Technical Field

The present invention relates to the field of rail transit technologies, and in particular, to a method and an apparatus for displaying train route information, an electronic device, and a storage medium.

Background

In order to facilitate the dispatcher to analyze and adjust the driving operation in time, an Automatic Train Supervision (ATS) system needs to display the movement authorization and the Train position of the Train in real time. The movement authorization means that the maximum distance allowed by a certain train to move in a real-time running state can be displayed as the distance between the train head and a movement authorization point on a track. The train position refers to a specific position of the train on the track, and the distance between the front end and the rear end of the train can be displayed on the track. The movement authorization has obvious similarity with the display of the train position, and can be abstracted into the display between two end points on the track.

Currently, existing ATS systems generally rely on code implementation for displaying between two endpoints on a track. Such a display mode is generally rough, a situation that the movement authorization of one train conflicts with the train position of another train easily occurs, and when the display accuracy of the movement authorization or the train position needs to be changed, the code needs to be changed, so that the operation is very troublesome.

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.

The movement authorization has obvious similarity with the display of the train position, and can be abstracted into the display between two end points on the track. Currently, existing ATS systems generally rely on code implementation for displaying between two endpoints on a track. This display mode lacks interface configurability, and when the display accuracy of the movement authorization or train position needs to be changed, the operation is very troublesome because the code needs to be changed.

The configuration is used as an interface building mode, the interface can be configured in a configuration mode, and the method has the advantages of easiness in learning and use, universality, continuity, expandability and the like. In contrast, the embodiment of the invention provides a method for displaying train route information by adopting a configuration mode. Fig. 1 is a schematic flow diagram of a method for displaying train route information, the method being implemented by an ATS system, as shown in fig. 1, the method including:

step 110, constructing configuration parameters of the train to be displayed based on the relevant state information of the train to be displayed; the relevant state information comprises the path information of the train to be displayed, and the path information is movement authorization or the position of the train;

step 120, shifting a corresponding linear graphic element in a pre-established configuration file based on the shift parameter included by the configuration parameter, and displaying the shifted linear graphic element;

the offset parameter is used for indicating positions of two endpoints of the path information on corresponding track primitives in the configuration file, the track primitives and the straight line primitives are correspondingly arranged, and the straight line primitives represent the path information on the corresponding track primitives.

Here, the train to be displayed is a train that needs to display the route information on the ATS system, and the related status information, that is, the status information related to the train operation to be displayed, may include the route information of the train to be displayed, and may also include other status information, such as a track status, and the like. The route information of the train to be displayed refers to information related to the train running route and having an end point characteristic, and may be, for example, a movement authorization of the train or a train position of the train.

It should be noted that the train position herein refers to the precise position of the train on the track, and the train position can be displayed as the distance between the front end and the rear end of the train on the track. The track primitive may be a switch primitive established for a switch, or may be a turnout-free track primitive established for a common track, which is not specifically limited in this embodiment of the present invention.

Specifically, in order to implement real-time display of path information on a track by using a configuration mode, in the embodiment of the present invention, a track primitive is constructed in advance by using a configuration tool to represent track information, then a corresponding straight line primitive is added on the basis of the track primitive, the path information on the corresponding track primitive is represented by using the straight line primitive, information such as a state and a display rule of each primitive is configured in advance, a configuration file is constructed by using the method, and on the basis, an ATS system can start an actual display process of train path information:

firstly, loading a pre-constructed configuration file, and constructing configuration parameters of a train to be displayed according to related state information of the train to be displayed, wherein the configuration parameters comprise offset parameters for indicating the positions of two endpoints of path information on corresponding track primitives; then, according to the offset parameter, the linear graphics primitives needing to be offset are searched in the configuration file, then the two end points of the linear graphics primitives are accurately offset, and the offset linear graphics primitives are displayed, so that the accurate display of the specific position of the path information is realized, and the problem that the path information of two trains is easy to conflict due to rough display is avoided.

For example, one end point of the indicated path information in the offset parameter is located at a position close to an end point a on a certain non-branching track primitive (two ends are represented by A, B, respectively), the other end point is located at a position close to an end point B on the track primitive, and the distances from the two end points to the end points a and B are both 1/3 of AB-segment distances, so that only one straight line primitive to be offset at this time, that is, a straight line primitive drawn by using A, B as an end point, may offset both end points of the straight line primitive towards the middle direction by 1/3 of the AB-segment distance, and finally, the offset straight line primitive may be obtained and displayed, so as to facilitate the user to view the position where the path information of the train is to be displayed.

