2.3 BEST PRACTICES FOR TWIG WIRELESS SYSTEM DESIGN:
A GOOD SYSTEM IS MANAGEABLE:
Building good wireless TWIG networks does not happen by accident. They are the result of hard
work by the irrigation dealers, designers and installers, who identify irrigation requirements and
select the best solutions to meet the needs of the farms. Most farms only have a few requirements
for their valve control network. The big one is Manageability: No matter how good the network
design is, the available people must be able to manage and support the network. A network that is
too complex or difcult to maintain cannot function effectively and efciently.
The steps required to design a good network are as follows:
Step 1. Verify the grower goals and technical requirements. Is pump control and Internet access
needed?
Step 2. Determine the functions required to meet the needs identied in Step 1.
Step 3. Perform a TWIG network-readiness and eld survey to understand the topography.
Step 4. Layout a solution showing the valve locations on the site plan.
Step 5. Create a project plan and a bill of materials.
Reliability is essential. Wireless network users generally do not think in terms of the complexity of
the underlying network. They think of the network as a way to access the irrigation controls they
need, when they need them.
FIELD LAYOUT OF ZONE VALVES:
Knowledge of the farming crop and soil is generally the best way to make the eld layout. It is the
ideal to divide the eld into equal size irrigation blocks (these are also called zones). The best effort
is necessary to group the same soil type, crop and watering requirements for each block. All of
this design work is done while staying within the available water supply. The blocks typically each
have a zone valve to control the water ow for the block. In some cases multiple valves are used
in a block for individual laterals. After the eld design is nished and zone valves located, then the
controller location can be determined.
LOCATING THE CONTROLLER:
The controller is the heart of the control system. If possible locate it near the system pump or at
a convenient place. The power supply required for the controller is 110VAC or a 12VDC battery
which requires a charging system be used. The 110VAC is always best if it is available. The TD200
controller cabinet is designed for outdoor use and is rain and water resistant however it is a good
idea to mount the controller in an area out of direct sunlight. Mounting it on the side of a building
or under cover will help it to last longer and reduce temperature and moisture aging. After the
controller location is set then the antenna support and cable needed can be determined.
