Fig. 1 is an exemplary flowchart of an interface expansion method of a virtual simulation system according to an embodiment of the present invention. As shown in fig. 1, the method may include the steps of:
In this embodiment, in a specific implementation, the user interface of the target open communication protocol may include: connection attributes, actions to create input-output variables, and input-output signal attributes of the target open communication protocol. Accordingly, the resource class file may include: a first resource class file for defining the connection attribute; a second resource class file for defining the create input output variable action; and a third resource class file for defining said input output signal attributes.
In one embodiment, the connection attributes of the target open communication protocol include: some or all of remote IP address, remote communication port, local communication port, input data type, input data length, output data type, output data length, data exchange, debug, author, version.
The act of creating an input-output variable may comprise: some or all of create variables, add variables, import variables, export variables, and delete variables.
The signal attributes may include: input-output address and signal data type.
For example, in one example, for a SIMIT software system, the resource class file may include:
1) The node property resource (node properties. Resx) is a first resource class file, and is used to define connection properties of a target open communication protocol, such as a remote IP address, a communication port, and the like.
In one example, in order to arrange the attributes in a certain order in the connection attributes, the name names of the attributes may be arranged in a set order, for example, in a manner of "Configuration _ PA _", "Configuration _ PB _", or "Configuration _ PC _". For example, in an example, taking UDP connection as an example, the name of its connection attribute and its corresponding value may include:
"Configuration _ Caption", and its corresponding value may be "UDP Communication";
"Configuration _ PA _ RemoteIP", which may correspond to a value of "Remote IP Address";

"Configuration _ PI _ Debug", which may correspond to a value of "Debug";
"Configuration _ PJ _ Author", which may correspond to a value of "Author";
"Configuration _ PK _ Version", and its corresponding value may be "Version".
2) Resx, a second resource class file, is used to define actions for input and output variables, such as creating an input or output variable, adding a byte input variable, deleting a Word type output variable, importing a variable, exporting a variable, deleting the last variable, etc. For example, in an example, taking UDP connection as an example, the names of the input and output variables and their corresponding values may include:
"Configuration _ AddDefault", which may correspond to a value of "Generation I/O (create input or output variable)"; this variable will correspond to a "Generate Input or Output variable" button generated on the user interface, and when this button is clicked, the corresponding SIMIT Input or Output variable will be created based on the attributes "Input data length", "Output data length", etc. defined in the UDP connection attribute interface in this embodiment.
"Configuration _ addlnput 1", which may correspond to a value of "+ Input Byte (add Byte Input variable)"; this variable will correspond to an "add Byte input variable" button generated on the user interface, which when clicked, will add a simple input variable of Byte type in this embodiment.
"Configuration _ addlnput 2", which may correspond to a value of "+ Input Word (add font Input variable)"; this variable will correspond to an "add font input variable" button generated on the user interface, which when clicked, will add a SIMIT input variable of the Word type in this embodiment.
"Configuration _ addlnput 3", which may correspond to a value of "+ Input DWord (add bigram Input variable)"; this variable will correspond to an "add double type input variable" button generated on the user interface, which when clicked, will add a SIMIT input variable of DWord (double type) type in this embodiment.
"Configuration _ AddOutput1", which may have a corresponding value of "+ Output Byte (add Byte Output variable)"; this variable will correspond to an "add Byte output variable" button generated on the user interface, which when clicked, will add a simple output variable of Byte type in this embodiment.
"Configuration _ AddOutput2", whose corresponding value may be "+ Output Word (add font Output variable)"; this variable will correspond to an "add font output variable" button generated on the user interface, which when clicked, will add a SIMIT output variable of Word (font) type in this embodiment.
"Configuration _ AddOutput3", whose corresponding value may be "+ Output DWord (add double-type Output variable)"; this variable will correspond to an "add double type output variable" button generated on the user interface, which when clicked, will add a DWord (double type) type SIMIT output variable in this embodiment.
"Configuration _ ExportSignals", which may correspond to a value of "ExportSignals (derived variables)"; this variable will correspond to an "export variables" button generated on the user interface, which when clicked exports the already defined SIMIT input output variables into the CSV file in this embodiment.
