A communication tower inclination measurement method based on inertial sensor

Abstract

The invention discloses a method for measuring the inclination angle of a communication tower based on an inertial sensor. By establishing a quantitative analytical relationship between the attitude angle obtained by a traditional inertial sensor based on a gyroscope and an accelerometer and the inclination angle of a communication tower, the output of the inertial sensor is It is directly converted into the inclination output of the communication tower, so as to realize the measurement of the inclination of the communication tower. This method solves the problem that the angle between the communication tower and the vertical line cannot be directly obtained in traditional applications, that is, the analytical relationship between the communication tower's inclination angle, and makes the coordinate transformation relationship between the attitude angle output by the inertial sensor and the communication tower's inclination angle intuitive and clear. Accuracy is controllable. The invention can be applied to all occasions where the inclination angle needs to be measured, such as communication towers, by adopting an inertial sensor, and is a universal conversion method.

Description

technical field [0001] The invention belongs to the technical field of communication iron tower maintenance, in particular to a communication tower inclination measurement method based on an inertial sensor. Background technique [0002] The current communication tower inclination measurement usually uses inclination sensors or inertial sensors, but the user unit is not completely clear about the precise definition of inertial sensor data when using inertial sensors for measurement, especially the roll angle and pitch angle output by inertial sensors. There is a sequence of definitions and there is a coupling relationship, which leads to the user's vague description that the inertial sensor is used to measure the inclination angle, but the conversion result obtained in actual use is not the physical quantity to be measured. [0003] In order to solve the above problems, a communication tower inclination measurement method based on an inertial sensor is proposed. This method ...
