摘要
在独居女性生活场景中，居住环境的安全性、异常情况的及时预警及便捷的控制方式，对其生活安全感与生活质量起着关键作用。传统的安全防护多依赖门锁、监控等单一设备，存在异常情况响应滞后、控制方式单一等问题，难以满足独居女性对安全防护的全面需求。
基于 STM32F103C8T6 单片机的独居女性智能安全系统，整合了 MQ-2 烟雾传感器、MQ-135 有害气体传感器、人体热释电 D203S 传感器、OLED 显示屏、按键、语音识别模块 SU-03T、WIFI 模块 ESP8266 及 ULN2003 步进电机驱动模块，实现了对居住环境的实时监测、异常预警与多端控制。系统核心功能包括：通过 MQ-2 监测环境烟雾，烟雾值大于设定最大值时进行声光报警，同时打开窗户和窗帘，并震动弹窗 “烟雾异常”；借助 MQ-135 监测有害气体，有害气体值大于最大值时进行声光报警，控制窗户和窗帘打开，且震动弹窗 “有害气体异常”；利用人体热释电 D203S 监测环境是否有人，布防状态下监测到人时进行声光报警，震动弹窗 “有人闯入”；支持通过语音识别模块 SU-03T 控制窗户、窗帘、照明灯的开关及布防 / 撤销布防；通过按键设置各参数阈值，以及控制窗户、窗帘、照明灯的开关和布防撤防；通过 OLED 显示屏实时展示各项测量数据；通过 WIFI 模块将测量数据发送至手机端，支持在手机端设置阈值、控制窗户、窗帘、照明灯的开关及布防撤防。
该系统的实现，有效提升了独居女性居住环境的安全性与防护的智能化水平，通过多类异常监测、多方式控制及及时预警，为独居女性提供了安全、可靠的居住环境，同时为独居人群的安全防护设备升级提供了参考，具有较高的实用价值与推广意义。

ABSTRACT
In the living scenarios of single women, the safety of the living environment, timely early warning of abnormal situations, and convenient control methods play a crucial role in their sense of living security and quality of life. Traditional security protection mostly relies on single devices such as door locks and monitors, which have problems such as delayed response to abnormal situations and single control methods, making it difficult to meet the comprehensive security needs of single women.
The intelligent security system for single women based on the STM32F103C8T6 microcontroller integrates MQ-2 smoke sensor, MQ-135 harmful gas sensor, human body pyroelectric D203S sensor, OLED display, buttons, voice recognition module SU-03T, WIFI module ESP8266 and ULN2003 stepper motor driver module, realizing real-time monitoring, abnormal early warning and multi-terminal control of the living environment. The core functions of the system include: monitoring ambient smoke through MQ-2, when the smoke value is greater than the set maximum value, an acousto-optic alarm is issued, and at the same time, the windows and curtains are opened, and a vibration pop-up window “abnormal smoke” appears; monitoring harmful gases with MQ-135, when the harmful gas value is greater than the maximum value, an acousto-optic alarm is given, the windows and curtains are controlled to open, and a vibration pop-up window “abnormal harmful gases” is displayed; using the human body pyroelectric D203S to monitor whether there is someone in the environment, when someone is detected in the armed state, an acousto-optic alarm is triggered, and a vibration pop-up window “someone breaks in” is shown; supporting the control of the opening and closing of windows, curtains, lighting, and arming/disarming through the voice recognition module SU-03T; setting various parameter thresholds through buttons, as well as controlling the opening and closing of windows, curtains, lighting, and arming/disarming; displaying various measured data in real-time through the OLED display; sending the measured data to the mobile phone through the WIFI module, supporting setting thresholds on the mobile phone, controlling the opening and closing of windows, curtains, lighting, and arming/disarming.
The implementation of this system has effectively improved the safety of the living environment for single women and the intelligence level of protection. Through multi-type abnormal monitoring, multi-mode control and timely early warning, it provides a safe and reliable living environment for single women, and also provides a reference for the upgrading of safety protection equipment for single people, which has high practical value and promotion significance.
