In Korea, TCN has applied to the Korean High-speed Train (HSR350X) through G7 High-speed Train development project. 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.

TCN define that WTB's network speed is 1Mbps. However, Network speed need to be improved as number of data is increased and near future train's requirement require more high speed between trains. therefore we studied implementation of 2 Mbps speed on WTB. we also made new communication board for more stable test environment. they have dual communication channel and switch over logic. Software has function to set clock value for 2 Mbps. we also implement logic for Manchester Encoder/Decoder logic that is required by WTB specification. Existing WTB network speed is 1Mbps and Data Period is 25㎳ and Basic period is 2 ㎳. In this study, we test WTB network speed is 2Mbps and Data Period is 12㎳ and Basic period is 1 ㎳. This study is about implementation how we can improve WTB network speed. Accordingly, I suppose that this thesis will be utilized to implement and test more stable and high speed communication in high speed train

본 논문에서는 현재 MAN으로서 표준화가 진행 중인 DQDB와 FDDI에서 제공되는 우선순위 체계의 효율성을 시뮬레이션을 통하여 비교하였다. 시뮬레이션 언어로는 SMPL을 사용하였으며 부하량을 변화시키면서 데이타 전송 처리율과 데이타의 평균 전송 지연 시간을 구하여 비교하였는데 DQDB와 FDDI 모두 만족스러운 우선순위 전송 서비스를 제공하였다. 데이타 전송 처리율에서 DQDB가 FDDI에 비하여 보다 유리한 우선순위 체계를 가지고 있으며 평균 전송 지연 시간 측면에서는 높은 우선 순위의 데이타 전송에서는 DQDB가 FDDI보다 우수하나 낮은 우선순위의 데이타를 전송하는데 있어서는 FDDI가 DQDB보다 약간 더 유리한 것을 알 수 있었다.

The bogie hunting sensor detects accelerations of a bogie. It transmits those accelerations using frequency modulated signal to the TCMS(Train Control and Management System) electronics for functional processing. TCMS decide undesirable bogie hunting and high speed instability with frequency modulated signal. The bogie hunting sensor is essential component for safety driving of high speed train. The bogie hunting sensor's quality inspection before sensor is installed on bogie is very important. Therefore it is required equipment for exact inspection of train bogie hunting sensor. This study is about development of Bogie Hunting sensor's inspection equipment that we can improve Bogie Hunting sensor's quality. Accordingly, I suppose that this thesis will be utilized to improve the bogie hunting sensor's quality thru exact inspection.

There are increasing customer’s needs for safe operation and comfort of trains for the passengers as trains are getting fast and developed with advanced components. To meet the needs we developed the system which is able to prevent possible risk elements by transverse vibrations during the train operation. System records the amplitude data of trains vibration and location data from GPS antenna in real time. The system is composed of 5 different functioning modules as following GCPU, GGWD, GIFD, GAID and GPSD. GAID module is detecting amplitude value of vibration which is sensed by bogie hunting sensor’s. GFID gets location information where vibration data is detected with GPS Antenna. Once those data is prepared, GCPU testify it’s amplitude and decides whether it send those data. When it sends those recorded data, those data are sent to control unit by MVB communication. we expect that this information will help operation and maintenance engineers improve the safety train services. This paper explains train transverse Vibrations data recording system and its major functions which can measure the amplitude of trains’s data during the operation and introduces the configuration for the system setup.

A few years ago, The trains had little control equipment so the trains had little data transmission between control equipment. Recently, there is a lot of control equipment in a train as traction control, air conditioners and even internet access. for this reason, vehicle network must allow for the big amount of transmission data and must ensure the high reliability. In this paper we present monitering system for verify high reliability of data transmission of MVB of TCN which is an international standard of IEC 61375.
