摘要： A cleaning cycle generator for an irrigation system having a programmable irrigation controller. When the irrigation controller terminates an on cycle, the cleaning cycle generator of the present invention will initiate a time delay after which it will turn the sprinklers completely on for a timed period. The sprinklers will then be turned off to complete the remainder of the off cycle. The present invention is particularly advantageous in pressure regulated irrigation valves where particles in the water can become trapped between valve seat surfaces that are in close proximity due to the pressure regulation. Leaking throughout the lengthy off cycle of the irrigation system is prevented by flushing out particles while the valve is in the completely open, unregulated state.

摘要： A two conductor hard wired communications link accepts an actual value of at least one parameter of interest from an environmental sensor in the form of data encoded on the conductors via current modulation. The sensor is mounted in location remote from an irrigation controller. A circuit connected to the sensor transmits an RF signal representing an actual value of a parameter of interest detected by the sensor. A data relay is connected to the hard wired communication link of the irrigation controller. The data relay includes a receiver that receives the RF signal, and circuitry configured to extract the actual value of the parameter of interest and emulate a predetermined set of physical and protocol properties of the hard wired communication link of the irrigation controller.
