The invention relates to the technical field of power fault detection, and discloses a direct-buried cable intermediate head fault rapid detection unmanned aerial vehicle system and method, and the system injects a pulse signal into a detected cable, and reaches a preset detection position of an intermediate head of a to-be-detected cable through an unmanned aerial vehicle according to intermediate head positioning information inputted in advance. The sound vibration sensing probe is used for acquiring a sound signal and an electromagnetic signal of a to-be-detected cable intermediate head, the sound signal and the electromagnetic signal are preprocessed by recording triggering time corresponding to the sound signal and the electromagnetic signal respectively, and the preprocessed sound signal and the preprocessed electromagnetic signal are sent to the unmanned aerial vehicle control background. Synchronous time service is performed on the injection time of the pulse signal injected into the detected cable an
