摘要
A system for the remote control of a plurality of control units (A11.. A1n... An1... Ann) for irrigation devices is described; the system includes a data processing device (1, B1...Bn) for setting data regarding the duration and frequency of the irrigation periods of the irrigation devices associated to the control units and their position in time. The data processing device (1, B1...Bn) includes a database (11) with archives containing the list of the control units of said plurality and data regarding their operation. There are control means for the control units allowing to send a command regarding the duration of the irrigation time periods and their position in time to the control units in reply to the data set in the data processing device (1, B1...Bn); the control means include at least one module (C1...Cn) provided with a telephone interface (15) for sending the set data to the control units of the plurality of control units (A11..A1n...An1...Ann). Each control unit of the plurality of control units (A11..A1n... An1... Ann) is battery powered and includes a telephone interface (20) for receiving the data deriving from said at least one module (C1...Cn); each telephone interface of the control units is active in a time window (T1...Tn) having a limited duration and each time window (T1...Tn) has a different time position as compared to the time window of another control unit of the plurality of control units. The at least one module (C1...Cn) is adapted to send the set data to each control unit of said plurality of control units only during said activation time window of the telephone interface of the control unit.
