This technical solution can meet the deployment requirements of different environments, effectively control each unit, use neural network to predict the reliability of satellite signals, and provide basis for selecting timing signals.

[0005] In real life, single Beidou positioning technology has wide application in the field of power transmission lines, such as power transmission line tower deformation monitoring, power transmission line fault positioning and inspection, power transmission line disaster prevention and reduction early warning, and power transmission line construction and maintenance management, etc. For power transmission line tower deformation monitoring, high-precision displacement monitoring sensors are installed at the tower base, combined with Beidou ground enhancement network and high-precision positioning algorithm (such as RTK technology), to monitor the displacement, settlement and other deformation of the tower in real time.

[0079] In the embodiment, the tilt state of the tower is divided into slight tilt and severe tilt, which facilitates the operation and maintenance personnel to take corresponding measures according to different tilt degrees, and improves the operation and maintenance efficiency;

[0080] On the basis of the above, according to the determination result, if the system determines that the preset power transmission line tower is severely tilted, the positioning information of the monitoring point at the time of determination is obtained, and the positioning information is marked as reference positioning information; at the same time, the change of the positioning information is obtained in two natural days as an acquisition period, if the positioning information obtained in the acquisition period is the same as the reference positioning information, the system determines that the preset power transmission line tower is not in the trend of severe tilt; otherwise, it is determined that

[0081] In this embodiment, for the tower determined to be severely tilted, the system further verifies the change of the positioning information to ensure the accuracy and reliability of the judgment;

[0082] At the same time, by obtaining the change of the positioning information in real time, the system can dynamically adjust the judgment of the tower tilt state, avoid misjudgment caused by short-term fluctuations, and enhance the stability of the system.
