摘　　要：由于排气污染物检测系统是可移动的,无法进行布线,需要建立无线网络系统来满足设备的需要;文中采用准漫射模型的红外IRDA无线网络,完成在强电磁干扰情况下的高速数据传输,整个传输信号真实准确,未受到噪声和强电磁信号的干扰;通过对准漫射模型的分析,提出增加透镜和最大散射的准漫射模型可以将IRDA的通信距离增加到2.6 m,提高了通信稳定性。the detection system for pollutants emission is mobile, it cannot be completed by the wires, therefore, it must be to establish the wireless network system to meet equipment＇s needs. Based on infrared IRDA wireless network system of quasi--diffuse model, this article completes the high speed data transmission in the strong electromagnetic interference situation, and entires signal transmission accurate, in other words, received signal was not disturbed by the noise and the strong electromagnetism signal. Based on the analysis for quasi--diffuse model, this paper proposes the addition of the lens and the biggest scattering quasi--diffuse model can increase communication distance of IRDA to 2.6m and enhance the stability of the correspondence.
