A high-speed rail dispatching method and system under abnormal weather

Abstract

The invention provides a method and system for scheduling high-speed rails in unusual weathers. The method comprises the steps that execution schedules corresponding to different speed limit values are stored in advance; moreover, in the running process of high-speed rail trains, the current moment and the longitude and latitude information of the high-speed rail trains at the current moment are related to the execution schedules corresponding to all the speed limit values, so that the execution schedules corresponding to all the speed limit values are corrected in real time; the execution schedules corresponding to all the limit values are all matched with the current running states of the high-speed rail trains, once the speed limit values change due to weather changes, an execution schedule corresponding to a new speed limit value can be executed through switching, real-time switching is achieved, and the high-speed rail trains run instantly according to the execution schedule corresponding to the new speed limit value. By means of the method and system, it is guaranteed that the high-speed rail trains can really run according to the preset schedules in unusual weathers with the accuracy reaching a second level.

Description

technical field [0001] The invention relates to the field of high-speed rail train dispatching, in particular to a high-speed rail dispatching method and system under abnormal weather. Background technique [0002] With the rapid development of society, the exchanges between cities are becoming more and more frequent. In order to shorten the travel time between cities, my country has carried out large-scale high-speed railway construction and put it into operation. How to ensure the safe and punctual operation of high-speed railways has aroused people's height focus on. [0003] At present, the train operation dispatching system of high-speed railway is dispatched by adopting the principle of automatic block partition of traditional railway. The so-called block partition is to use the track circuit to separate each section of track, and each section of track forms a block partition. Install a signal light or a virtual signal light at the starting point of each block zone. W...

Problems solved by technology

Under normal circumstances, the difference between the actual arrival time of the train and the time stipulated in the running timetable is tens of seconds or even a few minutes, and it is impossible to arrive at each stop accurate to the second, and it is impossible to achieve the accuracy to the second during the operation. Arrive at the specified point

[0005] Moreover, in the prior art, a timetable is used for high-speed rail scheduling under normal circumstances. If there is a sudden change in the weather, such as: when there is sudden rain and snow, the track is slippery; or there is a sudden foggy weather , leading to decreased visibility, it is necessary to adjust the running speed of the high-speed train in real time. However, after the current high-speed train adjusts its running speed, it cannot run according to the new timetable to the second, and the running process of the high-speed train can only rely on driving. Driving based on the driver's experience, the time to reach each location point can only be random, so accidents are prone to occur in busy areas
