摘要
目前尿液分析仪普遍采用反射光强法来测量尿液中各成分的浓度值。介绍一种便携式尿液分析仪设计方案,利用颜色与浓度之间对应关系,通过测量试剂块颜色,得到浓度值。简要介绍尿液分析仪的测量原理及颜色识别部分的软硬件设计。
At the present time urine analyzer usually uses ＂reflectance light- intensity＂ to measure concentration of different ingredients in urine. In this paper a scheme of the portable urine analysis instrument is introduced using measure the color of urine test strip to get the concentration by corresponding relationship between color and concentration. Basic measure principle of instrument and hardware circuit and software of color recognition part is given in this article.
