摘要
在差别化超细复合纤维生产线中,物料的工艺配比和连续输送是保障产品质量的基础。提出了以S7-1200可编程控制器为核心,以矢量变频器、气动元件等为控制系统执行机构,以触摸屏作为现场监控和操作设备的自动控制系统设计方案。介绍了系统的软、硬件设计思路、程序流程及人机界面。方案采用485通信和以太网通信双网络通信模式,降低了系统成本。该控制系统已经在企业中投入使用,结果表明,系统运行稳定、可靠。
In the differential superfine fiber production line, the process ratio and continuous transportation of materials are the basis for guaranteeing the product quality. An automatic control system design scheme is proposed. In this scheme, the S7-1200 programmablecontroller is put forward as the CPU. The vector frequency converter, pneumatic components, etc. constitute the actuator of control system,and the touch screen is used for on-site monitoring and operation. The software, hardware design idea, program flow and man-machineinterface are introduced in detail. The scheme adopts 485 communication and Ethernet communication to reduce the system cost. The system is already in use in the enterprise. The results show that the system is stable and reliable.
