[0033] As previously mentioned, scenario-based automatic code generation models based on large models are all oriented towards general-purpose, text-based languages ​​such as C / C++ / JAVA / Python. Currently, scenario-based automatic code generation models based on large models have not yet achieved code generation capabilities for specialized languages ​​that meet international standards in the industrial control field. To this end, this application proposes a code generation method and apparatus, electronic equipment, and non-transitory computer-readable storage medium.

[0034] According to an embodiment of the present application, a structured text code dataset that complies with international standards in the field of industrial control is first constructed, and the constructed structured text code dataset is used to train a scenario-based code automatic generation model based on a large model, so that the scenario-based code automatic generation model based on a large model supports the output of structured text language code that complies with the standards.

[0035] According to other embodiments of the present application, by constructing a code block mapping table corresponding to the four arithmetic operations, logical operations and / or shift operations of the structured text code, the standard-compliant structured text language code output by the scenario-based code automatic generation model based on the large model can be converted into a graphical function block diagram that complies with international standards in the field of industrial control.

[0036] According to other embodiments, the development efficiency of industrial control applications is improved by compiling, running, and verifying the generated structured text code and / or graphical function block diagram.

[0037] The specific embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0038] FIG1 shows a method flow chart of a code generation method according to an exemplary embodiment of the present application. The following takes FIG1 as an example to describe in detail a code generation method according to an exemplary embodiment of the present application.

[0039] As shown in FIG. 1 , in step S101 , a structured text code data set conforming to a preset industrial control international standard language is constructed.

[0040] In one embodiment, based on an existing industrial control program asset library that complies with an international industrial control standard language, a structured text algorithm library that complies with a preset international industrial control standard language is formed, wherein the structured text algorithm library includes function and function block codes that comply with the IEC61131-3 standard definition.

[0041] According to some other embodiments, a structured text code data set conforming to a preset industrial control international standard language is generated using a preset conversion tool, wherein the conversion tool is configured to convert C language into a structured text language conforming to the industrial control international standard language.

[0042] In a specific embodiment, a conversion tool is first developed to convert C language into structured text language; then, keyword mapping and statement equivalence conversion are used to convert the open source C code into a structured text language that conforms to the preset industrial control international standard language, thereby forming an open source industrial control standard language code library.

[0043] Since structured text does not support dynamic memory allocation, in a specific embodiment, first, the code involving dynamic memory allocation is modified to static allocation and then converted into structured text code.

[0044] Step S103: training a preset model using the structured text code dataset.

[0045] According to an embodiment of the present application, the model in step S103 includes an open source low-parameter large model, for example, a conversational language model Chatglm-6B, Llama2-7B and / or CodeT5+ model that supports question and answer.

[0046] In step S103, in one embodiment, model training is performed on the open source low-parameter large model, and the trained model is deployed to the server.

[0047] Specifically, we use a prompt optimization method to train an open-source, low-parameter, and large-scale model. That is, by designing and optimizing a set of prompts, we enable the pre-trained model to perform a specific task.

[0048] Step S105 , generating structured text code that complies with the industrial control international standard language using the trained model according to the user's input data.

[0049] According to an embodiment of the present application, in step S105, a human-computer interaction interface is used to obtain the user's input prompt content, and the obtained input prompt content is sent to the model trained in step S103. The model trained in step S103 is used to push the user's input prompt content and generate a structured text code that conforms to the industrial control international standard language.

[0050] In a specific embodiment, the model trained in step S103 can run on a single GPU or multiple GPUs and support parallel reasoning, as shown in FIG2 .

[0051] The model execution system structure diagram shown in Figure 2 uses a BS architecture. The prompt content entered by the user on the client is submitted to the service process on the server. The service process uses a multi-threaded mode of first-come, first-served mode to process multiple user inputs and calls the model trained in step S103 for inference. The results are then returned to the client.

[0052] According to the embodiment shown in Figure 1, a structured text code dataset that complies with international standards in the field of industrial control is first constructed, and the constructed structured text code dataset is used to train a scenario-based code automatic generation model based on a large model (that is, an open source low-parameter large model) so that the scenario-based code automatic generation model based on the large model can output structured text language code that complies with the standards.

[0053] FIG3 shows a method flow chart of another code generation method according to an example embodiment of the present application. In addition to steps S101 to S105, the code generation method shown in FIG3 also includes step S107. For the sake of brevity, only the differences between the embodiment shown in FIG3 and FIG1 will be described below, and a detailed description of the similarities will be omitted.

