Method for measuring inclination angle of communication iron tower based on inertial sensor

Abstract

The invention discloses a method for measuring the inclination angle of a communication iron tower based on an inertial sensor. The output of the inertial sensor is directly converted into the outputof the inclination angle of the communication iron tower by establishing the quantitative analysis relation between the traditional attitude angle obtained based on the inertial sensor consisting of agyroscope and an accelerometer and the inclination angle of the communication iron tower, so that measurement on the inclination angle of the communication iron tower is realized. By the method, theproblem in the traditional application that the included angle between the communication iron tower and a vertical line, namely the communication iron tower inclination angle analysis relation, cannotbe obtained directly is solved, so that the coordinate conversion relation between the attitude angle output based on the inertial sensor and the inclination angle of the communication iron tower isstraightforward and the precision is controllable. The method can be applied to all the occasions which need to measure the inclination angle of the communication iron tower by the inertial sensor andis 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 ...

[0004] Based on this, it is necessary to solve the problem that the traditional technology ignores the coupling of the pitch angle and the roll angle, combined with the use conditions of the communication tower, to provide a communication tower inclination measurement method based on the inertial sensor, which can overcome the traditional method and directly take the output of the inertial sensor. to use, while ignoring its essential physical definition and coupling relationship, which will lead to the shortcomings of measurement errors, so that this method has the characteristics of clear physical concept and accurate measurement information, and can be used to measure the inclination angle of communication towers and similar installation conditions and pole towers
