10 openETCS Model The openETCS model or rather, according to Figure 7.1, the openETCS formal specification is the CIM of the case study. As already discussed in Section 7.1, the modelling of the complete ETCS specification would exceed the limits of this work and this case study by far. Therefore, only a sub-subset of the ETCS SRS is modelled here. Nevertheless, the limitation to certain ETCS Modes and Application Levels emerged to be not sufficient to gain an openETCS model that is small enough to be manageable in this dissertation. Hence, not all functionality specified in the SRS for the used ETCS Modes is modelled. The main goal of the openETCS model is to give an example that is executable in a simple but adequate simulation environment. This simulation is described in Chapter 11. The reduction of used functionality is mainly related to the modelling of data flows. It should be noted that parts of the SRS that are not modelled for the case study are not always emphasised in this document since ETCS is primarily used as an example of a train control system. Another certain remark is that not all parts of the model are presented in this chapter because those are mostly graphs, which all together would require extensive space. The complete model can be found in Appendix C. This chapter presents exemplary diagrams of the openETCS model in the order of the top-down structure of the meta model graph types in Figure 7.2. The description starts with the so-called root graph for the ETCS Modes and transitions, which is followed by data and control flows for each combination of ETCS Mode and Application Level. Afterwards, the extraction of data from incoming balise telegrams is described and the models of the used ETCS language elements are presented. Finally, possible concepts of extending models in respect to safety properties are discussed. 10.1. ETCS Mode and Transition Matrix Although the GOPRR or GOPPRR meta meta model does not define or require a certain root graph, the gEVCStateMachine graph type can be interpreted as such because it must exist exactly once in an openETCS meta model (see Subsection 7.5.1) and all other graph instances are connected with it via decompositions and explosions (see Section 7.2). The modelled transition matrix of the used ETCS Modes (compare Section 7.1) is shown in Figure 10.1. 179
