摘　　要：设计一种新型的基于CMOS智能视觉的甲烷检测系统,使甲烷的检测变成数字化处理。该系统由三部分组成,包括光路系统获取条纹信息,CMOS摄像采集干涉条纹以及C2000 DSP核心开发板进行数据处理。核心开发板计算出的甲烷浓度值通过串口通信传输到PC端,以曲线方式显示在由Borland C++编写的窗口程序中。同时,当甲烷浓度值超过一定范围时,核心开发板会进行报警提示。This paper design a methane detector of light interference, which is implemented by digital process. This system is made up of three parts, including light path system, CMOS image acquisition system and C2000 DSP core development board. Inter-ference fringe is acquired by light path system and then sampled by image acquisition system. The main program computes in core development board. The methane value attained from C2000 board is sent to Personal Computer through serial communication. It is available to show methane curve in window program, which is written in Borland C++. At the same time, the core development board will alarm when methane value exceeds a certain range.
