[0041] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the protection scope of the present application.

[0042] The core of the present application is to provide a method, device, medium and rail vehicle for drawing an interface of a train display, which is used to improve the interface development efficiency of the train display.

[0043] In order to enable those skilled in the art to better understand the solution of the present application, the present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0044] Figure 1 For the flowchart of a method for drawing an interface of a train display provided by the present application, as Figure 1 shown, the method includes:

[0045] S1: Receive a first operation instruction input by a user, and obtain an interface configuration file corresponding to the first operation instruction; wherein, each interface configuration file includes the variable names of all variables of a train.

[0046] In specific implementation, the user can input a first operation instruction through an operation in the interface management center. The interface management center can pull up a corresponding interface logic processing program, that is, a script language (QML) program, according to the first operation instruction. The QML program can obtain a corresponding interface configuration file from the configuration file center according to the first operation instruction input by the user.

[0047] The configuration file center stores a network data parsing configuration file and multiple interface configuration files. Each interface configuration file contains the variable names of all variables of a train, such as the variable names of variables like train speed, on / off state of the headlight, etc. The variable names contained in the interface configuration file obtained according to the first operation instruction are the variable names of the variables to be displayed on the interface. To facilitate interface drawing, the variables to be displayed can be two-dimensionally laid out in the interface configuration file according to the arrangement order of the variables to be displayed in the carriage interface. Specifically, taking the interface configuration file as an Excel-format file as an example, the number of rows of the interface configuration file can be used to represent the types of variables to be displayed, that is, each row of the interface configuration file represents a type of variable to be displayed, and the number of columns of the interface configuration file represents the formation number of the train, that is, each column of the interface configuration file represents a carriage of the train. After obtaining the values of the variables to be displayed, the values of the variables to be displayed in each carriage can be correspondingly filled into the interface configuration file according to the formation of the train and the variable names of the variables to be displayed, and the order of the values of the variables to be displayed in each column can be adjusted according to the arrangement order of the variables to be displayed in the carriage interface, so that the values of the variables to be displayed in each column of the interface configuration file are all arranged in the arrangement order of the variables to be displayed in the carriage interface. It should be noted that in specific implementation, the interface configuration file can be an Excel-format file or a Word-format file, and this embodiment does not limit the format of the interface configuration file.

[0048] S2: Obtain the values of the variables to be displayed according to the interface configuration file and the network data parsing configuration file; wherein, the network data parsing configuration file includes the variable names of all variables of trains of multiple models and the port offsets corresponding to each variable.

[0049] To facilitate querying the corresponding port offset according to the variable name, the variable name of each variable in the network data parsing configuration file can be concatenated or combined with the port offset corresponding to the variable, so that the corresponding port offset can be directly found from the network data parsing configuration file according to the variable name. In specific implementation, the data, that is, the values of the variables to be displayed, can be obtained from the data center according to the port offsets corresponding to the same-name variables in the network data parsing configuration file and the interface configuration file, and then the obtained values of the variables to be displayed are correspondingly filled into the interface configuration file according to the variable names of the variables to be displayed in the interface configuration file, and the order of each variable to be displayed is adjusted according to the arrangement order of the variables to be displayed in the carriage interface. It can be understood that both the network data parsing configuration file and the interface configuration file are files pre-filled by the user. Due to the complexity of train models, the user can fill the variable names of all variables in the train of the corresponding model and the port offsets corresponding to each variable in the data center into the network data parsing configuration file as long as the network data parsing configuration file includes the variable names of all variables in all interface configuration files.

[0050] S3: Call the pre-created C++ base class to process the value of the variable to be displayed to obtain a data processing result, and draw the car interface according to the data processing result; wherein, the C++ base class is created according to the common data processing logic of each car, and the data processing result is a variable-length data packet in a fixed format.

[0051] The C++ base class is a mathematical model created according to the common data processing logic of each car obtained by summarizing the commonalities of the train display interface. All interfaces are derived from this C++ base class to implement a set of mathematical models shared by all interfaces. In a specific implementation, after filling the value of the variable to be displayed into the interface configuration file, the factory pattern in the design pattern can be used to uniformly manage the instantiated objects of the C++ base class in the actual car forms such as motor cars and trailers, and the C++ base class is used to process the value of the variable to be displayed to obtain a data processing result, and then the data processing result is returned to the QML program so that the QML program can draw the interface according to the data processing result. Specifically, to facilitate adding the value of the variable to be displayed to the data packet subsequently, the value of the variable to be displayed in each car can be encapsulated into a variable-length data packet to obtain the data processing result, thus realizing the variable-length design of the logical processing; after receiving the variable-length data packet, the QML program can draw the interface of the train display by synthesizing the data in the data packet.

