Abstract

The invention provides a one-dimensional inclination noncontact measurement method and a one-dimensional inclination noncontact measurement system. A plurality of noncontact displacement sensors with absolute distance measurement functions are adopted, a measuring plate arranged on a to-be-measured target is measured, and finally, a one-dimensional inclination measurement result can be acquired directly through data processing of displacement values of the displacement sensors. The displacement sensors are arranged on the same straight line, and the straight line and the rotation center line of the to-be-measured target are orthogonal. Wide-range inclination measurement is achieved by sectional measurement and automatic switching technologies. A double-sensor gradient algorithm, a multi-sensor mean value method and a weighted average method can be adopted for data processing. By the one-dimensional inclination noncontact measurement method, the defect that inclination sensors are directly mounted on the to-be-measured target can be overcome, and the measurement result is independent of the eccentric distance between the measuring plate and the rotation axis of the to-be-measured target.

Description

technical field [0001] The present invention relates to a method and system in the technical field of geometric quantity measurement, in particular to a method and system for one-dimensional inclination non-contact measurement based on absolute distance measurement. Background technique [0002] The inclination refers to the angle between a plane and the datum plane (general value horizontal plane). Instruments that measure inclination are called inclinometers or levels. Inclination is one of the common measurement items in the field of geometric quantities. At present, in many fields of the national economy, there are various demands for inclination measurement. Conventional inclination measurement methods mainly use a magnetoresistive sensor to measure the orientation of the body relative to the earth's magnetic field to achieve inclination measurement. The advantage of this method is that it is easy to operate, easy to use, and can measure one-dimensional or two-dimens...
