Description

Technical Field

[0001] This application relates to the field of train simulation technology, and in particular to a method, device, equipment and medium for verifying train control functions. Background Technology

[0002] With the rapid development of rail transit equipment systems, higher demands have been placed on the research and testing efficiency of vehicle control systems. Currently, testing of vehicle control functions typically involves testing each subsystem / component individually, while testing of the entire vehicle mainly focuses on the interface between the subsystem / component and the vehicle control circuit.

[0003] However, due to the sheer number and variety of subsystems and components involved in a vehicle, building a vehicle-level integrated control function test system using hardware-in-the-loop simulation is virtually impractical. The design and verification of subsystem / component control functions are typically handled independently by the subsystem supplier, who builds the simulation platform. Subsystem simulation platforms often employ hardware-in-the-loop simulation, which cannot realistically and completely simulate the operation of the actual vehicle during testing. This results in low testing efficiency and limited operational coverage. Furthermore, because subsystems are tested in isolation, it's impossible to verify their interface functions with the vehicle's control circuits and control systems in advance, making it impossible to avoid modifications needed during actual vehicle debugging and verification if such issues arise.

[0004] In view of the above problems, how to enable the train subsystems to participate fully in the whole train test in order to improve the test coverage and better realize the verification of the whole train control function is an urgent problem to be solved by the technical personnel in this field.

This improves the efficiency of integrated testing and verification of the overall vehicle control function, and enhances the completeness and effectiveness of the test, while also saving costs compared to traditional semi-physical testing.

[0053] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this application.

[0054] The core of this application is to provide a method, apparatus, equipment, and medium for verifying train control functions, so that the train subsystem can fully participate in the whole train test, improve the test coverage, and better realize the verification of the whole train control functions.

[0055] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0056] With the rapid development of rail transit equipment systems, higher demands are being placed on the efficiency of R&D and testing of vehicle control systems. In traditional hardware-in-the-loop (HIL) simulation testing of subsystems / components, the integration and debugging of subsystems / components from different manufacturers requires significant manpower and resources for equipment transportation, test site setup, and wiring preparation. This is especially true when the subsystem / component to be tested is large, making it difficult to organize and provide suitable testing conditions. Therefore, for testing the overall vehicle control functions, each subsystem / component is typically tested individually, while the overall vehicle testing primarily focuses on the interface testing between the subsystem / component and the vehicle control circuit.

[0057] However, existing vehicle-level hardware-in-the-loop (HIL) simulation testing platforms are impractical due to the sheer number and variety of subsystems and components involved in a complete vehicle. The simulation models or physical prototypes of subsystems / components typically only represent typical systems like traction or braking systems, and can only connect to the controller portion of the subsystem / component. For the peripheral parts of the subsystem / component (excluding the controller), the cost of simulation or physical connection is too high, and it's difficult to cover all subsystems / components of all existing vehicle models. Therefore, on-site testing and verification can only be performed after the entire vehicle is assembled, which puts pressure on the development cycle and cost of new rail transit equipment.

[0058] Furthermore, the design verification of control functions for subsystems / components is typically handled independently by the subsystem supplier, who builds the simulation platform. These subsystem simulation platforms often employ hardware-in-the-loop (HIL) simulation methods and generally include the subsystem controller, peripheral simulation models, and host computer interface software. However, manually setting trigger conditions and managing tests through the host computer interface cannot realistically and completely simulate the operation of the actual vehicle, resulting in low testing efficiency and low operational coverage. Moreover, because the system is tested in isolation, it is impossible to verify the interface functions with the vehicle's control circuits and control systems in advance, making it impossible to avoid modifications needed due to problems arising during the actual vehicle debugging and verification process.

[0059] To address the aforementioned issues, this application provides a method for verifying train control functions, enabling the train subsystem to fully participate in the overall train testing, thereby increasing test coverage and better realizing the verification of overall train control functions.

