description	The embodiment of the invention discloses a power transmission line monitoring method and device based on audio-visual linkage and a medium. Acquiring an abnormal sound signal corresponding to the power transmission line; determining the sound source direction of the abnormal sound based on the preset time difference of the abnormal sound signals received by different microphones; based on the sound source direction of the abnormal sound, adjusting the shooting angle of a preset pan-tilt camera, so as to carry out image shooting on the sound source direction through the pan-tilt camera, and obtaining a hidden danger image of the power transmission line; performing framing and windowing processing on the abnormal sound, and performing sound feature extraction on the processed sound data to obtain audio features of the abnormal sound; and determining hidden danger information corresponding to the power transmission line based on a preset hidden danger identification model, the audio features of the abnormal sou
