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 in order to avoid unnecessarily obscuring descriptions of the embodiments of the present application. 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.

The embodiment of the application provides a model processing method, a device, a terminal device and a storage medium, and the detailed description will be given 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:

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

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

In some embodiments of the present application, a target simulation model that needs to be connected to a port 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 determining a target simulation model which needs port connection, determining a simulation model which needs to be contained in a scene and a model type of the simulation model according to scene creation requirements, determining a JSON file of an unconfigured parameter corresponding to the simulation model according to the model type, and performing parameter configuration on the JSON file according to scene requirements and function requirements of the simulation model to obtain the JSON file with parameter configuration completed. After performing mutation, compiling and other processing on the JSON file with the parameter configuration completed, a model instance of the corresponding simulation model can be generated, and the simulation model in the final model file corresponding to the model instance can comprise 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, an expressive model, a sensor model, a BSU model, a BMS model, and the like.

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

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 is performed, a target simulation model for performing port connection is determined according to needs. After the target simulation model is determined, a final model file corresponding to the target simulation model is obtained from a database or a disk of the HIL system through a preset association relation, or a final model file corresponding to the target simulation model is obtained from a database or a disk connected with the HIL system. Information corresponding to the target simulation model can be recorded in the final model file, and the information comprises model characteristics, data ports, port description information and the like. In addition, the information such as the port description information may 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: based on the file reading result, the display interface of the connection tool displays the data port and the frame corresponding to the data port.

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

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

Because the relevant information of the data ports of the target simulation model is predefined and recorded in the model description file, after the model description file is compiled to obtain the corresponding final model file, the corresponding frame can be generated by reading the file of the final model file through the connection tool, the frame can display the contained data ports and the port names of each data port and/or the display names of the data ports on the display interface of the connection tool, and the display names are recorded in the result of file reading.

As shown in fig. 2, the box in the embodiment of the present application is used to describe the setting manners of the data ports included in the model description file and the final model file, where the setting manners include the port direction, the position of the ports relative to the box, the number of ports of the data ports, and the port functions. These are also understood to be the result of file reading.

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 used for connecting the data ports on the frame 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 as to realize port connection through operation on the display interface.

If the target simulation model for port connection is one, the final model file corresponding to the target simulation model is imported into the connection tool, and a frame corresponding to the imported final model file is displayed 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 a plurality of target simulation models are connected through the port, the final model files corresponding to the target simulation models are led into the connecting tool, and then the frame corresponding to each final model file is displayed on the display interface of the connecting tool. And the port connection is realized by the connection operation of the frame tools or the data ports between the frame tools 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.

The data ports include input ports, output ports, and other functional types of data ports. In the embodiment of the application, the main basis is the port connection between the output port and the input port, and the target data port at least comprises a target output port and at least one target input port, so that the port connection between the target data ports is the connection from the target output port to the target input port.

Optionally, the data port can be obtained through the structure of the frame, and the corresponding port description information can be displayed by clicking the data port on the frame.

For example, the 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 opposite to the input port displays the port description information of the input port by means of a small window.

For example, the 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 switches to a corresponding interface displaying port description information, on which port description information of the input port is displayed.

After the frame is displayed on the display interface of the connection tool, the contained data port can be known through the structure of the frame. However, when the port connection is performed, not all the data ports on the frame are required to be connected, but the data port required to be connected is determined as the target data port from the data ports according to the scene creation requirement and the port function of the data port, and the target data port is required to be connected.

If it is determined that only a part of the data ports of the frame are required to be connected according to the scene creation requirement and the port function of the data ports, the data ports determined on the frame are used as target data ports to be connected. If it is determined that all the data ports of the frame are connected by ports according to the scene creation requirement and the port function of each data port, all the data ports on the frame are used as target data ports for port connection.

Optionally, in an embodiment of the present application, the port description information includes a port name, a byte order, a number of items, a display name on a display interface, a port type, a queue attribute, a structure attribute, a port direction, and 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]
		Endian (byte order)	LSBfirst
Item quantity	1
		Displaying names	AOUT[0]
Port type	Double
		Whether or not to queue	False
Whether or not to structure	False
		Port direction	Input
Path	InputPort/AOUT[0]

TABLE 1

The byte sequence describes whether the sequence in storage and the sequence in input (output) are the first or the last, the number of items describes the set number of the target data ports in the corresponding boxes, whether the target data ports have queue attributes, whether the target data ports have structure attributes, and the port types describe the types of the target data ports. It should be noted that, in other embodiments, the port description information may be set separately.

