Systems and methods for adaptation to wireless remote control of irrigation valves from existing hardwired control devices
First Claim
1. A wireless adapter system for use with an existing hard-wired irrigation system, the hard-wired irrigation system including sprinkler valves with associated wires and a controller that outputs at least a first set of control signals on the wires so as to activate the sprinkler valves, the adapter system comprising:
- a wireless transmitter that is coupled to one or more control wires of the hard-wired irrigation system such that the wireless transmitter receives the first set of control signals from the sprinkler controller and the wireless transmitter, in response to receiving the first set of control signals, periodically sends a first wireless signal, so as to enable an irrigation solenoid valve; and
a wireless receiver coupled to the an irrigation solenoid valve, wherein the wireless receiver, in response to receiving the first wireless signal, activates the irrigation solenoid valve and wherein the wireless receiver is adapted to de-activate the irrigation solenoid valve if the first periodic wireless signal is not detected during a pre-determined time interval to thereby reduce the likelihood of the irrigation solenoid valve over-watering.

Abstract
A low cost system and method for retrofitting an existing control device to communicate wirelessly with one or more water-flow devices is provided. For example, an existing wired irrigation system may be adapted to allow wireless communication between a commercially available irrigation controller and commercially available water-flow devices, such as sprinkler valves. A wireless irrigation adapter receives control signals from an existing irrigation controller and transmits a wireless representation of the control signals. Water-flow devices may be coupled to one or more wireless receivers that receive the wireless representation of the control signals and operate the water-flow device(s) accordingly. The wireless irrigation receiver(s) listen(s) for the wireless control signals occasionally, thus reducing power consumption by the wireless receiver(s). This system and method may also wirelessly adapt control devices to irrigation that may never have been intended for that purpose when they were fabricated.

6. A method of controlling an irrigation system, the irrigation system comprising an irrigation solenoid valve electrically coupled to a wireless receiver and an irrigation controller electrically coupled to a wireless adapter, the method comprising:
-
transmitting a control signal from the wireless adapter, the control signal being representative of a signal received from the irrigation controller indicating that the irrigation solenoid valve should be activated;
receiving the control signal at the wireless transmitter;
in response to receiving the control signal, activating the irrigation solenoid valve; and
de-activating the irrigation solenoid valve if the control signal is not again received during a predetermined time interval after a prior reception of the control signal, thereby reducing a likelihood of the irrigation solenoid valve over-watering. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14, 15, 16)
