| 摘 要： | 针对已有检测设备体积大、成本高、要常校准、携带不便的缺陷，设计了便携式甲烷浓度红外探测器。利用甲烷气体在3．3μm波长处对红外光有很大吸收峰这一特性，选用C8051F040单片机对探测器探测的甲烷吸收前后红外光信号进行数据采集、处理和浓度显示，并在超过浓度上限启动声光报警。整个系统体积小、成本低、不需校准、容易操作，能够方便地对甲烷浓度进行检测，是一种实用的设计方案。

| Abstract: | Aimed at limitation of big cubage, high cost, and adjust problems exist in cheek- measure equipment, the paper designs a portable methane＇ s ehroma infrared-detector. Using methane＇ s idiosyncrasy of big infrared-light absorb value where 3.3urn wavelength, the system ehooses C805 IF040 MCU to collect, deal with infrared-light signals detected by light-detector when before and after pass methane, and show methane-chroma. If the methane＇ s ehroma accessed the threshold, the system would started sound and light alarm. The whole system has less cubage, cheaper cost, no-adjust and easily operate, can convenient deteet methane-ehroma, and is a practical design scheme. |