[0060] Figure 1 This is a schematic diagram of a subsystem simulation system integration scheme provided in an embodiment of this application. Figure 1 As shown, the subsystem simulation system is located at the subsystem supplier's premises and is built by the supplier. Since train subsystems are generally represented by typical systems such as traction or braking systems, the corresponding subsystem simulation system is used to simulate these systems. The main simulation system is located at the train's main manufacturer and is used to simulate the entire vehicle's control circuitry. The main simulation system includes a user interface, control circuit models, and test cases, enabling whole-vehicle-level simulation.

[0061] In this embodiment, the subsystem simulation system is equipped with a communication interface and establishes a communication connection with the main simulation system through this interface. This communication connection allows the main simulation system to remotely control the subsystem simulation system by converting the subsystem's communication protocols and hardware signals into simulation data, enabling remote access and sending interactive interface configuration files for display in the main simulation system. It is understood that multiple subsystem simulation systems can exist, provided by a single subsystem vendor or by multiple subsystem vendors.

[0062] Figure 2 A flowchart illustrating a train control function verification method provided in this application embodiment. The method is applied to a subsystem simulation system; such as... Figure 2 As shown, the method includes:

[0063] S10: Control commands for monitoring the main simulation system.

[0064] In practice, after the subsystem simulation system establishes a communication connection with the main simulation system, it monitors the control commands of the main simulation system. It is understood that the main simulation system's control commands can include commands to start the simulation, commands to end the simulation, and commands to disconnect the communication connection; the subsystem simulation system can respond to all of these commands.

[0065] S11: When a control command to start the simulation is received, the subsystem simulation data is collected.

[0066] When the subsystem simulation system receives a control command indicating that the simulation has started, it begins the simulation and simultaneously collects its own subsystem simulation data. It is understood that the subsystem simulation data includes the configuration parameters and corresponding variable values ​​of each parameter used by the subsystem simulation system during the simulation of the subsystem. This embodiment does not limit the specific content of the subsystem simulation data; it depends on the specific implementation.

[0067] It should be noted that in specific implementations, the acquisition of subsystem simulation data can be done in real time or according to a preset period. This embodiment does not impose any restrictions and depends on the specific implementation situation.

[0068] S12: Generate a combined data package containing subsystem simulation data based on the subsystem input / output configuration.

[0069] Furthermore, the subsystem input / output configuration of the subsystem simulation system is obtained. The subsystem input / output configuration represents the relevant configurations for communication between the subsystem simulation system and the main simulation system, including at least the configuration of the communication protocol and the communication interface. Based on the subsystem input / output configuration, a combined data packet containing the subsystem simulation data is generated, which can be sent from the subsystem simulation system to the main simulation system.

[0070] S13: Send the combined data packet to the main simulation system so that the main simulation system can update the current value of the corresponding variable based on the data in the combined data packet; return to step S11.

[0071] Finally, the combined data packet is sent to the main simulation system. It is understood that the combined data packet contains subsystem simulation data from the subsystem simulation system. The main simulation system can update the current values ​​of the corresponding variables in the main simulation system based on the subsystem simulation data, thereby completing the simulation. Then, return to step S11 to collect subsystem simulation data again.

[0072] Furthermore, both the subsystem simulation system and the main simulation system have interactive interfaces. These interfaces display various system configurations and variable values, and allow for editing and modification of these configurations and variable values. Correspondingly, when the main simulation system acquires subsystem simulation data, it can display the data through the interactive interface.

[0073] In this embodiment, the train control function verification method is applied to a subsystem simulation system. The subsystem simulation system is equipped with a communication interface and establishes a communication connection with the main simulation system through the communication interface. Specifically, it monitors the control commands of the main simulation system; when a control command indicating the start of simulation is received, it collects subsystem simulation data; it generates a combined data packet containing subsystem simulation data according to the subsystem input / output configuration; it sends the combined data packet to the main simulation system so that the main simulation system can update the current value of the corresponding variable according to the data in the combined data packet; and it returns to the step of collecting subsystem simulation data. Therefore, the above scheme, by setting up a communication interface in the subsystem simulation system, realizes remote access of the subsystem simulation system to the main simulation system, which serves as the simulation platform for the train's overall control function. Based on this, under the control of the main simulation system, the subsystem simulation data is sent to the main simulation system, realizing remote collaborative simulation testing with the train's overall control function simulation platform. This improves the efficiency of the integrated testing and verification of the overall vehicle control function, and enhances the completeness and effectiveness of the test, while also saving costs compared to traditional semi-physical testing.

