[0052] The above drawings show clear embodiments of the present disclosure, which will be described in more detail below. These drawings and text descriptions are not intended to limit the scope of the present disclosure in any way, but to illustrate the concepts of the present disclosure to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0053] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0054] In the embodiments of the present application, "at least one" means one or more, and "more" means two or more. "And / or" describes the association relationship of the associated objects, indicating that there can be three relationships. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone, where A and B can be singular or plural. In the text description of the present application, the character " / " generally indicates that the associated objects before and after are in an "or" relationship.

[0055] The technical solution provided in the embodiment of the present application can be applied to the code generation scenario. The realization of software functions is inseparable from the code. For example, due to different manufacturers and models, electric vehicles have different control methods for contactors. They can be controlled by the battery management system (Battery Management System, referred to as BMS), or by other electronic control devices of the vehicle. For electric vehicles controlled by BMS software, due to the different technical solutions that need to be adopted by the whole vehicle, software developers often need to write different codes to realize different overall scheduling and control timing of the BMS software, so as to achieve the purpose of adapting to the different needs of the whole vehicle.

[0056] In the prior art, technicians determine the functions that the software to be developed needs to implement based on the received instructions, and manually write corresponding codes according to the functions that the software to be developed needs to implement, so that the software can implement various functions. However, manual code writing takes a lot of time, and in the process of code writing, writing errors may occur, which reduces the efficiency of code generation.

[0057] In order to solve the problem of low efficiency in code generation, automatic code generation can be considered. The embodiment of the present application provides a code generation method, which first receives a code generation instruction; wherein the code generation instruction includes an identifier of a pending business; abstracts the pending business indicated by the identifier of the pending business to obtain a description file corresponding to the pending business; wherein the description file includes multiple abstraction parameters and parameter values ​​corresponding to each abstraction parameter; and generates a target code corresponding to the pending business according to the multiple abstraction parameters and the parameter values ​​corresponding to each abstraction parameter; and outputs the target code corresponding to the pending business.

[0058] It can be seen that in the embodiment of the present application, when generating code, a code generation instruction is first received; wherein the code generation instruction includes the identifier of the business to be processed; the business to be processed indicated by the identifier of the business to be processed is abstracted to obtain a description file corresponding to the business to be processed; wherein the description file includes multiple abstraction parameters and parameter values ​​corresponding to each abstraction parameter; and according to the multiple abstraction parameters and the parameter values ​​corresponding to each abstraction parameter, a target code corresponding to the business to be processed is generated. It can be seen that when generating code, there is no need for technicians to manually write it, and automatic code generation is achieved, thereby effectively improving the efficiency of code generation.

[0059] The code generation method provided by the present application will be described in detail below through specific embodiments. It is understandable that the following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0060] Figure 1 The following is a flowchart of a code generation method provided by an embodiment of the present application. The code generation method can be executed by software and / or hardware devices. For example, the hardware device can be a code generation device, and the code generation device can be a terminal or a processing chip in the terminal. For example, see Figure 1 As shown, the code generation method may include:

[0061] S101, receiving a code generation instruction.

[0062] The code generation instruction includes an identifier of the business to be processed.

[0063] For example, the code generation instruction has multiple forms, which can be in text form or in characteristic symbols, and is mainly used to identify the pending business. The embodiment of the present application does not impose any restrictions on the form of the code generation instruction and the form of the pending business identification.

[0064] S102: Perform abstract processing on the pending business indicated by the identifier of the pending business to obtain a description file corresponding to the pending business.

[0065] For example, when abstracting the pending business indicated by its identifier, the pending business can be parsed first to obtain the status information, condition information and execution action information corresponding to the pending business; and based on the status information, condition information and execution action information, the pending business can be abstracted.

[0066] Among them, the state information may include multiple different states, the condition information may include multiple different conditions, the execution action information may include multiple different execution actions, and the state information corresponding to the pending business may include multiple sub-states. For example, the state information may include 3 sub-states, namely, the initialization sub-state, the running sub-state, and the exit sub-state. The condition information may be the jump information between the different states, and the execution action information may be the action to be performed for each sub-state. It is understandable that the state information, condition information, and execution action information can all be represented by special characters, and the embodiments of the present application do not impose any restrictions on the specific representation method.

