METHOD AND APPARATUS FOR COMMUNICATING IRRIGATION DATA

摘要

Methods and systems control an irrigation system that includes an irrigation controller, and at least one irrigation sensor connected by a communication circuit. A series of addressing pulses is also generated over the communication circuit, which indicate a device identifier of at least one irrigation sensor. The series of addressing pulses activate at least one irrigation sensor having the device identifier indicated by the series of addressing pulses such that the activated irrigation sensor provides a sensor signal indicative of an irrigation condition to the irrigation controller via the communication network.

1. An irrigation control system, comprising:
a communication circuit; an irrigation controller, comprising:
a processor configured to run an irrigation program,a signal generator configured to generate address information that identifies at least one irrigation sensor and to generate valve control signals for opening and closing an irrigation valve, wherein the irrigation controller is configured to communicate the address information and the valve control signals over the communication circuit, anda data collection module configured to process a sensor signal received via the communication circuit and to execute a control action based on the received sensor signal; at least one irrigation sensor connected to the communication circuit, each of the at least one irrigation sensors associated with a unique device identifier; and a valve actuator configured to receive the valve control signals from the irrigation controller via the communication circuit and open or close a valve based on the valve control signals.
