Transient signal measuring method, device, system and related equipment

The embodiment of the invention provides a transient signal measurement method, and the method comprises the steps: controlling a signal collection circuit to collect and obtain a first to-be-measured signal in a first preset time period, and carrying out the first signal processing of the first to-be-measured signal through a first signal processing branch, and obtaining a first transient signal; within a second preset time period, controlling the signal acquisition circuit to acquire a second to-be-measured signal, and performing second signal processing on the second to-be-measured signal through a second signal processing branch to obtain a second transient signal; and obtaining a measurement result of the transient signal to be measured based on the first transient signal and the second transient signal. The first signal processing branch is used for processing the first to-be-measured signal collected in the first preset time period, and the second signal processing branch is used for processing the sec
