The invention discloses a VR virtual
welding simulation practical training
system and practical training method, and can solve the technical steps that a traditional
welding training process generatessmog and sparks, and is serious in
pollution, high in training cost and poor in safety. The
system comprises a control cabinet, a VR head-mounted display and a
welding gun, wherein the control cabinet comprises a touch screen and a host; the VR head-mounted display is connected with the host; the welding gun is provided with a
laser position tracer; the
laser position tracer is in communication connection with the host. The
system also comprises a collection module, wherein the welding gun, the collection module and the host are connected in sequence; the collection module comprises a collection circuit and a
single chip microcomputer; the collection circuit comprises a photoelectric coupler OPT300, an eight-bit tristate homodromous output
bus buffer 74HC541D
chip, a
resistor R300, a
resistor R301, a
resistor R302, an indicator light LED300 and a
filter capacitor CA300. The practical training system can accurately measure various kinds of operating information, help students convert welding skills into practical welding work, and can be cyclically used, so that the practical training system saves a lot of human and material costs and is safe and reliable.