According to the method provided by the embodiment of the invention, the display between two end points on the track is realized by pre-constructing the track pixel and the linear pixel in the configuration file and adopting the configuration mode, so that the display can be configured, when the display needs to be modified, the configuration file only needs to be modified by a configuration tool, the convenience and the rapidness are realized, and the linear pixel used for representing the path information is accurately offset by the offset parameter based on the configuration parameter, so that the movement authorization and the train position of the train can be accurately displayed.

Based on any one of the embodiments, the track primitives are turnout primitives or turnout-free track primitives;

if the track primitive is a turnout primitive, the track primitive corresponds to three straight line primitives, namely a straight line primitive before turnout, a positioning straight line primitive and a reverse straight line primitive;

and if the track primitive is a turnout-free track primitive, the track primitive only corresponds to one straight line primitive.

Specifically, considering that the track primitive may be a switch primitive or a turnout-free track primitive, when the existing ATS system displays two end points on a track, if an end point of the path information falls on the switch, the specific position of the end point on the switch is not finely distinguished, but the whole switch is fully paved. The mode is particularly rough to display at the turnout, which can cause that in the limit operation state, if one train is in front of the turnout, the subsequent train sets the movement authorization terminal to the position of the current turnout, and the movement authorization of one train is overlapped with the train position of another train.

Aiming at the problem, the embodiment of the invention provides a method for accurately displaying the position of train path information on a turnout, namely, according to the turnout position, three conditions of front turnout, positioning and reverse positioning exist in advance, three corresponding straight line primitives are constructed for each turnout primitive in a configuration file, namely, the straight line primitive before the turnout, the positioning straight line primitive and the reverse positioning straight line primitive are respectively constructed, on the basis, if the position of any end point of the path information indicated in an offset parameter on the turnout primitive is front turnout, positioning or reverse positioning, the corresponding straight line primitive before the turnout, the positioning straight line primitive or the reverse positioning straight line primitive can be offset, and therefore, the accurate display of the position of the path information on the turnout is realized.

In addition, if the track primitive is a turnout-free track primitive, only a corresponding straight line primitive needs to be constructed for the turnout-free track primitive in the configuration file, that is, the straight line primitive drawn by taking two endpoints of the turnout-free track primitive as endpoints, and at this time, if any one endpoint of the path information in the offset parameter indicates the position of the turnout-free track primitive, the straight line primitive can be directly offset.

Based on any of the above embodiments, the relevant state information further includes the running direction of the train to be displayed;

if any end point of the path information is on the turnout primitive, the related state information also comprises the turnout direction of the turnout primitive;

the offset parameter is determined based on the positions of the two end points of the path information, and the direction of travel or the direction of travel and the direction of the switch.

Specifically, considering that the switch primitives have different switch directions, if any one of the two end points of the path information exists on the switch primitive, the related state information of the train to be displayed may further include the switch direction of the switch primitive where the end point is located, and on this basis, the offset parameter in the configuration parameter may be determined according to the positions of the two end points of the path information included in the related state information, the running direction of the train to be displayed, and the switch direction of the switch primitive, so as to offset the straight line primitive subsequently based on the offset parameter.

In addition, if the two endpoints of the path information are both on the turnout-free track primitive, only the offset parameter in the configuration parameters needs to be determined according to the positions of the two endpoints of the path information included in the relevant state information and the running direction of the train to be displayed.

Based on any of the above embodiments, step 120 further includes:

and if any end point of the path information is on the turnout primitive, hiding a straight line primitive irrelevant to the position of the end point in the three straight line primitives based on the display parameters included by the configuration parameters.

Specifically, considering that one turnout primitive corresponds to three straight line primitives, path information of one train only occupies two straight line primitives at most. In order to make the display of the path information clearer and avoid the occupation of other trains so as to generate train conflict, after determining that any end point of the path information exists on the turnout primitive, according to the display parameters included by the configuration parameters, the embodiment of the invention firstly hides the straight line primitive irrelevant to the position of the end point in the three straight line primitives corresponding to the turnout primitive, and then according to the offset parameters included by the configuration parameters, offsets the remaining straight line primitives in the three straight line primitives, namely the straight line primitive where the end point is located.

For example, if one end point of the path information of the train to be displayed is located before the turnout of the turnout primitive, and the other end point is located at the position of the turnout primitive, the reverse straight line primitive corresponding to the turnout primitive can be hidden according to the display parameters, then the positioning straight line primitive corresponding to the turnout primitive and the straight line primitive before the turnout are shifted according to the shift parameters, and finally the two shifted straight line primitives can form the straight line primitive for displaying the complete path information.

Based on any embodiment, the relevant state information is sent to the ATS system by the train-mounted system of the train to be displayed.

