It will be apparent to one of ordinary skill in the art that the present application may be practiced without these specific details. In other instances, well-known processes have not been described in detail so as not to obscure the description of the embodiments of the present application with unnecessary detail. Thus, the present application is not intended to be limited to the embodiments shown, but is to be accorded the widest scope consistent with the principles and features disclosed in the embodiments of the present application.

Embodiments of the present application provide a model processing method, an apparatus, a terminal device, and a storage medium, which will be described in detail below.

Referring to fig. 1, fig. 1 is a flowchart of a model processing method according to an embodiment of the present application, including the following steps:

101. in a plurality of simulation models of the HIL system, a target simulation model needing port connection and a data port available for connection in the target simulation model are determined.

The embodiment of the application aims at port connection of simulation models in an HIL system, and can be port connection of ports between the simulation models or port connection of ports between the same simulation model. The HIL system comprises a plurality of simulation models, and the simulation models needing port connection are used as target simulation models so as to realize the port connection of the target simulation models. The target simulation model can work on an upper computer, can also work on a simulation board card, and can also work on any equipment of the HIL system.

In some embodiments of the application, a target simulation model to be subjected to port connection is determined, and the target simulation model may be determined according to conditions such as a scene creation requirement and a scene creation specification. Before a target simulation model needing port connection is determined, a simulation model to be contained in a scene and a model type of the simulation model are determined according to scene creation requirements, a JSON file with unconfigured parameters corresponding to the simulation model is determined according to the model type, and the JSON file is subjected to parameter configuration according to the scene requirements and functional requirements of the simulation model to obtain the JSON file with the parameter configuration completed. After the JSON file with the parameter configuration completed is subjected to mutation, compilation and other processing, a model instance of a corresponding simulation model can be generated, that is, a simulation model in a final model file corresponding to the model instance can be obtained, and the simulation model in the final model file can include at least one of the following:

an analog input model, an analog output model, a digital input model, a digital output model, a PWM input model, a PWM output model, a CAN model, a LIN model, a timer model, a presenter model, a sensor model, a BSU model, a BMS model, and the like.

It can be seen that the simulation model may be an environmental channel model, which may be a Simulink model, a generic model, or other custom model.

After a specific simulation model is generated, when port connection between the simulation models is performed or when connection between ports of the simulation models themselves is performed, a target simulation model for performing port connection is determined as necessary. After the target simulation model is determined, a final model file corresponding to the target simulation model is acquired from a database or a disk of the HIL system through a preset incidence relation, or the final model file corresponding to the target simulation model is acquired from the database or the disk connected with the HIL system. The final model file may record information corresponding to the target simulation model, including model characteristics, data port, port description information, and the like. Furthermore, the information such as the port description information may also be derived from a model description file describing the simulation model, and further, the information described by the model description file at least includes the data port and the port description information, and may also include model characteristics and the like.

Optionally, in some embodiments, step 101 includes:

101a: obtaining a model description file of the target simulation model, compiling the model description file to generate a final model file corresponding to a model instance of the target simulation model,

101b: importing the final model file into a connection tool for file reading;

101c: and displaying the data port and the frame tool corresponding to the data port on a display interface of the connection tool based on the file reading result.

101a may be executed at any time, for example, a final model file may be generated in advance for each simulation model, where the final model file of the target simulation model is naturally included, and then the final model file may be generated by processing such as compiling before the target simulation model is determined, and then the final model file of the target simulation model is imported into the connection tool after the target simulation model is determined; in some examples, the final model file may be generated after determining which simulation model and which simulation model the target simulation model is.

The execution of 101b may be performed at any time after 101a, for example, after generating the final model file, the final model file may be imported into the connection tool for reading, but only when the target simulation model is determined and the connection relationship needs to be established, the execution of 101c is performed in response to the operation of the user, and the corresponding data port and frame are displayed.

Because the model description file has predefined and recorded the relevant information of the data port of the target simulation model, after compiling the model description file to obtain the corresponding final model file, reading the file of the final model file through the connection tool, and generating the corresponding frame, wherein the frame can display the included data port and the port name of each data port and/or the display name of the data port on the display interface of the connection tool, which is also recorded in the result of reading the file.

