Abstract
In time-critical applications a fast transmission of control data between rotating parts of a machine is required for proper system operation. This chapter presents an ultra-fast data transmission using ultra-wideband (UWB) technology for a continuous sub-microsecond communication in rotating systems. A slotted waveguide ring allows a reliable and robust, contactless non-stop data transmission. Control data is encoded in packets of one byte including start and stop bits and transmitted with a data rate of 100 Mbit/s. With high-speed analog-to-digital conversion and digital signal processing less than 150 ns are required for data transmission and reception with possible control data transmission every 80 ns. Circuit design and operating principle of the system are explained and measurement results provided to prove its functionality.
