COMMUNICATION SYSTEM BETWEEN CONTROL UNITS FOR IRRIGATION DEVICES
First Claim
1. A communication system between a main control unit for irrigation devices and at least one secondary control unit for irrigation devices, specifically for battery powered control units, each control unit including a module for the transmission of data to the other control unit and for the reception of data from the other control unit, said main control unit and said at least one secondary control unit including means adapted to allow the power supply of said data transmission and reception modules only during the time periods required for the exchange of data between the main control unit and at least one secondary control unit, wherein it includes a cable connected between the module for the reception and transmission of data of the main control unit and the module for the reception and transmission of data of the at least one secondary control unit and a further cable connected between the main control unit and the at least one secondary control unit, said main control unit or said at least one secondary control unit being adapted to enable said further cable by sending thereon the information regarding the request for data communication between said main control unit and said at least one secondary control unit and being adapted to disable said further cable once the data communication is finished.

Abstract
A communication system between a main control unit (100) for irrigation devices and at least one secondary control unit (A1 . . . An) for irrigation devices, specifically for battery powered control units, is described; each control unit (100, A1 . . . An) includes a module (10, 20) for the transmission of data to the other control unit and for the reception of data from the other control unit. The main control unit (100) and the at least one secondary control unit (A1 . . . An) include means (4) adapted to allow the power supply of said data transmission and reception modules only during the time periods (T, T1 . . . Tn) required for the exchange of data between the main control unit (100) and the at least one secondary control unit (A1 . . . An).
