摘　　要：为了减少人们日常的生活中住宅火灾事故的发生,有必要设计一款适合于大多数居民楼的智能火灾报警系统。本设计采取软硬件相结合的方法,硬件选用了烟雾传感器(MQ-2)和温度传感器(DS18B20)作为数据采集模块,选用单片机AT89S52为核心的控制单元模块,以LED灯和蜂鸣器为报警模块,用LCD把采集的数据和阈值显示出来,及其它相关电子元器件,构成了报警器的硬件系统。软件采用C语言编程,将传感器的参数用LCD显示出来,当烟雾浓度及温度超出设置的阈值时,通过单片机控制LED发光及蜂鸣器报警,以达到火警及智能提醒功能。实验结果表明,该系统满足居民楼火灾报警的需要,且报警器结构简单,易于控制,成本低,实用性高。In order to reduce the occurrence of residential fire accidents in people’s daily life, it is necessary to design an intelligent fire alarm system suitable for most residential buildings. This design adopts the method of combining software and hardware. The hardware selects the smoke sensor(MQ-2) and temperature sensor(DS18B20) as the data acquisition module, and the single chip microcomputer AT89S52 as the core control unit module, the hardware system of the alarm is composed of LED(Light Emitting Diode) light and buzzer as the alarm module, LCD(Liquid Crystal Display) to display the collected data and threshold, and other related electronic components. The software adopts C language programming to display the parameters of the sensor with LCD. When the smoke concentration and temperature exceed the set threshold, the LED light and buzzer alarm are controlled by the single chip microcomputer to achieve the function of fire alarm and intelligent reminder. The experimental results show that the system basically meets the needs of residential building fire alarm, and the alarm has the advantages of simple structure, easy control, low cost and high practicability.
