UNE-EN IEC 62290-3:2019

This part of IEC 62290 specifies the system architecture for Urban Guided Transport Management and Command/Control systems (UGTMS) as defined in part 1 and 2, and the allocation of functions and requirements defined in part 2 to the different UGTMS subsystems (designated as system constituents in parts 1 and 2), for use in urban guided passenger transport lines and networks.This part of IEC 62290 is applicable for new lines or for upgrading existing signalling and command control systems.This part of IEC 62290 is applicable to applications using:" continuous data transmission" continuous supervision of train movements by train protection profile " localisation by reporting trains, and optionally by external wayside equipment for non-reporting ones (e.g. in case of mixed operation or degraded operation)This standard is not applicable to existing command and control systems or projects in progress prior to the effective date of this standard.The functional allocations of the UGTMS subsystems are mandatory (forming a sort of core system) or optional, according to the mandatory/optional functions and requirements defined in part 2.This part of the standard is applicable as a basis to define FIS and FFFIS. For specific applications, some elements may be added to meet the requirements coming from additional functions or equipment.