Specifically, in consideration of the fact that the existing ATS system needs to acquire data from the ground system and the vehicle-mounted system respectively when displaying between two end points on a track, fig. 2 is a data flow diagram of a display method of train path information provided in the prior art, and as shown in fig. 2, movement authorization and track states (such as switch location and inversion) are acquired from the ground system, and train positions are acquired from the vehicle-mounted system.

To solve the problem, in the embodiment of the present invention, a data flow structure is changed, information that needs to be obtained originally through the ground is completely transferred to a vehicle-mounted system, fig. 3 is a data flow diagram of the display method of train path information provided by the present invention, as shown in fig. 3, an ATS system only needs to obtain relevant state information from the vehicle-mounted system of a train to be displayed, where the relevant state information may include movement authorization, a train position, and a track state related to the movement authorization and the train position, etc. of the train to be displayed, and on this basis, the train path information may be displayed, so that the display method can meet the requirement of a "train-vehicle communication" architecture by adjusting a data obtaining flow.

Based on any of the above embodiments, the configuration file is created based on the following steps:

constructing a track primitive and a corresponding straight line primitive;

and configuring the style, the state matching rule and the layout of each graphic element, and storing all configured contents into a configuration file.

Specifically, in order to implement real-time display of path information on a track by using a configuration mode, an embodiment of the present invention obtains a configuration file by configuration of a configuration tool in advance, fig. 4 is a flow diagram of a configuration file establishing method provided by the present invention, and as shown in fig. 4, a track primitive is established to represent track information, and a corresponding straight line primitive is added on the basis of the track primitive; then configuring the style, state matching rule and layout of each graphic primitive; and finally, storing all the configured contents into a configuration file to obtain a complete configuration file for displaying subsequent train path information.

Here, the state matching rule is a corresponding matching rule set according to the state of the primitive, and may include, for example, a color display rule, a hiding and shifting rule of a straight line primitive, and the like, which is not specifically limited in this embodiment of the present invention.

Based on any of the above embodiments, since the end a and the end B are defined in the drawing parameters, after the layout of each primitive is configured and the layout diagram is obtained, the end a and the end B of each primitive can be defined in the layout diagram. Fig. 5 is an exemplary diagram of a layout diagram provided by the present invention, and as shown in fig. 5, the layout of the a terminal and the B terminal in the layout diagram is as follows:

1. for the graphics primitive without turnout tracks, the left end is an A end, and the right end is a B end;

2. for the turnout primitive, the front turnout part, the positioning turnout part and the reverse turnout part all take the end close to the turnout core as the end A and the end far away from the turnout core as the end B.

Then, the ID (Identity document) of each primitive may be set in units of primitives, and the ID configuration mode may be arbitrarily set according to the user requirement, which is not specifically limited in the embodiment of the present invention. For example, the ID of the straight line primitive corresponding to the turnout-free TRACK primitive may be defined as ID _ TRACK, and ID _ TRACK is set to 2; the IDs of the three linear primitives corresponding to the SWITCH primitive are respectively, before-SWITCH linear primitive ID _ SWITCH _ FRONT ═ 4, positioning linear primitive ID _ SWITCH _ NORMAL ═ 5, and inversion linear primitive ID _ SWITCH _ REVERSE ═ 6. If the front of the train falls at a position where the 1-TRACK primitive is at distance A endpoint 1/3, it is necessary that the straight line primitive with ID _ TRACK corresponding to that TRACK primitive be shifted 1/3 toward the middle at the A endpoint.

Based on any of the above embodiments, fig. 6 is a second schematic flow chart of the method for displaying train path information according to the present invention, as shown in fig. 6, after a configuration file is pre-established, the ATS system may start a display program of train path information, load the configuration file through the configuration file loading library and store the configuration file in a memory, a background module of the system constructs a configuration parameter of a train to be displayed according to related state information of the train to be displayed, which is acquired in real time, and sends the configuration parameter to a foreground interface, the foreground interface finds a corresponding primitive according to the configuration parameter received in real time and a pre-configured state matching rule, and displays a corresponding state, thereby finally realizing display of train path information. In addition, when the display state is abnormal, the configuration parameters are obtained again.

Here, the configuration parameters may be generated according to the position distribution of the two end points of the path information, and the running direction of the train and the switch direction of the switch related to the path information. As shown in fig. 5, the direction of the arrow in the figure is the running direction of the train, and is defined as descending from left to right and ascending from right to left. The direction of the turnout is the direction from the back of the turnout (positioning or reverse) to the front of the turnout, as shown in fig. 5, the direction of 1-turnout is an upward direction, the direction of 2-turnout is an upward direction, the direction of 3-turnout is a downward direction, and the direction of 4-turnout is a downward direction.

