The present invention relates generally to agriculture and irrigation of plants. A watering system comprising a master unit and one or more node units are able to carry out bidirectional communication via a power control bus, which may be a coaxial cable. The power control bus provides power and data communication to one or more node units. The one or more node units are configured to receive, carry out actions, or respond to queries from a master unit. Actions that may be taken by one or more node units may include the operation of irrigation valves and query of data related to moisture or other chemistry of a plant growing soil. A master unit may connect to an internet cloud via Wifi or other communication method, wherein a watering system of the present invention may be operable based on at least one data from an internet cloud.

Systems, user interfaces, and methods related to irrigation control systems are provided herein. In some embodiments, an irrigation control system includes an irrigation management application which, when executed by an electronic device, causes a user interface to be displayed to a user. The user interface includes features that permit a user to do one or more of configure, monitor, program, control, adjust various components and/or operations of the irrigation management system.

An irrigation management system which allows for modulation of the watering gradient along crop rows. The system may include dual drip lines which allow for selection of gradients based upon the time each of the dual lines is active. The system may utilize pressure sensitive valves which select drip lines based upon the inlet feed water pressure. The system may include drip emitters which modify flow rates based upon inlet feed water pressure.

An irrigation water amount measurement apparatus 10 includes: a sensor data obtaining unit 11 that obtains sensor data for specifying soil moisture contents of sections of an agricultural field, from moisture sensors installed in the respective sections; an irrigation water amount measurement unit 12 that measures a supply amount of irrigation water supplied from a drip irrigation system during a period from start to end of irrigation in the entire agricultural field; an irrigation time specifying unit 13 that specifies a period of time during which irrigation water was supplied to the section based on a change state of a soil moisture content of the section; and a calculation processing unit 14 that calculates a supply amount of irrigation water supplied to the section, based on a period of time specified for the section, a period from start to end of irrigation, and a measured supply amount.

A watertight electrical compartment for use in an irrigation device can include a compartment body having a chamber and a sealing section configured to mate with one or more sealing rings. A sealing cap can mate with the sealing section and/or the sealing rings to seal the chamber. A cap retainer can be advanced over at least a portion of the sealing cap. One of the compartment body and cap retainer can have internal threads to be screwed onto external threads of the other one of the compartment body and cap retainer. The cap retainer can also have a stopping feature to keep the sealing cap in its sealed position. The watertight electrical compartment can be used in a wireless flow sensor assembly, a battery operated irrigation controller, and/or a battery-operated central controller device, to provide irrigation control, and/or sensor information, without the need for AC power.

A control module for a water harvesting system can be operatively connected to a water level sensor in a water collection cistern, the pump/master valve (P/MV) output port of an irrigation controller, a pump start relay that controls a pump coupled to the cistern, and a pair of master valves that are coupled to station valves for delivering water to a plurality of sprinklers. The control module uses a processor, a plurality of switching circuits, and an operational program stored in a memory to cause the landscape vegetation to be watered with water from the water collection cistern or a municipal water supply, depending on the level of water detected in the water collection cistern. The control module can include a display that can indicate a graphic depiction that represents an actual level of the water in the water collection cistern.

An irrigation system comprises an irrigation controller that receives user input and provides a power signal and command and message data to an encoder. The encoder encodes the command and message data onto the power signal to provide a data encoded power waveform that is sent over a two-wire path. The irrigation system further comprises one or more decoders in communication with the two-wire path to receive the data encoded power waveform and one or more irrigation valves in communication with the one or more decoders. The data encoded power waveform provides power to the decoders and the decoders decode the command and message data from the data encoded power waveform to control the irrigation valves according to the user input.

The present invention provides a system for aligning drive towers within an irrigation system. According to a preferred embodiment, the present invention includes a system and method for cascading alignment of independent drive systems. According to a preferred embodiment, a preferred method may include the steps of: transmitting controller timing data to the first intermediate drive tower and the second intermediate drive tower; assigning a first correction time slot to the second intermediate drive tower; assigning a second correction time slot to the first intermediate drive tower; receiving first alignment data by the second intermediate drive tower; receiving second alignment data by the first intermediate drive tower; performing a first alignment correction based on the first alignment data received by the second intermediate drive tower; and performing a second alignment correction based on the second alignment data received by the first intermediate drive tower.

A vehicular control system includes sensors such as IoT (internet of things) sensors that can share data with other vehicles and that can communicate with the cloud to provide intelligent handling of the irrigation system.
