摘　　要：我国已经开通运营的300km/h及以上的高速铁路,大多采用CTCS-3级列车控制系统,在日常检测中经常发现降级问题。通过对动态检测发现的降级问题进行分析,总结出无线超时导致降级的原因,积累故障处理方法、经验,不断提高故障处理业务水平、数据分析水平,确保CTCS-3级列控系统的稳定运行和安全性。Most of system. In routine the existing high speed railways over 300km/h in C dynamic inspection, it has been detected that the adopt CTCS-3 train control train control system frequently changed from CTCS-3 to CTCS-2. Through analyzing the problem, we concluded that wireless timeout can be one of the reasons. With the accumulation of experiences in handling the failures, the level of handling failures and analyzing the data has been improved, the operation safety and steadiness of the CTCS-3 train control system will be ensured.
