Application of high-precision BDS+GPS deformation monitoring technology in geological hazard monitoring of UHV transmission lines
BDS+GPS deformation monitoring technology is of great significance for high precision monitoring of UHV transmission towers. On the basis of building the BDS+GPS high-precision positioning mathematical model, according to the consistency of the epoch before and after, the paper gives a robust GNSS observation data preprocessing strategy. Considering the high accuracy and fast response of the monitoring algorithm, the real-time sliding window solution strategy is used to monitor the displacement changes of high-voltage transmission towers in real time. BDS+GPS deformation monitoring software is developed with B/C architecture, which supports data acquisition, data analysis, data solution and front-end display. The precision guide rail test proves that the horizontal RMS of the algorithm is less than 3 mm, and the elevation RMS is less than 5 mm, meeting the deformation monitoring requirements of centimeter level and millimeter level.
