by a large majority of users during the phase of spatial data production and primary
exploitation, because of the ease of use (compared with the ESRI family products,
such as ArcInfo, ArcView and ArcGIS) and including an impressive number of
specific GIS tools.
Some examples of applications:
– prepare work orders for the network inspection and management;
– identify the valves that should be shut off when a pipe break occurs;
– surveying the activities regarding water losses detection in pipes.
The main advantages of GeoMedia Professional are the following:
– easy to integrate with AutoCad and MicroStation maps specific to CAS S.A.;
– improves the security and lifespan of CAD and GIS data through the consolidation
of CAS S.A. services;
– full potential to integrate the existing CAS S.A. paper maps (scanner A3 → A0);
– potential connection to other information systems within CAS S.A. (SCADA,
accounting programs, client billing, etc.).
6.4 SCADA Technology
Water supply is vital for people. Therefore continuous supervision of water treatment
and water distribution processes is needed in order to maintain the normal functioning parameters or to quickly solve any problem that could appear. SCADA is the
right solution. This acronym stands for Supervisory Control And Data Acquisition.
Basically, it means that various computer-based control systems allow operators to
monitor and control a facility’s equipment either locally or remotely. SCADA may
turn devices and equipment on or off, display real-time operational data, provide
details and views of various processes, display large amounts of data and set alarms.
Proper solutions imply automation and monitoring architectures which contain
[6]: a supervision and control system for the real-time installation, programmable
logic controllers with basic functions (communication, adjusting, measuring), communication systems, interfaces with sensors, electrical drive elements, measuring
devices, etc. (Fig. 6.9).
In Cluj-Napoca, the regional water operator CAS S.A. has started the implementation of its SCADA systems since 2003.
Now, the central dispatcher of Cluj has a complex structure. The core hardware
components are 2 redundant rackable Siemens industrial servers IPC IPC547D (e.g.
i7, 8 GB RAM) with RT licenses, server extensions and redundant extensions. Each
important application/license is associated with a dedicated Siemens industrial PC.
For example, there is one PC for the archive server, one for the WinCC RC license,
one for the Step 7 license, one for the WebNavigator license, one for each OPC
server and one for each WinCC RT 128 client. The entire SCADA platform is made by
Siemens (SIMATIC WinCC 7.0). The communication rack is situated in a climatized
