Abstract
A distributed control system is provided wherein a master controller inductively delivers power and data to a plurality of remote slave modules or controllers via a plurality of coupling loops formed along a length of transmission line. Each of the remote slave modules, in turn, inductively delivers return data to the master controller via the plurality of coupling loops. The use of inductive coupling provides an advantage over the state of the art because no direct galvanic electrical connection is required between the transmission line and the remote slave modules which promise to simplify installation and enhance long-term reliability. Example applications for the control system described herein include agricultural irrigation systems where individual sprinkler and valve components may be controlled collectively, individually, or in groups or subsets, to vary application rates according to prescribed irrigation parameters.
