Description

Technical Field

[0002] In the field of intelligent welding control technology, traditional welding machine platforms use a combination of digital screens and knobs as the main method of human-computer interaction. The screen is connected to the main control board of the equipment by wire. Due to the complex on-site environment, the welding gun and the interactive end are often far apart, resulting in inconvenient operation, difficulty in real-time monitoring, and potential safety hazards. In addition, the display driver of the screen is completed by the microcontroller inside the welding machine. Due to the limited resources of the microcontroller, the human-computer interaction interface is relatively simple, unable to display welding parameters in real time, dynamically monitor welding status, and users cannot store welding data in a timely manner. The amount of static database data stored in the microcontroller is also small, and it does not support database updates and expansions. For new welding processes, the welding quality mainly depends on the user's knowledge reserves in welding, and welding is more difficult.

[0003] To this end, the present invention provides an embedded intelligent voice welding system controller device. Summary of the Invention
