Abstract

The present invention relates to an adaptable controller for controlling environmental systems, and more particularly to an improved computer-controlled irrigation and lighting system. Scheduling is selected using a unique graphical user interface and is transmitted to the controller remotely. Sensing devices for water flow to determine leaks and calculate usage using venturi are provided which communicate with the controller to adjust output in real time based on the measurements.

Claims

1. In a water distribution network comprising a water source and at least one watering zone, a programmable water management distribution system comprising:

a) a meter device for measuring water flow interposed between said water source and said water distribution network;

b) at least one valve downstream from said meter device which operates to provide water to said water distribution network; and

c) a programable controller connected to said valve, said controller operating to open and close said valve in accordance with a predetermined schedule and wherein said controller is responsive to flow measurements of said meter device.

2. The programmable water management distribution system according to claim 1, wherein said meter comprises a venturi tube having an inlet section and a constricted throat.

3. The programmable water management distribution system according to claim 2, wherein said meter device further comprises at least one transducer, wherein said transducer is removably affixed to said venturi tube and in physical communication with the water traveling through said venturi tube, said transducer being connected to said controller.

4. The programmable water management distribution system according to claim 3, further comprising a leak detection means which operates to close said valve when the flow measurements of said meter device exceed a preset limit.

5. The programmable water management distribution system according to claim 3, wherein a first transducer is positioned within said constricted throat and a second transducer is positioned within said inlet chamber.

6. The programmable water management distribution system according to claim 1, wherein said controller is remotely programmable.

7. The programmable water management distribution system according to claim 1, further comprising a programming means for remotely programming said controller with said predetermined schedule.

8. The programmable water management distribution system according to claim 1, further comprising a programming means for continually monitoring the water flow to said zones from said flow measurements of said meter device.

9. The programmable water management distribution system according to claim 1, wherein said controller further comprises means for generating a water usage report.

10. The programmable water management distribution system according to claim 1, further comprising at least one zone of electrically operated devices and at least one switch, wherein said zones of electrically operated devices are connected to said programmable controller, such that said programmable controller turns on and off said electrical devices in accordance with a preprogrammed schedule.

11. The programmable water management distribution system according to claim 10, further comprising an electrical metering device, such that said electrical metering device measures electricity usage.

12. The programmable water management distribution system according to claim 1, further comprising a rain sensor connected to said programmable controller, such that when activated said rain sensor disables said at least one valve when rain is detected.

13. A programmable controller for controlling activation of an irrigation system comprising:

memory device for storing scheduling information for said irrigation system, said scheduling information provided by remote programming means;

electrical circuitry for interfacing with and activating at least one irrigation valve for controlling water flow therethrough;

processor unit for signaling said electrical circuitry to activate said irrigation valve based upon said scheduling information; and

sensor device for detecting flow measurements of said irrigation system and providing said flow measurements to said processor unit to allow adjustments to or overriding of said scheduling information based on said measurements.

14. The programmable controller of claim 13 wherein said sensor device comprises a venturi tube.

15. A method of controlling a water management distribution system comprising a programmable remote system connected to a controller of a water distribution network, comprising the following steps:

a) receiving a watering schedule in said remote system;

b) transmitting said watering schedule to said controller;

c) controlling said distribution system in accordance with said schedule; and

d) real-time adjusting of said watering schedule by said controller based on external inputs to said controller.

16. The method of controlling a water management distribution system according to claim 15, further comprising the following steps;

a) storing a daily water usage;

b) calculating an average water usage from said daily water usage;

c) calculating an adjusted water flow rate; and

d) adjusting water flow rate in accordance with said calculations.

17. The method of controlling a water management distribution system according to claim 16, further comprising the following steps;

a) storing at least one flow rate preset limit;

b) comparing said adjusted flow rating to said flow rate preset limit; and

c) shutting down a zone when said adjusted flow rate is outside said flow rate limit.

18. An automatic shut-off system for a water supply line comprising:

a) a valve for opening and closing said water line;

b) control means for controlling said valve;

c) a venturi tube disposed within said water line having sensors for sensing a pressure change in said water line cause by flow in said water line;

d) means for sending a signal from said sensors to said control means indicative of flow;

e) means for comparing said signal with a preset limit;

f) means for selectively closing said valve should said signal exceed said preset limit.
