摘要

为了解决金霉素发酵罐发酵液黏度大、组分复杂、含有渣质难于在线自动检测的难题，根据折光率测量原理，采用STM32系列32位微控制器STM32F103RCT6作为主控制器，CCD作为测量传感器，实现了总糖含量在线自动测量系统。分析了光线在不同介质中传播时发生的折射反射现象，给出了总糖含量测量的离线测量原理。该系统从发酵罐自动取出发酵液，经过滤得到被测料液，根据CCD传感器的数据计算被测料液的折光率，由此得出料液的总糖浓度值。实验结果表明，基于折光法研制的金霉素发酵罐总糖含量在线自动检测系统的测量精度为0.1Brix。该系统在实验过程中运行稳定，能满足企业的实际生产需求。

Abstract

It is hard to automatically determine total sugar content due to high viscosity

complex composition and impurities of chlortetracycline fermentation solution

therefore an online automatic measuring system for total sugar content based on refraction method was developed by using an STM32F103R microcomputer as the main controller and a CCD as the imaging sensor. The principles of refraction and reflection occur in the light propagation in different medium were analyzed and applied to measure the total sugar content in chlortetracycline fermentation tank. In the measurement

fermented liquid automatically taken out from the chlortetracycline fermentation tank was filter at first. Then the refractivity of the solution was calculated with the data of CCD

thus the total sugar content of fermented liquid was evaluated. The experimental result demonstrates that the system developed in this paper with the measuring precision of 0.1 Brix runs stably in the process of experiment

and can meet the requirements of production in real field.
