High-Voltage Overhead Line Threading Board and Its Pulley State Monitoring System

In the current overhead line threading process, the status monitoring of the threading board and the pulley are generally performed by arranging construction personnel on the towers of the line section to observe. Usually, when an abnormal state occurs during the threading process, the construction personnel then contact the ground personnel and the pay-off operator on the side of the tensioner. This process will delay a lot of time, and failure to notify in time will cause even greater accidents, which will seriously affect construction efficiency. Based on the current construction status of overhead lines, this paper proposes a set of video pose monitoring systems for intelligent pulleys and threading boards. The system can obtain the video data of the pulley and the posture information of the threading board, and then transmit these data to the ground workstation in a point-to-point manner. The practice has proved that the system has high real-time performance, reliability, clear video images, long transmission distance, and easy installation. It can meet the on-site construction conditions and greatly improve on-site construction efficiency while ensuring the safety of on-site construction.
