摘要

摘要:提出了一种双通道交替探测透射和散射的气溶胶浓度检测方法,并设计了相应的检测装置。利用光通过气溶胶后被吸收和散射的作用,采用双光路周期性测量90散射光及透射光光强,消除了光源老化及探测器灵敏度不同对测量结果的影响。选用MSP430单片机作为主控芯片,通过对管施加脉冲信号实现对光信号调制,并在探测接收端进行信号的放大及滤波,有效消除了环境因素对测量精度的干扰。采用该测量装置进行了气溶胶测量,结果显示其线性较好,线性相关系数为0.976 5,表明测量系统稳定可靠。

Abstract:An aerosol concentration measurement method based on two channels of transmission and scattering was proposed and a detection device was designed in this paper. The intensities of light scattering at the 90 and transmitting light were measured by two detection ways in periodic, which eliminates the inaccuracy because of light source aging and the difference of detector sensitivity. By choosing MSP430 to be the controller, optical signals were modulated by an exerting pulse signal to LD, and the signals detected were amplified and filtered in the receiver. The system can effectively eliminate environmental interference with the measurement results. The experiment results show that the linear correlation coefficient of the system is 0.976 5 with good linearity, and it is operated stably and reliably.
