摘要
随着超市零售业的快速发展，传统货柜管理存在商品信息查询不便、库存追踪效率低等问题，不仅影响顾客购物体验，也增加了超市运营管理成本。因此，研发一种能高效获取商品信息、实现智能化管理的超市货柜系统具有重要现实意义。
本设计提出了一种基于 STM32F103C8T6 单片机的智能超市货柜系统。系统主要功能包括：通过 RFID-RC522 射频识别模块刷卡，获取当前物品的商品名称、价格及货柜位置等信息；借助 OLED 液晶显示屏实时显示当前读取到的商品详细信息，方便顾客查看与确认；同时，系统通过 ESP8266-12F WiFi 模块将刷卡获取的商品信息传输到手机端，实现商品信息的远程同步与管理。
该智能超市货柜系统的作用在于，为超市运营管理与顾客购物提供了便捷、高效的解决方案。通过快速获取商品信息、实时显示与远程传输数据，既能提升顾客购物时的信息获取效率，改善购物体验，又能帮助超市工作人员更高效地进行货柜管理与库存追踪，降低运营成本，推动超市零售管理向智能化方向发展。

Intelligent Supermarket Container System Based on Single Chip Microcomputer
Abstract
With the rapid development of supermarket retail industry, traditional container management has problems such as inconvenient product information query and low inventory tracking efficiency, which not only affects customer shopping experience but also increases supermarket operation and management costs. Therefore, developing a supermarket container system that can efficiently obtain product information and achieve intelligent management is of great practical significance.
This design proposes an intelligent supermarket container system based on STM32F103C8T6 microcontroller. The main functions of the system include: swiping a card through the RFID-RC522 radio frequency identification module to obtain information such as the product name, price, and container location of the current item; Using OLED LCD display screen to display real-time detailed information of the currently read product, making it convenient for customers to view and confirm; At the same time, the system transmits the product information obtained by swiping the card to the mobile phone through the ESP8266-12F WiFi module, achieving remote synchronization and management of product information.
The function of this intelligent supermarket container system is to provide a convenient and efficient solution for supermarket operation management and customer shopping. By quickly obtaining product information, real-time display, and remote data transmission, it can not only improve the efficiency of information acquisition for customers during shopping, enhance the shopping experience, but also assist supermarket staff in more efficient container management and inventory tracking, reduce operating costs, and promote the development of intelligent retail management in supermarkets.