As shown in fig. 2, the frame in the embodiment of the present application is used to describe the setting manner of the data ports included in the model description file and the final model file, and the setting manner includes the port direction, the position of the port relative to the frame, the port number of the data ports, the port function, and the like. These can also be understood as the result of a file read.

It should be noted that the schematic structural diagram of the frame shown in fig. 2 is only an example provided in the embodiment of the present application, and the structure of the frame is not limited to the structure shown in fig. 2. In other embodiments, the structure of the frame may be altered.

Optionally, the connection tool is a connection setter, and is a tool for connecting data ports on the framework corresponding to the target simulation model. After the final model file is imported into the connection tool, the corresponding frame tool can be determined through reading the file, and the frame tool is displayed on the display interface, so that port connection is realized through operation on the display interface.

If the number of the target simulation models for port connection is one, importing the final model file corresponding to the target simulation model into the connection tool, and displaying a frame corresponding to the imported final model file on a display interface of the connection tool. The port connection is realized by the connection operation of the data port of the frame on the display interface.

If the number of the target simulation models for port connection is multiple, the final model file corresponding to each target simulation model is imported into the connection tool, and the frame corresponding to each final model file is displayed on the display interface of the connection tool. The connection of the ports is realized through the connection operation of the data ports of the frames or between the frames on the display interface, and the connection between the target simulation models is realized.

102. And determining target data ports in the data ports, and acquiring port description information of each target data port.

Data ports include input ports, output ports, and other types of functional data ports. In the embodiment of the present application, the port connection between the output port and the input port is mainly based on, and the target data port at least includes one target output port and at least one target input port, and the port connection between the target data ports is performed by using the target output port to point to the target input port.

Optionally, the included data port may be known through the structure of the frame, and the port description information corresponding to the data port may be displayed by clicking the data port on the frame.

For example, a frame displayed on the display interface includes an input port and an output port, and by clicking the position of the input port on the frame, the position on the display interface corresponding to the input port displays the port description information of the input port in a small window manner.

For example, a frame displayed on the display interface includes an input port and an output port, and by clicking the position of the output port on the frame, the display interface is switched to a corresponding interface displaying the port description information, and the port description information of the input port is displayed on the interface.

After the frame tool is displayed on the display interface of the connection tool, the contained data port can be known through the structure of the frame tool. However, when performing port connection, not all data ports on the frame need to be port-connected, but a data port that needs to be port-connected is determined from the data ports as a target data port according to a scene creation requirement and a port function of the data port, and the target data port may be port-connected.

And if the data ports of the frame are determined to be only needed to be subjected to port connection according to the scene creation requirement and the port functions of the data ports, taking the data ports determined on the frame as target data ports to be subjected to port connection. And if the situation that all the data ports of the frame are subjected to port connection is determined according to the scene creation requirement and the port function of each data port, taking all the data ports on the frame as target data ports to perform port connection.

Optionally, in an embodiment of the present application, the port description information includes a port name, a byte order, an item number, a display name on a display interface, a port type, a queue attribute, a structure attribute, a port direction, path information, and the like.

As shown in table 1 below, table 1 below is an example of port description information:

port name	AOUT[0]
		Byte order	LSBfirst
Number of items	1
		Display name	AOUT[0]
Port type	Double
		Whether to queue or not	False
Whether structure is	False
		Direction of port	Input
Route(s)	InputPort/AOUT[0]

TABLE 1

The byte order describes whether the sequence during storage and the sequence during input (output) are first-come first or last-come first, the item number describes the set number of the target data port in the corresponding frame, whether the queue describes whether the target data port has a queue attribute or not, whether the structure describes whether the target data port has a structure attribute or not, and the port type describes the type of the target data port. It should be noted that in other embodiments, the port description information may be set separately.

Optionally, the port type of the target data port (i.e., the data type of the data transmitted by the target data port) may include an Int type, a Uint type, a Float type, a Double type, a Same struct type, a Diff struct type, and so on.

103. And determining the connection relation between the target data ports according to the port description information and a preset port connection rule so as to transmit signals based on the connection relation when the target simulation model works.

