摘　　要：在单线半自动闭塞铁路改造为双线自动闭塞区段铁路施工过渡期间,为减少施工过渡,降低施工成本,存在将单线铁路半自动闭塞改造为单线铁路正向按自动闭塞行车,反方向按照自动站间闭塞方式行车,需频繁进行区间改方运行,若车站存在坡道延续进路,易由于四线制方向电路固有问题造成改方失败,干扰正常运输。就四线制方向电路结合坡道延续电路进行分析研究,对此类情况下的改方电路设计和延续进路解锁表示信息提出改进建议和实现方案,供信号工作者参考。During the construction transition period from semi-automatic block of single track to automatic block of double track,the interlocking software replacement is required because one track has not been laid and the station turnout insertion and paving are carried out in advance,etc.In order to reduce the construction transition and the construction cost,the semi-automatic block mode of the single-track railway is transformed into the automatic block mode of the single-track railway in the forward direction and the automatic inter-station block mode in the reverse direction,that is to say,the section track circuit carries out operations for changing the running direction frequently.At this moment,if there is a down grade successive route and so on,it is easy to cause the direction change failed because of the inherent problems of the four-wire directional circuit,which leads to the station attendant mistook the equipment for fault and further causes the equipment fault with long time delay and greatly interferes with normal transportation.This paper analyzes the equipment fault cases and puts forward improvement suggestions for reference of signaling staff.
