Advanced Sensor-Based Monitoring and Predictive Maintenance System for Electric Power Transmission Towers

This study presents a novel approach for real-time monitoring and settlement estimation of electric power transmission towers by integrating the Beidou satellite system and Real-Time Kinematic (RTK) technique. The proposed system utilizes two base antennas and a rover antenna, leveraging the high-precision positioning capabilities of Beidou and the real-time correction provided by RTK to achieve accurate positioning information. Complementary sensors, including geomagnetic, acceleration, 3-axis directional, and angle sensors, enhance settlement estimation by providing insights into tower orientation, vibrations, spatial orientation, and tilting. Through extensive field testing, the system demonstrates its ability to provide real-time settlement estimation, enabling proactive maintenance and improving the reliability and safety of power transmission infrastructure.
