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 400kbit/s. This method can be used in aerospace, wind power, medical, military and other fields.

Key words: conductive slip ring, capacitive coupled, contactless, signal transmission
