LOP

Il LOP (Link or Pair) is a technological platform based on wireless short range models characterized by low energy consumption and by a high flexibility of use. This system enables to implement monitoring clusters with knots of much reduced physical dimensions provided with sensitive elements of a different nature for environmental, meteorological, climate and mechanical measurements (stress, displacements and acceleration). The LOP sensors can implement network of the star or mesh with 100 measurement nods at either 2.4 GHz or 866 MHz.

 

MEMS

MEMS (Micro Electro-Mechanical Systems) are integrated components in highly miniaturized form on the same silicon substratum which enable to develop non-invasive sensors of extremely reduced visual impact. Such Microsystems, which combine electronic and mechanical components in only one chip whose dimensions are contained in a fraction of millimeter, are at the basis of special inertial sensors of accelerometer type, whose application is very advantageous within structural monitoring.

 

POF

The POF (Plastic Optical Fibers) technology is based upon principles of photonics applied to light conductors of polymeric type. Such fibers can transmit the digitalized data and – together – act as an integrated sensitive element for the monitoring of static (displacements) and dynamic (acceleration) parameters. The POF based sensors are extremely small, handy and galvanically insulated thanks to the use of plastics. Unlike the glass optic fiber, which operates with the infra-red light and is harmful to the human eye, the plastic fiber works with visible light and – unlike the conventional electric cables – does not emit any elctro-magnetic radiations and is immune to interferences.

 

WSN

WSN (Wireless Sensor Networks) is a set of radio devices which are mutually interfaced to low yield and consumption short range wireless channels. Designed to operate in full autonomy, these networks have at disposal a large number of knots, distributed in a physical space and appropriate to monitor phenomena of a different nature. The WSN’s are associated to sensitive elements and - therefore - are sensorial networks provided with self-learning algorithms whose purpose is to generate a significant improvement to the quality of the information: they can guarantee high fidelity and provide information in real time, even from hostile environment, besides reducing the transmission cost of said information.

 

RFID

The RFID’s (Radio Frequency IDentification) are either active or passive devices provided with the capacity to memorize and communicate, addressed to the automatic identification of objects. The element which characterizes an RFID is the transponder or tag. The tag is an electronic component consisting of a chip and an antenna. The chip, which is of just few millimeters, is the “intelligent” part, consisting of a non-volatile memory which contains a single code, transmitted through the antenna (signal transmission circuit) to the reading apparatus which will check the data received. In the passive tag, the Reader emits an electromagnetic-electric field which – through the induction process – generates a current which supplies the chip in the tag antenna. The powered chip communicates all its information, which is irradiated to the reader through the antenna.
