摘　　要：针对CTCS2-200K型列控车载设备在渡线岔区偶发性掉码问题,首先通过对比分析同一地点不同车次列车轨道电路码接收情况,发现掉码与列车速度有关,也与上下行载频切换命令的配置参数有关。然后减小该参数后进行现场试验验证,结果表明:列车以不同速度进站场景下,再未发生过掉码问题。最后提出相关思考,为处理其他类似问题提供参考。Aiming at the problem of occasional code missing of CTCS2-200K ATP on-board equipment in the crossover bifurcation area,firstly,by comparing and analyzing the track circuit code received from different trains in the same place,it is found that the code missing is related to the speed of the train,and also to the configuration parameters of the uplink and downlink carrier frequency switching commands.Then,after reducing the parameter for field test verification,and the results show that the code missing does not occur again under the operation scenarios of train entering into station with different speeds.Finally,some relevant thoughts are put forward,which can be referenced for dealing with other similar issues.
