基于电感耦合的超声监测数据传输设计研究
Research on data transmission design for ultrasonic monitoring based on inductive coupling
摘要
Abstract
To address the difficulty in accurately obtaining electrical parameters of key components for the inductive coupling wireless ultrasonic monitoring systems,the accuracy of existing coil inductance calculation methods and piezoelectric transducer impedance modeling techniques were compared.Taking planar spiral coils as the research objects,the filament method,area integral method,and finite element simulation were used to calculate self-inductance and mutual inductance,with results compared against experimental values.A finite element model of the piezoelectric transducer and workpiece coupling system was established to obtain the impedance spectrum,which was compared with experimental values.The component parameters were incorporated into a three-coil coupling circuit model to construct an monitoring system and conduct thickness inspection verification.The results indicate that the filament method is suitable for self-inductance calculation,with a self-inductance calculation error of less than 3%.The area integral method is appropriate for mutual inductance calculation,with a mutual inductance calculation error of less than 5%within a lift-off distance range of 2 to 10 mm.The finite element simulation accurately predicts the resonant frequency of the piezoelectric transducer.The constructed monitoring system successfully achieveds thickness detection.This study provides methodological references and experimental basis for component selection and parameter design in inductive coupling wireless ultrasonic inspection systems.关键词
