Research and Design of Arc Welding Parameters Control and Environment Monitoring System Based on DSP

Abstract

In the process of the welding operation, a large number of welding smoke, toxic gas, and other pollutants will be produced, which can cause a variety of respiratory diseases. Therefore, the welder’s health is affected and the atmospheric environment is polluted. To monitor the detrimental soot substances produced in the arc welding process, an arc welding parameters control and environmental monitoring system was built by taking high-performance DSP (Digital Signal Processor) TMS320F2812 as the control core, which uses wireless communication technology. Multi-information sensing and welding parameters control can be carried out through the system in the arc welding process. The concentration of welding smoke, harmful gas, and other substances in the arc welding environment can be monitored in real time and the real-time environmental conditions are displayed visually. The functions of audible and visual alarms, automatic ventilation, and telecommunication are provided by the system. A lot of experimental verification and debugging results show that parameters control in the arc welding process and the monitor welding environment in real time could be realized by the built system and is running well.
