    摘要:

    某大型风洞运行实时数据繁多,急需开发一套实时数据库管理系统来实现数据的采集、存储和管理功能,从而满足各类数据应用系统的数据使用需求。为降低项目研制风险,首先开发一套实时数据采存原型。通过对风洞实时数据进行梳理分类,结合各类数据采存需求,充分利用实时数据库、关系型数据库、DFS系统等多种存储方式,设计了包括现场全量级、数据中心级和统计分析级在内的三级采存架构原型。通过硬件系统搭建、软件功能开发调试,对采存原型的IOPS、采存实时性、数据检索速率和压缩率等关键性能指标进行了测试。测试结果表明:该实时数据采存原型能够满足大型风洞现场实时数据采存需求,有效降低了此类实时数据库管理系统开发的技术风险,为后续系统开发完善打下了良好的技术基础。

    Abstract:

    A large wind tunnel has a large amount of real-time data during operation, and there is an urgent need to develop a real-time database management system to achieve data collection, storage, and management functions, in order to meet the data usage needs of various data application systems. To reduce project development risks, first develop a real-time data acquisition and storage prototype. A three-level storage architecture prototype was designed, including on-site full scale, data center level, and statistical analysis level, by classifying 风洞 real-time data and combining various data storage requirements, fully utilizing various storage methods such as real-time databases, relational databases, and DFS systems. Through hardware system construction, software function development and debugging, key performance indicators such as IOPS, real-time performance, data retrieval rate, and compression rate of the storage prototype were tested. The test results show that the real-time data acquisition and storage prototype can meet the real-time data acquisition and storage needs of large-scale wind tunnel sites, effectively reducing the technical risks of developing such real-time database management systems, and laying a good technical foundation for subsequent system development and improvement.
