Problems solved by technology
In the current technology, the position message sent by the on-board controller of the train only contains position and direction information. Based on these two information, it is necessary to compare the line link relationship and the position of the train at adjacent times to determine whether the train switches the head. The time / space overhead is large, so Causes problems such as long judgment time and low accuracy, so how to quickly and accurately judge whether the train head is switched has become a technical problem that needs to be solved

Embodiment 1
[0035] Such as figure 2 As shown, a method for automatically judging the train head switching based on the equivalent direction of the line map includes the following steps:
[0036] Step A: Construct the equivalent direction of the static line map;
[0037] Step B: Calculate the equivalent direction of the train head;
[0038] Step C: calculating the train number (Cab ID);
[0039] Step D: Judging whether the train switches the head.
[0040] 1. Construct the equivalent direction of the static line map, specifically:
[0041] Set the equivalent direction of the track section, and build a static branch, so that the equivalent direction of the track section accessible by the train running line is the same.
[0042] 2. Calculate the equivalent direction of the train head
[0043] a) The on-board controller of the train sends a position message to the regional controller, describing the position and direction information of the train, which can be obtained directly from the...
Embodiment 2
[0051] Such as image 3 As shown, the present invention is based on a line map equivalent direction automatic head switch judging device, including:
[0052] Equivalent direction building module 1, used to construct static route map equivalent directions;
[0053] The equivalent direction calculation module 2 is used to calculate the equivalent direction of the train head;
[0054] The locomotive number calculation module 3 is used to calculate the train locomotive number Cab ID;
[0055] The judging module 4 is used for automatically judging whether the train switches the locomotive.
[0056] The equivalent direction construction module 1, the equivalent direction calculation module 2, the vehicle number calculation module 3 and the judgment module 4 are connected in sequence.

Abstract
The invention relates to a vehicle head switching automatic judgment method and device based on a line map equivalence direction. The method comprises the following steps: step A, constructing a static line map equivalence direction; b, calculating an equivalent direction of a train head; c, calculating a train head number Cab ID; and D, automatically judging whether the train head of the train is switched or not. Compared with the prior art, the method has the advantages of less required information, high judgment speed and the like.
Description
technical field [0001] The invention relates to train signal control technology, in particular to a method and device for automatically judging locomotive switching based on the equivalent direction of a line map. Background technique [0002] In recent years, with the rapid development of rail transit in major cities in my country, more and more attention has been paid to the high-speed and reliability of train operation. It is of great significance to quickly and accurately determine whether the front of the train has switched during the running of the train. In the current technology, the position message sent by the on-board controller of the train only contains position and direction information. Based on these two information, it is necessary to compare the line link relationship and the position of the train at adjacent times to determine whether the train switches the head. The time / space overhead is large, so Causes problems such as long judgment time and low accura...
