非接触电容耦合式信号传输方法
Capacitively coupled contactless signal transfer method
摘要
Abstract
In order to solve the wear , signal drift and low reliability problem of the rotational motion mechanism of the contact electrical transmission mechanism such as slip rings , a new non‐contact signal transmission method using the capacitive coupling is introduced . We propose a signal transmission structure , and analyze the distribution parameters and equivalent circuit Modeling and simulation of signal transmission is done and the data transfer circuit is designed . The prototype is built that realizes the real‐time data transparent transmission between the moving parts , and removes the contact and friction . Multi‐channel signal transmission can be performed if it is extended . The measured data transfer rate reaches 400 kbit/ s . This method can be used in aerospace , wind power , medical , military and other fields .关键词
