Lite4ce: New generation fibre optical sensing technology

From September 18th to 21st at #InnoTrans2018 Thales presents intelligent sensor technology for railways consisting of Lite4ceTM sensor and Lite4ceTM evaluator.

Thales smart fibre optical wheel sensing technology

The application of fibre optical technology eliminates limitations of classic electro-magnetic systems such as electromagnetic interference and enables significant distances between sensors and EAK.

The Thales Lite4ce™ sensor is based on Fibre Bragg Grating technology, which enables sensors on the rail to safely detect a variety of parameters on rolling stocks. These include the safe detection of wheels, the quality of the wheels as well as the speed and weight of vehicles.

Lite4ce™ sensor is equipped with a heat-activated adhesive foil. The sensor is bonded to the rail web using an innovative adhesive device. Calibration or adjustment of the sensor for commissioning, as is necessary with all conventional sensors, is eliminated.

Fibre vs Copper

The exclusive use of fibre optic sensors together with fibre optic cables significantly reduces the investment costs for the track occupacy signalling device.

Lite4ce™ sensing technology eliminates the need for any electronics in the track area or along the track. Instead of the copper cabling as in conventional sensors, the much cheaper fibre optic cabling is used. At the same time, all systems to protect cabling against overvoltage are eliminated. The use of a data transmission system on the fibre optic cable is also not necessary.

Furthermore, the use of Lite4ce™ smart sensing technology enables significant savings in operation costs.

Maintenance of the Lite4ce ™ sensor is not necessary. The energy consumption of the Lite4ce™ track detector significantly decreases compared to conventional systems. The Lite4ce™ sensor is immune to any kind of electromagnetic interference from rail vehicles on the train detection equipment.