[0067] In the embodiment of the present application, by parsing the business to be processed into status information, condition information and execution actions and performing abstract processing, it is possible to convert the business to be processed into a language that can be recognized by a computer, which can effectively improve the success rate of code generation.

[0068] When the pending business indicated by the identifier of the pending business is abstracted, a description file corresponding to the pending business can be obtained, and the description file includes multiple abstraction parameters and parameter values ​​corresponding to each abstraction parameter. Among them, the abstraction parameters can be the state information, condition information, execution action information obtained by parsing the pending business, and the corresponding specific information and quantity, and the parameters corresponding to the abstraction parameters can be the specific numerical values ​​corresponding to the state information, condition information, and execution action information, respectively. The embodiment of the present application does not impose any limitation on the specific content of the abstraction parameters and the parameter values ​​corresponding to each abstraction parameter. Among them, the description file can be in a variety of types. For example, the description file can be an EXCEL table. The embodiment of the present application does not impose any limitation on the specific type of the description file.

[0069] After abstracting the pending business indicated by the identifier of the pending business and obtaining the description file corresponding to the pending business, the target code corresponding to the pending business can be generated according to the multiple abstraction parameters and the parameter values ​​corresponding to the abstraction parameters, that is, the following S103 is executed:

[0070] S103: Generate a target code corresponding to the service to be processed according to a plurality of abstract parameters and parameter values ​​corresponding to each abstract parameter.

[0071] When generating the target code corresponding to the business to be processed based on multiple abstract parameters and the parameter values ​​corresponding to each parameter, the abstract parameters and the parameter values ​​corresponding to each abstract parameter can be directly obtained, or the abstract parameters and the parameter values ​​corresponding to each abstract parameter in the description can be read by obtaining the description file. Specifically, the embodiments of the present application do not impose any restrictions.

[0072] After obtaining a plurality of abstract parameters and parameter values ​​corresponding to the abstract parameters respectively, a target code corresponding to the service to be processed can be generated according to the plurality of abstract parameters and parameter values ​​corresponding to the abstract parameters, and the target code can be output.

[0073] S104: Output the target code corresponding to the business to be processed.

[0074] For example, when outputting the target code corresponding to the business to be processed, if the file storage type of the target code is set, the target code corresponding to the business to be processed is stored in a file of the corresponding file storage type, and the file containing the target code is output; if the file storage type of the target code is not set, the target code corresponding to the business to be processed is stored in a file of a default file storage type, and the file of the default file storage type is output, wherein the default file storage type is the file storage type set by the user last time, and can be set according to actual needs.

[0075] It can be seen that the code generation method provided in the embodiment of the present application, when generating code, first receives a code generation instruction; wherein the code generation instruction includes the identifier of the business to be processed; abstracts the business to be processed indicated by the identifier of the business to be processed to obtain a description file corresponding to the business to be processed; wherein the description file includes multiple abstraction parameters and parameter values ​​corresponding to each abstraction parameter; and generates the target code corresponding to the business to be processed according to the multiple abstraction parameters and the parameter values ​​corresponding to each abstraction parameter. It can be seen that when generating code, there is no need for technicians to manually write it, and automatic code generation is achieved, thereby effectively improving the efficiency of code generation.

[0076] Based on the above Figure 1 In order to facilitate understanding of the embodiment of the present application, how to generate the target code corresponding to the service to be processed according to multiple abstract parameters and the parameter values ​​corresponding to each abstract parameter, the following will be described. Figure 2 The illustrated embodiment describes in detail how to generate target code corresponding to the service to be processed based on multiple abstract parameters and parameter values ​​corresponding to each abstract parameter in the embodiment of the present application.

[0077] Figure 2 A flow chart of generating a target code corresponding to a pending service provided in an embodiment of the present application. The method of generating a target code corresponding to a pending service can also be executed by software and / or hardware devices. For example, see Figure 2 As shown, the method for generating the target code corresponding to the service to be processed may include:

[0078] S201. Generate code generation rules corresponding to the business to be processed according to multiple abstract parameters.

