%X 本文以STC89C52单片机系统为控制处理平台，气敏传感器对气体浓度进行自动采样，转换芯片将采样信息进行模数信号转换，并反馈给单片机判断，当实时采样浓度低于报警值时，绿灯亮红灯熄灭；当浓度超过报警值，绿灯熄灭红灯亮，单片机控制负载电路，控制电磁阀关闭气体通道以及打开电扇设备，蜂鸣器报警；同时GSM装置向用户手机发送报警短信。通过编程和Proteus仿真实验，设计一款成本低，准确性较高的燃气安全报警器。
In this paper, the STC89C52 single-chip microcomputer system as a control and processing platform, gas-sensitive sensors for automatic sampling of gas concentration, the conversion chip will be sampling information for analog-to-digital signal conversion, and feedback to the single-chip microcomputer to determine when the real-time sampling concentration is lower than the alarm value, the green light is on the red light is off; when the concentration is more than the alarm value, the green light is off the red light is on, the MCU to control the load circuit to control the solenoid valve closes the gas channel as well as open the fan device, buzzer alarm; at the same time the GSM device to the user’s cell phone to send an alarm SMS. Through programming and Proteus simulation experiments, design a low-cost, high accuracy gas safety alarm.
