Communication system for multizone irrigation

A multizone irrigation system (230A) includes a central control unit (300) having a central control system (60) interfaced with a central valve (302) and a central communication unit (e.g., a pressure sensor 304). The central valve regulates water flow for irrigation from a water source and can lowe...

More Information
Summary:A multizone irrigation system (230A) includes a central control unit (300) having a central control system (60) interfaced with a central valve (302) and a central communication unit (e.g., a pressure sensor 304). The central valve regulates water flow for irrigation from a water source and can lower water pressure in the pipes using output (301). The central communication unit is constructed to transmit or receive pressure based communication signals providing irrigation information. Each zone includes a sprinkler control unit (2311, 2312 ...231N) including a sprinkler connected to a water pipe for irrigation. Each sprinkler control unit includes a local controller (235) interfaced with a local valve (250) for controlling water flow to the sprinkler. The sprinkler control unit also includes a local communication unit (e.g., a pressure sensor 239) constructed to receive communication signals from the central communication unit and provide received irrigation information to the local controller.
