摘　　要：设计了基于ARM Cortex-M3内核芯片的数字化管板脉冲焊机。主电路采用全桥IGBT逆变方式,并用霍尔传感器采样输出电流进行反馈,控制系统采用C语言编程、模块化管理,控制PID算法、数字滤波均通过软件编程实现。并采用MCU+CPLD的方式设计管板焊接电源的数字化面板,利用键盘按钮和编码器旋钮组合输入焊接参数,设计简单,操作方便。试验结果表明,采用双MCU+CPLD组合方式来控制管板焊机的参数显示和焊接过程取得了较好的效果。A digital tube-plate pulse welding machine was designed based on ARM Cortex-M3. The main circuit applied IGBT full-bridge inverter circuit. The output current which was detected by Hall current sensor feedback to the control chip. The control system applied digital PID algorithm and precisely controlled the process of welding by compiling program, and adopted the method of MCU + CPLD to design digital panel of the tube-plate welding power, and inputed welding parameters through the combination mode of butter on keyboard and encoder knob. The method of design was simple and convenient operation. The experimental results showed that adopting the combination mode of double MCU + CPLD to control the displaying of parameters and welding processing of tube-plate welding machine had obtained good efficiency.
