论文题目：基于51单片机的超市密码存储柜控制系统设计与实
现
摘要：随着社会的不断发展，超市已经成为现代人生活的必需品
之一。在超市中，商品的种类繁多，数量庞大，为了更好地管理这些
商品，超市使用了密码存储柜。本篇论文设计并实现了一种基于51单
片机的超市密码存储柜控制系统，通过该系统可以实现对存储柜的管
理和控制。
本论文从系统的硬件组成、软件设计及实现三个方面展开，重点
介绍了51单片机、存储器、键盘和LCD显示屏的功能及使用方法。系
统的软件设计部分主要包括了程序设计、系统架构的设计和用户界面
设计。程序设计方面，主要是通过C语言编写程序，控制存储柜的开
锁、锁定以及用户登录等操作。系统架构设计方面，目的是将程序模
块化，保证系统的有效性和稳定性。用户界面设计方面，主要是通过
LCD显示屏去输出系统的各种提示信息和当前状态。
经过实验验证，本系统可以实现存储柜的开锁、锁定以及用户登
录等操作，同时还具有更高的安全性和可靠性。该系统不仅提高了超
市的管理效率，同时也大大提高了用户的购物体验。

Abstract: With the continuous development of society,
supermarkets have become one of the necessities of modern
people's lives. In the supermarket, there are a variety of
goods and large quantities. In order to better manage these
goods, supermarkets use password storage cabinets. This paper
designs and implements a supermarket password storage cabinet
control system based on the 51 single-chip microcomputer. The
system can realize the management and control of the storage
cabinet.
This paper unfolds from three aspects: hardware
composition of the system, software design and implementation,
and key components including the 51 single-chip microcomputer,
memory, keyboard, and LCD display. In terms of software
design, it includes program design, system architecture
design, and user interface design. In terms of program design,
the program is mainly written in C language to control the
unlocking, locking, and user login operations of the storage
cabinet. In terms of system architecture design, the purpose
is to modularize the program and ensure the validity and
stability of the system. In terms of user interface design,
the LCD display is mainly used to output various prompt
information and the current status of the system.
Through experimental verification, this system can
realize the unlocking, locking, and user login operations of
the storage cabinet, while having higher security and
reliability. This system not only improves the management
efficiency of supermarkets but also greatly improves the
shopping experience of users.
Keywords: 51 single-chip microcomputer, password storage
cabinet, supermarket, control system, C language.