[0074] In order to receive simulation data from the main simulation system and modify variable values ​​in the subsystem simulation system, based on the above embodiments, as a preferred embodiment, when a control command indicating the start of simulation is received, the following is also included:

[0075] S14: Receive simulation data sent by the main simulation system.

[0076] S15: Analyze simulation data based on the subsystem input / output configuration.

[0077] S16: Update the corresponding variable values ​​based on the parsed simulation data, and return to step S14.

[0078] Among them, the variable values ​​are the parameter variable values ​​of the subsystem simulation system during the simulation process.

[0079] In practice, when the subsystem simulation system receives a control command indicating the start of simulation, the subsystem simulation system initiates its own simulation process, and the main simulation system also initiates its own simulation process. The main simulation system receives a combined data packet containing the subsystem simulation data sent by the subsystem simulation system, and simultaneously sends data to the subsystem simulation system.

[0080] Specifically, the subsystem simulation system receives simulation data sent by the main simulation system. This can be understood as the simulation data sent by the main simulation system representing new variable values ​​generated during the simulation process to update relevant variables in the subsystem simulation system. Upon receiving the simulation data, the subsystem simulation system parses it according to its input / output configuration; it then updates the corresponding variable values ​​based on the parsed simulation data, thus enabling the main simulation system to control the subsystem simulation system. Finally, it returns to the step of receiving simulation data from the main simulation system, thereby continuously updating the variable values ​​of the subsystem simulation system.

[0081] In this embodiment, when a control command representing the start of simulation is received, simulation data sent by the main simulation system is received; the simulation data is parsed according to the subsystem input / output configuration; and the corresponding variable values ​​are updated according to the parsed simulation data, thereby realizing the control and variable update of the subsystem simulation system by the main simulation system.

[0082] To ensure that the main simulation system is aware of the subsystem simulation system's configuration and interface display before starting the simulation, as a preferred embodiment, before monitoring the main simulation system's control commands and after establishing a communication connection with the main simulation system, the following steps are also included:

[0083] S17: Send the subsystem basic data configuration and subsystem interactive interface files to the main simulation system.

[0084] Specifically, after establishing a communication connection with the main simulation system, the subsystem simulation system sends the subsystem basic data configuration and the subsystem interactive interface file to the main simulation system. This allows the main simulation system to obtain the various data configurations of the current subsystem simulation system and display the various data configurations of the subsystem according to the subsystem interactive interface file, thereby realizing full data display of the main simulation system during the vehicle control function test.

[0085] Furthermore, to allow users to edit the interactive interface of the subsystem simulation system, and to ensure that the main simulation system is aware of the edited interactive interface, as a preferred embodiment, before monitoring the control commands of the main simulation system, and after sending the subsystem basic data configuration and the subsystem interactive interface file to the main simulation system, the following steps are also included:

[0086] S18: After the user edits the subsystem interface, a new subsystem interface file is generated;

[0087] S19: Send the new subsystem interactive interface file to the main simulation system;

[0088] The subsystem's interactive interface file contains page properties and control properties.

[0089] In practice, users can edit the interactive interface of the subsystem simulation system at any time. After editing, a new subsystem interactive interface file is generated. If a communication connection has been established with the main simulation system, the new subsystem interactive interface file is sent to the main simulation system; otherwise, it is sent after the communication connection is established. In this embodiment, the format of the subsystem interactive interface file is not limited and depends on the specific implementation. Preferably, Extensible Markup Language (XML) format can be selected.

