Measurement of the temperature of the catenary under tension
Description of the use case:
Measurement of the surface temperature of catenary elements (contact wire, claws, clamps) under tension, at a fixed station, over a maximum canto length (1.5 km) and remote data transmission.
- Temperature reading with an accuracy of +/- 1°C
- Autonomy in electrical energy
- Sending data by LoRa radio, usable on the cockpit platform
Device:
The manufacturer MOIZ proposed a sensor with an energy recovery device to be fixed in the groove of the contact wire communicating in LoRaWAN allowing:
- Temperature measurement
- The recovery of solar thermal energy
- The conversion of this energy into electrical energy
- The fixing of the sensor on the electrified wire using claws
The start-up MOÏZ offers a patented thermal energy recovery solution that makes it possible to make connected industrial sensors (temperature, humidity, etc.) used for the maintenance of railway infrastructures (rail, catenary, etc.) completely autonomous in energy. Without batteries, these sensors do not require maintenance. Without wires, they are simple and economical to install. This solution makes it possible to recycle the waste heat lost in industrial processes and infrastructures and to facilitate their digitization in an eco-responsible approach.
The start-up MOÏZ has been involved in the Rail Open Lab since the beginning of 2021. This involvement resulted in the creation of two use cases for which the autonomy of the sensors used was of particular importance.
The Rail Open Lab is an excellent opportunity to confront our technology with the demanding business needs of infrastructure managers and railway manufacturers.
