TCN is the most suitable international standard communication network for distributed control systems that is adopted for high-speed of vehicle, safety and flexibility. TCN is the network exclusively for the high-speed train and electrical trains. This TCN satisfies the network standards. The network standards are real time communication, fault tolerance design, integrated data system, resistance of environment, automated recognition for modification of vehicle formation and maintenance. The purpose of this research is applying the development of WTB analyzer which is part of communication network system TCN, to check the communication of high-speed trains and electrical trains.

  • The On Board Computer System (ORCS) used for rolling stocks is one of the core equipments in trains, which deals with collecting real-time data of a train to display and record the train's statuses, control the train, and support the driver and maintenance function. Resides, due to high reliability and high speed communication required lately for various electronics including signal1ing devices, train protection system, and multimedia, the necessity of a more robust train communication network is on the lise. This study aims at understanding the technological trend of the current train communication network in order to rapidly cope with the tendency above and providing fundamental data for designing a more advanced communication network for high-speed trains hereafter.

Results of some simulation tests are also reported. This paper presents a Train Communication Network simulator(TCNS) that can be used to evaluate the performance of TCN. TCN was accepted as the standard of the protocol for the communication network in trains. TCN of fieldbus was adopted as international standardization IEC 61375 in 1999. It has been operating on G7 train in korea. This paper developed TCNS(Train Communication Network simulator) as a simulator for performance evaluation. We can verify TCNS for preventing many kinds of occurring problems between the devices in data-communication. This study was developed TCNS as a simulator for the performance evaluation. We analyzed correlation between token, transmission data per paket and transmission speed of bus, through the TCNS, also analyzed result according to error rate of TCN.

  • This paper evaluates the real-time performance of the Train Communication Network (TCN) that consists of WTB and MVB. A run-time scheduling algorithm for the hard-real time communication was proposed and its performance was evaluated. Also, a new addressing method and the adaptive tree algorithm were suggested to enhance performance. The overall performance was evaluated by computer simulation using Arena.

  • Train control and monitoring system for the railway train requires a reliable real-time communication network. The system have various functions, diagnostics, passenger informations, and fault-tolerant controls. For this system, an international standard called TCN(Train Communication Network) is proposed by IEC and the train industries. The TCN is composed of two layers, wire train bus(WTB) and multifunction vehicle bus(MVB). This paper evaluates the performance of the proposed WTB and modified WTB. And computer simulations are performed. The evaluated results can be used for the fault tolerant network in the railway train system.

  • This paper reports on a study to increase the flexibility of previous TMDS(Train Monitoring and Diagnosis System) network communication in case of both multiple units and variable train sets. The previous TMDS network configuration has been applied using various field-BUS by the TMDS manufacturers using their own intrinsic method. But recently, there has been a demand for flexible train formations such as multiple units and variable train set formations, hence the TMDS had to be adapted to offer flexible network communication technology capability. Therefore, Hyundai-Rotem needed its intrinsic method of network configuration, and develop a network configuration method applicable to both multiple units and variable train set formations. The TMDS was integrated into the Irish Rail new Diesel Multiple Units from an early stage of the project and subsequently fully tested on a finished train.

  • TCN(Train Communication Network) adopts the master/slave protocol to implement real-time communication. In this network, a fault on the master node, cased by either hardware or software failure, makes the entire communication impossible over TCN. To reduce fault detection and recovery time, this paper propose the contention based mastership transfer algorithm. Slave nodes detect the fault of master node and search next master node using the proposed algorithm. This paper also shows the implementation results of a SoC-based Fault-Tolerant MVB Controller(FT-MVBC) which includes the fault-detect-logic as well as the MVB network logic to verify this algorithm.
