摘　　要：针对在线焊接无缝药芯焊丝生产设备中需要多台电机协调转速控制,而且焊丝直径较粗,传统的张力传感器无法使用的特点,应用PROFIBUSDP现场总线实现了PLC与多台变频器高速通讯,通讯方式可以获得变频器的转矩值,利用转矩值作为输入,建立PID调节器,这样系统可以精确控制变频器频率,保证了无缝药芯焊丝生产过程速度协调准确,实现了控制系统的全数字化。Traditional tension sensor can’t be used in the online welding seamless flux-cored wire equipment because of the complex harmonized rotate speed control of many electric motors and main diameter welding wire. To resolve the problem, PROFIBUS DP field bus is applied to achieve high- speed communication between PLC and many inverters. The communication can acquire inverter torque that is input to establish PID adjuster, then system can accurately control inverter frequency and guarantee harmonized speed of seamless flux-cored wire production, so the system carries out total digital control.
