的測試數(shù)據(jù)。本文首先對(duì)試驗(yàn)數(shù)據(jù)管理系統(tǒng)的理論基礎(chǔ)進(jìn)行了深入研究,根據(jù)系統(tǒng)的特點(diǎn)對(duì)開放式服務(wù)總線以及試驗(yàn)數(shù)據(jù)管理基礎(chǔ)理論進(jìn)行了探索。然后介紹了試驗(yàn)數(shù)據(jù)管理系統(tǒng)的關(guān)鍵技術(shù),針對(duì)數(shù)據(jù)庫的數(shù)據(jù)模型沒有統(tǒng)一的標(biāo)準(zhǔn),提出了基于ODS的液發(fā)數(shù)據(jù)應(yīng)用模型,有效的解決了數(shù)據(jù)模型不統(tǒng)一的問題。針對(duì)關(guān)系數(shù)據(jù)庫的數(shù)據(jù)庫必須單獨(dú)定義一套物理存儲(chǔ)格式來完成標(biāo)準(zhǔn)化數(shù)據(jù)存儲(chǔ),本文借助于ODS制定了關(guān)系數(shù)據(jù)庫的內(nèi)部存儲(chǔ)規(guī)范,包括:要哪些表,要存儲(chǔ)哪些信息、哪些是主鍵等。并且只要實(shí)現(xiàn)數(shù)據(jù)模型和接口就能實(shí)現(xiàn)數(shù)據(jù)存取,而不必考慮物理存儲(chǔ)格式規(guī)范,有效的解決了物理存儲(chǔ)格式必須統(tǒng)一的問題。最后,針對(duì)液體火箭發(fā)動(dòng)機(jī)試驗(yàn)數(shù)據(jù)處理問題,開發(fā)了基于開放式服務(wù)的液體火箭發(fā)動(dòng)機(jī)試驗(yàn)數(shù)據(jù)管理系統(tǒng)。系統(tǒng)包括試驗(yàn)任務(wù)綜合管理及進(jìn)度監(jiān)控、試驗(yàn)流程管理、異地?cái)?shù)據(jù)自動(dòng)化收集、基于動(dòng)態(tài)數(shù)據(jù)庫的集中存儲(chǔ)、數(shù)據(jù)展現(xiàn)及處理以及系統(tǒng)管理的相關(guān)開發(fā)和實(shí)現(xiàn)。本文在理論基礎(chǔ)研究上做了多方面的關(guān)鍵技術(shù)探討,特別是對(duì)開放式數(shù)據(jù)服務(wù)的研究上做了深入研究,這對(duì)試驗(yàn)數(shù)據(jù)管理系統(tǒng)的設(shè)計(jì)及實(shí)現(xiàn)奠定了堅(jiān)實(shí)的基礎(chǔ)。系統(tǒng)的研制成功,滿足當(dāng)前液體火箭發(fā)動(dòng)機(jī)繁重試驗(yàn)任務(wù)和我所快速發(fā)展需要,適應(yīng)未來航天技術(shù)發(fā)展要求與趨勢,為加快我國軍工企業(yè)試驗(yàn)數(shù)據(jù)管理信息化步伐有重要的現(xiàn)實(shí)意義。
[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.