Alternatively, 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 name 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 that signal transmission is performed based on the connection relation when the target simulation model works.

After determining the connection relation between the target data ports of the target simulation model, port connection is performed on the target data ports with the connection relation, namely port connection is performed on the target data ports of the target simulation model, or port connection is performed on the target data ports of the target simulation model and the target data ports of other target simulation models.

For example, determining that the target simulation model to be connected with the port is one, determining that the target simulation model includes two target data ports, and connecting the target output port with the target input port to realize data transmission if the two target data ports are the target output port and the target input port respectively.

For example, the target simulation model for determining the port connection includes a first target simulation model and a second target simulation model, determining that the target data port of the first target simulation model is a first target data port, determining that the target data port of the second target simulation model is a second target data port, and determining that the first target data port is a target output port and the second target data port is a target input port. And connecting the target output port with the target input port to realize data transmission and connection between the simulation models.

In the embodiment of the application, the port connection rule is preset, and the port connection is realized by combining the port connection rule when the port connection is performed.

Port connection rules, which can be understood as defining the relationship between the results of 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 connection is allowed and/or recommended between ports can be used as an implementation of the port connection rule;

port description information, which can be understood as any information describing the 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 is understood to be a queue identification);

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

the structural attribute is used for representing: the data that can be transmitted by the corresponding destination data port includes multiple sets of data 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 port connection rules:

TABLE 2

As shown in table 2, defined in table 2 are collocation rules for different port types. Wherein "∈" indicates connectable, which can be understood as allowing connection "+| -! "indicates connectable but generates an alarm, which may be understood as not recommending a connection, and" x "indicates unconnectable, which may be understood as not allowing a 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 with the connection relationship may be a connection between a data port of a frame corresponding to one target simulation model and a data port of the frame itself, or may be 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 frames to illustrate the connection of the two frames.

For example, the target simulation model to be connected to the port includes a first target simulation model and a second target simulation model, 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 the display interface of the connection tool, the first target data port and the second target data port are connected in a mode of connecting line operation 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, operation results such as correct connection, incapability of connection or warning line connection can appear after the connection operation is performed. If the operation result is that the warning line is connected, corresponding prompt information is displayed on a display interface of the connecting tool, and the content of the prompt information can be 'warning line is connected, please check'.

For example, when the connection is correct, the connection line is displayed on the display interface, but the prompt information is not displayed; when the warning line is connected, the connecting line is displayed on the display interface, but the warning information is displayed; if the connection is impossible, the display interface automatically cleans the invalid connection and displays corresponding prompt information.

Under the condition that the warning line is connected or can not be connected, corresponding prompt information is displayed, automatic analysis can be performed according to corresponding port description information and port connection rules, and analysis results are displayed on a display interface for reference of line connecting personnel.

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

The process can be understood as an implementation manner of determining that the connection relationship and the port description information meet the port connection rule, that is, "the data types are the same, and the data transmission direction corresponds to the filling condition or the necessary condition that the connection relationship and the port description information meet the port connection rule".

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

Wherein, the data transmission direction corresponds to be understood as: one of the two connected target data ports is an input port, and the other is an output port.

As shown in fig. 3, fig. 3 shows a structure of two frames, wherein the frame on the left side is set as a first frame, the frame on the right side is set as a second frame, a first target data port on the first frame is AIN 2, and a 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 is right in the figure, the port direction of the second target data port is left, 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 port direction, the port connection is performed in combination with a port connection rule. For example, the first target data port AIN [2] is the output port of Int8 and the second target data port AOUT [2] is the input port of Int16 shown in fig. 3, then the first target data port and the second target data port may be wired, and after the wired operation is performed, as shown in fig. 3, then the two target data ports in fig. 3 are connections directed from the output port to the input port.

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

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

Meanwhile, according to the port connection rule, the target data port which has a 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; further, in general, the input ports may be selectively configured to have queue attributes.

In some examples, the output port may not be configured, e.g., a target data port as an output port may be connected to both one target data port and a plurality of target data ports. In some examples, the output port may also be selectively configured to have a queue attribute,

the queue attribute may also be understood as a queue identifier for identifying whether a corresponding port allows connection to a plurality of 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 data ports connected based on the queues;

in some embodiments, the queue attribute may be further understood as a port connection manner describing a data port, and after determining the target data port, whether the target data port has the queue attribute may be known through port description information of the target data port. If yes, port connection is carried out according to the queue attribute and the port connection rule. If not, the target data port is determined to be connected through a one-to-one port connection mode.

