Abstract:

In view of the problems that the current widely used DC welding machines by oil production plant may face in the welding process, such as according to the different texture of the metal, changing the size of the welding current, space constraints, manual operation inconvenience under special conditions and other issues, after the research based on the host computer control welding machine remote control. This paper presents a radio frequency remote control device based on low power microprocessor MSP430F149, which consists of the control terminal (Client computer) and the remote control terminal (Host computer) of the welding machine. Hand held remote control device consists of the microprocessor MSP430F149, wireless communication module (nRF905), keyboard circuit, display module, power supply and external circuit components. Welding machine control consists of the microprocessor MSP430F149, DC welding machine, Parameter sensor, wireless communication module, power supply, cable wireless switch and current regulation module. To achieve the remote control of the DC welding machine operating parameters can save the welding time and labor costs, the use of extended welding machine occasions.