[0054] In this embodiment, in step S107 , the structured text code generated in step S105 and conforming to the industrial control international standard language is converted into a function block graphic program.

[0055] According to the embodiment shown in FIG3 , by converting the standard structured text language code into a graphical function block diagram that complies with the international standard in the field of industrial control, the guided generation function of the graphical program that complies with the international standard language for industrial control is realized.

[0056] Figure 4 shows a flow chart of a method for converting structured text code in accordance with an international standard language for industrial control into a function block graphical program according to an exemplary embodiment of the present application. As shown in Figure 4 , the above step S107 includes sub-steps S1071 to S1073 .

[0057] In sub-step S1071, a code block mapping table corresponding to the four arithmetic operations, logical operations, shift operations, loop statements and / or flow control statements of the structured text code is constructed, wherein the code block mapping table includes a function mapping table and / or a function block mapping table.

[0058] For example, the four arithmetic operation symbols +, -, *, / , and MOD are converted using the standard function symbols ADD, SUB, MUL, DIV, and MOD in sequence to establish a code block mapping table corresponding to the four arithmetic operation symbols.

[0059] For another example, the AND, OR, XOR, and NOT logical operators are converted in sequence using the AND, OR, XOR, and NOT standard functions to establish a code block mapping table corresponding to the logical operators.

[0060] For another example, the comparison operators <, >, <=, >=, =, and <> are converted using the LT, GT, LE, GE, EQ, and NE standard functions in sequence to establish a code block mapping table corresponding to the comparison operators.

[0061] Another example is converting loop statements using the "label + jump symbol + function subgraph" structure. Specifically, as shown in Figure 5, for a FOR statement, the graph segments are divided according to the initial value assignment of the loop indicator variable, the self-increment or self-decrement of the loop statement, the loop statement block execution, and the loop exit judgment. For a WHILE loop statement, it can be converted to a FOR statement first and then converted.

[0062] For another example, for flow control statements, such as IF-ELSE-END_IF statements, a logic diagram is first formed for each IF-ELSEIF expression, with the output of the expression logic diagram being a BOOL value. Next, a jump priority diagram is constructed for each IF-ELSEIF branch expression, as shown in Figure 6. If the IF branch condition is met, execution jumps to the graphical program corresponding to the IF statement block. If the IF branch condition is not met, and the ELSEIF1 branch condition is met, execution jumps to the graphical program corresponding to ELSEIF1, and so on. If all branch conditions are not met, execution jumps to the graphical program corresponding to the ELSE branch. For SWITCH-CASE statements, these can be converted to IF-ELSE-END_IF statements before conversion.

[0063] In sub-step S1073, the structured text code is parsed to generate a syntax tree.

[0064] It should be noted that the method for generating a syntax tree is not limited here, and any method for parsing structured text code and generating a syntax tree is applicable to the embodiments described in this application.

[0065] In sub-step S1075, the syntax tree is traversed and, based on the constructed code block mapping table, the arithmetic operations, logical operations, shift operations, loop statements, and / or flow control statements in the structured text code are converted into a topological diagram of function block symbols and data connections. The data refers to the output of a function / function block symbol after operation, which is passed to the input of other function / function block symbols, and refers to the topological connection relationship between symbols.

[0066] In some embodiments, in sub-step S1075, the syntax tree generated in sub-step S1073 is traversed in depth-first order.

[0067] According to the embodiment shown in FIG4 , a syntax tree is generated by parsing a structured text, and the syntax tree is traversed in depth-first order. According to the code block mapping table corresponding to the four arithmetic operations, logical operations, and shift operation symbols of the constructed structured text, basic binary operations and ternary operations are converted into function block symbols and data connection topology diagrams. Labels + jump symbols + function subgraphs are used to convert loop statements, and BREAK, EXIT, and CONTINUE symbols are used to convert process control statements, thereby realizing the guided generation function of a graphic program that conforms to the international standard language for industrial control.

[0068] According to other embodiments of the present application, after obtaining the structured text code shown in FIG1 or the functional block diagram program shown in FIG3 , a debugger can be compiled and run to confirm the correctness of the program's functionality. If fine-tuning is required, the input prompt content can be adjusted and all or part of the steps of FIG1 or FIG3 can be repeated.

[0069] According to the embodiments of the present application, the development efficiency of industrial control applications is improved by compiling, running, and verifying the generated structured text code and / or graphical function block diagram.

[0070] The embodiments of the present application are described above mainly from the perspective of methods.
