A digital matt-machine interaction system controlled by communications between two processors of TMS320F240 and A/98C2051 was researched in the paper. The system is easy to set and modify welding process parameters by keyboards, and display information of welding site by LCD (Liquid Crystal Display). As one part of multi-task system about TIG welding machine, the coordination of man-machine interaction system with other tasks is the main point to the stability and reliability of its operation. Experiments result indicates that the system is stable, operation-flexible, high precision, and anti-interfering. 相似文献

Digital controlling for GMA welding machine based on DSP 总被引:1,自引:0,他引:1
This paper introduced a welding machine for GMAW using digital controlling method based on DSP (Digital Signal Process ). By means of flexible programming according to welding technologies and experiences the suitable characteristics of welding machine, such as line compensation, welding voltage and current feedback, wire-feed driving, SCR trigging and so on, can be controlled and self-adjnsted using digital signals. Through the designing based on DSP it is put out that the traditional hardware of control circuit is decreased greatly which can enhance the stability and reliability of welding machine. Finally, the welding experiment using CO2 shielding gas proves that the welding process is stable. 相似文献
