摘要
为了满足不锈钢电加热管产品多样化的需求,提高产品质量,完成了对已投产的不锈钢电加热管小型台式退火炉控制系统升级改造。采用人机交互界面HMI和PLC取代原退火炉的仪表控制系统,实现了不同产品工艺参数的灵活设置、温度数据的采集、归档与显示,设计了模糊PID算法取代传统仪表的常规PID控制算法,使控制系统能根据产品负载的变化,通过模糊理论自动修正PID参数,以保证温度控制的精度。测试结果表明,改造后的系统能自适应管件的变化,产品合格率有效提升。
In order to meet the diversified needs for stainless steel electric heating tube products and improve the quality,the upgrading and transformation of the control system of the small bench type annealing furnace for stainless steel electric heating tube device has been completed.HMI and PLC are used to replace the original instrument control system of annealing furnace,which realizes flexible setting of process parameters of different products,and acquisition,filing and display of temperature data.Fuzzy PID algorithm is designed to replace the conventional PID control algorithm of traditional instruments,so that the control system can automatically modify PID parameters through fuzzy theory according to the changes of product load,which ensures the accuracy of temperature control.The test results show that the improved system can adapt to the changes of tube fittings and effectively improve the qualified rate effectively.
