Electronic fence device and detection method for high-voltage cables

Abstract

An electronic fencing device for high-voltage cables and its detection method are disclosed, comprising a camera unit, a communication unit, and a processing unit. The camera unit captures real-time images, including a basic image and a streaming image. The communication unit transmits the real-time images and warning signals. The processing unit is connected to the camera unit and the communication unit. The processing unit receives the real-time images, selects multiple warning boundaries for the high-voltage cable from the basic image based on boundary conditions, concatenates the warning boundaries to form a warning range, configures the warning range in the streaming image, sets a selection range for construction equipment in the streaming image, detects interference between the selected range and the warning range, and drives the communication unit to transmit warning signals.
