Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Fig. 1 is a schematic flow chart of a method for turning back a train according to the present invention. As shown in fig. 1, a method for turning back a train according to an embodiment of the present invention includes: and step 101, acquiring information of a return section occupied by the target train.

It can be understood that the urban rail transit signal system is generally composed of an Automatic Train Control (ATC), and the ATC includes three subsystems: an Automatic Train monitoring system (ATS), an Automatic Train Protection system (ATP), and an Automatic Train Operation system (ATO).

The three subsystems form a closed-loop system through an information exchange network, realize the combination of ground control and on-board control and the combination of local control and central control, and form an automatic train control system which is based on safety equipment and integrates the functions of train command, operation adjustment, train driving automation and the like.

The ATO system is used for adjusting the speed of the train by controlling the traction and the braking of the train, so that the train can run more stably, the arrival and the stop can be more accurate, and the switching between the head and the tail of the train can be completed more quickly to shorten the time required by turning back.

The ATP system is used to secure a safe separation distance between two trains by displaying a signal to a driver to prevent a collision (rear-end collision, head-on collision, or side collision).

The ATS system is used for keeping the balanced distance of all on-line trains by controlling the stop time of each train at a station and the running speed of each train in an interval, and avoiding congestion or large neutral gear among the trains.

The main body of the execution of the train folding back method is a train folding back system, and the target of the execution of the folding back method is a train provided with the train folding back system. The train can be a rail vehicle such as a subway, a train or a light rail, and the type of the train is not particularly limited in the embodiment of the invention.

Preferably, the target train is a subway train formed by connecting a plurality of cars together, wherein the train consist refers to the composition and the composition of the train, namely, the train types are combined in a preset number according to a corresponding arrangement mode.

The target train is classified into a large-consist train and a small-consist train according to the number of the vehicles in the train consist corresponding to the target train.

Preferably, the large consist train is an eight car consist and the small consist train is a four car consist.

The turning-back section is a section which is provided at a terminal station or an intermediate station at both ends of a line and is specially used for changing the running direction of a train to enable the turning-back train to run.

Specifically, the retracing system of the train acquires a retracing section of the pressure occupied when the target train stops, and acquires information of the retracing section from the ATC system.

The embodiment of the present invention does not specifically limit the content and storage manner of the information in the foldback section.

Preferably, the information of each turnaround section at least includes a turnaround section ID to know the turnaround section occupied by the train. And storing the data in a database in the ATS system in a table form, wherein the horizontal row of the table can be the ID of the foldback section, and the vertical column can be the related information field of the foldback section and the corresponding content thereof.

And 102, under the condition that the number of the turning sections occupied by the target train is not less than 2 and the information of the turning sections occupied by the target train contains the target attribute information, taking the combination of the turning sections occupied by the target train as a turning area, and controlling the target train to turn according to the turning area.

The target attribute information is used for representing the turn-back section as a candidate section of the turn-back area of the target train.

It should be noted that, in principle, each of the turnaround sections can be used as a turnaround area for a small consist. The target attribute information belongs to one kind of information of the foldback section. The information of each of the turnaround sections includes target attribute information indicating that the turnaround section can be used as a part of a turnaround area of the large train set for turnaround of the large train set.

Specifically, after the return system of the train acquires information of all return sections occupied by the target train, judging the occupied pressure condition of the target train from two aspects of the number of the occupied pressure return sections and the information content based on the acquired information, combining all the return sections occupied by the target train to obtain the return area of the target train under the condition that the acquired information of all the return sections of the occupied pressure condition meets the occupied pressure condition that the number of the return sections is not less than 2 and the information of all the return sections of the occupied pressure condition contains attribute information for representing that the return sections can be used as a part of the return area of the large marshalling train, and receiving a control instruction from an ATC system to enable the target train to return in the obtained return area.

The number of the pressure-occupied return sections is judged, the number of the pressure-occupied return sections is obtained according to the information of all the pressure-occupied return sections, and the pressure-occupied return sections are compared with a preset threshold value to obtain a comparison result. Wherein, the comparison result is divided into two types, one is qualified in comparison, and the other is unqualified in comparison.

And if the comparison is qualified, the number of the turning sections occupied by the target train is not less than 2, which indicates that the turning area of the target train needs to be formed by combining at least two turning sections.

And if the comparison is unqualified, the number of the turning sections occupied by the target train is less than 2, the turning area of the target train is the current occupied pressing turning section, and the combination is not needed.

The method for acquiring the number of the pressure-occupied return sections in the embodiment of the present invention is not particularly limited. For example, a sensor may be provided in the retrace section, and the ATC system automatically acquires the number of sensors that generate sensing when the train stops and transmits the number of sensors to the retrace system of the train. The number of the sections can be counted by the train turning-back system according to the section ID in the obtained turning-back section information with the pressure.

And judging the information content of the secondary pressure folding section, searching according to the information of each compressed folding section and the target attribute information to obtain a query result. The query result is divided into two types, one is a successful query, and the other is a failed query.

If the query is successful, that is, the information of each occupied folded section contains the target attribute information, it indicates that all the occupied folded sections can be combined into the folded area of the target train.

And if the query fails, the information of at least one occupied turning section does not contain the target attribute information, and the result shows that all occupied turning sections cannot be combined into the turning area of the target train.

It can be understood that the storage form set for the target attribute information determines the determination manner of the information content occupying the fold-back section, and the storage form of the target attribute information and the determination method of the information content occupying the fold-back section are not particularly limited in the embodiment of the present invention.

For example, the target attribute information may be added to corresponding fields in the train turning-back section information in the form of storage of characters "Y" and "N", and when the information content of the occupied turning-back section is judged, the character content may be retrieved under the corresponding field of each of the pressed turning-back section information. The results of retrieving the character content can also be counted, if the total number of the Y is equal to the number of the pressed turning sections, the result is that the query is successful, and the results corresponding to all the other conditions are that the query is failed.

