摘 要
在现代生活与公共设施中，自动门系统因便捷性和智能化特点被广泛应用。随着单片机技术与传感器技术的发展，基于嵌入式平台的自动门控制系统以其高效、稳定的优势，成为自动化领域的重要组成部分。
本设计采用 STM32F103C8T6 单片机作为主控芯片，通过超声波传感器实时检测人体与门的距离，当距离小于 1m 时控制门开启，大于 1m 时控制门关闭；检测到的距离数据通过蓝牙模块实时传输至手机端，实现远程监测；通过按键 K1 控制设备启停，按下后启动自动感应模式（人靠近开门、离开关门），再次按下则关闭设备，停止感应控制；显示屏实时显示当前门的状态（开启 / 关闭）和人体到门的距离。
软件部分采用 C 语言进行模块化编程，通过实物测试验证各功能逻辑。经调试与测试，系统能准确响应距离变化并控制门的开关，蓝牙传输稳定，按键操作便捷，显示信息清晰，具备较高的实用价值和应用前景

In modern life and public facilities, automatic door systems are widely used due to their convenience and intelligent features. With the development of single-chip microcomputer technology and sensor technology, automatic door control systems based on embedded platforms have become an important part of the automation field with their advantages of high efficiency and stability.
This design uses the STM32F103C8T6 single-chip microcomputer as the main control chip. It detects the distance between the human body and the door in real-time through an ultrasonic sensor. When the distance is less than 1m, it controls the door to open; when the distance is greater than 1m, it controls the door to close. The detected distance data is transmitted to the mobile phone in real-time through the Bluetooth module to realize remote monitoring. The device is started or stopped by key K1: pressing K1 starts the automatic induction mode (the door opens when a person approaches and closes when they leave), and pressing it again turns off the device, stopping the induction control. The display screen shows the current state of the door (open/closed) and the distance from the person to the door.
The software part adopts C language for modular programming, and the functional logic is verified through physical tests. After debugging and testing, the system can accurately respond to distance changes to control the door’s opening and closing, with stable Bluetooth transmission, convenient key operation, and clear display information, having high practical value and application prospects.
