摘要
根据纤维自动铺放设备的结构特点和工艺过程,分析了各运动轴之间的运动关系。针对系统轴数较多,且控制要求各不相同的特点,设计了包含数控系统和运动控制器在内的分布式多系统运动控制方案。选用西门子840D sl数控系统实现铺丝系统运动控制,在支撑系统和送丝系统中选择英国Trio公司的Euro 2O9运动控制器作为控制核心。研究了各系统间协同控制问题,给出了工控机同运动控制器及数控系统的通讯方法。样机的试运行表明:各子系统间信息交换顺畅,控制系统整体运行稳定,控制效果良好。
The motion relationships among multiple axes are analyzed based on structural charocteristics and process of the fiber placement equipment. Because of numerous movement axes and different control requirements, the distributed control scheme of multi system includes CNC system and motion controller is designed. The SIMATIC 840D sl CNC system is selected to control fibre placement, and the Trio Euro 209 motion controller is selected as core of both wire feeding system and support system. The problem of cooperative control among multi systems is mainly studied, and the communication methods between industrial computer and motion controller and CNC system are given. The trial run of prototype show that information exchange amon~ multiple systems are in time .and the control system has stable operation and good control effect.
