本论文设计了一款室内人员入侵感知系统，旨在提高室内安全防护水平。该系统使用STM32F103C8T6单片机作为核心控制器，并集成了人体热释电感应模块、步进电机、继电器等组件，实现多种智能化功能。首先，在窗户上放置人体热释电感应模块，并用步进电机代替窗户的开关。系统启动布防时，窗户会自动关闭，当检测到有人接近窗户时，系统将触发声光报警，并通过GSM向房主发送短信提醒“有人闯入，请速速查看”。其次，系统在门外同样放置人体热释电感应模块，并用继电器控制电磁锁。启动布防后，系统会自动上锁，一旦检测到有人靠近门口，系统将启动撒网装置（继电器模拟），触发声光报警，并通过GSM向房主发送短信提醒“有人闯入，请速速查看”。此外，系统还设有一个按键，用于手动控制布防和撤防，同时有一个黄灯指示当前状态。本系统的设计在实际应用中具有较高的可行性和实用性，能够有效提升室内安全保护能力。通过智能感知和迅速响应，可为用户提供安心的居家环境。该项目的研究成果为室内安防技术的发展做出了贡献，具有一定的创新性和推广价值。

This paper presents the design of an indoor personnel intrusion detection system aimed at enhancing indoor security protection. The system employs the STM32F103C8T6 microcontroller as the core controller and integrates components such as the human body pyroelectric infrared sensor module, stepper motor, and relay to achieve various intelligent functionalities.Initially, the human body pyroelectric infrared sensor module is placed near the windows, with the stepper motor serving as a substitute for window switches. When the system is armed, the windows automatically close. If any individual approaches the windows, the system triggers a sound and light alarm and sends a GSM text message to the homeowner, notifying them of the intrusion.Subsequently, a human body pyroelectric infrared sensor module is also installed outside the door, controlled by a relay that operates an electromagnetic lock. Upon arming the system, it automatically locks the door. If someone approaches the entrance, the system activates a simulated net deployment mechanism (relay-based) and initiates a sound and light alarm, sending a GSM text message to the homeowner to alert them about the intrusion.Additionally, the system is equipped with a button for manual arming and disarming, alongside a yellow light indicator to display the current status.The design of this system demonstrates a high level of feasibility and practicality in real-world applications, effectively improving indoor security protection. Its intelligent perception and prompt response capabilities provide users with a secure living environment. The research achievements of this project contribute to the development of indoor security technology and possess certain innovation and promotional value.
