Abstract

An irrigation control system is disclosed. The irrigation control system can include an irrigation controller configured to intercept commands sent from a control unit of an irrigation system to one or more valves of the irrigation system. The irrigation control system can also include a master control valve configured to be disposed on a water supply line upstream of the one or more valves. A communications system comprising one or more processors can be configured to receive data from the master control valve over a communications network, the data related to a flow of water through the water supply line. The communications system can be configured to transmit information to the irrigation controller, the information comprising at least one of: current weather conditions, local water control restrictions, local moisture content, location of the irrigation system, user-defined limits, and flow rate of water through the irrigation system.

Claims

1. An irrigation controller comprising:

an electrical input connection configured to electrically communicate with a control unit of an irrigation system;

an electrical output connection configured to electrically communicate with one or more valves of the irrigation system; and

a control module comprising one or more processors and configured to;

monitor instructions received at the electrical input from the control unit, the instructions comprising commands for opening or closing the one or more valves;

receive data transmitted over a communications network from an external communications system; and

prevent, allow or modify the commands for opening or closing the one or more valve to be transmitted from the electrical output connection to the one or more valves based at least in part on the received data.

2. The irrigation controller of claim 1, wherein the control module is configured to open a switch to prevent the commands from being transmitted to the one or more valves or close the switch to allow the commands to be transmitted to the one or more valves.

3. The irrigation controller of claim 1, wherein the control module is configured to transmit the monitored instructions over the communications network to at least one of a central server and a mobile computing device.

4. The irrigation controller of claim 1, wherein the received data comprises at least one of:

current weather conditions, local water control restrictions, local moisture content, location of irrigation system, user-defined limits, and flow rate of water through the irrigation system.

5. The irrigation controller of claim 1, wherein the external communications system comprises at least one of a mobile computing device, a central server, and a master control valve coupled with a main supply line to the irrigation system.

6. The irrigation controller of claim 1, wherein the control module is configured to transmit the commands for opening or closing the one or more valves to the one or more valves without modifying the commands.

7. The irrigation controller of claim 1, wherein the commands reduce or stop the flow of water through the one or more valves.

8. The irrigation controller of claim 1, wherein the communications network comprises a cellular network, a wireless internet network, or a Bluetooth network.

9. The irrigation controller of claim 1, wherein the control module is configured to record the time and duration that each valve of the one or more valves is open over a pre-determined time period.

10. A master control valve comprising:

a valve body configured to be disposed on a water supply line upstream of one or more valves of an irrigation system, the valve body configured to control a flow of water through the water supply line;

a sensor configured to transduce information regarding the flow of water and to generate a signal based on the transduced information; and

a control module comprising one or more processors and configured to;

receive the signal from the sensor;

process the received signal to determine at least one of an amount of water flowing through the water supply line to the one or more valves and a time period during which water flows through the water supply line to the one or more valves; and

transmit the processed signal over a communications network to an external communications system.

11. The master control valve of claim 10, wherein the control module is configured to receive valve data from an irrigation controller, the valve data including a schedule for each valve of the one or more valves, the schedule comprising at least one of a time at which the corresponding valve is scheduled to run and a duration during which the corresponding valve is scheduled to run.

12. The master control valve of claim 10, wherein the communications network comprises a cellular network, a wireless internet network, or a Bluetooth network.

13. The master control valve of claim 10, wherein the control module is configured to detect whether a particular valve is stuck open and, in response, to send instructions to the valve body to stop the flow of water through the water supply line.

14. An irrigation control system comprising:

an irrigation controller configured to intercept commands sent from a control unit of an irrigation system to one or more valves of the irrigation system, the irrigation controller configured to prevent, allow, or modify the intercepted commands to be transmitted to the one or more valves;

a master control valve configured to be disposed on a water supply line upstream of the one or more valves, the master control valve configured to determine at least one of an amount of water flowing through the water supply line to the one or more valves and a time period during which water flows through the water supply line to the one or more valves; and

a communications system comprising one or more processors and configured to;

receive data from the master control valve over a communications network, the data related to a flow of water through the water supply line; and

transmit information to the irrigation controller, the information comprising at least one of;

current weather conditions, local water control restrictions, local moisture content, location of the irrigation system, user-defined limits, and flow rate of water through the irrigation system.

15. The irrigation control system of claim 14, wherein the communications system comprises one or more central servers.

16. The irrigation control system of claim 14, wherein the communications system comprises a mobile computing device.

17. The irrigation control system of claim 14, wherein the communications system is configured to collect data from the Internet regarding one or more of current weather conditions, local water control restrictions, and local moisture content.

18. The irrigation control system of claim 14, wherein the communications system is configured to receive data from the irrigation controller comprising the time and duration that each valve of the one or more valves is open over a pre-determined time period.

19. An irrigation control system comprising:

an irrigation control unit configured to be programmed by a user to control the operation of an irrigation system;

one or more valves in electrical communication with the irrigation control unit, the one or more valves controlling the flow of water to one or more irrigation lines in response to a control signal sent from the irrigation control unit;

an irrigation controller disposed between and in electrical communication with the irrigation control unit and the one or more valves, the irrigation controller configured to intercept commands sent from the control unit to the one or more valves, the irrigation controller configured to receive data over a communications network from an external communications system and configured to interrupt the control signal based at least in part on the received data.

20. The irrigation control system of claim 19, further comprising a master control valve disposed on a water supply line upstream of the one or more valves, the master control valve configured to determine at least one of an amount of water flowing through the water supply line to the one or more valves and a time period during which water flows through the water supply line to the one or more valves.