The embodiment of the invention judges the marshalling condition of the train according to the number of the retracing sections occupying the pressure of the target train based on the information of the retracing sections occupying the pressure of the target train, and connects and configures the retracing sections of the attribute information to form a large marshalling retracing area through the target attribute information after acquiring the condition that the train is a large marshalling train, thereby saving line resources or avoiding the condition of being limited by the line resources and realizing more flexible retracing of the large marshalling train.

In addition to any of the above embodiments, when the number of the turning sections occupied by the target train is not less than 2 and the information of the turning sections of each occupied pressure includes the target attribute information, a combination of the turning sections of each occupied pressure is used as a turning area, and the target train is controlled to turn back according to the turning area, the method includes:

based on the information of the turn-back sections of each pressure, the section ID corresponding to the turn-back section of each pressure is acquired.

Specifically, the train turning-back system acquires the section ID of each turned-back section under the occupied pressure from the information of the turned-back section under the occupied pressure acquired in step S101.

And when the number of the turning sections occupied by the target train is not less than 2, the information of the turning sections of each occupied pressure comprises target attribute information, and the turning sections of each occupied pressure are determined to be continuous sections based on the section ID corresponding to the turning sections of each occupied pressure, the combination of the turning sections of each occupied pressure is used as a turning area, and the target train is controlled to turn back according to the turning area.

Specifically, the turning-back system of the train judges the continuous condition of the turning-back sections occupied by the pressure according to the acquired section IDs of all the turning-back sections occupied by the target train, combines all the turning-back sections occupied by the target train to obtain a turning-back area of the target train when three conditions are met, and receives a control instruction from the ATC system, so that the target train turns back in the turning-back area.

The first condition is that the number of the turning sections meeting the pressure occupation condition is not less than 2 when the pressure occupation condition is known; the information of the turn-back sections under the second condition comprises attribute information for representing that the turn-back sections can be used as part of a turn-back area of the large-marshalling train; the third condition is that all the turn sections of the pressure are continuous.

The embodiment of the invention judges the marshalling condition of the train according to the number of the retracing sections occupying the pressure based on the information of the retracing sections occupying the pressure of the target train, and then connects and configures the retracing sections of the attribute information according to the sequence of the target attribute information to form the large marshalling retracing area after acquiring the condition that the train is a large marshalling train.

On the basis of any of the above embodiments, before acquiring information of a turnaround section occupied by a target train, the method further includes:

for each of the turnaround sections, in the case where the turnaround section is a candidate section of the target train turnaround area, target attribute information is added to information of the turnaround section.

It should be noted that the information of all the turnaround sections is stored in the database of the train turnaround system and/or the database of the ATC system, and the storage of the information of the turnaround sections is not particularly limited in the embodiment of the present invention.

Specifically, all the fold-back sections are counted, and for each fold-back section required to be a fold-back area of a large-consist train, target attribute information for characterizing the fold-back area combinable into the large-consist train is added under a corresponding field in the information of the fold-back section.

The embodiment of the invention is based on configuring the target attribute information of the turn-back sections which can be used as the turn-back areas of the turn-back of the large marshalling train, so that the small marshalling train can be normally turned back, and the turn-back sections with the attribute can be sequentially connected and configured through the attribute to form the turn-back areas of the large marshalling train.

On the basis of any of the above embodiments, after obtaining the information of the turning back section of the target train occupation pressure, the method further includes: and when the number of the turning sections occupying the pressure of the target train is less than 2, taking the turning sections occupying the pressure as turning areas, and controlling the target train to turn according to the turning areas.

Specifically, in step S102, after the turning-back system of the train acquires information of all turning-back sections of the target train occupation pressure, the number of the turning-back sections of the occupation pressure is acquired based on the acquired information of all turning-back sections of the occupation pressure, and is compared with a preset threshold value to acquire a comparison result. And if the comparison result is unqualified, namely the number of the turning sections occupying the pressure of the target train is less than 2, taking the turning section occupying the pressure of the target train at present as the turning area of the target train, and receiving a control command from the ATC system to turn the target train in the obtained turning area.

An example of an embodiment of setting a train turnaround will now be described.

For example, in principle, each small consist train can normally make a retrace pass in a retrace section, so when occupying one retrace section, the train retrace system directly receives an ATC command to make a retrace in the retrace section. Therefore, when a train stops at the turnaround block _41 and turnaround block _42, the train is a large-consist train.

As known from the train foldback system, block _41 and block _42 are each marked with target attribute information "Y," indicating that these two foldback zones can be combined into a foldback region of the train, i.e., area _ block _41+ block _42 or area _ block _42+ block _ 41. When the area of the train is a combination of block _41 and block _42, the original route of the train is folded from a small mileage to a large mileage. When the area of the retracing is a combination of block _42+ block _41, the travel route of the train is to be retraced from a big mileage to a small mileage. The retracing area formed by combining the retracing sections can be used for retracing the trains in two driving directions.

When a train stops at a retracing section block _41 and a retracing section block _42, the train retracing system learns that both block _41 and block _42 are marked with target attribute information 'Y', which indicates that the two retracing sections can be combined into a retracing section of the train, and determines that block _41 and block _42 are continuous sections through section IDs, the retracing sections are combined in a front-back sequence, which can be represented as area _41+ block _42, that is, the travel route of the train is retraced from a small mileage to a large mileage.

The method and the device for judging the train formation condition of the small-formation train can enable the small-formation train to normally turn back on the turn-back section with the current pressure on the basis of the information of the turn-back section with the pressure occupied by the target train and judge the train formation condition of the train through the number of the turn-back sections with the pressure occupied.
