Description

Technical Field

[0001] The present invention relates to the technical field of rail transit, and particularly to a method and system for generating train movement authority. Background Art

[0002] For the Communication-based Train Control (CBTC) 2.0 project, the functional tests of the Automatic Train Protection (ATP), Automatic Train Operation (ATO), and Human Machine Interaction (HMI) of trains are mostly carried out in special tests. In the special test environment, the Zone Controller (ZC), Computer Interlocking (CI), and Automatic Train Supervision (ATS) all use a communication interface platform and simulation models for simulation. The simulation models are more practical than physical objects during use and can send corresponding data to ATP, ATO, HMI, etc. according to different test scenarios. However, during the use of the simulation models, testers need to judge the correctness of the sent data. Sending incorrect data during the test will cause the connection between ATP and the simulation models to be disconnected, and the process of checking problems and resetting the data will delay part of the test time.

[0003] The traditional ZC test model used in on-vehicle special tests, which is used to simulate the real ZC to send Movement Authority (MA), requires setting the track section position, platform screen door status, running direction, emergency stop button (ESB) status, switch status, on-rail personnel operation protection switch (SPKS), speed limit, and protection section, etc. on the ZC test model interface. During the process of setting the movement authority, if there is one error, it will cause the train ATP to lose positioning and degrade.

Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art without creative efforts based on the embodiments in the present invention belong to the scope of protection of the present invention.

[0031] The train movement authorization generation method provided by the present invention can be applied to the on-vehicle special test of the CBTC2.0 project. Its purpose is to provide a test method for automatically generating train movement authorization, so that during the test process, the ZC simulation model can automatically generate selectable movement authorizations for testers according to the area where the train ATP is set. The specific implementation is as follows:

[0032] Figure 1 is a schematic flowchart of the train movement authorization generation method provided by the present invention. As Figure 1 shown, the method includes:

[0033] Step 110, when the positioning information of the train is included in the simulation operation diagram, obtain the train running direction and the train envelope information;

[0034] Step 120: Generate the target moving authority of the train based on the position of the train on the simulation operation diagram and the moving authority of the target route in the same direction as the train operation direction. The position is obtained according to the positioning information of the train on the simulation operation diagram when the ZC simulation model is connected to the simulation operation diagram, and the moving authority is generated based on the train operation direction, the train envelope information, and the data in the preset database.

[0035] It should be noted that the execution subject of the above method can be a computer device or a ZC simulation model. The following takes the ZC simulation model executing the above method to elaborate on the present invention in detail.

[0036] In an embodiment of the present invention, the simulation operation diagram can be specifically obtained by simulating a train operation diagram.

[0037] In an embodiment of the present invention, after the ZC simulation model determines that there is positioning information of the train on the simulation operation diagram, it obtains the train operation direction and the train envelope information. The ZC simulation model can specifically read the environmental test data of the simulation operation diagram through the network to determine whether the simulation operation diagram includes the positioning information of the train. The environmental test data at least includes the position information of the train.

[0038] In an embodiment of the present invention, the ZC simulation model generates the target moving authority of the train based on the position of the train on the simulation operation diagram and the moving authority of the target route in the same direction as the train operation direction. The position of the train on the simulation operation diagram can be specifically the position of the train read from the simulation operation diagram by the ZC simulation model according to the positioning information of the train on the simulation operation diagram after establishing a real-time connection with the simulation operation diagram. The moving authority of the target route can be specifically generated by the ZC simulation model based on the train operation direction, the train envelope information, and the data in the preset database. The moving authority can specifically include the moving authority of the straight route of the target route, the moving authority of the lateral route, the moving authority when the protection section is valid, and the moving authority when the protection section is invalid, etc.

[0039] In an embodiment of the present invention, the data in the preset database can be specifically the data set in the database of the ZC simulation model in advance and is consistent with the information in the train ATP electronic map. The data can specifically include the data required to generate the moving authority, such as track information, platform information, platform screen door information, turnout information, etc.

[0040] In the embodiments of the present invention, the train running direction and the train envelope information may specifically be sent by the train, or may specifically be obtained by reading the simulation operation diagram. Correspondingly, the movement authorization of the target route may specifically be obtained by the ZC simulation model based on the train running direction, the train envelope information, and the data in the preset database sent by the train, or may specifically be obtained by the ZC simulation model based on the data in the preset database and the train running direction and the train envelope information obtained by reading the simulation operation diagram.

