轮式起重机载荷谱计算软件数据库设计

Database Design of Load Spectrum Calculation Software for Wheeled Cranes

针对轮式起重机载荷谱计算软件开发涉及的数据库设计问题,提出一种基于高级程序设计语言的批量、快速创建数据库方法.首先进行轮式起重机载荷谱数据库的需求分析和详细设计;然后对比不同数据库创建方法,给出具体的数据库创建算法流程;最后采用C++语言开发数据库创建软件,并给出运行实例.所提出的数据库设计方法效率高、节省人力,有利于起重机载荷谱中大批量字段数据表的快速构建.

A method for batch and quick database generation based on a high-level programming language is proposed according to database design issues involved in software development for wheeled crane load spectrum calculations,particularly the vast number of data table types and fields.Firstly,requirement analysis and detailed design of the wheel crane load spectrum database are carried out,and different database creation methods are analyzed and compared.After that,a specific database creation algorithm flow is given.Finally,database creation software is developed in C++language with a running example.The proposed method for database design is efficient and labor-saving,and thus conducive to the rapid construction of data tables for large numbers of fields in crane load spectrum.
