Communications infrastructure as a temperature sensor

INDRA HAS USED A TECHNOLOGY PIONEER IN ITS APPLICATION TO THE RAIL SECTOR.

Indra is carrying out an innovative pilot project to create a thermal map of the entire Madrid Metro network, in order to study the possible use of this energy, as well as to facilitate the detection of fires or overheating in high-risk areas, among other uses.

The project consists of reusing the existing optical fiber in the infrastructure with minimal intervention at the ends to install a distributed thermal sensor (DTS), which enables the temperature and its variations to be measured with an accuracy of less than 10 meters and 1 degree and a range of up to 60 kilometers to generate that thermal map.

This technology has been used for a decade in other sectors, but Indra is a pioneer in its application to the rail sector, as well as on highways and roads.