[0041] In the embodiments of the present invention, the ZC simulation model and the simulation operation diagram use the same database data.

[0042] It should be noted that in the process of the ZC simulation model generating the movement authorization of the target route according to the train running direction, the train envelope information, and the data in the preset database, the ZC simulation model may continuously interact with the train to obtain the current train running direction and the current train envelope information, or may continuously read the simulation operation diagram to obtain the current train running direction and the current train envelope information.

[0043] The train movement authorization generation method provided by the present invention, after the train completes positioning while running on the simulation operation diagram, establishes a real-time connection relationship among the ZC simulation model, the train, and the simulation operation Figure 3 diagram. The ZC simulation model generates the target movement authorization required by the train according to the position of the train on the simulation operation diagram, which can meet different test scenarios of testers, save the time for selecting data and then generating the target movement authorization, reduce the error rate, and improve the test efficiency while doing so.

[0044] Further, in one embodiment, the generating the target movement authorization of the train according to the position of the train on the simulation operation diagram and the movement authorization of the target route having the same direction as the train running direction may specifically include:

[0045] When the position of the train on the simulation operation diagram coincides with the movement authorization end point, generate the target movement authorization according to the relationship between the movement authorization end point and the target route end point.

[0046] In the embodiments of the present invention, the ZC simulation model generating the target movement authorization of the train may specifically be that when it is determined that the position of the train on the simulation operation diagram coincides with the position where the movement authorization end point calculated by the ZC simulation model is located, the ZC simulation model calculates the target movement authorization for the train according to the relationship between the movement authorization end point and the target route end point.

[0047] In the embodiments of the present invention, the movement authorization end point may specifically be the end point of the movement authorization, and the target route end point may specifically be the end point of the route having the same direction as the train running direction.

[0048] Further, in one embodiment, when the position of the train on the simulation operation diagram coincides with the end point of the movement authorization, generating the target movement authorization according to the relationship between the end point of the movement authorization and the end point of the target route includes:

[0049] When the end point of the movement authorization coincides with the end point of the target route, taking the movement authorization as the target movement authorization;

[0050] When the end point of the movement authorization does not coincide with the end point of the target route, updating the movement authorization based on the current running direction of the train, the current envelope information of the train, and the data in the preset database to generate the target movement authorization.

[0051] In the embodiment of the present invention, the ZC generating the target movement authorization according to the relationship between the end point of the movement authorization and the end point of the target route may specifically refer to that when the ZC simulation model determines that the end point of the movement authorization and the end point of the target route are at the same position, the ZC simulation model takes the movement authorization of the target route calculated according to the running direction of the train, the train envelope information, and the data in the preset database as the target movement authorization of the train.

[0052] In the embodiment of the present invention, the ZC generating the target movement authorization according to the relationship between the end point of the movement authorization and the end point of the target route may also specifically refer to that when the ZC simulation model determines that the end point of the movement authorization and the end point of the target route are not at the same position, the ZC simulation model updates the movement authorization of the target route calculated according to the current running direction of the train, the current envelope information of the train, and the data in the preset database, and updates the target movement authorization calculated by the ZC simulation model according to the running direction of the train, the train envelope information, and the data in the preset database.

[0053] In the embodiment of the present invention, the current running direction of the train may specifically be the current running direction of the train, which may specifically be obtained by the ZC simulation model from the information sent by the train. The current envelope information of the train may specifically be the current envelope information of the train, which may specifically be obtained by the ZC simulation model from the information sent by the train.

[0054] In the embodiment of the present invention, the current running direction of the train may specifically be the current running direction of the train, which may specifically be obtained by the ZC simulation model by reading the simulation operation diagram. The current envelope information of the train may specifically be the current envelope information of the train, which may specifically be obtained by the ZC simulation model by reading the simulation operation diagram.

[0055] It should be noted that the generated target movement authorization of the present invention can be manually modified.

[0056] The train movement authorization generation method provided by the present invention enables the ZC simulation model to obtain the data of the simulation operation diagram and the data sent by the train in real time, while maintaining the communication connection between the train and the ZC simulation model. When the positioning information of the train is available on the simulation operation diagram, a connection relationship is established in real time among the train, the ZC simulation model, and the simulation operator. The ZC simulation model generates the target movement authorization required by the train according to the position of the train on the simulation operation diagram, which can meet the different test scenario requirements of testers. Figure 3 The ZC simulation model generates the target movement authorization required by the train according to the position of the train on the simulation operation diagram, which can meet the different test scenario requirements of testers.

