摘　　要：造纸术是中国四大发明之一,是促使人类文化传播的伟大发明。在造纸术发明的初期,造纸原料只是树皮和破布。随着时代的发展,人们在生活中对纸张的要求越来越高,对造纸机器的运行速度和系统都有着更高的要求。因此,运用PLC为主控制器,通过变频器加快异步电动机速度,设计速度链和负荷分配方式进行控制,并采用以太网通讯系统,进行人机操作,实现PLC的造纸自动控制系统配置灵活、性能更稳定可靠。Papermaking is one of China’s four great inventions and a great invention that promotes the spread of human culture. In the early days of the invention of papermaking, the raw materials for papermaking were bark and rags. With the development of the times, people have higher and higher requirements for paper in their lives, and higher requirements for the running speed and system of papermaking machines. Therefore, this article uses PLC as the main controller, accelerates the asynchronous motor speed through the frequency converter, designs the speed chain and load distribution method for control. And we use the Ethernet communication system for man-machine operation to realize the PLC papermaking automatic control system configuration flexible, more stable and reliable performance.
