Problems solved by technology

[0005] In the process of using the above general train tracking method, since it takes a certain amount of time to judge the fault of the ATP system, it will cause the train tracking to stop during the switching process of the tracking mode
In addition, when a train communication failure occurs, or a non-communication vehicle enters the monitoring range, the above-mentioned tracking scheme cannot track the train in time.

Embodiment 1

[0032] The applicant of this case found that the current two train tracking modes of moving block and fixed block work independently, that is, when the ATS system is working, only one of the tracking modes is used. When there is an abnormality (such as train communication failure, non-communication vehicles entering the monitoring range, etc.), the train tracking cannot be carried out continuously. Therefore, the applicant of this case proposes a mixed-running train tracking method for the first time, that is, the two modes of general train tracking (moving block and fixed block tracking mode) are simultaneously applied to the ATS system. In this way, the ATS receives ATP data (data collected in the existing mobile block tracking mode) and CI data (data sampled in the existing fixed block tracking mode) in real time, and whichever data is received first will be used for train tracking. . It can be seen from this that this solution combines the advantages of the two existing t...

Embodiment 2

[0042] This embodiment provides an automatic train monitoring system, which at least includes a collection unit and a processing unit.

[0043] Among them, the acquisition unit receives the data sent by ATP and CI in real time;

[0044] The processing unit, whenever the receiving unit receives data, performs train tracking and step calculation according to the currently received data.

[0045] In some other solutions, on the basis of the above system, an electronic map unit is added, and the unit designs a directed electronic map in advance according to the topological structure of the train running line. In this way, when the processing unit receives the data, it searches the traveling path of the train from the directional electronic map, and performs step-by-step calculation according to the search result and the currently received data, so as to realize the train tracking. Specifically, for the process of designing the directional electronic map for the electronic map uni...

Abstract

The invention relates to an automatic train supervision system and a train tracking method and belongs to an automatic train supervision technique. The train tracking method disclosed by the invention comprises the following steps: receiving data sent from an automatic train protector (ATP) and an interlock system by an automatic train supervision (ATS) system in real time, and performing stepping calculation according to the received data when the data is received each time, thereby realizing train tracking. By adopting the technical scheme of the invention, the train can be continuously tracked during a switching process in a tracking mode and under the conditions of a train communication fault and a non-communication train driving into a monitored scope.

Description

technical field [0001] The invention belongs to the train automatic monitoring technology, and particularly relates to an automatic train monitoring system and a train tracking method. Background technique [0002] Train tracking is an important part of the automatic train control system (ATC, Automatic Train Control). , it can be said that the strategy and algorithm of train tracking directly affect the quality of automatic train supervision (ATS) system. Currently, train tracking is based on continuous equipment status information collected from interlocking systems to determine train position and train movement. Among them, the process of the train running from one position to the adjacent position is called stepping, and the process of train tracking is the process of calculating the train stepping. [0003] Usually when the mobile blocking equipment is normal, the train tracking adopts the mobile blocking tracking mode, and the ATS continuously receives the train stat...
