The invention discloses a power detection device of rotation output equipment. The device comprises a strain bridge circuit, a strain signal acquisition unit, a rotating speed signal acquisition unit and a signal processing unit. The strain bridge circuit is pasted on a surface of a detected shaft and inputs a collected torque signal into the strain signal acquisition unit through a wired mode. The rotating speed signal acquisition unit collects a rotating speed signal of the detected shaft. The signal processing unit receives the rotating speed signal of the rotating speed signal acquisition unit in the wired mode and receives the torque signal of the strain signal acquisition unit and processes the signals. The invention also discloses a power detection method of the rotation output equipment. In the invention, different torque detection means are adopted. Flexibility of the device is high so that the device is suitable for a follow-up device of rotation output. Anti-interference performance of the device i