[0079] For example, when generating code generation rules corresponding to the business to be processed based on multiple abstraction parameters, the multiple abstraction parameters can be processed first to determine the abstraction parameters required for the code generation rules, that is, the target abstraction parameters. For example, if the description file is a table, the abstraction parameters at the header position of the table among the multiple abstraction parameters are determined as the target abstraction parameters; and the code generation rules corresponding to the business to be processed are generated based on the multiple target abstraction parameters. For example, if the description file is a text, the multiple target abstraction parameters can be obtained by reading the initial position of the text, and can be set according to actual needs.

[0080] According to the above embodiment, when the abstraction parameter is the specific information and quantity of the state information, condition information and execution action information contained in the code corresponding to the business to be processed, the corresponding code generation rule is the quantity information of the state information, condition information and execution action information. For example, if the abstraction parameter is 2 state information, 4 condition information and 5 execution action information, the corresponding code generation rule is that the generated code needs to include 2 states, 4 jump conditions and 5 execution actions.

[0081] In the embodiment of the present application, by determining multiple target abstraction parameters and generating corresponding code generation rules, it is possible to avoid the influence of other abstraction parameters except the target abstraction parameters on the target code. The generation rules can be used to assist in generating the corresponding target code.

[0082] In addition, in order to further improve the generation rules, it is also possible to determine the type of business to be processed, the function type of the target code corresponding to the business to be processed, the file type of the target code, and the implementation method of the target code; and according to the type of business to be processed, the function type of the target code, the file type of the target code, and the operation rules of the target code, update the code generation rules to obtain new code generation rules, which can further improve the integrity of the generation rules and better assist in generating the corresponding target code.

[0083] Among them, the type of the business to be processed, the function type of the target code corresponding to the business to be processed, the file type of the target code, and the implementation method of the target code can be determined according to the specific business. For example, the function type of the target code corresponding to the business to be processed can be in the form of void xxx_step (void), the file type of the target code can be in the form of xxx.c and xxx.h, and the implementation method of the target code can be in the form of switch...case..., and the embodiment of the present application does not make any limitation on this.

[0084] It can be seen that in the embodiment of the present application, by generating new code generation rules, its purpose is to: make the style of generated target code unified, avoid the problems of inconsistent code style and logical errors caused by multiple technicians dividing the work of writing code, and improve the efficiency of code generation.

[0085] S202: Generate a code generation tool corresponding to the code generation rule according to the code generation rule.

[0086] For example, when a code generation tool corresponding to a code generation rule is generated according to a code generation rule, the architecture of the target code corresponding to the business to be processed can be determined according to the code generation rule; and the code generation tool corresponding to the code generation rule can be generated according to the architecture of the target code corresponding to the business to be processed. The architecture of the target code corresponding to the business to be processed may include a repeated part of the generated target code, or may include other parts, and the embodiments of the present application do not impose any limitation on this.

[0087] Furthermore, when generating a code generation tool corresponding to the code generation rule according to the architecture of the target code corresponding to the business to be processed, the corresponding code generation tool can be written according to the architecture of the target code, or the corresponding code generation tool can be generated by other means. The embodiments of the present application do not impose any limitations on this.

[0088] In an embodiment of the present application, the architecture of the target code corresponding to the business to be processed is determined by code generation rules, and a corresponding code generation tool is generated, so that the corresponding target code can be generated by the code generation tool, thereby improving the accuracy and efficiency of the generated code.

[0089] S203: Generate target code corresponding to the service to be processed according to the description file and the code generation tool.

[0090] For example, when generating the target code corresponding to the service to be processed according to the description file and the code generation tool, the description file can be imported into the code generation tool to generate the target code corresponding to the service to be processed.

