  • Patent number: 11053652
    Abstract: The present invention relates to a method for providing watering or non-watering of a specific area of soil through a first plurality of irrigation valves (42). Specific irrigation parameters are measured at the specific area of soil through a second plurality of field sensors (54). A controller unit (30) is interconnected to a third plurality of control units (18). Each control unit is connected to a specific irrigation valve and/or a specific field sensor. A type declaration providing communication under a second communication protocol is transmitted from the controller unit to the third plurality of control units using a first communications protocol. A second set of instructions are transmitted from the controller unit to the third plurality of control units using a second communications protocol. A first set of instructions are transmitted from the controller unit to the third plurality of control units using the first communications protocol.

  • Patent number: 7146255
    Abstract: A two-wire controlling and monitoring system for irrigation of localized areas of soil includes a water pipeline, a plurality of controllable irrigation valves, a plurality of field sensors measuring specific irrigation parameters, and a plurality of localized irrigation control units. Each irrigation control unit has a sensor decoder connected to a specific field sensor and/or a line decoder connected to a specific controllable irrigation valve. The system further includes a controller and power supply unit that applies a first alternating DC voltage signal to a two-wire cable interconnecting the controller and power supply unit and the irrigation control units. The two-wire cable provides power from the controller and power supply unit to each of the irrigation control units, it transmits schedules of instructions to the irrigation control units through the two-wire cable, and it receives the irrigation parameters from the irrigation control units through the two-wire cable.
