摘 要: | 计轴系统是一种重要的轨道交通信号设备,广泛应用于铁路、城市轨道交通领域。以无锡地铁2号线计轴系统故障为例,分析了在2号线运营环境下的电磁干扰对计轴轨旁设备产生"脉冲不计数"故障(WPOZ)的原因,提出了设置检测点至"高功率"模式的解决方案。测试结果表明,所推荐的检测点设置方法可大幅度降低受扰机率。

Analysis and Solution of Special Axel Counter System Failures |

Abstract: | Axle counter system is an important railway signa-ling equipment,widely used in railway and urban rail transit. By analyzing the failures of Wuxi Metro Line 2 axle counter system on Wuxi Metro Line 2,the reasons of electromagnetic interference in the operating environment of Wuxi metro is e-laborated,which generates the axle counter trackside equip-ment WPOZ faults,a solution of setting the monitoring points in “High Power”mode is proposed,and the testing result shows this fine-tune settings of axle counter trackside equip-ment can greatly reduce the disturbed chances. |
