A Development of the High-capacity Data Transmission System on Track Circuit Using Spread Spectrum Communication

Abstract

This paper describes the high-capacity data transmission system for advanced ATC (Automatic Train Control) System on track circuit. A conventional ATC system is very high safety, but this system has not realized the high-capacity data transmission because of the high return current noise. Therefore, we develop the high-capacity data transmission system using spread spectrum communication in consideration of the characteristic of track circuit. And we verified to be able to take about 2000 bps, with the result that we carried out computer simulations changed the transmission speed about this system. In addition, we studied about the method of a synchronous acquisition. As a result, we established a good method by giving the same data for a synchronous acquisition to some channels. We report this method with result of computer simulations.
