摘要:

为预防铁路安全事件的发生,设计ZPW-2000轨道电路故障诊断系统的总体结构,明确4大组成部分,包括数据预处理、数据分析、数据服务及数据应用。首先,通过改进的旋转门转换(SDT)算法对轨道电路电气特性数据进行数据压缩;其次,分段线性拟合轨道电路不同状态下的模拟量数据,计算得到特征值;最后,通过密度聚类的特征提取方法诊断轨道电路故障,并通过系统验证9种常见轨道电路故障。结果表明:改进的SDT算法可以有效对轨道电路电气特性数据进行数据压缩,压缩后的数据经过分段拟合后可以有效提取特征值,应用密度聚类算法可以生成诊断模型,提升轨道电路故障诊断的准确性,从而提高信号设备维护效率和维护水平。

Abstract:

In order to prevent railway accidents, overall structure of ZPW-2000 track circuit fault diagnosis system was designed, and four major components were clarified, including data pre-processing, data analysis, data service and data application. Firstly, electrical characteristics data of track circuits were compressed by improved revolving gate algorithm. Then, piecewise linear fitting was carried out for analog data in different states of the circuits, and eigenvalues were calculated. Finally, circuit faults were diagnosed by feature extraction method of density clustering, and 9 common ones were identified. The results show that the improved SDT can effectively compress electrical characteristics data of track circuits, eigenvalues of compressed data can be effectively extracted after segmental fitting, and furthermore, density clustering algorithm can be used to generate an effective diagnostic model. Improving fault diagnosis accuracy can help increase maintenance efficiency and capability of signal equipment.
