Design of control system for hollow spindle novelty twister based on PCI bus

根据花式纱线的成纱原理,将花式纱的工艺参数和机器调整参数整合到上位机的设计软件中,由上位机数据库导入。花型工艺参数向机械传动系统的传递使用双口RAM实现工控机的PCI总线与单片机的双向并行通讯。工作中上位机负责对下位机发送指令和接收来自下位机对传动系统中各个回转部件的监控数据,下位机负责对传动系统的监控,驱动花式纱生产设备中的各个回转部件实时变速,从而加工不同的花式纱,实现对空心锭花式捻线机的控制。

According to fancy yarn＇s producing mechanism, this paper provides a new design of control system for hollow spindle novelty twister. The fancy yarn process parameters and machine adjusting parameters ＇are integrated in the software design and introduced into the database. In this way, based on dual-RAM and PCI bus, all the parameters are transmitted to machine driving system to realize the parallel communications between IPC and MCU. IPC is responsible for sending and receiving data, while MCU is responsible for monitoring machine driving system, which regulates rotors of the twister and execute real-time changing speed. Thus it produces various kinds of fancy yarn and realizes the control of hollow spindle novelty twister.
