【摘要】：為了實現(xiàn)對霧霾的快速、高精度在線檢測,提出了一種基于激光散射原理的霧霾檢測光學與電學系統(tǒng)設(shè)計方案.該系統(tǒng)采用紅光激光器作為檢測光源,環(huán)形光電探測器用來接收激光信號.模擬多路復用器選通光電環(huán)輸出的光電流信號,利用IV轉(zhuǎn)換電路與AD轉(zhuǎn)換電路將信號轉(zhuǎn)換為數(shù)字信號,使用串口將信息發(fā)送給屏幕,同時提供上位機數(shù)據(jù)接口實現(xiàn)數(shù)據(jù)傳輸.結(jié)果表明,該光電系統(tǒng)工作穩(wěn)定、速度快,可以較好地滿足激光霧霾檢測儀光電系統(tǒng)的要求.
[Abstract]:In order to realize fast and high precision on-line detection of haze, a design scheme of optical and electrical system for haze detection based on the principle of laser scattering is proposed. The red laser is used as the detection light source and the ring photodetector is used to receive the laser signal. This paper simulates the optoelectronic ring output photocurrent signal of the multiplexer, converts the signal to digital signal by using IV conversion circuit and AD conversion circuit, sends the information to the screen by serial port, and provides the data interface of upper computer to realize data transmission. The results show that the optoelectronic system is stable and fast and can meet the requirements of the photoelectric system of laser haze detector.
