Abstract

The invention is used for either testing the output angel appointed by the angle sensor or testing each calculation equivalence value of the angle sensor, and automatically giving out the report about the testing data.

Description

technical field [0001] The invention relates to a detection device and method of a high-precision and low-cost angle sensor, which belongs to the field of optical-mechanical-electrical integration. Background technique [0002] The angle sensor is a high-precision sensor, and a high-precision measuring device is required to verify its accuracy. In the prior art, only a wide range of angle detection can be performed on the angle sensor, that is, a certain angle is rotated each time, such as 120 degrees, and a higher-precision encoder is used to check its accuracy. Such a system can only measure local angles, and cannot automatically detect the accuracy of each angle or each equivalent in a short time, and the cost of a higher-precision angle sensor used for detection is expensive. Contents of the invention [0003] The purpose of the present invention is to avoid using a higher precision angle sensor to detect the accuracy of the high precision angle sensor. At the same t...
