摘要
为了防止突发性火灾,智能火灾报警器应运而生。设计采用STC89C52单片机为系统主控,由MQ-2烟雾传感器、DS18B20温度传感器和火焰传感器、声光报警等部分组成。通过设定的阈值检测室内烟雾和温度及火焰并发出声光报警,并用液晶屏来实时数据显示。经测试,该火灾报警器灵敏度高、成本低、响应速率快、安装简单,由于使用的是模块化电路,维护成本也很低,实用性强。
Fire alarms came into being to prevent sudden fire disasters.Our design of a fire alarm aims to detect chemical and physical signals from a variety of fires,and timely inform people to protect personal and property safety.This design uses STC89C52 MCU as the main control system,which is composed of MQ-2 smoke sensor,DS18B20 temperature sensor and flame sensor.It can detect indoor smoke,temperature and flame through the set threshold and send out sound and light alarm,and use 1602 LCD to display real-time data.After testing,the fire alarm has the advantages of high sensitivity,low cost,fast response speed and easy installation.Due to uses of modular circuits,its maintenance cost is low and it′s practically useful.
