Abstract

Abstract: In the construction of signal equipment for Handan-Jinan Railway expansion and reconstruction, the distance is not accurate due to that the locomotive directly passed over the signal without distance correction by LKJ-2000. In order to find out the reason, this paper analyzes the principle, processing mode and procedure of distance correction of LKJ-2000 when locomotive passing over signal, which can provide reference and analysis method for the distance correction failure of LKJ when passing over signal.

Key words: LKJ, passing over signal without distance correction, track signal, carrier frequency leakage

摘要： 在邯济线扩能改造信号设备施工过程中，LKJ-2000型列车运行监控记录装置过机不校，导致数据距离不准的情况。研究LKJ-2000型列车运行监控记录装置过机校正原理，分析过机校正的处理方式和过程，并查找出造成邯济线过机不校的原因，从而对分析LKJ过机校正不良提供参考和思路。

关键词: 列车运行监控记录装置, 过机不校, 轨道信号, 载频泄漏
