BACKGROUND
With the increased desire for water conservation while maintaining healthy yard and crops, it has become important to use the advances in technology and communication systems to provide efficient use of water resources. Many irrigation systems and irrigation hardware are crude or unduly complicated resulting in the existing systems being used at non-optimal levels.
What is needed are methods, systems, and computer program implemented products for regulating irrigation in areas that are predictable and often over watered because caretakers and/or older irrigations systems are not responsive enough to effectively conserve water while maintaining aesthetically pleasing or healthy landscapes. The disclosure addresses the above needs by providing methods, systems, and computer program implemented products for regulating the use of water over a computer network by generating irrigation protocols and sending those protocols over the computer network.

DETAILED DESCRIPTION
The disclosure extends to apparatuses, methods, systems, and computer program products for optimizing water usage in growing plants for yard and crops. The disclosure also extends to apparatuses, methods, systems, and computer program implemented products for regulating the use of water over a computer network by generating irrigation protocols and sending those protocols over the computer network. The disclosure discloses embodiments and implementation of improved control units optimizing water use and additional environmental conditions. In the following description of the disclosure, reference is made to the accompanying drawings, which form a part hereof, and in which is shown by way of illustration specific implementations in which the disclosure may be practiced. It is to be understood that other implementations may be utilized and structural changes may be made without departing from the scope of the disclosure.
It will be appreciated that the disclosure also extends to methods, systems, and computer program products for smart watering utilizing up-to-date weather data, interpreting that weather data, and using that interpreted weather data to send irrigation protocols with computer implemented instructions to a controller. The controller may be electronically and directly connected to a plumbing system that may have at least one electronically actuated control valve for controlling the flow of water through the plumbing system, where the controller may be configured for sending actuation signals to the at least one control valve thereby controlling water flow through the plumbing system in an efficient and elegant manner to effectively conserve water while maintaining aesthetically pleasing or healthy landscapes.
As used herein, the terms environment and environmental is used to denote influence-able areas and conditions that can be adjusted by operable components of a system. For example, a landscape environment can be optimally irrigated or lit with operable components of corresponding systems such as sprinkler systems and lighting systems.
FIG. 1 illustrates and embodiment of an irrigation controller, also referred to sometimes as a control unit, that may be used within a system for executing irrigation protocols by causing operable irrigation components to actuate in accordance to the irrigation protocol. As can be seen in the figure, a control unit 10 may comprise a housing 12 and a user input 20. In an implementation the user input may have a generally circular or annular form factor that is easily manipulated by a user to input data and to provide responses to queries. As will be discussed in more detail below, the user input may provide/receive a plurality of input movements, such as for example, rotation, speed of rotation, push and click, click duration, double click, and the like. The control unit 10 may further comprise an electronic visual display 14, either digital or analog, for visually outputting information to a user. As illustrated in the figure, an embodiment may comprise a stackable configuration wherein the control unit 12 is configured to be stacked on to the irrigation adaptor 13 such that the control unit electronic connector of the control unit mates with a corresponding electronic connector of the irrigation adaptor
Additionally, it should be noted that an embodiment may comprise a plurality of visual outputs, and other components of the control unit 10, such as the user input 20 may be configured to output visual information. Analog visual outputs may be provided by components such as bulbs and the like. Digital visual outputs may be provided by components such as, liquid crystal displays, light emitting diodes, electro-luminescent devices, to name a few. In an embodiment, the control unit 10 may further comprise an electronic audible device 16, either digital or analog, for audibly outputting information to a user. Additionally, it should be noted that an embodiment may comprise a plurality of audible outputs, and other components of the control unit 10 may be configured to output audible information. Analog audible outputs may be provided by components such as speakers, mechanical clicks, etc. Digital audible outputs may be provided by components such as, piezo-electric circuits and speakers. It should also be appreciated that the housing 12 may be configured to be substantially weather resistant such that it can be installed and used outdoors. It will be appreciated that the controller 10 may be electronically and directly connected to a plumbing system, such as an irrigation sprinkler system, that may have at least one electronically actuated control valve for controlling the flow of water through the plumbing system. Additionally, the controller 10 may be configured for sending actuation signals to the at least one control valve thereby controlling water flow through the plumbing system in an efficient and elegant manner to effectively conserve water while maintaining aesthetically pleasing or healthy landscapes. It should be understood that in an implementation, the controller 10 may further comprise memory for recording irrigation iteration data for a plurality of iterations after a plurality of irrigation protocols have been executed. In an implementation, the controller 10 of a system and method may further record irrigation iteration data into memory in case communication with an irrigation server is interrupted.
