Client-Groundstation Communication

• Based on Http (for Web Browser)
• open standard
• allows any client with an Internet Browser to get
  the data
• no problem with firewalls (Http port always
  opened)
• security
• encryption (SSL)
• supported by Java (java.net, javax.servlet)
• easy to implement

Client Architecture

• To add a new service, just reference a new applet
  in the Html page
• Applets will be implemented with the Java AWT
  library (supported equally by all the Internet
  browsers)
• Applet parameters (background color, size) can be
  easily set in the Html with the ltPARAMgt tag no
  need to change the code!

example Upload of Diagnostic Data

• uploaded event data contain following information
  items (extract)
• Fault code
• Start date and time (occurrence of a fault)
• End date and time (disappearance of a fault)
• Subsystem (e.g. "brakes", "auxiliary", ... )
• Fault attributes according to UIC 556 leaflet
• Short text message (max. 40 characters)
• Count (number of faults of this code occurred so
  far)
• Reference to environment data when configured
• Environment data are selected process variables
  being photographed at the occurrence of a fault.
  Absolute maximum limitations of environment data
• Up to 127 different data sets (16-bit words)
  Name, contents, unit
• Pre- and Post-history, max. 255 samples where 1
  sample is taken at the moment of the occurrence
  of the fault.
