摘要
随着现代家庭对厨房安全关注度的提升，开发一款高效、智能的厨房安全监测系统显得尤为重要。本文介绍了一款基于STM32F103C8T6单片机的智能厨房安全监测系统，该系统集成了多重安全监测功能，旨在为用户提供全面的厨房安全保障。
本系统通过温度检测模块DS18B20，实时获取厨房内的温度值，确保及时发现并处理潜在的火灾隐患；利用火焰检测模块实时监测厨房内是否有火焰存在，一旦检测到火焰，立即触发报警机制；通过MQ-2烟雾传感器监测厨房内的烟雾浓度，有效预防因烟雾积聚而引发的火灾；用户可通过操作按键，自由设定各项安全参数的阈值范围，以满足不同厨房环境的安全需求；OLED显示屏模块则负责实时展示测量的温度、烟雾数据以及设置的阈值信息，方便用户随时掌握厨房安全状况；当检测到温度超过预设最大值、火焰存在或烟雾浓度超标时，系统将自动启动声光报警，并打开水泵灭火，有效遏制火势蔓延；系统还集成了4G通信模块，可将实时数据传输至手机端，用户通过手机即可远程设置安全阈值、控制水泵开关，并在紧急情况下接收短信提醒。
该智能厨房安全监测系统的作用在于，它能够为用户提供一套全方位、智能化的厨房安全解决方案，有效预防火灾等安全事故的发生，保障用户生命财产安全。

ABSTRACT
With the increasing attention to kitchen safety in modern households, it is particularly important to develop an efficient and intelligent kitchen safety monitoring system. This article introduces an intelligent kitchen safety monitoring system based on STM32F103C8T6 microcontroller. The system integrates multiple safety monitoring functions and aims to provide users with comprehensive kitchen safety protection.
This system uses the temperature detection module DS18B20 to obtain real-time temperature values in the kitchen, ensuring timely detection and handling of potential fire hazards; Real time monitoring of the presence of flames in the kitchen using a flame detection module. Once a flame is detected, an alarm mechanism is immediately triggered; Monitoring the smoke concentration in the kitchen through MQ-2 smoke sensors effectively prevents fires caused by smoke accumulation; Users can freely set the threshold range of various safety parameters by operating the buttons to meet the safety needs of different kitchen environments; The OLED display module is responsible for real-time display of measured temperature, smoke data, and set threshold information, making it convenient for users to keep track of kitchen safety conditions at any time; When the temperature exceeds the preset maximum value, flames exist, or smoke concentration exceeds the standard, the system will automatically activate the sound and light alarm, and turn on the water pump to extinguish the fire, effectively curbing the spread of the fire; The system also integrates a 4G communication module, which can transmit real-time data to the mobile phone. Users can remotely set safety thresholds, control water pump switches, and receive SMS reminders in emergency situations through their mobile phones.
The function of this intelligent kitchen safety monitoring system is to provide users with a comprehensive and intelligent kitchen safety solution, effectively preventing safety accidents such as fires and ensuring the safety of users’ lives and property.
Key words:Smoke alarm; Flame alarm; OLED display; Sound and light alarm; Water pump fire extinguishing
