Optimizing data transmission in communication systems which use magnetic couplings
Journal Title: Mining – Informatics, Automation and Electrical Engineering - Year 2015, Vol 523, Issue 3
Abstract
Communication systems which make use of magnetic couplings are systems in which the transformation of signals is conducted through induction elements. These elements transfer and receive energy from the transportation unit. A good example of such a solution is a shaft communication and signal system which sends a transmission signal through ferromagnetic couplers by means of head ropes or balancing ropes. This type of communication has, undoubtedly, some advantages, such as high reliability and uncomplicated exploitation. Yet, there are some limitations related to the employed bandwidth. The article discusses important issues related to shaft communication and presents methods which allow to make maximum use of available transmission channels.
