PD CLC/TR 505421:2018CLC/TR 50542-1:2018 4 Introduction The purpose of this Technical Report is to propose harmonization for communication between
23、 the displays on the drivers desk and the train onboard systems. The need for this harmonization has grown out of several trends. One trend is that the rolling stock is being computerized more and more, enabling sophisticated functions within various train onboard systems. Furthermore, the drivers d
24、esk of such rolling stock is built around one or several computerized displays. These allow the driver to interact with rolling stock functions and train onboard systems. The user interfaces are typically user friendly, featuring e.g. graphics and colours. In case of degraded situation (display fail
25、ure) and with several displays available on the desk, it should be possible to relocate important information to a display that is still working. This improves operational availability. A second trend is the ongoing harmonization of the interfaces on the train. A third trend is that a European marke
26、t is opened for onboard equipment. Traditionally, some onboard equipment are linked to a country and/or to a rolling stock type. This has effectively limited the rolling stock to operate within a limited number of countries. The two trends above are useful to reduce this limitation. The combination
27、of the above trends leads to the conclusion that during train operation, train onboard systems need to have access to the displays on the desk. Furthermore, it is desirable to maintain the advantages of multi-display installations, allowing the ability to switch to another display in case of display
28、 failure. Thus a certain level of integration and harmonized communication is required. Another motivation for this Technical Report is related to the Life-Cycle Cost. The recommendations written here support the easier replacement of displays and desk equipment during the lifetime of the vehicle, i
29、ndependently of the supplier. In this document the Other Train Systems (OTS), the displays and the Train Display Controller (TDC) are considered only regarding their functionalities and not as physical devices. The CLC/TR 50542 series are not standards but studies on the future view of the system. T
30、hey do not describe an existing solution for the Train Display System (TDS).