FIG. 2 illustrates an overhead view of a landscaped yard surrounding a house. As can be seen in the figure, the yard has been divided into a plurality of zones. For example, the figure is illustrated as having ten zones, but it will be appreciated that any number of zones may be implemented by the disclosure. It will be appreciated that the number of zones may be determined based on a number of factors, including soil type, plant type, slope type, area to be irrigated, etc. which will help determine the duration that needed for each zone. It will be appreciated that the controller and its zonal capacity may determine the number of zones that may be irrigated. For example, a controller may have a capacity of eight, meaning that the controller can optimize eight zones (i.e., Zone 1-Zone 8). However, it will be appreciated that any zonal capacity may be utilized by the disclosure.
In an implementation, each zone may have different watering needs. Each zone may be associated with a certain control valve 115 that allows water into the plumbing that services each area, which corresponds to each zone. As can be seen in the figure, a zone may be a lawn area, a garden area, a tree area, a flower bed area, a shrub area, another plant type area, or any combination of the above. It will be appreciated that zones may be designated using various factors. In an implementation, zones may be designated by the amount of shade an area gets. In an implementation, zones may be defined according to soil type, amount of slope present, plant or crop type and the like. In some implementations, one or more zones may comprise drip systems, or one or more sprinkler systems, thereby providing alternative methods of delivering water to a zone.
It will be appreciated, as illustrated in FIG. 2, that a landscape may have a complex mix of zones or zone types, with each zone having separate watering needs. Many current watering systems employ a controller 110 for controlling the timing of the opening and closing of the valves within the plumbing system, such that each zone may be watered separately. These controllers 110 or control systems usually run on low voltage platforms and control solenoid type valves that are either completely open or completely closed by the actuation from a control signal. Often control systems may have a timing device to aid in the water intervals and watering times. Controllers have remained relatively simple, but as disclosed herein below in more detail, more sophisticated controllers or systems will provide optimization of the amount of water used through networked connectivity and user interaction as initiated by the system.
FIG. 3 illustrates a schematic diagram of an optimized irrigation control system 200 that communicates over network in order to benefit from user entered and crowd sourced irrigation related data stored and accessed from a database 226. As illustrated in the figure, a system 200 for providing automated irrigation may comprise a plumbing system, such as a sprinkler system (all elements are not shown specifically, but the system is conceptualized in landscape 200), having at least one electronically actuated control valve 215. The system 200 may also comprise a controller 210 that may be electronically connected to or in electronic communication with the control valve 215. The controller 210 may have a display 211 or control panel and an input 255 for providing information to and receiving information from the user. The controller 210 may comprise a display or a user interface 211 for allowing a user to enter commands that control the operation of the plumbing system. The system 200 may also comprise a network interface 212 that may be in electronic communication with the controller 210. The network interface 212 may provide network 222 access to the controller 210. The system 200 may further comprise an irrigation protocol server 225 providing a web based user interface 231 on a display or computer 230. The system 200 may comprise a database 226 that may comprise data such as weather data, location data, user data, operational historical data, and other data that may be used in optimizing an irrigation protocol from an irrigation protocol generator 228.
