Description

一种列车定位方法、装置、终端设备以及存储介质
本申请要求在2022年01月26日提交中国专利局,申请号为202210094132.X的中国专利申请的优先权,该申请的全部内容通过引用结合在本申请中。
技术领域
本申请实施例涉及轨道交通领域,尤其涉及一种列车定位方法、装置、终端设备以及存储介质。
背景技术
目前,随着科学技术的进步以及工程技术的发展,人们提出了多种列车定位技术,如轨道电路、里程计、查询/应答器、测速仪、卫星系统、无线通信以及感应回线等。但是现有对列车进行定位的技术,存在着以下缺点:
(1)基于轨道电路的列车定位的缺点是定位精度取决于轨道电路的长度,定位不够精确,无法构成移动闭塞。
(2)基于查询/应答器的列车定位是轨道交通上运用最为广泛的一种方式,但是其缺点是只能给出点式定位信息,存在设置间距和投资规模之间的矛盾,目前一般采用混合定位法,即用基于测速的列车定位,以查询/应答器纠正因轮径变化、打滑或空转产生的累计误差。
(3)基于无线通信的列车定位技术是一种新的定位技术,是基于先进的通信技术以及计算机技术的移动闭塞定位方法。通过在列车上和轨道旁设置无线电设备,利用先进的无线通信和计算机信息处理技术,实现列车的实时定位。采用该方法的优点是定位比较精确,但缺点是需要在沿线设置专用扩频基站,投资成本较高。
(4)基于感应回线的列车定位是当列车经过每个电缆交叉点时,车载设备检测到回线内信号的极性变化,并对极性变化的次数进行计数,从而确定列车经过的距离,达到定位目的。此定位方法同样受到交叉区长度的影响,且如果交叉区比较窄,位置脉冲漏计的可能性很大,定位的准确度较低。
综上所述,如何在低成本的条件下实现对列车的位置进行实时定位,成为了目前亟需解决的一个技术问题。

如图4所示,图4为本发明实施例提供的一种列车定位方法的流程图,包括以下步骤:
步骤301、获取每条线路的线路信息,线路信息包括有线路上下行两个方向的车站;
步骤302、获取当前各个车站的各个站台的列车到站信息,列车到站信息包括有各个站台即将到站的列车信息;
步骤303、根据线路信息以及列车到站信息,得到每条线路的在途列车信息,在途列车信息包括有每条线路的上下行两个方向的每辆列车即将到站的站台以及到站时间;
步骤304、根据在途列车信息,确定每条线路上每一辆列车的位置信息。
步骤305、根据每条线路上每一辆列车的位置信息,实时对预先设置的列车运行图进行调整。
在一个实施例中,在得到每条线路上每一辆列车的位置信息后,将每条线路中每个列车 的位置信息和预先设置的列车运行图中每辆列车的预估运行位置进行比较,若偏差大于预设值,则对该线路的列车运行表进行实时调整,在调整过程中可以考虑每个车站的列车的延迟原因,例如相邻两辆列车达到的时间间隔内进站人数大于列车运载量时,为高峰延迟;若进站人数小于运载量,则可能时出现突发状况导致延迟,根据不同的延迟原因对列车运行图进行调整,从而提高列车的运行效率和乘客输送能力。
