  • 17.30 / copy


The CEN 13149 series of products concerns on-board data communication systems on public transport vehicles. This series provides for data services that enable open and managed sharing of relevant information. This document, being Part 9 of the series, specifies a time publication, enabling all on-vehicle services to share a common understanding of current time, based on a suitable agreed master network clock. It covers: - the functional scope, i.e. which data the service provides, why, when and how often. - the transport protocol, i.e. how the data are transmitted. - the service publication, i.e. how the service can be found by other modules or applications - the structure of the data, i.e. how the data are structured and how the data elements are named. This document implements the service framework described in CEN/TS 13149-7.
