Research on Transmission Line Tower Tilting and Foundation State Monitoring Technology Based on Multi-Sensor Cooperative Detection and Correction

The transmission line tower will be affected by bad weather and artificial subsidence caused by the foundation and other factors in the power transmission. The tower's tilt and severe deformation will cause the building to collapse. Many small changes caused the tower's collapse, but the early staff often could not intuitively notice the changes in the tower's state. In the current tower online monitoring system, terminal equipment often needs to replace batteries frequently due to premature exhaustion of power. According to the need for real-time measurement of power line tower, this research designed a real-time monitoring device monitoring the transmission tower attitude tilting and foundation state based on the inertial sensor, the acceleration of 3 axis inertial sensor and angular velocity raw data to pole average filtering pre-processing, and then through the complementary filtering algorithm for comprehensive calculation of tilt angle, the system meets the demand for inclined online monitoring of power line poles and towers regarding measurement accuracy, with low cost and power consumption. The optimization multi-sensor cooperative detection and correction measured tilt angle result relative accuracy can reach 1.03%, which has specific promotion and application value since the system has the advantages of unattended and efficient calculation.