The system 200 may further comprise a rule/protocol generator 228 using data from a plurality of databases for generating an irrigation protocol, wherein the generation of an irrigation protocol is initiated in part in response to at least an input by a user. It should be noted that the network 222 mentioned above could be a cloud-computing network, and/or the Internet, and/or part of a closed/private network without departing from the scope of the disclosure.
In an implementation, access may be granted to third party service providers through worker terminals 234 that may connect to the system through the network 222. The service providers may be granted pro-status on the system and may be shown more options through a user interface because of their knowledge and experience, for example, in landscaping, plumbing, and/or other experience. In an implementation, worker terminals may be a portable computing device such as portable computer, tablet, smart phone, PDA, and/or the like.
An additional feature of the system 200 may be to provide notices or notifications to users of changes that impact their irrigation protocol. For example, an implementation may provide notice to a home owner/user that its professional lawn service has made changes through a worker terminal 234. An implementation may provide a user the ability to ratify changes made by others or to reject any changes.
In an implementation, an irrigation system 200 may comprise a plurality of control valves 215, wherein each control valve corresponds to a zone of irrigation.
In an implementation, user communication may be facilitated through a mobile application on a mobile device configured for communicating with the irrigation protocol server 225. One or more notifications may be provided as push notifications to provide real time responsiveness from the users to the system 200.
The system 200 may further comprise an interval timer for controlling the timing of when the notifications are sent to users or customers, such that users/customers are contacted at useful intervals. For example, the system 200 may initiate contact with a user after predetermined interval of time has passed for the modifications to the irrigation protocol to take effect in the landscape, for example in plants, shrubs, grass, trees and other landscape.
In an implementation, the notifications may ask the user to provide information or indicia regarding such things as: soil type of a zone, crop type of a zone, irrigation start time, time intervals during which irrigation is occurring, the condition of each zone, or other types of information or objective indicia.
Illustrated in FIG. 4 is an exemplary crop (grass) root zone showing roots in various soil types. Referring to FIG. 4, it will be appreciated that the optimization of the irrigation and plumbing system is to provide the requisite water needed to maintain a healthy landscape and no more. Thus, the general understanding is that the amount of water that is lost during evapotranspiration per zone must be replenished at each irrigation start and run time. It will be appreciated that evapotranspiration is the amount of water lost from the sum of transpiration and evaporation. The U.S. Geological Survey defines evapotranspiration as water lost to the atmosphere from the ground surface, evaporation from the capillary fringe of the groundwater table, and the transpiration of groundwater by plants whose roots tap the capillary fringe of the groundwater table. Evapotranspiration may be defined as loss of water from the soil both by evaporation from the soil surface and by transpiration from the leaves of the plants growing on it. It will be appreciated and understood that factors that affect the rate of evapotranspiration include the amount of solar radiation, atmospheric vapor pressure, temperature, wind, and soil moisture. Evapotranspiration accounts for most of the water lost from the soil during the growth of a plant or crop. Accurately estimating evapotranspiration rates is an advantageous factor in not only planning irrigation schemes, but also in formulating irrigation protocols to be executed by a controller to efficiently use water resources.
Illustrated in FIG. 4 is an example of grass 410 and its root zone 420. Also illustrated is an example of the various soil types that may be present per zone, such as clay 432, silt 434, or sand 436, etc. It will be appreciated that the landscape may be considered healthy and water use and conservation may be considered optimal, when the irrigation and plumbing system function or operate to replenish the water in the root zone 420 when water is present at about 50% in the root zone 420. Thus, when water is present in the root zone 420 in an amount greater than about 50% then the duration of the watering for that zone is shortened. Conversely, when water is present in the root zone 420 in an amount less than about 50% then the duration of the watering for that zone is increased. The objective is to replenish the soil with water in the root zone 420 to 100% and no more to optimize and conserve the amount the water used to maintain a healthy landscape. It will be appreciated that any amount of water over 100% saturation in the root zone 420 leads to water runoff that is not efficiently used. Thus, it will be appreciated that the ability to accurately determine the amount of water present in the soil may be advantageous for optimizing irrigation in an irrigation system.
