Description

technical field [0001] The invention relates to the technical field of shaft detection, and in particular, provides a measuring device and a measuring method for detecting the rotation angle of a shaft. Background technique [0002] In mechanical structures, measuring the angle of a rotating object is a common requirement. The measurement range of the angle is different, sometimes it is necessary to measure the angle less than 360 degrees, and sometimes it is necessary to measure the angle more than 360 degrees. [0003] In many mechanical use scenarios, it is necessary to use the combination of the device and the sensing unit to measure the rotation angle position of the rotating object, especially the rotation angle measurement of more than 360 degrees, which uses the simulated rotation angle sensor to realize the sensing unit and rotation. Contactless setup of the device. [0004] Existing sensing units can be classified into optical sensors, inductive sensors, magnetic...
