Abstract

This paper introduces the principle and configuration of an auto urine analysis system. The system employs an ARM-LPC2214 as CPU and a color linear-CCD as sensor. A CPLD is used to produce pulses for the CCD and for other circuits in the system. The CPLD is programmed through Verilog HDL language. The sick is determined according to the color change of test strips. Principle of color test circuit and design of software for identifying color data are also described. The software uses the principle of CIE Colorimetry to identify the color. Experiments show that test speed is fast and the result is precise. This system is suitable for the situations in which a large number of samples are to be treated.