[0091] Among them, the code generation tool can first determine the multiple target abstraction parameter values ​​required by the target code according to the parameter values ​​corresponding to the multiple abstraction parameters in the description file, and piece together the multiple target abstraction parameter values ​​with the architecture of the target code corresponding to the business to be processed, or add the multiple target abstraction parameter values ​​to the architecture of the target code, so as to generate the target code corresponding to the business to be processed. The specific generation method can be set according to the actual situation. By importing the description file into the code generation tool, the code tool generates the target code corresponding to the business to be processed according to the parameter values ​​corresponding to the abstraction parameters in the description file, avoiding the problem of errors in manually written code and improving the efficiency of code generation.

[0092] To summarize, the code generation method provided in the embodiment of the present application, when generating the target code corresponding to the business to be processed according to multiple abstract parameters and the parameter values ​​corresponding to each abstract parameter, first generates the code generation rules corresponding to the business to be processed according to the multiple abstract parameters; and generates the corresponding code generation tool according to the code generation rules; and generates the target code corresponding to the business to be processed according to the description file and the code generation tool, which can avoid the time-consuming and high error rate problems caused by manual code writing, and improve the efficiency of code generation.

[0093] In order to facilitate understanding of the code generation method provided in the embodiment of the present application, the following will take the specific application of the method in practice as an example to describe in detail the technical solution provided in the embodiment of the present application. Figure 3 As shown, Figure 3 A flowchart of another method for generating code provided in an embodiment of the present application.

[0094] A scheduler may be used in the code generation to ensure that the division of labor among various software and / or hardware devices in the code generation process is clear, thereby improving the efficiency of code generation. Figure 3 The scheduling definition in , that is, when receiving the code generation instruction, the type of the pending business and the identifier of the pending business can be determined, and the state information, condition information and execution action information corresponding to the pending business can be determined by parsing the pending business. Assume that the state corresponding to the pending business is represented by S, the condition is represented by C, and the execution action is represented by A.

[0095] For example, state S may include initialization state S0 and multiple running states S1 to Sn, condition C may be a state jump condition between each state S, Cx_y represents the jump condition from state Sx to state Sy, for example, C1_2 represents the jump condition from state S1 to state S2. Each state S includes three sub-states, namely initialization sub-state en, running sub-state du, and exit sub-state ex. The execution action A is the action performed for each sub-state, wherein the action of executing initialization sub-state en may be Aen_1 to Aen_n, indicating that the actions of initialization sub-state 1 to sub-state n are executed in sequence; the action of executing running sub-state du may be Adu_1 to Adu_n, indicating that the actions of running sub-state 1 to sub-state n are executed in sequence; the action of executing exit sub-state ex may be Aex_1 to Aex_n, indicating that the actions of exiting sub-state 1 to sub-state n are executed in sequence.

[0096] It can be understood that the above state jump conditions are the corresponding conditions in the actual code, and the execution action is the function interface provided by the basic software layer. The relationship between the state, condition and execution action can be seen in Figure 4 As shown, Figure 4 A schematic diagram of a code execution flow provided in an embodiment of the present application.

[0097] according to Figure 4 As shown, during the code running process, the actions of the initialization substate en in the initialization state S0 are first executed in sequence, that is, the actions of the initialization substate 1 to the initialization substate n are executed in sequence. After completing the initialization of the substates, the actions of the running substate du in the initialization state S0 are executed in sequence, that is, the actions of the running substate 1 to the running substate n are executed in sequence, and the actions of running n substates in sequence are performed in a loop until the jump condition C=C0_x is received. After receiving the jump condition, the actions of the running substate in the initialization state S0 are stopped in sequence, and the actions of the exit substate ex in the initialization state S0 are executed in sequence, that is, the actions of the exit substate 1 to the exit substate n are executed in sequence. Among them, the jump condition can be to jump from the initialization state S0 to the state S1, or it can be to jump from the initialization state S0 to the state S1. The embodiment of the present application does not impose any limitation on the specific jump condition.

[0098] After executing the exit actions of multiple sub-states in the initialization state S0, the state jumps according to the specific jump condition. If the jump condition is C=C0_1, the initialization state S0 jumps to state S1, and runs according to the code running mode in state S1, and according to the received jump condition C=C1_2, jumps from state S1 to state S2, and runs according to the code running mode in state S2. If the jump condition is C=C0_2, the initialization state S0 jumps to state S2, and runs according to the code running mode in state S2, and according to the received jump condition C=C2_1, jumps from state S2 to state S1, and runs according to the code running mode in state S1. According to Figure 3 As shown, the code operation mode in state S1 and state S2 is the same as the code operation mode in the above-mentioned initialization state S0, and the embodiment of the present application will not be repeated here.

