发酵过程控制器的研制

本文根据抗菌素生产的特点,利用ATMEL单片机和I2C串行器件,设计了一种带模拟回路的发酵过程控制补料装置。同以往的增强型补料器相比,该装置增加了模拟回路,将需要控制的温度、压力、PH、DO等模拟信号及需要调节的阀门等做到了一台设备上,提高了系统的集成度。通过用VC编制的上位机软件,完全可以代替DCS。

In this paper,according to features of the antibiotic producing process,a supplementing feeder with an analog loop for fermentation process control is designed by using ATMEL single chip micyoco and I2C serial component.Comparing to used enhancement-mode supplementing feeders,an analog loop is added to this device,and the analog signals needing to be controlled for temperature,pressure,PH value and DO,as well as valves needing to be adjusted are added to a single device,thus the integrated level of this system is enhanced.This device can entirely replace DCS by using upper-level-computer software developed by VC.
