Recently, continuous heavy rainfall weather has occurred in many places in China, which has brought great challenges to transmission line operation and maintenance. Under heavy rainfall weather, water droplets attached to the conductor will change the resonance characteristics of the conductor and affect the vibration response of the conductor. At the same time, the increase in precipitation exacerbates soil erosion, and disasters such as landslides, landslides, and mudslides may occur around the foundation of transmission lines, leading to settlement, tilting, and collapse of the towers.
In response to this phenomenon, Dingsin Wisdom has developed Beidou transmission line tower settlement online monitoring device, which is used to monitor transmission line The device is used to monitor the tilt, settlement and slope displacement of transmission lines to improve the prevention and control of geologic hazards on transmission lines.
Principle of online monitoring device for tower settlement of transmission line
The device adopts BeiDou high-precision positioning technology, combined with BeiDou ground-based augmentation station, to carry out 24-hour on-line monitoring of the tilt, settlement, displacement and deformation of the power tower. The monitoring data is wirelessly transmitted back to the backstage monitoring center system, and according to the original real-time data flow of each monitoring point and base station, using the BeiDou data processing engine, it carries out the baseline solving between the base station and the positioning point, so that it can obtain the high-precision real-time three-dimensional coordinates of the towers, and set up a traceable deformation monitoring database of the geologic disaster body, so as to realize the comprehensive and intelligent monitoring and early warning response.