FIG. 5 illustrates a front view of a controller having an annular user input having an opening that extends through the entire width of the controller (or control unit portion). As can be seen in the figure, a control unit 510 may comprise a housing 512 and a user input 520. In an implementation of the user input 520 may have a generally circular or annular form factor that is easily manipulated by a user to input data and to provide responses to queries. During use the user input 520 may revolve around an axis such that a user may rotate the dial to quickly enter large data ranges of values by simply spinning the dial. In an embodiment the user input 510 have a cylindrical hole/opening 525 that is coaxial with axis of rotation of the user input as illustrated in FIG. 6. In an embodiment the user input 520 may be illuminated such that the opening 525 glows in an attractive and oft informative manner such that the illumination patterns could be employed to convey the status of the system. The user input 520 may be configured to correspond with the display 514 such that manipulation of the user input causes corresponding changes in the display 514. The user input 520 may provide/receive a plurality of input movements, such as for example, rotation, speed of rotation, push and click, click duration, double click, and the like.
The control unit 510 may further comprise an electronic visual display 514, either digital or analog, for visually outputting information to a user. Additionally, it should be noted that an embodiment may comprise a plurality of visual outputs, and other components of the control unit 510, such as the user input 520 may be configured to output visual information. Analog visual outputs may be provided by components such as bulbs and the like. Digital visual outputs may be provided by components such as, liquid crystal displays, light emitting diodes, electro-luminescent devices, to name a few. In an embodiment, the control unit 510 may further comprise an electronic audible device 516, either digital or analog, for audibly outputting information to a user. Additionally, it should be noted that an embodiment may comprise a plurality of audible outputs, and other components of the control unit 510 may be configured to output audible information. Analog audible outputs may be provided by components such as speakers, mechanical clicks, etc. Digital audible outputs may be provided by components such as, piezo-electric circuits and speakers. It should also be appreciated that the housing 12 may be configured to be substantially weather resistant such that it can be installed and used outdoors. It will be appreciated that the controller 510 may be electronically and directly connected to a plumbing system, such as an irrigation sprinkler system, that may have at least one electronically actuated control valve for controlling the flow of water through the plumbing system. Additionally, the controller 510 may be configured for sending actuation signals to the at least one control valve thereby controlling water flow through the plumbing system in an efficient and elegant manner to effectively conserve water while maintaining aesthetically pleasing or healthy landscapes. It should be understood that in an implementation, the controller 510 may further comprise memory for recording irrigation iteration data for a plurality of iterations after a plurality of irrigation protocols have been executed. In an implementation, the controller 510 of a system and method may further record irrigation iteration data into memory in case communication with an irrigation server is interrupted.
FIG. 6 illustrates a first side view of a controller 510 showing the coaxial relationship of the axis of rotation of the annular user input 520 with the opening 520. As can be seen in the figure, an axis of rotation 555 corresponding to the annular user input 520 is coaxial with the cylindrical opening 525 that is illustrated with phantom lines. It will be appreciated that the opening may have an opening that is not cylindrical in shape. Whatever shape is chosen for the opening may have an axis of rotation such that it can be aligned with the axis of rotation of the user input.
FIG. 7 illustrates a second side view of a controller also illustrating from the opposite side the axis 555 of rotation of the user input 520 is coaxial with the axis of the cylindrical opening 525.
FIG. 8 It will be appreciated that implementations of the disclosure may comprise or utilize a special purpose or general-purpose computer, including computer hardware, such as, for example, one or more processors and system memory as discussed in greater detail below. Implementations within the scope of the disclosure also include physical and other computer-readable media for carrying or storing computer-executable instructions and/or data structures. Such computer-readable media can be any available media that can be accessed by a general purpose or special purpose computer system. Computer-readable media that store computer-executable instructions are computer storage media (devices). Computer-readable media that carry computer-executable instructions are transmission media. Thus, by way of example, and not limitation, implementations of the disclosure can comprise at least two distinctly different kinds of computer-readable media: computer storage media (devices) and transmission media.
