基于 STM32 单片机的家庭智能火灾安全系统研究 Research on family intelligent fire safety system based on STM32 single chip microcomputer 内容摘要近些年来，社会的飞速发展，电子科学技术和计算机软硬件技术的进步，所以我们的生活水平跟着提高。大厦林立、房屋建设也越来越复杂，大量的用电器以及复杂交错的线路使我们的日常生活存在着安全隐患，那么火灾安全问题也成了我们生活中一大需要解决的问题，所随之而来越来越多的火灾系统和灭火系统也应运而生。本设计基于单片机设计了小型智能家用火灾报警系统，可实现烟雾报警、温度异常报警以及红外检测和外部中断等功能。在硬件选择方面，采用了以 STM32F103C8T6 单片机为主控芯片，集成了温度传感器（LM75A）、烟雾气敏传感器（MQ-2）、微型人体感应传感器 PIR、有源蜂鸣器以及 6×6×6 轻触开关等，编写程序通过各个模块的传感器对环境种的温度、烟雾浓度数据信息的实时采集，再由单片机进行数据存储与处理，随后根据设计逻辑控制各模块元件做出相应的应对措施，排除隐患，尽可能避免意外发生。关键词：STM32 单片机 传感器 智能 火灾报警系统 AbstractIn recent years, our standard of living has improved, given the rapid development of society, the development of electronic technology and computer hardware and software technology. The building is more and more complex, a large number of electrical appliances and complex staggered lines make our daily life have potential safety hazards, so the fire safety problem has become a big problem in our life to be solved, and more and more fire systems and fire extinguishing systems have emerged. A small fire alarm system of intelligent home based on single chip microcomputer is designed, which realizes the functions of smoke alarm, temperature abnormal alarm, infrared detection and external interruption.In terms of hardware selection, stm32f103c8t6 single chip is used as the main control chip, which integrates temperature sensor (LM75A), smoke gas sensor (mq-2), micro human body sensor PIR...