[0052] This embodiment provides a method for drawing the interface of a train display, including receiving a first operation instruction input by a user and obtaining an interface configuration file corresponding to the first operation instruction; wherein, each interface configuration file includes the variable names of all variables of a train; obtaining the value of the variable to be displayed according to the interface configuration file and the network data parsing configuration file; wherein, the network data parsing configuration file includes the variable names of all variables of trains of multiple vehicle types and the port offsets corresponding to each variable; calling the pre-created C++ base class to process the value of the variable to be displayed to obtain a data processing result, and drawing the car interface according to the data processing result; wherein, the C++ base class is created according to the common data processing logic of each car, and the data processing result is a variable-length data packet in a fixed format. It can be seen that in the context of a complex train vehicle type, this method can obtain the value of the variable to be displayed of trains of different vehicle types by replacing the interface configuration file. In addition, this method integrates the common data processing logic of each car into the C++ base class. Therefore, when developing a new interface, there is no need to re-determine the data processing logic, effectively reducing the repetitive work when developing a new interface. And since the data processing result of the C++ base class is a variable-length data packet in a fixed format, the data processing result can be transmitted according to a standardized interface, and there is no need to re-determine the data interface, further improving the interface development efficiency of the train display.

[0053] Based on the above embodiment, this embodiment provides a preferred implementation manner for obtaining the value of the variable to be displayed. This step includes:

[0054] Take the variables with the same name in the interface configuration file and the network data parsing configuration file as the variables to be displayed, and obtain the values of the variables to be displayed from the data center according to the port offsets corresponding to the variables to be displayed; wherein, the data center includes Ethernet data and MVB data.

[0055] In this embodiment, the data center is used to store Ethernet data and Multifunction Vehicle Bus (MVB) data. It should be noted that for the convenience of obtaining data from the data center, the Ethernet data and MVB data in the data center can be formatted so that data can be obtained from the data center through a standardized interface.

[0056] Based on the above embodiment, this embodiment provides another preferred implementation manner for obtaining the values of the variables to be displayed. This step includes:

[0057] Use the network data parsing configuration file to parse the data in the data center to obtain the correspondence between each variable name in the network data parsing configuration file and the data in the data center;

[0058] Obtain the values of the variables to be displayed according to each variable name and the correspondence in the interface configuration file.

[0059] Specifically, the corresponding variable values can be found in the data center using the port offsets in the network data parsing configuration file. Since each port offset corresponds to each variable name in the network data parsing configuration file, a correspondence between each variable name and each variable value can be established. Therefore, after obtaining the interface configuration file, the variable values corresponding to each variable name in the interface configuration file can be obtained according to each variable name in the interface configuration file and the correspondence between each variable name and each variable value.

[0060] Based on the above embodiment, for the convenience of drawing the carriage interface, it is necessary to call the pre-created C++ base class and the derived class of the C++ base class to process the obtained values of the variables to be displayed. This step includes:

[0061] Use the C++ base class to perform a primary processing on the values of the variables to be displayed, and use the derived class of the C++ base class to perform a secondary processing on the values of the variables to be displayed after the primary processing to obtain a data processing result.

[0062] In this embodiment, the obtained values of variables to be displayed can be encapsulated by a C++ base class for one-time processing, and then the encapsulated values of variables to be displayed can be further processed by a derived class of the C++ base class. The secondary processing methods include, but are not limited to, flipping, arithmetic operations, etc. To facilitate the distinction of the values of variables to be displayed in each carriage, it is assumed that the number of columns in the interface configuration file represents the formation number of the train. After the values of variables to be displayed are correspondingly filled into the interface configuration file, each column of data in the interface configuration file can be encapsulated, so as to realize the data encapsulation for each carriage.

[0063] It should be noted that in the specific implementation, variable-length data structures such as QMap and QList in the application development framework (Qt) can be relied on to encapsulate the carriages, and the processing method of secondary processing can be selected according to the user's needs, so as to obtain the data processing result, that is, a variable-length data packet in a fixed format.

