This part of IEC 62290 specifies the functional requirements specification of UGTMS (Urban Guided Transport Management and Command/Control Systems). IEC 62290-2 is applicable for new lines or for upgrading existing signalling and command control systems.
This part of IEC 62290 is applicable to applications using:
spot or continuous data transmission
continuous supervision of train movements by train protection profile
localisation of trains by wayside equipment or reporting trains.
This standard is not applicable to existing command and control systems or projects in progress prior to the effective date of this standard.
Command and control systems which do not use data communications, between wayside equipment and trains, for train protection purposes are outside the scope of this standard.
In this part 2 of the standard, the functional requirements set the framework to which detailed functions should be added to define any complete application, either generic or specific.
Because of that, this part of the standard is not intended to be used as a basis for the definition of complete SRS, FIS nor FFFIS.
