Abstract

This paper considers the carrier frequency selection method for continuous cab signaling using a set of criteria for minimum inductive-rail line attenuation and maximum noise immunity. The mathematical expressions used for evaluation of signal attenuation in rail, inductive, and inductive-rail lines are given, and the corresponding conditions and assumptions are indicated. To determine the locomotive receiver noise immunity, the method of simulating its operation was used when receiving an additive mixture of an amplitude-shift keyed signal and impulse noise. It is shown that, under the indicated conditions and criteria, the optimal frequency values are 325 and 375 Hz.

关于连续驾驶室信令的载波频率选择方法

摘要

本文考虑了使用一系列最小感应铁路线衰减和最大抗扰度的标准来进行连续驾驶室信号传输的载频选择方法。给出了用于评估铁路线,感应线和感应式铁路线信号衰减的数学表达式,并指出了相应的条件和假设。为了确定机车接收机的抗扰度,当接收到幅度移动键控信号和脉冲噪声的混合信号时,将使用模拟其运行的方法。结果表明,在指定的条件和标准下,最佳频率值为325和375 Hz。
