Power transmission line abnormal state image snapshot device and method

The invention discloses a power transmission line abnormal state image snapshot device and method. The device comprises a single-chip microcomputer; the camera shooting unit is connected with the single chip microcomputer; the first acquisition unit is used for outputting a first high-level signal to the single chip microcomputer when the optical signal is acquired; the second acquisition unit is used for outputting a second high level signal to the single-chip microcomputer when acquiring a traveling wave current signal; the third acquisition unit is used for outputting a third high-level signal to the single chip microcomputer when the magnetic signal is acquired; the single-chip microcomputer is used for outputting a trigger signal to the camera unit when any high-level signal is received. The camera unit is used for capturing a field picture of the power transmission line when receiving the trigger signal, and the equipment is used for triggering and starting image shooting through a fault signal of the p
