摘　　要：多功能火灾报警器采用ATC89C52单片机为核心控制器,利用烟雾传感器MQ-2检测烟雾浓度、通过ADC0832模数转换器对检测到的数据处理,使用温度传感器DS18B20检测温度,通过液晶LCD1602显示当前的烟雾值和温度值,通过按键设定相应的阀值。当环境中可燃气体浓度或温度等发生变化时,单片机控制相应的报警电路,并驱动负载工作。经过软硬件设计、调试与测试,系统能在紧急状态下发出报警,并驱动相应的灭火装置,自动灭火,达到设计的目的。Multifunctional fire alarm uses ATC89C52 MCU as the core controller, takes advantages of smoke sensor MQ-2 detecting smoke concentration, processes the detected data through the ADC0832 converter, uses the temperature sensor DSI8B20 detecting temperature,displays the current smoke and temperature values through the LCD LCD1602,and sets the corresponding threshold through the button. When the concentration of combustible gas in the environment or the temperature has changed, the MCU controls the corresponding alarm circuit and drives the loading. After the design, debugging and testing of hardware and software, the system can alarm in an emergent condition, and drive the corresponding fire extinguishing device, the automatic fire fighting, to achieve the design purpose.
