普速铁路自动闭塞区间信号点类型构建研究

针对普速铁路自动闭塞区间信号点布置多样、区间信号点最高编码码序提升、区间信号点类型种类多且名称复杂混乱的现状,基于区间信号点的编码码序,以及其与车站的相对位置关系,提出区间信号点类型的构建方法,在此基础上构建在普速客货列车共线运行、重载铁路、铁路枢纽、既有线提速等不同运营场景下,适用于普速铁路自动闭塞区间不同最高编码码序、不同区间信号点布置情况的所有区间信号点类型,并将其应用于普速铁路自动闭塞区间的信号工程设计中。实际的工程应用实例表明,构建的区间信号点类型名称简单、含义清晰,具有通用性和可拓展性,适用于普速铁路自动闭塞区间信号点的所有布置情况,能在普速铁路所有的自动闭塞区间工程中直接应用。

Research on Construction of Signal Types in Conventional Railway Automatic Blocking Section

In view of the multiplicity of section signal layouts, the upgrade of the highest code sequence, the variety and complexity of the section signal types with confused names in conventional railway automatic blocking section, a construction method for section signal types is proposed based on code sequence of track circuits, and the relative position between section signal and station is presented. Then, all the section signal types suitable for different highest code sequence and section signal layouts in conventional railway automatic blocking section are established and applied to signal engineering design under different operating scenarios such as shared operation of conventional passenger train and conventional freight train, heavy haul railway, railway hub, and speed-up of existing lines. The actual engineering applications show that the section signal types presented by this paper are named simply and defined clearly with universality and extensibility, and are suitable for all of the section signal layouts in conventional railway automatic blocking section, and could be applied directly to all constructions of automatic blocking sections in conventional railway.
