摘　　要：为了提高多层角联织机的自动化与智能化程度,采用基于AC810 PLC主控制器的控制系统,对织机5大运动所需驱动元件采用全伺服驱动器控制。采用EtherCAT以太网总线协议控制上下位机之间与各伺服轴之间的通信,该控制系统具有开放性好、动态响应快、维护方便和布线便捷等优点。根据多层角联织机织造的工艺要求,搭建角联织机硬件系统与软件程序控制系统。针对多品种多层角联织物织造工艺,设计自动化开口控制程序,结合人机界面(HMI)实现开口电子纹板的新建、实时编辑和保存,并对织机工作状态的监控显示与运行参数进行修改。同时针对送经系统特性,准确测量系统张力变化,设计恒张力送经控制算法。最后,对该控制系统进行上机测试,并采集现场实际数据进行分析。结果表明,基于EtherCAT总线通信的全伺服控制能够发挥角联织机高速化、智能化、高质量和高效率的优良性能,可满足不同织造工艺角联织物的生产需求。In order to improve the automation and intelligence level of the multi-layer angle linked loom,a control system based on AC810 PLC main controller is adopted,and the driving components required for the five major movements of the loom are controlled by a fully servo driver.The communication control between the upper and lower computers and each servo axis adopts the EtherCAT Ethernet bus protocol.This control system has the advantages of good openness,fast dynamic response,convenient maintenance,and convenient wiring.According to the weaving process requirements of multi-layer angle linked looms,build the hardware system and software program control system of the angle linked loom.Design an automated opening control program for the weaving process of multiple types and different types of multi layered angled fabrics,and combine it with a human machine interface(HMI)to achieve the creation,real-time editing,and saving of opening electronic pattern boards,as well as monitoring and displaying the working status of the loom and modifying operating parameters.At the same time,based on the characteristics of the let-off system,accurately measure the tension changes that occur in the system,and design a constant tension let-off control algorithm.Finally,the control system is tested on the computer and actual on-site data was collected for analysis.The results indicate that the full servo control based on EtherCAT bus communication can achieve the excellent performance of high-speed,intelligent,high-quality,and high-efficiency corner linked looms,and can meet the production needs of corner linked fabrics in different weaving processes.
