摘要
数字化焊接电源控制系统的发展经历了从单个MCU控制到双MCU控制,再到DSP+MCU双核控制,尤其是数字信号处理器DSP在电源中的广泛应用,使得焊机控制精度更高、输出更具柔性化、系统稳定性更好,使焊接电源的整体性能不断提升。设计的脉冲MIG焊机数字控制系统就采用DSP(TMS320F2812)和MCU(STC89C58RD+)双核控制,可实现脉冲和非脉冲MIG焊,并且脉冲焊时具有一元化调节功能。
The development of control system for digital power source has gone through a transition from single MCU control system to double MCU control system and to DSP+MCU dual-core control system.Especially,wide application of DSP in welding power makes control precision higher,outputing more flexible and system stability higher and therefore makes whole performance constantly improved.In this paper,digital unified pulsed welding machine is designed to use DSP(TMS320F2812)+MCU(STC89C58RD+)dualcore control system as digital control system,realizing pulse and non-pulse MIG welding and unified regulating function in pulse MIG welding.