[0099] in, Figure 4 The jump conditions shown can be jumped simultaneously or in a certain time sequence, and the embodiments of the present application do not impose any limitations on this.

[0100] according to Figure 3 As shown, after the scheduling definition is performed, a scheduling description file can be established, that is, according to the above analysis results of the pending business, a description file corresponding to the pending business is obtained. Among them, the scheduling description file can be shown in the following Table 1. Table 1 is a scheduler state table, which includes the number of states of generating code, initialization state actions and their corresponding numbers, and execution state actions and their corresponding numbers.

[0101] Table 1

[0102]

[0103] Table 1 includes multiple abstract parameters and parameter values ​​corresponding to each abstract parameter, wherein the table header in Table 1 is divided into multiple abstract parameters, namely, state identifier, state number, initialization action identifier, initialization action 1, initialization action 2, execution action identifier, execution action 1, and execution action 2. Each parameter value corresponding to the abstract parameter is the value of the column where each abstract parameter is located, for example, the parameter value corresponding to the state number is 0, 1, and 2.

[0104] In addition, the scheduling description file also includes a scheduler state migration table, as shown in Table 2 below.

[0105] Table 2

[0106]

[0107] Table 2 also includes multiple abstract parameters and parameter values ​​corresponding to each abstract parameter, wherein the abstract parameter is the header part of Table 2, that is, the abstract parameters are state jump identifier, current state, target state, jump condition, exit state action identifier, exit state action 1, and exit state action 2. The parameter value is the value of each abstract column, for example, the parameter value corresponding to the abstract parameter jump condition is C==C0_1, C==C0_2, C==C1_2, C==C1_0, C==C2_0, and C==C2_1.

[0108] Determine the target abstraction parameters according to Table 1 and Table 2, where the target abstraction parameters are state number, initialization action 1, initialization action 2, execution action 1, execution action 2, current state, target state, jump condition, exit state action 1, and exit state action 2, and generate corresponding code generation rules according to the target abstraction parameters.

[0109] For example, to further improve the generated code generation rules, in addition to the abstraction parameters shown in Table 1 and Table 2 and the parameter values ​​corresponding to each abstraction parameter, the parameters of the scheduler need to be set. The parameters of the scheduler can be set through the parameters in the following Table 3, which is a scheduler design table.

[0112] According to the parameters in Table 3, the code generation method of the embodiment of the present application can be implemented by a state machine, and the number of state machines is consistent with the number of states in Table 3. The state jumps, state jump conditions, and execution actions of each state of the state machine during operation are consistent with the parameter values ​​corresponding to the abstract parameters in Tables 1 and 2. Among them, according to the state variable names in Table 3, the state machine in the embodiment of the present application is in the form of switch...case...

[0113] It is understandable that the generated code generation rules can be updated and improved according to the parameters of the scheduler shown in Table 3 to obtain new code generation rules. For example, when updating the code generation rules, other parameters of the generated code can also be set. For example, the generated target code contains a .c and a .h file, and the generated file names are xxx.c and xxx.h, respectively, where xxx is the scheduling name; and type.h and util.h header file references need to be added to xxx.h so that the data type corresponding to the embedded chip is consistent with the system definition; the target code can be an independent function, and the function name can be in the form of void xxx_step (void), and the function needs to be marked in xxx.h. The embodiment of the present application only updates the generated code generation rules using the above parameters as an example, but it does not mean that the embodiment of the present application is limited to this.

[0114] according to Figure 3 As shown, after generating new code generation rules, write the corresponding code generation tool according to the new code generation rules, and import the scheduling description files shown in Tables 1 and 2 into the code generation tool. The code generation tool can automatically generate code by reading the parameter values ​​corresponding to the target abstraction parameters, that is, generate the target code corresponding to the business to be processed.

[0115] The target code generated according to the above method is:
