Problems solved by technology

[0003] There are many situations where trains need to be screened, for example, when the on-board ATP (Automatic Train Protection) unit of a certain train loses wireless communication with the trackside ATP unit After contact, the trackside ATP unit cannot know the current location of the on-board ATP unit

Embodiment 1

[0065] This embodiment provides a method for train screening, which is used to complete the screening operation as soon as possible for trains that re-report location information. The execution subject of this embodiment is a train screening device, and the train screening device can be integrated into the ATP system. More specifically, the ATP system is divided into an on-board ATP unit and a trackside ATP unit, and the train screening device can be integrated into the trackside ATP unit.

[0066] like figure 1 As shown, it is a schematic flowchart of the method for train screening according to this embodiment. Methods for this train screening include:

[0067] Step 101: Determine each first target section that a first target train may be in after the position loss occurs, and the first target section is one of the physical sections.

[0068] There are many specific ways of how to determine each first target segment, which can be performed in any manner in the prior art, o...

Embodiment 2

[0083] This embodiment further describes the train screening method of the first embodiment. This embodiment mainly provides specific examples of how to add tag information to each first target section.

[0084] Taking the first target train as an example, adding the marking information of the target train to the first target section includes:

[0085] According to the situation that the first target section is occupied by a third target train and the idle length, determine whether the first target train can enter or leave the train from a target side, the target side being the first side of the first target section and one of the second sides, the first side being opposite the second side;

[0086] If the determination result is yes, the first target section is added with marker information corresponding to the target side, and the marker information is the identifier of the first target train.

[0087] For a first target segment, it has two sides, a first side and a second...

Embodiment 3

[0104] This embodiment specifically illustrates the method for train screening in the above embodiment.

[0105] In this embodiment, a first target train and a second target train have lost positions, and the third target train and the fourth target train are trains that can always report their positions normally. The identifier of the first target train is id1, the identifier of the second target train is id2, the identifier of the third target train is id3, and the identifier of the fourth target train is id4. Each train should report its current position periodically, eg to the trackside ATP system. In this embodiment, if a physical section may be occupied by a train whose position has been lost, the identification of the train is attached to the physical section as mark information.

[0106] like image 3 As shown, the first target train 301 is traveling along the D1 side, the third target train 303 is the train behind the first target train 301, the fourth target train ...

Abstract

The invention provides a train screening method and device.The method comprises the steps that a train track where a train is located comprises at least two physical sections which are sequentially connected end to end, axle counters are arranged at the two ends of each physical section, and the method comprises the steps that first target sections where a first target train possibly exists after position loss occurs are determined, the first target section is one of the physical sections; if a current position which is reported again after the position of a first target train is lost is obtained, obtaining each piece of mark information of a first target section corresponding to the current position; judging whether information indicating that the first target section is possibly occupied by a second target train exists in each piece of mark information or not, wherein the second target train is another train of which the position is lost; and if the judgment result is no, determining that the train screening is successful. According to the invention, train screening can be completed rapidly and accurately.

Description

technical field [0001] The invention relates to the technical field of rail transportation, in particular to a method and device for screening trains. Background technique [0002] In rail transit technology, in order to ensure the safety of trains, it is usually necessary to screen the trains after the train positioning is completed, that is, to screen the hidden vehicles in front and rear of the train, such as faulty vehicles and non-reporting vehicles. [0003] There are many situations in which trains need to be screened. For example, when the on-board ATP (Automatic Train Protection) unit of a train loses wireless communication with the trackside ATP unit, the trackside ATP unit cannot know the current location of the on-board ATP unit. . Due to the loss of communication, the current vehicle is in the degraded mode. After the on-board ATP unit and the trackside ATP unit are re-established, the train screening needs to be completed. After the train was screened success...
