基于FPGA的电涡流传感器静动态校准控制系统设计

Design of Static and Dynamic Calibration Control System for Eddy Current Sensor Based on FPGA

摘要: 电涡流传感器作为一种非接触检测传感器被广泛的应用于工业生产。当使用一段时间后，电涡流传感器可能会因为老化或者其他环境因素的影响，指示值会出现很大的误差甚至错误，所以需要根据电涡流传感器的性能定期地对其进行动态或者静态校准，以保证电涡流传感器的检测精度。目前国内对于电涡流传感器的静态校准和动态校准均是独立研究，且校准自动化程度低。本文运用FPGA软件设计了一套电涡流传感器静动态一体化校准控制系统，有效地实现了电涡流传感器静态校准与动态校准的集成，提高了电涡流传感器校准的效率。

Abstract: Eddy current sensors are widely used in industrial production as non-contact detection sensors. After a period of use, eddy current sensors may experience significant errors or even erroneous readings due to aging or other environmental factors. Therefore, regular dynamic or static calibration is necessary to ensure the detection accuracy of eddy current sensors. Currently, static and dynamic calibration of eddy current sensors in China are conducted independently, and the degree of automation is low. This paper designs an integrated static and dynamic calibration control system for eddy current sensors using FPGA software, effectively integrating static and dynamic calibration and improving the efficiency of eddy current sensor calibration.
