formulas for the flow and how
calculation is made for linearization.
- Local monitoring equipment - based on
microcontroller which shall be
connected by cable with local
environment parameters acquisition
systems.
This equipment is presented in Fig. 2 and
shall accomplish the following function:
- acquisition and monitoring of
analogical signals from the
transducers;
- acquisition and monitoring of
digital input parameters;
- enabling of digital outputs
(signalization of alert/ pre-alert
thresholds overflow);
- long distance transmission of data
(full duplex RS 485 serial port, or
radio/GSM/GPRS) to server;
Figure 2. Local monitoring equipment
Central level – center of monitoring and
control; web server
At this level it will be organized the control
and monitoring center, where the PC-system
with complex functions of Data Server which
contain the Database, the dispatcher for
receiving environmental parameters, the
software applications meant to management
(introduction of information concerning the
technical state of the infrastructure, other
additional useful information in risk
management, alert management) shall be
installed. From a conceptual viewpoint, the
web Server is placed at central level too, but
it can be installed in the same location or at
distance. On the web server will be installed
applications which will select information
from the database for user services delivery
through an Informatics Portal, accessible on
static devices (PC, informatics kiosk) or
mobile devices (PDA, mobile phone).
The environment parameters acquisition devices
will be transmitted by radio modem or
GSM/GPRS. These will be transmitted
periodically by the monitoring local equipment
and when an event occurs (according to
achieving pre-alert thresholds) and will be stored
in the local database. The local database will be
replicated periodically on the Web Server, thus
ensuring a reliable functioning).
The project also proposes a dissemination
system and information services addressed to
population, mass media and organizations.
Software subsystem for multimedia platform for
flood risk monitoring consist in programs for
supervision and evaluation; geological data base;
data base management application; GIS
application developed for interactive
presentation on digital map of objects and
evacuation routes in pilot routes, risk maps and
hazard maps of pilot zone; pilot zone risk and
hazard maps; system’s Portal for information
and flood risk management – it integrates all
system’s functional components.
The system has service oriented architecture
and will provide:
- integration of all relevant functions and
processes ensuring investments
protection;
- Integration of the existing systems into
the new platform;
- Minimizing risk, quick reaction to
change of requirements;
- Reduced complexity due to the interface
built on specific system integrated services;
- Using XML, XSL, SOAP, UDDI,
WDSL and HTTP;
Flexibility;
- Reliability, possibility to extend the
system according to specific needs;
- Scalability;
- Reduced costs and increased
productivity through quick transfer of
applications on any platform.
