REVISIÓN SISTEMÁTICA A LA LITERATURA PARA DETERMINAR LOS ENFOQUES DE LA INVESTIGACIÓN EN VERIFICACIÓN FORMAL DEL SOFTWARE ** Artículo en estado de edición para envío a publicación (Julio 2011)

s: Based on the field bus technology, the computer network communication technology, embedded control system, the rapid development of technology and fault diagnosis technology, train communication network system based on formal method and simulation method are reviewed. For the application as a starting point, makes a research from the formal modeling, train communication network node system, dynamic property verification etc., summarizes the problems existing in this field, and the node system and topology communication network on the modern high speed train is optimized, provides system level reference for the design of train communication network and node system.

Optimization Design of Topology Structure of High Speed Train Communication Network Node

This paper provides a novel solution to available train network by analyzing and comparing the present development and application situation about kinds of technologies of train network. C-MBUS is proposed for train network and fire warning system. This paper designs a system frame of train intelligent fire warning terminal based on C-MBUS. In the design, using C-MBUS for this project to connect train intelligent fire warning terminal and the smoke fire detector on the train helps users control them easily, security and remotely. What is more, C-MBUS is low voltage and the data transfer rate is high for meaningful data communication.

Design of train intelligent fire warning system based on C-MBUS

In order to meet the information transmission requirements of large capacity,high speed and hard real-time in the future,switched ethernet was introduced to the train communication network (TCN).Messages of different priorities was investigated,and established the TCN transmission process model with determined and stochastic Petri nets (DSPN) in accordance to its communication scheduling mechanism.The influences of different switch scheduling algorithms to the delay were compared,and the relationships between throughput and message number,throughout and generating cy-cle were respectively investigated.The experimental results show that the priority scheduling algorithm can reduce the delay of real-time data under the condition of sacrificing non real-time data's delay.It also verify the throughput of TCN based on switched ethernet is much higher than that of the existing TCN,which can provide theoretical basis for the de-sign and optimization in the future.

Modeling and Performance Analysis of Train Communication Network Based on Switched Ethernet

This paper presents a formal verification methodology of the Coloured Petri Net model of MVB-TCN device using symbolic model checking technique. The methodology proposed addresses the model checking of critical properties of MVB-TCN device including safety, liveness and fairness properties which are expressed in computation tree logics. As a confirmation of its validity, the methodology described in this paper has been successfully applied to modeling and formal verification of Line Redundancy Control unit of MVB-TCN device.
