Section 4: System Planning
4.1 HOW TO BUILD A WIRELESS VALVE CONTROL SYSTEM:
Understanding the path of the radio signals: All the valve control commands originate at the TD200
controller. The signals between the radios move in both directions for transmit and receive. You
must plan for the signals to reach the valves and be sure to avoid obstructions of soil, water and
vegetation.
Line-of-sight requirement: The radio signals for the TWIG network are line-
of-sight between antennas. This graphic sketch above shows good line-
of-sight between the barn and the repeater antenna. On the other hand, a
line-of-sight intercepts obstructions by the trees. That would obstruct or
diminish radio signals farther out to the valve. In this example a repeater
was needed. One other possible solution is to use a pole and elevate the
TWIG above the tree as shown in the picture on the right.
Valves in a cluster require fewer TWIGs: Irrigation
design for wireless means a different approach to the
overall eld. Designers must carefully plan the water
source, where the pumps will be located and where
the valves are planned. The valve location for eld
blocks may benet by being close together as shown
in this example. The advantage is that one TWIG-4
can be used to control the four valves if each valve
is not more than 50 away. Each valve has an identity
that is unique and can run independently.