"Configuration _ importation Signals", the corresponding value of which may be "importation Signals"; this variable will correspond to an "import variable" button generated on the user interface, and when this button is clicked, the corresponding SIMIT input or output variable will be generated from the imported CSV file in this embodiment.
"Configuration _ importsignalfromppartner", which may correspond to a value of "importsignals From Partner" (negation generating variable) "; the variable corresponds to a button of 'negating generation variable' generated on the user interface, when the button is clicked, the local side SIMIT input and output variable is generated according to the type of the communication partner side SIMIT input and output variable in the embodiment, for example, the partner side SIMIT input and output variable is used as the input variable, and a corresponding output variable is created on the local side.
"Configuration _ removeLastSignal", which may correspond to a value of "Remove Last Signal (delete Last variable)". The variable will correspond to a "delete last variable" button generated on the user interface, which when clicked, will delete the last variable in this embodiment.
3) Signal properties resource (signal properties. Resx), a third resource class file, is used to define the signal properties of SIMIT, such as address, type, etc.
In one example, for the SIMIT software system, a configuration class file (e.g., configuration. Cs) may be used to configure various attributes defined in the UI interface, including initializing connection parameters of a target open communication protocol, such as UDP, and defining types and lengths of SIMIT input and output variables for data exchange between the target open communication protocol, such as UDP, and the external device.
For example, for the connection parameter "PG _ OutputDataLength" defined above, when initializing it, the specific process may include: the "output data length" of the integer data is set to a default value, e.g., 100. Returning a default value of the set output data length, such as 100, according to the current output data length, and checking the effective length of the output variable according to different data types of the variable; for example, when the variable type is Byte (Byte) type, the output variable length is 1460 at maximum, and when the variable type is Word (Word) type, the output variable length is 780 at maximum.
For another example, for "Configuration _ AddDefault" defined in the action resource (actions. Resx), the action event corresponding to the create simple input/output variable is "AddDefault", and the button name assigned to the action event in the UI interface is "generation I/O (create input/output variable)". The specific execution process of the action is as follows: all created SIMIT input and output variables are deleted. Then, a new SIMIT input variable is created according to different types of the input variable, and when the type of the input variable is Byte (Byte), input DataLength (input data length) SIMIT Byte type input variables are continuously created; when the input variable type is a Word type, continuously creating inputDataLength (input data length) SIMIT font input variables; when the input variable type is a doubleword (DWord) type, input datalength (input data length) SIMIT doubleword type input variables are successively created. Meanwhile, a new SIMIT output variable is created according to different types of the output variable, and when the type of the output variable is Byte (Byte), output DataLength (output data length) SIMIT Byte type output variables are continuously created; when the output variable type is a Word type, continuously creating output datalength (output data length) SIMIT font output variables; when the output variable type is a double word (DWord) type, output datalength (output data length) SIMIT double-word output variables are successively created.
In one example, for a SIMIT software system, a communication class file (e.g., communication. Cs) may enable transmission of targeted open communication protocol, such as UDP communication data, by invoking a number of system events provided by the SIMIT API interface.
For example, the Open event provided by the SIMIT API interface is called to traverse the input and output variables, generate byte addresses and bit addresses for the input and output variables, and call a target Open communication protocol Client function, such as a UDP Client function, to create communication of the target Open communication protocol when the virtual simulation system runs. During specific implementation, rich diagnostic information can be further added, so that a user can conveniently find a problem when the UDP communication fails.
The communication class file converts the received target open communication protocol such as UDP data into output data of SIMIT by calling a first cycle interrupt event such as 'Call 1' provided by the SIMIT API interface.
In one example, the specific implementation process may include: judging the length of UDP communication received data, and if the length is greater than 0, converting the UDP received data into a Bool (Bool) type array; traversing all SIMIT output variables of which the data types are integer (Int), acquiring the start bit address of each SIMIT output variable, and performing assignment operation on the SIMIT output variables according to the types of the SIMIT output variables; for example, when the type of the SIMIT output variable is Byte (Byte), reading a Byte of data from a start bit (start bit of the SIMIT output variable) in a Boolean array after receiving data conversion from UDP, and assigning the Byte of data as the SIMIT output variable; traversing all SIMIT output variables of which the data types are Bool (Bool) types, acquiring the addresses of the start bits of the SIMIT output variables, reading one bit of data from the start bit (the start bit of the SIMIT output variable) in a Bool array after receiving data conversion from UDP, and assigning the bit of data as the SIMIT output variables.
