열차간 데이터 전송을 위한 전송로의 접지 특성에 관한 연구
Study on the Earth Characteristics of the Transmitter Line for the Data Transmitter between Vehicles.
초록
Recently, the microprocessor with network function based-controlled systems instead of conventional microprocessors is widely used to industrial applications, and also those technologies are widely adopted for train control and monitoring in modern rapid transit systems such as railway vehicles. The purpose of this paper is to propose a high quality data transmission line of railway vehicle system controlled by a microprocessor, which was designed and realized through SMG 7&8 and ISA project. 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.
