| 摘 要： | 本系统硬件部分采用单片机AT89C52为控制核心，实现报警系统的控制功能。当放置系统的空间内有瓦斯气体泄露（达到一定浓度）时，使气敏传感器受激发，气敏传感器内部发生相应的化学变化而输出电信号，通过A/D转换的数据送入单片机，同时单片机控制蜂鸣器发出声音，发光二极管开始发光，达到声光报警的效果。软件部分应用单片机C语言实现了本设计的全部控制功能。

| Abstract: | The hardware of the system adopts single-chip micro-computer AT89C52 as the control core, to achieve the basic con-trol functions of alarm system. When placing device space of a gas leak （up to a certain concentration）, the gas sensor is excited, the internal gas sensitive sensor will begin corresponding chemi-cal changes and output signal into the microcontroller, through the conversion of A/D data, at the same time, MCU control buzzer sounds, light-emitting diode light-emitting start, to achieve sound and light alarm effect. Application software C language of single chip processor control functions are realized by this design. |
