- PAGE I - 汽车衡称重系统的软件设计 摘 要 随着计算机技术在工业方面越来越深入而广泛的应用，汽车衡称重系统的实施在技术上已逐步成熟。汽车衡称重系统是一个不断发展的新型学科，利用现代计算机和大型数据库技术，实现汽车衡称重系统，能够进一步加强企业管理，有效堵塞各种管理漏洞，大大提高工作效率。 本文选用Visual Basic 6.0作为前台开发工具，SQL Server 2000作为后台数据库开发的汽车衡称重系统的软件设计的详细过程。汽车衡称重系统被广泛应用于矿山、饲料厂和石油化工等企业，通过分析汽车衡称重系统的称重过程、数据需求、操作步骤和软件实现的主要功能，提出了利用计算机控制的汽车衡称重系统的开发方案，并完成了应用程序设计及相关文档的建立。文中介绍了汽车衡称重系统程序设计的系统分析，包括可行性分析、业务流程分析等，系统设计部分主要介绍了系统功能设计、数据库设计及代码设计，系统实现部分说明了几个主要模块的功能。所设计的系统具有待称重车辆基本数据录入、称重数据采集与动态显示、称重数据处理等基本功能。为了对应用程序进行测试，设计了一个智能仪表模拟程序，该仪表程序通过串行接口成功地与所设计的应用程序进行了数据通信。应用程序操作简便，功能齐全，实现了预期的设计目标。 关键词：汽车衡称重系统；串行通信；智能仪表 Abstract With more and more widespreading and profound application of computer technology in the industry, the implementation of truck scale weighing system has become sophisticated in technology step by step. Truck scale weighing system is a new subject with development. By modern computer and large-scale database technology, realizating truck scale weighing system should be organized efficiently and organically, which means tightening up the enterprise management and strengthening effective management of enterprise. The experimental of this thesis takes Visual Basic 6.0 as developing language, and SQL Server 2000 as backstage database of the truck scale weighing system of detail process of application software. The truck scale is extensively applied in large scale machine of mineral mountain, feedstuff factory, and petrochemical enterprise etc., weighing together with truck to measure. Through analyzing main function of that system weighing process, data need, operation steps and software implementation, this thesis put forward the development project of truck scale weighing system with computer, and has completed the establishment of applied program design and relative document. In the thesis, it introduced truck scale weighing system analysis of the system program design, including feasibility analysis, business flow process analysis etc.; The system design part mainly introduced the design of system fu
