环锭纺纱信息物理生产系统建模方法

针对环锭纺纱工艺流程长、纤维形态变化大、生产连续性与离散性混合,生产过程中数据流和控制流的关系多样复杂等问题,深入研究了环锭纺纱信息物理生产系统构架。先根据信息物理系统的“计算、通信、控制”特征,定义了环锭纺纱信息物理生产系统;在此基础上分析了环锭纺纱信息物理生产系统的纤维流、数据流和控制流,提出“纤维流-数据流-控制流”融合的环锭纺纱信息物理生产系统模型。然后,基于模型的系统工程方法,采用SysML建模语言建立环锭纺纱信息物理生产系统需求和局部用例模型以及对“纤维流-数据流-控制流”融合建模。研究结果表明,提出的建模方法能有效建立环锭纺纱信息物理生产系统模型,并对环锭纺纱生产智能化具有一定的借鉴意义。

Modeling method of cyber physical production system for ring spinning

In light of the problems such as long process flow of ring spinning,large variations in fiber morphology,mixed production continuity and discreteness,and the diverse and complex relationships between data flow and control flow in the production process,the ring spinning cyber physical production system architecture was comprehensively studied.According to the"computation,communication,and control"characteristics of cyber physical systems,the ring spinning cyber physical production system was defined.On this basis,the fiber flow,data flow and control flow of ring spinning cyber physical production were analyzed,leading to the establishment of a ring spinning cyber-physical production system model encompassing"fiber flow-data flow-control flow".Using the model-based system engineering method,the SysML modeling language was used to specify requirements for the partial models and full model for the ring spinning cyber physical production system considering"fiber flow-data flow-control flow".The results show that the proposed modeling method can effectively establish a ring spinning cyber physical production system model,and has certain reference significance for the intelligent production of ring spinning.
