Experimental short circuit and fault identification and protection system and use method thereof

The invention discloses an experimental short circuit and fault identification and protection system and a use method thereof. The system comprises a sampling unit, a signal amplification and filtering unit, a data conversion unit, a controller and a driving unit. The current in an experimental circuit is acquired through an acquisition unit, a current signal is transmitted into a signal amplification and filtering unit and processed, then the processed current signal is transmitted into a data conversion unit, the current signal is converted into a digital signal, and the digital signal is transmitted into a controller; the digital signal is analyzed and calculated according to preset parameters on the touch screen to obtain an output signal, and the output signal is transmitted to the driving unit; in the using process of the system, current in an experiment is identified through preset parameters, and normal current and fault current in the experiment are distinguished; meanwhile, the system adopts multipl
