Remote control
The installation of remote control and distance control allow for better network management and functioning of elements and integrated equipment.
These systems help us to:
- Know about the variables which inform us about the state of the network (flow, pressure, free chlorine concentration etc), provided by the adequate instrumentation to guarantee its reliability.
- Know about the state of the functioning of the elements and integrated equipment inside drinking water production centres and pumping stations.
- Modify instructions of elements which work automatically.
- Manoeuvre certain elements which are operated in the network at distance.
Data management
Currently all of this is carried out via 348 remote stations, managing 6.100 measuring instruments, 12.000 states and alarms, 2.500 orders y 24 remote control installations, which allow us to carry out works on 200 valves 400 motor-pumps, from the Control Centres located in Delegations and Plants.
The data collected in real time from each one of the remote stations is concentrated in the master centres and managed and visualized in the control centres for interface applications man-machine based on control and acquisition of data systems (software uploaded on a computer which presents data to an operator and over which the process is controlled).
From here data is centralized via the latest information systems and tools which allow for bidirectional links via the internet with web publications which guarantee maximum security, reliability and flexibility, in the remote of the installations.
As well as the management of the remote control systems via a System of control and acquisition of data, the obtained information is analyzed, stored and classified so that it can later be:
- Used to generate statistical reports.
- Analysed in the case of problems to the service.
- Used for the production and updating of mathematical models of the distribution networks of drinking water.
- Carrying out maintenance work.
- Assuring the quality and continuous improvement of process management.
The remote control of the supply system is based on the latest machines or PLCs which have demonstrated reliability in the industrial sector, linked with the master stations via private radio networks, telephonic records, mobile phones (GPRS y GSM), Ethernet networks and fibre optic networks. In the most strategic points of the supply network equipment redundancy and communication channels are incorporated, increasing the reliability and robustness of the functioning.
