BS PD CEN/TS 13149-7:2015 specifies the general rules for an on-board data communication systembetween the different systems that may be used within public transport vehicles. This includesoperational support systems, passenger information systems, fare collection systems, etc.This Technical Specification describes:
- the requirements for an on board IP network;
- the overview architecture and components for an IP based on-board network;
- the modular structure of the network architecture;
- the Service Oriented Architecture (SOA) approach, and approach to defining services.
Systems directly related to the safe operation of the vehicle (including propulsion management, brakesystems, door opening systems) are excluded from the scope of this Technical Specification and aredealt with in other standardization bodies. However, the architecture described in this TechnicalSpecification may be used for support services such as safety information messages. Interfaces tosafety-critical systems should be provided through dedicated gateways with appropriate securityprovisions; for the purposes of this Technical Specification, these are regarded as simply externalinformation sources.This Technical Specification is designed primarily for vehicles with a fixed primary structure, wherenetworks can be installed on a permanent basis and the system configuration task consists largely ofthe integration, adjustment or removal of the functional end systems that produce and/or consumedata. Public transport vehicles consisting of units linked temporarily for operational purposes(specifically, trains in which individual engines, cars or consists are routinely connected anddisconnected) require additional mechanisms to enable the communications network itself toreconfigure. Such mechanisms are provided through other standards, notably the IEC 61375 series. (Seealso 5.9.)
