Abstract

The invention belongs to the field of sensor calibration, and in particular relates to an angle displacement sensor automatic calibration system and method. The system comprises an angle displacementcontrol module, N angle displacement sensor excitation input modules, an electrical signal acquisition module and a calibration module, wherein N is a natural number greater than or equal to 1. The angle displacement control module is used to fix a calibrated angle displacement sensor and control the calibrated angle displacement sensor to rotate. The output end of the angle displacement sensor excitation input module is connected with the excitation input end of the calibrated angle displacement sensor. The excitation output end of the calibrated angle displacement sensor is connected with the input end of the electrical signal acquisition module. The angle displacement control module, the angle displacement sensor excitation input module and the electrical signal acquisition module are all connected with the calibration module. The problems of low automatic angle displacement sensor calibration efficiency, easy error and low versatility in the prior art are solved.
