摘　　要：气体检测系统的建立主要依据气体浓度与电压关系,进行浓度与电压之间转换,实现浓度显示,发光二极管、蜂鸣器报警。系统主要采用C51单片机作为控制模块,实现对气体浓度信息的采集、处理、转换、判断。当检测到的值低于设定报警阀值时,LED仅显示测得的气体浓度,当气体浓度过高,则由单片机向报警系统发出指令,报警灯闪烁,蜂鸣器开始报警并对此系统进行仿真,为气体检测系统从理论到实践的应用提供依据。The establishment of the gas detection system is mainly based on the relationship between the concentration of the gas and the voltage. The system converts concentration and voltage data,achieves concentration value display and light-emitting diodes and buzzer alarm. This system mainly uses the C51 single chip microcomputer as the control module,realizes the collection,the processing,the transformation,the judgment to the gas density information. When the detected value is lower than the set alarm threshold,LED display only shows the measured gas concentration,and when the gas concentration is too high,SCM will sends out the control command to the alarm system. The warning lights will flash,the buzzer will start to alarm and the system will simulate. In the aspect of gas detection system,it provides the basis from theory to practical application.
