New techniques of control against the degrade
Inside the
Lupanare
in Pompeii recently restored it has been installed a system with
sensory to infrared
rays for the survey of people.
There are two levels of control:
one of the surfaces and another
of the influx of visitors.
The first one
allows a series of useful investigations
for the evaluation of the state of degrade
of the paintings and of the causes that determine it, through
sensory that notice the
temperature and damp of the environment, of the walls and of the
surfaces, and the percentage of
carbonic anhydride inside the environment. Sensors always send
by radio
the data to a switchboard that gives a sign of alarm every time some
parameters are overcome.
Visitors’ control is made thanks to
infrared cells which send
signs of alarm if more than nine
persons try to enter together.
