  • Publication number: 20240260521
    Abstract: In one or more examples of the present disclosure, irrigation control software is provided for a computerized irrigation system. The irrigation control software may provide various user interfaces capable of allowing users to create, assign, organize, and save facility maintenance-related electronic notes to a remote database or central irrigation server that is accessible by mobile devices of authorized users. The electronic irrigation notes may be linked to one or more sprinklers or geospatial areas within the irrigation system, may be assigned to one or more authorized users, may include text or images descriptive or indicative of an issue or a maintenance task associated therewith, and may be archived to create maintenance log histories to help monitor issues associated with specific sprinklers or geospatial areas.

  • Publication number: 20050264973
    Abstract: A large number of irrigation system devices connected to a common two-wire cable can be powered and individually controlled from a central location by transmitting over the cable DC pulses of alternating polarity. Control information is conveyed by transmitting a command pulse train consisting of a series of pulses, separated by short no-power intervals, whose polarities indicate logic ones or zeros. Following a command pulse train, a selected watering station decoder acknowledges receipt of instructions by drawing current during a predetermined pulse of an alternating-polarity power pulse cycle, while a sensor decoder returns binary data by drawing current during one or the other of the alternating-polarity pulses of a series of power pulse cycles.
