Electric shock prevention early warning method and device

The invention discloses an electric shock prevention early warning method and device. The electric shock prevention early warning method is used for carrying out electric shock prevention early warning on high-altitude operation personnel on an electric pole, multiple levels of detection points are arranged on the electric pole, and the vertical distances between the different levels of detection points and the ground are different. Acquiring a first linear distance between the first-stage detection point and the operator; wherein the first-stage detection point is the detection point closest to the ground in vertical distance; when the first linear distance meets a first preset rule, triggering a matching function to determine whether the operator is matched with the first-level detection point; if yes, an authorization signal is sent to the first-stage detection point; and if not, sending an alarm signal to the first-stage detection point. According to the invention, an operator is prevented from carrying o