The communication class file traverses the input data of the SIMIT by calling a second circular interrupt event such as a 'call 2' event provided by the SIMIT API interface, converts the input data of the SIMIT into a target open communication protocol such as UDP data and transmits the data.
In one example, the specific implementation process may include: traversing all SIMIT input variables of which the data types are integer (Int), acquiring initial Bit addresses of the SIMIT input variables, converting the values of the SIMIT input variables into Byte (Byte) arrays with different lengths according to different data types of the input variables, converting the Byte (Byte) arrays converted from the SIMIT input variables into Bit (Bit) arrays, and uniformly storing the values of the Bit (Bit) arrays after the conversion of each SIMIT input variable in a Bit sending (sendBits) array; traversing all SIMIT input variables with the data type of Bool (Bool), uniformly storing the value of each SIMIT input variable in a Bit sending (sendBits) array, converting the Bit sending (sendBits) array with the Bit (Bit) type into a Byte sending (sendBytes) array with the data type of Byte (Byte), executing a UDP sending task, and sending the SIMIT input variable data to a communication partner through UDP.
102, compiling the three types of files and generating an executable file, so that when the executable file is executed, the data of the target open communication protocol can be transmitted between the virtual simulation system and a target open communication protocol device, and the interface extension of the target open communication protocol of the virtual simulation system is realized.
For example, in one example, for the three types of files in the above example, a simple _ UDP _ client.exe executable file may be generated, and a "UDP" folder may be created under the simple installation path and then created under the folder, and the executable file generated by compiling may be copied into the "UDP" folder.
The interface expansion method based on the virtual simulation system can realize the interface expansion of the virtual simulation system, and after the interface expansion is finished, the data communication of the target open type communication protocol can be carried out based on the expanded interface. The method for using the extended interface of the virtual simulation system will be briefly described below.
FIG. 2 is a flowchart illustrating a method for using an extended interface of a virtual simulation system according to an embodiment of the present invention. As shown in fig. 2, the method may include the operations of:
In this embodiment, the target open communication protocol connection interface may include a configuration interface of a connection attribute set by the target open communication protocol connection and a configuration interface of an action, a type, and a length of an input/output variable. Accordingly, the receiving the configuration of the target open communication protocol connection by the user based on the target open communication protocol connection interface comprises: and receiving the connection attribute set for the target open communication protocol connection by the user through the configuration interface of the connection attribute and the configuration of the action, the type and the length of the input and output variable performed by the configuration interface based on the type and the length of the input and output variable.
A schematic diagram of a portion of the UDP connection interface in one example is shown in fig. 3. As shown in fig. 3, the left side has a logo of the UPD connection, and the right side upper side is provided with buttons corresponding to respective actions of the input/output variables, i.e., "create input/output variable", "add byte input variable", "add font input variable", "add double font input variable", "add byte output variable", and "add byte output variable". The upper middle part of the right side of the figure 3 is provided with an input variable interface and an output variable interface corresponding to the buttons. For example, when clicking the top "create input/output variables" button, the SIMIT input/output variables of the corresponding number and data type are created according to the definition of the second resource file in step 101, and a schematic diagram of the created input variables and output variables is shown in fig. 4. In addition, other buttons can be used for increasing and decreasing the SIMIT IO variable.
The lower part of the right side of fig. 3 is provided with a configuration interface for the connection attribute of the UDP connection and a configuration interface for the type and length of the input/output variables.
For example, in one example, a SIMIT simulation may be initiated, and the simulation platform will automatically invoke a SIMIT UDP client exe executable that will automatically create a UDP function, UDP communicate with the communication partner at recurring time intervals, and implement a recurring interaction of the SIMIT input and output signals with UDP data.
