摘　　要：环锭纺纱智能车间的温度对纺纱工艺和成纱质量有很大影响,需要精准控制其波动。提出基于信息物理系统的环锭纺纱智能车间的温度控制方法,通过对环锭纺纱温度大数据的分析,形成对空调出风量、加热量等的调节策略,实现温度闭环精准控制。首先,提出温度闭环精准控制架构,该架构分为物理层、通信层、信息层和控制层4层;其次,建立温度闭环精准控制模型,通过数据分析形成温度精准控制策略;最后通过案例仿真智能车间的气流场和温度场,并对实测平均温度值与模拟温度值作对比。结果表明,所实测平均值和模拟值相比偏差不超过±0.62℃,所提方法可以将智能车间温度精准控制在2℃内波动。The temperature of the intelligent workshop of ring spinning has a great influence on the spinning process and the quality of spinning, and it is necessary to precisely control its fluctuation. The temperature control method of the intelligent workshop of ring spinning based on cyber-physical systems was proposed by analyzing the big data of the ring spinning, forming an adjustment strategy for air conditioning air volume, heating capacity, etc. and the temperature closed-loop precise control was realized. Firstly, the temperature closed-loop precise control architecture was proposed, which is divided into four layers: physical layer, communication layer, information layer and control layer. Secondly, the temperature closed-loop precision control model was established, and the temperature precise control strategy was formed through data analysis. Finally, the airflow field and temperature field of the intelligent workshop were simulated through a case study, and the measured average temperature value was compared with the simulated temperature value. The results show that the deviation between the measured average and the simulated value does not exceed ±0. 62 ℃, and the proposed method can accurately control the intelligent workshop temperature to fluctuate within 2 ℃.