After the connection relation between the target data ports of the target simulation model is determined, the target data ports with the connection relation are subjected to port connection, namely the target data ports of the target simulation model are subjected to port connection, or the target data ports of the target simulation model are subjected to port connection with the target data ports of other target simulation models.

For example, it is determined that one target simulation model requiring port connection is used, and it is determined that the target simulation model includes two target data ports, where the two target data ports are a target output port and a target input port, respectively, and then the target output port and the target input port are subjected to port connection to implement data transmission.

For example, it is determined that the target simulation model requiring port connection includes a first target simulation model and a second target simulation model, a target data port of the first target simulation model is determined to be a first target data port, a target data port of the second target simulation model is determined to be a second target data port, the first target data port is a target output port, and the second target data port is a target input port. The target output port and the target input port are subjected to port connection to realize data transmission and realize connection between the simulation model and the simulation model.

In the embodiment of the application, the port connection rule is preset, and when the port connection is performed, the port connection rule is combined to implement the port connection.

A port connection rule, which is understood to be a relationship between a result of defining whether or not a connection is allowed and/or recommended between ports and port description information; furthermore, any rule based on the port description information and based on whether the connection is allowed and/or recommended among the ports can be used as an implementation mode of the port connection rule;

port description information, which may be understood as any information describing a corresponding port; for example, may include information describing or embodying at least one of:

the data type of the data transmitted by the corresponding data port;

the data transmission direction of the corresponding data port;

whether the corresponding data port has a queue attribute (or can be understood as a queue identification);

whether the corresponding data port has a structural attribute; and the specific content of the structural attributes;

the structural attributes are used for characterizing: the data that can be transmitted by the corresponding target data port includes multiple sets of data that are transmitted in a specified order, each set of data having a corresponding data type.

As shown in table 2 below, table 2 below is a partial example of a port connection rule:

TABLE 2

As shown in table 2, defined in table 2 are collocation rules for different port types. Wherein "√" means connectable, as can be understood to allow connection, "! "indicates connectable but generates a warning, which is understood not to recommend connection, and" x "indicates not connectable, which is understood not to allow connection.

Optionally, in some embodiments, step 103 includes: and responding to the connection operation of the target data port on the display interface, forming the connection relation, and determining that the connection relation and the port description information meet the port connection rule.

The target data port having the connection relationship may be a connection between the data port and the data port of the frame corresponding to one target simulation model, or a connection between data ports of frames corresponding to a plurality of target simulation models.

As shown in fig. 3, illustrated in fig. 3 is a connection between target data ports between two chassis to show the connection of the two chassis.

For example, the target simulation model to be subjected to port connection includes a first target simulation model and a second target simulation model, and it is determined that a connection relationship exists between a first target data port of the first target simulation model and a second target data port of the second target simulation model, and the first target data port is a target output port and the second target data port is a target input port. After the frames corresponding to the two target simulation models are displayed on a display interface of the connection tool, the first target data port and the second target data port are connected in a connection operation mode on the display interface, and port connection between the target output port and the target input port is achieved.

Due to the limitation of the preset port connection rule, the operation results of correct connection, incapability of connecting, line connection warning and the like can occur after the connection operation is performed. If the operation result is warning line connection, corresponding prompt information is displayed on a display interface of the connection tool, and the content of the prompt information can be 'warning line connection and please check'.

Setting a display mode aiming at an operation result of the connection operation, for example, when the connection is correct, the connection line is displayed on a display interface, but prompt information cannot be displayed; when the warning line is connected, the display interface displays the connecting line, but can display prompt information; if the connection cannot be achieved, the display interface can automatically clear the invalid connection and display corresponding prompt information.

Under the condition that the warning line is connected and cannot be connected, besides displaying corresponding prompt information, automatic analysis can be performed according to corresponding port description information and port connection rules, and an analysis result is displayed on a display interface for a connecting person to refer.

Optionally, in some embodiments, step 103 includes: and according to the port description information, determining the data type and the data transmission direction of the data transmitted by the target data port, and according to the port connection rule, determining that the data types of the target data ports connected in the connection relation are the same and the data transmission directions are corresponding.

This process may be understood as an implementation manner of "determining that the connection relationship and the port description information satisfy the port connection rule", that is, "the data types are the same, and the data transmission direction corresponds to" being an essential condition or a necessary condition that the connection relationship and the port description information satisfy the port connection rule ".

