摘　　要：针对目前尿液检测试纸的特点,提出一种基于CCD图像传感器的尿液信息数据采集系统。系统应用CCD图像传感器检测多波长LED照射尿液检测试纸后的反射光强度。采用CPLD芯片EPM7064s产生驱动信号控制CCD芯片TCD1209D,用ARM芯片STM32采集CCD输出的模拟信号。经测试,该数据采集系统可准确采集到尿液试纸反射光的光强变化,输出数据稳定可靠。Considering characteristics of current urine test paper, a urine data acquisition system was proposed based on CCD image sensor. CCD was utilized to measure intensity of light reflected from urine test paper under several LEDs with different wavelength. CPLD chip EPM7064s was adopted to drive CCD module TCDI209D, whose analog output signal was digitalized by ARM chip STM32. The results indicate that this system is able to acquire intensity of reflected light from urine test paper precisely and output reliable data for further analysis.
