高速铁路轨道电路动态检测数据分析

Data Analysis of Track Circuit Dynamic Test for High Speed Railway

摘 要:伴随着铁路的快速发展,通信信号技术日新月异,轨道电路作为信号系统的主要设备之一,其作用依然重要。高速铁路开通以来,轨道电路作为信号轨旁设备,综合检测列车一般每月进行2次日常检测,积累了大量检测数据。在此基础上,选取特定区段固定时间的轨道电路检测数据,使用数理统计方法,对轨道电路传输特性参数进行分析,提出可能的发展趋势,为养护维修提供支持,同时为深入开展数据分析打下基础。

With the rapid development of railway, the technology of communication and signaling advances with each passing day. As one of the main equipment for signaling system, track circuit still plays an important role. Since the open of high speed railway, the comprehensive test train has generally made the daily test for twice in each month. And the track circuit has accumulated a lot of test data as the trackside equipment of signaling. On that background, this thesis selects the track circuit inspection data in specified section for fixed time, analyzing the transmission characteristic parameters of track circuit with mathematical statistics. Moreover, it proposes the possible developing trend to provide the support for maintenance and repair. Meanwhile, this thesis will lay the foundation for carrying out the further data analysis.