In other embodiments, the process may also be understood as an implementation manner of automatically determining the connection relationship in step 103.

Wherein, the data transmission direction correspondence can be understood as: one of the two destination data ports connected is an input port and the other is an output port.

As shown in FIG. 3, FIG. 3 shows the structure of two frames, the frame on the left side is set as the first frame, the frame on the right side is set as the second frame, the first target data port on the first frame is AIN [2], and the second target data port on the second frame is AOUT [2]. When the first target data port and the second target data port have a connection relationship, the port direction of the first target data port in the drawing is the right side, and the port direction of the second target data port is the left side, then the port directions of the first target data port and the second target data port are corresponding, and the port types of the first target data port and the second target data port are the same and are both input and output ports.

Optionally, after determining the port type and the port direction, the port connection is performed in combination with the port connection rule. For example, if the first target data port AIN [2] shown in fig. 3 is an output port of Int8 and the second target data port AOUT [2] is an input port of Int16, the first target data port and the second target data port may be wired, and after the wiring operation is performed, the display is as shown in fig. 3, and the two target data ports in fig. 3 are connections from the output port to the input port.

Optionally, in some embodiments, step 103 includes: and determining whether the target data port has the queue attribute according to the port description information, and determining that the target data port which does not have the queue attribute and serves as the input port in the connection relation is connected with only one target data port according to the port connection rule.

This process may be understood as an implementation manner of "determining that the connection relationship and the port description information satisfy the port connection rule", that is, "a target data port having no queue attribute and serving as an input port is connected to only one target data port" is an essential condition or a necessary condition that "the connection relationship and the port description information satisfy the port connection rule".

Meanwhile, according to the port connection rule, the target data port which has queue attribute and is used as an input port in the connection relation can be connected with one target data port or a plurality of target data ports; in addition, generally speaking, an input port may be selectively configured to have queue attributes.

In some examples, the output port may not be configured, for example, a target data port as the output port may be connected to both one target data port and a plurality of target data ports. In other examples, the output port may also be selectively configured to have queue attributes,

the queue attribute may also be understood as a queue identifier for identifying whether a corresponding port allows to connect multiple target data ports, and further, may also be understood as: in the corresponding simulation model, whether a mechanism is designed is that: a mechanism for sequentially processing data input (or output) for different connected data ports based on the queue;

in some embodiments, the queue attribute may also be understood as a port connection mode for describing a data port, and after the target data port is determined, whether the target data port has the queue attribute may be known through port description information of the target data port. If so, performing port connection according to the queue attribute and the port connection rule. If not, the target data port determines that the port connection can be carried out in a one-to-one port connection mode.

For example, the target simulation model to be ported includes a first target simulation model including a first target data port, a second target simulation model including a second target data port, and a third target simulation model including a third target data port. The first target data port, the second target data port and the third target data port have a connection relation, wherein the first target data port is an output port, and the second target data port and the third target data port are input ports. If the first target data port has the queue attribute, the port connection mode corresponding to the queue attribute is one-to-many connection. Then, when port connection is performed according to the connection relationship, the first target data port is respectively connected with the second target data port and the third target data port.

For example, a target simulation model to be ported includes a first target simulation model including a first target data port and a second target simulation model including a second target data port. The first target data port and the second target data port have a connection relation, wherein the first target data port is an output port, and the second target data port is an input port. If the first target data port does not have the queue attribute, the port connection mode of the first target data port is one-to-one connection. Then, when port connection is performed according to the connection relationship, the first target data port and the second target data port are connected.

Optionally, in some embodiments, step 103 includes: and determining whether the target data port has the structural attribute and the attribute information of the structural attribute of the target data port according to the port description information, and determining that the structural attributes of the target data ports with the structural attribute connected in the connection relationship are the same according to a preset port connection rule.

This process may be understood as an implementation manner of "determining that the connection relationship and the port description information satisfy the port connection rule", that is, "the structural attribute of the target data port having the structural attribute connected in the connection relationship is the same" is an essential condition or a necessary condition that the connection relationship and the port description information satisfy the port connection rule ".

