Abstract


According to the needs of real-time control of the welding process in welding production design the welding parameter detection system based on the DSP . Control core DSP design to achieve real-time detection of the welding process , welding current, arc voltage ; achieve real-time detection and control of the welding speed . This article is designed hardware system the welding parameter detection system . Based on Hall sensor as the sensing element of the welding parameters , design the sample conditioning circuit DSP - based welding parameters and display circuits, able to achieve real-time collection and display of welding parameters . For real-time control of the the future welding current , voltage prerequisite. Welding speed is one of the key parameters that affect the quality of welding in the the welding automatic control system , according to the welding production work requirements , the structural design of welded running gear , the device can achieve precise welding travel speed transmission . The accuracy requirements of the welding process, welding walking mechanism specialized welding walk the hardware driver circuit and software systems design . The hardware used in the three-phase brushless DC motor as welding running gear drive motor . The circuit can achieve the welding start and stop of the walking mechanism , positive and negative phase , the governor , and has over-current , over -voltage, power protection function . A / D unit of the DSP is mainly use software to achieve the processing and conversion of the analog of the welding parameters, etc. , the use of DSP's event management module to achieve a welding the walking mechanism drive signal output , the detection of the welding speed and a welding speed of the PI adjustment. The paper gives a detection result of the detected waveform of the torch position and welding current and voltage . The test results show that the developed welding parameter detection system based on DSP to achieve the design requirements , the control system has good reliability and anti-jamming capability , achieved good control effect .
