道岔区轨道电路叠加计轴设备方案的可行性研究

Feasibility Study on the Scheme of Track Circuit Superposition Axle-counting Equipment in Turnout Zone

针对道岔区轨道电路出现轨道电路红光带时,由于短时间内无法立即恢复而对行车组织造成影响的问题,提出在原有轨道电路基础上,叠加一套计轴设备作为后备的列车检测设备。此方案的轨道电路与计轴两套设备互为冗余,通过合理有效的叠加,可最大限度降低轨道电路故障对线路运营的影响,提升了列车运行效率。方案中对音频轨道电路上叠加计轴设备的可行性进行了分析,可为后续改造实施提供参考。

When the track circuit red light band occurs in turnout area,the operation organization will be affected because the track circuit cannot be restored immediately in a short time.Therefore,based on the original track circuit,a set of axle-counting equipment is stacked as the backup train detection equipment.In this scheme,the track circuit and axle counter are mutually redundant,through reasonable and effective superposition,it will minimize the impact of track circuit fault on line operation,improve train operational efficiency.In this paper,the feasibility of the superposition axle-counting equipment on the audio track circuit is analyzed to provide a theoretical basis for the subsequent transformation projects.
