摘要

为了改进提高音频轨道电路抗扰性的方法，在剔除有用信号脉冲间隔干扰的基础上，分析了音频轨道电路传输路径中信号传输时间随其工作参数(信号电流频率、轨长、绝缘电阻和环境温度)的波动规律。为此，建立了音频轨道圆工作的仿真模型。在仿真结果的基础上，建立了测量特性值的关系数据库。利用智能分析方法，确定了影响信号在音频轨道电路传输路径中传递时间的主要因素是信号电流的频率。确定了音频轨道电路工作参数与信号传输时间的主要依赖关系。所得结果有助于提高音频轨道电路工作的抗噪声能力，因为它可以更精确地调整有用信号脉冲之间的干扰截止间隔。

SIMULATION AND INTELLECTUAL ANALYSIS OF AUDIO FREQUENCY TRACK CIRCUIT PARAMETERS

To improve the method of increasing the noise immunity of a audio frequency track circuit, based on cutting out interference in the intervals between useful signal pulses, an analysis was made of fluctuations in the signal transit time in the transmission path of a audio frequency track circuit depending on its operation parameters: signal current frequency, rail line length, insulation resistance and ambient temperature. For this, a simulation model of the operation of a audio frequency track circle has been developed. Based on the simulation results, a relational database was created with the values of measurement characteristics. With the use of intellectual analysis methods it was determined that the main factor affecting the signal transit time in the transmission path of the audio frequency track circuit is the frequency of the signal current. The main dependences of the operation parameters of the audio frequency track circuit and the signal transit time are determined. The obtained results help to increase the noise immunity of the operation of audio frequency track circuits due to a more precise adjustment of the interference cut-off interval between the useful signal pulses.