[0090] It is important to note that the subsystem interface file contains page properties and control properties. Page properties include information on page size and style; display control properties include control position, size, style, type, and bound variables. Control types primarily include control controls, display controls, icon controls, and container controls. Control controls include, but are not limited to, buttons, switches, and circuit breakers, each bound to a single variable; display controls include, but are not limited to, indicator lights, progress bars, dashboards, dials, and images, each bound to a single variable; chart controls include, but are not limited to, line charts, bar charts, pie charts, and list boxes, each potentially bound to multiple variables; container controls include, but are not limited to, label boxes, frames, and groups, with no variables bound to container components. In summary, the page properties and control properties in the subsystem interface file enable the subsystem simulation system and the main simulation system to display various parameter variables of the subsystem simulation system.

[0091] Furthermore, during the vehicle control function test simulation between the subsystem simulation system and the main simulation system, the user can control the entire simulation process. In specific implementation, this also includes:

[0092] S20: Monitors the user's command to close the emulation;

[0093] S21: When a simulation shutdown command is received, stop collecting simulation data from the subsystem.

[0094] In practical implementation, users can control the simulation process at any time while the subsystem simulation system receives and sends simulation data. It's important to note that the simulation process will continue running after startup until a user's command to shut it down is received. Therefore, in practical implementation, the system monitors for user commands to shut down the simulation; upon receiving such a command, it stops collecting subsystem simulation data, thus ending the current simulation process.

[0095] Figure 3 A flowchart illustrating another train control function verification method provided in this application embodiment. The method is applied to the main simulation system; such as... Figure 3 As shown, the method includes:

[0096] S30: Send the control command to the subsystem simulation system to start the simulation.

[0097] S31: Receive a combined data packet containing subsystem simulation data sent by the subsystem simulation system.

[0098] S32: Parse the combined data packet according to the subsystem input / output configuration to obtain the data in the combined data packet.

[0099] S33: Update the current value of the corresponding variable based on the data in the combined data packet; return to step S31.

[0100] In practice, the main simulation system first establishes a communication connection with the subsystem simulation system through a communication interface set on the subsystem simulation system. When the vehicle control function test begins, a control command indicating the start of the simulation is sent to the subsystem simulation system. At this time, the subsystem simulation system will collect subsystem simulation data and further send a combined data packet containing the subsystem simulation data to the main simulation system. The main simulation system receives the combined data packet containing the subsystem simulation data sent by the subsystem simulation system, and further parses the combined data packet according to the subsystem input / output configuration to obtain the data in the combined data packet. Finally, the main simulation system updates the current value of the corresponding variable according to the data in the combined data packet; it then returns to the step of receiving the combined data packet containing the subsystem simulation data sent by the subsystem simulation system to re-receive the subsystem simulation data. In this way, remote collaborative simulation testing of the entire vehicle is realized.

[0101] Since the variable values ​​of the subsystem simulation system need to be modified during the simulation process, the simulation data itself also needs to be sent to the subsystem simulation system during the simulation process.

[0102] S34: Collect simulation data.

[0103] S35: Generate a combined data package containing simulation data based on the subsystem input / output configuration.

[0104] S36: Send the combined data packet to the subsystem simulation system and return to step S34.

[0105] Furthermore, in order to ensure that the main simulation system is aware of the configuration and interface display of the subsystem simulation system before starting the simulation, the following steps are also included after establishing a communication connection with the subsystem simulation system and before sending the control command indicating the start of the simulation to the subsystem simulation system:

[0106] S37: Receive the basic data configuration and interactive interface files of the subsystem sent by the subsystem simulation system.

[0107] Furthermore, during the vehicle control function test simulation between the subsystem simulation system and the main simulation system, the user can control the entire simulation process:

[0108] S38: Monitor the user's command to close the emulation.

[0109] S39: When a simulation shutdown command is received, stop collecting simulation data.

[0110] In addition, to better understand the entire remote collaborative simulation testing process, the main simulation system also includes a simulation variable pool, through which simulation data is synchronized to the processing thread using a subscription / publishing method.

