电子与信息工程学院本 科 毕 业 论 文论文题目 简易电子秤的设计 学生姓名 周 盼 学 号 073521029 专 业 电气工程及其自动化 班 级 073521 指导老师 邓方雄 2025 年 5 月摘 要随着微电子技术的应用，市场上使用的传统称重工具已经满足不了人们的要求，为了改变传统称重工具在使用上存在的问题，在本设计中将智能化、自动化用在了电子秤系统中。此电子秤很大程度上满足了应用需求，具有很大的应用前景。本文以单片机 MCS-51 系列的 AT89C51 集成电路为信息处理核心，提出电子秤的硬件设计方案，详细的分析了各单元的硬件电路，给出了仪器电路设计和软件流程，及相关电路图、原理图，最后介绍了系统的硬件调试和软件调试。关 键 词：电子秤；AT89C51；硬件设计；电路图 ABSTRACTWith the application of micro-electronics technology, traditional weighing tools used in market has been not satisfaction with hunman requirements already. In order to change the traditional weighing tools problems, in this design, I apply intelligent and automation to electronic scales system. This electronic scale is largely to meet the application requirements, and has great application prospects.This article take SCM MCS-51 series AT89C51 integrated circuit as information processing core，Put forward the scheme of hardware design of electronic scales，a detailed analysis of the various units of the hardware circuit, gives the instrument circuit design and software flow, and the related circuit diagram, schematic diagram, finally introduced the system of hardware debugging and software debugging.KEY WORDS: Electronic scale; AT89C51; Hardware design; Circuit diagram目 录1 绪论........................................................................................................................................11.1 选题的背景和意义.........................................................................................................11.2 讨论现状...................................................
