摘要
列车间隔时间是影响铁路通过能力的重要参数。我国普速铁路已推广应用LKJ-15型列控系统,具备了按连续速度控制模式行车的条件。对普速铁路列控系统的发展进行梳理,指出按连续速度控车计算列车间隔时间的先进性。然后对固定间隔距离的计算方法和连续速度控车的计算方法进行对比分析。其后,选取具有代表性的间隔时间类型,并提出间隔时间理论计算公式。最后,选取合理参数对间隔时间进行检算。结果表明,在自动闭塞区段,连续速度控车法的检算结果明显小于固定间隔距离法;在单线区段则固定间隔距离法更具优势。按连续速度控车法计算列车间隔时间,可实现货物列车按6 min追踪、旅客列车按5 min追踪的要求,可对通过能力提升起到积极作用。
Train headway is an important parameter affecting the passing capacity of conventional railway.China has popularized LKJ-15 in conventional railway,which has the conditions for operating according to the continuous speed control mode.Firstly,this paper reviewed the development of the train control system in conventional railway and pointed out the progressiveness of calculating train headway according to the continuous speed control.Then,the calculation methods based on fixed interval distance and continuous speed control were studied for rationality analysis.Additionally,the representative train headway types were selected,and the theoretical calculation formula of train headway was put forward.Finally,reasonable parameters were selected to check the train headway.The results show that in the automatic block sections,the continuous speed control method yields better checking results than the fixed interval distance method,while in the single track sections,the fixed interval distance method has more advantages.Calculating the train headway according to the continuous speed control method can meet the requirements of freight train tracking according to six minutes and passenger train tracking according to five minutes,which can play a positive role in improving the passing capacity.
