摘要
本论文旨在设计一个基于单片机的火灾检测系统。该系统采用STC89C52单片机作为核心控制器，并结合MQ-7传感器和火焰传感器，实现对一氧化碳浓度和明火的监测与报警。在功能方面，系统首先利用MQ-7传感器检测环境中的一氧化碳（CO）浓度。当CO浓度超过预设的最大值时，系统会触发声光报警器进行报警，并通过GSM模块发送短信给相关人员，内容为：“一氧化碳浓度过高，请速速查看”。这一功能可以及时提醒人们注意一氧化碳的危害，并采取必要的防范措施。其次，系统还利用火焰传感器检测是否存在明火。当检测到明火时，系统会触发声光报警器进行报警，并自动开启水泵进行灭火。同时，系统也会通过GSM模块发送短信给相关人员，内容为：“发生明火，请速速查看”。这一功能可以迅速发现并应对火灾情况，减少火灾的危害程度。通过以上功能的设计与实现，本论文所提出的火灾检测系统能够有效监测环境中的一氧化碳浓度和明火情况，并在检测到异常时及时进行声光报警、发送短信通知和自动启动灭火装置等措施，提高了火灾检测和应对的效率和准确性。该系统具有较高的实用价值，可广泛应用于各种场所，为人们的生命财产安全提供有力的保障。。

Abstract
The aim of this paper is to design a fire detection system based on a microcontroller. The system utilizes the STC89C52 microcontroller as the core controller and incorporates the MQ-7 sensor and flame sensor to monitor and alert for carbon monoxide (CO) concentration and open flames. In terms of functionality, the system first uses the MQ-7 sensor to detect the concentration of carbon monoxide in the environment. When the CO concentration exceeds the predefined maximum value, the system triggers a sound and light alarm and sends a GSM message to relevant personnel with the content “High carbon monoxide concentration detected, please take immediate action.” This function serves to promptly alert individuals about the dangers of carbon monoxide and encourages them to take necessary precautions.Additionally, the system uses a flame sensor to detect the presence of open flames. When an open flame is detected, the system triggers a sound and light alarm, activates a water pump for fire suppression, and sends a GSM message to relevant personnel with the content “Fire detected, please take immediate action.” This function enables the system to swiftly identify and respond to fire incidents, thereby reducing the extent of fire hazards.By implementing the aforementioned features, the proposed fire detection system effectively monitors carbon monoxide concentration and open flames in the environment. It promptly responds to anomalies by triggering sound and light alarms, sending SMS notifications, and automatically initiating fire suppression mechanisms. This enhances the efficiency and accuracy of fire detection and response. The system demonstrates significant practical value and can be widely deployed in various settings, providing robust protection for life and property.
