摘　　要：β-甘露聚糖酶发酵过程控制系统布线复杂、影响参数多、自动化程度低,因此设计一套基于CAN现场总线的发酵过程控制系统。CAN测控节点、工业控制计算机通过CAN总线,与各智能仪表间可直接通信,形成开放性网络,简化系统结构,提高控制效果。另外,采用基于QDPSO算法的BP网络控制发酵液的pH值,其精度比常规提高50%。Countering the problems existing in the control system of β-mannanase ferment process, such as complex wires deployed, many parameters influenced, low automation, a fieldbus control system about ferment process based on CAN BUS is designed. Via fieldbus, CAN measure ＆ control node, IPC and the intelligent devices can communicate with each other directly, like an open network. The system structure is more concise and the control effect is improved in this system. Further, by using a QDPSO-BP network to control pH of the ferment liquid, the control accuracy increases by 50% in comparison with the accuracy via normal control method.
