Study on the Characteristics of the Transmitter Line for Data Transmitter between Vehicles for High speed train

고속전철의 열차간 데이터 전송을 위한 전송로의 특성에 관한 연구

Recently, the microprocessor with network function based control system instead of conventional microprocessor is widely used for industrial applications, and also these technologies are widely adopted for train control and monitoring in modem rapid transit system. The purpose of this paper is to propose a criteria for data transmission, which was designed and realized through Korea High Speed Train. Noise, distortion and attenuation are always present in data transmission system and strictly limit performance. This paper describes a method to calculate the propagation constant, attenuation constant, phase velocity and length of stub.
