Abstract

The invention relates to an electric power tower instability monitoring method and system based on information fusion. The monitoring method comprises the steps of collecting real-time position data and real-time inclination angle data of an electric power tower in real time; correcting the real-time position data and the real-time inclination angle data to obtain accurate position data and accurate inclination angle data; after the accurate position data and the accurate inclination angle data are encrypted, uploading ciphertext data to a background monitoring client; analyzing the ciphertextdata by the background monitoring client, extracting the accurate position data and the accurate inclination angle data, and calculating inclination data, reverse breaking data, settlement data and horizontal displacement data of the power tower; and according to the inclination data, the reverse breaking data, the settlement data and the horizontal displacement data of the electric power tower,calculating an instability index of the electric power tower, comparing the instability index with a preset threshold value, and when the instability index is greater than the threshold value, sendingearly warning information to related workers by the background monitoring client.

Description

technical field [0001] The invention relates to an information fusion-based power tower instability monitoring method and system, belonging to the technical field of power system data collection and sharing. Background technique [0002] Power transmission and distribution lines are widely distributed and have large spans. The terrain and natural environment along the line are complex. In addition, they are operated in the field for a long time, and are easily affected by typhoons, heavy rainfall, landslides, debris flows and other geological disasters, which bring great harm to the stability of power towers. Instability problems such as tower breakage, tilting and settlement seriously affect the safe operation of the power system. [0003] The current methods for monitoring the instability of power towers mainly include manual inspection, manned / unmanned aerial vehicle inspection, satellite inspection, and online monitoring. Among them, the online monitoring method is real-...