[0064] On the basis of the above embodiment, to facilitate the drawing of the carriage interface, parameters such as the train type and the number of carriages need to be determined. This embodiment makes a supplementary description of the steps for drawing the carriage interface based on this. The steps include:

[0065] Determine the number of carriages according to the data length of the data processing result, and determine the train type according to the data flag bit of the data processing result;

[0066] Determine the arrangement order of the variables to be displayed in the carriage interface according to the interface configuration file;

[0067] Draw the carriage interface of the train corresponding to the interface configuration file through the number of carriages, the train type, the data processing result, and the arrangement order of the variables to be displayed in the carriage interface.

[0068] Specifically, it is assumed that the number of columns in the interface configuration file represents the formation number of the train, and the one-time processing method of the C++ base class is to encapsulate each column of data in the interface configuration file. Then the data length of the data processing result represents the number of carriages. Therefore, the number of carriages can be determined according to the data length of the data processing result, and the train type can be determined according to the encapsulated data flag bit, such as a motor car or a trailer. In addition, the arrangement order of the variables to be displayed in the interface of each carriage can be determined according to the arrangement order of each column of data in the interface configuration file. Thus, the corresponding carriage interface can be drawn through the number of carriages, the train type, the values of the variables to be displayed, and the arrangement order of the variables to be displayed in the carriage interface.

[0069] It should be noted that to improve the design efficiency of the car body interface, all variables to be displayed in the interface of each car body can be statistically summarized according to the principle of the most comprehensive listing, so as to draw a car body with the most complete data as the basic car body, and copy the basic car body according to the number of car bodies to use the basic car body as the template for each car body. Then, the QML program processes each basic car body according to the variable values to be displayed in each car body and the arrangement order of the variables to be displayed in the car body interface, and the display interfaces of each car body can be obtained.

[0070] On the basis of the above embodiments, to facilitate the user to learn about the drawn car body interface, after the QML program draws the car body interface according to the data processing result in this embodiment, it further includes: displaying the car body interface.

[0071] In specific implementation, it can be uniformly displayed after all interfaces are drawn, or each car body interface can be displayed after it is drawn. This embodiment does not limit this. In addition, for the convenience of the user to query, the display method can be set to display each car body interface one by one in a certain order. For example, the car body interfaces are displayed in the car body order.

[0072] After the car body interface is drawn in this embodiment, the train status is displayed by displaying the car body interface, so that the user can learn about the train status.

[0073] On the basis of the above embodiments, to facilitate the user to modify the drawn interface, after the car body interface is displayed in this embodiment, the drawn interface is modified according to the user operation. This step includes:

[0074] Receiving a second operation instruction input by the user, and modifying the interface configuration file according to the second operation instruction;

[0075] Obtaining target variable values to be displayed according to the modified interface configuration file and the network data parsing configuration file;

[0076] Invoking the C++ base class to process the target variable values to be displayed to obtain a target data processing result, and changing the car body interface according to the target data processing result.

[0077] In specific implementation, the user can modify the interface configuration file through the input second operation instruction. For example, the variable values to be displayed are added or deleted, the variable values to be displayed are modified, and the arrangement order of the variable values to be displayed in the interface configuration file is modified. After the interface configuration file is modified, the variable values to be displayed, that is, the target variable values to be displayed, can be re-obtained according to the network data parsing configuration file and the modified interface configuration file, and then the target variable values to be displayed are correspondingly filled into the modified interface configuration file. The C++ base class processes the target variable values to be displayed filled into the modified interface configuration file to obtain a target data processing result, and further changes the car body interface according to the target data processing result.

[0078] After presenting the car body interface in this embodiment, the drawn car body interface is changed according to user requirements to control the train status according to user requirements.

[0079] In the above embodiment, the method for drawing the interface of the train display is described in detail. The present application also provides an embodiment corresponding to the device for drawing the interface of the train display. It should be noted that the present application describes the embodiments of the device part from two perspectives, one is from the perspective of functional modules, and the other is from the perspective of hardware.

It can be seen that this device can obtain the variable values to be displayed of trains of different vehicle types by replacing the interface configuration file.

And because the data processing result of the C++ base class is a variable-length data packet in a fixed format, the data processing result can be transmitted according to a standardized interface without re-determining the data interface, further improving the interface development efficiency of the train display.
