2-Wire Intelligent Irrigation Systems use a single wire pair to create a remotely
The wire pair is separately trenched from the PVC pipe.
I propose to embed the wire pair into the PVC pipe.
Then, each PVC connection will simultaneously connect the water path AND the wire pair to the next segment of PVC.
An intelligent irrigation system
using this invention should cost less, install more quickly and have improved system reliability.
The embedded wire pair will support the electronics of ALL existing 2-wire systems such as Rainbird, Toro, Hunter, and Netafim.
Fig 1 shows a segment of PVC pipe with an extra extrusion on its top that
contains a wire pair. When the PVC pipe is cut,
the extrusion containing the wires is cut back from the edge of the pipe cut. The cut is can be done in the field with a simple tool.
This cut back, or offset, is done to insure that the end face of the
PVC is smooth, and will make a tight fit with the gasket in its
In Fig 1,
a non-conducting End Clip has conductive metal pins that are forced into the strands of the wire pairs
in order to make
These buttons are connected
to wires that pass through the body of the adapter, and which attach to the
conductive buttons in the right side chamber.
These wires connect the corresponding PVC Pipe pins on each end of the adapter, and the electric circuit is thereby continued through the Pipe Coupler.
port on the adapter allows for user connection to the internal wire pair for
diagnostic purposes. The monitor port can also be used for the
connection of surge protectors.
The electrical network can be used to selectively "trickle charge" batteries that are located at the remote locations.
