The present job illustrates the realization of a system, for the monitoring of the
electromagnetic pollution of high and low frequency.
The purpose of the plan is to develop a method of territorial map, the levels of
electromagnetic field (radio frequency and ELF), based on the knowledge of the
distribution of sources on the territory and for the attainment of following
• The Systematic knowledge of the values of electromagnetic field presents
over a territory, showing eventual critical situations;
• The Possibility of a preventive evaluation of the receptivity of
environment at a site regarding the installation of new systems.
The method is based on the use of three instruments:
• The Database of georeferenced sources (systems of radio frequency and
cellular telephony, electrodes);
• the Models of evaluation of the magnetic fields generate from sources;
• the Measures.
For the implementation of the described system they have been used Open-Source
softwares for linux.
For the import and elaboration of the maps it has been applied to the use of
Grass6.1-cvs on Debian distribution. With the use of Debian, they have been exceeds
all the relative problems to you you to the dependencies between the packages that
they constitute Grass.
For the calculus of the electromagnetic Fields and the Volume of respect, generates
from the antenna (norm CEI ), has been used the language of scripting TCL/TK,
integrated in the VTK libraries .
The representation of the electromagnetic Field and the Volume of respect (norm CEI
2), happens through geometric figures in 3D.
The obtained figures therefore come elaborated and exported in format vrml, for
their visualization in Paraview.
All three systems have been integrated, by scripts TCL/TK, in pages PHP, and they
have been visualized by appropriate windows of visualization.
