摘要
设计了一种基于组态王6.55软件的真空低压渗碳上位机监控系统,通过组态王软件与山武仪表DCP31之间的Modbus通讯,利用仪表自带的二自由度(2-DOF) PID功能,实时进行PID修正保证控温的精确度。将渗碳工艺中的变量如C2H2、NH3和N2的流量控制及渗碳扩散时间、脉冲次数、保温时间和淬火方式等一系列参数固化成配方形式,供用户调用和修改。这一软件平台的设计及应用减少了操作人员的误操作和复杂程度,大大提高了低压渗碳的热处理品质。
A monitoring system of vacuum low-pressure carburizing upper computer was designed based on Kingview 6.55 software.Through modbus communication between Kingview software and Yamatake instrument DCP31 and using the 2-DOF PID function of the instrument,real-time PID correction was carried out to ensure the accuracy of temperature control.Variables in carburizing process,such as flow control of C2H2 and NH3 and N2,carburizing diffusion time,pulse number,holding time and quenching mode,were solidified into formulation form for users to call and modify.The design and application of this software platform reduce the mis-operation and complexity of the operators,and greatly improve the heat treatment quality of low pressure carburizing.
