摘　　要：研制基于激光散透比理论能快速准确检测牛乳大分子含量的实验装置。该装置利用散射光与透射光的比值表征大分子成分的含量,借助蠕动泵实现牛乳样本自动输入与输出,运用ICL7650来设计微弱信号的检测,放大电路实现散透比的测量,并以实时操作系统μC/OS-II为核心设计整个系统的软件部分。实验数据证明,该装置能够实现对牛乳大分子的快速实时测量。An experimental device was developed for rapidly and accurately detecting macromolecular components in milk.It used the ratio of scattered light and transmitted light to characterize the macromolecular content of milk.The authors used the peristaltic pump to realize the automatic input and output of the milk samples,and used ICL7650 chip to design the weak signal detection amplifier circuit for detecting the ratio of scatter-transmitted light.Real-time operating system μC / OS-II is the core design of the software part of the whole system.The experimental data prove that the device can achieve a fast real-time measurement of milk macromolecules.
