15、 Group SC9XB/SGB1 conclusions From the conclusion of the works of Survey Group SC 9XB/SGB1, in document CLC/SC9XB(Sec)174 (Bibliography 9), a series of standards is to be prepared, with the following guiding principles: the overall objective is to develop standards for data exchange involving railwa
16、y vehicle consists, between themselves or with fixed installations; standardisation is focussed to what is necessary for implementing interoperability as defined in Directive 2001/16/EC (on the interoperability of the Trans-European conventional railway system), and as will be specified by the bodie
17、s in charge of drafting Technical Specifications for Interoperability (TSI); the scope of the work is then limited to international Passenger trains and freight trains in The Trans-European conventional rail system, excluding the signalling and control-command subsystem. This does not explicitly exc
18、lude High Speed Trains (HST), but excludes formally trams, metros and urban or suburban trains. Separate functional standards will be established for freight and Passenger trains. Requirements for interoperability, including those specified in a set of Technical Specifications for Interoperability (
19、TSI), are different for these two categories of rolling stock. The series of standards has been structured as follows, with four categories: - STD1: data dictionary and rules for functional standardisation; - STD 2: functions in freight traffic (for a selected set of functions); - STD 3: functions i
20、n passenger traffic (for a selected set of functions); - STD 4: standardisation of communications procedures. This document is the first part, in category STD1, of the series of functional standards, aiming to define a common modelling framework, to be used for the development of the subsequent stan
21、dards: common methods and rules, a unique Reference Architecture, and common Data Dictionary. The Trans-European conventional rail system Trans-European conventional rail system shall be considered as defined in Article 2 of the Council Directive 2001/16/EC on the interoperability of the Trans-Europ
22、ean conventional railway system: For the purposes of this Directive: “Trans-European conventional rail system“ means the structure, as described in Annex I, composed of lines and fixed installations, of the Trans-European transport network, built or upgraded for conventional rail transport and combi
23、ned rail transport, plus the rolling stock designed to travel on that infrastructure. The Trans-European rail system is broken down into subsystems, as described in Annex II of the Directive: a) structural area - infrastructure, in particular access / egress points that define the boarders of an inf
24、rastructure managed by a given organisation, and also shunting, freight terminals and stations, - energy, electrification system, - control and command and signalling, to command and control train movement, - traffic operation and management, including train driving, traffic planning and management,
25、 CLC/TR 50501-1:2007 4 - rolling stock, including all train equipment and man-machine interfaces for driver, on-board staff and passengers. b) operational area - maintenance, including logistics centres for maintenance work and reserves for corrective and preventive maintenance, - telematics applica
26、tions: freight services and passenger services (including passenger information, reservation and payment, luggage management, connections between trains and other modes of transport). Examples of functions to be standardised NOTE In the following informal function descriptions, interface ”type B” (“
27、train level to consist level”, named also “train to consist” for short), and interface ”type C” (train to ground) are used (see Figure 1 in 4.4.2). 1) Dynamic passenger information system. Refer to 14, a contribution of TrainCom European Research Project (ref: IST-1999-20096), proposing a detailed X
28、ML specification of messages that are exchanged between vehicles and with the ground. This specification covers all characteristic features of the rail environment, including its dynamic aspects. 2) Maintenance: Euromain European Research Project (ref: IST-2001-34019) proposes detailed XML specifica
29、tions for data, and including the definition of functions for real time monitoring, data collection and statistics. 3) Passenger emergency brake: The Technical Specification for Interoperability (TSI) relating to the rolling stock subsystem (High Speed) gives requirements for this function. This is
30、a train level function. If the train is formed by several coupled consists, an interface “train to consist” (type B) is involved. A communication with the ground is also possible: interface “train to ground” (type C). 4) “Stabled ready for use”: This is a train level function, ensuring that a train
31、composition is ready for service when required. If the train is formed by several coupled consists, an interface “train to consist”, (type B) is involved. A communication with the ground is also possible for triggering train preparation: “ground to train” interface (type C). 5) Control of passenger
32、lighting: Control of lighting from the driver cab, for two consists coupled together. There are in addition some local controls in each coach. Level of services for the lighting system may be different for the two consists - version 1, with two levels of lighting: full, reduced, - version 2, with th
33、ree levels of lighting: full, reduced, and night. The issue raised by this example is one problem of interoperability among a set of heterogeneous consists. EXAMPLE When the driver is in the consist which is fitted with version 1, how to specify the interface between consists, in order to have an ac
34、ceptable behaviour in the other consist fitted with version 2. Two alternative solutions are - each consist should be able to interpret in its own way every possible command issued by another leading consist. For instance, a consist fitted with version 1 will set “reduced level” when receiving a “ni
35、ght level” command, - the driver could control each consist after having “imported” on the cab MMI the specific control interface of the given consist. CLC/TR 50501-1:2007 5 6) Train integrity (completeness of train) Some possible solutions to check the completeness of the train may use - connector
36、at the end of the train, - with GPS + EGNOS, precision -classes defining the behaviour. CLC/TR 50501-1:2007 27 Activities: - for each interface: define functions for the received messages; - for each interface: define attributes for data exchanged through the interface periodically. (Formally, the u
37、se of attributes in an interface is a violation of the UML 1.4 definition, but with UML 2.0 this will also be allowed. It is also allowed presently by some UML tools); - define classes for all data structures used as parameters or structures that are used for configuration; - define classes which re
38、alize the components interfaces, with all necessary attributes and functions; - the class diagram below, in Figure 5, shows the detailed interfaces of the EmergencyBrakeControl-component from above; - the interfaces are identical to those shown in the component diagram above; - the classes shown bel
39、ow all reside in the component EmergencyBrakeControl and the class BrakeControl realizes the EmergencyBrakeControls interfaces; interfaceAlarmOutput+ activateAlarm ( )interfaceDriverEB+ activateEmergencyAlarm ( )+ recordAlarmMessage ( )+ activateBrake ( )+ releaseBrake ( )interfacePEHUInput+ handleO
