Wind power tower footing deformation monitoring system and monitoring method based on Beidou III attitude measurement
The invention discloses a wind power tower footing deformation monitoring system and method based on Beidou III attitude measurement, and the method comprises the steps: 1, arranging a Beidou III satellite antenna at each of four corners of a wind power tower footing, taking one antenna as a reference, and forming three base lines with the other three antennas; feeder lines of the four antennas are connected to a north hopper III attitude measuring device. 2, the Beidou III attitude measurement device obtains data such as carrier phases, Beidou satellite elevation angles and Beidou satellite azimuth angles of the four paths of Beidou signals, and sends the data to a remote network server; 3, resolving a carrier phase double-difference observation equation of the three base lines on the remote network server by adopting an improved Kepler optimization algorithm to obtain attitude angles of the three base lines; and 4, calculating respective elevation differences according to the pitch angles and the length of the three base lines so as to analyze the differential settlement condition of the wind power tower footing. The method has the characteristics of high measurement precision, intelligence and low cost, and has a wide application prospect.