Computer storage media (devices) includes RAM, ROM, EEPROM, CD-ROM, solid state drives (“SSDs”) (e.g., based on RAM), Flash memory, phase-change memory (“PCM”), other types of memory, other optical disk storage, magnetic disk storage or other magnetic storage devices, or any other medium which can be used to store desired program code means in the form of computer-executable instructions or data structures and which can be accessed by a general purpose or special purpose computer.
A “network” is defined as one or more data links that enable the transport of electronic data between computer systems and/or modules and/or other electronic devices. When information is transferred or provided over a network or another communications connection (either hardwired, wireless, or a combination of hardwired or wireless) to a computer, the computer properly views the connection as a transmission medium. Transmission media can include a network and/or data links, which can be used to carry desired program code means in the form of computer-executable instructions or data structures and which can be accessed by a general purpose or special purpose computer. Combinations of the above should also be included within the scope of computer-readable media.
Further, upon reaching various computer system components, program code means in the form of computer-executable instructions or data structures can be transferred automatically from transmission media to computer storage media (devices) (or vice-versa). For example, computer-executable instructions or data structures received over a network or data link can be buffered in RAM within a network interface module (e.g., a “NIC”), and then eventually transferred to computer system RAM and/or to less volatile computer storage media (devices) at a computer system. RAM can also include solid-state drives (SSDs or PCIx based real time memory tiered storage, such as FusionIO). Thus, it should be understood that computer storage media (devices) can be included in computer system components that also (or even primarily) utilize transmission media.
Computer-executable instructions comprise, for example, instructions and data, which, when executed at a processor, cause a general purpose computer, special purpose computer, or special purpose processing device to perform a certain function or group of functions. The computer executable instructions may be, for example, binaries, intermediate format instructions such as assembly language, or even source code.
Those skilled in the art will appreciate that the disclosure may be practiced in network computing environments with many types of computer system configurations, including, personal computers, desktop computers, laptop computers, message processors, hand-held devices, multi-processor systems, microprocessor-based or programmable consumer electronics, network PCs, minicomputers, mainframe computers, mobile telephones, PDAs, tablets, pagers, routers, switches, various storage devices, commodity hardware, commodity computers, and the like. The disclosure may also be practiced in distributed system environments where local and remote computer systems, which are linked (either by hardwired data links, wireless data links, or by a combination of hardwired and wireless data links) through a network, both perform tasks. In a distributed system environment, program modules may be located in both local and remote memory storage devices.
Implementations of the disclosure can also be used in cloud computing environments. In this description and the following claims, “cloud computing” is defined as a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned via virtualization and released with minimal management effort or service provider interaction, and then scaled accordingly. A cloud model can be composed of various characteristics (e.g., on-demand self-service, broad network access, resource pooling, rapid elasticity, measured service, or any suitable characteristic now known to those of ordinary skill in the field, or later discovered), service models (e.g., Software as a Service (SaaS), Platform as a Service (PaaS), Infrastructure as a Service (IaaS)), and deployment models (e.g., private cloud, community cloud, public cloud, hybrid cloud, or any suitable service type model now known to those of ordinary skill in the field, or later discovered). Databases and servers described with respect to the disclosure can be included in a cloud model.
Further, where appropriate, functions described herein can be performed in one or more of: hardware, software, firmware, digital components, or analog components. For example, one or more application specific integrated circuits (ASICs) can be programmed to carry out one or more of the systems and procedures described herein. Certain terms are used throughout the following description and claims to refer to particular system components. As one skilled in the art will appreciate, components may be referred to by different names. This document does not intend to distinguish between components that differ in name, but not function.
