EMI immune probe design exploration and implementation
Balise is a wireless transponder used as a beacon in many train signal systems in the world, Among them, the European system: ERTMS. This system has been designed for optimal performance and availability. Balise is exposed to a harsh environment, where there’re different types of debris, e.g. metal objects, iron ore, clear water, salt water. These debris together with temperature cycling would have impact on Balise’s uplink characteristics.
Therefore, during the design and development, the Balise transmission performance needs to be measured and evaluated. However, the traditional measurement tool suffers from lab EM disturbance.
Problem description and goals
The focus of this master thesis is the architecture design and implementation of an EMI immune measurement tool, to measure and characterise the transmission flux of a Balise or Antenna, then transfer the signal via optical fibre to PC for signal processing.
Within the required responsibilities you should:
- Based on system level specifications, establish block level specifications, identify key-problem and propose/analyse different architectures that would meet specifications.
- Based on block level specifications, select and justify the components which will together build up the measurement tool.
- Compare and analyse the measurement result with DSP between the traditional measurement probe and the EM immune measurement probe.
For this thesis work we would like to have students who are in the study of M.Sc. in Electronics, Photonics, or Physics with good theoretical knowledge and proven practical experience in the following areas:
- Lab activities
- Electronics design
- Signal processing
- Fluent in English
