摘　　要：针对高频焊管生产测量环境恶劣以及依靠经验观察来控制焊接温度的特点,提出高频焊管温度监控系统.该系统利用抗干扰强、测量精度高的比色测温仪采集焊接温度,通过LabVIEW控制高频电源的输出功率,实现温度调整,通过PID控制实现闭环控制.实验证明,监控系统能够准确检测高频焊管的焊接温度,并有效地提高温度的稳定性.最后提出影响高频焊管温度监控系统的因素.Aimed at the poor measurement and production environment and dependence on empirical observation and control of welding temperature in the production of high-frequency welded pipe,a high-frequency welded pipe temperature monitored control system was proposed.In this system,a colorimetric pyrometer with strong anti-jamming and high measurement precision was used.By using software LabVIEW,the high-frequency power output was controlled to achieve temperature adjustment and closed-loop control.It was verified by test that the system could accurately detect the high-frequency welded pipe temperature,and effectively improve the temperature stability.Finally,the factors that influence the monitore control system of temperature of high-frequency welded pipe were suggested.
