Wireless irrigation system
First Claim
1. A wireless irrigation system for controlling the operation of a plurality of control valves each of which controls the flow of water in a corresponding branch pipe leading from a common supply pipe, said system being characterised by a control data generator, a purality of control units and a plurality of power generating means corresponding to each of said control valves and being located adjacent thereto, for generating power in response to the flow of water in a corresponding branch pipe said control units being connected to the corresponding control valve and to the corresponding power generating means, and including decoding means to detect data transmitted from said control data generator which identifies a predetermined one of said control units, and switch means activatable by said decoding means to connect said control valve and said power generating means to operate said corresponding control valve, wherein said control unit has sensing means to sense operational data, and said control unit includes means for transmitting sensed operational data to said data control generator.

Abstract
An irrigation system for controlling a number of control valves (104) is disclosed. The valves (104) control the flow of water in a corresponding branch pipe (102) leading from a common supply pipe (101). The system uses wireless transmission of control signals to operate a control unit (115) which operates the corresponding control valve (104) from a corresponding power generator (107). The control signal is encoded by an encoder (118) according to predetermined conditions and is decoded by each of the control units (115), the coded signal being received by each control unit (115) and the specified control unit (115) operating only.
