摘　　要：在最短的时间内对有毒气体进行有效检测和及时的预警关系到人们的生命安全。神经性毒气、气体种类和测量痕量浓度不同、分布随机性造成检测与预警的误差,设计一种以ARM-Linux技术为基础的毒气检测平台对有毒有害气体迅速、准确和痕量式测量;对化学传感器阵列多点测量进行分析,根据仪器的测量原理、结构,并设计了图像处理模块和光谱数据分析模块搭建了硬件系统平台;在此基础上利用可见光光谱分析的主成分分析法PCA(principal component analysis)在MATLAB8.0环境下完成了程序的编写和仿真实验;结果表明,该硬件平台能够迅速完成对有毒气体的检测,最短时间可达0.6s,效果比较理想。This article through to the domestic and foreign some testing poisonous and harmful gas hardware system analysis, according to the identification of single component nerve gas, gas type and measuring trace concentration, etc, this paper puts forward a request to ARMLinux technology platform of poisonous and harmful gas quickly, accurately, and trace type measurement. To the chemical sensor ar ray multipoint measurement analysis, according to the measure principle, structure, and design the image processing module and spectral data analysis module built hardware system platform. On the basis of the visible spectrum analysis of principal component analysis PCA, comple ted the program to write and simulation results In MATLAB 8.0. The results show that the hardware platform to quickly complete the toxic gas detection, the shortest time of O. 6 seconds, the effect is ideal.
