s14: and determining the running direction of the train according to the information whether the train regresses and the direction of the train.
Specifically, referring to fig. 2, fig. 2 is a schematic diagram of a running state of a train on a running line, a plurality of virtual reference points are set at preset positions of the whole line of the running line of the train, position information of the virtual reference points, such as a, B, C, and the like, is stored in a ground system, a master control locomotive and each locomotive in advance, the master control locomotive and each locomotive send position information of the master control locomotive and each locomotive relative to the virtual reference points to the ground system, and two virtual reference points at which the master control locomotive or the locomotive is located at two ends of the master control locomotive and has the closest distance to the master control locomotive or the locomotive and the distance between the two virtual reference points are obtained from the position information. For example, the length between the virtual reference point a and the virtual reference point B is 100 meters, the location of the locomotive 1 at the distance a is 48 meters, and the distance B is 52 meters, the location information of the locomotive 1 may include the identification number of the virtual reference point a and the identification number of the virtual reference point B, and the distance value between the locomotive 1 and the virtual reference points a and B.
The master locomotive is generally located at both ends of a train and serves as the head of the train, so that the position information of the head of the train can be known by obtaining the position information of the master locomotive, and each locomotive can be located at any position in the train. In order to obtain the direction and the running direction of the train, the ground system determines the master locomotive first according to the information whether the master locomotive of the train and the information whether the master locomotive are the master locomotive sent by each locomotive, and after the master locomotive is determined, determines the direction in which each locomotive points to the master locomotive as the direction of the train according to the position information of the master locomotive and the information of the master locomotive sent by each locomotive, as shown in fig. 2, for example, if the ground system has determined that the locomotive 1 is the master locomotive, the direction of the train is the direction in which the locomotive 2 faces the locomotive 1, that is, the direction of the train is the direction from the virtual reference point B to the virtual reference point a. And the ground system obtains the running direction of the train according to the information of whether the train regresses and the determined direction of the train, which are sent by the master locomotive, namely if the train runs backwards, the running direction of the train is the reverse direction of the train, and if the train does not run backwards, the running direction of the train is the same as the direction of the train.
Therefore, according to the method and the device, the plurality of virtual reference points are arranged at the preset position of the train running line, the position of the locomotive of the train is determined according to the position information, relative to the virtual reference points, of the master control locomotive and the position information, sent by each locomotive, of the master control locomotive, the orientation and the running direction of the train are obtained according to other information sent by the master control locomotive, extra equipment does not need to be added on the rail line, and the construction cost is reduced.
On the basis of the above-described embodiment:

Therefore, after the master control locomotive is determined, the running speed of the train sent by the master control locomotive can be obtained, whether the running speed exceeds a preset speed threshold value or not is judged, and the method for judging the direction and the running direction of the train is adopted only when the running speed of the train is low, so that the condition that the direction and the running direction of the train are judged wrongly due to communication delay is avoided to a certain extent.

By adopting the method, when the running speed of the train is high, even if communication delay occurs, the positions of the same locomotive in the two times before and after can not be dislocated, the running direction of the train can be determined according to the position change of the same locomotive in the two times before and after, and the orientation of the train can be determined according to the running direction, so that the method has accurate result and high reliability.
As a preferred embodiment, the speed threshold is 5 km/h.
In this embodiment, the threshold for distinguishing the speed of the train is set to 5 km/h. Here, the threshold value should be specifically determined according to the level of the communication delay, the level of the communication delay includes various influence factors such as the time of the communication delay, the packet loss rate, etc., the threshold value is set to 5km/h in the present application, which can satisfy most levels of the communication delay, of course, the threshold value may also be dynamically changed according to the level of the communication delay, and the present application is not limited thereto.
