摘　　要：针对采用电子贾卡与电子横移的经编电子提花控制系统因在运转状态下遭遇意外断电重启后当前编织位置丢失而形成断电疵布的问题,通过采用对主轴的旋转周期进行提花动作角度分区,并依据系统上电后主轴角度位置信息反求断电瞬间提花元件正在执行的贾卡偏置信息与横移垫纱数码、在断点前已完成的贾卡针偏置状态与横移凸轮轨迹起始段数据、在断点后需续织完成的预装载提花信息与横移凸轮轨迹剩余段数据的方法,对提花系统的断电续织反求控制算法进行设计与研究,并经RDJ6/2机型完成电子贾卡与电子横移提花产品断电重启后的顺利续织实验验证。结果表明:现代经编电子提花产品的断电疵布问题可通过提花控制系统的关键控制算法成功解决,本文提出的反求算法设计准确可行。Aiming at the problem of the modern warp knitting electronic jacquard control system using of the formation of power-off defective fabric due to the loss of weave position after restarting,which is caused by unexpected power failure in the operation state,the rotation period of the spindle was subjected to the jacquard motion angle zoning first,and then according to the spindle angle position information after power-on of the system,the jacquard offset information and yarn-laying code executed just at the breakpoint,the jacquard bias state and the traverse cam track completed before the breakpoint,the section data for the preloaded jacquard information and the remaining segment data of the traverse cam track after the breakpoint,were inversed,the inverse control algorithm of the jacquard system was designed and studied,and the algorithm was verified by the RJ6/2 warp knitting machine successfully.The results showed that the problem can be solved successfully by the key control algorithm of the jacquard control system,proving the inverse control algorithm is accurate and feasible.
