overall reference model The term Open Systems Interconnection (OSI) qualifies standards for the exchange

3 Functionality

3.1 General

This clause reviews the principal functions and applications to be performed by the RMCS system

Generally it involves real-time, centralised telecontrol of communal pressurised irrigation water distribution networks, in which, once the water has been made available via reservoirs, interbasin transfer or bore holes, it

distribution network Furthermore, the system needs to store a sufficient amount of information collected from

the network in order to enable both water management and administration of the user collective to be

performed

The main elements subject to telecontrol in communal pressurised irrigation water distribution networks are:

 valves controlling supply of irrigation water to plots;

 water consumption meters on each plot

In addition, it may be possible to telecontrol or telemeasure other elements, such as:

 pressure sensors at different points on the network;

 collection pool level sensors;

 flow meters on primary or secondary pipelines;

 water quality sensors;

 pressure sensors at filters;

 water consumption meters on primary or secondary pipelines;

 flow sensors;

 gates;

 electromechanical equipment (pump sets)

3.2 Basic functions

The basic functions of a RMCS system, performed from the Central Control Unit (CCU) are:

 centralised telecounting of the water consumption of each plot in order to later issue bills;

 centralised telecontrol of the opening and closing of the supply valves to the plots under the direct

orders of the operator or based on a pre-established programme (irrigation shifts);

 centralised telemeasurement of pressure, flow rates and water consumption on primary or secondary

pipelines;

 storage of history data (generation of history files: commands, alarms and measurements) in a

standardised and exportable format

3.3 Specific functions

The specific functions that may be performed by a RMCS system are:

 billing based on the consumption of each plot and configurable parameters;

 telemeasurement of collection pool levels;

 teleindicating of alarms:

 leak detection;

 communication fault;

 teleindication of faults in the mains supply (pumping);

 automatic signalling of alarms;

 automatic control of network pressure
