NANCE.
Theory of Operation VRI-iS
The Smart Relay Board (SRB) is able to control up to 495 sprinklers individually on a mechanized irrigation
system. Each sprinkler can be pulsed to provide variable rate water application. The ICON module is used as
the user interface to enter and modify the sprinkler map which would identify the percent on for each sprinkler.
The SRB sends messages to the COMM module (ID=00) via RS232, which is then relayed to the other COMM
and valve assemblies. Each sprinkler valve assembly pulses its output based upon the information received
from the SRB.
The SRB controls the entire sprinkler system. It communicates to each sprinkler through a 24VDC-COM module
and many valve assemblies each connected to a sprinkler. A GPS antenna, installed at the end of the pivot
sends $GPGAA messages to the COM module (ID=FB). The COM module puts the message into a buffer. The
SRB then requests this buffer in order to retrieve the GPS $GPGAA message. The SRB then determines the
position of the pivot and based on that position, sprinkler parameters are updated to the valve assemblies based
on the VRI map.
