In the field of automobile research and development and production, a plurality of controllers are mounted on commercial vehicles, passenger vehicles or non-road special vehicles; the controllers are connected into a complete network structure.

In order to facilitate understanding of the interactive grammar control simulator provided in the embodiments of the present application, an application scenario thereof is first described. The simulator capable of interactively controlling grammar is applied to the field of automobiles and is used for assisting a user in developing software. The amount of external data, the complexity of the architecture, depends on the protocol details agreed between the controllers. These protocols are not usually at the same time and can be fully described in the early stages of the development of the project. With the penetration of the project, the protocol is continuously modified and optimized, and for a protocol user (a data receiver), the protocol adaptation is required to be continuously carried out; and the project cannot use the whole protocol to develop the internal data processing in the early stage. Therefore, the embodiment of the application provides an interactive grammar control simulator, which is used for enabling a user of a protocol to 'look like accessing a complete communication protocol' in the initial stage of project development or in the stage of low maturity of the communication protocol, so that the communication state of the whole vehicle is simulated, and further, the simulator has the condition of developing a controller software prototype in the initial stage of the project. For ease of understanding, the following detailed description is provided in connection with the accompanying drawings.

In order to facilitate understanding of the simulator provided in the embodiments of the present application, first, a scenario in which the simulator is applied will be described. Referring to fig. 1, a simulator provided in an embodiment of the present application includes a kernel for performing signal processing and simulation. The simulator may also include a GUI module for receiving user input and interaction when information interaction is performed. Of course, other modules may be employed in addition to the GUI module. When in signal connection with the outside, connection can be made through an Adapter (Adapter) to communicate with the external signal receiver. Thus completing the input and output of the signal.

When the interaction is specifically performed, firstly, the GUI module receives user input and interaction, converts the user input and interaction into an interactive command form and transmits the interactive command form to a grammar interface (CMD-IF) in a Core. A synchronizer (synchronizer) in the Core communicates with the external signal receiver by calling an Adapter.

Referring to fig. 2, when internal information transmission is employed, all the constituent parts are in the same program. ModuleA is a data simulation module, and ModuleB and ModuleC are data real recipients. The ModuleA transmits the control command conforming to the grammar to the kernel one by one or once through a grammar interface (CMD-IF). The kernel checks the control command to simulate and sends the simulation result to the internal communication agent COMM. The COMM forwards the data to ModuleB and ModuleC, and the whole process of program simulation is completed.

In the case of signal simulation, the simulation is mainly performed by Core. Referring to fig. 3, fig. 3 is a block diagram illustrating a structure of an interactive grammar controllable simulator according to an embodiment of the present application, where the interactive grammar controllable simulator includes a grammar interface (COM-IF), a grammar Parser (Parser), a Generator (Generator), an execution module (workbench), and a synchronizer (synchronizer).

The grammar interface is used for reading the script and carrying out grammar checking, path detection and recursion detection on the read script; the grammar parser is used for parsing the grammar qualified by the grammar interface detection; the generator is used for carrying out signal generation instructions item by item on the analysis result generated by the grammar analyzer; the execution module is used for executing the instruction generated by the generator; after the execution module executes the instruction generated by the generator, the intermediate representation of the signal source is obtained, and the intermediate representation of the signal source is formed by { T, S, V }; wherein T is a tick, S is a signal ID, and V is a corresponding signal value; and the synchronizer is used for translating the intermediate representation and converting the intermediate representation of the signal source into a real signal. The construction and application of the various parts will now be described in detail with reference to the specific drawings.

CMD-IF is a grammar interface responsible for grammar checking, prompting, recursion detection, path detection, script reading. For preliminary processing of the script. When information interaction is carried out, external information is transmitted to the grammar interface, and preliminary processing is carried out through the grammar interface. As an alternative, the simulator further comprises a GUI module for receiving user input and interactions and for converting the user input into interactive command form for delivery to the grammar interface. I.e., the GUI accepts user input and interactions, converts them into interactive command form, and passes them to the CMD-IF in the kernel. The design of CMD-IF determines that the interactive grammar can be flexibly changed so as to be suitable for different use scenes.

Wherein the syntax of CMD-IF reception satisfies the following definition: the grammar use environment has context features, i.e. the environment variables remain valid after the end of a single statement. The grammar does not support recursive use cases to avoid loop referencing. And the commands may be separated by a semicolon.

By way of example, the syntax referred to in the embodiments of the present application may include the following examples: assignment: the following is carried out { name-string, value-string }, where name-string is the signal name and value-string is the signal value. The assignment is used to set a certain analog signal value.

Cycle: @ { name-string, interval }; wherein name-string is the signal name and interval is the trigger period (0 represents only one transmission). The period is used for setting a certain analog signal generation period.

And (3) transmitting: { name-string }. name-string is the signal name. The transmission is used to start transmitting a certain analog signal.