[0111] Specifically, when a user opens the interactive interface of the main simulation system, the interface configuration file of the main simulation system is loaded, interactive controls and the interface are displayed, and all control management variables are subscribed to. When the user clicks a control, the bound variable value is updated according to the internal logic of the control; when the subscribed variable value changes, the corresponding control state is updated. It should be noted that the update of the control state can be set by the user; it can be set to real-time update or to update at preset time intervals, depending on the specific implementation. For example, chart controls can use a periodic query method to update their display.

[0112] In the above embodiments, the train control function verification method has been described in detail. This application also provides embodiments of the train control function verification device.

[0113] Figure 4 This is a schematic diagram of a train control function verification device provided in an embodiment of this application. The device is applied to a subsystem simulation system; the subsystem simulation system is equipped with a communication interface and establishes a communication connection with the main simulation system through the communication interface; such as Figure 4 As shown, the device includes:

[0114] Monitoring module 10 is used to monitor the control commands of the main simulation system.

[0115] The acquisition module 11 is used to acquire subsystem simulation data when a control command indicating the start of simulation is received.

[0116] The generation module 12 is used to generate a combined data package containing subsystem simulation data based on the subsystem input and output configuration.

[0117] The first sending module 13 is used to send a combined data packet to the main simulation system so that the main simulation system can update the current value of the corresponding variable according to the data in the combined data packet; and trigger the acquisition module.

[0118] In this embodiment, the train control function verification device is applied to the subsystem simulation system, and during operation, it can implement all the steps of the train control function verification method applied to the subsystem simulation system. Specifically, it monitors the control commands of the main simulation system; when a control command indicating the start of simulation is received, it collects subsystem simulation data; it generates a combined data packet containing subsystem simulation data according to the subsystem input / output configuration; it sends the combined data packet to the main simulation system so that the main simulation system can update the current value of the corresponding variable according to the data in the combined data packet; and it returns to the step of collecting subsystem simulation data. Therefore, the above scheme, by setting a communication interface in the subsystem simulation system, realizes remote access of the subsystem simulation system to the main simulation system, which serves as the simulation platform for the train's overall control function. Based on this, under the control of the main simulation system, it sends subsystem simulation data to the main simulation system, realizing remote collaborative simulation testing with the train's overall control function simulation platform. This improves the efficiency of the integrated testing and verification of the overall vehicle control function, and enhances the completeness and effectiveness of the test, while also saving costs compared to traditional semi-physical testing.

[0121] The receiving module 15 is used to receive a combined data packet containing subsystem simulation data sent by the subsystem simulation system.

[0122] The parsing module 16 is used to parse the combined data packet according to the subsystem input / output configuration in order to obtain the data in the combined data packet.

[0123] Update module 17 is used to update the current value of the corresponding variable based on the data in the combined data packet; trigger the receiving module.

[0124] In this embodiment, the train control function verification device is applied to the main simulation system, and during operation, it can implement all the steps of the train control function verification method applied to the main simulation system. Specifically, it sends a control command representing the start of the simulation to the subsystem simulation system; receives a combined data packet containing subsystem simulation data sent by the subsystem simulation system; parses the combined data packet according to the subsystem input / output configuration to obtain the data in the combined data packet; updates the current value of the corresponding variable according to the data in the combined data packet; and returns to the steps of receiving the combined data packet containing subsystem simulation data sent by the subsystem simulation system. Therefore, the above scheme, by setting a communication interface in the subsystem simulation system, realizes remote access of the subsystem simulation system to the main simulation system, which serves as the simulation platform for the train's overall control function. Based on this, under the control of the main simulation system, the subsystem simulation data is sent to the main simulation system, realizing remote collaborative simulation testing with the train's overall control function simulation platform. This improves the efficiency of the integrated testing and verification of the overall vehicle control function, and enhances the completeness and effectiveness of the test, while also saving costs compared to traditional semi-physical testing.
