Design of welding power source man-machine interaction system based on Proteus
This paper introduces the features of welding power source man-machine interaction system,which uses two-processor of DSP and MCU to achieve a digital welding power source.An STC89C52 MCU based on man-machine interaction system,which was designed,programmed,simulated and debugged by using Proteus and Keil.The user can set parameter,such as welding current,welding voltage and welding speed,besides also have realtime data display function by man-machine interface.Results verify that the design requirements of two-processor welding power source was met by this designed system,which have features of high-availability,friendly interface and easy operation.This method is provided a basis of the following actual hardware design,which reduces the cycle time and save costs.