Pause: 11 { name-string, period }; wherein name-string is the signal name and period is the pause duration. The pause is used to pause the transmission of an analog signal and resume after a certain time.

Stopping: 1 $ { name-string }; stop to stop sending some analog signal.

A file: # { file-path }; wherein the file-path is a file path. The file is used to open a script file and execute commands in the script.

Flow: cmd1; cmd2; cmd3; … …. For executing the command stream in the write order at the same time.

When inputting the grammar to the COM-IF interface, the user or other device will input according to the above-set grammar format.

Parser is a grammar Parser responsible for parsing the legal grammar filtered by CMD-IF in stripes. In the case of specific parsing, different parsing such as semantic parsing and grammar parsing may be included. Based on the definition of grammar above, the definition of grammar is based on the design concept of command input. Therefore, conventional processes performed in conventional syntax analysis, semantic tree generation, and the like, as performed by procedural object-oriented compilers, are not applicable in the present design. In view of the requirement of the script file expanding function, the grammar checking is performed by using a mode matching mode based on the grammar design form of the design in the embodiment of the application.

When semantic analysis is carried out, the grammar analyzer is particularly used for removing redundancy of grammar checked by the grammar interface; splitting the instruction statement according to the token, and determining the instruction category according to the type indicator; element splitting of a single instruction statement is carried out according to the instruction category, and splitting parameters are recorded; and performing type checking, value checking, number checking and semantic filtering on all split data, and finally obtaining a naive instruction sequence after grammar and semantic processing are completed. The specific functions described above can be divided into the following steps:

step0: initializing analysis data;

redundant text removal, preliminary grammar checking (initializing data to single text strings).

Step1: splitting a compound CMD instruction;

splitting instruction sentences according to the token, and determining instruction categories according to the type indicators;

step2: splitting instruction parameters;

splitting elements of a single instruction statement according to the instruction category, and recording and splitting parameters;

step3: loading a script file;

if the single instruction is a script loading instruction, the script content is additionally loaded and inserted into the original instruction sequence, and the process is the same as the steps 0, step1 and Step 2. Before insertion, the operations such as parameter splitting and inspection are performed in the same manner.

Step4: rechecking parameters;

and carrying out post-processing on all split data, and carrying out type checking, value checking, number checking and semantic filtering. And finally obtaining a naive instruction sequence after grammar and semantic processing are completed, and performing intermediate simple conversion on the work task to be distributed.

The Generator is used as a Generator and is used for carrying out signal generation instructions on analysis results generated by the grammar analyzer item by item; that is, the Generator generates "signal generation instructions" item by item from the semantic analysis result obtained from the Parser.

The number of the workbench as an execution module can be 1 or more, and the workbench is responsible for executing signal generation instructions provided by the Generator. The specific implementation mode is as follows: after the execution module executes the instruction generated by the generator, the middle of the obtained signal source represents IR, and the middle of the signal source represents IR which is formed by { T, S, V }; where T is the tick (minimum time precision of tick, e.g. 5 ms.), S is the signal ID, and V is the corresponding signal value. In the embodiment of the application, IR is a signal representation that converts a signal generation instruction formed after parsing into a unified format. And is composed of triples { T, S, V }; so that different inputs can be converted into a unified signal for input to the synchronizer for simulation.

Synchroniuser acts as a synchronizer to provide a simulated environment. When in use, the intermediate representation can be translated according to the set simulation environment, the intermediate representation is converted into a real signal (changed into a real signal form in the actual engineering), and the synchronization problem when multiple signals occur can be solved.

As can be seen from the above description, in the embodiment of the present application, by adopting standardized definition of grammar, a user of a protocol can "look like accessing a complete communication protocol" in an early stage of development of a project or in a stage of low maturity of the communication protocol, so as to simulate a communication state of a whole vehicle, and further provide conditions for initial development of a controller software prototype of the project.

In addition, the simulator also comprises a global context storage module LUT used for organizing the lookup table data structure. When each module operates, the global context storage module is used for storing the operation data of each module so as to judge whether the operation logic of each module is normal or not according to the stored data.

In order to facilitate understanding of the simulator provided by the embodiment of the application, the embodiment of the application also provides a simulation method.

Referring to fig. 4, the present application further provides an interactive grammar control simulation method, which includes the following steps:

step 001: reading the script through a grammar interface and carrying out grammar checking, path detection and recursion detection on the read script;

specifically, user input and interaction are received first, and the user input is converted into an interactive command form and transmitted to a grammar interface for script reading. Such as through a GUI module or other interaction module.

In addition, the received grammar satisfies the following definition:

the grammar use environment has context features, i.e. the environment variables remain valid after the end of a single statement. The grammar does not support recursive use cases to avoid loop referencing. And the commands may be separated by a semicolon.

By way of example, the syntax referred to in the embodiments of the present application may include the following examples: assignment: the following is carried out { name-string, value-string }, where name-string is the signal name and value-string is the signal value. The assignment is used to set a certain analog signal value.

