摘　　要：针对大肠杆菌发酵重组类人胶原蛋白控制要求高的特点,设计制造了一种高性能控制系统。该控制系统由基于PC的上位机与基于C8051F340单片机的下位机组成,实现了对发酵参数的实时在线采集、存储和利用神经网络智能算法的准确控制。实验证明:系统运行稳定可靠,故障率低,较人工控制和通用控制器发酵产物湿重分别提高约32.6%和76.7%,且产量稳定波动小,充分满足发酵控制的需求。A high-performance control system for E.coli recombinant human collagen is designed and manufactured to meet the high control requirements.The control system is composed of host PC and lower computer based on C8051F340 MCU.The fermentation parameters can be real-time online collected,stored and precisely controlled by using neural network intelligent algorithm.It is proved that the control system can work stably,reliably and the failure rate is low.Compared with manual control and general-purpose controller,the wet weight of fermentation product is approximately increased by 35 %,76.7 % respectively and fluctuation is small.It can meet the control requirements very well.
