摘　　要：本系统采用单片机ATmega16L控制,由温度传感器DS18B20和气体传感器2M007接收火险信号,通过智能的程序处理,发出声光报警,并以脉冲拨号的形式,将险情通过电话线,拨通预先设置好的电话号码,从而达到多重报警的目的。The system is controlled by microcontroller ATmega16,while the temperature sensor DS18B20 and gas sensors 2M007 receive fire signal.Through the intelligent processing,sound and light alarm is sent out in the form of pulse dialing,thus,danger message is transmitted by the telephone line got through by a pre-set the phone number so as to give a multiple-alarm warning.
