摘要
基于气体在中红外波段的选择性吸收原理,分析了甲烷特征吸收谱线,并针对现有煤矿甲烷检测装置存在的不足,提出了基于Z igBee无线通信技术的煤矿甲烷红外检测系统架构.本系统以ARM9 S3C2440微处理器作为硬件开发平台,以嵌入式Linux作为软件开发平台,设计了煤矿甲烷红外检测系统数据采集与传输的硬件及软件开发流程图,实现了检测信号的获取和无线传输.
In view of the shortcomings of the existing methane detection devices for coal mines,based on the principle of the selective absorption of mid-length infrared wave to gases and the analysis of the infrared absorption spectrum of methane,the framework of a methane infrared detection system based on ZigBee wireless communication technology for coal mines is put forward.Based on the hardware platform of the ARM9(S3C2440) and the software platform of the embedded Linux,the software and the hardware for the data acquisition and transmission of the system are designed.The monitoring signal acquisition and wireless transmission are realized.
