Abstract

A method and apparatus for trouble-shooting an irrigation system having a plurality of independently operable irrigation branches and an automatic controller for control of water flow in the branches is disclosed. A radio transmitter and a radio receiver are tuned for the transmission and receipt of two differing signals. The receiver is electrically connected to the controller at a position between the timing apparatus and the rapid station advance motor and at a position enabling direct actuation of water flow. The radio receiver produces output signals actuating the controller in response to the received radio signals. Thus, one radio signal is used to select the branch of the irrigation system through which water is to flow, and the other radio signal is used to trigger flow of water in the selected branch. The radio transmitter is employed from a position remote of the receiver and controller so that the irrigation line can be tested, repaired and re-tested by a single person, who actuates the irrigation system while at a position remote from the controller.

Claims

1. A method for trouble-shooting an irrigation system having a source of water, a plurality of independent irrigation branches, valve means connecting said branches to said source of water, and a completely self-contained controller means having a water supply control portion connected for control of the flow of water to said branches from said source of water and having a branch selection control portion connected to said valve means and formed to enable selection of any one of said branches for the flow of water therein, comprising the steps of:

(a) providing a radio receiver means formed and tuned for receipt of both a water supply signal and a differing station selection signal, said receiver including actuation means formed with a first solenoid switch electrically connected for triggering by said water supply signal to actuate said water supply control portion of said controller means, said actuation means further being formed with a second solenoid switch electrically connected for triggering by said differing station select signal to actuate said branch selection control portion of said controller means;

(b) without modifying the electrical circuitry of said self-contained controller means, electrically connecting a first output connections of said radio receiver means to said water supply control of said controller means for actuation thereof;

(c) without modifying the electrical circuitry of said self-contained controller means, electrically connecting a second output connections of said radio receiver to said branch selection control portion for actuation thereof;

(d) carrying a radio transmitter formed for selective transmission of said water supply signal and said station selection signal to an area remote of said controller means and proximate a suspected source of trouble in said irrigation system;

(e) while proximate the suspected source of trouble, transmitting a station select signal to said receiver means;

(f) while proximate the suspected source of trouble, transmitting a water supply signal to said receiver means;

(g) terminating said water supply signal prior to attempting to repair said irrigation system; and

(h) thereafter transmitting a second water supply signal to said receiver means to enable testing of the repaired irrigation system.

2. The method of trouble-shooting an irrigation system as defined in claim 1 wherein,

said controller means is provided with timing means formed to control the timing of the flow of water through any given one of said branches;

and

said step of electrically connecting said first output connection is accomplished by connecting said first of said output connections to said controller means at a position by-passing said timing means.

3. The method of trouble-shooting an irrigation system as defined in claim 1 wherein,

said valve means and said branch selection control portion include fluid actuated apparatus, and the additional step of:

mounting a solenoid actuated valve to said controller means in fluid connection with said branch selection control portion, and wherein,

said step of electrically connecting said second output connection is accomplished by connecting said second output connection to said solenoid actuated valve.

4. The method as defined in claim 3 wherein,

said solenoid actuated valve is connected to a fluid supply line for said branch selection control portion.

5. The method as defined in claim 3 wherein,

said solenoid actuated valve is connected to a fluid drain line for said branch selection control portion.

6. Apparatus for trouble-shooting an irrigation system having a plurality of independent branches and controller means connected to control the flow and the timing of the flow of water in each of said branches, said apparatus including a radio receiver means formed and tuned for the receipt of two differing radio signals and having actuating means formed for actuation of said controller upon receipt of said radio signals said receiver means being electrically connected to said controller means by conductor means for the actuation of said controller means;

and radio transmitter means formed for selective transmission of two differing radio signals, wherein the improvement in said apparatus is comprised of;

said receiver means being electrically connected to said controller means at an electrical position bypassing the timing function of said controller means, and said receiver means being formed for direct actuation of the branch in which water can flow and for actuation of the commencement of the flow of water; and

said actuating means in said receiver is formed as a first solenoid activated switch electrically connected for triggering by one of said radio signals and a second solenoid activated switch electrically connected for triggering by a remainder of said radio signals.

7. Apparatus for trouble-shooting an irrigation system as defined in claim 6, and

first plug means mounted to said controller means and electrically connected to said conductor means,

second plug means formed to mate with said first plug means and carried by and electrically connected to said receiver for transmission of output signals from said receiver to said controller.
