我段自开通站内移频电码化以来 ,出现了不少掉码、串码或错码问题 ,为此组织了大量的攻关活动 ,现将故障成因及解决方法介绍如下。1　电路设计不完善造成股道内掉码大江口站自轨道电路叠加移频开通以来 ,机务部门多次反映上行 4道掉码、下行 3道接码点距离出发信号机太近 ,两股 I since the opening paragraph within the station frequency shift code, there have been many out of code, string code or wrong code, this organized a large number of research activities, now the cause of the malfunction and solutions are described below. A circuit design imperfect cause the stock channel out of code Since the track superposition of the Ogikuchi railway track frequency shift since the opening, the maintenance department repeatedly reflected the uplink 4 out of code, the downlink 3 code points too far from the departure signal, two shares