Cycle: @ { name-string, interval }; wherein name-string is the signal name and interval is the trigger period (0 represents only one transmission). The period is used for setting a certain analog signal generation period.

And (3) transmitting: { name-string }. name-string is the signal name. The transmission is used to start transmitting a certain analog signal.

Pause: 11 { name-string, period }; wherein name-string is the signal name and period is the pause duration. The pause is used to pause the transmission of an analog signal and resume after a certain time.

Stopping: 1 $ { name-string }; stop to stop sending some analog signal.

A file: # { file-path }; wherein the file-path is a file path. The file is used to open a script file and execute commands in the script.

Flow: cmd1; cmd2; cmd3; … …. For executing the command stream in the write order at the same time.

Step 002: analyzing the grammar qualified by the grammar interface through a grammar analyzer;

specifically, based on the definition of grammar above, the definition of grammar is based on the design concept of command input. Therefore, conventional processes performed in conventional syntax analysis, semantic tree generation, and the like, as performed by procedural object-oriented compilers, are not applicable in the present design. In view of the requirement of the script file expanding function, the grammar checking is performed by using a mode matching mode based on the grammar design form of the design in the embodiment of the application.

When semantic analysis is carried out, the grammar analyzer is particularly used for removing redundancy of grammar checked by the grammar interface; splitting the instruction statement according to the token, and determining the instruction category according to the type indicator; element splitting of a single instruction statement is carried out according to the instruction category, and splitting parameters are recorded; and performing type checking, value checking, number checking and semantic filtering on all split data, and finally obtaining a naive instruction sequence after grammar and semantic processing are completed. The specific functions described above can be divided into the following steps:

step0: initializing analysis data;

redundant text removal, preliminary grammar checking (initializing data to single text strings).

Step1: splitting a compound CMD instruction;

splitting instruction sentences according to the token, and determining instruction categories according to the type indicators;

step2: splitting instruction parameters;

splitting elements of a single instruction statement according to the instruction category, and recording and splitting parameters;

step3: loading a script file;

if the single instruction is a script loading instruction, the script content is additionally loaded and inserted into the original instruction sequence, and the process is the same as the steps 0, step1 and Step 2. Before insertion, the operations such as parameter splitting and inspection are performed in the same manner.

Step4: rechecking parameters;

and carrying out post-processing on all split data, and carrying out type checking, value checking, number checking and semantic filtering. And finally obtaining a naive instruction sequence after grammar and semantic processing are completed, and performing intermediate simple conversion on the work task to be distributed.

Step 003: carrying out signal generation instructions item by item on the analysis result generated by the grammar analyzer through a generator;

step 004: executing the instruction generated by the generator through an execution module; after the instruction generated by the generator is executed, the intermediate representation of the signal source is obtained, and the intermediate representation of the signal source is formed by { T, S, V }; wherein T is a tick, S is a signal ID, and V is a corresponding signal value;

specifically, after the execution module executes the instruction generated by the generator, the intermediate representation IR of the obtained signal source is formed by { T, S, V }; where T is the tick (minimum time precision of tick, e.g. 5 ms.), S is the signal ID, and V is the corresponding signal value. In the embodiment of the application, IR is a signal representation that converts a signal generation instruction formed after parsing into a unified format. And is composed of triples { T, S, V }; so that different inputs can be converted into a unified signal for input to the synchronizer for simulation.

Step 005: and translating the intermediate representation according to the set simulation environment through a synchronizer, and converting the intermediate representation into a real signal.

Specifically, the Synchronizer acts as a synchronizer to provide a simulation environment. When in use, the intermediate representation can be translated according to the set simulation environment, the intermediate representation is converted into a real signal (changed into a real signal form in the actual engineering), and the synchronization problem when multiple signals occur can be solved.

After conversion to a true signal, the true signal may be sent to an external signal recipient through a converter. To output the simulation result.

In the above technical solution, by adopting standardized definition of grammar, the user of the protocol can "look like accessing the complete communication protocol" in the early stage of the project development or in the stage of the low maturity of the communication protocol, thereby simulating the communication state of the whole vehicle and further having the condition of developing the software prototype of the controller in the early stage of the project.

As can be seen from the above description, the embodiment of the present application develops a software with interactive grammar parsing capability, and further performs standardized definition on grammar, so that a user of the protocol can "look like accessing a complete communication protocol" at an early stage of development of the project or at a stage of low maturity of the communication protocol, thereby simulating a communication state of the whole vehicle, and further having a condition of initially developing a software prototype of the controller of the project. The embodiment of the application can solve the paradox that each controller faces the 'that when the controller is not connected with other controllers to send data, the controller cannot process the data and generate new data to send to the other controllers' through the interactive grammar scheme. Based on this scheme, it can be extended to include: independent automation programs, independent GUI programs, embedded automation modules, embedded interaction modules, and the like. The application scenes are more, and the platform is crossed.
