SCI-CC-A: railway communication protocol

  »  Our projects   »   SCI-CC-A: railway communication protocol

The purpose of the project is to design and develop a Standard Protocol (SCI-CC-A) promoted by ADIF (Administrator of Railway Infrastructures of Spain) for communications between the Centralized Traffic Control Centers (CTC) and the various equipment and signals of traffic present on the track, which make up the railway interlocking systems.

The SCI-CC-A standard is based on TCP / IP protocols applicable to network communication that allows establishing a connection and data exchange between two computers, providing reliable data transport.

In this case, from the CTC to the interlocking system (commands to interlock, enable and cancel road blocks, authorizations, signaling, entry and exit destinations, opening and closing of the level crossing, among others); and from the interlock to the CTC (status of equipment that is connected to the interlock such as signals, needles, wire changers, level crossing, track gauge changer, object drop detector, among others).

This protocol is thinking of serving all of Spain. The objective of ADIF is that all suppliers that develop CTCs and interlocking systems present in the country, can homogenize their communications and be compatible with each other, regardless of the manufacturer, by using a single protocol that facilitates this management.
