The present disclosure is related to a smart irrigation system that includes a first sensor configured to monitor a moisture level at a location and a second sensor configured to monitor a contamination level within a fluid. The smart irrigation system also includes one or more processors configured to receive a first signal from the first sensor, receive a second signal from the second sensor, and route the fluid to the location in response to the first signal indicating that the moisture level is below a moisture threshold and the second signal indicating that the contamination level is below a contamination threshold.

A surge irrigation system with one or more valve location units configured for location at a flood irrigation valve assembly. Each valve location unit has an elongate linkage with a rod configured to rotatably open and close a flood irrigation valve assembly with a powered actuator. A control unit is connected to the powered actuator and configured to wirelessly receive instructions to operate the powered actuator. Various embodiments also implement a base station to relay information and/or instructions between valve location units and a user. A user may control the system through, for example, a mobile device interface. Embodiments of the invention may also include moisture sensors configured to provide feedback to the system. A method of using the surge irrigation system is also disclosed.

A method for watering plants using a self-contained high pressure distribution system with a water reservoir. A mini gear pump is used for pumping water to pressure compensated drip emitters at individual plants. A method for monitoring soil moisture content and programming of individual watering of plants through an energy efficient wireless networking system. The high-pressure water in the plant watering system is used as a communication physical channel for the wireless networking for improving wireless communication range and battery life of wireless terminals. Chip-level Differential Encoding based Spread Spectrum signaling is used for reducing wireless networking solution cost, improving wireless link budget, improving immunity to interference, and increasing battery life of wireless terminals.

A center pivot irrigation system is described that includes a controller that makes use of a particular flow rate of input water to deliver differing or variable depths of irrigation to two or more user-defined areas under a pivot irrigator. The controller operates to pulse control valves for the nozzles/sprinkler heads on and off as the sprinkler arm rotates. The valve pattern along the span of the sprinkler arm is chosen during each operating cycle such that the total water flow through all the open valves matches the flow rate of the input or supply water to the pivot irrigator. To ensure the variable application depth, the speed may be changed during valve duty cycles. A farmer may define an irrigation plan that defines the variable rate irrigation (VRI) zones and also defines exclusion or no spray zones in which no irrigation should occur.

An adaptive hydraulic control system controls irrigation system zones using predicted valve behavior, measured pressure, recovery time, and measured flow. A pressure sensor can measure a pressure in a water line and a flow meter can measure a flow rate in the water line. The adaptive hydraulic control system monitors the pressure and the flow rate, and determines when the pressure and the flow rate are above and below target operational thresholds. When the pressure is determined to be below a minimum target threshold or the flow rate is determined to be above a maximum target threshold, the adaptive hydraulic control system identifies one or more valves in an opened position of the plurality of valves that when closed would cause the pressure and the flow rate to return within the target operational thresholds. The adaptive hydraulic control system provides instructions to change a position of the one or more identified valves.

A method of wirelessly transmitting alarm condition information is applicable to an irrigation zone including a zone input conduit connected to a main distribution conduit of the irrigation system. The zone further includes a zone distribution conduit, a zone valve connected between the zone input conduit and the zone distribution conduit, and at least one irrigation emitter connected in the zone distribution conduit. The method includes detecting an alarm condition at the irrigation zone, and at a designated time proximate to one of a start time and an end time for to an irrigation session for the irrigation zone, controlling the zone valve according to a zone valve control sequence corresponding to the detected alarm condition. The zone valve control sequence comprises a predefined pattern of open and closed states of the zone valve over time.

Disclosed embodiments can provide a system and method for controlling irrigation schedules for a sprinkler system for at least one irrigation zone. The embodiments include automatically updating irrigation schedules based at least in part on watering restriction data from a water authority, such as a water utility authority, and water usage data for a property including the at least one irrigation zone.

A monitoring system for a mobile irrigation system that monitors the conditions or states of various electrical and/or mechanical components of the irrigation system and alerts an operator or automatically takes corrective action when conditions that may adversely affect operation of the irrigation system are detected. The monitoring system also monitors and records the locations of the irrigation system as it monitors the conditions or states of the electrical and/or mechanical components.

Embodiments of the present disclosure provide systems and methods for controlling water flow in a water distribution system (e.g., irrigation system). In an irrigation system, an interrupt controller may receive control signals from an irrigation controller and data from sensors disposed in the irrigation system, and modify operations of components in the irrigation system based on the sensor data. Based on the analysis, the operation of the irrigation system may be interrupted or modified to optimize the supply of water. The interruption of the irrigation system may be controlled by shutting off the water supply to the entire irrigation system.
