摘要
水的浊度是反映水质优劣的一个十分重要的指标,为了检测液体中的浮游物的含量,系统采用了被测液体与标准样本液体参考比对的双光路结构,设计了一种直射式光电浊度测量装置,硬件电路包括信号检测处理模块,信号处理模块,单片机AT89S51数据处理模块及液晶LCD1602显示模块。系统经标定后调试,测量结果稳定,线性误差小于±1%。
The turbidity of water is an important index to reflect the quality of water, in order to detect the content of the floating things in the liquid, the system uses the double optical path structure on the basis of the measured liquid refer- enced and compared with the standard sample liquid, and it designs a direct-injection photoelectric turbidity measurement system, whose hardware circuit includes signal processing module, signal processing microcontroller AT89S51 module, data processing module and liquid crystal display module LCD1602. the system is debugged after standardized with stable measurment results, whose linear error is less than ±1%.