The configuration parameter construction table can be pre-established according to all the conditions of the position distribution of the two end points of the path information, and on the basis, after the two specific positions of the path information of the train to be displayed are determined, the configuration parameter of the train to be displayed can be directly constructed by searching the configuration parameter construction table.

The configuration parameter construction table may include the following:

1. the starting end (i.e. the starting end in the train running direction) and the terminal end (i.e. the terminal end in the train running direction) of the path information are on the same track primitive:

a. the starting end and the rear end are both in front of the turnout element: for example, before the 1-switch primitive in fig. 5 is switched, the positioning straight line primitive and the inverted straight line primitive of the 1-switch primitive need to be hidden, the offset ratio of the a end of the straight line primitive before the switch is the starting end offset ratio, and the offset ratio of the B end is the 1-terminal end offset ratio (the starting end offset ratio and the terminal end offset ratio are both calculated relative to the a end point);

the moving direction is upward, the switch direction is downward, for example, before the switch of the 3-switch primitive in fig. 5, the positioning straight line primitive and the inverted straight line primitive of the 3-switch primitive need to be hidden, the offset ratio of the end a of the straight line primitive before the switch is the terminal offset ratio, and the offset ratio of the end B is the starting offset ratio;

the moving direction is downward, the switch direction is upward, for example, before the switch of the 2-switch primitive in fig. 5, the positioning straight line primitive and the inverted straight line primitive of the 2-switch primitive need to be hidden, the offset ratio of the end a of the straight line primitive before the switch is the terminal offset ratio, and the offset ratio of the end B is the starting offset ratio;

for example, before the 4-switch primitive in fig. 5 is switched, the positioning straight line primitive and the inverted straight line primitive of the 4-switch primitive need to be hidden, the offset ratio of the end a of the straight line primitive before the switch is the starting offset ratio, and the offset ratio of the end B of the straight line primitive before the switch is the terminal offset ratio of 1.

b. The starting end and the rear end are positioned or reversed on the turnout primitive, similar to the situation of a, and similar reasoning can be carried out.

c. The starting end and the rear end are positioned at different positions (positions) of the turnout primitive, and the turnout state is positioned at the moment: for example, the start end is positioned in the 1-switch primitive in fig. 5, and the end is before the switch, the reverse straight line primitive of the 1-switch primitive needs to be hidden, the offset ratio of the end a of the straight line primitive before the switch is 0, the offset ratio of the end B of the straight line primitive before the switch is 1-end offset ratio, the offset ratio of the end a of the positioning straight line primitive is 0, and the offset ratio of the end B of the positioning straight line primitive is 1-start end offset ratio;

the moving direction is upward, the switch direction is downward, for example, the start end is before the switch of the 3-switch primitive in fig. 5, and the end is positioned, then the reverse straight line primitive of the 3-switch primitive needs to be hidden, the a-end offset ratio of the straight line primitive before the switch is 0, the B-end offset ratio is 1-start-end offset ratio, the a-end offset ratio of the positioning straight line primitive is 0, and the B-end offset ratio is 1-end offset ratio;

the moving direction is downward, and the switch direction is upward, for example, the start end is before the switch of the 2-switch primitive in fig. 5, and the end is positioned, then the reverse straight line primitive of the 2-switch primitive needs to be hidden, the a-end offset ratio of the straight line primitive before the switch is 0, the B-end offset ratio is 1-start-end offset ratio, the a-end offset ratio of the positioning straight line primitive is 0, and the B-end offset ratio is 1-end offset ratio;

for example, the start end is positioned in the 4-switch primitive in fig. 5, and the end is before the switch, the reverse straight line primitive of the 4-switch primitive needs to be hidden, the a-end offset ratio of the straight line primitive before the switch is 0, the B-end offset ratio of the straight line primitive before the switch is 1-end offset ratio, the a-end offset ratio of the positioning straight line primitive is 0, and the B-end offset ratio of the positioning straight line primitive is 1-start end offset ratio.

d. The starting end and the rear end are at different positions (reverse positions) of the turnout primitive, the turnout state is reverse position at the moment, and similar reasoning can be carried out as the situation of c.

e. The starting end and the rear end are on the turnout-free track primitive: the running direction is an upward direction, for example, in the 1-track primitive or the 3-track primitive in fig. 5, the a-end offset ratio of the straight line primitive corresponding to the 1-track primitive or the 3-track primitive is equal to the terminal offset ratio, and the B-end offset ratio is equal to the 1-start offset ratio;

for example, in the 2-track primitive or the 4-track primitive in fig. 5, the a-end offset ratio of the linear primitive corresponding to the 2-track primitive or the 4-track primitive is equal to the start-end offset ratio, and the B-end offset ratio is equal to the 1-end offset ratio.

2. The starting end and the terminal end of the path information are in different track primitives:
