MERMEC diagnostic system is able to check the operating conditions of the Eurobalise, detecting any possible anomalies in the ground plants (i.e. degraded balise). Moreover, the diagnostic system tele-powers the Eurobalise processing the telegram received. It acquires and digitizes the major lobe of the balise radiation pattern as well as registers the "length of contact" intervening between the balise interception and the bit stream receipt (telegram acquisition).
The diagnostic system "Acquisition and Processing Unit (AUPU)" is able to measureevaluate:
- distance between balises
- functioning status of balises
- functioning status of encoder/cables connected to balises
- type of detected balises.
The AUPU unit contains a database storing the following information:
- all information points (IP)
- for each IP: type, balises number and typology, related plant
- all telegrams associated with each balise.
