基于STM32单片机的图书馆座位
管理系统设计与实现
摘 要
针对图书馆座位管理存在的低效与不便，本文设计一款基于STM32F103C8T6单片机的图书馆座位管理系统。该系统主要由光照检测模块、温度检测模块、RFID识别模块、红外避障管、RGB指示灯、OLED显示屏以及WIFI模块构成。通过光照检测模块实时监测室内光照强度，当低于预设最小值时自动开启照明设备；通过温度检测模块监测室内温度，一旦超过预设最大值即启动风扇进行降温。系统支持通过RFID卡进行座位预约与确认，并结合红外避障管模拟座位占用状态，每个座位配备RGB指示灯以直观显示座位状态（未预约-绿灯、预约-蓝灯、已占用-红灯）。用户可通过APP线上预约座位，现场刷卡确认预约，座位状态随之更新。系统通过按键设置各参数阈值，通过OLED显示屏实时展示监测数据，而WIFI模块则将座位信息上传至手机端，便于用户远程查看与管理。该图书馆座位管理系统通过智能化管理，有效提升了座位利用率与管理效率，为读者提供了更加便捷、高效的座位服务。

In response to the inefficiency and inconvenience of library seat management, this article designs a library seat management system based on STM32F103C8T6 microcontroller. The system mainly consists of a light detection module, a temperature detection module, an RFID recognition module, an infrared obstacle avoidance tube, RGB indicator lights, an OLED display screen, and a WIFI module. Real time monitoring of indoor lighting intensity through a lighting detection module, automatically turning on lighting equipment when it is below the preset minimum value; Monitor indoor temperature through a temperature detection module, and start the fan to cool down once it exceeds the preset maximum value. The system supports seat reservation and confirmation through RFID cards, and combines infrared obstacle avoidance tubes to simulate seat occupancy status. Each seat is equipped with RGB indicator lights to visually display seat status (unreserved green light, reserved blue light, occupied red light). Users can book seats online through the app, confirm their reservation by swiping their card on site, and the seat status will be updated accordingly. The system sets the threshold values for various parameters through buttons, displays monitoring data in real time through an OLED display screen, and uploads seat information to the mobile phone through a WIFI module for remote viewing and management by users. The library seat management system has effectively improved seat utilization and management efficiency through intelligent management, providing readers with more convenient and efficient seat services.