In other embodiments, the process may also be understood as an implementation manner of automatically determining the connection relationship in step 103. For example, after two simulation models needing to be connected are determined, data ports with the same structural attributes can be automatically connected together;

wherein the attribute information of the structural attribute is used for representing: the data that can be transmitted by the corresponding target data port includes multiple groups of data transmitted in a designated sequence, each group of data has a corresponding data type, and further, the data port with structural attributes is generally complex, and multiple groups of data of different data types need to be transmitted. In other words, for two data ports with completely identical attribute information of the structure attribute, the way of processing and writing data when the corresponding simulation model outputs data corresponds to the way of extracting and analyzing data when the corresponding simulation model receives data, that is: for any group of data, the simulation model writes and extracts the group of data in the same data bit, and performs the processing before the writing and the analysis after the extraction in the same data type processing mode.

The configuration attributes may also be understood to describe whether the corresponding target data port has a configuration. With respect to the definition of structure, it is understood that the structure comprises a plurality of members (i.e., each set of data for a given sequential transmission may be considered a member), each member having a corresponding data type. For example, one structure includes a group of Int8 data types of data, a group of Uint8 data types of data, and a group of Uint16 data types of data, and further, three groups of data need to be transmitted, and then the structure includes three members.

When the connection relationship between the target data ports with the structural attributes is determined, the target data ports with the connection relationship have the same structural attributes, and then the port connection can be carried out. The definition of the same structure attribute is that the name of the structure to which the target data port to be connected belongs, the number of ports of the structure to which the target data port to be connected belongs, the type of the ports of the structure to which the target data port to be connected belongs, and the sequence of the ports of the structure to which the target data port to be connected belongs are all the same.

Multiple types of structures can be predefined, and corresponding names are set for each type, so that when determining whether the structure attributes of the target data ports needing to be connected are the same, the structure names can be determined by judging the structure attributes.

In one embodiment, after two target simulation models to be connected are determined, if it is assumed that the two target simulation models are a fourth target simulation model and a fifth target simulation model, the target data port may also be determined by the following steps:

acquiring one or more historical connection records of a simulation model of a fourth target simulation model (namely a first simulation model) and a simulation model of a fifth target simulation model (namely a second simulation model); the historical connection record represents a connection relation which occurs in the past in a data port between the first type simulation model and the second type simulation model; for example, the first type of simulation model has three input ports, i.e., input ports x, y and z, the second type of simulation model has five output ports, i.e., output ports a, b, c, d and e, in a past historical connection record, x is connected with a, y is connected with b and z is connected with c, in another past historical connection record, x is connected with a, y is connected with c and z is connected with e, and in another past historical connection record, x is connected with a and the others are not connected;

if the number of the historical connection records is multiple, the occurrence frequency of each historical connection record can be counted; forming a recommended connecting line in the interface based on the times; furthermore, the final connection line may be determined in response to the user's operation on the recommended connection line, that is, the connection operation referred to above may be the user's operation on the recommended connection line.

In one example, a connection mode of a historical connection record with the highest frequency can be used as the recommended connection; furthermore, a connecting line can be formed between the frames of the two simulation models in the interface by a virtual line or/and a colored line, the connecting line is a recommended connecting line, and a user can click any part of the recommended connecting line to indicate that the recommended connecting line is agreed to be adopted as a final connecting line;

in another example, a connection mode of a plurality of historical connection records (for example, three) with the highest times can be adopted as three recommended connections; furthermore, according to the order of the times, a virtual line or/and a colored line can be formed between the frames of the two simulation models in the interface in sequence, and then the user can indicate that the recommended line is used as the final line through operations such as selection of an option frame.

If the number of the historical connection records is one, the connection mode can be directly selected as the recommended connection.

Through the mode, the connecting experience of the past connecting relation can be used for reference, the connecting efficiency is improved, and meanwhile, mistakes and omissions of engineers with shallow experiences during connection are avoided or reduced.

In a further example, each historical connection record may further be configured with a mapped scenario identifier for identifying characteristics of a test scenario, such as a scenario for testing a chassis domain controller, a scenario for testing a smart driving domain controller, and the like, where the characteristics of the scenario are not limited to the domain-based differentiation, and may further include, for example, a manufacturer, a use, and the like of the tested controller.