For example, the object simulation model requiring port connection includes a first object simulation model including a first object data port, a second object simulation model including a second object data port, and a third object simulation model including a third object data port. The first target data port, the second target data port and the third target data port are connected, 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 a queue attribute, the port connection mode corresponding to the queue attribute is one-to-many connection. When the ports are connected according to the connection relation, the first target data port is connected with the second target data port and the third target data port respectively.

For example, the target simulation model requiring port connection 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 are connected, 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 the ports are connected according to the connection relation, the first target data port and the second target data port are connected.

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

The process can be understood as an implementation manner of determining that the connection relationship and the port description information meet the port connection rule, that is, the connection relationship and the port description information meet the requirement or the requirement of the port connection rule, that the structure attribute of the target data port with the structure attribute connected in the connection relationship is the same.

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

wherein the attribute information of the structural attribute is used for characterizing: the data which can be transmitted by the corresponding target data port comprises a plurality of groups of data which are transmitted in a designated sequence, each group of data has a corresponding data type, and furthermore, the data port with the structure attribute is usually complex and needs to transmit a plurality of groups of data with different data types. In other words, for two data ports with identical attribute information of the structural attribute, the manner in which the corresponding simulation model processes and writes data when outputting data corresponds to the manner in which the corresponding simulation model extracts and parses data when receiving 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 writing and the analysis after extracting the group of data in the processing mode of the same data type.

The structure attribute may also be understood as describing whether the corresponding target data port has an affiliated structure. With respect to the definition of a structure, it is understood that the structure includes a plurality of members (i.e., each group of data transmitted in a given order may be considered a member), each member having a corresponding data type. For example, a structure includes a set of data of Int8 data type, a set of data of Uint8 data type, and a set of data of Uint16 data type, and then three sets of data need to be transmitted, and the structure includes three members.

When the connection relation between the target data ports with the structure attribute is determined, the target data ports with the connection relation have the same structure attribute, and the port connection can be performed. The definition of the same structure attribute is that the name of the structure, the number of the structure ports, the type of the structure ports and the sequence of the structure ports of the target data port to be connected are the same.

Multiple types of structures may be defined in advance, and corresponding names are set for each type, and when determining whether the structure attributes of the target data ports to be connected are the same structure attributes, determination can be made by judging the belonging structure names.

In one embodiment, after determining two target simulation models to be connected, if it is assumed that the two target simulation models are the fourth target simulation model and the 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 the fourth target simulation model (namely a first simulation model) and a simulation model of the fifth target simulation model (namely a second simulation model); the historical connection record represents a connection relation which has occurred in the past of a data port between the first type simulation model and the second type simulation model; for example, the first simulation model has three input ports, namely, input ports x, y and z, respectively, the second simulation model has five output ports, namely, output port a, b, c, d, e, wherein x is connected with a, y is connected with b, z is connected with c in one past history connection record, x is connected with a, y is connected with c, z is connected with e in another past history connection record, and x is connected with a and the other history connection records are not connected with each other;

if the number of the history connection records is multiple, counting the occurrence times of each history connection record; forming a recommended connecting line in the interface based on the times; further, the final link may be determined in response to a user's operation on the recommended link, i.e., the link operation referred to above may be a user's operation on the recommended link.

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

in another example, a connection mode of a plurality of history connection records (for example, three) with the highest times can be adopted as three recommended connection lines; further, the broken lines or/and colored lines may form a line between the frames of the two simulation models in the interface in order from more to less, and then the user may indicate which recommended line is desired to be used as the final line by selecting the option box or the like.

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

Through the mode, the connection experience of the past connection relation can be used for reference, the connection efficiency is improved, and meanwhile, the error and the leakage of engineers with shallow experience in connection are avoided or reduced.

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

Furthermore, in the process of acquiring one or more historical connection records of a simulation model of the fourth target simulation model (i.e., the first simulation model) and a simulation model of the fifth target simulation model (i.e., the second simulation model), only the historical connection record with the scene identifier completely identical to or partially identical to the scene under test can be acquired.

Furthermore, the connection record with stronger correlation can be applied to the test, and the recommended connection line is guaranteed to be helpful to a certain extent.

The model processing method of the embodiment of the application comprises the following steps: determining a target simulation model needing port connection and a data port available for connection in the target simulation model in a plurality of simulation models of the HIL system; determining target data ports in the data ports, and acquiring port description information of each target data port; and determining the connection relation between the target data ports according to the port description information and a preset port connection rule, so that signal transmission is performed based on the connection relation when the target simulation model works.
