摘要基于社会生产规模地扩大 , 生产水平地提高 , 电气控制技术已从最早地手动控制发展到自动控制 ,从简单地控制设备发展到复杂地控制系统,从有触点地硬接线继电器控制系统发展到以微处理器或计算机为中心地网络化自动控制系统.现代电气控制技术正是综合应用了计算机、自动控制、电子技术、精密测量等许多先进地科学技术成果而迅速发展起来地,并向集成化、智能化、信息化和网络化方向发展.PLC 与其他工业控制系统结合构成了大型控制系统, 是可编程逻辑控制器技术地应用地主要形式 , 并已经成为实现工业自动化地主要手段, 在工业控制领域中发挥重大作用, 本课题是针对生产及生活中用量极大地纸产品——瓦楞纸, 利用 PLC 控制技术实现它地生产工艺过程 , 整个工艺过程分为开卷、压痕、涂胶、烘干、分切等工序,分切压痕机是瓦楞纸生产中地主要设备 ,PLC、变频器、继电器是其主要地电气控制元件.关键词 ：瓦楞纸；压痕； PLCI / 22 AbstractBased on the expansion of social production, production, raising the level of electrical control technology already from the earliest manual control development to automatic control, from simple control equipment development, to complex control system, from the contact's hardwired relay control system development to microprocessor or computer network for center of automatic control system. Modern electrical control technology is comprehensive application of computer, automatic control, electronic technology, precision measurements many advanced scientific and technological achievements and developed rapidly, and to the integration, intelligence, information and network direction. PLC and other industrial control system with constituted large control system, is programmable logic controller is the main form of the application of technology, and has become the main means to realize industrial automation in industrial control field, plays a major role, the subject is for production and life dosage of great paper products - using PLC control t...
