The invention relates to a track section division method based on an optimized operation interval. The track section division method comprises the following steps: step 1, acquiring railway line data, route data and train operation data; 2, calculating the most unfavorable braking distance length of the train on a line, obtaining the limit length of a track circuit, and calculating the train time interval; step 3, according to a calculation result and an empirical value in the step 2, preliminarily dividing a section length; step 4, according to the preliminarily divided sections, respectively calculating the time interval of each section, if the time interval of each section meets a preset value, completing division, otherwise, entering step 5; and step 5, finding out the time interval bottleneck of the section, and re-dividing the length of the section by changing the distance of the bottleneck section until all sections meet the requirement of the time interval. The result of the method is reliable, and the train passing efficiency can be improved through the division result.
本发明涉及一种基于优化运行间隔的轨道区段划分方法,包含以下步骤:步骤1、获取包括铁路线路数据、进路数据、列车运行数据;步骤2、计算列车在线路上最不利制动距离长度,获取轨道电路的极限长度,计算列车时间间隔;步骤3、按照步骤2的计算结果和经验值,初步划分区段长度;步骤4、根据初步划分的区段,分别计算各个区段时间间隔,若区段时间间隔满足预设值则划分完成,否则,进入步骤5;步骤5、找出区段时间间隔瓶颈,通过改变瓶颈区段的距离,重新划分区段长度直到满足所有区段均满足时间间隔的要求。本方法的结果可靠,划分结果可以提升列车通行效率。
