An embedded man-machine interface design of full digital resistance welding machine

The design of man-machine interface was an important part of the full-digital high-current intermediate-frequency inverter resistance welding machine.For the development needs of current domestic welding machine,a visualization graphical man-machine interaction interface system was designed based on WinCE embedded operating system in the paper.The MFC of EVC++4.0 and SQLite database was used to overall development design and unified management of the welding machine data in the interface system,and it also could communicate with the lower machine DSP via RS232 or network.Extensive testing showed that the interface system could achieve user rights management,multiple welding controller management,basic specifications and parameter settings,spot control and real-time monitoring sampling etc.Also,it could be easy to operate and had powerful function and strong real-time.A new method was provided for the man-machine interface design of welding machine with embedded WinCE system.
