1. A method for detecting system failure, comprising:
obtaining, when a system to be detected is powered on or off, a real-time voltage oscillation signal acquired by a voltage sensor arranged in a detection circuit of the system, wherein the detection circuit is a circuit where a source and drain of a switching device of the system are located;
determining a degradation trend of the system according to the real-time voltage oscillation signal and a reference voltage oscillation signal corresponding to the detection circuit of the system; and
performing a failure detection on the system according to the degradation trend of the system.
