Crosstalk Reduction in Balise and Infill Loops in Automatic Train Control

摘要

The aim of this paper is to analyze the range of crosstalk problems encountered with the major trackside equipments, the Balise and the Loops, used in Automatic Train Control for metro rails. Crosstalk impedes the efficient and safe data transmission between the tracks and the train. The installation requirements for the balises and the infill loops are elaborated in this paper. At present, coaxial leaky cables are employed for the infill loops but they do have some limitations under certain situations. A comparative study on the existing methods of crosstalk reduction is given here and an optimal solution based on the problem is proposed.
