摘　　要：应用C8051F340单片机技术完成了散射光法便携式浊度仪软硬件的设计。仪器选用波长860 nm的红外发光管和硅光电池作为光电变换元件。同时利用C8051F340完成仪器的光电信号的数据采集、处理、存储、USB2.0数据快速传输以及对电路的控制。通过实验分析,测量结果在误差允许范围内,达到了测量要求。Based on the microcomputer technology of C8051F340, a portable turbidimeter including its hardware and software utilizing scattering light theory was designed. Infrared light emitting diode with wavelength 860 nm was chosen as light source and silicon photocell was chosen as photoactor in the instrument. Data collection, handling, saving of light electricity signal, data delivering by USB2.0 and controlling of electric circuit could be completed by C8051F340. The instrument meets the measure requirements in the extent of measurement error by experimental analysis.
