초록 ▼

An irrigation system having a microprocessor-based controller for providing a desired degree of watering to an area which is divided up into zones, with each zone including a solenoid water valve in series with one or more water dispensing devices, such as spray heads or a drip irrigation tube. Also associated with each of the zones is a moisture sensor which is arranged to be periodically interrogated by the microprocessor-based controller and, when interrogated, provides an electrical signal proportional to the degree of moisture in the soil proximate the sensor. A feature of the invention is that the microprocessor-based controller is extremely easy to program due to the combination of a display screen on which various menus can be presented and a minimum quantity of push-button keys for calling up the menus and for altering sprinkling parameters that are displayed on the menu screens.

대표청구항 ▼

An irrigation system for an area to be watered, the area being divided into a plurality of the discrete zones of possible different soil conditions, each zone including at least one water dispensing device and a solenoid valve having an “on”state and “off”state for controlling the flow of water to said at least one dispensing device for that zone, comprising: (a) a moisture sensor for each of said zones, said moisture sensors penetrating into the soil and producing an electrical signal proportional to the level of moisture in the soil proximate said moisture sensor; (b) a microprocessor-based controller coupled in controlling relationship to said solenoid valves in each of said plurality of zones, said microprocessor-based controller periodically transmitting an inquiry signal to said moisture sensors and said moisture sensors responding by transmitting said electrical signal to said microprocessor-based controller; (c) means in said microprocessor-based controller for selectively actuating said solenoid valves in said plurality of zones to said “on”state at predetermined times during a weekly period unless the moisture sensor for a given zone indicates a predetermined sufficient level of moisture for that zone; and (d) an operator\s panel including an alpha/numeric display and a plurality of push-button keys for facilitating programming of said microprocessor-based controller, certain of said push-button keys operative to present plural menu screens on said display and other of said push-button keys operative to enter new parameter values into said menu screens, said menu screens including at least one of a start-time screen, a time-date screen, a zone screen, a soil sensor screen and a system test screen, said zone screen displaying the selection of a zone number, a water day, a water time and a start time.
