Problems solved by technology

However, in some cases, a train may lose communication with the ATP system, and it cannot report its position to the ATP system, so that the train becomes a non-reporting train
If the non-reporting train is followed by a reporting train that can report its position normally, a safety accident may occur because the ATP system cannot know the position of the non-reporting train

Embodiment 1

[0046] This embodiment provides a method for determining the authorized distance of train movement. The execution subject of the method is a device for determining the authorized distance of train movement, and the device can be integrated in the ATP system. More specifically, the ATP system is divided into an on-board ATP unit and a wayside ATP unit, and the device can be integrated in the wayside ATP unit. "Front" and "rear" in this embodiment all refer to the normal running direction of the first target train, and the normal running direction of the first target train is "front".

[0047] like figure 1 As shown, it is a schematic flow chart of the method for determining the authorized train movement distance according to this embodiment. The method includes:

[0048]Step 101, determine a first target section where the first target train is located after the position loss occurs, wherein the train track where the first target train is located includes at least two physical...

Embodiment 2

[0072] This embodiment uses specific examples to further illustrate the method for determining the authorized distance for train movement in the foregoing embodiments. In this embodiment, the first target train is a non-reporting train whose location is lost, and the second target train is a reporting train that can normally report its location.

[0073] For the case where the first target train and the second target train are located in adjacent physical sections:

[0074] like Figure 2A to Figure 2C Shown is a schematic diagram of a train running on a train track. The first target train 201 travels along the first direction D1, and the second target train 202 follows the first target train 201 and also travels along the first direction D1. Wherein, the first target train 201 is located in the first target section TVS1, and the second target train 202 is located in the second target section TVS2. The first target segment TVS1 and the second target segment TVS2 are adjacen...

Embodiment 3

[0086] This embodiment provides a device for determining the authorized distance of train movement, which is used to implement the method for determining the authorized distance of train movement in the first embodiment. The device can be installed separately, or integrated in the ATP system, such as a trackside ATP unit, which can be determined according to actual needs, and will not be repeated here.

[0087] like Figure 3A Shown is a schematic structural diagram of the device for determining the authorized train movement distance according to this embodiment. The device 30 for determining the authorized train movement distance includes a determining unit 301 , a first judging unit 302 and a first processing unit 303 . Wherein, the determining unit 301 is used to determine a first target section where a first target train is located after its position is lost, wherein the train track where the first target train is located includes at least two physical sections connected ...

Abstract

The invention provides a method and device for determining a train movement authorized distance, and the method comprises the steps: determining a first target section where a first target train is located after the position of the first target train is lost, and enabling a train track where the first target train is located to comprise 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 first target section is one of the physical sections; an adjacent second target train is arranged behind the first target train, the second target train can report the position, and after the position of the first target train is lost, whether a train passes through a first axle counter or not and whether the running direction of the train is opposite to that of the first target train or not are judged, the first axle counter is located in the first target section and close to the second target section; and if the judgment result is yes, shortening the movement authorization distance of the second target train.

Description

technical field [0001] The invention relates to the technical field of railway transportation, in particular to a method and a device for determining the authorized distance of train movement. Background technique [0002] ATP (Automatic Train Protection, automatic train protection) system is the key equipment to ensure the safe operation of trains. It continuously transmits the movement authorization to the train through the ATP ground equipment installed on the trackside to ensure the safe distance between the subsequent train and the preceding train. The safe separation distance can ensure the safety between the preceding train and the adjacent following train. Each train periodically reports its position to the ATP system, so that the ATP system can accurately know the real-time position of each train, and transmit movement authorization for each train. [0003] Because there is a safe distance between the trains, even if a certain train retreats due to an unexpected s...
