摘要
为了实现对雾霾的快速、高精度在线检测,提出了一种基于激光散射原理的雾霾检测光学与电学系统设计方案.该系统采用红光激光器作为检测光源,环形光电探测器用来接收激光信号.模拟多路复用器选通光电环输出的光电流信号,利用IV转换电路与AD转换电路将信号转换为数字信号,使用串口将信息发送给屏幕,同时提供上位机数据接口实现数据传输.结果表明,该光电系统工作稳定、速度快,可以较好地满足激光雾霾检测仪光电系统的要求.
In order to realize the rapid and precise on-line detection of haze,a design scheme of optical and electrical system for haze detection based on the laser scattering principle was proposed. In the proposed system,a red laser was adopted as the detection light source,and an annular photoelectric detector was used to receive the laser signal. In addition,the analog multiplexer was adopted to select the photocurrent signal exported by the photoelectric ring,and the IV and AD conversion circuits were applied to convert the photocurrent signal into the digital signal. The information was sent to the screen with the serial port,and the data interface of upper computer was provided to realize the data transmission. The results showthat the photoelectric system can stably work, has fast speed, and can better meet the requirements in the photoelectric system of laser haze detection system.
