Device for simulating welding of high-frequency welding machine on production line

Provided is a device for simulating welding of high-frequency welding equipment on a production line. A digital quantity acquisition module receives a host signal sent from the host production line; analog quantity acquisition modules receive a given speed rotary knob signal and a given welding standard adjusting rotary knob signal; the acquisition modules transmit the received signals to a digital signal processing module, and the digital signal processing module converts the received analog data into digital signals and then transmits the digital signals to a digital signal output module; the digital signal output module carries out shaping, error correction and amplification on the digital signals and outputs the digital signals to a digital output module; and a digital-to-analogue conversion module converts the digital signals into analog signals and then transmits the analog signals to the high-frequency welding machine equipment on the production line. Under the condition that the production line does n
