GPS Sensor for Position Determination
A GPS sensor is integrated in order to be able to precisely determine the position and thus the tension of the contact wire. In addition to the satellite data, the coordinates of a base station are also used for referencing to determine the position with centimeter precision.
Temperature and Humidity Sensors for Icing Data
By measuring the contact wire and outside temperature in combination with measuring the air humidity, possible icing of the contact wire can be determined at an early stage.
In addition, the contact wire temperature is an indicator for the wear of the contact wire.
Accelerometer for Vibration Data
With the help of an acceleration sensor, the vibration dynamics of the module are converted into electrical signals. As a result, impermissible oscillations and vibrations of the contact wire can be detected.
Magneticfield and Distance Sensors for Wear Data
The wear of the contact wire can be determined by measuring the magnetic field around the contact wire and measuring the distance between passing pantographs.
Camera Sensor for Image Data
Depending on the positioning, a camera sensor can be used to direct numerous perspectives onto the overhead line system and the railway line. With the help of image processing, obstacles on the route can be detected. This can significantly improve the control, maintenance and security of the system.