[0057] Further, in one embodiment, when the positioning information of the train is included in the simulation operation diagram, obtaining the train running direction and the train envelope information includes:

[0058] Establishing a communication connection with the train and receiving the target information sent by the train;

[0059] Obtaining the train running direction and the train envelope information according to the target information.

[0060] In the embodiment of the present invention, when the positioning information of the train is included in the simulation operation diagram, the ZC simulation model establishes a communication connection with the train and receives the target information sent by the train. The establishment of the communication connection with the train can specifically be the establishment of a communication connection with the train ATP. The target information can specifically be sent by the train ATP.

[0061] In the embodiment of the present invention, the ZC simulation model obtains the train running direction and the train envelope information from the target information sent by the received train ATP.

[0062] The train movement authorization generation method provided by the present invention, when it is determined that the positioning information of the train is included in the simulation operation diagram, the ZC simulation model establishes a communication connection with the train and obtains the train direction information and the train envelope information sent by the train, laying a foundation for generating the movement authorization of the target route based on the train direction information, the train envelope information, and the data in the preset database, and obtaining the target movement authorization of the train according to the movement authorization.

[0063] Further, in one embodiment, the movement authorization completely covers the train safety envelope in the train envelope information.

[0064] In the embodiments of the present invention, when the movement authorization of the target route calculated by the ZC simulation model based on the train running direction, train envelope information, and data in the preset database is selected for testing, it is necessary to ensure that the train can be normally upgraded. The normal upgrade of the train can specifically mean that the movement authorization of the target route can completely cover the train safety envelope in the train envelope information. In other words, the movement authorization of the target route calculated by the ZC simulation model based on the train running direction, train envelope information (mainly using the running track where the train is located in the train envelope information), and data in the preset database needs to cover the train safety envelope.

[0065] Further, in one embodiment, the method for obtaining the train safety envelope may specifically include:

[0066] Obtain the train safety envelope according to the maximum safety front end and the minimum safety rear end of the train in the train envelope information.

[0067] In the embodiments of the present invention, the train safety envelope may specifically be the logical section between the maximum safety front end and the minimum safety rear end of the train in the train envelope information.

[0068] In the embodiments of the present invention, the ZC simulation model takes the logical section between the maximum safety front end and the minimum safety rear end of the train in the train envelope information as the train safety envelope.

[0069] For example, the test process of the ZC simulation model generating the train movement authorization may specifically be:

[0070] 1. Establish a connection state between the simulation operation diagram and the ZC simulation model, and the train ATP starts normally;

[0071] 2. After including the positioning information of the train in the simulation operation diagram, the ZC simulation model establishes a communication connection with the train ATP;

[0072] 3. The ZC simulation model receives the train envelope information (including the running track where the train is located) and the train running direction information;

[0073] 4. The ZC simulation model automatically generates the movement authorization of the target route in the same direction as the train running direction according to the train running direction, train envelope information, and data in the preset database. The types of this movement authorization include the movement authorization of the straight route of the target route, the movement authorization of the lateral route, the movement authorization when the protection section is valid, and the movement authorization when the protection section is invalid, etc.;

[0074] 5. Select the movement authorization required for testing from the ZC simulation model interface, and the train can be normally upgraded;

[0075] 6. When the train runs to the selected movement authorization end point (that is, the train position coincides with the movement authorization end point), if the movement authorization end point is the target route end point, the ZC simulation model uses the movement authorization as the target movement authorization; if the movement authorization end point is not the target route end point, the ZC simulation model calculates a new movement authorization as the target movement authorization based on the current running direction of the train, the current envelope information of the train, and the preset database data.

[0076] 7. The generated target mobile authorization can still be modified manually.

[0077] The train movement authorization generation method provided by the present invention establishes a ZC simulation model, a train and a simulation operation diagram after the train positioning information is included on the simulation operation diagram. Figure 3 The ZC simulation model calculates the target route movement authorization for the train, so that when the tester selects it, it can ensure that the train can be upgraded normally, and generates the target movement authorization required by the train according to the position of the train on the simulation operation diagram to meet the different test scenario requirements of the tester.

[0081] The data acquisition module 210 is used to acquire the train running direction and train envelope information when the simulation running diagram includes the train positioning information;

[0082] The data generation module 211 is used to generate a target movement authorization for the train based on the position of the train on the simulation operation diagram and the movement authorization of the target route with the same running direction as the train.
