基于C++和SQL的流速标准装置检定软件设计

Design of the Verification Software for Flow Velocity Standard Device Based on C++ and SQL

摘要:

研制了一种基于环形水槽的流速标准装置,并运用面向对象的程序设计方法和多层架构模型完成了标准装置检定软件的设计。软件具体的功能模块由C++程序设计语言实现,检定数据管理由SQL Server数据库实现,其中着重对数据库的设计方法和检定参数设置、检定流程监控、数据处理和结果生成等功能模块的实现方法进行了研究。测试结果表明,检定软件既能够实现期望的功能性需求,又具备实用性、可靠性、扩展性等非功能性需求,从而有效提高了流速标准装置的自动化程度。

Abstract:

A flow velocity standard device based on annular flume was developed. And the design of the standard device verification software was completed by using the object-oriented programming method and the multi-layer architecture model. The specific function module of the software was realized by the C ++ programming language, and the verification data management was realized by the SQL Server database. In addition, the design method of database and the realization method of several function modules, such as verification parameter setting, verification process monitoring, data processing and result generation, were studied emphatically. The test results show that the verification software can not only meet the expected functional requirements, and have non-functional requirements such as practicability, reliability and scalability. Therefore, the automation of flow velocity standard device is effectively improved.
