| (54) | Road mirror with heating and alarms |
| (57) Device and method for the confident working and management of the reflecting mirror
used for the extension of the visibility in critical areas of the road runs. The reliability
is obtained through the supervision of the possible environment conditions critical
for temperature and humidity, through supervision of the possible failures of the
heating system (4) and through supervision of the possible drift of the orientation
of the optics (3). Such supervisions are interlaced with alarms (11,12) towards the
user to alert him about the non reliability of the apparatus and/or towards the body
involved in the road signals so that he proceeds with the proper interventions. As
well the proper functioning can be pointed out. This is obtained through a microprocessor
whose inputs are constituted by signals coming from: temperature sensor, humidity
sensor, compass, x inclinometer, y inclinometer, electric supply and set points and
whose outputs are constituted by site luminous alarms and remote alarms via modem
or via radio.
