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.

Description

technical field [0001] The invention belongs to the field of sensor calibration, and in particular relates to an automatic calibration system and method for an angular displacement sensor. Background technique [0002] With the continuous improvement of measurement automation level, the application of sensors is becoming more and more common. Various sensors are used in scientific research and business work, and angular displacement sensors are one of them. In order to ensure the reliability and accuracy of the performance parameters of the angular displacement sensor. It is very necessary to measure and calibrate the angular displacement sensor regularly. [0003] At present, the calibration of angular displacement sensors generally uses existing equipment such as turntables, FLUKE5080 multi-function calibration sources and digital multimeters for calibration. During the calibration process, the following problems exist: [0004] Full manual operation, that is, the inpu...
