摘要
针对站内25Hz相敏轨道电路分路不良问题,通过系统分析,建立轨道电路预警模型,采用模糊模式识别方法实现轨道电路调整电压、现场温湿度以及故障次数的预警,并详细论述了轨道电路模糊模式识别模型的建立,同时给出了预警系统的实现方案;模拟实验及仿真结果表明,模糊模式识别在轨道电路分路不良预警中具有较高的准确性和应用价值,对解决轨道电路分路不良问题提供了有效的技术支持,为轨道电路日常维护和故障的及时发现处理创造了条件。
Aiming at the problem of poor shunting in 25Hz phase detecting track circuit, established the track circuit pre--warning model through systematic analysis, adopted fuzzy pattern recognition to realize the pre--warning of track circuit voltage, temperature humidity and failure number, and discussed the establishment of the track circuit fuzzy pattern recognition model in detail, meanwhile, gave the realization scheme of pre--warning system. The simulative experiment result shows that the {uzzy pattern recognition method has high accuracy and application value, and it will create conditions for daily maintenance and track circuit fault detection in time.
