基于51单片机的智能火灾报警系统的设计与实现

Design and Implementation of Intelligent Fire Alarm System Based on 51 MCU

电子科技和城市建设的快速发展,电子设备产品使用频率和城市高层、地下以及大型综合性建筑修建的日益增多,在享受便捷生活的同时火灾隐患大大增加,一旦发生火灾,将带来严重危害。为预防火灾的发生,本文设计开发一种新型便捷智能火灾报警系统,由MCS-51单片机、烟雾传感器、温度传感器、LED灯显示模块等组成。当现场环境烟雾浓度和温度达到一定数值时,反馈给火灾报警系统,蜂鸣器发出嘀嘀的响声且警示灯亮起,可实现声光报警、浓度温度显示、报警限值设置等功能。同时,该系统输出联动报警信号,可接至消防联动系统,从而预防或及早发现火灾隐患,减少损失。

With the rapid development of electronic technology and urban construction,the use frequency of electronic equipment products and the construction of high-rise,underground and large-scale comprehensive buildings in the city are increasing day by day.While enjoying the convenient life,the potential fire hazard increases greatly.Once a fire occurs,it will bring serious harm.In order to prevent the occurrence of fire,a new convenient intelligent fire alarm system is designed and developed in this paper,which is composed of MCS-51 single chip microcomputer,smoke sensor,temperature sensor,LED light display module,etc.When the smoke concentration and temperature reach a certain value,it will be fed back to the fire alarm system,the buzzer will sound and the warning light will be on,which can realize the sound light alarm,concentration temperature display,alarm limit setting and other functions.At the same time,the system outputs linkage alarm signal,which can be connected to the fire linkage system,so as to prevent or detect fire hazards as soon as possible and reduce losses.
