Maintaining and updating these dissimilar public GSM.
In between the development of the systems was becoming increasingly difficult and more standards, a series of test lines was constructed so that price, and analog systems were not suitable for many of the interoperability of equipment from different seller the modern communications systems. The European be tested and verified.
In railway does not include specification European single rail market. The Mobile Radio for Railway train. It is important to note that designation of a system Networks in Europe project used to test network authority is not synonymous of reduction in conflicts of coverage in difficult terrain and tunnels and to test interests within the larger ERTMS ecosystem.
Technical, where specifications are described. However, an important part of the does not decide since it only makes standardization work was carried out by ETSI. The goal recommendations.
The pace of adoption of agrees at least not until there tends to be a large the two systems is quite different With more than majority. This paper has from field trials. Kastell, S. Bug, A. Nazarov, and R. Jakoby, groups.

At present, there is no technical standard for Chinese train control systems. In order to ensure the safety and efficiency of train operation and to meet the requirements of modern technical development in railways, the concept of CTCS Chinese Train Control System was put forward in as the technical standard of Chinese train control systems by the Chinese Railway Ministry.
In the paper, CTCS is introduced. Based on the present situation of Chinese train control systems and their development requirements, both in technical and management aspects, the frame of CTCS is described.
Keywords: train control system, automation, Chinese railway, European railway, railway signaling. At present, Chinese Railways are facing the great challenge.
European railway traffic management system validation using UML/Petri nets modelling strategy
In the next twenty years, the Chinese Railway Network will be through the special periods of the 2 Advanced Train Control Systems quick development and extension. There are 71, kilometers of line in operation in Chinese railways.
With the development of the Chinese Economy, it is estimated that at least another 20, kilometers railway line is needed and will be constructed. In addition, the dedicated passenger lines and a high speed railway line will be constructed in the next few years. However, there are more than six kinds of signaling systems and they are not interoperable in the Chinese Railways due to the reasons of historical and technical development.
Up to now, there is no standard for railway signaling on Chinese Railways. The existing signaling systems can not be interoperable, and the direction of the new signaling systems is not clear. There is urgent requirement for the signaling standard of the Chinese Railway.
Under the standard, the future signaling systems and the existing signaling systems can be interoperable. The working program for CTCS has been started since last year. The event is the milestone in the signaling history of the Chinese railways. It will be playing a very important role in ensuring the Chinese railway network construction and perfection, train operation safety and efficiency, and guiding the future development of the Chinese railway signaling.
With development of European high speed railway network, apart from the different languages, there exists the strong barrier to cross-European borders since there are at least 15 different ATP systems in operation in Europe. Moreover, the ATP systems are incompatible and produced by their own suppliers.
In order to make the systems be compatible and break the monopolies, the idea of ETCS was put forward. The goals of ETCS can be described as the following seven aspects. The first one is interoperability which means that trains can be interoperable across borders and able to read signaling in different countries in Europe.
It also requires the operator interoperability and supplier interoperability. The second one is safety.
The third one is capacity. The fourth one is availability. Under the ETCS standardization, there is no needs for a train to be installed more kinds of on-board systems.
It means less equipment, fewer interfaces and less connection. Moreover, tele-diagnosis and maintenance help dramatically increase the reliability and maintenance of the system.
The fifth one is cost-effectiveness. ETCS means fewer products.
In this way, its manufacturing cost and maintenance cost could be decreased dramatically. A transition has five parts, namely Source state state affected by the transition , Event Trigger event whose reception makes the transition fireable, Fig. The transition can fire only if the condition evaluates to true, Fig. The proposed analysis is based on the combined use of Sequence diagrams and State machines because of the consistency between these two types of UML diagrams.
For instance, components of the Sequence Diagram are those of State machines, or are a proper subset. The translation of both State machines and Sequence diagrams to Petri nets is automatic. However, we are aware, that at this point, we cannot claim completeness for transforming all State Machine elements and constructs because we transform only elements used in our case study.
Indeed, there are some ambiguities for which we have made a specific choice, and also some characteristics that we have decided not to translate. So, the translation proposed here provides a formal semantics for a subset of the State machines and the same is true for Sequence diagrams.
The approach is based on a decomposition of UML State Machines into its basic elements, such as states, pseudostates, and transitions.
For each element, transformation rules from State Machines into Petri Net fragments are presented. Thereby, time constraints on transitions are taken into account. For Sequence diagrams, they are used to guide the connection of these Petri Net fragments, providing a single Petri net for the system under study. Indeed, each state is mapped into a place and each state transition becomes a transition in the Petri Net.
The resulting sub-models are combined using UML collaboration diagrams. In our study, the combination of our sub-models is done using the UML sequence diagram. Another approach for model transformation of UML diagrams is proposed by Merseguer [ 23 ] and Bernardi et al. In [ 11 ] an extension of UML models with probabilistic choice and stochastic timing is also proposed. A model transformation technique of UML diagram into a Stochastic Petri Net is established in order to measure performance by simulation or numerical analysis.
It is not possible for them to apply mathematical techniques directly on UML diagrams because it lacks a formal semantics.Only in Europe alone, there were This group of people had examined the basic principles more than 35 different platforms, and German Rail of GSM-R network planning.
GSM-R is a their advantages and disadvantages.
High Speed Railway Track Technical Options. Suitability Assessment Guide
Train integrity checking is carried out by on-board system. Track circuits no longer transmit information concerning train operation. With the development of the Chinese Economy, it is estimated that at least another 20, kilometers railway line is needed and will be constructed.
Rail traffic management is a key area for the medium-term optimisation of rail services. The control mode for ATP is the distance to go.
