随着人类步入信息时代，智能化产品成为信息社会的重要成果之一。在这一背景下，远程报警系统已成为确保高铁、石油化工厂等易燃易爆场所安全管理的关键基础。然而，国内的研究主要集中在综合场所的火灾报警系统上，而适用于家庭的烟雾报警器系统除了要求小巧的结构外，还需要具备经济实惠的特点。本研究基于STM32F103C8T6单片机设计了一款远程烟雾报警系统，具备声光报警、报警状态显示等功能。在硬件设计方面，系统整合了多种传感器，包括DS18B20用于温度检测、MQ-2用于烟雾检测，以及人体热释电传感器用于人体检测。系统通过智能判断传感器数据实现了多重功能。例如，在检测到有人吸烟且有烟雾产生时，系统会通过语音播报警告：“此地禁止吸烟”；当温度超过设定的最大值且检测到烟雾时，系统会进行声光报警。此外，用户可以通过按键设置不同的阈值，并通过OLED显示测量数据。同时，通过WIFI模块，系统还可以将数据远程传送至手机端，实现远程监控和报警功能。经过系统测试，结果表明该系统能够在火灾的早期阶段准确地探测到火情并迅速报警。所设计的烟雾报警器系统具备结构简单、性能稳定、使用方便、价格低廉、智能化、安装便利、维修以及保养成本低等优势，不仅适用于家庭，还适用于各类工作场所和厂房，具有实际的应用价值。通过本研究，为家庭安全管理和火灾预防提供了一种创新的解决方案。

Entering the information era, intelligent products have become essential achievements of the information society. Against this backdrop, remote alarm systems have emerged as critical foundations for ensuring safety management in high-speed trains, petroleum and chemical plants, and other locations prone to fire and explosions. However, domestic research primarily focuses on comprehensive fire alarm systems for larger spaces. For home use, smoke alarm systems need to not only feature compact structures but also be cost-effective. This study designs a remote smoke alarm system based on the STM32F103C8T6 microcontroller, equipped with functions such as audio-visual alarms and status displays.In terms of hardware design, the system integrates various sensors including DS18B20 for temperature detection, MQ-2 for smoke detection, and a passive infrared sensor for human detection. The system intelligently interprets sensor data to enable multiple functions. For example, when both smoking and smoke detection are detected, the system issues an audio warning: “No smoking allowed here.” If the temperature surpasses the defined maximum while smoke is detected, the system initiates audio-visual alarms. Additionally, users can set different thresholds through buttons and view measurement data on an OLED display. Moreover, the system incorporates a WiFi module for remote transmission of data to mobile devices, enabling remote monitoring and alarm functionalities.System testing results indicate that this system accurately detects fires in the early stages and promptly triggers alarms. The designed smoke alarm system boasts advantages such as simplicity in structure, stable performance, user-friendly operation, affordability, intelligence, ease of installation, low maintenance, and operational costs. It is suitable not only for home use but also for various work environments and factories, offering practical utility. This research introduces an innovative solution for household safety management and fire prevention.
